From the HOD’s Desk

The EE society provides a forum where students

can show their talent in co and extra-curricular

activities. The goal of the EE society is to foster

interaction among students and faculty and help

shaping young minds into a well groomed

personality for their all-round development. It is

very sad to see that the enthusiasm in

interactions and activities of the society is

gradually declining. Although, reasons are

attributed to very busy schedule for both

students and faculty I feel it is something deeper.

Time that was previously spent interacting socially is increasingly been displaced by the

virtual variety. Students now spend more time alone in front of computer screens than

doing anything else.

Recently an article “Well Connected?: The Biological Implications of ‘Social Networking’ in

Biologist (Volume 56 Number 1, February 2009) has reported a dramatic decline since 1987

in hours per day of face-to-face social interaction as the use of electronic media has

dramatically increased. I was astonished with their findings that “global alterations in

human gene transcription, immune system cytokines and Natural Killer (NK) cells, narrowing

of major arteries, incidence of stroke, early death, high blood pressure, dementia,

Alzheimer’s, and even the common cold, can all be linked to changes in our social patterns”.

This clearly is a warning signal and all of us (faculty and students) must make sincere effort

to ensure that we talk and interact with each other at least a couple of hours every day. It

will not only create healthier atmosphere in the institute but will be good for our health

also. I think EE society should take a pro-active role and help encourage social interactions

among students and faculty by organizing games, talks on interesting topics, picnics etc.

I would like to congratulate the faculty and students involved with the society for the

commendable job they have done this year and would expect that they would do even

better next year. As the Head of the Department of Electrical Engineering it gives me

immense pleasure to see that POWER magazine, a culmination of EE Society’s year long

effort is finally going to be in your hands. My best wishes to all the outgoing students. I am

sure they will make us proud wherever they go. I will also like to tell them that this is your

home and you are always welcome here.

“A person starts to live when he can live outside himself”

Albert Einstein

It’s indeed a happy occasion that the EE society magazine is going to be published this year

again.

At the beginning of the year we aimed at two goals. One was to enhance activities of the EE

society and the second was to shorten the gap between the different sections of the

students in the department.

May be every thing could not be achieved up to the satisfaction level, but the progress is

noteworthy and all credit goes to the EE society students team.

I must say that the co-ordination among the team members was remarkable and hope that

it will be continued in the future.

Wishing every one best of luck

From the Desk of the President

I have been contemplating about writing this article as it would be the final brick in my tenure as the president of EE society. All accolades to Bhaskar, for pursuing such a gigantic task of bringing out the magazine after a gap of one year and Shihir Modi who brought us the sponsors; without their support “Power ’10” would only be a dream.

As the President of the society I have tried to build bridges between its members to the best of my abilities. At times I might have fallen back, I do apologize for that. I thank all of my team members: Khurana, Bhaskar, Souvik Da, Ekansh , Avneet, Shishir and Megha for believing in me and sharing my dreams. Above all, I would like to thank Prof. N.K Kishore, Prof. Karabi Biswas and all the professors of our department for showing faith in us and guiding us.

I take immense pleasure in walking you all through the society’s activities throughout the year. The society’s calendar started with our customary “fresher’s welcome” attended by all the first years and professors. It gave the freshers a stage to learn about the giant EE kinship of which they have become a part. Next in the line was “An interactive session on Stress Management” by Dr. T.K. Maiti, an initiative taken by Prof NK Kishore, which was appreciated by the students’ community for its learning experience. This was followed by the farewell to Professor TK Basu on behalf of the students, where Prof.Basu and students shared their interesting experiences on a common forum. Spring semester started with first of its kind Industrial trip to Kolaghat power plant accompanied by Prof Anirban Mukherjee. The trip gave students a chance to learn more about the working of a power plant, where they got a chance to see the application of the fundamentals that they have learned in theory.

The Society feels proud to have helped the batch of 2010 establish “Rohit Kumar Memorial Scholarship” in the name of our beloved friend Rohit Kumar whom we lost last year. This scholarship will help students to cherish Rohit in the best of spirits, while appreciating budding young talents. On a personal note I would like to see this scholarship grow in the coming years and touch many more lives. We thank everyone who has bought the departmental T-shirt and supported the noble cause from the depths of our hearts.

The Year ended with a hearty farewell with well wishes and blessing form professors, a splendid performance by instrumentation passing outs, a sumptuous dinner and a brain storming session for deciding the winners of “Electrical Departmental Popular awards”.

My humble gratitude to the respected professors; like all passing outs it’s time for me to say, adieu. I wish all the very best to passing outs as well as to my juniors for success in their personal and professional lives. God Bless you all.

G.Sec Speaks

It’s been close to eight months since Vishal (last year’s G.Sec) passed me the baton and I

took over the responsibility as the General Secretary (Soc. & Cult.) of the Electrical

Engineering Society. Since then, it has been a great experience working under Prof. Kishore

and Prof. Biswas, to breathe some life into the Society and the Department.

The events that the society conducted this session mainly include the Dept. Trip to Kolaghat

Power Plant for the 3rd year UG and M.Tech students, Dept. T-shirt (I hope that by now all of

you have received your tshirts, phew!!! ), Dept. Footer Match (thank you Prof. Kishore and

Prof. Bajpai), Group Photograph of the passing-out students along with the professors, and

last but not the least – the Farewell for the “Batch of 2010”, jam packed with excitement

and fun, and a sumptuous dinner at the Vikramshila foyer to culminate it (sumptuous????

Well, that’s you who’ll decide).

A very important thing which happened this year, was setting up of the “Rohit Kumar

Scholarship” (a brainchild of Kshitij Khurana and Rohit Jangid) amounting to Rs. 12000/-

given to a 2nd year undergraduate student. In this regard, I would like to thank all those who

bought the Dept. T-shirt, as the profit which we earned from that has been utilized to fund

this scholarship.

Thanks for your contribution and overwhelming support.

I am obliged and grateful to work under Rohit (President – EE society), Kshitij and Bhaskar

and sincerely hope that the society grows and touches new heights in the years to come.

Lastly, I am deeply thankful to my fellow office bearers of the society – Avneet, Megha and

Shishir for the wonderful work, and to 2nd year members (especially Garvit) for the immense

help and support.

From the General Secretary’s Desk

I look back at the year gone by as my tenure comes to an end, I cherish the role that the

society has played to breathe life in the electrical department which in recent years

has focused more on excelling academically. Printing of the department magazine coincides

with the time when our seniors take their first plunge into the world full of responsibilities.

They have achieved extraordinary feats in academic and extra academic pursuits so far and I

wish them similar success in the future.

The past year has been very eventful including trip to the ‘Kolaghat’ power plant and the

football match that was thoroughly enjoyed by everyone in the Undergraduate, Post

graduate and Faculty groups. We have also successfully started a scholarship program in

Rohit’s remembrance to ensure that Rohit continues to inspire us and our juniors. All these

events and activities would never have been possible without the guidance and support of

the faculty members, especially Prof. Kishore, Prof. Karabi and Prof Sinha (Head) who were

very supportive and motivating. I thank them for their precious time and support.

I feel that the society has a great scope to accommodate more and more events of rich

diversity. I would love to see more social functions and a couple of competitions being

organized by the society while of course keeping in mind the busy academic schedule of the

department.

Not consuming more ink, I will end by saying this it was an honor to be working for the

department’s society. My association with the society has left me with many good friends

and many wonderful memories. I wish success to the society for the years to come. I thank

everyone and bid farewell to the final year batch on behalf of the EE society. May you get

the best in life!

Editor Speak!

I know, I know… its Editor ‘Speaks’. But I am the

Editor. And the Editor Speak!

I was always amazed by how Albert Einstein

explained his theory of relativity. He said that

it was all in the reference frame; you sit next

to a beautiful girl, and time seems to fly

away; sit next to a coal oven, and it just

doesn’t seem to pass at all.

This magazine is a testimony to all those

instances when the very same coal oven

magically turned into the most fabulous of beauties and distorted the perception of space

and time one has when he or she comes into this institution, a naïve (well mostly) young

aspirer.

For once, I do not have much to say. But I do have to say what this magazine is not:

This is not a platform where great scientific minds pour out their intrinsic knowledge of the

workings of nature and the mysteries of space, time and matter. That can be found in the

volumes of text available in the Libraries of the world.

What this is is a collection of a few thoughts and memories some of the people in the

department could spare. And to them I am grateful; grateful for the fact that they shared

their memories and thoughts with the rest of us, and helped make this magazine possible.

