2012 Research Yearbook Thesis Projects

Transcription

Foreword
MS/PhD are completely different from other programmes at IIT Madras. These are
the research based programmes and the scholars acquire the capability of finding
solutions to those problems that are encountered in industries, by applying the
theory studied earlier. So, every scholar does a minimum required course work and
then takes up a problem. Every scholar works on an unique problem. Every scholar
is different from the other, in terms of their work. Despite these differences, they are
similar as they have to apply their knowledge of various subjects and this creates a
overlap of knowledge among the scholars. During the process of this problem
solving a scholar will go beyond the subjects he/she would have studied, as many
times they need to take the refuge in a different discipline to get to the solution. This
makes a scholar good in various disciplines at the same time. All these and much
beyond these, raise the requirement to get a much desired individual attention to a
scholar, from the world outside. That is why this special book for research scholars !
This year book contains the profiles of scholars who would graduate before 2013.
Hoping that the book would serve its purpose....

Title of thesis : Numerical Investigations on Regression Rate Enhancement in Hybrid Rocket Motors
Thesis abstract : Hybrid rockets are the safest rockets combining the potentials of both solid and liquid rocket
motors. However they are not commercially successful due to its very low regression rate. Current research in
hybrid rocket motors is mainly focused on enhancing the regression rate by various techniques like, diaphragms
in the port, swirling flow in the combustion chamber and oxidizer added solid fuel. The underlying fundamental
physics in most of these configurations is not understood completely. Effect of parametric variations in individual
techniques is not clearly quantified. Study on combination of these techniques also has not been attempted. In
the present study, an attempt has been made to understand the effect of these techniques on the regression rate
of hybrid rocket motors. A systematic numerical study is conducted using ANSYS Fluent. The gas phase
combustion chamber is chosen as the computation domain where the governing equations are solved. Custom
written user defined functions (UDFs) are used to augment the boundary conditions.
In the parametric study
conducted, the following parameters are varied systematically: height and axial location of a single diaphragm,
height and spacing between multiple diaphragms, swirl number at the oxidizer inlet, axial and swirl velocity
profiles at the oxidizer inlet, percentage of solid oxidizer mixed with the solid fuel, and the length, diameter and
L/D ratio of the combustion chamber. Regression rate enhancements over the base configuration (one without
any enhancement techniques) are quantified for each of the regression rate enhancement techniques. Studies are
also carried out with a combination of different enhancement techniques and the results are compared with base
configuration as well as configurations with single enhancement technique.

Title of thesis : Interaction of flames with varying stratification and grid generated turbulence
Thesis abstract : The drive towards low pollution levels of oxides of nitrogen has led to lean premixed flames
being established in practical combustion devices such as land-based gas turbines for power generation, but they
pose immense problems of flame stability. Devices such as flight gas turbine combustors adopt injection of fuel
almost directly into the combustion zone, but with intense fuel-air mixing caused by swirl flow, leading to partially
premixed flames that are relatively stable. In many practical processes, the combustion is turbulent rather than
laminar. Nevertheless, the investigation of laminar partially premixed flames is a prerequisite to understand their
turbulent counterparts. Hence present investigation is divided into two objectives, primary one to understand the
turbulence flame interaction and second to investigate laminar partially premixed flames. Co-flowing methane–air
partially premixed flames are stabilized in a splitter plate burner (dimension 50 mm x 50 mm), with wide variation
of the reactant concentration gradient. Triple flame is a special case of partially premixed flames; such flames with
wide range of reactant premixedness are obtained. The velocity field is deduced from particle image velocimetry
(PIV) and the flame structure is visualized by means of laser induced florescence of the OH radical (OH-PLIF).
The flame structure changes from that of a nearly non-premixed to a nearly premixed flame as the concentration
gradient is varied. The flame curvature increases linearly with the concentration gradient over the wide range
tested. Flame speed is evaluated from the velocity just upstream of flame leading edge. Flame stretch, which is
nothing but tangential strain along flame front is obtained. In later work perforated plate is used to generate
turbulence, present burner can stabilize turbulence partially premixed flames. Here simultaneous OH-PLIF PIV is
performed, which involves sophisticated instrumentation for synchronization of the data acquisition events. Data is
processed with MATLAB software; it involves image processing, edge detection and noise reduction.
Simultaneous measurement of flame front and velocity provides accurate information; velocity at the flame leading
edge is obtained which is nothing but turbulent flame speed. To generate large scale turbulence a large splitter
plate burner 220 mm x 220 mm was employed, it accommodates active turbulence grid (ATG). Unlike passive
grid, ATG has moving parts; winglets are mounted on each grid rod. These rods are rotated randomly by a
stepper motor; LabView program controls each one of the 24 stepper motors. ATG provides means of creating
random blockage to the flow. By controlling the speed range and turnover time range turbulence quantities can be
controlled to some extent. This provides a turbulence control without changing mean flow velocity which is not
possible with passive grid but at the cost of complexity. ATG will be used for fewer flames due to high fuel
consumption.

About me :
Since my Diploma education I have enjoyed the Mechanical Engineering. Experience in Mahindra and
Mahindra taught me to anticipate the issues, so one can be well prepared even before things go wrong. When the
tractor prototype scheduled for assembly on production line, many issues showed up, this led to loss of
production. I have been told that I am good at managing the task with available resources. For example
performing complicated experiments first time in our lab proved to be a challenge, but dividing the task into
subparts eased the problem. At many occasion lab required the purchase and commissioning of equipments such
as lasers, high capacity chiller etc. Such activity requires co-ordination and follow-ups among purchase
department and supplier. This experience was valuable; I learned to expedite the purchase and installation
process. My career goal is to learn and implement a new knowledge. I believe that the research conducted in
past century has led to better quality of life. In this spirit I want to engage myself with the research oriented firm.

Title of thesis : Supersonic Flow over Three Dimensional Cavities
Thesis abstract : Keywords: 3D cavities, supersonic flow, pressure oscillations, mixing Airbreathing propulsion
devices employing scramjet is considered potentially most advantageous for practical hypersonic flights. Cavities
have been projected as flameholding and mixing devices in scramjet combustors. Performance of cavities used
for such purposes is significantly influenced by the aerodynamics induced by the cavity on the flow field. Pressure
oscillations, shock and expansion waves, unsteady shear layer dynamics are some of the key features of flow
over wall mounted cavities. Dependence of such aerodynamic characteristics on geometrical features of cavities
has been studied widely in the recent decades. The present investigation primarily focuses on the flow and
acoustic characteristics of partially spanning wall mounted cavities designated as 3D cavities. Effect of cavity
width (W) on mixing of primary supersonic flow and a gaseous injectant has also been studied for cavities with
constant length (L) to depth (D) ratio. The results are compared with those from a cavity which spans the full width
of the test section, called as 2D cavity.
The study has been carried out making use of the supersonic
freejet facility in the Gas Dynamics Laboratory of Indian Institute of Technology, Madras. Three different 3D
cavities of 50mm length (L) and 25mm depth (D) having length to width ratios (L/W) of 2, 3 and 4 and a 2D cavity
of L/W=5/6 were used in the experimental investigation. Each of the cavities was wall mounted in a rectangular
channel and flow in all the cases was at Mach number of 1.7. Unsteady pressure measurements, time resolved
and time averaged visualization of the flow field, velocity measurements using Laser Doppler Velocimetry and Mie
scattered imaging for mixing evaluation and pressure loss measurements were carried out. Numerical simulation
of the test section flow field was undertaken using commercially available computer code FLUENT.
It is
observed from the unsteady pressure measurements that the magnitude and mode of the pressure oscillations
depend on the cavity geometry. There is a jump in the mode of the dominant pressure oscillation to a higher value
as the cavity width reduces. Images captured during time averaged schlieren visualization show marked
difference in the shear layer thickness and shock wave angle at the leading edge as the cavity width changes.
Acoustic wave inside the cavity, flapping movement of the shear layer and the overall unsteady nature of the flow
field could also be seen in the visualization images Disturbances generated in the flow field due to the presence of
the cavity are observed to be subdued for the narrowest cavity model.
Fluid movements in lateral planes
inside the cavity and over it are investigated by the velocity measurements at discrete points on multiple planes
using Laser Doppler Velocimeter. Presence of lateral velocity in the vicinity of the leading and trailing edges only
is observed for narrower partially spanning cavities. Fluid movement in the lateral direction over the cavity is
observed to be at different velocities for the different cavity models. Turbulence induced in the flow field by the
widest partially spanning cavity is observed to be higher. Quantum of mixing of a secondary gaseous injectant into
the primary flow which usually depends on the flow unsteadiness varied with cavity width. The widest partially
spanning cavity offered better mixing. Associated total pressure loss with this cavity is observed to be higher than
that with the other models.
Flow in the test section for all the models has been simulated using
commercially available software FLUENT. The variation of density and pressure along the axial midplane of the
test section show good agreement with the experimental flow visualization results. Vortical structure on the axial
midplane inside the cavity is observed to be larger for the wider cavity. The fluid mass exchange rate (mc)
between the cavity and the freestream depended on the cavity width. Larger mass exchange was observed for
the wider cavities. The ratio of mc to the cavity volume is found to influence the amplitude of cavity generated
pressure oscillations.

Title of thesis : EXPERIMENTAL AND NUMERICAL INVESTIGATION OF GASEOUS INJECTION INTO
SUPERSONIC FLOW USING STRUTS AND PYLONS
Thesis abstract : KEY WORDS: Supersonic mixing; struts, pylons, streamwise vortices, Mixture fraction, Degree
of Unmixedness, Percentage of Mixing Area, LDV, Turbulence intensity. The scramjet combustors require rapid
and uniform mixing of the fuel and air for augmented and stable combustion within short combustor lengths. A
number of methods are proposed earlier for mixing and entrainment of the fuel. In the present work experimental
and numerical studies are done on mixing of sonic injectant from struts and pylons of various trailing ramp angles
with free stream air at Mach number 1.63. By providing alternate trailing ramp on the strut and pylon streamwise
vortices in spanwise row-configuration are generated. In the present study various alternate trailing ramp struts
and pylons were examined and their capability to enhance supersonic mixing was evaluated. Numerical
simulation of the flow field using commercially available software Fluent with struts and pylon of various trailing
ramp angles such as 2.86, 5.71, 8.53, 11.31, 14.04, 18.43 and 26.57 degrees are also carried out. From the
numerical results, it is seen that among the models analyzed mixing enhancement is best for the strut and pylon
with 14.04 degrees ramp angle while comparing with plain strut and plain pylon. Experiments were conducted
using struts and pylons of 14.040 ramp angle only. All the experimental investigations were carried out in the
supersonic blow down free jet facility of Gas Dynamic Laboratory, IIT Madras. The secondary injections from the
struts and pylons were parallel to the main stream at sonic conditions. Three types each of struts and pylons are
considered for the experimental investigation - plain strut and plain pylon, two relieved ramp strut and pylon
(2RRS/2RRP-14.040) and three relieved ramp strut and pylon (3RRS/3RRP-14.040). Diagnostic methods
employed are Mie scattering combined with image processing, time-averaged schlieren and time-resolved high
speed shadowgraph images, velocity measurement using LDV and total pressure loss measurements. The
Degree of Unmixedness (DU) and Percentage Mixing Area (PMA) results obtained from the Mie scattering studies
show that three relieved ramp strut and pylon (3RRS/3RRP) give better mixing performance while comparing with
other strut and pylon configurations. The vertical structure that could be found in the numerical analysis of the flow
fields were identified well from the velocity vectors obtained from the velocity measurements. From LDV
measurements it is also understood that alternative trailing ramp on struts and pylons increases turbulence
intensity when compared with plain strut and plain pylon. Increased turbulence is an important reason for the
better mixing performance of the struts and pylons. Plain strut and Plain pylon show the least total pressure loss
when compared with models having trailing ramps. Overall, struts show better mixing performance than all pylon
configurations.

Title of thesis : EXPERIMENTAL STUDIES HIGH SPEED AIR INTAKES
Thesis abstract : In supersonic and hypersonic vehicles, intake plays a major role in order to give better
performance. All air breathing engines require an inlet to diffuse air from free stream velocity to a lower velocity
acceptable for further use. The inlet component is designed to capture exact amount of air required, with minimum
pressure loss, deliver the air with minimum flow distortion. All most every type of high speed air intakes
(supersonic and hypersonic) experiencing shock oscillation during operation called as inlet buzz. Inlet buzz can
occur due to several reasons such as large internal area contraction ratio, serious shock-boundary layer
interactions, and high back pressure. Inlet buzz is highly undesirable phenomena which can lead to reduction of
thrust and even damages the structure. Hence detailed study of inlet buzz should be necessary. . The main focus
of this research is to suppress the buzz by changing the cowl deflection angle, and understanding the flow field
inside the duct. Buzz can be suppressed by changing the cowl deflection angle, at a particular cowl deflection
angle, buzz will disappear and flow field will be smooth. It is not seen any experimental literature regarding buzz
suppression by using cowl deflection angle.

Title of thesis : Modelling the coupled static and dynamic response of stiffened sandwich composite panels
Thesis abstract : A sandwich structure consists of two thin, sti ff and strong face sheets connected by a thick ,
light and low-modulus core using adhesive joints. The main advantage of a sandwich structure is its exceptionally
high flexural sti ffness-to-weight ratio compared to other architectures. But a major disadvantage when compared
with monolithic composites is that they are more prone to delamination and failure due to the presence of large
weak interfaces between adjacent materials. The strength and stiff ness discontinuity at the face sheet-core
interface results in large increase in shear stress. This stress concentration can be controlled by varying the core
properties through the thickness by using a functionally graded core. Sandwich construction is extensively used
for the skin and web of a horizontal axis wind turbine blade. For the design of very large wind turbine blades in
future, researchers have proposed extending the use of sandwich materials to the spar flange or spar cap.
Incorporating these changes, an accurate and efficient analytical modelling and structural analysis method for
wind turbine blade is necessary. The present work is aimed at developing an analytical model for such a wind
turbine blade cross section. The blade cross section is modelled as a sti ffened closed shell made of sandwich
composites. The modied Hamiltonian type Hellinger-Reissner variational principle is used to develop the
Hamiltonian canonical equation for the system. This method is based on a mixed variational principle that includes
the variations of both displacements and stresses. Finite element approximation is introduced only for the in-plane
variations of displacements and stresses, while the through-thickness distributions of them are obtained by using
the method of state equation. Solving these equations the coupled static and dynamics response of the stiffened
sandwich composite panel is investigated.

Title of thesis : Effect of geometry in a supersonic diffuser having shock oscillation across second throat
Thesis abstract : Supersonic diffusers appear in aircraft gas turbines, ramjets and wind tunnels etc. In such
cases, depending on the disturbances present upstream or downstream of the diffuser there can be shock waves
oscillations in the channel and the position of the normal shock wave decides the start or unstarts of the diffuser
flow. Therefore it has practical importance to understand the origin and consequence of these oscillations.There
are several factors which affect the oscillation such as shock wave-boundary layer interaction, mach number of
the flow, geometry of the section, etc. The dynamics of this shock oscillations can be studied experimentally by
varying the geometric profile of the diffuser.

Title of thesis : Numerical simulation of sandwich propellant combustion
Thesis abstract : In the recent years there has been a renewed interest on burning behavior of heterogeneous
solid propellant. In the modern day launch vehicles solid rocket are used as the primary boosters. Solid propellant
technology is also used in the strategic missiles. In spite of wide range of applications, complex combustion and
flow processes involved have posed considerable challenge. To get better understanding of the combustion
processes involved in heterogeneous solid propellant this study is carried out. The burning Heterogeneous Solid
propellant, a mixture of Ammonium Perchlorate (AP) and Hydroxyl Terminated Poly Butadiene (HTPB), is being
simulated for sandwich geometry of HTPB and AP using Finite Volume method. The equations governing the fluid
flow, energy and species balance are solved in the gas phase. The gas is assumed to follow the ideal gas
behavior. The gas phase field is coupled with the condensed phase energy balance through the connection
conditions at the regressing interface. The combustion in the Gas phase takes place through a three step, finite
rate, irreversible three step chemical reaction governed by an Arrhenius Law .The overall Chemical Kinetics
scheme for the surface pyrolysis and Gas phase reactions are similar to the one described in the BDP model
which involves Three step gas phase reactions and two surface pyrolysis reactions. The unsteady non-planar
regression interface is tracked by solving the Level set equation. Solid fuel is assumed to undergo pyrolysis at the
interface and converts into gas phase directly without melting. Simulation is carried out at constant background
pressure. Burn rate behavior of the propellant is studied at different background pressure value. As burning take
place interface is being tracked with time.

Title of thesis : Coupled FEM-CFD aero-elastic modeling of 2 MW Horizontal Axis Wind Turbine (HAWT) Rotor
with initial curvature in Unsteady Aerodynamic Effects.
Thesis abstract : The increasing demand for higher efficient and lower cost of wind power has motivated the
design and manufacture of multi-megawatt horizontal axis wind turbines (HAWT) with large rotor diameter.The
wind turbine is a flexible structure whose components deform under the action of the aerodynamic loads Hence,
the aeroelastic response of the blades has a decisive influence on the overall system dynamics.The aeroelastic
response of the blade has to be modelled using improved unsteady aerodynamic models for effects such as
dynamic stall, Reynold's number effects and wake turbulence. This requires the use of numerical tools such as
CFD and FEM. The HAWT rotor blade has been designed using modified blade element momentum theory
(BEMT) of NACA 5 digit aerofoil. Dynamic stall of the wind turbine airfoil has been predicted using unsteady
aerodynamic ONERA model.Rotor model and structured mesh for both fluid and structure have been generated in
ICEM CFD. Stress analysis and modal analysis have been performed in the ANSYS using SHELL181 element.
Large eddy simulation (LES) turbulence model has been used for CFD analysis in FLUENT. To analyse the real
time situation,Two way coupled fluid-structure interaction (FSI) has been performed using ANSYS FLUENT and
Transient structure. At each time step, the aerodynamic load has been calculated by fluent and the corresponding
force has been transfered to the trasient structure on the fluid-structure interface results in displacement of the
rotor structure.Now, for this deformed rotor structure a new aerodynamic load has been calculated in the next time
step.This simulation has been performed for 10 sec for a wind speed of 10 m/s and at a rotor speed of 25 RPM

Title of thesis : Aeroelastic Stability and Fatigue Damage estimation of Wind Turbine Blades.
In the design of wind turbine structures, aeroelastic stability is of utmost importance. It

becomes even more crucial when there are uncertainties involved in it. An airfoil with its pitch-plunge flexibility is
considered under potential flow. The potential flow model is justified as the classical flutter model involves
unseparated flow over the body so that inviscid assumptions are valid. The flow-field is simulated with an
unsteady vortex lattice method (UVLM) which considers a freely developing wake behind the airfoil, as a result the
unsteady aerodynamic load calculations are more accurate than the analytical models.
This unsteady flow
solver is combined with the structural dynamic governing equations to simulate the fluid-structure interaction
effects and calculate the system response after solving the combined equations in the time domain using a time
integration routine. Analytical models are based on the classical wake model of Wagner which considers rigid
wake and also simplifies the shape of the airfoil as a flat plate. The UVLM potential flow code has been validated
with earlier results available in the literature.
The values of the linear flutter speed predicted by using UVLM
code is in close agreement with that of the analytical fixed wake model. When structural nonlinearities are
present, the system exhibits a self sustained oscillation of constant amplitude called as Limit Cycle Oscillation
(LCO) even beyond the linear flutter speed. This nonlinear system is subjected to a horizontal gust with a von
Karman spectra using the well known model of Shinozuka and Jan. The phases in this random process model are
uniformly distributed random variables. In the present study, the phases have been generated only once and the
same values are used in all the realizations.
The vertical component of the gust is assumed to be zero.
Structural uncertain parameters have been modeled as Gaussian random variables. A spectral uncertainty
quantification tool called Polynomial Chaos Expansion is used to quantify the effect of uncertainty propagation
and calculate the response statistics. A non-intrusive version of the method using stochastic projection approach
is used to capture the response time histories and compute the response statistics at various time instants and
compared with standard Monte Carlo Simulation as a reference solution. The system response by both the
analytical and higher fidelity UVLM model subject to the same uncertainties are compared and an estimate of
fatigue damage is obtained from the uncertain response. In order to do that, rainflow cycle counting procedure is
used.

