Last two decades have been very significant as far

as the impact of technology on society is

concerned. Ability to send information of any

type, anywhere, and anytime has altered the way

societies live and transact their businesses, be it

education, production of goods, selling of goods,

entertainment, information transaction between

individuals, individual to masses, health care,

governance etc. Every aspect of social order is

getting affected, this is only the beginning of

changes in a technology driven society. What

technology holds for the society is any one’s

guess? Some of the scientists and thinkers have

tried to predict what science and technology holds

for us, say by 2030. Michio Kaku (Great Physicist

of our time) expresses in his book ‘Physics of the

Future’ and video lecture ‘The world in 2030’

(You Tube), a glimpse of technology driven

society and our role in it. This is just decade and

half away.

To stay relevant as an engineer, or as a

technologist, or as a scientist in tomorrow’s

society is not going to be easy for any student.

Therefore, effective utilisation of four years for

any student in the institute has become very

crucial. One can choose to improve upon their

class room participation by doing following:

Asking questions.

Studying together.

Not blaming your Professor.

Being prepared to work hard but know your

limits.

Getting involved with the work.

Taking notes. (Do not use electronic devices)

Taking pride in your work.

Not underestimating yourself.

When in doubt, draw the blocks

connect them logically and see if

system works.

Get enough physical exercise,

health is real wealth.

Above will help you in grooming

yourself with the set of skills that will

be imperative for engineers of

tomorrow.

I welcome all undergraduate and

postgraduate students who have

joined the department during currant

academic year. I hope they value their

time and utilise departmental facilities

optimally. Department has also

submitted application for

accreditation of its undergraduate

program to NBA. NBA team is likely to

visit the department during the first

half of the next semester. The focus of

assessment will be ‘outcome based

education (OBE)’. A buzz world for

tomorrow’s engineering education in

India. Our country has also become a

full member of Washington Accord.

Let’s have good time during the

semester. Good luck and Bye.

From HOD’s Desk

The EC department follows a modular approach and comprises of four modules as seen below:

CRUX OF EC DEPARTMENT

Quanta the official technical society of our college established in 2000 with a motto to develop theoretical

cum practical knowledge that enhances a persons’ command over different domains of electronics including

embedded systems, robotics ,VLSI ,simulation. It seeks to ignite the spark of electronics in every student who

belongs to this field and gives the exposure to move on. More than 75 workshops have been conducted since

then proving it to be a constant facilitator in scientific and technical education of students. Adding to the array

was the workshop on advanced embedded system conducted last month which lasted for 3 days. More than

70 students participated making a total of 18 LFRs.

QUANTA has a young and dynamic team with a passion for electronics, trying to prove its existence above all

other similar societies .Its members have made the college proud by winning accolades in competitions such

as TIIC ,Intel Innovation Challenge and various techfest .Recently it has recruited 20 more very passionate

enthusiast from all branches of 1st year B.tech. And this quest of excellence continues...

Quanta –Exploring Imaginations…..

Reminiscing Memories with Prof.KHNV Lakshmi…..

The Department bid

farewell to one of its most

promising professors on

12th May 2014.Here are

some excerpts from the

interview by Siddhartha

Agarwal, wherein she

shares some of her

profound memories.

Interviewer: How does it feel when you look back upon the time that you spent in JSS?

KHNV Lakshmi: It feels great that I had served JSS for such a long time. I feel very

sad that I had to leave JSS.

Interviewer: How did you choose to be a teacher?

KHNV Lakshmi: I suppose it’s in my blood. I did not opt for teaching as my first job as I

believed that one needs to have practical exposure to be a good teacher. After working

in the industry for about 9yrs, I had the confidence that I would do justice to the

profession and hence started teaching.

Interviewer: If not JSS, where would you have been?

KHNV Laksmi: If not JSS, may be I would have not been a teacher, but an R & D

engineer in any of the core electronics company or in corporate training. Since, the

environment at JSS was too good which no other college in NCR had provided I

chose to enter this profession.

Interviewer: What do you miss the most about JSS?

KHNV Lakshmi: Teaching has always been a passion for me. So, I miss my students

the most. Of course the wonderful ECE department, my colleagues and HOD who was

always willing to guide the students and the faculty.

Interviewer: A few notable words to students….

KHNV Lakshmi:Education means overall personality development with human values

and ethics not only degrees.