Some of you might be intrigued by the article Dr. Kishore has provided. Well, everything

apart, it gives a sense of urgency to the need for ‘green thinking’. That apart, I would

personally like to thank Mr. Nallan, the co-author for helping me, and quite a few others, in

the High Voltage Lab. That was one spectacle I shall remember for quite a long time.

Last but, well, far from the least, I would like to thank every single individual responsible for

the publication of this magazine. Dr. Kishore, Dr. Biswas, Dr. Sinha, Rohit, Souvik, Kshitij,

DebC, Ekansh, Avneet, Megha and Shishir, especially Shishr, THANK YOU ALL for your

support and undying faith.

Thank you EE Society, Thank you EE Department

Thus spake the Editor…

Experience at IIT Kharagpur There was a time . . . there was a time when all the flowers of the world bloomed together, the sound of sweet bassoons echoed pointing towards a profound change. Then . . . Then we came to IIT Kharagpur.

Though unusual, is it not true that a ‘new’ place speaks volumes about the older one you lived in? Home sickness! You miss your family. You find yourself in the company of totally new people, all of whom are staying in the hostels for the first time. And add to that the weather and the food, and you land up with nothing but nostalgia. But with the friends you make over here, it’s not a herculean task to come out of that very nostalgic feeling.

Two parts of the three syllable KGP life are the classes and the hostel. Classes- I am not worthy of passing a comment upon them, but they are, as it appears to me, just fine. The classrooms, they’re really superb. I can still recall the time when I couldn’t bend down my head as I just gazed at the awe of the Main building and the auditoriums of Vikramshila; then our old classrooms back home seeming like crooked cubicles.

Cleared JEE, so came in with a bloated head- but the exams were really tough nuts to crack. I didn’t really crack them; on the contrary, they cracked me. This was until mid-sem. Went back home to holiday induced alternations between eating and sleeping. Naturally, I put on some weight.

Then arrived Illumination and with it working all night to hit the gold. Working was not all fun but when the final judgment day came and we lit the diyas, it was a sight that one could fall for. End-sems dropped in and again, naturally, I lost the extra weight I gained. I got enrolled in NCC, so I had to attend its annual training camp. I run a dry mouth out of good words when I try to explain how many fans the camp’s DTL gained. I ought to tell, it’s a ‘never-to-come’ experience.

I can understand how many of you returned with great zeal after the holidays just to find yourself waiting in a line that grows in the front and not at the rear. Anyway, that’s over. The campus rocked with Spring Fest, not to mention the ‘hardly rocking’ bands that came, and ended with brilliant performances by Kailash Kher and Pritham. Backing up the festival mood, Kshitij made the whole campus mad and run after robotics, nightshift . . .

The sky here seems closer than in my hometown. Maybe, here the horizon has come closer or the time’s trumpets echoed much louder, lifting our ground to the horizon. Wishing everyone a healthy and happy semester, cheers!

Love (and Networks) ------------ Note: This is how (boring?) my life is, I am "writing about love" for a magazine! :| ------------ Q: When do you know you are in love? A: You can never know, you can just feel it. Four years at IIT Kharagpur has ensured that I do not feel love as a 'human', but four years at 'Department of Electrical Engineering' has ensured that I feel for love as an 'engineer'. I know what I am about to write is not going to impress any of my professors (nor any girl reading this :D ), but, they are not impressed with our academic performance either. :D

Here, let me illustrate how I can feel love as an engineer.

Let us examine a simple resistive circuit.

Surely, this cannot be love. That is not how it is supposed to be! A straight line? There

definitely must be something more to it. Let us try an inductive circuit.

Err...well this can never be love! True, this is often how some of the modern relationships

are. Decreasing with time, exponentially, until it reaches a zero value! Oops... something's

gone terribly wrong here. Surely, this cannot be true love. Let us try a capacitive circuit

instead.

Page 20: Dep Mag EESoc 2010

POWER 2010

20

This seems like a good plot. We can see that love is increasing progressively with time, and

the rise is exponential. But there seem to be two problems. First, it reaches the maximum

value only after infinite time (!!), and second, the rate of increase of the graph decreases

exponentially, so, the relationship seems to get sluggish after sometime.

Let me come straight to the point. An LC circuit. A resonant LC circuit. Here's what it looks

like.

Perfect! A charged capacitor of the right rating, coupled to an inductor of the matching

rating, and they fall in love. What follows is perfect resonance, in a beautiful sinusoidal

wave, going on forever. True, there ARE ups and downs, but love lasts an eternity. One's

weaknesses are complemented perfectly by the other. Everlasting support. Energy

transferred between them constantly. Forever. In Harmony. Never dies. That's love. True

love. And, if you look at that graph very carefully, and let your imagination flow a little, what

you see is this...

Love is in the air....

And all you need is love!

Love (and Networks)...

Aloo Chaat

India is countries of unity in diversity. We have 5000 different mother tongues, 22 or so official languages and so many different cultures.

India is a melting pot of civilizations yes I am ripping of that title from America. C’mon have you ever counted the number of societies and cults we have at kgp itself.

I guess what I am driving at is the fact that we have so much diversity everywhere even in food a country with so much diversity that there is no vegetable that can’t be grown here. But the only diversity of Indian gastronomy that the ammas like to exploit is the fact that we have 300 ways to cook a potato.

On my first day at the institute I a typical vegetable hater was overjoyed to see that the meal that day was potato based, thought myself fortunate when that happened the next day, gave up on mess food when potato remained all that there was for a week, now I am trying to make my peace with it the fat bully by picking vegetables out of the potato preparation. Ironically aloo parantha is still my favorite dish for it is the only thing that doesn’t contain aloo.

Once one of the students made the carnal mistake of questioning the antique tradition of adding truckloads of potato- the answer was if not potato than what else to prevent us from gorging down more food, the mess has a limited budget -there were some solutions but none worked.

In a test run they replaced the potato with excess spices so that people either did not eat any food or ate some and drank enough water to keep their stomachs full till the mess closed but then there are so many people here who love spices and the others just added sugar to it making the food edible enough.

In another test run they dropped a massive readily available insect in the main preparation making sure a large number of people saw it that meant a lot of people eating outside and those with weak stomachs puking inside. However, this plan failed in the long run as the stomachs grew stronger and people became less finicky; few more insect flashers were added and then back again to potatoes.

Probably I am just being paranoid the potato thing is no plot to make us look like potato, probably the recipe of paneer kofta does mentions the ingredients as 3 slabs of paneer and a truckload of potato or probably inedible food builds character and that is why people spend two years of their life slogging to come here and have it.

Listen to me cribbing on and on what an optimist might say here is that keep picking out the vegetables and the pretentious little portions of food that are created is what the rich call delicacies so enjoy the delicacies of Kharagpur.

The one with a thought… “This part of my life… this small part here … is called graduating!!!”

So here we are, brains and legs all stretched out on the damp grass of the golchakkar staring with blank eyes at the insti top under the vast expanse of the universe. Its me and my fellow graduates yet trying to come in terms with the fact that day has come when we would throw our caps in the air (and hopefully miss the dean’s head ) . A delirious, yet flattering thought suddenly crosses our minds “Friends, the world has discovered us…WHAT NOW???” And here goes the DILEMMA … “But, do I know where I am going? Do I even know WHO I AM ??? Oh Nooooooo!!!”

Well friends I hope you do not know! Well yes we are graduating but then we always are.

Newsflash: There is no such thing as Graduation friends, only a series of small graduations, continually.

Sometimes we throw our caps and other times we don’t. So let’s just sit back with our theme song once again and celebrate the chapter KGP of our lives. After all the midsems, endsems,vivas, cheddis, tikka , nightouts and most of all the bhaatbaaji the kgp experience just isn’t complete without the following activities–some are serious, some are fun, and then those others…well you can form your own opinions. So here’s a list of the top ten things to do before you put on that gown.

1) Lose your voice in a tempo shout. 2) At least 3 back to back night-outs. 3) A performance on the netaji stage. 4) Climbing on the highest table to light up the diyas during illumination 5) Watching F.R.I.E.N.D.S… all of it. 6) Spending a whole day at tikka chatting with friends (though CCD can be an

alternative in this weather). 7) Visit to the insti top.

8) A high 2.2

9) Climbing a water tank 10) Go find a date in kgp.

I AM YOUR FATHER AFTERALL…

Guddu was a small kid and much like his pals of the same age, he too loved to play football, cricket, basketball and other such playful games. He saw his friends playing and being mentored by their fathers, but unfortunately, his father could not play with him. Jatin, his father, had polio. For a stranger passing by, Guddu might be similar to any other boy of his age, but reality was far away from that. His mother was not living with him anymore. She had left home long back, as long as 5 years, when Guddu was at a tender age of 7.

