Scientists have built the first-ever nonreciprocal circulator for sound that is able to break sound wave reciprocity. The device is a 'oneway road for sound' that transmits acoustic waves in one direction but blocks them in the other. With this device, you can listen without
being heard.
A team of researchers at The University of Texas at Austin's Cockrell School of
Engineering has built the first-ever circulator for sound. The team's experiments
successfully prove that the fundamental symmetry with which acoustic waves travel
through air between two points in space ("if you can hear, you can also be heard")
can be broken by a compact and simple device.
Using the proposed concept, we were able to create one-way communication
for sound traveling through air," said Andrea Alù, who led the project and
is an associate professor and David & Doris Lybarger Endowed Faculty
Fellow in the Cockrell School's Department of Electrical and
Computer Engineering. "Imagine being able to listen without having to
worry about being heard in return."
This successful experiment is described in "Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator," which
will be featured on the cover ofScience in the Jan. 31 issue.
An electronic circulator, typically used in communication devices and radars, is a nonreciprocal three-port device in which microwaves or
radio signals are transmitted from one port to the next in a sequential way. When one of the ports is not used, the circulator acts as an

isolator, allowing signals to flow from one port to the other, but not back. The UT Austin team realized the same functionality is true for
sound waves traveling in air, which led to the team's building of a first-of-its-kind three-port acoustic circulator.
Romain Fleury, the paper's first author and a Ph.D. student in Alù's group, said the circulator "is basically a one
-way road for sound. The
circulator can transmit acoustic waves in one direction but block them in the other, in a linear and distortion-free way."
The scientific knowledge gained from successfully building a nonreciprocal sound circulator may lead to advances in noise control, new
acoustic equipment for sonars and sound communication systems, and improved compact components for acoustic imaging and sensing.
"More broadly, our paper proves a new physical mechanism to break time-reversal symmetry and subsequently induce nonreciprocal
transmission of waves, opening important possibilities beyond applications in acoustics," Alù said. "Using the same concept,
it may
actually be possible to construct simpler, smaller and cheaper electronic circulators and other electronic components for wireless devices,
as well as to create one-way communication channels for light."
CHANICAL ENGINEERING
This research may eventually allow for an "acoustical version of one-way glass," said Preston Wilson, acoustics expert and associate
with interviews and can-
professor in the Department of Mechanical Engineering. "It also opens up avenues for very efficient sound isolation and interesting new

cally into the two receiving ports, Port 2 and Port 3, as expected. However, when the researchers turned the fans on and delivered a moderate airflow into the ring, with specific velocity tailored to the ring design, transmission symmetry was broken and the signal from Port 1
would flow entirely into Port 2, leaving Port 3 completely isolated. Conversely, when a signal was sent from Port 2, it would flow into
Port 3, leaving Port 1 isolated. Acoustic signals then flow from Port 1 to Port 2, from Port 2 to Port 3 and from Port 3 to Port 1, but not in
the opposite directions.

all the departments. Congratulations ,to the students for taking such an initiative.
2.What does TEXEPHYR mean to you?
In present day’s scenario these events gives an opportunity to the students
to exhibit their talent in addition to academics. These events will improve
the employability of our students.
3.Five years down the line, what are your expectations regarding
TEXEPHYR?
Five years down the line, the technical content of this event should have a
predominance in the programme.As this is not a fun fair but instead a technical event which gives an opportunity to the students for innovation.
4.How close is the Mechanical Department to you?
I, being one of the founders of MIT, and closely associated with the progress of Mechanical Department I feel that am very proud to be on the faculty of the department. We have an excellent infrastructure in the department ,as many as 13 well equipped laboratories.Such as tribology, robotics, non conventional energy, computational fluid dynamics and many
more.
5.Words of advice for the students.
Today’s world is very competitive in addition to excellent academics ,one

SAEINDIA COLLEGIATE BRANCH
SAE is the acronym for the Society of Automobile Engineers. SAE international is
an organization of over 84000 engineers, educators and associates from over 97
countries. Founded in 1905, SAE is the leading authority in technical information
and expertise used in designing, building, maintaining and operating land, air and
sea vehicles. The collegiate branch of SAE is in charge of organizing various seminars, guest lectures, industrial visits and workshops. It acts as a direct link between
the students and the industry. SAE has a large number of members within the department. All members benefit from these privileges and opportunities. Along with
this, the members are also entitled to access ARAI`s vast library`s for any educational or research work. Another major task of the SAE collegiate branch is the total
organization and conduction of TEXEPHYR, the ANNUAL college Techfest. This
large scale festival is completely organized by the students with only a guiding
hand from the faculty. Students not only realize and hone their sense of creativity
but also understand various elements of management, organizing, accounting and
budgeting
TEAM PIRANHA RACING
TEAM ACCELERACERS
Team Acceleracer`s is a racing team of students
who develop formula style race cars. Acceleracer`s
is a group where imagination, engineering, creativity and team work thrive together. The team participates in various formula student competitions.
The first experience of the team was Supra SAE
India 2011. Initially a team of 24 students, Team
Acceleracer`s is now a union of 50 members from
different streams of engineering, who do a continual research and development in the field of automobiles. The working style of the team is more like
that of an organization than a regular college team.
Along with focusing on engineering of the vehicle,
the team also helps students explore their management and marketing skills. The last year was a
great year for our college as Team Acccleleracers
were awarded numerous accolades including 1st
place in Engineering Design and 3rd place in Marketing Presentation. High hopes are pinned on the
team to raise the bar to new heights and come back
with more awards this year.
PHYR ‘14
Baja SAE is an inter collegiate design competition run by
the Society of Automotive Engineers (SAE). The goal in
Baja SAE racing is to design , build and race off-road vehicles that can withstand the harshest elements of rough terrain. Team Piranha has a history of participating in Baja
SAE India from the past four years. The team has seen
some tough years and some memorable ones. 2012 was one
of those memorable years when the team secured 6th position in the endurance race and 18th rank overall. Even after
being 35 minutes down in a 4 hour race and starting the
race with 3laps down, the team covered about 35 laps of
that dirt track and stood 6th. In 2013 the car was top 3 in
aesthetics and was displayed in the inaugural event. Team
Piranha racing was the only team to clear all technical inspections in one go which is no mean feat as the inspections
are precise and thorough conducted by officials from top
car companies .We were one of the very few teams who
experimented with Continuously Variable Transmission
(CVT) instead of Manual Transmission. We also cleared
the gruelling hill climb of 50 metres with a gradient of
40°.Overall Team Piranha Racing stood 16th in endurance.
We have high hopes for 2014, and thank the department for
their continued support and guidance.