So one should study to gain knowledge, not for marks or degrees. Once you gain

knowledge you will earn degrees automatically.

The key to success is sincerity and discipline. Its al about competing with

yourself so do not compete with others compete with yourself and never get

disheartened by your failures.

Do not let your success go above your head. The more you learn the more

humble you are and cultivate the habit of lifelong learning. The best teacher is

the nature and your experience.

I believe a good student makes a good teacher.

Interviewed by-Siddhartha Agarwal

Waking up is hard to do. But a new kind of LED light bulbs could help to

ease those peaky transitions between night and day by coaxing

cooperation out of your melatonin levels. Melatonin is the hormone in

charge of making you feel sleepy , and your levels go up and down on a

24 hours cycle each day. When you wake up bright eyed and bushy

tailed, your melatonin levels tend to be low. But as the day gets longer

and the sun starts to go down, the hormone production will ramp up

again.

LED TO THE RESCUE:

The problem is if you are a graduate student, or you work the night

shift, or your bed happens to be on the International Space Station

(where the sun rises every 90 minutes),you don’t have the luxury of

going to the bed when the sun goes down. Luckily, a company called

Lighting Science has an app for that.

Their smart bulb, called Rhythm Downlight ,works like this, as per the

popular science:You program your desired sleep schedule in the app,

which syncs up with the specially designed digital LED light bulb. When

it’s time to ramp up for your next shift ,the bulb will emit more light in

the blue spectrum ,which shuts down melatonin production ,helping

you to feel awake .But when it’s time to crash ,the blue light is no more,

allowing you to drift off. At this point the company produces a pro-wake

bulb and a pro – sleep version. The rhythm Downlight version ,which

aims to alternate between the two, is due for release this summers.

In this era of instant coffee, where the word is moving from

snailmail to hotmail, the government has directed its top

guns towards, the digitalising the nation. The Modi

Government has taken up the half baked plans and worked

upon them to expunge the economic woes of the nation.

The economy which was crawling at its slowest pace is

expected to experience a meteoric rise in development with

digitalisation of the country. The recent biggest step

observed in this direction is the partnership of Modi

Government with Google India to increase the access to

internet by working upon development of Non-English

Internet user base. This shall be a step towards increasing

employability as well. The increase in smart gadgets such as

smart phones, smart watches etc. have sparked a wave of

innovation that has brought new services to millions and

efficiencies to business of every type. To accelerate Digital

India Programme, introduction of E-visa Technology ,

Modernisation of railway using technology, building of

virtual schools are planned to be implemented by

December 2014.A revamp of Indian Railways will introduce

new features such as Wi-Fi services on trains, next

generation e-ticketing systems, GIS mapping and

digitalisation of records. The prime step introduced in the

budget to increase FOI in the telecom sectors has proved

boon in the prosper of digitalisation program. Due to import

duty levied on certain telecom service,it presents an

opportunity to foreign companies to invest in Indian start-

ups .The pace of movement being undertaken by

government in still an optimistic mind-set among analysts

regarding the economic growth. A leverage in IT and

telecom sector growth is expected in coming years.

According to the words of Rajan Anandan, MD of the

Internet Giant’s Indian division, “India is where China had

been in 2006 or 2007”.This can imbibe a positive feeling

that the nation is on the headway and shall complete its

journey of progress to be among the world beaters soon.

No! It’s not a snap from some

science fiction movie. It’s REX, world’s first bionic man. While

scientists have built many artificial organs individually, they have

never before been put together to create an entire human body. Rex

or as he has recently been renamed Frank (after Frankenstein), the

world's first fully functional bionic man has just changed that. Rex

who was first unveiled at London's Science Museum in February of

this year is now on display at the National Air And Space Museum in

Washington D.C., the human clone was assembled in three short

months using state-of-the-art organs that were donated by 17

manufacturers - A good thing given that the total cost came to about

$1 million USD!

The dapper bionic man whose face is modeled after University of

Zurich psychologist Bertoit Meyer who led the project, is six and half

feet tall, weighs 170lbs and can sit, stand and walk with the help of

an exoskeleton.

While the exterior is certainly interesting, it is as they say what's on

the inside, that matters - And in Rex's case there is plenty –

Starting from most technologically advanced robotic limbs to a

THE BIONIC MAN!