His father suffered from polio in his left leg. Now Guddu had grown big enough to be a bit too embarrassed while moving around with his father, whether it be parks, restaurants, or other public places. Probably this was the main reason why his mother shunned both of them, she had a choice and made one, but little Guddu had no choice but to live with his father.

One fine morning, there was a knock at their door. Guddu was happily surprised to see a handsome, tall, stoutly built man standing in-front of him. He was so very astonished to see him that he just could not stop gazing at him. This young man was their new neighbour. How much Guddu wished that he would be his father. He got his new friend now and made all desperate attempts to find a father in him, a handsome one...

He would now prefer going out with Ravi, his new neighbour than with his father. After school time, his father would be waiting for him to return, but Alas! would find him sitting and chit-chatting with his new friend.

How much Jatin wished that he would spend the same quality time with Guddu. But soon realized that if Guddu was happy talking to Ravi and spending his weekends with him, he would do injustice to separate the duo. Days passed by and Guddu swayed further away from his father.

One night, Jatin thought that he should make a move and tell his plight to Ravi. Ravi after all was a good guy, and he thought Ravi would surely understand his condition. They both went for a walk. Guddu was sleeping in his room. No sooner did they go about just a mile, than they heard screaming of help from within the house. Jatin knew it was Guddu. They both turned round to their amusement. Their house was on fire!!! Guddu was out in the balcony and cried his heart out for help. Impaired leg made Jatin’s condition very difficult to help Guddu out. So he begged Ravi to go and fetch out his son from the rising fires. But Ravi was too scared to go in and risk his life.

Jatin had no choice now. He had to save his son. He loved him. Guddu was his only reason to live. Jatin could not see his son in that condition anymore. He quickly threw away his crutch and slithered his way into the house. He got hold of Guddu and wrapped him round in a blanket. He then slowly and cautiously brought him out in the open. Guddu had two protective layers, the blanket and his father’s embrace. In the meantime, Ravi called up the fire brigade and the nearest hospital for ambulance. Both Jatin and Guddu were admitted in

Page 24: Dep Mag EESoc 2010

24

it. There were minor burns which took just about a week to heal up, thereafter the two got discharged and were declared fit to go home.

Guddu was silent all this while. He spoke to no one, not even his father or his favourite Ravi.

Both reached home. They were both silent. Guddu suddenly broke the lull. He broke into

tears and heart rending sobs. He went to his father, stared at him for sometime, and then

hugged him tightly in his little arms. Jatin too could not restrain himself from crying. He too

broke down. They didn’t speak, but there was a question in Guddu’s eyes “Father, why do

you love me so much?” Probably the answer to which even GOD knows not...

The Tempo-Guy? Really???

I was surprised when I realized today that some people in the department perceive me as the tempo guy, and are even willing to club me with chams and ss. ;)

I want to put all these allegations to rest, once and for all. :P

Well, Bhaskar wants me to write this article on how I managed so many things at the same time; but let’s just get real, did I?

My CGPA has skydived ever since I entered EE, from 9.08 to 8.55 in a matter of 4 semesters. Let’s not talk about DR, that's even more traumatizing. So, clearly, I haven't done my studies properly. I am not a core-team member, neither involved too much in the hall, or in the gymkhana. No bandi, not even a banda. Music, and ETMS, are probably the only things I care a little bit for. Nah, I don't think I managed anything at all.

I think my lab partners know me best, and will testify to how peace-maroo I am. And Bhaskar, don't you remember the Basic EC lab? Don't you remember how many times you had to write the record while Diggi and I weren't doing a thing? And don't you remember how much you cared about all those resistors and their coloured bands while we didn't give a damn? How can you, of all the people, accuse me of such a heinous crime!

Okay, granted, I ask too many questions in class, but come on guys, classes are boring as hell, and if we don't even find stupid excuses to stall the professor, won't we die of boredom? Do you like their monologue so much that you don't want someone like me to break it? And don't you like it when I ask the professor to slow down?

And yes, you can accuse me of taking too many additional subjects, but trust me; it was not because of excessive tempo. It was, as I have told a few people, just because I was too lazy to go back to Azad during the breaks between lectures. So, it’s because of a lack of tempo, not because of tempo.

Looking at the above evidence, I sincerely request the esteemed court of law to acquit me with all due respect! :D

EE-Society at a Glance…

In the few pages of introduction right at the beginning, much has been said about the society. As an editor, I really do not have much to add to that, save maybe give a brief over-view of how the society fared in the past year. This is not in chronological order.

Soccer Extravaganza

March 2010. Excerpts from an article written by Suvankar Biswas (07EE1039): “…With an indifferent shake of my head, I also started practicing my favorite football stuff: free kicks. After 5 minutes, someone came to the field. It was none other than Prof. Kishore. All of us were looking at each other in sheer disbelief- it was

already 7.15 and only 3 of us were there; clear violation of “rules”!!!! However, Avneet arrived at 7.17 and saved the blushes of the society, followed shortly by Rohit Jangid. They had brought the refreshments and Avneet was in footballing attire, raring to go as soon as possible. However, it was a miserable turn-out… and Avneet and Rohit were soon calling every Batti guy’s no. they could find. But the professors had also disappointed. Only Prof. Bajpai and Kishore were

Page 30: Dep Mag EESoc 2010

there … The maximum turnout was from the 4th years; there were only 3 3rd years, some 2nd years. As for 1st years, it was interesting: They had a CLASS TEST….on ELECTRICAL TECHNOLOGY!!!! God Bless Batti!!!!”

“…So finally, our little get-together ended in the best possible way as we posed for group photographs. The camaderie in the match was wonderful to see. Even the unforgiving sun could do little to dampen the occasion. The event would be a memory to cherish for all the 4th years that played in that match. For us, 3rd years, we should organize more sporting events, and more importantly, our attendance should be higher. This particular event created a lukewarm impression among the passing out batch about us 3rd years, as regards to dedication. Finally more professors should also come to such events, to increase celebrity appeal. Anyway, this should be a motivation to us to organize such events in good spirit in the future, so that BATTI ROCKS!!!! All hail Batti!!!!”

The Department Tour

January 16th, 2010. An excursion to Kolaghat Power Plant An article written by Nivedita Patnaik, 3rd year, IE:

“7:00 AM Excited as some of us were for the trip to Kolaghat, it was too early by Kgp standards to wake up and be ready by then. The bus was already standing in front of the gymkhana, as intimated. But, again too early! 7:50 AM More smiles as the GSecs, Avneet and Ekansh, who had organised this trip arrived with refreshments for the journey. 8:00 AM – Finally, our journey began with Prof. Anirban Mukherjee, who had very kindly agreed to accompany

us. “ “…Next, the guide for the day; the guide would remind one of a class teacher chiding students for their misdeeds. This comparison does not go without reason as someone from our group got too excited after looking at the long stretch of panels and touched an indicator to take a closer look.(:P) We had a quick tour of the power plant, starting from the power plant followed by the boiler and generator unit, and the control room in succession. The power plant generated a total of

1260 MW from six units. Three of these units were housed together. The tour concluded with a visit to the coal handling unit. 1:00 PM We bid adieu to our guides and got back on the bus. A peculiar sight at the coal plant was the blackened surface of the flora surrounding the site. That must be quite usual given the huge amount of dust produced. 1:30 PM Lunch time. All of us were exhausted after the day long outing and we all settled for lunch. With the ‘tempo’ almost over, the return journey was a quiet one. While, Prof. Mukherjee collected the feedback about the trip, some others dozed off.

4:30 PM Kgp again. The industrial trip which was the first trip to a power plant for some of us was not only an academically enriching experience, but also an amusing one. It was quite a commendable effort on the part of the members of the Society of Electrical Engineering for organizing the trip. ”

Farewell Prof. Basu

Professor T K Basu was bid farewell early in the Autumn Semester. A small farewell was organized by the department society. A few pictures of the event and a few memorable lines from the event…

On career choices by IITians: “… The majority of IIT students should go for research or (sic) by research I do not mean the PhD programs only but R&D or Design where there’s a lot of intellectual activity, intellectual satisfaction… after all, you’ve been given a very specialized training, why should you waste your energy? You may get a lot of money, but you’ll never get job satisfaction…”

On the EE department in his student days Prof Basu recalled how once, during his college days, after the students came to (falsely) know that a viva had been cancelled, a lot of them decided to catch the train and go home. On knowing about this, the respective professor made sure that this situation was avoided when one student was‘re-called’ from the kgp station after a phone call followed by an announcement in the station was

made. And that’s not the end of it. A boy who made it to his home in Delhi was delivered a special ‘telegram’ which informed him of the impending viva to be undertaken. The chap took the very next train to Kgp. On being asked to describe Kgp and EE department “…My association with Kharagpur is for the last 46 years, so I just can not really think outside of Kharagpur. But of course, wherever I go, I make it my home… Here in Kharagpur, every brick of this building, this department is…(sic) I am a part of this whole building… I want

that our students should propagate the kind of culture we have developed here” A few lasting words “…It has been a really, really nice experience… I have learned a lot form the students… Kharagpur should be your home away from home…”

And of course, whoever can forget his golden words, imbibed in our minds for eternity: “Make friends, take part in games and activities, have fun, help each other out, once in a while even

Rohit Kumar Memorial Scholarship

“Grieve not, nor speak of me with tears, but laugh and talk as if I were beside you there.”

