MISSION PERFECTION :

A Journey of Self DiscoveryTake a limitaon and turn it into an opportunity. Take an opportunity and turn it into an

adventure by dreaming big.

These inspiraonal words by Jo Franz paint a beauful colour-stroked rainbow that one witnesses aer the

long hours of silent rain. Here the rainbow is symbolic of t he hope, hope easily being the best of all things has

encouraged all the inquisive minds to toil hard to reach and achieve their ulmate dreams. Aer the long,

ring days and nights of hard work, the eorts of the students li ve the sweet essence of success and nally are

paid o well for their sincerity by geng admissions in one of the best educaonal instuons of the country.

It is quite obvious that the students and their guardians have very high expectaons from the college, when it

comes to the overall development of the fresh out of school, young, brilliant minds.

Certainly, NSIT acknowledges this anxiety and strives to live up to the expectaons of the students and their

parents. The rich and the commendable history of NSIT speak louder than the words and it imparts a great

sense of pride to each and everyone associated with this instuon.

Apart from the excellent academic front, the construcve environment at college ensures that each and every

student gets the best opportunies to tread the path of success in the long run. NSIT works out the brilliance

of diamond in the students who are undoubtedly the brightest minds in the country. Technical or even non-

technical elds, the college has always promoted the students to experiment and bring out the best of their

innovave minds.

Leave alone the academic front, the college is bounful of people with varied interests and thus gives each one

a chance to explore and elicit their buried abilies ensuring an overall progress and personality enhancement.

Many cultural, technical and sports related sociees are acve in the college under the proper guidance of

senior students and faculty giving the students a wide range of choices to pursue and excel in their eld of

interest as well as hobbies and ensure proper professional training of the members as and when required.

To ensure that each and every student gets ample opportunies to be thoroughly acve in the college various

fests are organized me to me where parcipaon of all forms of talent is profoundly applauded. In the l ong

period of four years get opmum me to pursue their various interests apart from the academic front.

The placement history of NSIT needs no words to prove its excellency and the good placements denitely

serve as the perfect delicious icing on the cake nessed out in the golden four years. Every regular student

who had entered the college with high hopes comes out as a mature, ecient and well groomed graduate who

just not holds a graduaon degree but all the principles and virtues to succeed in the journey called life.

INTERVIEWWITHAVNI JAIN

Can you brief us about the placement procedure at Goldman Sachs, and

also if you could elaborate your road to success there.

What according to you is the best time to start preparing for placements?

What prole have you been offered at Goldman Sachs?

What do you think, gave you an edge over others? We would be obliged if

you could elaborate upon it.

Goldman Sachs had 4 rounds in all. The rst round was the resume short lisng following which they had

various round of interviews. The rst interview round had quesons based on the resume itself and I was also

asked to assess a problem statement and suggest a possible soluon for it. The problem was based upon data

analysis and I was judged on the approach I had taken to suggest a possible way of encountering the same.

Some simple programming quesons were also asked and a lile on nance. The 2nd round basically tested

me on quantave and logical ability and problem analysis. To assess me on these parameters, I was asked

puzzles and mathemacal quizzes which most people would be able to solve i f they are preparing for CAT/

GMAT or for aptude based quesons for placements. The 3rd and nal round was the HR round wherein one

has to be very careful about not saying something that one has not prepared an answer for.

I personally believe if you have been regular with your academics in your 2nd and 3rd year then you need

only about 15 days prior to the start of the placement season to prepare yourselves well and brush things up.

If that is not the case then you need to work hard in the summer vacaons.

I will be working as a Data Analyst in Goldman Sachs.

I think that, that parcul ar day they were looking for somebody who could use basic raonal and logical

thinking to solve data analysis problems. And to be able to do those quesons, the only requirement is

to possess a raonal thinking ability. Also if you are a hardworking student who is willing to learn that

automacally shows while you are talking. So, I think if you have a mix of all the above things in the right

quanty then you could be at Goldman Sachs too.

You had also received a PPO from Texas Instruments. How was your

experience being an intern there?

Tell us about the projects you worked upon? How did they help you in your

learning process?

How would you describe your four years stay at NSIT? Any particular

professor or senior youd like to mention here?

