OPTIMAL APPROXIMATION IN HENSELIAN FIELDS
Asim Naseem, Khurram Shabbir, *Shahid Ahmad, Aansa Islam
ABSTRACT: A non-empty subset S of a valued field K is said to have the optimal approximation property if every element in
the field K has a closest approximation in S. This property relates to the model theory of valued fields, which was introduced by
F.V. Kuhlmann in [1]. The notion becomes more involved when the set S is the image of a polynomial map on K. In this paper, we
present some classes of polynomials over a henselian discretely valued field, whose image set has optimal approximation
property.

Fatima Zulfiqar1,i and *Sakander Hayat
ABSTRACT. A direct interconnection network (IN) of a multiprocessor system is represented by a connected graph whose
vertices represent processing nodes and edges represent communication links. A processing node (PN) usually consists of one or
more processors, local memory, and communication router.
The butterfly and Benes networks are important class of multistage direct interconnection networks which are defined based on
n
the schemes that connect the units of a multiprocessing system and needs n stages to connect 2 processors; at each stage a
switch is thrown, depending on a particular bit in the addresses of the processors being connected. In this paper, degree based
topological indices of these direct interconnection networks are strong-minded.

ABSTRACT: One of the discussions of data envelopment analysis (DEA) is the returns to scale. Regarding the fact that in the
real life issue we usually face undetermined data, the study of phenomena with determined data does not seem rational. In this
regard, considering the data as interval has special importance. Therefore, the purpose of this study is to extend the methods of
determining the types of left and right returns to scales in DEA into inexact interval concepts. In this study, we extend the
represented models by Eslami and Khoveyni [1] in determining the types of left and right returns to scales at the presence of the
Interval Data. First the efficient units are evaluated in pessimistic and optimistic situations. Then we determine the types of left
and right returns to scales at the two situations on the efficient units. Finally an example is provided to further explain the
method

ABSTRACT The concept of interval-valued fuzzy set is one of the most important and useful generalisation of Zadeh's fuzzy sets
which is successfully applied by engineers and scientists in the field of Robotics, Control Theory and Computer Engineering. In
this paper, we introduce new and useful generalisations of interval-valued interior ideals and interval-valued fuzzy left (right)
ideals called interval-valued (~ ,~ q ~ ) -fuzzy interior ideals, interval-valued (~ ,~ q ~ ) -fuzzy left (right) ideals, intervalvalued (~ , ~  q~ ) -fuzzy interior ideals and interval-valued (~ , ~  q~ ) -fuzzy left (right) ideals of ordered semigroups.
These newly defined concepts are supported by suitable examples, and several fundamental results are investigated. It is shown
that in regular and semisimple ordered semigroups, both the concepts of interval-valued (~ ,~ q ~ ) -fuzzy interior ideals and
interval-valued (~ ,~ q ~ ) -fuzzy ideals coincide. Further, the relation between interval-valued fuzzy interior ideals and
interval-valued fuzzy ideal of type (~ ,~ q ~ ) is provided

ABSTRACT: A glued graph at complete clone is obtained from combining two graphs by identifying edges
of of each original graph. We investigate how to change some properties such as height, big height, Krull dimension, Betti
numbers by gluing of two graphs at complete clone. We give a sufficient and necessary condition so that the glued graph of two
Cohen-Macaulay chordal graphs at complete clone is a Cohen-Macaulay graph. Moreover, we present the conditions that the
edge ideal of gluing of two graphs at complete clone has linear resolution whenever the edge ideals of original graphs have
linear resolution. We show when gluing of two independence complexes, line graphs, complement graphs can be expressed as
independence complex, line graph and complement of gluing of two graphs.

ABSTRACT; Mathematical modeling of drug diffusion system is a strenuous task due to the heterogeneous structure of
mammalian cell. The difficulty level increases when the lipophilic compounds are taken into account. Earlier, 1D spherical
shaped cell model was developed by considering spherical symmetry and further this model has been extended by adding nuclear
envelope. In this paper 2D axi symmetric mathematical model is developed with non-spherical cellular geometry by inclusion of
nuclear envelope that is very close to the real cellular geometry of cultured adherent cell used for in vitro experimental results.
Homogenization techniques are used to reduce the complexity of cytoplasm. The numerical results obtained from non-spherical
model are ratified against the in vitro experimental results.