- Isla Paschal Richardson

It has been more than a year since that fateful Sunday in the spring of 2009 when something

very sad happened, so much so that its melancholy resonated with every single soul who

called him or herself a Kgpian.

It has been more than a year since a lot of us poured our hearts out, whether it was in the

hushed settings of classrooms, or in the crying masses of solidarity.

It has been more than a year since ‘he’ left us, left a lot of us with fond memories, with

broken hearts and tearful eyes.

It has been a long year, for a lot of us…

Being one of our own, one of the members of our small EE family he must have had similar

dreams like all of us, maybe much higher than some of us could ever imagine. He left with a

lot of promises unfulfilled, promises made to his family and friends.

This year, the Electrical Engineering Society established a scholarship in his memory, one

that was to be awarded to a second year B.Tech student from our department on the basis

of his/her overall performance in IIT Kharagpur over the last two years. The awardee was

decided by Dr. Kishore and Dr. Biswas, and a certificate along with a cheque of Rs. 12,000

was awarded to him during the farewell ceremony.

This Year’s recipient of the ‘Rohit

Kumar Memorial Scholarship’ is

Mr. P Bala Kameshwar.

It is hoped that in some small way

we, the Society, can contribute

towards making sure that Rohit’s

memory lives on, that he inspires

us now and in the future, that he

inspires the ones who shall one

day proudly call themselves

students of EE Dep. or IIT Kgp, in

the very same ways as he had

once inspired us, his friends, and

put a smile on our faces.

Abstract—The dawn of industrialization has forced

many to adopt techno economic feasibility studies on

green energy. Rapid surge in both subscribers and

digital data content is stressing the wireless

infrastructures. As more data traffic demand is

placed on limited amount of wireless spectrum and to

reach the urban population, the mobile service

providers are forced to use more Power Amplifiers

(PA’s) in Radio Base Stations (RBS’s), which consume

more power. Apart from increasing the total energy

and operational costs, they account for large emission

of Green House Gases (GHG’s). This paper addresses

the feasibility studies to use alternative energy sources

for powering a Telecom tower for future data

communication in order to reduce the green house

gas emissions, a contributor to global warming.

Index Terms— Digital data, Industrialization,

INTRODUCTION

ENEWABLE energy sources are attracting

major concerns for their availability in

abundance, and being clean. Their popularity has

skyrocketed over the last 5 yrs due to the

diminishing supplies of the other conventional

power sources like coal and natural gas.

Conventional fuels emit GHG’s and pose a threat

to life on earth by steadily increasing the acid

deposition over the earth’s surface. The need to act

fast is due to the drastic increase in the number of

mobile customers over the past years [1]. Among

the most widely preferred systems of alternative

power, Photo Voltaic (PV) systems have gained

large popularity as nature has abundant fuel to

power them. The present day scenario depicts the

sparse usage of PV systems mainly due to its high

initial capital involved. Non conventional energy

sources are most promising candidates for

Research and Development which can trigger a

revolution in future for low cost fabrication of

these devices. PV systems find various applications

ranging from powering house hold loads to aiding a

soldier in remote fields. They can also be used to

power vehicles like solar cars to light aircrafts,

satellites and spacecrafts [2]-[6].

In order to cater to the needs of a variety of

customers, including the ones in the rural sector,

mobile operators are beginning to establish their

networks in the rural sectors. It is obvious that,

rural sector population is worst affected in terms of

the reliability of power supply. Under no

circumstance a telecom station can not be

compromised for an interruption in service. The

foremost concern of a telecom station is to provide

reliable service for its customers for which reliable

power is mandatory. The backup power supply

equipment like the Diesel Generators (DG’s) apart

from being very costly also have detrimental

effects on the environment. The answer to all these

is readily available with Nature.

Due to the high initial cost involved in

establishing a PV system, it calls for optimization

of power output at all times. The designer should

be conscious to design a network keeping in mind a

scheme for the future demands; else by the time the

new network gets deployed, it becomes obsolete.

A press release from a noted major wireless

service provider ERICSSON in June 2008 states

that, an average GSM subscriber is responsible for

the emission of 25 kg CO2 [7]. In response to these

annoying figures, and to realize an energy efficient

radio for next generation mobiles communication,

green power solution is a mandate for the

Vodafone Essar project at the Indian Institute of

technology Kharagpur, India. In the new generation

systems, there is a good amount of decrement in

the amount of CO2 emissions in comparison to their

first generation counterparts which emitted over

180 kg of CO2 annually, but on a global scale, the

effects are still not appreciable [8]. To get an idea

of the extent of emission, an average automobile

consuming 10.5 litres of gasoline, over 125 km

emits 25 kg of CO2. A prelude from literature

concludes that the greenhouse gas emission from

the Information and Communication Technology

(ICT) equipment is about 2% of the global figure.

If this trend persists for another decade, it is sure to

catapult the emissions of green house gases. Figure

1 shows the statistical breakup of the ICT

equipment emissions as a fraction of global green

house emissions [9].

Fig.1 A comparison of global green house emissions and

emissions from ICT [9]

With demands continuing to rise, it is foreseen

that the future goal of throughputs over mobile

network would be a prodigious 300 Mbps [7]. For

this goal to be realized, the service provider should

adopt alternate energy sources like the use of Fuel

cells, Solar power, stand alone wind power systems

etc, without which the power demands from the

traditional coal based power plants will increase,

which will lead to dangerous levels of global

warming. Figure 2 shows the percentage of power

consumed by various ICT equipments [9].

STAND-ALONE SYSTEMS

PV panels

A solar-powered telecom station is projected to

operate in a remote rural environment, where

typically there is no or deceptive provision for grid

power available. At most, it can be assumed that,

the telecom base station has ample backup power

to sustain itself for 3-4 days in case of weak or no

recharging capability.

A PV panel depends almost entirely on the

primary source for its power output, i.e., solar

insolation. Since the solar insolation varies with

time and because the PV system itself has a non

linear voltage-current characteristic [10] depending

on external parameters like wind, rainfall, ambient

temperature, dust, load etc, the PV panel if

operated along with an efficient dc-dc converter

(Buck/Boost/Buck-Boost), can ensure efficient

operation by operating the PV panel near its

maximum power point. Depending on the load,

strings of panels are arranged in series of parallel

sets or number of strings in parallel. When PV

modules are integrated with other alternative

sources, safety takes prime priority. A system is

designed such that under no condition, the PV

panel gets reverse current from the DC bus. This

may happen when the battery is over charged due

to the excess solar insolation or during light or no

load conditions, when the energy obtained is not used by the load.

Fuel Cells& Batteries

Fuel cells are most suitable for applications with a

power demand lower than 10 kW and energy

demand larger than 10 kWh [11]. An overview of

the fuel cell technology is described in [11]. Fuel

cell power sources are maintenance-free and they

are insensitive to both high and low temperatures

and have long lifetime in standby mode [11].

Fuel cell systems are transparent and can be

monitored remotely [11]. The stored energy can

easily be measured from the pressure of the gas

cylinders. The efficiency (hydrogen to electricity)

is predictable. Due to this, the energy content can

be expressed using units kWh or Ah. On the other

hand, the status of batteries is significantly more

difficult to measure. The uncertainties involved in

predicting the capacity reduce reliability. In order

to secure high reliability, the batteries are replaced

long before the problems occur, which adds to the

cost.

Fuel cells can operate at high ambient

temperatures, atleast upto 50°C. No degradation

occurs even till 75°C. Batteries start to degrade at

these high temperatures [11].

Fuel cells are capable of operating at extremely

low temperatures. For example, Cellkraft’s system

can operate from -33°C [11]. Moreover, there is no

reduction in energy output of fuel cells even at

subzero conditions. The capacity and available

effect of batteries is significantly reduced at cold temperatures.