The internship aer my 3rd year in TI was a great learning experience. It was the 2nd me I was interning with

TI so I did have a basic idea of my prole but it became clearer in the 2 months I spent at Bangalore. I think

it was a great opportunity to assess myself before I would have worked there as a full me employee. Also

it gave me a taste of how things work in a corporate environment which I think i s prey important to know

before joining any company.

I worked on the automaon of spice modeling of op-amps. During the i nternship I had to read a lot about

basic electronics and op-amps in specic. So the internship, in a way, prepared me for the placements. One

thing that I realized there was that when one is working in an ocial environment he/she learns things that

are applicable to systems in the real world, that one can never learn whil e being in a college. So it gives you

an edge over others in your placements as well. Also, as in the end you want a PPO, so you work twice as hard

as before and with a disciplined manner, which helps you further.

My four years in NSIT have been very happening, fullling and busy. In these four years, one very important

lesson that I have learnt is that you have to really put in your hard work and eort to expect anything from

somebody (here NSIT). I have made friends for life, grown as a person and learnt lessons about life. When you

are in this place you curse it for umpteen things, but you actually realize its true worth only when its your

me to say goodbye. So enjoy your four years and make the most of it, not only when it comes to mas but

also when it comes to learning things, and yes you do learn stu in this college.

CAMPUS EVENTS

INNOVISION

The 2-day Annual Technical-Cum-Managerial Fest INNOVISION13 had an incredible beginning on 21st of

March, turning NSIT into a warzone for students, all compeng in a plethora of events, for the glory of deep

taccal, engineering brains and their locomove robots.

In the early hours of day one, the Defense Auto Expo by the Indian Army had the eyes of the audience in

the Moksha ground, where the queries of the bright yet inquisive minds of students were cleared by the

men in uniform.

RoboWars was one of the most awaited events of the fest. A huge swarm of students had assembled to

not only witness the genius of the intellectual parcipants, but also the strength and endurance of their

robots.

Innovison witnessed a plethora of robo events like the Carnage Wars, Black Pearl and the Line follower.

Robots traversed challenging tracks in the shortest possible me frames. Line follower was an automated

robot event, the arcial intelligence quoent of the line followers as well as the accuracy of the photo

detectors were the things to l ook out for. Each event had plunged in huge spectators, who applauded thegenius of the students and appreciated the level of compeon.

The most spectacular and memorable event of Innovision13 was the Laser Show. The colors and the

dynamism invigorated each soul in that energec stream of merry making, while the sky dazzled with

colorful lights and the dance oor vibrated with Bollywood beats.

The two days of conviviality and fun not only bestowed the students with a plaorm to showcase

their talent, but also embraced them with the most memorable moments ever spent in the college.

Innovision13 concluded on a high note wherein the students showcased their creave and high technical

gadgets combined with innovave technology.

MOKSHA


7/15

On March 22, the unforgeable Movie of Moksha

13 kick started. This fests theme 100 Years of

Bollywood - was completely jused with what

followed in the fest.

Day one saw the crowd gathering in the Main

Auditorium for the Inaugural Ceremony where the

Gupta Brothers and Shubh Maharaj ji mesmerized

the audience with their capvang Hindustani

classical music performances.

Aer this came the Kavi Sammelan. People with

vivid imaginaons produced glimpses of their

genius with mastered works of poetry and sare.

The jam packed auditorium was ecstac when the

Shri Santosh Anands greatest work, Ek pyaar ka

Nagma, was performed.

As the sun went down, people moved towards the

Moksha ground for NSITs rock night, Avalanche.

The shaking of the earth could be felt as metal

bands played guitars and drums - for some, it

was an ear-spling enigma; for the others, the

adrenaline rush was a high in i tself.

The second days rst event - the Street Play

saw teams from dierent colleges bring the

administraon block to life. I n the evening, Oorja

saw scinllang performances in the Western

Dance Compeon. The team from PEC stole the

show with their vivacious dancers. The day came to

a close with NSITs Fashion Parade, Rogue, that was

a raging success with all the hoong and uctuang

heartbeats as its witness.

The ancipaon of the most awaited event of the

fest SUNBURN exceeded expectaons on the

nal day.

In a plethora of music and an abundance of swag,the event started bang on with everyone trying

to match the DJs beats. DJ Anish Sood proved his

worth by mesmerizing one and all in a sea of music

and sky of reworks.

At the risk of being a lile dramac, its safe to say

that Moksha 13 started with a large boom and

ended with an even bigger bang.