ABSTRACT: Linear model is an integral part in every field and stability of these models relates to the various parameters
involved in the model. The objective of this research is to investigate the stability of linear models. The estimated values of the
parameters of linear models have been obtained through ordinary least squares (OLS) method and their stability is analyzed by
Recursive test. We have investigated the stability of linear models based on the structural changes when the number of
observations is small. The point where structural change occurs is a key point. So when prior knowledge, where the change
occur is not available then recursive least square and recursive residual test have been used.

ABSTRACT: A non-isolated interleaved boost converter with coupled inductors and switched-capacitor circuits is presented in
this paper, which can be employed for renewable energy conversion systems including the photovoltaic (PV) and the fuel cell
(FC). Whereas the voltage generated by these sources is low, a converter with high voltage conversion ratio is the main
requirement for connection to a relatively high dc-bus voltage. To obviate this necessity, a switched-capacitor circuit is
magnetically connected to interleaved boost converter, which effectively increases the voltage growth and decreases the voltage
stress in the semiconductor components, and thereby, the conduction losses are diminished. In fact, the proposed
converter operates as a flyback converter in some times and forward converter in other times. To restrain the leakage energy of
the coupled inductors and confine the voltage spikes on the main switches, the active clamp technique is employed. Furthermore,
the zero voltage switching (ZVS) operation is guaranteed even in the light load, which leads to degradation of the switching
losses. Also, the leakage inductance of the coupled inductors is handled to realize zero-current-switching (ZCS) performance of
the diodes. At last, a 1-kW prototype is implemented to confirm the theoretical analysis and performance of
the proposed topology.

ABSTRACT: In a power distribution system, physical contact between the phase conductors and their surrounding objects such
as trees and buildings is a probable incident. Known as High Impedance Fault (HIF), this situation may lead to fatal ignition or
electric shock caused by the arcing. Although short circuit situations can be recognized by the usual relays in power distribution
systems, HIF incidents cannot be detected easily by the common protection equipment. Since HIF increases the load current very
slightly, it may be misdiagnosed as a usual overload. Therefore, HIF detection is a challenging issue in power distribution
systems. The first step to overcome this problem is finding an appropriate model for the HIF arcing. In this paper, different types
of HIF models are studied and then a complete model along with its simulation method is provided. Afterwards, an ADALINEbased algorithm for HIF detection in power distribution networks is proposed which uses a new harmonic criterion. Unlike the
various solutions already presented for HIF detecting, the proposed approach is very simple and its online implementation is not
problematic. Furthermore, a typical distribution network in the presence of Distributed Generation (DG) resources is simulated
through the EMTPWorks environment. Simulation results verify the accuracy and the quickness of the proposed approach

Abstract: The aim of this paper is to present an improved algorithm to solve harmonic load flow problem in balanced radial
distribution systems with laterals, which have nonlinear load. The method is efficient and easy to implement. This method is
iterative and allows the evaluation of both, voltage (rms) values and phase angles of the fundamental voltage and harmonic
voltage for each bus. The proposed method in this paper can be solved harmonic load flow problem iteratively from two sets of
recursive equations. The first set concern the determination of the branches current by going up the line (backward sweep). The
second one allows us to determine the nodes voltage by going down the line (forward sweep). The total harmonic distortion can
also be calculated easily.

ABSTRACT: Microgrid is a new technology in power generation and this system is used to provide power and heat to its local
area, such as cogeneration systems and renewable energy (wind turbines, photovoltaic cells, etc.). They are preferred for
medium or high power applications. Nanogrid most likely to be used in small local loads for rural area as they will be more
economic then the normal grid power system. Nano grids can operate independently or be connected to the mains and most likely
the internal voltage can be utilized as ac or dc. In this research paper a small scale microgrid system is proposed for smart
homes called "Nanogrid". Each houses have small electrical power system from them can be shared among houses. If it uses a
DC system instead of a general AC system, it can reduce energy loss of inverter because each generator doesn’t need an inverter.
Furthermore, it can continue to provide a power supply when blackout occurs in the bulk power system. A model of a nanogrid is
developed to simulate the operation of the centralized power control. Finally a Simulink model is presented for small houses
power range 90-285 KW.