Page 36: Dep Mag EESoc 2010

POWER 2010

Diesel Generators (DG’s)

To meet high load situations, running a DG is not a

wise decision, because the cost increases with the

capacity of the DG. When the equipment consumes

less power, the use of DG is well augmented,

because the cost of the DG is directly related to its

capacity [11]. If the power supply model is to be

designed completely “green”, then DG also should

be compromised, because the fuel used to power

the DG will perish with time, and the power from

the DG is accompanied with a small amount of

greenhouse emissions. DG’s should be

continuously heated by electrical heating to be

ready for start-up in cold conditions [11]. Fuel

stored in a DG can be measured, thereby reducing

the uncertainty and increasing the reliability. DG’s

work well in high ambient temperatures, if the

cooling system is properly designed [11].

HYBRID SYSTEMS

As the name indicates, hybrid design is a

combination of two or more alternate energy

sources. Solar powered systems provide a modest

but a costly solution for an energy crisis prone

telecom sector and when it is used alongside other

cheaper power sources, it becomes economically

competitive. A hybrid power system can be

designed depending on the deployment scenario.

To meet high load situations, running a DG is not a

wise decision, because the cost increases with the

capacity of the DG [12].

For fluctuating loads, a hybrid system with a PV

array or a fuel cell system can be configured so that

the DG handles pre-calculated optimum load

power, and the solar-powered system or the fuel

cell system shares the balance. In this way, the

hybrid system is optimized, and it improves the

efficiency too. Figure 3 shows a typical scheme of

a hybrid model consisting of a PV array and a Fuel

cell [13].

The main motive of a hybrid model is to realize

an uninterruptable supply for the telecom station

independent of any external (weather) fluctuations.

The module design is given for AC and DC loads.

A suitably designed inverter can supply AC loads

too. The charge control system operates the entire

system close to the maximum power point. The

switching instances are so fast that the load current

can essentially be assumed constant. It essentially

switches the circuit ON/OFF to track the peak

power. The level of voltage can be bucked down or

boosted up accordingly using a suitable

converter/inverter. The scheme in Fig.3 boosts the

voltage level. The optimized combination of the

weather dependent solar PV modules and the

weather independent Fuel cell modules delivers

uninterruptable power supply.

Fig.3. Schematic of a Hybrid PV-Fuel cell system [13].

OPERATIONAL CHALLENGES

From an operational view point, a PV panel

experiences large variations in output power under

variable weather conditions. This calls for a novel

power control algorithm in order to supply

maximum power all the time. Another important

challenge is to model a Maximum Power Point

Tracker (MPPT), so that the PV module operates

always near the peak power point. This facility

enables the device to shift the angle of inclination

in proportion to the angular distance travelled by

the sun from dawn to dusk. Reference [14]

addresses various different ways of tracking the

Maximum Power Point.

In comparison to all the conventional methods of

tracking MPPT, Hill Climbing / P&O algorithm

has gained a distinct advantage over the others as

its very simple. The algorithm works on a basic

philosophy of Perturb and Observe [14]. Figure 4

shows the characteristic power curve of a PV array.

The MPPT Hill algorithm involves perturbation of

the duty cycle of the power converter. Perturbation

in the duty cycle perturbs the power drawn from

the PV array, and consequently perturbs the PV

array terminal voltage and PV array current. Figure

4 shows that incrementing/decrementing the

voltage increases/decreases the power when

operating on the left of the MPP curve and

decreases/increases the power when operated along

the right of the MPP. Therefore, if there is an

increase in power, the subsequent perturbation

should be kept the same to reach the MPP and if

there is a decrease in power, the perturbation

should be reversed [14].

POWER 2010

37

Fig.4. Characteristic PV array Power curve[14]

The next major challenge is to store the excess

energy when there is surplus.

The other option is to integrate PV panels with

other alternative sources of energy like fuel cells

[15]-[16], and diesel generators (DG’s) [17]. PV

panels can also be integrated with secondary

energy storage systems like super conducting

magnetic energy storage (SMES) systems [18], and

battery energy storage systems [19]-[21].

Integrating PV panels with other energy storage

equipments in the system demands appropriate

power control.

In case of standalone Fuel cell systems, a rapid

increase in the load power would result in a

significant decrease in the fuel cell output voltage

[13], which would deteriorate the power quality or

sometimes even render the fuel cell system useless.

This happens because the fuel cell essentially

operates on the synchronized control of number of

valve openings and closings. Due to the slow

dynamics of the valves, a sudden surge in power

demand cannot be met by a fuel cell. This is

basically because of a difference between the

mechanical time constant (in seconds) and the

electrical time constant (in milliseconds).

The fuel cell system has to be oversized to meet

the peak power demands. To increase the response

speed and peak power capacity of the supply,

auxiliary energy storage and corresponding power

conditioning devices and control mechanisms are

essential. This also negates the disadvantage of the

fuel cell system which has slow dynamics. During

transient power demands, a novel control

mechanism should be adopted such that, the battery

supplies the bulk of the power demand, as its time

constant is less. After the system voltage

characteristics recover, the fuel cell can start

contributing its part.

Although, batteries are used to store the excess

energy when the load is low, or to power the

system when there is no input power, the cost of

the batteries themselves is expensive. So, proper

care should be taken to design the secondary

storage system in case of primary input power

failure.

A separate control mechanism for checking the

battery voltage levels should be employed.

Otherwise, the battery which is directly connected

to the DC bus might over charge because of light

load conditions. The voltage control mechanism is

basically established by controlling the duty cycle

of the PV panel output current [13]. On the other

hand, when the voltage level of the battery is below

a specified level, the control mechanism forces the

MPPT to come into operation so that the PV panel

is forced to operate at maximum power point. A

very efficient algorithm based on state estimation is

reviewed in [13].

When the systems are integrated, there is a

hidden problem of insulating the various

subsystems. Proper care should be given for

protection of equipment too. There are chances of

reverse currents flowing from the fuel cell stack to

the PV panel, which may damage the PV panels.

Therefore, diodes should be designed carefully,

interrupting any reverse currents along the DC/AC

bus.

The use of high performance power converters to

supply different types (AC&DC) of loads, and the

appropriate usage of control techniques can supply

high quality power. Control strategies for power

conversion and power quality on single phase and 3

phase for PV applications are reviewed in [22]-

[23].

CONCLUSIONS

A properly designed Hybrid system, can give its

designers a run for their money. It’s worthwhile to

design an integrated power system that combines

the energy density of the Fuel cell or PV array and

the power density of the storage batteries. Further,

a low electrical time constant system must be

integrated to supply sudden increase in load

demand and a larger time constant system like the

fuel cell system can supply a constant load.

Integrated systems require high performance

converters to control the charge flow through the

DC bus, thus enabling reasonably good power

quality. Proper provisions of safety also should be

dealt with, failing which the costly equipments like

PV array will be damaged. If a PV system is

considered, the location of the site is of prime

importance as the solar insolation depends on the

actual site of deployment. With all these taken care,

one can be assured of a nearly reliable power

supply for the future telecom communication

towers.

“If it weren't for electricity we'd all be watching television by candlelight.” -George Carlin

Viva La Vida This was inevitable. It had to be. This article, this piece of my mind had to come. It has been said

before. It has been whispered into the ears of the disciple and screamed in the nightmares of the

terrorized. It has been the subject of fantastic parodies and fanatical studies. It has inspired the

creativity of the eye of the mind in conjuring up visions of how one shall meet with it one day. And it

is not so much about the meeting, but the walk and the preparations en route, one that spans nearly

four years, beginning in the chambers of roaring mighty beasts, and ending in the hallowed corridors

of a department that earns your respect, one way or the other. It is about the journey that starts

between the whirring of machines and ends in one of the most legendary events of Academic Life in

IIT Kharagpur.

Of Labs

There is too much, just too much to write here. One can write a book on the stories of laboratory

experiences one hears, and even then, one will find a shelf filled with such books, every new one

springing a surprise the previous one denied. And hence, I shall restrict myself to what I’ve heard,

experienced and remembered. If any professor per chance reads this, I have this to say: You are the

stuff Myths are made of.

And it all began in the first year, with that lab in the ground floor of the EE Dept. I distinctly

remember the day; it was the first lab session in the Machines Lab in the Spring Semester of the

academic session of 2006-07. Prof. A K Sinha, the current HOD took our attendance, sorted us into

groups of four, briefed us on the purpose and maintenance of LAB records and PT sheets (I still do

not know the right spelling) and the need for wearing shoes, and briefed us on the basic electrical

measuring instruments to be used in the days to come. I was a keen listener back then and had no

inkling that I was fated to be hurled into this department and that our destinies would be

intertwined, me and that very laboratory, or that the briefing received just a few moments ago

would be the Holy Grail of Lab Etiquettes. And then came the second lab session.