Title of thesis : Effects of External Heat Sink and Heat Source onOpposed Flow Flame Spread over Thin Solid
Fuels
The study of flame spread phenomena is primarily driven by the need to have better fire
Thesis abstract :
safety, by means of enhanced understanding of mechanisms that control the spread rate and extinction. In almost
all of flame spread studies a single fuel sheet is taken to understand the flame spreading mechanisms and
flammability of solid materials. However, in practical situations spreading flame may interact with nearby cold
surfaces or nearby flames which will influence the flame spread rates and extinction limits. This has not been
investigated especially in microgravity where such interaction can have major implications.
Here in this work
flame suppression is investigated by placing a metal wire-mesh parallel to the fuel surface. This metallic mesh
acts as a flame extinguishing barrier by absorbing away heat from the flames and thus reducing heat feedback to
unburnt fuel. If the heat feedback is reduced sufficiently, pyrolysis of fuel will be reduced to the extent that flame
cannot self-sustain and therefore extinguishes. Likewise interaction of flames spreading over parallel sheets of
fuel is likely to alter the flame spreading behavior and flammability map from that of a single fuel sheet. A parallel
fuel sheet acts as heat source by releasing away heat from the flames and thus enhancing heat feedback to
unburnt fuel. This heat feedback increases pyrolysis of fuel resulting stronger flame.
An existing 2-D opposed
flow flame spread model of Kumar et al. comprising of solid phase model and gas phase model was adopted. The
existing numerical model was formulated with equations governing the physical processes and modeled with a
gas phase heat sink (a metallic wire-mesh) and a heat source (a parallel burning fuel) to analyze their effects on
the flame behavior, characteristics, flame spread rate and flame extinction. A simple apparatus was constructed to
carry out experiments extensively to validate results predicted by model.

Title of thesis : Experimental investigation of noise induced transition in thermoacoustic systems
Thermoacoustic instability has been observed in high intensity and high performance
Thesis abstract :
combustion systems. Under suitable circumstances, the fluctuating heat release rate can couple with the acoustic
field in combustion system and leads to sustained oscillations. The resulting oscillations are so intense, that they
damage the components associated with the system. The occurrence of thermoacoustic instability can be
classified in to two types: soft and hard excitations. When the oscillations start spontaneously in the combustion
chamber, the instability is said to be softly excited. In hard excitation a large amplitude disturbance has to be
imparted to initiate oscillation. In order to hard excite a combustion system the disturbance has to be above a
threshold level called triggering amplitude. This phenomenon is called as triggering. The occurrence of triggering
phenomenon has been observed to have a probabilistic nature. The probabilistic nature is attributed to the
randomness of the process that occur in the combustion system. The chances of noise triggering a system in to a
oscillatory state has been extensively studied in fields like physics, chemical and biological system. In the present
thesis, the effect of noise on the stability of a thermoacoustic system operating in a bistable region is
experimentally investigated. The thermoacoustic system chosen for investigation is a ducted non-premixed flame.
The system is excited by random fuel flow rate fluctuations which affects the system dynamics as parametric
noise. Under the influence of noise, the system undergoes transition from stable to oscillatory state. In particular,
transition is observed even when the amplitude of the noise is significantly less than the triggering amplitude of
the corresponding deterministic system. While triggering from noise of low amplitudes, phase portraits reveal that
the system evolves transiently towards an unstable periodic orbit, before eventually growing to a stable periodic
orbit. A stochastic stability map is constructed to represent the probability of the system to undergo transition. It is
also observed that the amplitude of the oscillatory state is affected by the noise level.

Title of thesis : Investigating the Effects of Spectral Energy and Temporal Fine Structure for Improved Speech
Perception Using an Acoustic Simulation Model Developed for Cochlear Implants.
Thesis abstract : Cochlear Implants (CI) are surgically implanted biomedical devices that can provide hearing to
severely deaf people by direct stimulation of the auditory nerve, electrically. Current CI speech processors do not
convey phase information, which is important for perceiving music and for hearing in noisy environments. This
thesis discusses a new acoustic simulation model for CI, that extracts the ‘envelope’ by continuous-interleaved
sampling (CIS) principle and ‘temporal fine structure’ cue (phase information) by Hilbert transform. The dominant
channels are identified from the filter bank outputs and subjected to temporal analysis. The amplitude estimates
are derived through rectification and low-pass filtering. By Hilbert transform, the temporal fine structure is
extracted through formant peaks in the signal which contributes for speech intelligibility. After band pass filtering
the speech signal, carrier signals that are specific to the band outputs, are constructed using biphasic pulses in
the extracted fine structure which has greater peaks. The filtered outputs from all the channels are subjected to
amplitude-modulation using the carrier pulses and the synthesized speech is generated by summing all the
modulated outputs. 15 phonemes are analyzed for its envelope and phase information and the recognition rates
are estimated with 15 listeners. The simulation results indicated that this model produced significant
improvements in the recognition scores of vowels and consonants. The proposed model should be helpful for
developing advanced speech processing strategies and improving the speech perception of CI users.

Title of thesis : Discrete Element Method for Impact Problems
Thesis abstract : Discrete Element Method (DEM), an explicit numerical scheme to model mechanical response
of solid and particulate media. This DEM is used to study the ballistic impact of a projectile hitting the target and
its post impact behavior. In the current study, 1-D DEM is used to obtain the depth of penetration for blunt copper
bullet impacting thick aluminium target. A new type of discrete element- a Quadrilateral element is introduced in
2-D DEM. Ballistic impact simulation of blunt and conical steel bullet impacting thin concrete target is being
carried out using Quadrilateral Discrete Element Method. Both 1-D and 2-D DEM are validated with available
results in literature.

Title of thesis : Electromechanical Response of Conducting Polymers
Thesis abstract : Polyaniline (PANI) an electronically conducting polymer, and its charge transfer complexes are
interesting engineering materials due to their unique electronic conductivity, electrochemical behavior, low raw
material cost, ease of synthesis and environmental stability in comparison with other conjugated polymers. The
main disadvantage of PANI is its limited processability. Blending of conducting polymers with insulating polymers
is a good choice to overcome the processability problem. In this study a solution-blend method is adopted to
prepare conductive polyaniline/polyvinyl alcohol (PANI/PVA) blend films at various blend ratios. Interest in
applications for polyaniline (PANI) has motivated investigators to study its electro mechanical properties, and its
use in polymer composites or blends with common polymers. The work described here looks at the
uniaxial/Biaxial deformation behavior of the conducting polymer films and the anisotropic dependency of electrical
conductivity of the blend films exposed to static and dynamic loading conditions. The relation between mechanical
strain, electrical conductivity and film microstructure is investigated on PANI/PVA blend films.

Title of thesis : Damage Estimation in Vibrating Beams from Time Domain Experimental Measurements
Thesis abstract : The problem of damage detection in beams from time domain vibration measure-ments is
investigated. A cantilever beam subjected to dynamic point loadings is considered. A measurable damage in the
form of a notched crack is introduced into the beam. Using Bayesian principles, a particle filtering algorithm
applied on the ex-perimentally measured tip accelerations is used to estimate the changes in damping and the
localized reductions in the flexural rigidity of the beam at various loca-tions. Subsequently, the size and location of
the crack is estimated using principles of fracture mechanics and particle filtering. Strategies onreducing the
associated computational costs are also discussed.

Title of thesis : Numerical analysis of effects of angle of attack, axis ratio and Reynolds number on fluid flow and
heat transfer across elliptic cylinders using parallel algorithm based immersed boundary method
Thesis abstract : Fluid flow and heat transfer characteristics of flow around slender and bluff bodies is of greater
interest as it has interesting flow behaviours as well as because of it's wide range of applications. Though the
literature on flow around circular or square cylinder is vast, many enginineering applications like flow past aircraft
wings, missiles, rotor blades require the body to be modeled as flow past an elliptic cylinder. The literature on
these kind of non-canonical problems is very limited. This study aims to unreveal the fluid flow and foced
convective heat transfer characteristics of flow around an inclined elliptic cylinder. Parameters considered in this
study are (i)axis ratio, (ii) angle of attack (iii) Reynolds number. Since this study require change in grid for a
change in axis ratio/angle of attack, an efficient Cartesian grid technique called Immersed Boundary Method
which eliminates the need of new grid is used for the simulations. A large computaional domain is ued to capture
the secondary vortex shedding behind slender elliptic cylinders. A parameter space graph is constructed to reveal
the dependence of axis ratio, angle of attack and Re on vortex shedding. Integral parametrs of fluid flow and heat
transfer are computed. Useful functional relationships are obtained for every integral parameters with respect to
axis ratio, angle of attcak and Re. An attempt is made to parallelize this solver using Message Passing Interface
(MPI) which is an efficient parallel algorithm.

Title of thesis : Estimating the rain-flow fatigue damage in wind turbine blades using polynomial chaos
Thesis abstract : Modern wind turbine blades are slender structures whose increased flexibilities have led to
unforeseen aero-elastic instabilities leading to failures. In this study, the turbine blade is modeled as a twodimensional airfoil and is subjected to random loading. The airfoil is assumed to oscillate in rotational as well as
translation degrees of freedom. The loading is assumed to be stationary and Gaussian. The fatigue damage due
to this loading is described through the rain-flow cycle counting method. An approach based on polynomial chaos
expansion is used to obtain the response of the nonlinear oscillator.

Title of thesis : NUMERICAL SIMULATION OF INCOMPRESSIBLE VISCOUS FLOW FOR INVESTIGATING
INSECT FLIGHT DYNAMICS
Thesis abstract : The present study stems from our interest in understanding the insect fluid dynamics relevant
to Flapping Micro-Air Vehicles (FMAVs). Natural flyers and swimmers, which have evolved over millions of years,
represent one of nature’s finest locomotion experiments. The insects use the flapping wings forward flight and
even for hovering also. Understanding the unsteady aerodynamics of the flapping wings of insects which results in
the saccade maneuver would be extremely valuable to designers in their attempts to create vehicles capable of
obstacle-avoidance, stealth and gust response.
A numerical study of two dimensional wing(of different crosssections) in sinusoidal plunging and pitching motion(individually and combined) was carried out to examine the
effect of flapping frequencies, plunge amplitude, phase difference between pitch and plunge motion, wing
thickness and finally location of pitching axis on its aerodynamic characteristics at low Reynolds number. Physical
parameters in terms of the instantaneous and mean values of lift, thrust coefficients and propulsive efficiency
were discussed in detail. Additionally, Lift coefficient was also calculated using analytical models.

Title of thesis : Numerical studies of turbulent fluid flow and heat transfer in a plane asymmetric diffuser
Thesis abstract : The asymmetric diffuser has many industrial and engineering applications, thus making the
study of its fluid flow and heat transfer characteristics imperative. The simulation of the flow becomes more
challenging when the flow is turbulent and it is desirable that the turbulent charateristics are predicted in a time
efficient manner. In the present study, firstly, a SUPG finite element based Navier Stokes solver for constant
density laminar/turbulent flow in 2D/3D geometry is developed and validated. It is followed by the testing of the
three popular k-epsilon models ,i.e., Standard, RNG and Realizable, for their suitability to predict the aforesaid
flow. The k-epsilon model, found most suited, is finally used to perform parametric study of flow and dimensional
parameters affecting the fluid flow and heat transfer characteristics.

Title of thesis : Numerical Study on Influence of Wall Proximity on Effectiveness of Vortex Generator in Vortex
Suppression and Heat Transfer Enhancement using Immersed Boundary Method
Thesis abstract : Many control strategies have been proposed in order to suppress vortex shedding and to
enhance heat transfer. Since the vortex dynamics and its associated flow and heat transfer characrteristics is very
much sensitive to incoming flow condition (Incoming shear, turbulence intensity etc), the effectiveness of control
methods also varies. In our study we have investigated the effectivness of vortex generators in the presence of
plane wall. Presence of wall creates boundary layer and induces shear in the flow and when the bluff body
(circular cylinder) is immersed in this highly viscous boundary layer, the vortex shedding pattern is completely
changed. As reported in the previous literatures, upstream placement of a stationary cylinder or a rotating
cylinders suppresses the vortex sheeding and reduces drag. Effectiveness of two vortex generators, namely
stationary cylinder and rotating cylinder have been investigated in the presence of plane wall at Re = 100. This
numerical study is carried out using finite difference based immersed boundary method.

Title of thesis : Identification and functional characterization of genetic variants in the dysglycemic peptide
Pancreastatin with metabolic dis-orders in an Indian population
Thesis abstract : Chromogranin A (CHGA), ubiquitously expressed in secretory cells of the neuroendocrine
system, has recently emerged as an important regulator for diverse physiological functions. Pancreastatin (PST),
a proteolytic derivative of CHGA, acts as a dysglycemic peptide by inhibiting glucose-stimulated insulin secretion.
Resequencing of pancreastatin region of CHGA in an Indian population (n=1625) revealed the occurrence of three
naturally occurring variants: C9226T causing substitution of Arg253 by Trp253, G9328A causing substitution of
Glu287 by Lys287 and G9358A causing substitution of Gly297 by Ser297. While the Glu287Lys is a novel variant
in our population, the Gly297Ser and Arg253Trp variants were reported in a European population. Interestingly,
the 297Ser variant was ~11-fold more frequent whereas the PST-253Trp variant was ~3.1-fold less frequent in our
population than the European population. The PST-287Lys and PST-297Ser peptides were more potent than the
wild-type (PST-WT) peptide in modulating pleotropic events of glucose metabolism (viz. ability to inhibit insulin
stimulated glucose uptake) and altering phosphoenol pyruvate carboxykinase-1 and glucose-6-phosphatase
promoter activities. CD spectroscopic analysis suggested that PST-287Lys and PST-297Ser peptides had
significantly higher propensities to form secondary structure (specifically, alpha helix) than the PST-WT peptide
providing a structural basis for their differential biological activities. The 297Ser allele frequency was ~1.6-fold
higher in type 2 diabetic subjects than the controls; individuals having the 297Ser allele displayed higher plasma
catecholamines and fasting blood sugar values than the carriers of 297Gly. Taken together, naturally-occurring
variations in the PST region seem to have important cardiovascular and metabolic consequences.

Title of thesis : FUNCTIONAL CHARACTERIZATION OF HUMAN GENETIC POLYMORPHISMS IN
PHYSIOLOGICAL ANTIHYPERTENSIVE PEPTIDE CATESTATIN
Thesis abstract : Essential hypertension (EH) is the most common risk factor for cardiovascular diseases with a
prevalence of nearly 27% worldwide, and it aggregates with other cardiovascular risk factors. Even though the
exact molecular mechanism for the pathogenesis is unclear, genetic studies identified several candidate genes for
EH. Chromogranin A (CHGA), ubiquitously expressed in secretory cells of the neuroendocrine system, has
recently emerged as an important regulator in cardiovascular disease states. It acts as a prohormone giving rise
to bioactive peptides such as vasostatin [CHGA1-76] and catestatin [CHGA352-372] that exhibit several
cardiovascular regulatory functions. Catestatin is a 21 amino acid peptide that acts as a ‘physiological brake’ for
catecholamine release by inhibiting the nicotinic acetylcholine receptor (nAChR) and thus important for the
regulation of catecholamine-evoked blood pressure. Two naturally occurring variants (Gly/Ser and Pro/Leu at 13th
and 19th residues) of CST display altered inhibitory potencies. However, the mechanism of differential activities of
CST variants is unclear. Here we report re-sequencing of the catestatin region of CHGA in an Indian population
(n= 1010). We detected 2 non-synonymous single nucleotide polymorphisms in this region: A9559G, causing
substitution of Gly by Ser at the 364 position of CHGA and T9570G, causing substitution of Gly by Val at the 367
position. While the Gly364Ser variant was observed in a European population (at about 2.8-fold lesser frequency),
the Gly367Val variant is a novel one in our population. Individuals having the 364Ser variant allele displayed
altered plasma levels of several metabolic traits. Electrophysiology, secretion and calcium imaging experiments
suggested that the CST variants differed in their potencies to antagonize the nAChR. Structural analyses revealed
that the catestatin variants had altered propensities to form secondary structure as compared to the wild type
peptide. Docking and molecular dynamics simulation studies also corroborated with these experimental
observations. These findings may provide mechanistic insights into understanding the genetic and molecular
causes of hypertension.

Title of thesis : Hepatic tissue engineering using human mesenchymal stem cells and nanoscaffold
Thesis abstract : Human bone marrow derived mesenchymal stem cells (MSCs), due to its unique property of
plasticity, can be differentiated and trans-differentiated into cell types of all three germinal layers. Hepatic transdifferentiation of human MSCs has been achieved successfully with various cytokines and chemicals and also by
using serum components (platelet lysate, cholestatic serum and serum from liver injury patients). In this study, we
have evaluated the hepatogenic potential of human MSCs using a novel inducer (i.e. sera obtained cardiac failure
patients, who has developed secondary jaundice). Due to high level of hepatocyte growth factor and allied
hepatogenic factors present in such sera, the process of hepatic trans-differentiation of MSCs can be more
effective. The usage of a three dimensional scaffold enhances the process of cellular proliferation and
differentiation for functional tissue regeneration strategy. Therefore, in this study, we have evaluated the hepatic
differentiation of MSCs on a PLACL-collagen nanofibrous scaffold, as a supportive hepatomimetic scaffold for
liver tissue engineering.

Title of thesis : Optimization of production of Poly (3 - hydroxybutyrate) from glycerol by Paracoccus denitrificans
Thesis abstract : Polyhydroxybutyrates (PHBs) are polyester that is synthesized by microorganism intracellularly
as carbon and as energy reservoir. They are biodegradable. They find applications in medical, agricultural and
packaging industries. Currently, the cost of production of this polymer is high and it could be reduced by using a
cheap carbon source. Glycerol is being let out as waste in biodiesel industry. Using this glycerol as a cost
effective substrate our work aims to optimize the medium components and the process parameters for increased
productivity and reduced cost of the polymer. Several mathematical and statistical techniques are available for
Medium design and optimization. In our study Plackett Burman Design (PBD) and Response Surface
Methodology (RSM) were adopted. Using the optimized medium the effect of the process variables (pH, agitation,
substrate concentration..,) for the production of PHB are studied in the 2l batch bioreactor. Using these data a
structured kinetic model is developed. This kinetic model will be used to achieve high yield and productivity
through fed batch fermentation. Maximum polymer concentration of 13.5 g/l with 73 % PHB accumulation was
obtained in batch fermentation. Maximum yield and productivity were found to be 0.546 g/g and 0.3 g/l.h
respectively. This study would pave way for advanced studies like fed batch fermentation in near future.

Title of thesis : Biochemical and Biophysical Characterization of Human Phospholipid Scramblases
Thesis abstract : Currently working towards understanding the mechanism of phospholipid translocation (PL) by
ATP independant class of PL transporters called " Scramblase". These class of proteins are known to mediate
bidirectional scrambling of PL notably phosphatidylserine (PS) across the lipid bilayer during cellular processes
such as blood coagulation, apoptosis and cell activation in reponse to elevated intracellular calcium concentration.
Since it is a calcium binding protein, understanding the calcium induced conformation changes will help in
understanding the mechanism of PL translocation. However till date there exists no molecular structure and
mechanism of PL translocation still remains elusive. Hence using various biophysical, bichemical and moelcular
biology strategies we are working towards solving the above mentioned problem.

Title of thesis : To investigate, both experimentally and computationally, the role of phase information in a visiomotor task like copying simple line diagrams.
Thesis abstract : The task of copying a line is one in which there is an inherent ambiguity. The possible input
orientations can range only from 0 to 180 degrees; whereas the same line can be copied from 0 to 360 degrees.
Thus there is a one to many mapping involved, such that each orientation given as the input can be replicated in 2
possible ways which are in opposite directions. The aim of this work is to model human experimental copying data
using a dynamic neural network. In this model the phase information from an oscillatory layer is used in order that
the network learns to copy the given line. The model can simulate both the flip behavior as well as the error plots
similar to those seen in the data from human subjects. This model can be extened to the copying of arcs and
ellipses also. To investigate the role of phase information further, a relationship between the phase information of
electroencephalograph from human subjects on being shown different orientation gratings is also studied.

Title of thesis : Electrochemical Reduction of Carbon dioxide to Useful Chemicals
Thesis abstract : The conversion of carbon dioxide to useful chemicals has been a subject of numerous
investigations, as turning CO2 into useful chemical could help reduce the level of greenhouse gas in the
atmosphere. Though a variety of methods exist for carbon dioxide conversion, electro chemical and photoelectrochemical reduction have shown to be promising venture. The product selectivity in these methods for CO2
reduction can be tuned by many variables, such as concentration of the reactants, electrode potential,
temperature, electro catalyst, and nature of the electrolyte in which the stable CO2 molecule is activated and
reduced. As far as aqueous electrolyte is concerned, KHCO3 and KCl has been preferred for reducing CO2 due
its solubility; among which the adsorption of chloride ions on the electrode surface and electron-transfer to CO2
via the Xad ? (Cl)–C bond is facilitated, in the case of KCl solution. Among the metals investigated Cu and Zn with
medium hydrogen overvoltage, offer scope for higher hydrocarbon products as it can catalyze the breaking of
carbon–oxygen bond in CO2, and also allow CO to desorb. In this work, the Cu and Zn electrodes were
investigated for CO2 reduction in two different electrolytes and the effect of electrode potential, electrolyte
concentration and selectivity of the products formed are studied.