ABSTRACT— After the emergence of alternative current networks and their popularity, asynchronous motors became more
widespread than other kinds of industrial motors. In order to control and run these motors efficiently, an accurate estimation of
motor parameters is needed. There are different methods to obtain these parameters such as rotor locked test, no load test, DC
test, analytical methods, and so on. The most common drawback of these methods is their inaccuracy in the estimation of some
motor parameters. In order to remove this concern, a novel method for parameter estimation of induction motors using particle
swarm optimization (PSO) algorithm is proposed. In the proposed method, transient state of motor is used for parameter
estimation. Comparison of the simulation results pertained to the PSO algorithm with other available methods justifies the
effectiveness of the proposed method.

ABSTRACT: Modulation classification plays a key role in demodulation of the received signal for extracting the required
information. Modulation classification is a difficult task when there is no information about the received signal (Blind
Classification) and especially in presence of multipath fading and white guassian noise. Emerging applications of automatic
modulation classification (AMC) in military, civil and cognitive radio (CR) applications leads to the development of various
AMC algorithms. The Automatic modulation classification can be achieved by two major approaches, Likelihood based and
features based pattern classification approach. In this paper first we have analyze and discourse the merits and demerits of both
categories, then we have proposed an algorithm based on spectral features of the modulated signal. The proposed classifier is
Multilayer perceptron which is also referred as feed forward back propagation neural network. The channels considered
throughout the simulations are additive white guassian noise (AWGN) channel, Rayleigh flat fading and Rician flat fading
channel. The considered modulation formats are PAM 2 to 64, PSK 2 to 64, FSK 2 to 64 and QAM 2 to 64. The proposed
algorithm will recognize the considered modulation formats with 100% success at 0dB SNR. Tables in the form of confusion
matrix and graphs shows correct classification rate for considered modulation formats.

Abstract: In this paper, optimum design of PID controller for speed control of permanent magnet synchronous motor is
presented using dynamic particle swarm optimization algorithm. Controller design is achieved through a model of motor with the
aid of field-oriented control with linear system. Dynamic particle swarm optimization algorithm can optimally tune the PID
factors and provide an optimum controller. As a result, performance characteristics of system step response such as overshoot,
rise time and settling time will reduce in PMSM and this performance improvement is investigated in MATLAB. The obtained
results show optimum behavior of the proposed method comparing with Genetic Algorithm optimization of PID factors tuning for
field-oriented control of PMSM.

ABSTRACT: Sedimentation remains a major problem in reservoirs which not only lessens the useful life of the reservoir but also
causes abrasion of turbine units; when the sediment loaded water finds its way into the power house. Sand trap is the major
hydraulic structure constructed at the inlet of flow diversion structure in order to trap the sediment to alleviate the abrasion of
turbine units. Role of sand trap chambers for small hydropower projects like Golen Gol Hydropower Project to exclude sediment
is very significant. To analyze the efficiency of the Sand Trap Chamber in the Golen Gol Hydropower Project; NETNUS
Numerical Simulation alongwith MATLAB and AutoCad Softwares was used to assess the effectiveness of the Sand Trap chamber
by computing sedimentation load (tons), longitudinal sedimentation thickness (meters) and finally to propose an operational
mode of operation for sediment flushing by considering two different scenarios i.e. 1) in which all three chambers in running
state and 2) in which only two chambers were operated with varying sediment concentrations i.e. 0.1 kg/m3, 0.2 kg/m3,0.3
kg/m3, 0.4 kg/m3, 0.5 kg/m3 and 0.75 kg/m3 and 1 kg/m3. Results of Scenario-1 indicates that power units can safely operate for
21 days without any stoppage to flush sedimentation in the sand trap when the diversion flow carries sediment concentration of
0.1 kg/m3, but the power units have to shutdown in order to flush out the sedimentation from the sand trap chamber just after 3
days in case when the diversion flow carries sediment concentration of 1.0 kg/m3. Results of Scenario-2 indicates that power
units can safely operate for one and a half day when the diversion flow carries sediment concentration of 0.1 kg/m3, but the
power units have to shutdown in order to flush out the sedimentation from the sand trap chamber in less than a day, when the
diversion flow carries sediment concentration of 1.0 kg/m3.

