HOD SPEAK

.Luck is not chance—

Its toil—

Fortune’s expensive smile

Is earned..

My dear friends, the road to success is not smooth. The ignited mind of the youth is the most

powerful resource on the earth, above the earth and under the earth. The youth power, if

properly directed and controlled, could bring about transformational changes in humanity for its

progress, meeting its challenges and bring peace and prosperity.

INDUSTRIAL VISIT TO GMRT:

The National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fun-damental Research (TIFR) has an active research program in many areas of Astronomy and Astrophysics, which includes studies of the Sun, interplanetary scintillations, pulsars, the Interstellar medium, active galaxies and cosmology. The preview started with Dr. Anand Tripathi having discussion with Mr. J.K.Solanki of GMRT Pune, regarding permission to visit GMRT. February 28 being International Science day it was free to all. Maharashtra State Transport bus was booked for commuting between Mumbai and Narayanangaon Pune. The trip was taken on the 28th of February 2013. The attendees were 73

SE ETRX, students and Dr. Anand Tripathi, Prof. Geetha Narayanan, Prof. Divya

Nair and Prof. Mayur Kudalkar.

NCRA currently operates the Giant Metrewave Radio Telescope (GMRT), which is located approximately 80 km north of Pune, India and is the largest Radio Telescope operating at low radio frequencies. It is an open access facility and is used by astronomers across the world. Here 30 fully steerable dish type antennas are indigenously designed & constructed and arranged in a Y shaped array over a 25 km region. The importance and application of the project was explained to the students. Antenna C3 is a giant Radio Antenna with the following specifications. The number and configuration of the dishes was opti-mized to meet the principal astrophysical objectives which require sensitivity at high angular resolution as well as ability to image radio emission from diffuse extended regions. Fourteen of the thirty dishes are located more or less random-ly in a compact Central Array in a region of about 1 sq km. The remaining sixteen dishes are spread out along the 3 arms of an approximately `Y'-Shaped configu-ration over a much larger region, with the longest interferometric baseline of about 25 km. The multiplication or correlation of radio signals from all the 435 possible pairs of antennas or interferometers over several hours will thus enable radio images of celestial objects to be synthesized with a resolution equivalent to that obtainable with a single gigantic dish 25 kilometre in diameter! There were stalls exhibiting and explaining each section of the antenna in detail. The infor-mation was presented in a well-organized manner relating each section to the other and the system as a whole.Also there were exhibitions illustrating a s t r o -nomical themes and concepts, exciting results obtained with the GMRT, various subsystems of GMRT and illustrative models. There were also programmes to interact with well-known scientists and engineers and film shows on astronomi-

cal topics of current interest.

Our students attended a talk by Mr. Pramod Kale, Director, VLSI center, Electronic science Department, University of Pune, on the topic – ‘Science in Bicycles’. This followed by a movie screening showcasing ‘Albert

Einstein’s concept of space and time’

TECHNOLOGY UPDATES— Wireless Charging Soon Available for Devices Smaller Than Mobile

Phones Wireless charging will soon be available for more and more mobile

phones. VTT Technical Research Centre of Finland is working with the indus-

try's leading technological companies and standardisation bodies to expand the

scope of application of wireless charging technology to other, smaller portable

devices, such as mobile phone accessories, wrist devices, wireless mice and

sensors. This can be done by combining wireless power transmission with NFC

connectivity technology, which enables cost-effective and compact design.

Consumer need to recharge the batteries of various kinds of porta-

ble devices, whenever and wherever, continues to grow. Over the next five

years, wireless charging will be available for more and more mobile devices.

The first mobile phones with wireless charging capability are already on the

market. Examples include recent smartphone releases by leading mobile phone

manufacturers, many of which have wireless charging either built in or available

through a special cover accessory charging case. The increase of features in

mobile devices has caused cost pressures, increased power consumption, and

created new challenges for keeping devices sufficiently compact. Combining

wirLess charging with NFC (Near Field Communication) technology makes it

possible to design increasingly compact and cost-effective wireless charging

circuits, which is essential especially for small devices. In the near future, NFC

devices will be able to receive electrical power wirelessly, as well as acting as char-

ging platforms capable of transmitting wireless electrical power.

HOW STUFF WORKS– MAGLEV TRAINS

A few countries are using powerful electromagnets to develop high-

speed trains, called maglev trains. Maglev is short for magnetic levita-

tion, which means that these trains will float over a guideway using the

basic principles of magnets to replace the old steel wheel and track

trains.

Electromagnetic Suspension (EMS)­If you've ever played with mag-

nets, you know that opposite poles attract and like poles repel each

other. This is the basic principle behind electromagnetic propulsion.