Title of thesis : Development of Palladium Structures for Fuel Cells
Thesis abstract : Fuel cells are one of the key enabling technologies for future economy thereby providing
power in stationary and portable power applications. Reduction of oxygen (ORR) is a key electrochemical
reaction, and an improved understanding of its mechanism and the development of more efficient electro catalysts
underlie much of fuel cell research. An ambitious approach towards improving cathode electro catalysts is to
completely remove Pt and replace it with less expensive materials while maintaining the catalytic activity. As an
alternative to platinum, palladium has been the focus of considerable attention in fuel cell research due to the
relatively abundant and less expensive resource. Palladium-based catalysts in nanoparticle form are seen as
ideal electro catalysts for oxygen reduction reaction due to their increased activity, surface area and improved
methanol tolerance in the case of direct methanol fuel cells. The size and structural morphology of Pd nano
particles are known to have significant effect on promoting the ORR and well controlled nano structures are
therefore essential for achieving efficient catalysts for fuel cells. Pd catalysts were prepared from chloride
precursors in acid solutions by cyclic and constant voltage deposition techniques directly on electrochemically
treated carbon-based substrates (like Vulcan XC-72R, Carbon nanotubes, Graphene etc.), which are widely used
as support material in fuel cells. The effects of electrochemical treatment and carbon loading were studied in
relation to the catalytic activity for oxygen reduction reaction in an acidic electrolyte. The catalysts were
characterized by scanning electron microscopy to study the morphology and structure of the nanoparticles.
Deposition by cyclic voltammetry and constant voltage techniques displayed a dendritic and flower like
morphology of Pd. The results indicated that controlled insertion of defects on the carbon during electrochemical
treatment favored a good Pd deposition, metal-support interaction and improved the hydrophilicity of the surface
with enhanced catalytic activity towards oxygen reduction.

Title of thesis : Approximate dynamic programming based control of distributed parameter system involving
hyperbolic PDE
Thesis abstract : Approximate dynamic programming (ADP) is a model based control technique suitable for
nonlinear models. Application of ADP to distributed parameter systems (DPS) which are described by partial
differential equations is a computationally intensive task. This problem is addressed in literature by the use of
reduced order models which capture the essential dynamics of the system. Order reduction of DPS described by
hyperbolic PDEs is a difficult task as such systems exhibit modes of nearly equal energy. In this thesis we
propose a methodology to obtain reduced order model for hyperbolic PDEs using Method of characteristics. The
focus of thesis is thus ADP based control of systems described by hyperbolic PDEs using reduced order models
from Method of characteristics (MOC). Typical examples from chemical engineering systems involving one, two
and three characteristics are studied. The proposed method is able to reduce the order of hyperbolic PDE
significantly and the use of this reduced order model in ADP based setup shows several advantages in both
performance and computational load.

Title of thesis : Measurement selection for optimal process operation
Thesis abstract : Sensor Network Design: The fundamental problem in optimal sensor network design is
choosing a set of important or strategic process variables to be measured. An optimization formulation for sensor
network design that relates process economics and data reconciliation is proposed. To address this, an economic
quantity is defined to quantify the loss of operational profit caused due to measurement uncertainty. The resulting
analytical expression that quantifies the loss is shown to be the sum of weighted error variances of the reconciled
estimates obtained from reconciliation. The final formulation is a mixed integer cone program that can be solved
to obtain a globally optimal sensor network. The effect of the process economics, capital cost, and marginal utility
of additional sensors is illustrated using case studies. Economic operating point selection. This paper discusses
the minimum backed o operating point selection problem based on process economics. In this work, we consider
the case where the nominal operating point is not completely constrained, i.e., there are some unconstrained
degrees of freedom or manipulations available. In this regard, we propose a stochastic formulation that ensures
feasible dynamic operating region within the prescribed condence limit. Furthermore, the formulation also finds
a suitable multivariable controller to achieve economic benets. The problem is nonlinear and non-convex and
hence an iterative solution procedure is proposed such that at each step in the iteration, a convex problem is
solved. Finally, the approach is illustrated using an evaporation process.

Title of thesis : Distributed model predictive control of water supply networks
Thesis abstract : Optimal operation of urban water supply networks (WSNs) is based on optimizing one or more
performance metrics while meeting consumer demands and satisfying supply side and storage constraints. This
can be achieved by implementing advanced control schemes such as model predictive control (MPC) that works
on the simulation – optimization framework. Given the fact that urban WSNs are very large scale complex
systems with high interactions, obtaining an optimal control strategy with a centralized MPC requires tremendous
computational effort and is time consuming. In this work, a distributed model predictive control (DMPC) scheme
for WSNs is proposed. WSNs are partitioned into sub-networks and a local MPC is deployed to provide control
strategies for each sub-network. Local MPCs use serial coordination scheme to cooperate with other agents in the
decision making process. With the alarming decrease in fresh water supplies, the primary focus of control
strategies should be to conserve water. A novel control strategy that can handle both water sufficient and deficient
cases is proposed for WSNs with storage facilities.

Title of thesis : High Efficiency , High Temperature PEM fuel cell power unit, auto-thermally integrated with an
ethanol reformer.
Thesis abstract : The Fuel Cells are the energy devices for the future. There most widely used fuel cells are PEM
(protone exchange membrane) fuel cells due to their various advantages in operatability and high energy density.
They are mainly of two types high temperature(HT) and low temperature(LT) PEM fuel cells. The main fuel for the
fuel cells is hydrogen gas. But due to almost nil hydrogen in our atmosphere and no present distribution and large
scale production system, hydrocarbons are mainly looked into for producing hydrogen for fuel cells. Out of all
hydrocarbons, ethanol is best suited for the job, and is highly researched for hydrogen production for fuel cells.
My project is developing an ethanol based integrated, auto-thermal reformer system for HT-PEMFC, which has
certain advantages over LT-PEMFC. This high efficiency system along with electric output produces high
temperature flue gases as well. These flue gases have been used to produce further electric energy by integrating
this system to secondary systems of LT-PEMFC ethanol reformer system and also with Combined Cycle Gas
Turbine(CCGT System) and Steam Power Cycle for high overall efficiency. Optimization studies have been
carried out for all the integrated systems to find out the best operating conditions for the system.

Title of thesis : Synthesis and Biophysical Study of 1-N-Alkanamido-, Sulfonamido- & Guanidinoacetamido
Sugars as N-Glycoprotein Linkage Region Analogs
Thesis abstract : abstract Glycan chains of glycoproteins serve not only as recognition determinants but also
influence protein folding. Elucidation of the molecular basis of their biological roles is a challenging problem in
structural glycobiology. The linkage region constituents, 2-acetamido-2-deoxy-?-D-glucopyranose (GlcNAc) and
L-asparagine (Asn), are conserved in all eukaryotic N-glycoproteins. Elucidation of the conformation of the Nglycoprotein linkage region and the molecular basis of intramolecular glycan-protein interactions is of fundamental
importance considering that motion of the GlcNAc-Asn linkage can profoundly influence the presentation of the
glycan chains on the cell/protein surface. As part of a major program aimed at understanding the structural
significance of the constituents of the conserved N-glycoprotein linkage region, our laboratory demonstrated for
the first time the effect of structural variation in the linkage region sugar and its aglycon moiety, among several
N-(?-D-glycopyranosyl)alkanamides, on the N-glycosidic torsion, fN (O5–C1–N1–C1’). This study showed that fN
is influenced to a larger extent by the structural variation in sugar part than that of the aglycon moiety. As part of
above mentioned program, several novel mono- as well as disaccharide alkanamides have been designed as
models and analogs of the linkage region of
N-glycoproteins, by varying the sugar as well as the
aglycon group, and synthesized, during the present study, successfully in reasonable yields. Neutron diffraction
analysis of N-(?-D-glycopyranosyl)alkanamides has enabled the accurate determination of hydrogen atom
positions. This study has unequivocally confirmed our earlier finding on the occurrence of antiparallel double
pillared bifurcated hydrogen bond in the case of model compound GlcNAc?NHAc and its absence in
GlcNAc?NHPr. The correct localization of hydrogen atoms in neutron crystal structures has unraveled the
occurrence of hydrophobic H???H contacts. These structures will be of interest for testing and improving force
fields in order to develop better tools for the modeling of N-glycoproteins. In order to understand the influence of
protection on molecular conformation and packing, three fully acteylated GlcNAc alkanamides have been
synthesized starting from the per-O-acetylated GlcNAc azide and their crystal structures have been solved.
Comparative analysis of these structures with those of free sugar amides reported earlier showed that
conformation of the amido aglycon moiety is not altered significantly by the masking of hydroxyl groups in the form
of acetates. The bifurcated antiparallel pattern involving N–H???O and C–H???O hydrogen bonds, a hallmark of
the N-glycoprotein models GlcNAc?NHAc and GlcNAc?Asn, is absent in all of the fully protected title alkanamides.
X-ray crystallographic analysis of alkanamides of pentopyranoses derived from ribose and arabinose revealed
that of fN (O5–C1–N1–C1’) value for Rib?NHAc varies upto ~16° as compared to Xyl?NHAc. Replacement of
carboxamide with the much more stable sulfonamide group is a well-known concept in medicinal chemistry.
Several sugar sulfonamides, which are very interesting glycosylasparagine mimetics, have been synthesized in
good yields to explore the effect of bio-isosteric replacement of carboxamide group by sulfonamide on the Nglycosidic torsion fN as well as molecular assembly. Among all the compounds synthesized, crystal structures of
eight sulfonamido derivatives have been solved. X-ray crystallographic investigations of synthesized sulfonamides
revealed several interesting features. The N-glycosidic torsion angle fN varies from a value of -73.5° for molecule
A of Man?NHSO2CH3 to a value of -97.0° for GlcNAc?NHSO2CH3. Comparison of these values with the fN
value of GlcNAc?NHAc showed that torsion angle fN (O5-C1-N1-S1) does not vary significantly by changing the
carboxamido group to sulfonamido moiety. The b-glucosyl linkage to the guanidine group of arginine (Arg) is
found in amylogenin, a glycoprotein from sweet corn. Such linkage is a rare example of
N-glycosyl bond.
Design and synthesis of mimetics of the unusual N-glycosidic linkage (Glc?Arg) with a spacer between the
glycosyl residue and the guanidine moiety was done by the reaction of appropriately protected sugar unit
containing a free amino group with suitably functionalized bis-Boc-thiourea. Two types of spacers, acetamido and
triazole moieties were chosen. Synthesis of N-glycosylarginine with an amido linker was also achieved during the
present study.

Title of thesis : “Platinum-supported Mesoporous Carbon as Electrocatalysts for DMFCs”.
Thesis abstract : Architectural modulations in solid systems have been a research fantasy in recent years, ever
since; the Mobil group came up with mesoporous silicates in the early 90s using micellar templates. Template
assisted synthesis of porous materials has seen considerable developments in the last 20 years. In fact, this
area has become a continuing endeavor in material science research, that new mesoporous materials are
designed and prepared at regular intervals exploiting all kinds of micelles and also other possible synthetic
strategies. Among the various possible systems, silicates and carbon materials have attracted considerable
attention in recent years due to the possibility of exploiting them for various applications including catalysis. The
biggest scientific challenge in the 21th century is to develop a green chemical process and new alternative energy
sources that can replace the fossil fuels. In this regard, the ultimate goal of our research is focused to synthesize
nanoporous materials such as mesoporous silicas, carbons, and Nitrogen containing carbon materials that can be
used for advanced applications in the production of alternative energy sources and in the green chemical
processes.
This present work therefore attempts to highlight some of the salient aspects on these materials as
follows: (i) The possible synthesis strategies for these materials and the logic and science behind the procedures
adopted. (ii) The physico-chemical characterization of these materials and the generalities that is possible. (iii)
Applications of Pt nanoparticles supported mesoporous carbons in DMFCs.

Title of thesis : MODELS & ANALOGS OF N-GLYCOPROTEIN
NEOGLYCOCONJUGATES: SYNTHESIS AND BIOPHYSICAL STUDY
LINKAGE
REGION
AND
Thesis abstract : Carbohydrates (glycans) covalently linked to peptide/protein or lipid form glycoconjugates such
as glycoproteins and glycolipids, respectively. Understanding the structure-function relationship of carbohydrate
mediated interactions with protein/lipid has been a challenging problem in structural glycobiology. The major goals
of the present study are synthesis and biophysical study of models and analogs of N-glycoprotein linkage region
and neoglycoconjugates. The linkage region constituents of eukaryotic N-glycoproteins consist of
2-deoxy-2-acetamido-?-D-glucopyranose (GlcNAc) as the linkage sugar and L-asparagine (Asn) as the linkage
amino acid. Elucidation of the structure and conformation of the linkage region of glycoproteins is of fundamental
importance since the dynamics of the GlcNAc-Asn linkage can influence the presentation of the glycan chain on
the cell surface. The
X-ray crystallographic investigation of glycoproteins is complicated due to the
conformational flexibility of glycan portion. Use of model and analog compounds would be a valuable approach to
understand the effect of structural variations on the linkage region conformation. To this end, several glycosyl
amides have been designed and synthesized as model and analogs of the N-glycoprotein linkage region. To
understand the role of
C2-acetamide group in controlling the N-glycosidic torsion fN & ?2, newer
N-(3-deoxy-3-acetamido-b-D-glycopyranosyl)alkanamides analogs have been synthesized. The crystal structures
of newer C3-acetamido analogs Glc3NAc?NHAc and Glc3NAc?NHPr solved during present study were compared
with those of
C2-acetamido model (GlcNAc?NHAc) and analog (GlcNAc?NHPr) reported earlier. This
study showed that absence of the C2-acetamido group increases rotational freedom around C1–N1 and C2’-C3’
bonds which leads to large variation in the
N-glycosidic torsion values fN and c2. To understand the effect of
carboxylic group on N-glycosidic torsion as well as molecular packing, uronic acid alkanamides and 1-(?-Dglycuronopyranosyl)-4-phenyl-[1,2,3]-triazoles have been synthesized. The crystal structure of the GalUA?NHAc
solved during present study was compared with those reported for N-(?-D-galactopyranosyl)alkanamides. It
revealed that change of the C6 hydroxylmethyl group to carboxylic acid had limited impact on glycosidic torsion,
fN. Disaccharide alkanamide crystal structures solved during present study were compared with the crystal
structure of GlcNAc and Glc alkanamides. It showed that N-glycosidic torsions fN and c2 are influenced by the
presence/absence of C2-acetamido group as well as molecular packing. In the case of GlcNAc alkanamides, the
influence of molecular packing on linkage region conformation is relatively less. Thus the steric effect of
C2-acetamido group is controlling the N-glycosidic torsion values leading to negligible variation in N-glycosidic
torsion values fN and c2. In the case of disaccharide crystal structures, due to the intensive network of hydrogen
bonding, molecular packing becomes a dominant force for controlling conformation which leads to noticeable
variation in fN values and large variation in c2. Sugar-based surfactants are (glycolipids) are widely used as
detergents, personal care products, food, pharmaceuticals, agrochemicals and explosives. These are also used
as low-molecular-mass gelators which have attracted attention due to their impact in the field of molecular
self–assembly, smart materials and controlled chemical release. In the present work, various sugar derived
glycolipids with thiourea, urea and amide linkages have been designed and synthesized. Gelation study showed
that thiourea- and urea-linked glycolipids have formed hydrogel. Critical gelation concentration (CGC) for these
hyrogels is less than 1wt % which makes these compounds classified as ‘‘super-gelators”. Morphological study
of the thiourea- and urea-linked glycolipids showed that depending on the sugar head group and alkyl chain
length they have self-assembled in water and forming 3D fiber network or ribbons of various sizes (nm).
Interaction of carbohydrates with lectins is an important event for wide range of normal biological processes such
as immune function and fertilization. Hampering this multivalent interaction is important for blocking or influencing
biological processes, such as viral or bacterial infections or even cancer metastasis. In the present work,
pentarerythritol-based per-O-acetylated N-glycoconjugates with thiourea linkage have been synthesized. Their deO-acetylated derivatives will be useful for the study of carbohydrate-protein interactions.

Title of thesis : Stereoselective Approaches to Substituted Tetrahydropyrans, Morpholines and Oxazepanes
Thesis abstract : Amongst cyclic ethers, tetrahydropyran ring is the most common structural motif present in
wide variety of natural products, which exhibit important biological properties. As a result, a number of methods
have been developed for the stereoselective construction of these tetrahydropyran ring systems.1 Among these
intramolecular oxa conjugate addition to an enoate has been extensively used in the synthesis of natural
products. A general strategy was developed for the stereoselective synthesis of 2,6-disubstituted
tetrahydropyrans, employing a Tandem nucleophilic addition-oxa-Michael sequence to aldehydes which contains
appropriate Michael acceptor (Scheme 1).2 Scheme 1 Substituted morpholines and oxazepanes are present in
vast number of therapeutically and biologically active compounds.3 Also the C-substituted morpholines are used
as chiral agents in asymmetric synthesis, due to which there is increase in new methods for the synthesis of Csubstituted morpholines. A general and concise strategy was developed for the stereoselective synthesis of
diversely substituted morpholines, based on reductive etherification strategy (Scheme 2).4 The developed method
was also utilized in the synthesis of natural products Chelonin A and Chelonin C. Scheme 2 The Reductive
etherification strategy was also extended for the stereoselective synthesis of substituted oxazepanes.

Title of thesis : Control of VOC emission from manufacturing and application processes of surface coatings
Thesis abstract : The main objective of the study is to develop a biological VOC treatment technology for paint
manufacturing and application processes. Volatile Organic Compounds or commonly known as VOCs are
compounds which easily vaporizes in normal room temperature because of their high vapor pressure and low
solubility. VOC emission propels the process of ground level ozone formation in an urban atmosphere. Some
VOCs like Toluene have proven mutagenic/ carcinogenic effect on human. Paint manufacturing and application
facilities vent out a significant amount of VOCs in the atmosphere. Present abatement techniques such as
adsorption or absorption merely shift the pollutant from air-phase to other matrices rather than actually destroying
it. Incineration though viable for high-calorific value VOCs such as those emitted from petroleum refineries, is
often not economically feasible for low-concentration and high-flow rates associated with many VOC emitting
industries such as surface coating industry. Though industrial emission of Volatile Organic compounds cause
significant effect on the ambient environment. My thesis work includes study the biodegradation kinetics of
common VOCS emitted from paint manufacturing and application facilities such as Methyl Ethyl Ketone (MEK),
Methyl Iso-butyl ketone (MIBK), Toluene, Ethylbenzene and o-Xylene. The study started with acclimatization of
open-mixed aerobic bacterial culture. This acclimatized culture was used for the biodegradation of the VOCs
already mentioned. The study emphasizes on the biodegradation kinetics of these compounds in presence of
each other rather than only as single compound. Bio-kinetic models such as Monod Inhibition models were used
to evaluate the biokinetic parameters of the biodegradation of these five compounds. Further mathematical model
was developed to describe the mixed substrate biodegradation pattern of these compounds. Two type of bioreactors were designed one Bio-trickling filter (BTF) and one Rotating Biological Contactor (RBC), and the
biodegradation efficiency was compared for these two reactors. The detailed biological study about the nature of
microbes which populate the reactors at various stages of the study was also studied.

About me :
I am an environmental engineer with bio-technology back-ground. Anthropogenic environmental pollution with
simultaneous industrial growth is a challenge to my generation and newer economically viable treatment
technologies are the need of the hour. I want to see myself in R&D activites in future through which I can properly
utilize the knowledge and skills I gained thus far in my career. I feel a lot is talked about and taught about in
environmental engineering while implementation part is clearly lacking. Be it safe disposal of e-waste or municipal
waste or passing on clean air, energy and drinking water resources to future generation a lot has to be done.
Environmental pollution problems being of widely diverse in nature it needs a wide variety of skill sets to solve
any particular problem. I would love to work in group projects on contemporary environmental problem,with
people from different back-ground as that gives different perspectives to see the same problem. Desalination of
sea-water and pre-treatment of water before RO inlet is a topic close to my heart as I believe Sun will be our
future energy source and Sea our future drinking water source.

Title of thesis : Experimental and Numerical Study in Behaviour of Single and Group Pile in Sloping Ground
Thesis abstract : Behavior of pile foundation in slope is a real time issue. Structures such as offshore platform,
transmission towers, high ways and various industrial units are constructed in the slope supported by pile
foundation; where the piles are subjected to load from super structure, earth pressure on retaining wall, wind load,
wave and current actions in case of offshore structures. The behaviour of pile under lateral load in sloping
ground is different from horizontal ground. The aim of this paper is to study the behaviour of single and group pile
founded in sloping ground experimentally and numerically (PLAXIS -3D). Model tests were performed in the
laboratory by using instrumented pile embedded in clay by varying the slope (1V:3H, 1V:2.5H and 1V:2H). The
experimental study also involves the various position of pile (crest, 1R and 2R; where R is the stiffness factor)
where the lateral load is applied towards the slope under two different shear strengths (30kPa and 50kPa). The
experimental and numerical results were compared.