ABSTRACT: Task scheduling problem in cloud computing has become an active research topic due to the tremendous growth in
the use of cloud computing. Cloud computing is a heterogeneous system and it holds and processes large amount of complex
data. Scheduling tasks efficiently can lead to better performance and more throughputs in the system. In this paper in order to
minimize the cost of processing time, a firefly scheduling algorithm is proposed to schedule tasks in cloud computing
environments. Firefly algorithm is a metaheuristic algorithm, inspired by the flashing behavior of fireflies. We considered two
costs for each task: communication and computation. A comparison is made between proposed algorithm and particle swarm
optimization algorithm in task scheduling. Experimental results show that firefly task scheduling algorithm is more suitable to
cloud computing.

ABSTRACT: Prediction of 28 days compressive strength of concrete using early age strength value is the primary objective of
the experimental study reported in this paper. In most of the cases, accelerated curing method is a requisite to determine early
age mechanical properties of concrete. A simplified accelerated curing method similar to boiling method as described in ASTM
C 684-74 is developed and described in this paper. Concrete used in this work was made using locally available materials in
Pakistan. Concrete cylinders cured by using proposed accelerated method and normal curing method were tested for
compressive strength at early age (28.5h) and at 7 & 28 days of age. Based on the results obtained, 7-D and 28-D strength
prediction relationships have been proposed. Testing of proposed relationships showed satisfactory results.

ABSTRACT- The size of current web is increasing day-by-day at exponential rate and has created difficulties for the users to
access precise and specific information. Although Information on the current web is accessible through computers but only
understandable to human beings. Semantic Web is a response to this problem the idea of which was coined by the original
creator of the web, Tim-Berners-Lee. This future web aims to attach metadata to web resources in a format that makes web
contents machine-processable. Resource Description Framework (RDF) and Topic Maps are the two prominent standards of
Semantic Web developed for machine processing of web contents. These two standards can effectively create metadata
relationship among web contents. Applications are necessary to embed semantic structure in the current web in a manner to
implement the vision of Semantic Web into reality. Applications based on RDF and Topic Maps can store and organize
knowledge in a better way and manage large repositories in an efficient manner. Moreover, applications which never existed
before, and had extraordinary functions that superseded their competitors, are called killer applications. In this paper, we are
aimed to present a comprehensive survey of the available applications, determine the similarities and differences among them.
We also investigated the main reason due to which RDF and Topic Maps have not come to the main stream market yet. It is
concluded that a Lack of killer application is the prominent factor effecting the wide spread use of RDF and Topic Maps.

ABSTRACT –Electricity crisis in Pakistan is mounting day by day. From 2007 onwards, Businesses and consumers alike wonder
each year if there will be enough electricity to go around. It continues throughout the year but the period of concern, referred to
as times of ―peak electric load‖, is a real threat as the demand for electricity exceeds the supply. Results are blackouts, crippling
businesses and household activities within a sector, city, state, and unquestionably in entire region. Load management is the
process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather
than the power station output. This can be achieved by direct intervention of the utility in real time. This paper discusses a
management plan for distribution of electricity. The idea of the research is to create such a balance in the load distribution to
avoid total shutdown in any region. Power is distributed in such a way that all users can at least enjoy basic household devices in
all times of the day without the use of personal energy producing (generators) and energy storing (Uninterrupted Power Supply)
devices. In this paper,systematic empirical investigation of data was performed. Moreover the disadvantages of alternative
energy devices are explored and alternates are identified

ABSTRACT-One of the key measures of the adaptability of a wander is its ability to attain satisfaction on time and on
arrangement, paying little personality to the turbulent and sketchy environment it may work inside. Cost estimation and
emulating are in this way key when making a system. Cost estimation has long been a testing errand in structures change and
despite the way that much examine has watched standard schedules, little is contemplated estimation in the quick framework
stadium. This is surprising given that the lessening of liability and change time is the primary impulse behind the ascent of the
spry technique standard. This study analyzes the substantiality of momentum estimation strategies to extra handy change
approaches by focusing on four examination tries of composed procedure utilize across over different affiliations. The study
uncovered that estimation slip was a less consistent occasion for these associations. The repeat, with which checks are required
on spry endeavors, consistently at beginning of every one cycle, intimated that the associations found estimation easier than
when widespread approaches were used. The key estimation systems used were expert data and comparability to past exercises.
Different recommendations could be drawn from the investigation: estimation models are not a crucial a piece of the procedure;
adjusted quality arrangements can show supportive for both designers and customers; and experience and past undertaking data
should be accounted for and used to backing the estimation of following exercises.