Electromagnets are similar to other magnets in that they attract metal

objects, but the magnetic pull is temporary. .

The Maglev Track-The magnetized coil running along the track, called a

guideway, repels the large magnets on the train's undercarriage, allow-

ing the train to levitate between 0.39 and 3.93 inches (1 to 10 cm) above

the guideway. Once the train is levitated, power is supplied to the coils

within the guideway walls to create a unique system of magnetic fields

that pull and push the train along the guideway. The electric current

supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils.

INDUSTRIAL VISIT TO L&T,

POWAI

The industrial visit to L&T, Powai was conducted on 13th February

2013. The attendees were 11 TE ETRX,EXTC students and Prof.

Geetha Narayanan. The motive behind the trip was to To start the

industrial internship/BE project with L&T powai so that we can improve

the quality of BE projects by including the industry requirements .We

had Mr. Rahul Rane from L&T Auomation and control and Mr. K

Sreekumar Vice President Defence Electronics Department L&T HED

as advisory committee members of our institute. During the visit they

had suggested that we can make our students do BE projects /

Internships with L&T. The channel for the internships and projects from

L&T is through L&T institute at Powai. So after talking with Prof. Dama-

he Principal L&T institute we had arranged a meeting of our TE stu-

dents of ETRX,EXTC with Prof. Damahe, Prof.Sangita Vazirani .In the

meeting Prof. Damahe briefed them about the various projects and

departments in L&T and also has taken the CVs and mark sheets of

our students. Now they will be called for internships after shortlisting them according to availability of projects By having an

interaction with organizations like L&T will widen the knowledge spectrum of the students and it will also make them better

employable Engineers..

GUEST LECTURE– CONVERSION OF B.E PROJECTS

INTO MONETARY PRODUCTS

Mr. Aslam Moolji spoke to our final year students on ‘Ways to convert

projects to monetary products’ on 8th February 2013. Mr. Aslam Moolji is the founder of Arshad Electronics Pvt Ltd. (AEPL). He is a visionary

and a thinker ahead of his times. He introduced the first indigenous

Corona Treater in India. Also introduced the first Solid State Induction

Cap Sealing Machine. With over 8000 installations of Corona Treaters

and over 5000 installations of Induction Cap Sealers in India and

around the world, his company assures precision and quality in prod-

ucts .In the year 2000, AEPL introduced ozone generators for the

water industry and went on to become the leading manufacturers of

ozone generators under the brand name Arrshad Ozonics.The stu-

dents could understand the importance of being at different places in

the same time. They were taught to look out on the application part of

their final year project more than other aspects. The students were invited at his Vasai Works to gain exposure to the real world

of manufacturing.

STUDENT SPEAK-

Eagle eyes

He was panting profusely, sweat dripping from his forehead, calf muscles pumping like an electric motor as he ran

with all his might across the field with the ball dribbling at his feet. He was in total control of the ball but still unsure of what he

exactly wanted to do with it.He started weighing his options in his head, he had to pick between personal glory and the team. He

could sense the defenders gaining on him, he had to make a choice and that to fast. He rose his head to have a gaze at the pi tch

while he continued running on the flank. All his players seemed to be marked and he couldn't decide his next move. He saw

ahead and planned that all he had was 20 yards before him before he had to make the final pass. He could either attack or pass

the ball back and help his team keep possession (but that's not wingers are made up of).So he had a glance across the pitch

searching for on opening, any sort of gap he could put the ball past the opposition players, his head throbbing with the adrenalin

rush.10 more yards to go and that's when he pulled the brakes and slowed down the pace in order to make the perfect

pass.There seemed to be no opening and all he could see was the defenders. The time had come,he had to make the pass.His

pupil's widened as he swept the ball across the field, there was a gleam of hope in his eyes as he saw the ball sail past the de-

fenders and land right at the foot of his player who put the ball past the goalkeeper with the sweetest of finishes.This ball seemed

impossible a few moments ago,his mind may have been blank before making the pass,the pass may have been made uncon-

sciously,he did not see any opening a while back but yet he made the perfect pass.T his is because of the vision he had in his

mind,the picture perfect map of the pitch and all its players as they were positioned and with this vision and a mixture of calculat-

ed risk and anticipation he managed to put on a poker face and outsmart the defenders and provide an assist.And to do all this he

had a maximum of 15 seconds and still he proved to be successful. Its all a matter of skill, talent, game sense, vision ,anticipation

and most importantly eagle eyes......Who said that only great men, philosophers, soothsayers and pioneers have great

vision. I believe that the greatest vision is that of a WINGER