Title of thesis : Determining current state of a bridge using quasi static loading and strain measurement
Thesis abstract : One is interested in determining the current state of a bridge for a variety of reasons like to
ascertain whether the axle load and/or the speed of the vehicle can be increased over the bridge. Thus
determining the current state of the bridge involves not only determining whether the bridge is damaged but also
to find material stiffness degradations as well as the condition of the support. A methodology for finding the
material stiffness and the possibility of bearing seizure from strain measurements at preferred predetermined
locations under slow moving normal vehicle loads in simply supported bridge decks after just one analysis is
proposed. Strain gauges are to be pasted on the bridge at locations where the longitudinal bending stresses are
alone present. Using the fact that, in a statically determinate, homogeneous bridge the bending stresses are
independent of the material model, the linear elastic material parameters, namely Young’s modulus and shear
modulus are determined after just one analysis. The bearing seizure is found by looking for reversal of curvature
at a section close to the support as the vehicle moves over the bridge. The current state of a prestressed ultra
high performance concrete(UHPC) bridge instrumented and tested before the above methodology was available
is determined using the proposed algorithm. The efficacy of the algorithm to detect damage is also studied.

Title of thesis : Probabilistic assessment of strength deterioration of reinforced concrete bridge deck due to
corrosion of rebar
Thesis abstract : Reinforced concrete (RC) bridges constructed in the coastal areas and marine environment
deteriorate with time due to the ingress of moisture with chloride ions. The cross-sectional areas of the steel bars
reduce due to corrosion, which leads to reduction in the flexural capacity of the deck of a bridge. The present
study describes a probabilistic approach for assessing the deterioration in the capacity for a typical girder-andslab road bridge deck, considering chloride induced corrosion of plain mild steel (MS) and cold twisted deformed
(CTD) bars that were traditionally used in bridges. The rate of corrosion of the bars is one of the important
parameters to predict the service-life of a corroding structure. It is necessary to determine the rates of corrosion of
such rebars, which can be substantially different from those of the bars presently used. An experimental program
was undertaken to determine the rates of corrosion of MS and CTD rebars, under standard laboratory
environmental conditions. The Linear Polarization Resistance (LPR) technique with a 3-electrode corrosion cell
setup was used to measure the corrosion rates. Next, the modelling of chloride induced corrosion of bars for
estimating the flexural capacity of a girder of the bridge deck was done. Finally, the time-variant flexural capacity
of the girder using Monte Carlo simulations is described.

Title of thesis : Ultimate Strength of Isogrid Stiffened Composite Cylindrical Shells
Thesis abstract : Structural efficiency is a primary concern in aerospace and aircraft industries. The development
of light weight and highly efficient structural components is desirable for space and launch vehicles. Due to high
strength to weight ratio and high stiffness to weight ratio CFRP stiffened shell structures have been used to fulfill
these applications. Shells are stiffened along longitudinal, circumferential or in both directions on inner or outer
surfaces. The concept that is found most promising is isogrid pattern of stiffening the shells and the grid members
are arranged in an equilateral triangle pattern. Hence isogrid stiffened CFRP composite cylindrical shell structures
are used in launch vehicle payload rings, interstage rings, engine ducting, and space station modules and are
subjected to axial loads and it is important to study the buckling and post buckling behavior for practical
applications.

Title of thesis : DESIGN AND ANALYSIS OF PROVABLY SECURE PUBLIC KEY CRYPTOSYSTEMS
Thesis abstract : The basic problem of cryptography can be considered to be the issue of secure communication
between two parties using a communication medium which is not under the exclusive control of these two parties.
Such a medium is called a public channel, highlighting the fact that the information flowing across this channel is
publicly accessible. An alternate view of cryptography is the task of building an implicit secure communication
channel over an explicitly given insecure public channel. In spite of the importance of the problem, the security of
a cyptographic protocol / primitive was established in an ad-hoc or unscientific fashion in the earlier days of
cryptography. In fact, even as late as early 70's, we did not have a formal way to specify on security requirements
and no specific attack model was available either. Over the years, "Provable Security" has become an important
research area in modern cryptography. We have provided new / improvement / efficient / cryptanalysis of
cryptographic primitives - encryption, signature, signcryption and their variants in the public key setting. We have
given affirmative answers to several significant open problems, provides first solutions to newly formulated
primitives and refines existing security models of few public key primitives.

Title of thesis : STUDIES ON SOME ENCRYPTION, SIGNATURE AND SIGNCRYPTION SCHEMES
Thesis abstract : Public Key Cryptography can be studied in various settings: PKI based, Identity Based and
Certificateless to name a few. This thesis is a consolidation of research work done with respect to several
cryptographic primitives with respect to one or more of the above settings. The research work reported in this
thesis is on provably secure public key cryptosystems and their variants. The nature of work done may be
designing new cryptographic primitives according to the sheer need for practical security and considering new
types of attack models, modeling them mathematically and providing counter measures for improving the security
of systems to with stand the new type of attacks, cryptanalysis of existing primitives, fixing the existing scheme,
efficiency improvement and proposing new security models. More specifically the work done in this thesis are as
follows: • We have initiated a research to counter the attacks due to malwares such as RAM scrapers and
extended the existing security model to capture the effect of RAM scrapers precisely. We refer this extension as
adaptive chosen ciphertext attack with glass box decryption. After formally introducing the new kind of
attack/threat, we show the vulnerability of few existing schemes in the newly proposed model and propose new
secure schemes. • We have formally argued that the security claim made for one of the stateful identity based
encryption schemes is impossible to achieve. We have provided a new security proof for the scheme, assuming
the hardness of the Gap Bilinear Diffie Hellman (GBDH) problem. • We have proposed two new stateful public
key encryption schemes with ciphertext verifiability. Our schemes offer more compact ciphertext when compared
to all existing stateful public key encryption schemes with ciphertext verifiability. • A conditional proxy reencryption (C-PRE) scheme is one in which the proxy can transform the ciphertext generated with the delegator’s
public key, associated with a condition set by the delegator into ciphertext under delegatee’s public key, (so that
the delegatee can decrypt it) only if the proxy has the re-encryption key for that condition. There are few C-PRE
schemes in the literature. We have proposed a more efficient C-PRE scheme which uses substantially less
number of bilinear pairings when compared to the existing ones and proved the security of the scheme in the
random oracle model. • We have proposed two novel RSA based adaptive chosen ciphertext secure (CCA2)
certificateless encryption schemes. The new schemes are efficient when compared to other existing certificateless
encryption schemes that are based on the costly bilinear pairing operation and are quite comparable with the
certificateless encryption scheme based on multiplicative groups (without bilinear pairing) and the only existing
RSA based CPA secure certificateless encryption scheme. We consider a slightly stronger security model than
the ones considered in the literature to prove the security of our schemes. • A Self Proxy Signature (SPS) is a
type of proxy signature wherein, the original signer delegates the signing rights to himself (Self Delegation), there
by generating temporary public and private key pairs for himself. Using a SPS the signer can prevent the
exposure of his permanent private key from repeated use in an insecure environment. We have proposed the first
identity based self proxy signature scheme. We have given a generic scheme and a concrete instance in the
identity based setting. We have defined the appropriate security model for the same and proved both the generic
and concrete schemes in the defined security model. • Group Inside Signature (GIS) is a signature scheme that
allows the signer to designate his signature to be verified by a group of people, so that members other than the
designated group cannot verify the signature. In Broadcast Group Oriented Signature (BGOS), a user from one
group can designate his signature to be verified by members of another group. An Adaptable Designated Group
Signature (ADGS), is one in which a user can designate his signature to be verified by a selected set of members
who are from different groups. We have cryptanalyzed few schemes on all the above mentioned areas and have
proposed a new identity based ADGS scheme and proved its security in the random oracle model. • Confidential
communication with sender authentication is efficiently achieved by using a single cryptographic primitive called
signcryption. In Threshold Signcryption scheme, only if “t” out of “n” users in the sender group (where t < n)
combine together, signcryption can be performed. When this constraint is posed on the receiving end (i.e “t” out
of “n” users in the receiving group combine together), the scheme is called as Threshold Unsigncryption. We
have analyzed the security of all existing threshold signcryption schemes, identity based threshold signcryption
schemes and identity based threshold unsigncryption schemes. We have proposed new threshold signcryption
schemes both in PKI and identity based setting and an identity based threshold unsigncryption scheme, and
prove the security of the schemes in the random oracle model. • It is often required that multiple senders have to
signcrypt a single message to a certain receiver. Obviously, it is inefficient to signcrypt the messages sepa rately.
The concept of multi-signcryption is similar to that of multi-signatures with the added property - confidentiality. We
show the weakness of the only existing multi-signcryption scheme and provide a fix for the scheme and formally
prove the security of the fixed scheme.

About me :
I started my career as a lecturer in the Computer Science and Engineering Department of The PET Engineering
College in India, which is affiliated to Anna University. I worked there for three years and six months. During my
service there, I taught basic engineering subjects to undergraduate students. More specifically, I taught Data
Structure, Computer Algorithms, Programming Languages C and C++, Object Oriented Programming, Compiler
Design, Computer Architecture, Unix System Programming and Digital Electronics. At first I felt hard to deal with
new subjects and face students immediately after graduation. I had to spent most of the time preparing class
notes and presentations. After some time I found it interesting to do this and got fully indulged into teaching. My
knowledge on these subjects improved due to my preparation and the valuable doubts rose by students in the
class. My post graduation was at this period and my knowledge has improved a lot due to my teaching experience
and was able to excel with flying colors in my post graduation. I used to present to my fellow lecturers new areas,
which I read, from the Internet or from new textbooks. It was very much appreciated by the head of the
department. I handled several undergraduate laboratory courses and projects during this period.
Next, I joined the Jimma University, in Ethiopia. I delivered my service as lecturer there for one year and six
months. There too, I was able to impart knowledge to the undergraduate students on subjects like Data Structure,
Computer Algorithms, Programming Languages C and C++, Object Oriented Programming and Computer
Architecture. Every semester I received good feedback from the head of the department. It was during my stay
there, my passion towards research started. I started reading research articles and journals at this time and I
started the quest.
Currently I am a PhD scholar in IIT Madras. I have acted as teaching assistant for a variety of classes including
Theoretical Computer Science, Cryptography Theory and Practice, Design and Analysis of Algorithms & Data
Structures. I have also secured the “BEST Teaching Assistant Award” during this period. As my research is on
public key cryptography, I wish to teach cryptography in the advanced level. There were lots of students from
other institutes who come for internship to our institution. I have acted as a mentor to them and had frequented
discussions with them. This helped me share lot of ideas and thoughts with them. Often I offer tutorials to the new
comers to introduce the state of the art and enlighten young brains.

Title of thesis : Energy Efficient Shared Data Synchronization
Thesis abstract : Shared data synchronization is at the heart of the multi-core revolution since it is essential for
writing concurrent programs. Ideally, a synchronization technique should be able to fully exploit the available
cores, leading to improved performance. However, with the growing demand for energy-efficient systems, it also
needs to work within the energy and power budget of the system. In this thesis, various shared data
synchronization techniques are compared and characterized. Further, enery-efficient alternatives are proposed.

Applications to Case Based Reasoning Systems
Thesis abstract : The quality of the cases maintained in a case base has a direct influence on the quality of the
proposed solutions. The presence of cases that do not conform to the similarity hypothesis decreases the
alignment of the case base and often degrades the performance of a CBR system. It is therefore important to find
out the suitability of each case for the application of CBR and associate a solution with a certain degree of
confidence. Feature weighting is another important aspect that determines the success of a system, as the
presence of irrelevant and redundant attributes also results in incorrect solutions. We explore these problems in
conjunction with a real-world CBR application called InfoChrom. It is used to predict the values of several soil
nutrients based on features extracted from a chromatogram image of a soil sample. We propose novel feature
weighting techniques based on alignment, as well as a new alignment and confidence measure as potential
solutions. The hypotheses are evaluated on UCI datasets and the case base of Infochrom and show promising
results. We have also looked into the aspects of visualization of high-dimensional spaces for effective multivariate data analysis using parallel coordinates.

Title of thesis : ONU POWER SAVING MECHANISMS IN PASSIVE OPTICAL NETWORKS
Thesis abstract : Power efficiency will be one of the primary factors dictating the choice of future network
deployments. Passive Optical Networks (PON) in general consume less power and are well positioned to be the
technology of choice for future access networks. In a PON, the Optical Network Units (ONU), that provide the
interface between the end user and the optical line terminal (OLT), consume a substantial amount of power. In
particular, large buffer capacity typically in the order of megabytes (MB) is required for holding the upstream
packets at the ONU. In this thesis,we propose three schemes viz. Zero Buffers (ZB),Node Proportional Buffers
(NB) and Rate Proportional Buffers (RB). They impose aggressive buffer capacity constraints on the ONU to save
power. With this, the packets will be buffered predominantly at the EN. By buffering at the EN, an increase in the
end to end packet delay is expected. The network performance of the proposed schemes is studied through a
discrete-event simulation model. The simulation results indicate that despite buffer size reduction, an acceptable
network performance can be achieved.

Title of thesis : Design and Implementation of a Service Abstraction-Based Operating System with a Case Study
of Linux Kernel
Thesis abstract : Traditional procedural operating system (OS) kernels sacrifice maintainability and
understandability for optimum performance. Though object oriented (OO) kernels can address these problems
upto a certain extent, they lack the layered approach of services and service compositions. We present a new
kernel design model Dhara, that raises the level of abstraction from objects and procedures to services. The
service model of Dhara is richer in abstractions than current web service model and paves the way for building a
new distributed OS kernel. Dhara conceives an OS as being constructed by multiple stacks of services containing
several layers of abstracted services. A key research challenge we envisage in building such model is automatic
service compositions of kernel services which can provide desired QoS. A kernel built using Dhara can easily be
customized using composed services to derive optimal performance for different applications such as databases.
A prototype is developed using Linux kernel as a case study by applying the design concepts of Dhara. We show
that overhead of implementation of Dhara is 5% to 15%, which is reasonable, considering the advantages of new
design and increased capacity of the hardware in recent times.

Title of thesis : Degree Sequence and Sets - Algorithms and Combinatorial aspects
Thesis abstract : Representation of graphs is a fundamental problem in graph theory. Adjacency matrix/list is
one way of representing graphs using O(|V|2) space. Similarly,there is another alternative way of representing
them through their degree sequence at the cost of loosing uniqueness which takes O(|V|log|V|) space. Degree
sequence d=<d1,d2,….,dn> of a graph G(V,E),where V={v1,v2,..,vn}, is defined as a sequence such that for all i
?[n], deg(vi)=di. Similarly, if we collect distinct terms in the degree sequence we get the corresponding Degree
set. There exists characterizations of different graphs, viz. simple graphs, trees, connected graphs, bipartite
graphs, digraphs etc., in terms of degree sequence and sets. For DAGs this problem is NP-complete. All
characterizations mentioned above are of potential nature so we are trying to forcibly characterize DAGs in
degree sequence world. We are also exploring similar results in degree set domain.

Title of thesis : Study of Scheduling Algorithms in IEEE 802.16e and 3GPP Release - 10 networks
Thesis abstract : Resource allocation problem is a widely researched area in wireless broadband networks given
the complexity of the problem and the growing popularity of 4G technologies. The first part of the work is
regarding the performance of some well known scheduling algorithms such as PF (Proportional Fairness),
MLWDF (Modified Longest Weighted Delay First), Exponential rule and its variants with respect to WiMAX or
IEEE 802.16e networks. A new scheduling algorithm based on the exponential rule has been proposed and
compared to the previously mentioned algorithms. The study shows that hierarchical schedulers i.e, the ones
which use different scheduling rules for different traffic types perform better in a WiMAX scenario. Scheduling
algortihms like MLWDF and exponential rule for waiting times are more effective in allocating resources to realtime applications and proportional fairness, proposed variation of exponential rule work effectively for non-real
time applications. The simulation for this part of the work has been done on OPNET Modeler. The second part of
the study proposes a scheduling algorithm for streaming video applications which allocate resources based on the
QoE (Quality of Experience) of the users. This part of the work has been done on NS-3 modeler over an LTE
network.

as an AI Search and Planning & Scheduling problem. The work focuses on modeling the convoy movement
problem using PDDL and attempting a solution using existing planning methods and planners. Initial results

Title of thesis : Sequence Modelling to Detect Netwok Intrusions
Thesis abstract : Intrusion detection systems(IDSs) play a key role in detecting malicious activities and enable
administratorsin securing network systems. Anomaly based IDS profiles normal traffic behaviour and flags any
deviation from the model as anomalous. We propose anomaly based IDS for TCP based traffic. The work done is
in three parts - simple sequence modelling classfier, hybrid approach combining two IDS and a layered sequence
learner to explain the nature of TCP traffic. First, we propose a Hidden Markov Model (HMM) based IDS to
model TCP traffi c. The inherent sequential nature of TCP tra ffic is captured effectively using HMM. TCP packet
features are used to learn the parameters of the model. Various design choices and performance improvement
measures were included to make the model e ffective. The model gave high detection accuracy with very low
false positive rate on various data sets. Second, we propose a hybrid model combining the proposed HMM
classifier with a Na ve Bayes (NB) based classifier. This merging of classifiers is to address a few
shortcomings which prevented HMM model from being a stand-alone classifier. The NB model acts as an online
classifier with the HMM as its o ffline counterpart. The combined model was tested with various real-time data
sets and found to perform well. Third, we propose a layered model, containing an ensemble of basic HMMs, to
model TCP connections. Contrary to the usual notion of classifying connections, this model tries to explain how a
TCP connection evolves over time. Diff erent configurations of the model have been built and tested with very
long TCP connections.

Title of thesis : Universal Syllable models for language identification
Thesis abstract : Automatic Spoken Language Recognition makes extensive use of phonotactics for identifying a
language. The accuracy of phonotactic information depends upon the amount of data available for training. The
state of the art approaches capture the phonotactics in terms of phonemes. But building a phoneme tokeniser
needs labelled speech corpora which is expensive. In my work, I have suggested an alternative to phoneme
tokens, namely, syllable based tokens. Syllables implicitly capture the phonotactics. Modelling sequence
information requires modelling of syllable tokens by Hidden Markov Models (HMMs). Although, unsupervised
HMM clustering successfully determines syllable inventory in every language, it nevertheless, requires significant
tuning of parameters. It is suggested the use of a universal syllable models initially. These syllable models are
then adapted for every language. Experimental results on benchmark dataset show that the proposed approach is
very promising and performs quite well as that of a manually trained system.

Title of thesis : Traffic Verification - A frame work for port-based anomaly detection
Thesis abstract : An anomaly is an activity that deviates from the wellknown behaviour of the system. Anomaly
detection in networks is of interest from two perspectives: an organization’s perspective and an Internet Service
Provider’s (ISP) perspective. Protection of its computer network infrastructure is an important task for all
organizations. Organizations desire that their networks are robust and resilient to any kind of attack. Anomaly
detection forms an important part of this network resiliency. Also the ISPs want to maximize the utilization of their
resources. Hence an ISP would be interested to know any resource failure immediately so as to correct the
problem. ISPs would also be interested in safeguarding their network from malicious activities. We describe here
a Gaussian Mixture Model (GMM)-based traffic verification system as a paradigm for network anomaly detection.
The traffic characteristics aggregated over a period of time is given to the model to verify the validity of the traffic.
If the traffic does not obey the model then we raise an alarm flagging it as an anomaly.

Title of thesis : Matching of freeform shapes in 2D
Thesis abstract : Matching and retrieval of shapes, both in two and three dimensions, have been a topic of
interest to researchers in the field of computer graphics, vision and geometric modeling for more than a decade. A
shape is defied as a set of freeform curves/surfaces forming a closed loop. A freeform curve/surface is typically
represented in Bezier or B-spline form. A prominent approach to matching curved outline is the graph-based
approach, where a skeleton such as medial-axis or Voronoi-diagram is used for obtaining the graph. In general,
graph matching is a hard problem and the comparison costs increase proportionally with graph size and hence
slows down the process. Moreover, the computation of skeletons for freeform shapes is an intricate problem. The
main aim of this research is to use shape functions like the shortest path and medial axis for matching and
retrieval, because they are more robust, easy to compute/represent, and compact in terms of computer memory.
To aid in matching and retrieval, shape signatures are then obtained from shape functions.