ABSTRACT—Unicast video streaming is an important real-time application with strict requirements of throughput and temporal
parameters. Geostationary satellite links play key role in IP-based services to remote region where terrestrial networks are
impractical. Satellite networks effects quality of service (QoS) of video streaming significantly due to long propagation delay and
lossy links. Analysis of QoS for video streaming is performed by designing link budgets using Satmaster Pro Mk9.0b and realtime measurement over C and Ku-band of Paksat-1R satellite. The QoS is analyzed by the measurable parameters of video
streaming i.e. service availability, latency, jitter, packet loss ratio and throughput. Moreover, the paper will present a
comparative analysis performed with various modulations, data rates forward error correction and code rates.

ABSTRACT:: Nanofluids (suspensions of nanosize metallic particles in fluid) are center of interest in heat transfer enhancement
research but inconsistency reports in mechanism and extent of heat transfer enhancements limits their practical applications.
This work is concerned with experimental analysis of convective heat transfer enhancement of gold/water nanofluid in laminar
flow under constant heat flux condition. Nanofluid of different concentrations was prepared by one step laser ablation method.
Results showed enhancement in heat transfer coefficient up to 8%, 15% and 23% with 0.00015, 0.00045 and 0.000667 volume
fraction of nanoparticles simultaneously. Heat transfer coefficient and Nusselt number also increases by increasing
concentration and Reynolds’s number and well known shah correlations failed to predict that much enhancement. Possible heat
enhancement mechanisms are also discussed such as particle migration, Brownian motion, high effective thermal conductivity
and enhanced thermal entry length region

ABSTRACT: Microgrid is a new technology in power generation and this system is used to provide power and heat to its local
area, such as cogeneration systems and renewable energy (wind turbines, photovoltaic cells, etc.). They are preferred for
medium or high power applications. Nanogrid most likely to be used in small local loads for rural area as they will be more
economic then the normal grid power system. Nano grids can operate independently or be connected to the mains and most likely
the internal voltage can be utilized as ac or dc. In this research paper a small scale microgrid system is proposed for smart
homes called "Nanogrid". Each houses have small electrical power system from them can be shared among houses. If it uses a
DC system instead of a general AC system, it can reduce energy loss of inverter because each generator doesn’t need an inverter.
Furthermore, it can continue to provide a power supply when blackout occurs in the bulk power system. A model of a nanogrid is
developed to simulate the operation of the centralized power control. Finally a Simulink model is presented for small houses
power range 90-285 KW.

ABSTRACT: In the present study, precipitated silica was synthesized from the corn cob by using organic acids. Corn cob ash
(CCA) was produced by soaking corn cobs in three different organic acids i.e., citric acid, acetic acid, oxalic acid and combined
solution of (50 % of each) citric acid and acetic acid. Organic acids were used to adjust the quality of the raw material and
helped to dealuminate the corn cob ash before the extraction of precipitated silica. CCA was mixed with alkali solution to
produce sodium silicate solution and precipitated silica was produced by the neutralization of sodium silicate solution. Corn
cobs soaked in citric acid produced the maximum amount of the sodium silicate solution and precipitated silica i.e., 39.43 % and
35.3 % by weight respectively. Sodium oxide (Na2O) content and silica (SiO2) content in the sodium silicate solution were also
determined. Extracted precipitated silica particles were characterized by Fourier transform infrared (FTIR), X-Ray diffraction
and Optical microscopy techniques.

ABSTRACT: Flow rate prediction is of prime importance for effectively managing and maintaining well
productivity. Optimum flow rate prediction can prevent water/gas coning, sand entry, surface equipment problems
and avoid formation damage due to imposing of excessive drawdown to reservoir. One of the most common wasy
to achieve these goals is by controlling flow rate using wellhead chokes. The aim of this paper is to develop a new
empirical Gilbert type correlation which is a function of flowing wellhead pressure, gas-liquid ratio and wellhead
choke size. To achieve this, data from 1300 experimental production tests under multi-phase critical flow
conditions from 120 Iranian offshore oil wells were used in a non-linear regression analysis. According to our
results, predicted oil flow rates from new correlation are in excellent agreement with the observed data. Our
results are also more accurate compared to those obtained from conventional methods. Furthermore, the
accuracy of the proposed correlation was validated by cross plotting of synthetic and field data. The new
correlation has an average relative deviation (ARD) of -0.18% and average absolute deviation (AAD) of 20.73%.
The dataset covers a wide range of choke sizes (12/64 to 92/64 inches) and PVT parameters. Therefore, it is
applicable in many Middle Eastern offshore oil wells mounted on satellite platforms where difficulties arise while
performing productivity tests.