Our Engineering All-Rounder:Aditya Deokule
Interviewed By: Nagma Parkar And Syed Mujtaba
Brilliant student, amazing sportsman ,versatile theatre actor, popular friend and loved by
all. Aditya Dilip Deokule was everything a student could be. A go getter from the beginning , Aditya represented Pune, Maharashtra as a baseball captain at Chandigarh. He
also represented MIT for the purshottam karandak and firodia competition each year. He
acted in several plays while studying engineering.
After passing out from MIT in 2010, Aditya joined Volkswagen as he was placed in the
final year in Production and Technical service department.
His true passion for automobile drove him into the make and modeling of the first off
road vehicle of MIT college entering in SAE BAJA. Hera are a few excerpts from our
Team Texephyr: Tell us something about yourself?
AD: I basically belong to Thane, Mumbai. I did my schooling from shiv samarth vidyalaya and then joined
new english school and junior college and opted for science stream because of my true calling for automobiles.
I used to have a lot of fun and was always involved in purshottam and even represented as the captain of the
baseball team.
TT: How was your team at MIT?
AD: My time at MIT was just awesome and today what I am is just because of the way MIT moulded me . I
remember P.B Joshi sir, being very helpful to me during the PLs he used to give us the keys of M303 my
“best classroom” to study day and night and never said a NO.He was just the best.
TT: Sir, Volkswagen it is how would you describe your journey till date ?
AD: I have also had my share of hurdles as any normal human being. As I did my schooling from a vernacular
media it was difficult at the start but I adjusted myself along the path. It was difficult for me to understand
how to study for engineering. I learnt how to handle extra curricular activities along with academics and then
came the day of placement which went on very smoothly. I was the only guy selected by Volkswagen which
was in it itself a very proud moment.
AD: Sir, In which ways engineering is superior to other fields?What Is your personal opinion ?
TT: Well, I would not like to distinguish engineering from other fields as every field has its own merits and
demerits. But how engineering can be made different is all upto us. I feel engineers should be logical and it
plays a very important role in every engineers carrier.
TT: I really miss my days in MIT, specially the hangouts
at anna, submissions, lunch breaks. MIT really has a different atmosphere , I regularly come to college every
week and recollect all my memories. It’s a different
feeling overall.
AD: How would you like to share your experience with
the upcoming juniors of MIT?
TT: My personal advice to all the present students is,
keep on enhancing your knowledge , try to learn something everyday. Don’t wait for opportunities to come to
you rather make one. Take initiatives of doing something
new. Gain experience as much as possible. Final year
projects play an important role in adding your experience. Apart from technical soft skills are also important.
AD:In one word , what is MIT to you?
TT: Unforgettable!

clamoring of suspension and
thumping of engine...that’s
what drives us!”

Production Machinery Automation Market: Outlook for 2014
Increasing demand for flexible machinery, machine safety and an increasing number of new original
equipment manufacturers (OEMs) in emerging economies are driving stable growth to the production machinery automation market. The production machinery automation market is expected to see continual growth
in 2014 and beyond, according to the "Production Machinery Automation Global Market Research Study"
from ARC Advisory Group.
Europe's large machinery market consists of high-end, customized machinery. As a global leader,
European machinery has demanding technical requirements, making it crucial for supplier to provide innovative, reliable solutions in order to remain competitive. China is challenging European machine builders as its
OEM sector continues to grow. Increasing wages are forcing manufacturers to invest in automation.
Global quality standards and integrated safety solutions also require more support from automation
suppliers. "Automation suppliers that offer complete solutions are more successful in the global OEM market," said Stefan Miksch, principal author of the ARC report. "Portfolio synergies can leverage automation
sales as suppliers enter the bidding phase earlier, offer the right products for the right applications, add value
to OEMs, and set up sales channels in emerging markets early."
Integration is also a key factor in production machinery, as it shortens start up time an offers competitive benefits. Integrated safety is important to the market currently, but in the future, energy management and
cyber security will soon be more heavily integrated into machines and automation
In India, industrial production measures the output of businesses integrated in industrial sector of the
economy such as manufacturing, mining, and utilities. Industrial Production in India decreased 0.60 percent
in December of 2013 over the same month in the previous year.
Industrial Production in India is reported by the
Ministry of Statistics and Programme Implementation (MOSPI). Industrial Production in India
averaged 6.81 Percent from 1994 until 2013,
reaching an all time high of 20 Percent in November of 2006 and a record low of -7.20 Percent in
February of 2009.