COLLOQUIUM

As the great author Noam Chomsky quotes, The smart way to keep people passive and obedient

is to strictly l imit the spectrum of acceptable opinion, but allow very lively debate within that

spectrum.

Debang is an art of the wise.

The Debang Society of NSIT, popularly known as Debsoc, organised the rst edion of its annual

debang fesval, Colloquium from 29th to 31st of March. The fest that kickstarted with a Panel

Disccusion, consisng of panelists in the likes of Mr. Anubroto Roy, Ms. Ira Trivedi, Mr. Ashwin

Sanghi and Dr. Mallika Sarabhai, enlightened the audience with their valuable opinions, and true

to the topic, these had a vision quite dierent as that of the general societys percepon.

Following was the Literary Quiz, a set of mind boggling quesons that le people wracking their

brains. At the comic workshop, that was to follow, Mr Akshay Dhar and Mr Pran came up on

stage, the students being fortunate enough to be able to interact with the heroes of Indian comic

industry.

Amidst all the acvies, the highlight of Colloquium was NSIT MUN. With the aim of taking one

more step towards naonal integrity and internaonal peace and harmony, the second edion of

NSIT MUN took place in the premises of NSIT. All the commiees- the Human Rights Commission,

the Security Council, the General Assembly, and the Shanghai Cooperaon Organizaon had ery

and heated discussions on the respecve agendas, one of them being for example on, Israeli

pracces and its eects on the human rights of the Palesnian people in occupied Palesnian

territory.

The Joint Parliamentary Commiee (JPC) that went on parallel with MUN, was a newly introduced

and well appreciated eort at the college level. The debaters churned their mouths out on the

topic Liming the benets of Direct Cash Transfer Scheme to the holders of Aadhar (UID) cards.

Amongst the other highlights of the fest were Crack the Case, News hour Debate and Judgement

Day all of them concluding the fest on a high note.

With the end of a three day debate-lled fest, colloquium proved to be a huge success, credits to

the DEBSOC Team, which worked hard and pulled o such an amazing fest.

QUIZ FEST

Quizzing has always been a game of the smart; only the

ones with more of that grey maer in their brains can live

up to the thrusts of quizzing.

The Quiz Club of NSIT organised the h edion of its

annual NSIT QUIZ FEST from 15th to 17th March.

NSIT is known for its extra talent in quizzi ng and this makes

the fest a very important event in the quizzing circuit. Every

year, the fest is known to witness the parcipaon from

colleges all over the city. This year, the Quiz Club did a

commendable job preparing a plethora of head scratching

quesons triggering the minds of quizzers throughout the

fest. A variety of quizzes were organised, including the all

awaited Bollywood, Sci-Tech and Sports Quiz. Amongst the

minor ones; the MELA quiz, and the open quiz aracted

huge numbers.

The team from IIT Delhi, who conquered this baleeld of

quizzes, emerged as winners.

The agenda of the Congress was not only to have an ecient networking structure, but also to strengthen

the collaboraon plaorm and improve industrial relaons which may open up diverse opportunies.

The conference saw the parcipaon of more than 100 students from around 25 branches across the

whole Delhi Secon. Nominaons were taken from all the branches for the Secon commiee and the

concept of formaon of three dierent Groups was introduced.

Each student came up with nominaons of students who will be responsible for networking acvies,

managing collaboraon plaorm and improving industrial relaons for the corresponding group. The

conference nally came to an end with a highly opmisc note, with a new hope for a beer coordinaon

among the branches and the new relaons which are now set up between the various students aer the

healthy interacon of two days.

Organising the rst ever Delhi Student Congress was an unforgeable experience for the IEEE NSIT

Execomm, wherein they got several opportunies to hone their managerial skills and at the same me the

congress enabled student members to build a healthy network with the people of Delhi Secon.

VIRASAT

The Society for the Promoon of Indian Classical Music And Culture Amongst Youth (SPIC MACAY), NSIT

chapter organised VIRASAT13 from 8th April- 21st April. The various events organized under SPIC MACAY

included LEC-DEMS(Lecture Demonstraons), Workshops, Concerts, Folk Art and Cras, Talks, Cinema

Classics, Yoga-Holisc Camps, Convenons, and Holisc Food And Heritage Walks. A whole new atmosphere

lled with rich Indian cultural heritage was created. This year a variety of events took place with eminent

personalies vising the campus.