ABSTRACT: Usability evaluation methods have gained a sbstantial attention in networks particularly in Intrusion Detection
System (IDS) as these evaluation methods are envisioned to achieve usability and define usability defects for a large number of
practical software’s. Despite a good number of available survey and methods on usability evaluation, we feel that there is a gap
in existing literature in terms of usability evaluation methods, IDS interfaces and following usability guidelines in IDS
development. This paper reviews the state of the art for improving usability of networks that illustrates the issues and challenges
in the context of design matters. Further, we propose the taxonomy of key issues in evaluation methods and usability problems.
We also define design heuristics for IDS users and interfaces that improves detection of usability defects and interface usability
compared to conventional evaluation heuristics. The similarities and differences of usability evaluation methods and usability
problems are summarized on the basis of usability factors, current evaluation methods and interfaces loopholes.

ABSTRACT: Medical images play a vital role in diagnosing different diseases. During acquisition process image acquired by
diverse imaging modalities may get worse by different types of noises. Poisson noise is one of the complicated noises, which is
very difficult from de-noising point of view. For de-noising medical images different techniques are used, wavelet transform is
one of them. In this work discrete wavelet transforms are used for Poisson noise removal using modified thresholding function on
general images as well as X-Rays, PET and SPECT images. Results of wavelet-modified filters are compared to other
conventional filters in terms of correlation, Peak signal-to-noise ratio (PSNR), mean structural similarity index measure
(MSSIM).

ABSTRACT: Evaluation of seismic safety of houses in Pakistan considering the modified seismicity of the region
after 2005 Kashmir earthquake is an important question in deciding the future seismic mitigation strategies. But
there is no right answer because a large number of uncertainties and complexities are involved in accessing the
affect of ground motions on structures. Here, we worked to answer the questions which are of core importance in
deciding the future seismic mitigation strategies. The work is discretized in five parts as follows. First; Assessment of
percentage of seismically vulnerable houses in Pakistan, second; Evaluation of modification in construction after
2005 Kashmir earthquake, third; Evaluation of expected damage if same earthquake occurs again and importance of
work out a plan to enhance seismic safety of houses against such events, fourth; Evaluation of important factors to be
considered while proposing procedures to enhance seismic safety of houses, Fifth; Comparison of different sources
to convey useful information about seismic safety of houses in general public. Owing to complexities and
uncertainties, it is difficult to answer aforementioned queries. Therefore, we used an indirect approach and contacted
100 (qualified) professionals and researchers and asked their opinions and observations. After analyzing their
responses the findings are summarized. The results of this study show that more than 75% of houses in Pakistan are
seismically vulnerable. The study also reveals that construction practices in Pakistan are either unimproved or
slightly enhanced as compared to the construction practices before 2005 Kashmir earthquake and a massive
devastation is expected if a similar earthquake strikes again in Pakistan. The results of this study are useful to decide
the future seismic mitigation strategies.

ABSTRACT: Sodium alginate is one of the important chemical uses in the reactive printing of fabric. Pakistan is also a big
consumer of sodium alginate and more than 2500 MT import in a year. Brown algae are the basic raw material for the
production of sodium alginate. China is the largest seaweed producing country and exporting its derivative. From last decay the
consumption of seaweed in food sector is rapidly increasing year by year and the shortage have to face to the alginate industry
which lift up the price of sodium alginate. From the start of February to the end of the July the pieces of naturally grown
seaweed comes on seashore. To estimate the quantity of naturally grown brown algae, a region is selected from the Manora
beach to the Hawks bay (AbdurRehman Goath) on the coastal area of Karachi. A method developed to estimate the quantity and
then scale up the data for whole season. Sargassum, Laminaria, Oyster thief and Lessonia are the types of brown algae
abundantly available on seashore of Karachi. Area under observation starts from Manora Beach to Abdulrehman Goath (Hawks
Bay). The amount of the naturally grown algae is seriously depends on the weather condition, tides and lowers, sea level and
daytime. From survey the total amount of brown algae can be collected in a season is more than 3500 MT. More than 25 percent
demand of sodium alginate can be fulfilled by utilizing natural source and also decrease the import volume. The price of the
sodium alginate can be managed by minimizing the import.