Title of thesis : Closed Loop Control of Blood Glucose Levels in Diabetic Patients
Thesis abstract : Control of blood glucose levels in glucose-insulin regulatory system is necessary in the diabetic
patients. BGL is measured using a glucose sensor. To maintain constant BGL, a control strategy is implemented
in the computer using Matlab and the amount of insulin to be injected is estimated. A novel mathematical model of
delay differential equations for glucose-insulin interactions in diabetic patients is proposed. An observer is
designed to measure the state estimates of the model. These state estimates can then be used in the control
algorithm. A few parameters in the mathematical model are patient specific and these must be estimated for
accurate modeling. The control algorithm calculates the amount of insulin to be injected to the patient to maintain
the BGL in the normal range. This value is then fed to the infusion pump hardware and the drug is delivered
accordingly.

Title of thesis : Design and development of Wireless ECG device and implementation of heart rate detection
algorithm
Thesis abstract : A novel design of a portable low cost wireless wearable ECG device is presented. This device
acquires the raw ECG signal using electrodes placed on the chest of the subject. An analog circuit board
conditions this raw signal which is then sent to the microcontroller for further filtration of artifacts. A novel method
is used for phase compensation. Bluetooth module receives the filtered data from the microcontroller and
transmits it to the user’s phone where the ECG is displayed and simultaneously stored in text and JPEG format.
The recorded JPEG image can be transmitted to the doctor’s mobile phone via MMS and the latter can give an
instant feedback. The analog front-end (AFE) module is designed using low cost reliable components. TI’s
MSP430F47186 microcontroller runs the digital filters written in C language. The Bluetooth module ”WT12” is
from Bluegiga and the system requires 3 volts for operation. The Android application was written in Java for
acquiring, plotting and storing the data in the phone’s SD card, in text and JPEG formats. Samsung Galaxy Fit
android phone was used for the prototype design. All through the system design, cost incurred was kept to a
minimum.

Title of thesis : Formation Control of Multiple Autonomous Underwater Vehicles
Thesis abstract : Multi robot coordination and control for underwater robots is an area of significant importance in
many underwater missions. A new approach for leader follower formation control of multi AUV systems is
formulated. Termed state estimation based controller, this estimates the next desired position of the follower robot
from the past and current positions of the leader and follower robots. The control signals are then issued to the
follower robot to align it to the estimated trajectory. This control scheme has the capability to compensate for initial
errors and follow the leader under various operational scenarios. The system was simulated in Matlab/ Simulink
and is found to be efficient. A fleet of surface vessels were constructed which was used to test the real world
implementation of the system.

Title of thesis : New Capacitive Sensors for Safety Application
Thesis abstract : Determining human presence is a critical parameter attached to safety. Capacitive sensors
proves to be very low power consuming and efficient in this regard unlike IR , thermal or weight based sensors.
One such scenario is of babies being left behind in parked cars which seems to be unalarming yet has proved to
be fatal in many cases reported in different countries. Parents or guardians forgets their child inside car
(intentionally or un-intentionally) due to hectic urban lifestye. The temperature inside increases rapidly even on a
normal day. Since the thermoregulatory system in children are underdeveloped child often suffers from
hyperthermia. Sensors to detect the presence of a baby , like the ones used for adult seat occupancy have been
built to avoid such mishaps. The ones available are based mechanical switches, weight , thermal and optical
methods. Capacitive based sensors for such application are much more reliable.

Title of thesis : Outage and Goodput analysis in ARQ multiple access channels
Thesis abstract : Automatic repeat request (ARQ) protocol is used to combat packet losses in error prone
networks. It is a simple protocol which retransmits packet until it is received successfully at the receiver. ARQ
protocol is well understood in point to point communication and the optimal packet reliability for maximizing
goodput is known. In our work we consider ARQ in a fading multiple access channel (MAC) scenario where a
number of users transmits information packets to a single receiver. With ARQ, goodput (long term average of rate
at which packets are successfully received) is a function of transmission rate and packet error probability. Since
we consider a fading MAC, the packet error probability is given by the channel outage which is the probability that
a chosen rate cannot be sustained by the channel. In a MAC, there are two notions of outage probabilities:
Common and Individual outage probability. Under these two notions of outage probabilities, we analyse the
optimal packet error probability that will maximize goodput for different SNRs and number of users.

Title of thesis : Adaptive Training for Triphones with less amount of data
Thesis abstract : A large amount of data is needed to build a Speaker Independent (SI) model because of large
number of parameters. Building a SI model with less amount of data often causes a problem. Here, we develop a
new technique to speech recognition, where all the triphone states of Hidden Markov Model (HMM) are obtained
by linear combination of monophone Gaussian Mixture Models (GMM). Instead of directly finding the parameters
of triphone state, we just need to find the linear combination that gives GMM for triphone state. This allows
significant reduction in number of parameters, which enables us to build the model with less amount of data.

Title of thesis : Efficient Feature Extraction for Noise Robust Speech Recognition
Thesis abstract : The accuracy of Automatic Speech Recognition (ASR) systems degrades severely in noisy
environments. Many approaches have been developed in literature to address the problem of robust speech
recognition, which include feature-normalization algorithms, model based compensation and adaptation methods,
etc. While implementing these methods, there is always a trade-off between the improvement in recognition
accuracy and the computational cost introduced by them. Therefore, to approach this problem optimally, we focus
on feature space normalization, which basically tries to refine the feature space from noise as much as possible
using various techniques.

Title of thesis : ECONOMIC OPERATION OF SMART POWER SYSTEMS UNDER LOAD FREQUENCY
CONTROL
Thesis abstract : With the advent of Information Communication Technology, power systems have become
smarter. This facilitates a situation in which demand side management plays an important role in grid operation.
The first part of the thesis proposes a probability based model of the power gain achieved due to price based
demand response from thermostatically controlled loads. The advantage of this model is that an economic
operation from a consumer perspective is achieved. This model is then used to investigate the contribution of
demand response in Load Frequency Control. The results promise a positive potential for the participation of
demand response in Load Frequency Control. The second part of the thesis proposes an economic Load
Frequency Control scheme under a deregulated system in which competing generation companies are involved.
This scheme has been modeled as a stochastic game which is collaborative. The agents involved in the game
learn the optimal action, i.e. Nash Equilibrium of the game, with Reinforcement Learning based approach. The
advantage of the proposed scheme is that the generation companies produce optimal amount of power that is
required to minimize the cost of production of the system, preserving the concept of deregulation in the system
and competing among the companies. The simulation results show that the frequency deviation was also
minimized, which is the primary objective of Load Frequency Control.

Title of thesis : An active soft switching technique for phase shifted full bridge converters.
Thesis abstract : Full bridge converters are widely used for medium and high power applications. Phase shifted
full bridge converters are preferred because of their inherent zero voltage switching property for leading leg. ZVS
for lagging leg is load dependent. At light load conditions or for high input voltages, ZVS for lagging leg is not
possible. Many passive and active soft switching circuits are proposed in literature to address this issue. Passive
soft switching circuits are able to achieve ZVS for a wide range of load at the cost of reduced efficiency. The
novelty of proposed active soft switched circuit lies in achieving ZVS for active switches, ZCS during turn on and
turn off of auxiliary switches used. Since auxiliary switches are turned on for smaller durations, losses due to
additional circuit didn't have an impact on overall efficiency. A 350 W, 100 kHz and 200kHz prototypes are built to
validate the theory.

Title of thesis : Load optimized L2 mobility for LTE using OpenFlow switches
Thesis abstract : According to an estimate about mobile traffic forecasts, there will be an incredible growth in the
mobile data by the introduction of increased capacities of radio access technologies like LTE. The immediate
effect is the increase in signaling load pressure on the mobile backhaul. Hence, the present backhaul solutions
proposed for LTE, which are based on GTP cannot cope up with this increased signaling load on the core
network. This leads to the change in the direction of mobility implementation at layers other than network layer.
Mobility at Layer-2 is an attractive proposition since it hides mobility from network layer and consequently the IP
point of attachment remains static throughout the communication session. The basic issues of ethernet switch
based mobility schemes (such as poor scalability and flooding) make it complex to implement at Layer-2. But by
the advent of OpenFlow switches, the issues of typical ethernet switch are solved. We implemented a novel
mobility scheme using OpenFlow switches in the access and aggregation networks by making minimal changes to
the existing LTE mobility schemes. It is observed that handover latency and signaling load on the core network
are drastically reduced with a minimal increase in initial attach latency when compared with existing LTE mobility
schemes.

Title of thesis : Periodic Structures in Silicon Waveguides
Thesis abstract : Silicon photonics is an immerging and potential area of research which utilizes the conventional
CMOS and MEMS fabrication technology to realize various compact and high performance devices. In my
research, I have designed, fabricated and characterized Distributed Bragg Reflector (DBR) structures in silicon
waveguides. They have interesting device physics as well as a variety of uses in sensors and communication
devices. They can be used as optical equivalent for electronic filters which is an integral component of all-opticalsignal-processing. They are potential components in amplifieres and lasers. Also these structures can be used to
enhance, tailor or add some usefulness in the conventional optical devices like add-drop multiplexers,
interleavers, modulators, dispersion compensators, waveguide couplers, resonators etc. Though these structures
were well known and well implemented in many applications, their possibilities utilizing higher order diffraction
was not properly explored. As part of my research program, I have done the anlytical and numerical modelling of
these structures using coupled mode analysis and Fourier analysis. I have also demonstrated DBR in silicon
waveguides with eleventh order diffraction. The characterization results of the fabricated DBRs showed 85%
reflectivity and 2.5 nm full width at half maxima.

Title of thesis : Development of a LTE Channel Emulator
Thesis abstract : Modeling a channel is important wireless communication systems. A wideband wireless
channel exhibits behaviors like path loss, fading, multipath, shadowing, noise, ISI, propagation delay, Doppler
shift and is highly time varying. Any wireless system designed has to me made fairly robust against these channel
behaviors. To test such algorithms, it is practically impossible to use the actual physical channel. A channel
emulator is a device which can mimic the actual physical channel by taking certain control inputs from the user
and creating a link which behaves like a actual physical wireless channel. My work is on developing such a device
for LTE applications.

Partitioning Scheme
Thesis abstract : The excellent high-frequency performance of silicon germanium heterojunction bipolar
transistors (SiGe HBTs) makes them a suitable choice for radio frequency (RF) circuit applications. Efficient and
accurate non-quasi-static (NQS) models are required to predict the high-frequency behaviour of SiGe HBTs for
RF circuit design and simulation. The thesis presents the development of an accurate physics-based NQS model
using an improved charge partitioning scheme. The developed model is suitable for implementation in Verilog-A
and yields straightforward parameter extraction techniques. A more efficient NQS model is also developed that
offers similar accuracy and lesser simulation time. The bias dependence of the NQS model parameters is also
discussed.

Title of thesis : Geometric and Photometric Reconstruction of Large Missing Regions in 3D models
Thesis abstract : Generation of digital 3D models of real world structures is a popular theme in computer vision,
graphics and virtual reality. In general, post-processing of the acquired or generated point clouds is warranted to
generate ‘watertight’ 3D models. However, there may naturally exist structures that show large damaged or
broken regions (e.g.: archaeological structures) due to numerous enviromental and man-made forces of
degradation at work. Using traditional post processing methods, the ‘watertight’ 3D model generated will also
contain such a damaged region, which may result in visually unpleasant outputs for applications such as a
‘Virtual Tour’. In this work, filling-up of such naturally existing damaged regions (or, holes) in 3D models is
addressed. Once a salient geometric reconstruction of the holes in a broken 3D model has been achieved, an
intensity filling-in (or, inpainting) for the reconstructed surface points is the next objective. This part of the work
aims to perform inpainting of the per-colour channel brightness information over the 3D geometry itself for the
hole-filled region which helps in making the inpainting process view independant. As a direct result of this, even
the reconstructed surface points occluded in a given view can be intensity inpainted.

Title of thesis : Spectral Analysis of Non-Ideal Plasma in Waveguides and Designing such Waveguides
Thesis abstract : We generated plasma in a rectangular waveguide at different voltages and different flow rates
of gases. The motive was to test the characteristics and the line spectra of soil. The temperature of the plasma
was calculated using comparison with blackbody radiation and that was used to chracterise the nature of the
plasma. The conductivity profile of the plasma was then used for the 3D Modelling of our experiment. A relevant
circular waveguide was used for the same experiment as it is easier to design and it also reduces the cost of the
experiment . For the spectral analysis of the plasma, a UV-Visible spectrometer which gives a resolution of 1nm
to 3 nm lines is also designed.This is what is required for a soil analysis and that is also the reason why a low cost
design is even possible.

Title of thesis : Design and Development of a Novel Inductive Loop Sensor System
Thesis abstract : This project presents a novel inductive loop sensor which can detect vehicles under a
heterogeneous and less-lane disciplined traffic and thus can be used to support a traffic control management
system in optimizing the best use of existing roads. The loop sensor proposed in this report detects large (e.g.,
bus) as well as small (e.g., bicycle) vehicles occupying any available space in the roadway, which is the main
requirement for sensing heterogeneous and lane-less traffic. To accomplish the sensing of large as well as small
vehicles, a multiple loop system with a new inductive loop sensor structure is proposed. The proposed sensor
structure not only senses and segregates the vehicle type as bicycle, motor cycle, scooter, car and bus but also
enables accurate counting of the number of vehicles even in a mixed traffic flow condition. A prototype of the
multiple loop sensing system has been developed and tested. Field tests indicate that the prototype successfully
detected all types of vehicles and counted, correctly, the number of each type of vehicles. Thus the suitability of
the proposed sensor system for any type of traffic has been established. This project also presents a new pattern
of multiple loops that improves reliability. Output data from this system has been processed using a machine
learning algorithm to automate the classification process.

Title of thesis : Stability Analysis of Switched Systems with "mixed" small gain and passivity property
Thesis abstract : This paper deals with the stability of switched systems and their feedback interconnections.
Each of the subsystems of the total switched system possesses "mixed" small gain and passivity property, i.e, the
system has small gain as well as passivity property. A linear feedback system is said to possess “mixed” property
if its loop gain is less than unity in certain frequency intervals while being passive in the rest. An equivalent
definition of this property in time domain is given for both linear and nonlinear systems. It has been proved that a
system with the mixed property is dissipative and there exists a storage function such that the dissipativity
inequality is satisfied. A definition of dissipativity for switched systems is described, where each subsystem is
assumed to have independent storage function. Using this definition, it is shown that a switched system with the
mixed property is stable under certain conditions. Also, the negative feedback interconnection of two switched
systems is dissipative and hence stable.

Title of thesis : Effects of RF Wave Induced Electric Field On Blood Proteins
Thesis abstract : The goal of my MS is to investigate the formation of the screening potential around charged
molecules in biological tissue. Of interest is the time scale on which this potential is formed, and the nature of this
potential when RF at higher frequency that the inverse time of formation is applied to such molecules. The
motivation for this study is to understand mechanisms by which Electromagnetic Waves from a mobile handset
could affect biological tissue. Biological cell membranes are selectively permeable which means that they allow
only certain molecules to pass through them. One observation in these studies has been that in the presence of
RF, the selective permeability of cell membranes does not function correctly. Specifically some studies have seen
traces of albumin in the brain, which could only be due to the malfunctioning of the blood brain barrier. Before
going to the level of analyzing the movement of proteins through such membranes it becomes necessary to know
their behavior in the main solvent of the human body i.e. blood. Under normal circumstances RF fields should not
have any physiological effect.However, albumin(main blood protein) has a charged sheath around it to shield this
charge. Should it change in size, for example, the diffusive rates could change. This can be a potential cause of
leakage of albumin across blood-brain-barrier.Thus it becomes necessary to understand the behavior of this
Debye shield in presence of RF signal. In my project it will be demonstrated how an RF signal affects the sheath.

Title of thesis : State observer design for battery management system of Lithium ion cells for hybrid electric
vehicle applications
Thesis abstract : To develop algorithm for a battery management system (BMS) which can 1. Accurately
estimating capacity and health of Lithium ion battery 2. Control Charging / discharging more efficiently and safely.
The internal dynamics of lithium ion battery is characterised by a set of Partial and ordinary differential
equations.These equations forms an electrochemical model of the battery. These equations can be numerically
solved for estimating centain internal state variables of the cell. A state observer has to be developed for this
purpose. By knowing these states, the battery can be charged more safely and efficiently than the conventional
voltage based charge/discharge control method. Accurate value of State of charge and state of health of the
battery can also be calculated from the state measurements.
The challenge is to find out an alogorithm which
can perform in real time without compromising on accuracy of state estimations.Such high performance algorithm
can be useful for BMS used in hybrid electric vehicles.

About me :
A person with interests ranging from evoltionary biology to game theory to cosmology to quantum physics. I
like to cook, I like to swim, I like to draw and paint and I wish to lay my hands on many more things I havent tried
yet. Being a scientist was always my dream, no matter in which field. Now it stands as a partly fulfilled one. After
coming into engineering, Control system became dearest of all subjects as I was fascinated to see a feedback
mechanism playing at every corner along all the known areas of science - from economics to biology. For me it is
like a portal to travel everywhere and taste everything in science. Hence I decided to wander around in control
engineering.
My goal is to work in any area in control system where I can do extensive research. I always like to extend
my boundaries while doing any kind of job. As Maria Sharapova once said: " I hit a ball for a living, but I have
that passion to keep learning ".

Title of thesis : Discrete Control of Excitation System for Transient Stability Improvement
Thesis abstract : Transient stability is the ability of a system to maintain synchronism when subjected to a large
disturbance. Maintaining transient stability is important because any incidence of a fault may lead to generator
tripping due to loss of synchronism. Since cascaded tripping of generators leads to black out, there is a need to
improve the transient stability of the system. This can be achieved by proper system design and use of control
action. I was involved in developing a control algorithm based on the concept of equal area criteria and
implemented the same on the multimachine system with braking resistor in which generator is modelled in detail. I
have used the concept of wide area measurement in designing the algorithm and have taken communication
delay into consideration. I have been trying to decide the rating of braking resistor based on the energy function
and sensitivity. Also, I have been trying to implement the same control algorithm on excitation systems.

Title of thesis : Restoration of foggy motion blurred images
Thesis abstract : Bad weather like fog or mist leads to a contrast-loss in the captured image. This degradation is
a function of the scene depth. Simple histogram based equalization methods will not handle such space-variant
degradations. Hand-held cameras are prone to shake and hence the final image is also motion blurred. We have
studied the restoration of such foggy motion blurred images.

Title of thesis : Sensor Networks
Thesis abstract : Wireless Sensor Networks- Increasing CO2 concentration in atmosphere is one of the major
cause of global warming. increased soil respiration in recent years is considered a major source. Suggested
sources for increase in soil respiration are microbes (due to increase in temperature) and plant roots. The need is
to come up with a hardware which can do soil and atmospheric CO2 measurement with low power consumption
and transmit the data over wireless to a personal computer (PC). We are in the process of designing such a
system. Optical Sensor Networks- India Based Neutrino Observatory (INO) has about 30,000 neutrino detector
each generating data at about 500 kbps. A robust network is required to collect data from all the nodes accurately.
Keeping in mind the EMI due to high voltage surroundings, optical fiber network looks a suitable option. We are in
process of designing a passive optical network according to the need at INO.

Title of thesis : Risk Management in Private Equity Investments: Evidence from the Infrastructure sector
Thesis abstract : Key Words - Private Equity, Infrastructure Deals, Syndication, Staging, Strategy, Investments,
Risk and Uncertainty, Information Asymmetry, PE firm characteristics, Infrastructure company characteristics,
Deal characteristics, Country risk characteristics Purpose - This dissertation presents an analysis of the choice
for, drivers of and exent of syndication and staging when Private Equity (PE) invest in infrastructure projects. Both
syndication and staging of investments have been recognised as non-monetary tools used by PE investors to
mitigate uncertainty and information asymmetry in difficult enviroments. Previous studies with respect to
syndication or staging have been limited to developed countries; with few studies synthesizing the overall findings
of research to support investment decisions at a sector level. Infrastructure projects have long maturities (5-40
yrs) and resource flows into the project only after they become operational, risk characteristics which are different
from manufacturing / corporate finance projects. With PEs increasing their scale of investing in infrastructure, an
examination of syndication / staging would shed insights into strategies used by PE firms when investing in such
non conventional projects. Objective / Design / Methodology / Approach - The main objective of this dissertation is
to examine syndication and staging strategies of PE firms and the relationship between these two strategies when
PEs invest in infrastructure. This is achieved by three sets of studies - one, that analyses syndication of PE
investments, two, that examines the staging of PE investments and three, that explores the relationship between
syndication and staging of PE investments. This thesis uses secondary data analysis; and the empirical analysis
uses a multi methodology approach to test the various objectives at hand. Scope of infrastructure projects
includes global industrial / energy deals, transport deals and water and utilities deals from 1990 - 2009.