Padma Shri N.Ranjam enthralled the audience with her sweet notes of Violin while workshops on Kathak

and paper Mache provided an opportunity for students to learn and get cl oser to their tradion. When

the auditorium was echoing with songs like Dumadum mast kalandar, kesariya balam and nimbuda

nimbuda, one could have easily got up and danced to their tunes, such was the magic of the Rajasthanic

folk music. An exemplary performance by a vocalist, Smt. Sunanda Sharma also set a tune for a melodious

evening in NSIT. The screening of movies like Bicycle Thieves was just an icing on the cake. But the most

memorable experience was the Heritage Walk to Purana Quila.

For two weeks, the college was surrounded by an ocean of surs and taals, the legacy of the ragas spreading

to the next generaon. The unadulterated aura of our cultural heritage, its vastness and beauty lived up

to the high expectaons of the listeners. It provided movaon to all those who has always wanted to

learn the classics in any form they wanted to. The condence and the excellence with which the arsts

performed were worth to vouch for. The true India was presented in its varied colours. The memories of

this experience would connue to live on forever.

For once in life the visitors saw a monument coming to life an explaining its varied and rich history.

TECHELON

Addicve gaming, brain cking quizzes, cerebral rush inducing challenges, all at one spot.

Techelon13, by CSI - NSIT presented a plethora of events like the IT quiz, math wrath, treasure

hunt, blog wring and sound eding. Techelon featured addional events like Digital Fortress,

workshops on Introducon to Compeve Programming, and another by Google developer group

members on Android Dev. The gamut of acvies deed the brightest of minds and put their

intellect and adept skills to test and touch new horizons of ingenuity and innovaon.

While the students worked their way out of the IT quesons, the MathWrath which combined

the mathemacal and programming skills provoked everyones mind. The Blogizmo and PicMorph

judged the creave skills and Digital Fortress and treasure hunt were a real test of wits.

The rush of adrenaline and goose bumps during the challenges made them even more fun. The

week long esta encompassing several astounding online and oine events emerged as a viral hit

amongst the crowd. Aracve prizes likes pendrives and headphones were given to the winners of

various events.

ENGINNERING

The ECE Department is also equipped with t he Centre for Electronics Design Technology(CEDT), aperfect place for students who wish to learn and explore the world of Embedded Systems under the

supervision of Prof DV Gadre. The students of the ECE Department generally get an access to this lab

during the winter training session. This Centre also launched an evaluaon kit based on Stellaris Cortex-M3

embedded processor plaorm from Texas Instruments in July 2012 with contribuons from Rohit Dureja

and Shanjit Singh Jajmann, both nal year students who were persistently mentored by Professor DV Gadre

through the process.

Stellaris Guru is an entry-level evaluaon kit for ARM Cortex-M3 embedded processor. It is intended as an

educaonal tool in engineering instuons and is based on LM3S608 microcontroller unit, which i ncludes

a 32-bit ARM Cortex-M3 processor and a variety of popular user interfaces and peripherals. A lab manual,

Geng started with Stellaris ARM Cortex-M Embedded Processors was also published recently, authored

by Professor DV Gadre, Rohit Dureja and Shanjit Singh Jajmann.

Apart from Embedded Systems, students have been working upon Wireless Communicaon, Microwave

COMPUTER ENGINEERING/

INFORMATION TECHNOLOGY


Be it any discipline of acvies business, educaon, government, to name a few the presence andinuence of the computer and informaon technology sector on their funconing cannot be undermined

by a long shot. So it is always pleasant to come across stories when a prodigy takes up his or her role in the

aforemenoned industries.

NSIT boasts of providing a culture that helps reducing the hurdles encountered and providesenough opportunies for students to come forth and rise. Nonetheless, it is never an easy path. Many know

about the same; few start taking up these opportunies; sll fewer go through with them completely.

Recently, Arnab Kumar, a third year computer science student enrolled in NSITs undergraduate programme

had been working in an area of applied Machine Learning research (more commonly known as Social

Network Analysis (SNA) ) under the guidance of Mrs Sushama Nagpal, Asst. Professor, NSIT.

- Their primary eld of research was the Tie Strength Problem applied on the social networking site

Facebook, with one of their research papers being accepted at the Internaonal Conference IC3 2012 wit h

further publicaon by Springer in the CCIS Series (Communicaons in Computer and Informaon Science

Series) and indexing in DPLB, ISI and Scopus.