Starting from most technologically advanced robotic

limbs to a functioning heart that pumps oxygen and

artificial blood around his body. He also has a lung,

kidney, spleen and even a pancreas. A retinal implant

allows the bionic man to sense objects found him, while

around him, while a cochlear insert enables him to hear.

All in all, Rex aka Frank has about 60-70 percent functionality of a

normal human. He is still missing some key parts like a digestive

system, liver, skin and most importantly, a brain!

According to Richard Walker, the lead roboticist at London-based

Shadow Robot Company responsible for creating the bionic man, Rex

was assembled to showcase the advances in aesthetic prostheses for

people that have lost their limbs or part of their face and maybe even

an organ. Having said that, while the organs worked well on Rex some

like the kidney, are still in early trial phase and not ready to be used on

humans yet.

AGE OF 3-D INTEGRATION

Xilinx All Programmable 3D ICs utilize stacked silicon interconnect (SSI) technology to break

through the limitations of Moore’s law and deliver the capabilities to satisfy the most demanding

design requirements. Xilinx homogeneous and heterogeneous 3D ICs deliver the highest logic

parts are as tiny as a fraction of the diameter of a human hair.

These inventions are essential to build micro-robots that can

be used as surgical tools, sensing machines to explore disaster

zones or manufacturing tools to assemble micro-machines.

The micro-windmills can be made in an array using the batch

processes. The fabrication cost of making one device is the

same as making hundreds or thousands on a single wafer,

which enables for mass production of very inexpensive

systems. "Imagine that they can be cheaply made on the

surfaces of portable electronics," Chiao said, "so you can

place them on a sleeve for your smart phone. When the

phone is out of battery power, all you need to do is to put on

the sleeve, wave the phone in the air for a few minutes and

you can use the phone again."Chiao said because of the small

sizes, flat panels with thousand of windmills could be made

and mounted on the walls of houses or building to harvest

energy for lighting, security or environmental sensing and

wireless communication.

MICRO-WINDMILLS TO RECHARGE PHONES

A UT Arlington research associate and electrical engineering

professor have designed a micro-windmill that generates

wind energy and may become an innovative solution to cell

phone batteries constantly in need of recharging and home

energy generation where large windmills are not preferred.

Smitha Rao and J.-C. Chiao designed and built the device that

is about 1.8 mm at its widest point. A single grain of rice could

hold about 10 of these tiny windmills. Hundreds of the

windmills could be embedded in a sleeve for a cell phone.

Wind, created by waving the cell phone in air or holding it up

to an open window on a windy day, would generate the

electricity that could be collected by the cell phone's battery.

Rao's designs blend origami concepts into conventional wafer-

scale semiconductor device layouts so complex 3-D moveable

mechanical structures can be self-assembled from two-

dimensional metal

pieces utilizing planar multilayer electroplating techniques.

electro mechanical system research and started a relationship

with UT Arlington. An agreement has been established for UT

Arlington to hold the intellectual properties while WinMEMS

explores the commercialization opportunities. UT Arlington

has applied for a provisional patent. Currently , WinMEMS has

been showcasing UT Arlington's works on its website and in

public presentations, which include the micro-windmills,

gears, inductors, pop-up switches and grippers. All of those

parts are as tiny as a fraction of the diameter of a human hair.

BENEFITS Footprint:

More functionality fits into a small space. This extends Moore's

law and enables a new generation of tiny but powerful devices.

Cost:

Partitioning a large chip into multiple smaller dies with 3D

stacking can improve the yield and reduce the fabrication cost if

individual dies are tested separately.

Heterogeneous integration:

Circuit layers can be built with different processes, or even on

different types of wafers. This means that components can be

optimized to a much greater degree than if they were built

together on a single wafer. Moreover, components with

incompatible manufacturing could be combined in a single 3D IC.

Shorter interconnect:

The average wire length is reduced. Given that 3D wires have

much higher capacitance than conventional in-die wires, circuit

delay may or may not improve.

Power:

Keeping a signal on-chip can reduce its power consumption by

10–100 times. Reducing the power budget leads to less heat

generation, extended battery life, and lower cost of operation.

CHALLENGES

Yield:

Each extra manufacturing step adds a risk for defects. In order for 3D

ICs to be commercially viable, defects could be repaired or tolerated,

or defect density can be improved.