Of Vivas

I do not expect a lot of the freshmen to be as well versed in the concept of daily vivas as I was back

then, owing mostly to my previous school. But boy, did I find myself unprepared. Though it would

not happen to me till the second semester of the third year in that very laboratory, I was to view the

spectacle of confused students being sent out of the lab for various reasons, whether it was the lack

of shoes or the poor quality of drawings of circuit diagrams. But the one thing that stuck, a

permanent vista, was the unnerving of even the most hard-boiled students at the sight of the

professor approaching for a viva. Whether an instantaneous 200 V DC at the experiment site, or a

prolonged 11 kV AC at the professors’ tables, the shocks never seemed to lose their charm, or the

effect they had on us. And the terror of the first year, which I was pleasantly reminded of only a few

days earlier in my GV, was the Tube-light Experiment.

Of Tube-lights and Folklore

The tube-light experiment was a part of

first year folklore. It was what would

become the stuff of nightmares for those

giving a serious thought to the final ET

lab viva preparation. I was pleasantly

reminded of this fact when Prof. A

Mukherjee asked me about the setup of

a tube-light’s circuit in my GV. Ironically,

three years back it was him taking my

First Year ET lab viva, and back then he

had totally overlooked this question.

For some reason, the tube-light

experiment was an indicator of what was

to come. People panicked, went around asking others and were all too flummoxed by the very

nature of topics and vivas. There were plenty of stories that students were being told that they

‘weren’t fit to clear JEE’ or that their lab files were being hurled hither-thither. It was then that I

discovered the power of the ‘Internet’ in general and ‘Wikipedia’ in particular. They have been life

savers on more than one occasion.

And then, there was the ‘folklore’.

The Department of Electrical Engineering, or, more popularly, ‘Batti Dep’ , has been a source of

innumerable myths and legends from the moment I set foot in this college. The very mention that I

belonged to this department brought smirks and sighs alike, and created an image which was to

become a part of my identity (and maybe of a few others).

From ‘Epic vivas’ to ‘ruthless maintenance of PT files’, they were to become a part of our daily

routine for the next 30 odd months. While the whole issue of file maintenance assumed a whole

dimension of its own, from penalties for late submission to whole night-outs of figuring out what to

Page 43: Dep Mag EESoc 2010

POWER 2010

43

write in the first place (not to mention the emergence of human xerox machines), the labs

themselves started becoming storytellers of epic proportions. And then came… the SYNCHRONOUS

MACHINE.

Of Synchronous Machines and the General Problem of Synchronization

If there is one experiment I personally can boast about performing even while taking a nap, it’s the

Synchronization of the Synchronous machine experiment. Deriving solely from my personal

experience, an experiment which was performed in at least two different lab sessions removed by a

year, it has to be the one experiment which, in the past four years, has brought more students on

the verge of ‘I’m definitely failing this lab test’ attitude if nothing else. Personally, it was nothing

short of a miracle that my group (Debanjan Bhowmik and Amulya Srivastava) was able to complete it

for the first time after 14 grueling hours (yes, I remember the number) of lab sessions and God

knows how many sacrifices (of measuring equipment).

But I believe that somehow

the problem wasn’t that

experiments were too tough.

I believe it had more to do

with the general

synchronization with the

degree of attention

demanded by the subject, or

the lack of it thereof, which

caught students off guard on

most instances. There have

always been the more careful

ones (easily branded as the

‘muggu’s) who have generally

performed better.

However, notwithstanding these facts, there have always been moments which have generated

extremely opposite reactions in the students and faculty. Out of the many that I remember, the one

that I find worth mentioning is that of Shobhit Singhal. The young man under consideration has

single handedly achieved feats in the laboratory which most might decree as impossible. But the one

I shall mention has captured the imagination of yours truly for ever.

It was in that very machine lab when I and my group were working on the transformer, performing

the open and short circuit tests, that all of a sudden the whole room came alive with a brilliant white

flash. Prof. Dheeman Chatterjee rushed towards the site of the blast which, to my surprise, was

Shobhit’s experimental setup. Later on, after the lab session, I found out, from word of mouth (that

being mostly Shobhit’s) that in the experiment, a rheostat had to be connected to the voltage source

as a potentiometer, and hence both its terminals needed to be attached to the primary voltage

source. While one of his lab-mates started at one end of the circuit, the other started at the opposite

one and Shobhit got busy with the rheostat. After all three were done with their parts (which

included Shobhit connecting the rheostat to the rest of the circuit), our hero switched on the power

which, by now that it is obvious, was connected only to the rheostat. The rest, I leave to the reader’s

Page 44: Dep Mag EESoc 2010

POWER 2010

44

imagination. By the way, this very same champion of ours managed to blow up the power supply of

the entire lab during a certain lab test.

Moving away from lab tests and PT files, there were always the vivas. The thing about the not too

illusive ‘viva’ was that it was very ‘professor dependent’. If you were lucky, one panel of professors

might let you live with your poor preparation. On the other hand, a certain other panel might not

even spare the most seasoned of batti-geeks. And this brings us to the famous and dreaded Controls

lab.

Whoever has done any experiment

there will surely remember the

general commotion around the

inverted-pendulum experiment.

And then there were the Vivas of

this lab. This was the very lab

where I first got face to face with

the famous ‘why are you even

studying in IIT’ statement. And now

I know that it had a lot of reasons

behind it being hurled at me, which

included my preparation not being

up to the mark. But then my

Professors in-charge were Prof. J

Pal and Prof. B M Mohan. Well,

that’s enough for a hint.

But enough about all these labs and their vivas! Let’s move on to the big fish.

Of Grand Vivas

For a change, we weren’t alone here. Every student in every department had the same expression

on his or her face as the one I had been seeing in the mirror for the past 3 years. And then, there was

the moment of reckoning. Four students in Energy had already received ‘Re-’s. After a day of staring

at the books and realizing that it wasn’t humanly possible to study all that in the short span of a day

(which generally seems enough to dish out a whole BTP presentation worth a semester), I sought

refuge in the infinite knowledge of R Vignesh and Anuj Gupta (who were also my saviors the past

four years) and by my side was the trusty Shobhit Singhal. After a stormy session of numbers and

figures, I rushed headlong into the viva, and before I knew it, it was over!

After four years of unending, unnerving and unbelievable banter about the grandeur, the epic

magnitude and the sheer exhaustion of GVs, it was over… just like that. And to add to that, they

served us Frooti and sweets during the viva! It was unbelievable. I managed to answer questions

(albeit a few), and when asked my favourite subject, I did what I had waited to do for the last 3

years; I blurted out “literature”. And, guess what, I got away with it! (Although, as an after thought, I

do believe it had more to do with the fact that the question was asked after the viva, but

satisfactory, nonetheless.)

Of Farewells

No, no, no… This part has nothing to with the department farewell. That’s another affair to be dealt

with in another place. But it was a little sad, saying good bye to vivas. Though, at the time of writing

this article, I’ll still be left with one impending viva and the BTP presentation, but it was a different

thing altogether, facing vivas. I remember the words of an ex-student: “Attending the vivas in EE

dept has made me immune to the questions of interviewers.” And I guess it stands true for a lot of

us.

But then, I have written enough.

For now, let this monster of mythology take a rest. Let it go back to sleep, for next year, it has to rise

again, and plunder the sleep of quite a few. And oh! What a journey it has been…

Telling a Story…

“Sanjiban.... you are someone who I think ... is capable of saying a lot ... but saves it up” - Kshitij Khurana, drunk, Shankarpur

It’s funny how little you have to say when you are too busy thinking. It’s even funnier how one has thought away four years. I guess it’s high time I got this out, because I really don’t plan to “think” too much in my fifth year.

The most random place to start would be by saying I love the sea; preferably in the crazy-splashing-around-in-the-water way, not to offend hand-holding-sunrise-gazing couples. I guess specifically I love the water. That’s because the water remains the same ... freezing cold ... even when the people in the water changed over the years from the awesome ROBOTIX family, to the ex-girlfriend, to Singla banging Bhowmik with a beach ball. The water is always predictable.

I believe in enjoying laziness and not over doing it, where laziness implies not getting up off one’s bed and ensuring that one has enough seasons in his HD to last forever. Laziness does not include sleeping. It includes attending just enough classes so that you are bordering the danger zone, so the professors never knew you existed. The John Doe who got an Ex. When you overdo laziness, you get into trouble. I mean “G.D.Ray” kind of trouble. Then you become a nine point someone trying to save himself from getting kicked out of a course.