Title of thesis : Intra-Individual and Inter-Individual factors affecting expatriate intercultural development and
engagement
Thesis abstract : Organizations actively focus to prepare their managers to function effectively in a
global workplace; they are constantly seeking better direction for effectively building skills. Off- the-shelf programs
and learning about national culture, though important, are insufficient in equipping the managers in the much
needed aspect of building intercultural competencies. This study investigates intra-individual and inter-individual
factors that have an influence on the intercultural development and engagement of international workers. The
evidence for the specific factors such as emotional intelligence, openness to experience, cosmopolitanism, trust
as well as ratings of social support, perception or out-group and frequency of interaction were gathered from 461
international employees using a survey. Results obtained using SEM model, throws new light on some aspects of
intercultural development. Cosmopolitanism, a previously unexplored concept in this area, emerges to the
forefront. Hypothesized relationship of intercultural development with emotional intelligence, social support and
frequency of interaction show contrasting results. A comparative analysis of Indian and non-Indian respondents
highlight a need for tailor-made programs to prepare managers for working in a global context. This study has
implications for selection, training and development, career management and diversity management.

Title of thesis : Split ordering decisions in single period supply chain with contracts and information updating
Thesis abstract : The lifecycle of a product has become short due to the innovation in technology, and these
products have the attributes of seasonality and perishability. The challenges in integrating the supply chain pose
issues like managing complex structure of supply chain, demand uncertainty and leftover units after the selling
season. Due to these reasons, the supply chain members of such products are facing difficulties in selling their
products and making decisions in order quantities. These issues can be resolved by using variants of the classical
newsboy (single period) model which helps in determining optimal order quantity by managing the trade-off
between the risk of over-stocking and under-stocking. We have introduced the concept of “split-ordering” to
absorb the variability in demand, thereby reducing the expected over-stocking and under-stocking costs.
Coordination mechanisms (supply chain contracts) have been introduced for sharing the risks and rewards among
the supply chain members. Mathematical models have been developed for various scenarios and stochastic
dynamic programming technique is used to solve the models.

Title of thesis : *Understanding Exchange Offers and Enhancing its Efficacy
Thesis abstract : * An ‘Exchange offer’, is a sales promotion offer (in durables) that takes back a used product
as part payment, in exchange for a new one. The Indian consumer’s reluctance to retire a product that is still
functional, space constraints to store it while purchasing an upgraded product and a need to gain maximum value,
make exchange offers a popular sales promotion tool. Further, the practice of recovering used products lends it to
be refurbished, remanufactured or recycled in an environmental friendly manner. This research seeks an
explanation for the rise of this phenomenon in various theories like the Prospect theory and the Subjective Theory
of Value. Further, my study traces the relevance of an exchange offer to its stakeholders viz. the firm, the retailer
and the customer. It also reveals the current trends that make up an exchange offer advertisement. This study will
then, demonstrate ways of making the exchange offer advertisement more effective. This research contributes to
academic literature by providing a better understanding of exchange offers. Marketing practitioners stand to
benefit from the demonstration of new applications in message framing that improve the efficacy of exchange
offers.

Title of thesis : A Study of Business Model Innovation in the India- A case of the Pharmaceutical Industry
Thesis abstract : An industry that is considered most innovative by the Indian government has been unable to
cope with the onslaught of foreign arrivals in its own native ground. This is chiefly because Indian
Pharmaceutical Industry is unable to produce original compositions and add to their patent corpus. Post 2005,
with changing regulations and legislations, Indian firms have been mandated to introduce original formulations
and pharmaceutical ingredients into the market. The inability to file patents except a few deserving firms, Indian
firms have adopted alternative strategies to combat competiton for survival. The end of process patent regime is
a bad news for the Indian firms. While exporting, alliances and off patented drugs are alternative strategies for
growth they would not be able to confer sustainance and longer lifelines to these firms. Long term survival
strategies may involve looking at the industry challenges through a different lens and suggesting models that
sideline the conventional innovation management adoption and assimilation techniques,. The determinants,
antecedants and types of Innonvation need to viewed differently. The capabilities and competencies of the
industry is examined from the physical, finacial and human side. The systems processes and resources have
been studied. Is Buiness Model Innovation an answer to their long term survival and growth of Indian
Pharmaceuticla Industry? Can business model Innovation give a turn around to the way Indian Pharma firms are
operating? Can Business Model Innovation boost competiton in the Indian market among the domestic firms and
also challenge the profits of MNCs in india? An attempt is made to develop a partial working model for the
industry.

Title of thesis : Influence of industry and academic collaborations on innovation capabilities of industry in context
of software and IT companies. A comparative study of the German and Indian Research Eco-systems.
This study aims at understanding how industry and academic collaborations influence
Thesis abstract :
innovative competitiveness of software and IT sector industries. A tech-innovation embodies information and thus
reduces uncertainty about cause-effect relationships in problem solving. While innovation is indicated by patent
counts, new product announcement and other factors, the said innovation is communicated through certain
channels over time among the members of a social system. This is called the diffusion of an innovation.
Universities not only play a vital role in this information generation but also act as a channel through which the
information could be communicated. This study aims to establish how industry and academic collaborations
provide various avenues of improvement with regards to the innovative competitiveness of a company actively
involving itself in the collaboration. For the purpose of this study, a comparative analysis of the research ecosystems which influence innovation in Germany and India, has been conducted with the help of empirical
evidence collected through questionnaire and personal interviews. The variables indicate channels of knowledge
transfer and their significance, barriers to these collaborations and cultural aspects. Though this cannot give an indepth idea on the differences between the two eco-systems, it throws light on the basic differences. Based on the
responses, the common opinion was that, academia can contribute to innovation in terms of knowledge transfer
which can take place through the channels of: human, intellectual and structural capital exchange. The study is
however not devoid of pro-innovation bias and we aim to explore this area in the future.

About me :
I did my schooling and Under-graduate studies from Hyderabad. My under-grad was in Textile Engineering. After I
finished my Under-grad, I worked in the Department of Textile Engineering on a Polymer science related Project
for a twelve months. While in college,I and a few other friends felt the need to improve the facilities in our college
by several folds and worked accordingly. During my stay at IIT Delhi, I worked as a part-time Associate HR for a
student start-up called "thewittyshit.com". I observed that working with people was one thing that constantly
excited me. I realized my strength in management and started my Masters in Human Resource and
Organizational Behavior specilization. I performed well and got selected for an Exchange program in "Technical
University of Munich" for the Summer semester from April 2012 to September 2012. As a part of my course work,
I studied Technology and Innovation Management and realized the potential implications of this field in India. I did
a case study as a part of my Master's thesis which aims at understanding how industry and academia
collaborations influence innovation capabilites of an Industry.
I am interested in Reading and Writing.

Title of thesis : Understanding the generational differences and diversity climate of the organization in state of
psychological contract fulfillment, and its impact on employee’s cognitive responses: A conceptual analysis
Thesis abstract : The study of psychological contract is of increasing interest to organizations, practitioners, and
researchers alike and is an important area of inquiry for management research. It is necessary to study the
perceived psychological contract fulfillment, in order to better understand the employer- employee relationship.
Organizations must also recognize the influence of the values and work preferences of employees belonging to
different generations, impact of diversity climate of the organization and its effects on employee’s cognitive
responses, in order both to retain staff and to groom future leaders. This paper examines the employeeemployer exchange in terms of perceived psychological contract fulfillment and its effect on employee’s
behaviors and attitudes. This paper also aims at studying how employees belonging to different generational
cohorts employed in diverse climate perceive their state of psychological contract and its resulting effect on their
attitudes and behaviors. Based on literature, a conceptual framework is developed to link all the variables which
will be tested in a follow up empirical study. It is proposed that employees belonging to different generations
working in a positive diversity climate will report psychological contract fulfillment which in turn will have significant
impact on work related attitudes and behaviors.
If organizations are able to modify their cultures and work
environments to adequately balance the employer employee relationship, then there is a possibility of
improvement in attitudes and behavior of employees and this in turn lead to better organizational performance.
The findings from the present research would add considerably to the literature and practice on generational
differences, diversity climate and state of psychological contract fulfillment. This research would also contribute to
academic literature given the limited amount of studies in this area in the Indian context.

Title of thesis : Topics in the Competitive Newsboy Model
Thesis abstract : In the modern world, a product life cycle is very short because of the innovations in
technology.Supply chain management is about matching supply with the demand, especially with the inventory
management.Too much of supply leads to inventory risk(cost of unsold inventory) whereas too much of demand
leads to supply risk(cost of insufficient supply).A supply chain with a manufacturer selling seasonal products to
two retailers(buyers) working in a common market is considered.The products are substitutable so that, if there is
any unsatisfied demand in one retailer, it will go to the other .The retailers(acting as a newsvendor) need to
determine the optimal order quantity so that they could capture the maximum market.Both the retailers make
demand forecasts independent of each other, and is a private information.Also, they make an assessment about
the forecast of the other retailer knowing his own forecast.The equilibrium of the competition game is to be
determined which will indicate the optimal order quantity of each buyer.Game theoretic concepts are used for
modelling the problem.

Title of thesis : The Effect of Firm Structure on Cash Holdings of Indian Firms
Thesis abstract : For companies to survive in the increasingly competitive scenario with high capital market
imperfections, liquidity management has become a major concern especially during the crisis period and at times
of macroeconomic uncertainty. Companies with sufficient cash on hand may escape the need to rely extensively
on credit provided by banks as well as increasingly costly credit markets. The effect of firms’ organizational
structure (i.e., whether a firm is diversified or focused) on cash holdings is examined from an Indian perspective.
The study attempts to investigate and explain the difference in cash holdings level between diversified and
focused firms and also how cash holdings affect firm valuation.

Title of thesis : Sector Index : Do they tell the right story?
Thesis abstract : Index in emerging economies are constructed similar to developed markets, although there
exist significant differences in the characteristics of the markets. Indian capital markets having been proved to be
inefficient, index construction by free float market capitalization method systematically under weights or over
weights the constituent stocks, thereby biasing the index. The effectiveness of a uniform method of index
construction in the context of the distinctive characteristics of the sectors and the need, if any, for dissimilar
method of index construction forms the core of this study. The relationship between the sector index and the nonindex stocks in a representative set of sectors is studied. Alternative methods of index construction and their
effectiveness are then compared. Daily closing price data of stocks listed in one of India’s largest exchange,
National Stock Exchange, is analyzed. By testing for cointegration between the sector index and its stocks,
evidence has been found that a majority of stocks in specific sectors are cointegrated with a subset of the
constituent stocks rather than the index itself. It is concluded that market cap based index construction might not
accurately represent the sector and a uniform method of construction for all sectors might not be appropriate.

Title of thesis : Power generation using Mechanical Wave Energy Converter
Wave energy, Power take-off mechanism, Risk analysis,
Thesis abstract : ABSTRACT KEY WORDS:
Mechanical wave energy converter, Point absorber, Model tests
Oil crisis in recent years has compelled
exploration of alternate resources of renewable energy; focus is set on large-scale power generation from ocean
waves. Potential for improvement of technologies on wave energy is high while survivability and reliability of many
devices are still to be demonstrated for offshore operations in particular. Salient advantages of wave energy are
namely: i) time required for research and development is shortened by the proven re-engineering technologies of
offshore oil and gas, wind power and shipbuilding industries; ii) wave power is predictable and dependable with
the ability to forecast wave power spectrum, days in advance; iii) environmentally benign and non-polluting; and
iv) energy density being the highest among renewable energy sources. Power available from wave energy is
considerably high in the heave degree-of-freedom. Recent research activities on wave energy converters deploy
hydraulic and pneumatic devices as power take-off mechanisms (PTO); complexities in the conversion
mechanisms result in expensive and high precision machining. Although shore line devices like oscillating water
columns do not require deep-water moorings or long lengths of underwater electrical cable, wave power exposed
is relatively lesser despite being an economical alternative. Recent studies show that use of hydraulic and
pneumatic devices as power take-off mechanisms result in complexities in the conversion mechanisms due to the
requirement of expensive and high precision machining. Experimental studies carried out by various researchers
on scaled model of wave energy devices show unique set of challenges in the integration of prime movers and
generators. Average wave energy potential along Indian coast is around 5 to10 kW per meter length of wave crest
which shall yield to a maximum of 20 kW/m during monsoon period. The present study describes feasible design
of a new mechanical wave energy converter along with the detailed design of its components that employs point
absorber as wave energy capturing device; proposed device is simple and easy to fabricate and maintain. The
scope of present work is limited to harness wave energy using point absorber in heave mode using a mechanical
power take-off mechanism. For harnessing wave energy, linear heave oscillation of the buoy is converted into
rotary motion through the design. Risk analyses are carried out on the proposed device using failure mode and
effects analysis that estimates risk and failure rate of different components; design modifications are made to
improve the proposed design of the device. Failure modes are highly detectable in the improved design, which is
one of the major advantages. Detailed experimental studies are also carried out on the scaled models of the
proposed devices to verify their functionality and suitability for operational sea states of Indian coast. Desired trials
in design and experimental studies are carried out to improve mechanical advantages of the wave energy
converter. Preliminary analyses are carried out to arrive at the design configurations of the newly proposed
mechanical wave energy converter. Various components are critically examined for their performance vulnerability
as a part of the preliminary analyses. Experimental investigations are carried out on the scaled model (1:5.5) of
the device to estimate its efficiency. Two floating buoys namely: i) 620 mm diameter and 500 mm height; and ii)
800 mm diameter and 700 mm height are deployed to draw power from the encountering waves. Overall
efficiency of the device is computed on the basis of average power measured at the output shaft. Based on the
experimental studies carried out on the device, it is seen that fluctuations in electric power generated from the
output shaft are reduced significantly by installing the flywheel. Design modifications made in the device
enhanced the mechanical efficiency from 13 to 19%. It is also seen that electric power output of the device
increases with the increase in wave height. Maximum electric power available at the output shaft of the device is
for 30 cm wave height and 2.8 s wave period, which is a near-resonance period of the float. Power available at
the shaft of the prototype device is significant for the developed mechanical system and is comparable with other
commercial alternatives available at present; compact design, cost effectiveness, ease of fabrication and cheap
maintenance make the proposed device more attractive. Operational wave period for the proposed device is in
the range of 5-8.2 s.

Title of thesis : Modeling and Simulation of Minimum Quantity Grinding (MQL) of Nickel Based Super Alloys
Thesis abstract : For decreasing environmental and health hazards, change from wet cutting to dry/near-dry
cutting is highly recommended. In recent years, Minimum Quantity Lubrication (MQL) machining is regarded as a
promising method for reducing machining cost and cutting oil, while improving cutting performance; thus, it has
been investigated vigorously. Minimum Quantity Lubrication (MQL) has a good advantage of green, lubricating
and cooling effect. Very few investigations have been carried out on the influence of MQL parameters, such as oil
flow rate and air pressure on droplet size. The work aims to develop a simulation model to replicate the mist
formation in MQL grinding using Fluent based Computational Fluid Dynamics (CFD) flow solver. The MQL
parameters considered are air pressure and the mass flow rate. Simulation of the atomization under turbulent
conditions was done in discrete phase model (DPM) owing to the fact that oil mass flow rates are very low and oil
acts as a discrete medium in air. Jet velocity and droplet diameters were obtained under different inputs to find the
optimum value of air pressure and mass flow rate of oil to achieve the better results in MQL grinding of superalloy
(Inconel 751).

Title of thesis : Studies on the propagation of feature-guided ultrasonic waves in plates with small radius
transverse bends
Thesis abstract : Investigated the influence of bends constituting the profile of annular polygonal structures on
ultrasonic guided waves propagating along their axis. Considering a single bend as a bent plate connects this
problem to the better-understood physics of guided waves in straight plates. Using 3D finite element (FE)
simulation validated with experiments showed that bends in plates act as features that can concentrate and
guide ultrasonic energy along their length. Two interesting feature-guided modes are idiscoveredwhen the bent
plate is subjected to ‘in-plane’ or axial excitation applied uniformly along a through-thickness line bisecting the
bent edge. This mode is shown to be more strongly generated in smaller angle bends where it has a low
attenuation. The results are discussed in light of simple modal studies performed using the Semi Analytical Finite
Element (SAFE) method.

Title of thesis : Micro-grooving studies on different ceramic materials
In general there are two strategies adopted in machining of ceramic materials. They are
Thesis abstract :
removing the material at lower depth of cut and machining the material at higher temperature. While removing the
material at lower depth of cut, material behaves in a ductile manner, whereas at higher temperature above glass
transition temperature, the material softens and behaves as a ductile material. It is essential to understand the
mechanism of material removal that helps to identify the desirable conditions of the machining process. The
mechanism of material removal changes during ductile to brittle transition of work piece material. So for
enhancing the ceramic machinability. The objective of the present work is to study the material removal
mechanisms in a scratch test with effective strategy in condition monitoring to identify the conditions of ductile to
brittle transitions in the different ceramic materials using Acoustic Emission sensor.

Title of thesis : Rolling Contact Fatigue behavior of polymer nanocomposite.
Thesis abstract : Polymeric viscoelastic materials are replacing metallic components in many engineering
applications because of their superior tribological and self-lubrication properties over metals in light load
applications. Polymers are reinforced with micro and nano particles in order to widen the application of polymeric
materials for engineering components like gears, bearings, cams, wheel and rail and more. One can find a large
number of research studies of composites filled with micro and nano particles primarily in sliding conformal
contact conditions. However, the rolling contact fatigue behavior is different from the pure sliding contact behavior.
Research on rolling contact fatigue of polymer materials is scarcely available and there is a tremendous lack of
knowledge in this area with respect to the polymer nanocomposites. Current study involves the investigation of
rolling and rolling- to-sliding contact mechanisms and mode of failures in rolling contact mechanism. The research
also involves finite element study of viscoelastic polymer material under rolling contact fatigue conditions using
ABAQUS.

Title of thesis : Modeling and Analyses of Forces and Hole Quality in Micro-drilling of Glass/Carbon Fabric
Laminated Composites
Thesis abstract : Aerospace and automobile industries use components made of composites which require
micromachining operations to be carried out. Excessive thrust and torque are detrimental to the life of the microdrills, and the quality of holes produced. This work investigates the cutting forces and quality of the holes
produced during micro-drilling of plain sheet (matrix material), glass fibre and carbon fabric laminated plastics.
Prediction models for thrust force and torque are developed based on drill geometry and minimum uncut chip
thickness and validated with experimental data. The results show good agreement between the measured and
predicted values. Delamination damage, roundness error and diameter of these drilled holes are measured and
analyzed with variation of the process parameters. The results indicate that the good quality, high aspect ratio
micro-holes can be produced by selecting proper process parameters and strategy.

Title of thesis : Finite Element Analysis of Magneto-Electro-Elastic structures under Thermal environment
Thesis abstract : Magneto-electro-elastic (MEE) composite materials have the ability to generate magnetic,
electric and mechanical responses when they experience a thermal stimulus due to its significant coupling
between mechanical, electric, magnetic and thermal fields, which are potentially useful in smart or intelligent
structure applications.These composites provide the product properties (pyroelectric and pyromagnetic ) strong
enough to be useful for many practical applications. For example, enhancing the performance of more traditional
sensors. Response studies are carried out for the application of two phase MEE materials as sensor bonded to
mild steel beam, plate and shell under thermal environment. The aim of the study is to to examine the pyroelectric
and pyromagnetic effects on MEE sensors. These studies will be useful for enhancing the performance of
magneto-electro-elastic sensors under thermal environment.

Title of thesis : Parametric identification and damage detection of structures using transfer matrix and state
vector in the time domain.
Thesis abstract : Parametric identification of a structures is posed an inverse problem in which the parameters
of the structure are identified from input and output responses of the structure. A new structural identification (SI)
method based on Transfer Matrix (TM) concept is proposed here to identify structural parameters. Transfer
matrices based on lumped mass and the more accurate consistent mass models are used here, based on
displacement measurements in the time domain. The consistent mass based TM is derived from the dynamic sti
ness matrix of a beam element with and without damping. The state vector at a location is the sum of the internal
and external contributions of displacements, forces and moments at that point - when multiplied with the TM, we
obtain the adjacent state vectors. The method of identification proposed here involves predicting the
displacements at certain locations using the TM, and comparing them with the measured displacements at those
locations. The mean square deviations between the measured and predicted responses at all locations are
minimized using an optimization algorithm, and the optimization variables are the unknown sti ness and damping
parameters in the TM. A non-classical heuristic Particle Swarm Optimization algorithm (PSO) is used, since it is
especially suited for global search. Di erent strategies for calculating the initial state vector, as well as two
identification processes such as simultaneous and successive methods are discussed. Numerical simulations are
carried out on four examples ranging from a simple spring mass system to a nine member framed structure. The
method is also experimentally validated on a cantilever and a substructure of a fixed beam.
A new transfer
matrix has been developed for cracked beam elements. Using the TM for cracked beam element the seviority of
damage and its location also detected. The speed and accuracy of identification using this method are good. One
main advantage of this method is that it can be applied at any portion of the structure to identify the local
parameters in that zone without the need to model the entire global structure.