Heat:

Heat building up within the stack must be dissipated. This is an

inevitable issue as electrical proximity correlates with thermal

proximity. Specific thermal hotspots must be more carefully managed.

Testing:

To achieve high overall yield and reduce costs, separate testing of

independent dies is essential. However, tight integration between

adjacent active layers in 3D ICs entails a significant amount of

interconnect between different sections of the same circuit module

that were partitioned to different dies.

Lack of standards:

There are few standards for TSV-based 3D-IC design manufacturing,

and packaging. Heterogeneous integration supply chain

heterogeneously integrated systems, the delay of one part from one of

the different parts suppliers delays the delivery of the whole product,

and so delays the revenue for each of the 3D-IC part suppliers.

E-TEXTILES E-textile referred to as intelligent clothing or smart clothing

that allow for the incorporation of built-in technological

elements in everyday textiles and clothes. While not part of

the mainstream form of fashion, its popularity is increasing

and more research is being devoted to it. Smart fabrics are

ones which can change/react automatically to their

surroundings. Smart fabrics (- or intelligent textiles) are

being developed to be able to sense what is happening to

the wearer or its immediate surroundings.

In particular, integrating sensors and computational devices

into fabrics will enable the fabrics to provide a much richer

set of capabilities than is currently possible. These electronic

textiles (e-textiles) will allow us to build smart garments, as

well as home and office furnishings that look and feel like

their everyday counterparts while being able to sense our

presence, monitor our health, and dynamically adapt to our

individual needs.

The field of e-textiles can be divided into two main

categories:

1) the first category involves mounting classical electronic

devices such as conducting wires, ICs, LEDs and conventional

batteries into garments.

2) The second category involves creating electronic function

directly on the textile fibers. These functions can either be

passive such as pure wires, conducting textile fibers, or more

advanced functions such as transistors, diodes and solar

cells.

2) The second category involves creating electronic function

passive such as pure wires, conducting textile fibres, or more

advanced functions such as transistors, diodes and solar

cells. The field of embedding advanced electronic

components onto textile fibres is sometimes referred to as

fibertronics.

Uses of conductive fibers and textiles include static

dissipation, EMI shielding, signal and power transfer in low

resistance versions, and as a heating element in higher

resistance versions. Their benefits over solid or stranded

metal wires come from conductive fibers’ flexibility and

ability to use in existing textile machinery.

There is a wide range of applications for E-textiles like

Technical outdoor apparel (Trekking, mountaineering,

special task force etc.), Fire Brigade, metal casting

industry,Commercial food-processing protection, Industrial

safety and protection.

The growth is attributed to the concerted industry’s effort

on developing self-powered smart textiles and also to the

improvement in energy harvesting mechanism in the coming

years. Smart textiles is poised to witness staggering growth

in the coming years. Pujya pandey,3rd year

Lie detector is to ascertain whether the person is telling truth or

false. It is also referred as deception detector which uses

questioning techniques along with technology that record

physiological functions. It is commonly used by law enforcement.

Components required to make this project are as follows:

Circuit board, Resistors (10k, 47k, 470,1M) ohms, 47K ohms Variable

resistor, three 2N3904 transistors, 100nf capacitor, slide switch, 9V

battery, LED (one red, one green), soldering tools, drill, basic tools,

Velcro, aluminium foil. The circuit diagram of the Lie Detector is

shown in fig. It consists of three transistors (TR1 to TR3), a capacitor

(C1), two lights or LEDs L1 & L2), five resistors (R1 to R5), and a

variable resistor (VR1). This circuit is based on the fact that a

person's skin resistance changes when they sweat (sweating

because they're lying). Dry skin has a resistance of about 1 million

ohms, whereas the resistance of moist skin is reduced by a factor of

ten or more. Resistors R1 and R2 form a voltage divider. They have

resistances of 1M ohms, as their values are equal, the voltage at the

upper probe wire is half of the battery voltage (about 4.5 volts).A

person holding the probe wires will change the voltage at the upper

probe wire depending on their skin resistance. The skin resistance is

in parallel with R2 and, because it is likely to be similar to or smaller

than R2, the voltage at the probe wire will fall as skin resistance

falls. Capacitor C1 functions as a smoothing capacitor and removes

the 50Hz induced mains hum that is found on a person's body.