ABSTRACT: Specific properties of bentonite clay have made them a valuable material in different process industries. Easy
availability, low price and their effectiveness are the major factors which made fuller’s earth, an adsorbent in cooking oil
manufacturing industry. Textural characteristics of fuller’s earth play an important role in its performance. These characteristics
can be modified by treatment with organic acids, which is the safest method for enhancing the properties of fuller’s earth. Major
motivation of this research is to increase the adsorption capacity of fuller’s earth by modification in its properties by organic
acid treatment. Organic acid treatment assures the safety of equipment and safety of the labor as well. Four organic acids are
used which are recommended best for activation. These acids are acetic acid, phosphoric acid, citric acid and oxalic acid. Clay
is treated with all of these four acids and the acid which generates more active sites in clay is the best recommended acid for
activation.

ABSTRACT: To examine the effect of botanical extracts against mango mealy bug, Drosicha mangiferae (Green) the
experiment was carried out in mango orchard at Kamaro Sharif near Tando Allahyar, Sindh during 2013. Two methods of
spraying were carried out; five treatments with three replications were laid out. For this purpose, the plants in the orchard were
bifurcated in to two groups. Method (1) the plants were sprayed before complete settlement of all 1 st instars of mango mealy bug
on the plant panicles during their upward movement from soil to mango plants; method (2) the plants were sprayed after
complete settlement of all 1st instars on the plant panicles. Result revealed that the spraying mango plant after complete
settlement of all 1st instars of mango mealy bug was more effective than spraying the plants during settlement of 1st instars of
mango mealy bug. In both methods of spraying neem leaf extracts had significantly reduced (P<0.01) mealy bug population (~
78.10%) followed by eucalyptus (~ 71.05%), Dhatura (~ 63.30%) and Akk (~ 58.43%). It is concluded that application of neem
extract after settlement of mealy bug population onto plant panicle was the most effective method to control mealy bug
population on mango trees.

ABSTRACT: Vanadium, which is a highly toxic metal, has widespread industrial applications; hence, larger quantities of
vanadium are discharged into the aquatic environments. In this study the ability of low-cost adsorbent of eggshell was examined
and affecting factors such as: initial solution pH, adsorbent dosage, initial concentration vanadium (V) and particle size of
adsorbent (Eggshell) was investigated. The experiments were designed based on response surface methodology in central
composite design space by using Design of Expert software. Adsorption was studied in a batch system where adsorption was
found to be pH dependent with maximum removal efficiency at 2.29. The removal efficiency of vanadium (V) decreased by
increasing of initial solution pH, initial vanadium (V) concentration and particle size of adsorbent, but this efficiency increased
with increasing of eggshell dosage. The experimental data was more satisfactorily fitted with Langmuir isotherm model with
correlation coefficient of R2=0.9912. The kinetics and the factor controlling adsorption process fully accepted by pseudo-secondorder model were also discussed. The maximum adsorption capacity of vanadium (V) on to the powdered Eggshell was found to
be 3.056 mg/g.

ABSTRACT: The knowledge of groundwater resources is essential for proper planning and management of an irrigated area.
This requires recharge estimation through reliable and easy method. Thus, an attempt was made to evaluate different approaches
used for recharge estimation viz. Inflow and out flow approach, change in watertable depth approach and a computer model
(Surfer) approach. The results from three approaches indicate that ground water was recharged in November, December and
February and discharged in months of January and March of Rabi season. The difference in values of recharge based different
approaches, depending upon the nature of method was observed with similar trend throughout season. Volume of water through
canal water supplies to the fields was 22.44 against 17.71 million m 3 of the crop demand plus ETa of non cultivated area was the
considerable margin to increase the recharge in the area. To keep the water balance at required level, adverse impacts of
inflow factors ( excess irrigation, seepage losses from irrigation and drainage system) have to be minimized to reduce 26% extra
water to be recharged. Evaluation of three approaches indicated that the watertable fluctuation method is easy and reliable
method for monitoring the water balance as well as the recharge behavior in the canal command.