Title of thesis : Theoretical and experimental investigations on series hydraulic hybrid system for passenger
vehicles.
Thesis abstract : Today, non-availability of gasoline and its high price compel industries like automobile,
agricultural machinery and construction machinery find an alternative technology that could create fuel efficient
and energy saving systems. In this current scenario, Hydraulic hybrid systems are mitigation measure for the
current fuel crisis. It is a combination of two source of power, typically, one energy source is used for the
conversion of fuel to energy and the other source is used as storage unit. Series hydraulic hybrid system consists
of subsystems such as prime mover, hydraulic pump, hydro-pneumatic accumulator and hydraulic motor in series
configuration. In conventional systems, kinetic energy in wheels is lost as heat energy during mechanical friction
braking, but, series hydraulic hybrid system has the capability to regenerate the kinetic energy into useful
hydraulic energy and it's called hydraulic regenerative braking. Scope of work : Mathematical model of series
hydraulic hybrid system is developed and subsequent simulation of the system is carried out. To achieve
maximum transmission efficiency,a multi-objective parametric optimization is carried out on system mathematical
model to get optimal system parameters . To control the power from two sources efficiently,a power management
control strategy is developed . Experimental investigations on series hydraulic hybrid system are carried out to
validate the control strategy and simulation results.

Title of thesis : Structural Identification Using Improved Artificial Neural Networks
Thesis abstract : Purpose- The main purpose of the present investigation is to provide an effective and simple
technique to structural damage identification particularly to identify the crack in a structure. Artificial neural
networks approach is an alternative to identify the extent and location of the damage over the classical methods.
Radial basis function (RBF) networks are good at function mapping and generalization ability among the various
neural network approaches. RBF neural networks are chosen for the present study of crack identification.
Design/Methodology/Approach- Analyzing the vibration response of a structure is an effective way to monitor its
health and even to detect the damage. A novel two-stage improved radial basis function (IRBF) neural network
methodology with conventional RBF in the first stage and a reduced search space moving technique in the
second stage is proposed to identify the crack in a cantilever beam structure in the frequency domain. Latin
hypercube sampling (LHS) technique is used in both stages to sample the frequency modal patterns to train the
proposed network. Study i s also conducted with and without addition of 5% white noise to the input patterns to
simulate the experimental errors. Findings- The results show a very good significant improvement in identifying
the location and magnitude of a crack by the proposed IRBF method in comparison with conventional RBF
method and other classical methods. For a typical test case, the crack depth was identified with 0.80%
identification error by the proposed IRBF method in comparison with 6.59% by the other classical methods. It
takes very less computational effort to identify the crack as compared to other hybrid neural network approaches
and classical methods. Originality/value- The proposed novel IRBF crack identification technique is unique in
originality and can identify the crack location and crack depth with very good accuracy, less computational effort
and simple technique.

Title of thesis : Experimental studies on thermal performance of Phase Change Material (PCM) based heat sinks
Thesis abstract : Experimental investigations on finned heat sinks filled with phase change materials for thermal
management of portable electronic devices. The phase change material (PCM) used is n-eicosane and is placed
inside a heat sink made of aluminium. Aluminium acts as thermal conductivity enhancer (TCE), as the thermal
conductivity of the PCM is very low. The heat sink acts as an energy storage and a heat-spreading module.
Studies are conducted for heat sinks on which a uniform heat load is applied for the unfinned and finned cases.
The test section considered in all cases in the present work is a 80 x 62 mm2 base with TCE height of 25 mm. A
60 x 42 mm2 plate heater with 2 mm thickness is used to mimic the heat generation in electronic chips. Heat sinks
with pin fin and plate fin geometries having the same volume fraction of the TCE are used. The effect of different
types of fins for different power level (ranging from 2 to 7 W) in enhancing the operating time for different set point
temperatures and on the duration of latent heating phase were explored. The results indicate that the operational
performance of portable electronic device can be significantly improved by the use of fins in heat sinks filled with
PCM.

Title of thesis : CONJUGATE HEAT TRANSFER FROM A FLAT PLATE WITH COMBINED IMPINGEMENT
AND FILM COOLING
Thesis abstract : Several cooling schemes are used in gas turbine blades to ensure that the blade temperature
and thermal stresses are within safe limits. Among them, film (on external surface) and impingement (on internal
surface) cooling are frequently used. Previous researchers investigated either film cooling or impingement cooling
independently. However, investigation with the combined film and impingement schemes are sparsely reported. In
the present paper, such a study on a flat plate will be reported with experimental as well as computational
investigations. External side of the plate is exposed to hot mainstream as well as to the (film) coolant. The other
(internal) side experiences impinging air jets. A specific geometric configuration with multiple staggered rows of
cylindrical film holes and a matrix of impingement holes are considered. Each film hole has a stream-wise
injection angle of 35° with length to diameter ratio of four. Thermochromic liquid crystal (TLC) technique is used
to measure the surface effectiveness. The k-omega SST model is used in CFD simulation. The grid convergence
index (GCI) method is used for the grid refinement study. The parametric variations considered are: (i) the blowing
ratio is from 0.6 to 1.6; and (ii) two plate materials with lower (0.2 W/m K) and higher (14.9 W/m K) thermal
conductivity. A good agreement of effectiveness distribution on the surface is found between the measured and
the conjugate calculation. The results are explained through various flow features observed: jet lift off, counter
rotating vortex pair, downstream spiral separation node, side spilled vortex interaction, interaction of upstream
and downstream hole in the staggered arrangement, shearing between jet and mainstream etc. In case of lower
conducting material, local patches of higher effectiveness are observed close to jet exit but are found to reduce
with distance. For higher conducting material the effectiveness values are lower but uniform across the plate. A
comparison between film cooling and impingement cum film cooling indicates that the steady state temperature
value for the combined cooling is lower. Besides, due to the inclusion of impingement jet, conduction becomes
dominant and leads to a more uniform plate temperature. Further, it is observed that the fluctuations induced by
the impinging jet are dissipated as it comes out through the film hole.

Title of thesis : Phenomenological Modeling of Multiple-injection Common Rail Direct Injection (CRDI) Diesel
Engines
Thesis abstract : Multiple-injection is known to achieve simultaneous reduction of NOx and soot emissions which
are the major pollutants of diesel engines. However, the simultaneous reduction of NOx and soot requires an
optimal injection schedule suiting an engine load and speed operating conditions. Arriving an optimal injection
schedule through extensive experiments is tedious and expensive and hence an attempt has been made to
develop phenomenological for predicting combustion and emission characteristics of multiple-injection common
rail diesel engines. The detailed physics involved in the spray, mixing, combustion and emission processes of
multiple-injection technique are explored through the model. The model is validated with a wide range of
experimental results. Parametric studies are carried out to analyze the effect of fuel quantities in each pulses and
dwell period between the injection pulses on combustion, NOx and soot particulate emissions and specific fuel
consumption.

Title of thesis : RETRIEVAL OF GEO-PHYSICAL PARAMETERS FROM MICROWAVE RADIANCES
Thesis abstract : Developing algorithms for retrieval of geo-physical parameters (vertical cloud and rain
structure) from remote measurements of microwave radiances emerging out of a raining atmosphere was
considered as the research goal for my Ph.D thesis. Estimation of rain rate from the retrieved vertical rain
structure as well as its prediction from numerical weather models that assimilate radiances from satellites is
critical for agrarian economies like India. The estimation of surface rain rate will also help in forecasting flood and
other related natural calamities, which can help save several thousands of humans and live stocks from drowning.
The numerical weather research and forecast (WRF) model generated thermodynamic and atmospheric
parameters are simulated for various cyclone events originated in north Indian Ocean region. These parameters
are fed as input to the in-house FORTRAN code that simulates brightness temperatures in the microwave region
as output. The WRF model generated input, the in-house model simulated brightness temperatures and observed
microwave brightness temperatures from a space borne radiometer are judiciously combined in a Bayesian
framework to retrieve a three dimensional cloud and rain structure of the earth’s raining atmosphere.

Title of thesis : Studies on Cooling of Discrete Heated Elements in an Application to Electronic Cooling Industries
Thesis abstract : The main objective is to find the optimal distribution of discrete heat sources (Aluminum)
mounted on a substrate board (Bakelite) loosing heat by convection, and radiation. The discrete heat sources are
the individual heated elements mounted on the mother board of a computer, or on the printed circuit board (PCB)
of any electronic devices. For the present case the PCB (Actually made of FR4) is mimicked by a low thermal
conductivity material, Bakelite, and the chips or heat sources mounted on the PCB (Actually made of Silicon) are
by Aluminum. The optimal configuration is one for which the maximum temperature excess among heat sources
(temperature difference between the heat sources, and ambient) is minimum among all other possible
configurations, which is determined by a non-dimensional geometric parameter '?'. Experiments have been
conducted for both square (identical), and rectangular (non-identical) protruding discrete heat sources, which are
five in number, subjected to uniform heat flux, under natural and mixed convection heat transfer. The effect of
surface radiation on these heat sources has been studied by painting them with black paint. It has been found
that, radiation plays an important role for the cooling of discrete heated elements, as there is a temperature drop
upto 15%, which helps in better cooling. The number of possible configurations for arrangement of both square,
and rectangular heat sources on substrate board is determined by a MatLab programme. Experiments have been
conducted for some of the configurations (choosen on the basis of '?' value) at different power levels and for
polished and black painted surfaces. These experimental data are used as a forward model to Artificial Neural
Network (ANN), which is then coupled with Genetic Algorithm (GA) to determine the global optimal position of
discrete heat sources, for which the maximum temperature excess is minimum among all possible configurations
of heat sources. This optimal configuration is then experimentally validated, and it has been found that, the
maximum temperature excess in both the cases agree with each other with an error band of 1.5%. Flow
visualization study has been carried out by using Schlieren and Shadowgraphy technique,to study the interaction
between discrete heat sources. This whole idea suggests some guidelines for the design of electronic devices,
and helps in better thermal management.

Title of thesis : NOX REDUCTION IN BIO-DIESEL FUELED COMPRESSION IGNITION (CI) ENGINE
Thesis abstract : Biodiesel has been receiving considerable attention for its potential use as an alternative fuel to
petroleum diesel. The properties of biodiesel are close to the petroleum diesel and its use in diesel engines
provide significant reduction in particulates and to some extent of unburned hydrocarbon, carbon monoxide and
net carbon dioxide emissions. The biodiesel fuels, however, have a cold flow characteristics, lower heating value,
lower storage stability, some what poor atomization due to slightly higher viscosity and higher emissions of
nitrogen oxides (NOx)]. The increased NO emission from biodiesel fuels restrict their widespread use, as the NOx
emissions lead to the formation of ozone and photochemical smog when reacting with hydrocarbons in the
presence of sunlight. The realization of these severe effects of engine exhausts NOx emissions brought the
aspects of understanding the biodiesel-NOx penalty and NOx emission control to the forefront and drives the
changes in biodiesel fuelled CI engines. The present research work envisages an experimental investigation on
biodiesel operation of the engine for determining an appropriate injection timing and exhaust gas recirculation to
provide the required engine performance and emission levels.

Title of thesis : Computational micro mechanics of composite materials
Thesis abstract : Computational micro mechanics plays an important role in the research of advance engineering
material such as composites. Representative volume element (RVE) approach is used to predict the elastic
properties as well as the local distribution of the stress associated with in the fiber reinforced composites. The
accuracy of prediction of stress in the micro level depends on accuracy of the local morphology of the micro
structure. Nearest Neighbour algorithm (NNA) is used to generate the random fiber in a RVE. ABAQUS is used to
simulate macro mechanical and micro mechanical behavior of composite materials. The main objective of
simulation is to predict the mechanical properties of the composite material and to predict the probability of

Title of thesis : Identification of Elastic Constants of Composite Plate Using Response surface methodology
Thesis abstract : The purpose of this work is to obtain the elastic constants of composite material by analyzing
its dynamic response. Thin orthotropic plate was taken and its response for the impact force was observed in both
time and frequency domain. Finite element model that reflects the actual system properties are developed. The
response of the system for an initial range of input values was predicted using the finite element model. The
difference between the experimentally measured and theoretically predicted responses is counted as error. The
error is minimized by updating finite element model. The procedure is applied to the plate bending problems and
the experiments are simulated numerically with known parameters of the material

Thesis abstract : Noise levels in urban aresa are touching peak levels due to high traffic density. Its no wonder to
say that the contribution of tire is about 30% on the whole noise produced by the vehicle. So, its very important to
study the noise emission mechanisms in deterministic manner. Tire noise is broadly divided into two types, Air
borne noise and Structure borne noise. we are mainly concentrating on influence of factors viz.., inflation
pressure, static preload, temperature, rolling speed etc. on the tire acoustic cavity. For this we are modelling and
analyzing tire with air using ABAQUS .

Title of thesis : Studies on the influence of axial bends on low frequency ultrasonic guided waves in hollow
cylinders (pipes)
Thesis abstract : Ultrasonic guided waves in hollow cylinders (pipes) are today widely applied as rapid screening
tools in the inspection of straight pipe segments in oil, power generation and petrochemical processing industries.
However, the characteristics of guided wave propagation across features such as bends in the pipe network are
complicated, hampering a wider application of the developed techniques. Although a growing number of studies in
recent years have considered guided wave propagation across elbows and U-type bends, the topic is still not very
well understood for a general bend angle ?, mean bend radius R and pipe thickness b.The objective of this work is
to study the influence of axial bends on low frequency ultrasonic guided waves in hollow cylinders (pipes). Here
we use 3D Finite Element (FE) simulation to illumine the propagation of fundamental guided pipe modes across
bends of several different angles ?. Also the reflection and transmission characteristics of bends were studied, in
order to differentiate them from effect due to possible defect in the bend region. FE models were validated
through experiments and analysis.

Title of thesis : Experimental and Computational Conjugate Heat Transfer Study on a Gas Turbine Inlet Guide
Vane in a Linear Cascade
Thesis abstract : Heat Tansfer in Gas Turbines has been a topic of wide discussions and research for the past
three decades. To increase the efficiency, as there is a tendency to increase the inlet temperature of a gas
turbine, reduction of thermal loads and maintain turbine blades at a safer temperatire limit is a necessity. Various
cooling schemes, external (Film cooling) and internal (Convective, Impingement cooling), are widely used and
studied. While most of the previous studies are done under adiabatic condition and concentrating on individual
cooling schemes, the objective of the work is to conduct the study with multiple cooling schemes for a realistic
turbine blade under conjugate condition where conduction is considered and flow & heat transfer is coupled.
Experiment is done on the laboratory linear cascade wind tunnel. A refrigeration system is designed to supply
secondary cold air. Infrared thermography technique is used for temperature measurement. The effectiveness of
cooling schemes under various blowing ratios is studied. Computational work is carried out in Ansys-Fluent.

Title of thesis : Burn Rate Analysis of Multiple-injection Common Rail Direct Injection (CRDI) Diesel Engine
Thesis abstract : The advantages of multiple injections have been well demonstrated by experimental
investigations and modelling results that are reported in literature. A control system however requires a simple
empirical model rather against complex CFD models and in this regard development of an empirical model for a
common rail engine has been envisaged. The approach of empirical modelling used is the Wiebe type burn rate
law to describe the fraction of energy released in a cycle. The following points briefly provide an idea of the entire
process: Experimental pressure histories are acquired on a FORD common rail engine and are processed for
obtaining ignition delay, energy release and combustion duration Correlations are formulated to predict the
ignition delay and combustion duration obtained in the previous step The energy release information is used to
extract burn fractions at the different operating conditions The Wiebe curve is fitted for these burn fraction profiles
obtained previously and the constants appearing in the equation are correlated with engine operating conditions

Title of thesis : Experimental and Analytical study of Particle Damping
Thesis abstract : Particle or impact damping technology is one of the latest techniques being used in vibration
and noise attenuation applications. It is a passive vibration damping approach wherein metallic or non-metallic
particles in spherical form are placed inside cavities or attached to structures by an appropriate means at strategic
locations, to absorb vibration energy. The inherent advantages over conventional damping methods include
fitness at extreme low or high temperatures and applicability over wide frequency ranges. In the present work
particle dampers are tested experimentally on simple aluminum cantilever beam for vibration attenuation. The
particles are embedded inside cavities at the anti-nodes of first, second and third bending modes. The success of
this preliminary work has lead to the application of particle dampers in honeycomb structures. Here, Finite
element method (FEM) is used to predict the flexural dynamic behavior i.e., natural frequencies and mode shapes
of the aluminum honeycomb plate by doing a structural modal and harmonic response analysis simulation. The
results are validated by an experimental transient impact modal test on hexagonal aluminum honeycomb
specimen in free-free condition. Next, particle damping in the form of stainless-steel spheres of varying sizes viz.
0.8mm;1mm and 2mm is applied at appropriate locations to study the influence of particle sizes and volumetric
packing ratios on first, second and third bending modes of a honeycomb panel subjected transient impact modal
test. The Frequency Response Functions (FRF) are acquired and measured using Smart Office Spectrum
Analyzer Software. The frequency shift, response attenuation attained and damping factors are experimentally
found out and compared with baseline measurements It has been found out that particle damping leads to
substantial reduction in vibration amplitudes over first few modes. The more the packing fraction, the more is the
attenuation attained. Results also confirm the non-linear behavior of particle dampers whose efficiency is affected
by the quantum of excitation forces and density of particles distribution. An optimum is reached for the best
damping efficiency for a particular bending mode. In order to simulate the granular motion of the spherical
particles in cavities, MSC.ADAMS codes are executed .To get an insight into particle-particle and particle-wall
interactions from computational multi-body dynamics point of view, spring-dashpot models are constructed. The
motions are evaluated in time and frequency domain and responses calculated. Generally, particle motion is
widely studied using Discrete Element Method (DEM). To analyze the granular motion from computational
molecular dynamics point of view PFC 3D (Particle Flow Code) are run and particle motion is visualized to get a
better appreciation into the granular flow of particulate assembly inside cavity.

Title of thesis : COMPUTATIONAL ANALYSIS OF RECESS VANE GEOMETRY MODIFICATION IN THE
CASING TREATMENT APPROACH TO ENHANCE STALL MARGIN IN AXIAL FLOW FANS
Thesis abstract : Different casing treatment methods exist to improve the operational range of an axial flow fan.
Recess vane casing treatment constitutes one of these approaches. In this approach a circumferential recess with
vanes around the casing is employed for stall margin enhancement. The flow at the tip of the axial flow fan is
allowed to enter through an opening into the recess and de-swirled by the vane and redirected into the main
passage of the fan. This redirection of the flow will remove the re-circulating flow near the fan tip inlet. Present
study concerns modifications to the recess vane geometry to allow for additional enhancement of the fan
operating range. Numerical simulations of the effect of variation of the axial blade chord exposure and provision of
different recess height for each exposure, vane count and Vane curvature is the subject matter of this study. The
sensitivity of the operating range to the modifications is analyzed and the most important recess vane geometry
parameters are evaluated. Improvements to the stall margin are obtained with some of the modifications to the
recess vane geometry.

Title of thesis : Mathematical modeling and finite element simulation for fatigue crack prediction in flat/curved
plates using Tone-Burst Eddy current Thermography (TBET)
Thesis abstract : Tone Burst Eddy Current Thermography (TBET) technique is a new hybrid, non-contact, NonDestructive Evaluation (NDT) method which employs a combination of both Eddy Current Testing (ECT) and
Thermographic Non-destructive testing (TNDT) techniques. It is a widely used NDT technique for the analysis and
detection of fatigue induced cracks, corrosion induced pits etc, which occurs common in aircrafts. The study
focuses on the mathematical modelling and FE simulation (using FEA package Comsol 4.2a) of typical flat and
curved aircraft components under fatigue loading, for the prediction of stress induced cracks using TBET. This
technique uses induced eddy currents to heat the material being tested and the defect detection is based on
changes of the induced eddy current flows which is revealed through thermal visualization captured by an infrared
(IR) camera. For understanding the influence of cracking and pitting on heat generation and flow within a metallic
body, a fundamental knowledge of the detailed induced current density distribution in the component under test is
required. This information enables us to calculate the amount of heat produced by the defects and how that heat
diffuses to the surface where it is imaged. The objective of this work is to determine whether the TBET method is
suitable for the detection and characterization of service induced cracks, usually caused by either rolling contact
fatigue or stress corrosion, with a high degree of sensitivity.