TR1 and R3 form a buffer circuit (called an emitter-follower). The

voltage at the emitter of TR1 follows the voltage at the probe wire

and is now able to drive transistor TR2. Transistors TR1 and TR2 act

as a voltage comparator. If the voltage at the base of TR2 is higher

than at the base of TR3 then the green LED (L1) will come on. If the

reverse is true then the red LED (L2) will light. To test the Lie

Detector hold the probe wires. Adjust VR1 until the green LED is just

on and the red LED is just off. This is the point at which the voltage

at the base of TR2 is just greater than at the base of TR3. Now use

moist fingers to hold the probes. This lowers the skin resistance and

causes the voltage at the base of TR2 to fall. The voltage at the base

of TR3 is now greater and the red LED comes on.

Steps:

1) Make a finger pads by sticking an aluminium foil to the

Velcro and don't forget to stick a wire between the Velcro

and thin foil.

TRY IT YOURSELF!

2) Soldering the circuit

3) Drill a tin box.

4) Place the circuit in it.

5) Done.

Challenge (TIIC)? Was it totally unexpected or well planned?

Gaurav: As I said, everything is happening unintentionally. The group

with which I worked, I met them only a few months before the

abstract submission date. It was only a little sprout of an idea that

had been flourishing in our minds "ki yaar kuch bada karna h (that

we have to make it big)", but never did we expect that it would

happen. Seeing our past success rate, anybody could’ve said that

odds were stacked against us. When we submitted the final video in

February, we were totally sure that we would fail, moreover we also

started disassembling our project and started working on another

one. But surprises were waiting for us, never could’ve we guessed

what the future had in store for us. But surprises were waiting for us,

never could’ve we guessed what the future had in store for us.

Interviewer: A life event that was inadvertent, but you still lure for

that moment?

Gaurav: Honestly, everything is happening inadvertently with me

since I took admission in JSS. I remember my last year's trip to

Rishikesh, I mean who bunks their sessionals just to experience the

thrill of an adventure. I really wish I could witness it once again.

Interviewer: What has been your most memorable moment till

date?

Gaurav: Well, there have been many. But the best thing that

happened in these years was my friends. They always supported me

unconditionally through my thicks and thins. You know, it’s very

difficult to find a person with the same mental disorders as yours,

but I’m lucky to have six, Shubham, Rishu, Shikhar, Sujit, Eshant and

of course Ajeetesh. You guys are the best part of my college life.

Interviewer: If not engineering what would be the other field that

you would have gone for?

Gaurav: I never had the confusion as to which field I should opt

for. But apart from that, I love dancing. I do it whenever I’m free. I

would have tried pursuing it if not engineering.

Interviewer: What has been that one lesson you’ll never forget,

that your college life has taught you?

Gaurav: Frankly speaking, apart from the college itself, college life

has taught me a lot, and I’m still learning. How to make friends,

which ones will actually help you, and which ones are just there

for your glory. How to set your priorities. Before entering this

college, I was the average boring guy, but soon after there has

been an exponential change in my personality and attitude .I

believe every day is a new day and I find myself challenging my

own beliefs and overcoming them. Being a budding engineer gives

me a lot of responsibilities towards everything and especially

everyone, and I try my best to carry them out.

Interviewer: How has life changed post TIIC?

Gaurav: I don’t know why everyone asks me this question. It isn't

a very great achievement. Things were the same before TI as they

are now and they will remain the same ever. But yes, now people

around me have started showing some faith in me. The

department itself is one such example. Now at least people know

that I’m not simply fantasising. If I say I can design this, it simply

means "I can".

Interviewer: What is the ultimate goal of your life?

Gaurav: I want to become a scientist and contribute, in the

technical field.

Interviewer: What would be your advice for juniors?

Gaurav: Never get disappointed in your life and never regret the

decisions that you’ve made. Many of you had once dreamt of

getting admission in IITs but unfortunately that didn’t happen. But

that wasn’t the end of your engineering dream. Motivate yourself

and challenge yourself every day, compete with yourself. And no

matter what others think of you, just try hard to achieve your

dream. Don't give yourself a chance to regret that once you had

time but you did nothing. At least you should be satisfied that you

did something.

CHECK YOUR QUANTABILITY

Friends as you know, the first step towards getting a job

almost anywhere is to clear an aptitude examination. The

major section of these aptitude examinations is

quantitative ability. It becomes imperative that we clear

this part of the examination, and only then we are allowed