Laziness should never kill the adventure junkie that we all are. It’s not possible to scrape through the eternal boredom that enslaves you for four years without the adventure. With all the motors, machines, signals, wires and ... transformers.... things like that can permanently “break the spirit of your soul” unless you have a spark of adventure in your heart. It may be creating something new; it may be meeting that someone 150 km away or it may even be that week long road-trip where it was just you and your backpack. It’s not the adventure that you cherish, it’s the times you thought about the adventure and how it saved you from learning how to change the poles of an induction motor.

Laziness should never ever make you numb. If you become numb, then they won, you lost. Every viva you gave that made you feel bad, every pt sheet you bought that made you curse, every lunch you skipped to write that report and every coffee you had at 5 p.m. when your will to live has almost gone – remember those times. That pain, that frustration, that little indomitable fire is ... us. That pain accumulates to this finite burden that we can always carry with us. I would never give up those memories for anything in the world – maybe because those miseries brought about the best of friendship and the most precious of all memories.

I will never forget Kranti. I think it because he was always did the most fascinating of all things. I remember there was this switch in an experiment where the bulb uses to glow even when the switch was off (due to some internal wiring). Kranti was convinced it was some trick, so when i asked him “Kranti, is the main line disconnected?”, he proudly lifts the switch, sees the bulb still glow, assures himself his eyes are playing tricks on him and says “Yeeees”. Now as soon as I touched the wires – well not only did my ears jam shut, poor

Page 47: Dep Mag EESoc 2010

POWER 2010

47

Vignesh who was touching my shoulders got a shock through me as well. Prof Poddar came with a sheepish grin and said “Kranti......”

I will never forget Vignesh. The picture of Garfield with the “I hate Monday” speaks volumes about this guy. However something about lab reports, vivas and semester exams would turn this guy on. If a professor asked Vignesh during a viva, “Spell Arjun”, Vignesh would recite the entire Mahabharata. Though, it’s sad to say that Vignesh’s exotic charms did not work on one professor. After he laboriously explained how an inverted pendulum works, nodding his head and flipping his fingers, Prof S.K.D aptly concluded he was full of crap, and Ganesh and I were buffaloes in the crap. Abir was a buffalo outside it.

I will never forget Abir. When united with Bhomik and myself, we became the three bongali idiots. I was mostly a silent observer on their myriad of conversations on closed loop feedback, professors, universities, girls (lack of girls), politics, Saurav Ganguly and occasionally their outlook on life. For the record, here are things you may have not known about them – Abir had a girlfriend, wrote a poem, was and is still an awesome football player, fought his way through a life threatening problem, worships Scarlett Johansson and so on... Bhowmik is a self proclaimed narcissist, who cannot change a tube-light, loves Guinness, unsuccessfully attempts to build a body and calls himself the chosen one.

I regret that we couldn’t all know about each and every one of us. You breathe the same air for three years and all you are left with is a vague memory of a face and a horribly wrong stereotype to go along with. Many of us do not know about Shouvik’s compassion – how he is enabling the dream of a school kid; many of us do not know about Garg’s integrity – how he always thinks about doing what is right; many of us do not know how Anuj got angry the one time when Bhowmik drove him insane with his 8052 project. Then again I hope it’s never too late to know one and another. For the record ... I love reading Stephen King books (not for the horror but the philosophy of horror), and Ayn Rand (not for the philosophy of the character, but the characters themselves), love writing poems (yes you can use my services), am a textbook Pisces, spent 3 years in UK and I love robots.

Now, this last part, this is for Khurana. This is what I have been saving up. For a long time I didn’t know it was that drove me to do what I have been doing for 4 years now. But then last summer when I went to CMU, I came to know about this fascinating man who was everything I wanted to be. He was the late Dr. Randy Pausch. For those who haven’t heard about him, please look him up. He passed away at the age of 47 in 2007 due to terminal cancer. His last lecture is available on YouTube which is called “Childhood dreams and enabling the dreams of others”.

My childhood dream was to make something out of my own two hands. The day I learnt how to make a motor go forward and backward, my dream was complete. September 2006. From that day on, I wanted to enable the people who had the same dreams as mine. From then on the journey took me through hardships and running around and learning and teaching, from trying to teach my first year batch mates AI (an epic failure that was), to teaching first years to make robots, to giving lectures in Bhubaneshwar, Delhi, Pilani to finally January 2009 – when you look out and you see 3000 people from all over India whose dreams we are enabling. And then ... when most people decide to quit, I wanted to go on enabling – because four years down the line, there is a pride and an ego. I just hope no matter how much you may loathe the department or the institute; you have the pride of

Page 48: Dep Mag EESoc 2010

POWER 2010

48

having made a visible dent in people’s lives and in their heart. I also hope you have an ego of surviving it, the labs the vivas, the professors - because everyone has had a time where we thought we just couldn’t make it.

Don’t ever wonder why you were here, or whether you are meant to be here, or was it just one BIG mistake – it wasn’t. Whether you believe in God or not, it wasn’t a coincidence. I missed my department change by 0.04. When I went to Prof Kishore to change my lab grade from B to an A (like it should have been done), he gave his signature smile and said – “You are in this department whether you like it or not. Accept it”.

AND YOUR BIRD CAN SING…

Some of my experiences here in IIT are nothing short of being best entries in fmylife.com (its an awesome website, whenever you feel bad about yourself check this out, so that you can laugh at other peoples miserable lives).

1) Language barrier is one of the main problems for me, so it turned out to be pretty funny some times. It helped during OP, I used to stare at them innocently when they were shouting at me, once one of my seniors asked me "kya hall hai?", and without hesitating I answered AZAD. I think it’s funny. **

2) When I was meeting my guide for my btp, he asked me what languages do I know, I said, English and Telugu, he then asked "programming languages" laughing at me. Quite an impression I made. also he asked me why I was interested in control system and my grades, I said hesitantly D, thinking that my grade can be P. but my actual grade is C. this encounter is a true fmylife moment and I hated myself.. But he did accept me to guide. I do like control systems.

Ok now jokes apart, the best thing that happened to me in IIT is my seniors (T.Theja, Kumar Anubhav and Rajat Sethi specifically). Albeit I sucked at studies I think I learned a lot here, met some really interesting people. I would like to call my B.Tech as a 4 year sabbatical, so I am good to go for the next 20 years.

To Profs: I feel really guilty seeing how dedicated some of you are, but I promise you that I’m not going to let you people down. I’ll try keeping those words on main building in my mind.

To the 50 girls of ‘06 batch: thanks for being in IIT and acting as a glimmer of hope. You people seem really nice. So I would like to dedicate this song "hey soul sister" by train… :P

“It has never been the choice of even the wisest”

It happened, when in our second year, I was fated to be Khurana’s lab partner. Giving the

perfunctory glance at the lab manual unwillingly, and a cursory attention to the esoteric

paraphernalia (to me at least) of the department, we ironed out to elope as soon as the

professor lost sight of us and we succeeded. It would have been a home and dry coup, if the

professor didn’t have eyes for us, Khitiz and Sapnil, that very day. Alas! He called our names

after coming back from Nescafe. After the momentary lull, he pranced towards Monika’s

table and asked-

“They are your friends, izz it not?”

The mademoiselle completely entranced by the odds and ends of the equipment, turned,

uttered a “YES” and went along again. The poor 5th year of my hall, who helped us flee the

two gloomy hours, got a sharp reproof, nonetheless. The day ended.

The next lab, he announced a surprise VIVA, and the two of us were aware of the sequence

of events to be followed. With a wicked grin, he called us and offered us seats. I, if nothing

else, could remember the names of the experiments and the basics of each. Khurana, on the

other hand, could simper really well at the professor. Now the session began and rapid

questions were thrown, in so very the same fashion EE Profs follow, in order to seize every

opportunity of “khulle-aam” censure. I managed to parry off a couple of the bursts and

Khurana managed to maintain the same upward curving of the corners of the mouth. When

the contorted facial muscles began aching, the fellow yielded to the Prof and said-

“You know Sir! I was never made for this department. I had, like zero interest in EE. I had

aspired to be in the field of finance and accounting. It is too difficult to manage the courses

you have so little interest in. The problem with me is too difficult to explain.”

The slushy speech melted the petrified heart and the ‘figure of bravado’ succumbed-

“You know, you nebher get what you want. I too nebher wished to enter in this field of

laphtops and flaas-dribhes. I was also interested in some thing else. I understand how you

feel and I am so sorry phor you. Try not to lose your heart. Look at me; you cannot say ki I

was not made for this department, izz it not?”

What electrical department did for me?