Title of thesis : "Application of Ultrasonic Atomization to SI Engine"
Thesis abstract : Ultrasonic atomization is a very convenient method to produce very small droplets of fuel.
Resulting droplet size distributions are very narrow and the mean diameter is essentially only controlled by the
excitation frequency. Generation of droplets in the micron range can be achieved 130-140 kHz waves, with
voltages of around 15-30 V. To explore the capabilities of ultrasonic atomization for combustion in an internal
combustion engine, an excitation source i.e. ultrasonic atomizing micro-nozzle has been used. This ultrasonic
atomizer is made of piezoelectric ceramic material. The flow rate with different pulse width at same frequency is
found out., and it will further be used in combustion application of a small two wheeler internal combustion engine
(110 cc) to determine its performance and emission.

Title of thesis : EFFECT OF FLOW INDUCED VIBRATION ON FLUID STRUCTURE INTERACTION
Thesis abstract : Flow-induced vibration (FIV) is a typical fluid-structure interaction problem. For example flow
over automobiles, buildings, bridges, risers etc. The presence of bluff body (say square cylinder) in a flow alters
the dynamics of the flow. When Reynolds number is sufficient it initiate vortex shedding from body. These vortices
that are shed from the body will impart oscillatory forces on the body and make the body to vibrate and further
may lead to the failure of the structure. Hence FIV has became an important area of research. FIV can also be
studied by forcing the cylinder to vibrate using external source which is typically known as forced vibrations. The
response of unsteady wake, aerodynamic forces, lock-in behavior etc. due to the presence of a single cylinder
and combination of cylinders at different arrangements are studied numerically. Computations are performed
using a developed Finite difference code using MAC algorithm and also using the commercial Finite volume
software Fluent.

Title of thesis : Modal analysis of Ultrasonic Guided Waves for inspection of Structures with arbitrary crosssection using Semi Analytical Finite Element (SAFE) Method
Thesis abstract : Ultrasonic guided waves are attractive for the long range inspection of large structure due to
their unique features such as high velocity, through structure penetration and low attenuation in uncoated
components. They are well established in the inspection of straight regular large structures with simple crosssection like plate; pipelines etc.To extracting the modal structures and understand the behavior of guided waves
in irregular cross-sections is still often not known. So, we demonstrated the Semi-Analytical Finite Element
(SAFE) Method to understand the modal structures in complex cross section. Recently the SAFE method has
been widely used for such applications. The advantage of this method is that only the cross section of the wave
guide has to be meshed by finite element i.e. the section normal to the direction of wave propagation.This
significantly reduces the computational time and can be used to model large geomtries.we described solutions to
dispersion curves and modal structures achieved using the SAFE method for complex geometries such as
transverse bend plate ,Oval pipe, Eccentric pipe and polygonal pipe, which has a broad application in a number of
industries and it will be more useful for practical NDE inspection.

Title of thesis : Condition monitoring of Marine diesel engines using Acoustic Emission
Thesis abstract : In reciprocating machinery like IC Engines, due to the amount of power involved during the
motion of the piston inside the cylinder, proper lubrication of the cylinder liner is critical. Lack of sufficient
lubrication inside the cylinder can lead to a wide range of problems to the engine including power loss, excessive
fuel consumption and in more serious cases, scuffing and damage to the liner and rings. Thus the monitoring of
the lubricant oil supply to the cylinder is essential in achieving better efficiency for the engine in terms of power,
fuel consumption etc. The objective of the work is to use acoustic emission signals for evaluating the
effectiveness of lubrication inside the cylinder. Tests were conducted on different kinds of engines to study the
relationship between the lubricant oil level and the frequency content of acoustic emission (AE) signals. Further
the changes in the AE signal were studied quantitatively to prove its effectiveness as a tool to monitor lubricant oil
level.

Title of thesis : Studies on ultrafine grained magnesium based materials processed by severe plastic deformation
techniques for biomaterial applications
Thesis abstract : Magnesium and its alloys have attracted great interest in the field of biomaterials due to their
degradable nature in physiological environment and mechanical properties near to natural bone. However,
controlling the rapid degradation is prime issue need to be addressed in developing biodegradable implants based
on magnesium biocorrosion. Severe plastic deformation techniques attracted great attention due to the potential
to achieve nano-submicron grain structures in solid state itself. Equal channel angular pressing (ECAP),
accumulated roll bonding (ARB), high pressure torsion (HPT), friction stir processing (FSP) and groove pressing
(GP) are the processes developed to refine the microstructure of metals. In the preset work, pure magnesium and
AZ31 magnesium alloys were processed by ECAP, GP and FSP to achieve fine grain structure. The role of
microstructure on the degradation rate, biomineralization and cell response was studied. ECAP was adopted for
solid samples of rod shape of diameter 6mm and 10mm. GP was adopted for processing sheets of thickness
2mm. FSP was used to refine the microstructure at the surface and to prepare the surface composites using nanohydroxyapatite as the dispersing phase. Also, magnesium and hydroxayaptite composites were fabricated from
high energy ball milling and sintering. All the materials processed by different routes are investigated in-vitro to
evaluate the toxicity levels and material tissue interactions.

Title of thesis : Enhanced surface properties and electrochemical durability of multistage PTFE treated gas
diffusion layers for proton exchange membrane fuel cells
Thesis abstract : The main objective of research is to study the degradation of carbon based gas diffusion layers
of Proton Exchange Membrane fuel cells and to study the impact of aging on material properties under PEM fuel
cell conditions. Degradation of the GDLs is studied in terms of surface chemistry changes due to formation of
strong functional carbon oxides such as carboxyl which makes surface of the GDL wettable. Hydrophobicity of
GDL is lost during the course of the operation of PEM fuel cell which causes flooding inside the cell resulting in
mass transfer issues. The present study compares the degradation of GDL by electrochemical and chemical
aging under simulated PEM fuel cell conditions in terms of hydrophobicity loss. Corrosion rate of GDLs are
studied by potentiostatic aging response and the extent of electrochemical oxidation is understood from
potentiodynamic (Cyclic voltammetry) analysis. The surface carbon oxygen functional groups responsible for
increasing the wettability of GDLs are confirmed by X-ray photoelectron spectroscopy (XPS). Hydrophobicity loss
of GDLs is observed by surface contact angle and water uptake measurements. Influence of PTFE treatment on
aging behavior of GDLs is studied and the impact of novel multistage PTFE treatment on the electrochemical
durability of GDLs used in PEM fuel cells is examined. It is observed that it is possible to establish a gradient in
PTFE profile in the GDL by adopting multistage treatment. Such gradients counteract loss in hydrophobicity
resulting from carbon corrosion due to electrochemical aging. The results reveal that GDLs subjected to
multistage PTFE treatment can have increased lifetime as opposed to conventional single stage PTFE treated
GDL.

Title of thesis : Influence of groove pressing on the drawability of AA 5052 sheets.
Thesis abstract : Aluminium alloy sheets have poor drawability compared to steel sheets as indicated by the
values of the plastic strain ratio or the R value (Lankford value). Because of the textures developed during
commercial annealing and cold rolling processes, the R value for aluminium alloys is typically less than 1. Thus
there is a need for processing techniques that enhance R values of aluminium alloy sheets. Since the R value is
heavily influenced by the crystallographic texture in the sheet, processes that develop a favourable texture can be
utilised to improve the R value. In this study, a severe plastic deformation process called groove pressing has
been used to repeatedly deform sheet specimens of aluminium alloy AA 5052. Annealed strip specimens of
dimensions 220 mm x 50 mm and 1 mm thick were cut in three orientations namely 0°, 45° and 90° to the rolling
direction. A set of asymmetrically grooved dies of groove angle 45° were used for groove pressing. The strip
specimens were groove pressed in compression mode and then flattened using the flat dies. The process was
repeated several times to impart large strain to the specimens. The thicknesses of the sheets remain largely
constant after the process. The R values of groove pressed specimens were experimentally determined as per
ASTM standard E 517-00. Tensile testing and micro structural characterization were also carried out. The
changes in the R value are correlated with the variations in the texture.

Title of thesis : Study on semisolid processed Aluminum alloy A356 for joining process
Thesis abstract : Semi-solid Aluminum alloy A356 is tungsten gas arc welded with cooling setup to study
variation in morphology of grains from that of base metal. Semi-solid forming is the process of shaping the metal
in the semi-solid state. As alloys solidify, the primary dendrites normally grow and coalesce with each other such
that, as soon as a relatively small fraction of the melt has frozen, viscosity increases sharply, and flow practically
ceases. In this research, the semi-solid metal (SSM) slurry of Aluminum A356 is prepared by linear
electromagnetic stirring (LEMS) setup in IISC Bangalore. During this process the dendrite growth is suppressed
by agitating the melt during solidification, reasonable fluidity persists and a strong fluid flow detaches the
dendrites formed at the solid-liquid interface and carries them into the mould to form slurry. When this slurry
solidifies, the microstructure is characterized by globular, non-dendritic primary phase particles, separated and
enclosed by a near-eutectic lower-melting secondary phase. Such alloy slurries flow in a laminar manner, which
allows for uniform die filling as opposed to the turbulent flow associated with casting processes. A three
dimensional finite element model SYSWELD is employed to analyze the temperature distributions in the weld
joints. Thermal properties like thermal conductivity, specific heat of aluminum A356, convection and radiation
boundary conditions are considered in the model. The numerical results of the model are utilized to correlate the
solidification substructure formed around the weld pool. The weld profile predicted by numerical analysis is
compared with that of the results obtained through experimentation.

Title of thesis : Study of moored vessel response optimizing moonpool shapes
Thesis abstract : Moonpools are vertical wells onboard vessels like cable-laying vessels and offshore support
vessels. Moonpool gives passage to underwater activities for different types of ships as per their mission
requirements. It is observed that inside a moonpool considerable relative motions may occur, depending on
shape, depth of the moonpool and frequency range of the waves to which the ship is exposed. The vessel
responses are entirely different in zero and non-zero Froude number. Former situation is paid attention in this
study as the mission requirement of the platform is to be in the particular location for long period of operation. It is
well known that there are two modes of responses depending on the shape of the moonpool viz., piston mode and
sloshing mode. Moonpools of square, circular and rectangular shapes with different aspect ratios of opening like
1:1.5 and 1:2 ratios are tested to measure the responses. The vessel moored using heavy lines are modelled and
tested in the wave basin. The different modes of oscillations of water columns are measured using wave gauge
and the vessel response at a particular situation is determined. RAOs determined for various situations provide
better insight to the designer. Comparison, of experiments done in the wave basin, using a well known software
package meant for handling moored floating bodies is presented in this paper. The ambiguities of the result using
the said package programme are eliminated by verifying motion parameters obtained using experimental study.

Title of thesis : Numerical analysis of oscillating water column as a wave energy device.
Thesis abstract : The work investigates the numerical analysis of a novel axi-symmetrical floating structure
working as a wave energy device (WED). Wave energy is a non-polluting and renewable source of energy,
created by natural conversion of part of the wind energy above the oceans. Wave energy device face waves from
all directions and move in all the six-directions in which the heave response provides maximum energy. The
present concept of WED consists of a floater, a tube with larger thickness (TLT) for providing stability and a tube
with smaller thickness (TST) connecting the floater with the TLT (see Fig1). The floating concept of WED is
modelled and analyzed using the finite element software ANSYS-AQWA for power take-off and efficiency in
regular waves. A 100year wave condition is used for the study. The OWC is installed in 100m water depth with a
catenary mooring configuration to keep the structure in position and to allow heave motion only. The wells turbine,
having linear characteristic curves, as a power take-off system is modelled only as a point mass system. This
WED is modelled such that the water is allowed to enter inside the water column through an opening at the
bottom part. The TLT keeps the mean density of WED less than the water. Wave actions cause the WED to
oscillate and then water enters into the water column, compresses the trapped air inside the upper portion of the
water column which acts like a piston. The oscillations of the floater and the water column, apart from the heave,
are restrained. In order to provide the optimal power for design considerations, it is important to make estimates
of the hydrodynamic performance of the OWC under typical operating conditions. A parametric analysis of the
WED with respect to diameter of the floater, submerged length and height of the air chamber is performed in order
to obtain the optimum power extraction. All the above analysis is computed in time domain for a regular wave.
The results bring out the optimized power performance of the WED. Keywords: Floating OWC, wave energy
device, Power extraction, parameter optimization

Thesis abstract : Recent observations of sea state that result in undesirable events confirm the presence of
extreme waves like freak waves which can either cause irreparable damages to offshore installations or create
inoperable conditions and discomfort to the crew onboard. Knowledge on extreme wave environment and related
wave-structure interaction is required for safer design of deep water offshore structures. In the current research,
typical long crested extreme waves namely i) New Year wave at offshore Norway; and ii) Freak wave at North
Sea are simulated using combined wave model. Dynamic response of offshore Tension Leg Platforms (TLP)
under these extreme waves is carried out for different wave approach angles.

environmental loads at ultra-deep waters; the requirement is vital as the oil and gas exploration is heading
towards greater water depths. Triceratop consists of deck structure with a positively buoyant leg structure (BLS)
connected through ball joint. Ball joint transfers only translational motions and restricts all rotational motions.
Offshore triceratops is significantly resistant to rotational motion because of the presence of ball joints between
the BLS units and the deck. Recent studies show that structures with universal joint show significantly lesser
response under the encountered environmental loads. Though seismic loading is not inherent for every offshore
platform due to the significant hydrodynamic damping, it is a mandate to consider seismic loads for extreme
loading conditions. Offshore complaint structures experience significant tether tension variations under the vertical
seismic excitations caused at sea floor. In the present study, time history of such tension variations that are
imposed on tethers by two different vertical seismic forces are considered; platform is subsequently analyzed for
the operational sea state under the changed pretension in the tethers. .

Title of thesis : Dynamic analysis of Floating offshore wind Turbine
Thesis abstract : The 5MW NREL wind turbine (Jonkman 2007) resting at top of a spar floater in water depth of
200m is studied numerically . The wind turbine along with the spar floater is modelled such that they can
withstand harsh wind and wave loading conditions. A 100 year wind and wave condition is taken for the study.
The hydrodynamic analysis is performed using ANSYS-AQWA software (ANSYS AQWA 2010) while the
aerodynamic analysis is done through FAST software (Jonkman 2007). The spar along with the turbine is
modelled as a rigid structure subjected to regular waves. The linearised hydrodynamic wave loading is computed
by using Morison equation. The hydrostatics and stability criteria are checked for the spar. Time domain analysis
is done for parked condition under extreme environmental conditions. The effect of mooring lines attached to the
fairlead point which will provide extra stiffness to the floating platform are also taken into the numerical study. The
motion of the platform is also very important to study that account for the efficient system so Simulations were
carried out to calculate the structural responses for the some regular sea states.

Title of thesis : Design and development of an integrated CAD+CFD model for simulation based ship
hydrodynamic optimization problems
Thesis abstract : Simulation based ship hydrodynamic (SBSH) optimization combines conventional areas of
resistance and propulsion, sea-keeping, maneuvering, and computer aided design (CAD) + computational fluid
dynamics (CFD), and offers a remarkable possibility of the implementation of an integrated design process from
conception to design to production. development of SBSH demands a new paradigm for hydrodynamics research
in which CFD, CAD and CAE are conducted simultaneously for the benchmark geometries and conditions using
an integrated approach along with optimization methods, all of which serve as internal engine guaranteeing
simulation fidelity. In the present paper the fundamental constitutive elements of a SBSH environment are
presented and analyzed. Our focus is on complex engineering optimization problems which involve
computationally expensive objective functions and nonlinear constraints. We discuss advanced strategies to
reduce the overall computational efforts, optimization algorithms for nonlinear programming problems, and
NURBS based CAD techniques for shape variation and mesh manipulation. A simple verification and validation
(V&V) methodology for assessing errors and uncertainties in SBSH is also presented and it is primarily based on
the trends. Finally, we present two different SBSH models and discuss one design problem, i.e., optimal shape
redesign of a ship under real-world geometrical and functional constraints. To access the practicability of the
design, the experimental results of the optimized models are analyzed.

Title of thesis : Hydrodynamic response of perforated cylinders in regular waves and their application in offshore
structures like Tension Leg Platform ( TLP )
Thesis abstract : Experimental and Numerical investigations are carried out on perforated cylinders. it is seen
that the forces on inner cylinder increases with the increase in porosity; however, there is reduction in the forces
on inner cylinder with the decrease in perforation size. Forces on inner cylinder reduce significantly with the
perforated outer cylinder for short period waves compared to that of long period waves. Because of Perforation
there will be reduction in Forces (Due to wave and Current) , reduction in VIV ( Vortex induced vibration ) .Hence
Perforation concept can be used in Offshore (Column of TLP ,Riser and Subsea Pipeline etc.) Experimental
results are validated with commercial CFD software STAR CCM+ A new retrofitting method of TLP members
using perforated outer cylinders; experimental investigations carried out on the scaled model of TLP show
significant reduction in complaint degrees-of-freedom of the platform. Reduction in tether tension is also seen in
such forms which is a derived benefit of stress relief mechanism in the tethers as well.

Title of thesis : Structural, optical and magnetic properties of LnCrO3 (Ln = La, Gd, Dy, Ho, Y and Er)
Thesis abstract : Understanding of functional perovskite-type oxides ABO3 is of active research interest due to
its relevance to both fundamental and application related issues. Perovskite-like metaloxides have a great degree
of tolerance to adopt multitude of different structural distortions as well as coupling between charge, lattice and
magnetic (spin and orbital) degree of freedoms giving rise to extraordinary physical properties such as
ferroelectricity, (anti-) ferromagnetism, multiferroicity, colossal magnetoresistance, electronic and ionic
conductivity, high temperature superconductivity, half-metallicity etc along with wide compositional flexibility. So it
is of considerable importance to understand the coupling between spin, phonon, orbital degrees of freedoms and
underlying phenomenon. In my Thesis work entitled "Structural, optical and magnetic properties of LnCrO3 (Ln =
La, Gd, Dy, Ho, Y and Er)" it has been tried to understand the effect of structural distortions due to different ionic
radii of Ln-site ions in LnCrO3 keeping the crystal symmetry (space group: Pnma) unchanged on their optical and
magnetic properties as well as the coupling between different degrees of freedom like phonon, spin, orbital and
charge. We observe that predominent magnetic ordering is antiferromagnetic where ordering temperature (TN)
followes only orthorhombicity of unit cell and not on the magnetic moment on Ln-site ions while next-nearestneighbour interection depends on Ln-site magnetic moments. LaCrO3 shows optical phonon and dielectric
anamaly at antiferromagnetic transtion temperature confirming magnetoelectric coupling.

Title of thesis : Structural and optical properties of nano ink based CIGS and CZTS thin films for Photovoltaic
applications
Thesis abstract : Do all the single crystalline materials show better photovoltaic performance compared to their
polycrystalline counterparts? No. Grain boundries act as recombintion centers. As grain boundaries number
increase the photovoltaic performance decreases. But this is NOT ALL. There are certain class of materials,
chalcopyrites (CdTe, CIS, CIGS) which show better photovoltaic performance in their polycrystalline form.
Chalcopyites have unique grain boundary physics, where in the grain boundaries are electrically benign. This
reduces the rate of recombination, improves open circuit volage and hence phhotovoltaic performance. In, Ga in
CIGS are either less abundant or very expensive. So replacing In, Ga with Sn, Zn (which are relatively more
abundant and inexpensive) we realize a new chalcopyrite material CZTS with a direct band gap of 1.5 eV.
CIGS solar cells show a lab level efficiency of 20.5% (Co-sputtering). CZTS synthesized by chemical routes
show better performance (10%), compared to CZTS films grown by vacuum techniques. If CZTS has to
completely replace CIGS it has to demonstrate all the properties of CIGS including unique defect physics. My
research includes: Synthesis of CIGS and CZTS nano ink by hot-injection technique and deposition of thin films. Xray diffraction and Raman studies for phase identification TEM, SEM-EDAX studies for structural ,morphological
and compostion analysis. Scannig Probe microscopy (Conductive Atomic Force Microscopy, Electro Static Force
Microscopy) to understand grain boundary physics in CZTS Growth and characterization of CdS, ZnO thin films
by Chemical Bath Depositin (CBD) and sputtering respectively for electrical properties study and device
fabrication.

About me :
Let there be light ......
Let there be electricity.....
Let there be electricity from light !
Guess what ?...............if your guess is solar cells it is correct.! I work on thin films for photovoltaic applications. Xray diffraction, Raman spectroscopy, Electron microscopy/diffraction, Scanning probe micrscopy coupled with thin
film deposition techniques are bread and butter of my research routine.
I believe in "Independent thinking and collective working. Research
should bring out innovative ideas which should pave a way for business venture which on a large scale should
generate employment as well as improve the technological acquaintance of a nation, add to the skilled work force
and in the long run boost the economy of the nation". I would like to be an integral part of a team/organization with
such a mission and vision and contribute myself to the team work.