ABSTRACT: The study aims to evaluate the farmers’ perception and technical approach in groundwater extraction. The
information obtained and analyzed was based on questionnaire survey and some physical field measurements of discharge and
water quality of tubewells. Tubewells were used to supplement the irrigation. In the study area most of tubewells were installed
during 2000 to 2010. The intensity of tubewells in tail reaches were observed higher than middle and head reaches of secondary
canals. More than 87.5% farmers have exclusive ownership and rests 12.5% have joint ownership of the wells. The main source
of power for the well operation is electric (70%) with capacity ranged from 10 to 50 HP, whereas 27.5% well are operated by
diesel engine with an average of 20 HP. Only 2.5% tubewells operates through tractor engine. The average life of a tubewell was
reported as 10 to 35 years. The depth of tube well ranged from 25 to 105 meters with mostly 15cm suction size and 12.5 cm
delivery size. The data further depicts that 45% farmers decide the type, depth and diameter of pipe, number of strainers and
horizontal distance between strainers with their own, while 33% farmers decide these parameters with advice of mechanics. The
overall average fuel consumption of diesel operated wells ranged from 2 to 5 liter per hour. The average time spent to irrigate
one acre by a ―well only‖ was 1 to 3 hours, whereas by conjunctive use with canal water it takes 20 minutes to 1.5 hours.
Farmers manage problem of poor quality water by conjunctive use of canal and tubewell water or by using gypsum. Further
through interviews it was observed that majority of farmers didn’t know about the fresh water lenses underlain by marginal to
brackish groundwater layers.

ABSTRACT: In this paper, generalized exponential type regression estimators under simple random sampling without
replacement has been proposed for estimating the finite population mean of study variable by using two auxiliary information
in single phase sampling. The mean square error of proposed estimator is obtained up to first order approximation and bias
expressions have been derived up to second order approximation. Under the theoretical condition proposed estimators are better
than some existing estimators. An empirical study has been derived to demonstrate the efficiency of proposed estimators.

Abstract: In this paper, solution of an elliptic problem defined in a T-shaped region, using a numerical scheme is discussed. The
numerical scheme like Spectral Element Method (SEM) with domain decomposition technique is used to determine the expansion
coefficient by matching the solution and its derivatives across the boundaries of the region. The domain is divided into semiinfinite and finite rectangular elements and the solution in each element is expressed in terms of the eigen functions of the
differential operator with appropriate matching condition imposed across element boundaries. The effectiveness of the Eigen
function expansion in achieving exponential convergence has been confirmed by using Galerkin formulation of the matching
condition to determine the unknown coefficients.

ABSTRACT: Staphylococcus aureus is one of the major sources of nosocomial infections in humans. Its increasing resistance to
different antibiotics and ubiquitous presence is important cause of spreading infections. Methicillin is modified β lactam
antibiotic used to cure infections by this organism but due to presence of mecA gene in plasmid, S. aureus has developed
resistance to methicillin. Treatment of methicillin resistant S. aureus (MRSA) is difficult and can be done by vancomycins.
Extended spectrum β lactamases also pose difficulty in treatment by different drugs as they are also resistant to a number of
antibiotics. In this study, the waste water from a public sector hospital was taken and was checked for the presence of S. aureus.
A number of antibiotics including third generation cephalosporins and methicillin were used to find out bacterial sensitivity to
these drugs and one of the strains was found to be resistant to methicillin as well as cephalosporins showing that ESBLs
producing MRSA can be found in waste waters. These can cause spread of resistant bacteria and complex diseases. So it is
necessary that hospital wastes should be checked for the presence of pathogenic bacteria and proper eradication of infectious
material should be done before disposal.

ABSTRACT-The aim of the research paper is to protect the distribution transformer from dysfunctional due to the
overloading currents, high voltage spikes and over-heating of transformers oil. . Distribution transformer is a key
component for electrical energy transfer in power systems. So, appropriate protection of transformer is essential for continuity of
electric power supply. In this research paper, protection scheme is implemented using Ardunio Microcontroller that
is very high speed and cost effective device with enhanced accuracy. Microcontroller sense the current of load and
temperature of transformer continuously. As the value of current and voltages increases from pre-set values, protection scheme
operates and trips the load. Likewise, as the temperature increases to a set value, a fan would be turned on for cooling the
transformer. Complete design of protection scheme with hardware has been presented. At the end, successful results have been
shared justifying the proposed technique.