I have faced numerous interviews in my fourth year and there has been one question often

asked; how do your electrical engineering studies come in useful for this position? At such

times, I often have given some really clichéd answers like ‘the analytical skills from

engineering would be applied later on’ or ‘ I now analyze pros and cons of a situation just

like the stability vs. the gain issues in control systems’. I have never spoken the real truth in

those interviews. The real thing is, now I can face interviews with much less anxiety. I would

not be exaggerating when I say that I was more terrified of my machines viva than my

Ahmedabad interview. Perhaps this is because ab to maraane ki aadat padh gayi hai! So

farak hi nahi padhta :P. On a serious note, our notorious vivas really give a good feel of the

so called ‘stress interviews’. I am writing this at a time when I am yet to appear for my GV.

Let’s see if I say the same thing after that. :P

Then one new thing that I have learned is to sleep with my eyes open. I have applied this to

good effect in my power system protection class . I hope this super-cool and useful

learning would come handy later .

Then there have been really wonderful people I have met in my department. One thing that

I really like about our department vis-à-vis some other departments (read THOKA) is the lack

of bong maggu culture in batti dep.

But one thing that still scares me: PT sheets. I still am very very very very reluctant when it

comes to writing those damned things. I am pretty sure, everyone would agree. Let’s hope

aane waali naslon ko wo na likhna padei.

In case my juniors get a chance to read this, I would just like to give one advice. Have fun in

labs, they are a very good learning opportunity, considering you get to deal with real stuff.

And find a person jiske notes ko aankh band karke trust kar sako nd padh sako (just like we

found Guptaji).

(Editor’s Note: I hope Aditya finds plenty to learn in the IIMs also; the man leaves quite a message for

the ‘aane waali’ generations)

MY EXPERIENCES AT KGP

Starting from KGP station

Reaching IIT for a week of orientation

Rising early in the morning sleeping jaldi at night

Thinking and planning to start a new life

Roaming about the campus and knowing IIT

Feeling proud of myself that I cleared JEE

23’rd July, our class begin

Getting disappointed finding no girl good looking

Meeting talents coming from whole country

I realized that acads are not the boundary

Every evening I used to go out to play

Thinking to become an Inter-IIT player someday

Very soon after that our mid-sem began

I realized that I’ll have to study again

Mid-sem ne mujhe badi problem mein dala

Fir bhi maine khud ko kisi tarah sambhala

Then ILLU season comes and our schedules change

3 or 4 in the night became a kids’ game

ILLU mein to humne sabki watt lagai hai

I came to know the meaning of “RK ka tempo high hai”

All big dreams seemed to be in vain

Getting a 9 became my only aim

Luck was with me and everything went fine

Thanks to God, I got a nine

January was like a great festive season

Celebrating always with or without reason

Dancing on the tunes of DJ and Kailasa

But my favorite event was workshop on salsa

Working all night to prepare our bot

Events of Kshitij were really hot

But with all masti all load, all fun and pain

Don’t forget, what’s our ultimate aim

We miss our home our mom and dad

Don’t do anything that makes them sad

I’d like to spread one message through

Your parents have got great trust on you

They have sent you here to learn something

Please don’t indulge in smoking and drinking.

KGP IN RETROSPECT

“The pain of parting, yet the thrill of a new beginning,

A dream accomplished, yet millions more to accomplish…”

These were the thoughts as I entered the gates of one of the best technical institutes of the

country as a young, immature 17year old. The view of the old Insti Building lit by the August

moon, the Main Insti Building which has shaped some of the finest personalities of India, the

2.2 Km Scholars Avenue adorned by the various Halls of Residence on both sides were

enough to make me proud of my accomplishment and look forward to my next four years

stay at IIT Kharagpur.

On my first day, as I walked through the hallowed corridors of S.N.Hall with hesitant

steps, lost among a myriad of girls from different parts of the country, I met my batchmates

and seniors, who would become my ‘friend, philosopher and guide’ within a few days. The

‘Unconventional’ welcome we received from our seniors, working day and night wiring

diyas, being a part of each and every dramatics event-be it Hindi, English, Bengali or

Choreography, campaigning for friends during elections were some of the highlights of my

first year at S.N. Hall. Through all these, I met new people, made new friends, learnt new

things and imbibed new qualities.

Come second year, and suddenly I found myself addressed as a senior. SF, Inter IIT,

Inter Halls, Elections, EE Department-priorities were redefined and timetables set haywire.

The day I joined the SF Team as a member in my second year was one of the most defining

moments of my stay here. 6 months of endless meetings, niteouts, treats, the calling queues

at RK and KAT booths, the never ending calling lists and trips to different parts of the

country…and then 4 days of revelry, of stars from home and abroad, of people from all over

India, of a plethora of events and of a fest which Kgp has celebrated since its inception.

Inter-IIT was another wonderful experience-going to Mumbai, playing for my insti and

meeting new people. Although we couldn’t manage a podium finish, the memories of this

extravaganza will stay with me throughout my life.

As with almost everybody in KGP, my stay here was shaped by my hall. Living away

from home for the first time in my life, S.N.Hall became my second home. Surrounded by

friends 24X7, discovering a new family in my wingies, being involved in a host of events

throughout the year-my hall has given me some of the best moments of my life, taught me

to believe in myself and explore new paths, and unravelled hitherto unknown talent in

dramatics (never mind the language), fine (and allied) arts, basketball, tennis, diya wiring,

rangoli….the list would never end. The euphoria of Inter Hall wins and the pain of losing, the

tempo shouts, wiring diyas for an entire month and then the spectacular sight of thousands

of diyas lighting up simultaneously, living in the suffocating common room for 7 days

straight and watching the 400 square feet rangoli come to life….sweet memories unique to

Kgp. The twin bronze in Illu and Rangoli in my final year is one of my best memories of Kgp.

KGP has given me my best friend, awesome wingies , the coolest Bhaiyya and

amazing depmates. This place is about a friend who would go all out to see me happy. KGP

is about Akriti, Sneha, Sheetal and Heena….the best friends ever. Chandipur, Kolkata,

VIBGYOR, 70s heroines, treats at TP, PD, Park, LS, Birthday Parties at Hall and VGSOM, JCB,

Billoos, Sahara, Cheddis, Tikka, the summer months and the placement season…memories

that will stay with us and make us smile forever. KGP is about cooking food in the room, 5

people eating from 1 plate, the entire wing living in one room, spending an entire afternoon

searching for clothes to wear for a 3 hour treat, the entire wing sharing everything from

clothes, accessories and cycles to buckets and brooms, gtalking each other although we live

right next to each other, religiously visiting the Xerox shop before every exam, rakhi,

friendship day n valentines day, boyfriends, niteouts for no reason, dance parties, movies,

photo-sessions, 2.2, BigB and lately CCD.

Kgp is also about Niraj, DebC, Rathi, Akriti, Manish, Romil, Avinash, Bhaiyya, Vikas,

Mishra, Raghav, Dadhich, Somani, Sheva, Aritra, Sneha, Mona, Krit and Rajat. Blessed by

mummy, papa and bhaiyya, this small but happy ‘close-knitted Instru parivar’ is one of the

most amazing branches in the insti-we set our own rules, and decided our own deadlines.

Not even the fact that we belonged to the most dreaded department in the insti could make

us attend classes or submit assignments or study even one day before an exam. Shankarpur,

Birthday Treats, Hall Days….we enjoyed all these and many more during our four-year stay

here.

KGP is also about the seniors that were and the juniors that are. I have been lucky to

have some great seniors and equally amazing juniors, with whom I have lived, worked and

learnt.

Today, as my four year stay at Kgp nears an end, I realise that I have been lucky to

come and stay here, and experience these four years. There have been both happy and sad

moments, easy-going and difficult times, but through all these episodes we stood together

and leaned on each other, providing solace and support. My ‘four year transform’ has

equipped me to face the future, come what may, given me friends and memories to keep

me going throughout my life. As I leave Kgp to explore new fields, I will miss my wingies,

friends, juniors, dep mates, SF, Inter IIT, Illu, Rangoli, GC but above all, I will miss KGP…the

place which has given me all these and much more…..

What we learnt?

Away from our homes, We came with some goals.

Now, In the flashback of time

I look back and see The transformation of me

In the ups and the downs

Of our life What we cherished

Were The friends and the laughter and

The memories thereafter

In the silence of the day And loneliness of the night

What we thought Were

Of the rays of dawn that can Prevent us from feeling down

At some lonely times and

No work at times What we missed

Was The company of our loved ones

Parents, Elders and the Young Ones

In this run of life To prove our points

What we lost Was

Someone unknown that Could have been known

What we learnt?

Is it done?