To be able to appreciate and give a beer perspecve about the work pursued by Arnab, it is easy to

observe that recent trends in the online behaviour of people, and the surge for personalizaon of the web

has driven a lot of aenon towards working on the problem of Tie Strength, using data available on Social

networking sites such as Facebook, Twier, LinkedIn, to name a few.

Geng into some technical details, understanding Tie Strength can improve social media design elements,

including privacy controls, message roung and informaon priorizaon in databases.

As a result, Computer Science Researchers all over the world have been using Machine Learning

Techniques, Graph Theory along with some other stascal techniques to analyse this problem, which theybelieve can revoluonize the way we see the internet.

This was followed by his work as a research fellow at IIIT-Delhi under the mentorship of Dr. Somitra Kumar

Sanadhya and of Dr. Donghoon Chang. He is working on preimage aacks on Hash funcons, with the

best cryptographic system available right now- SHA 3 in mind. This research work fetched him the tle of

Best Research Poster Paper Award at the Microso Research Showcase at IIIT-Delhi. Moreover, two of his

research papers on cryptanalysis of Hash func ons are now under review by reputed conferences.

For those unfamiliar with the discipline of cryptanalysis and its recent developments, cryptanalysis

involves work with algorithms and techniques used to breach cr yptographic security systems and gain

access to the contents of encrypted messages. A cryptographic hash algorithm is a widely-used tool

that creates a ngerprint, or a message digest of a le, message or block of data that can be used for

digital signatures, message authencaon codes, and many other security applicaons in the informaon

infrastructure.

Arnab, along with Dr. Somitra Kumar Sanadhya and Dr. Donghoon Chang have been working on preimage

aacks on such hash func ons, and have partly been successful in their endeavour.

INTRUMENTATION

AND

CONTROL ENGINEERING

Instrumentaon, in itself, has a very broad spectrum for research and possesses a unique interdisciplinary

character. So it comes across as no surprise that its presence in Netaji Subhas Instute of Technology has

been proliferated by numerous research undertakings though the years.

Since the number of these undertakings/ projects is a big one, for the moment, it will suce to know their

basics and main requirements.

Two of the most popular techniques that are used in virtually all instrumentaon projects are those

involving arcial neural network and fuzzy logic. Even GA (Genec Algorithm) and PSO (Parcle Swam

Opmizaon), which are mainly used for opmizaon of various parameters, are of vital importance. In

hardware, one has many avenues to work on, including FPGA (eld-programmable gate array).

Extremely important are simulaon sowares such as MATLAB and LABVIEW that are used for analysis

and simulaons of almost every kind of program one can nd. They are used to monitor important

industrial variables such as Pressure, Temperature, Level & Flow.

All in all, the system that has to be controlled or linearized can be anything, including everything from a

DC motor to a Thermistor, but the basic techniques (ANN & Fuzzy) required to approach the problems

remain more or less the same.

A Virtual Instrumentaon Approach to Neural Network-Based Thermistor Linearizaon on Field

Programmable Gate Array

Ifthenameitselfsoundssosophiscatedandcomplex,imaginewhattheactualpaperwillhavetosay.

OnJanuary31earlierthisyear,thisarcle,co-authoredbyKPSRana,NMira,NPramanik,PDwivediand

P.Mahajanwaspublishedonlinefortherstme.

Stang the absurdly obvious, temperature measurement is an i mportant pre-requisite in many industrial

applicaons, irrespecve of the method employed. All engineering components have some form ofdependence on temperature and heat transfer.

Consequently, its only obvious that people will look for newer opons to facili tate the same with

increasing eciency and decreasing cost.

Taking one such method into perspecve, a Thermistor is used to a great extent for this purpose in

many industrial applicaons for its cost eecveness, small size and good sensivity. Because of its non-

linearity, eecve usage of a Thermistor requires some mechanism for linearizaon.

This paper presents a simple step-by-step, praccally implementable arcial neural network (ANN)-

based linearizaon method for Thermistor characterisc using a two-layer neural network having two

neurons in each layer. The trained feed-forward neural network is implemented on a eld programmable

gate array (FPGA) on the NI-PXI plaorm for real-me measurement.

Even apart from this paper, ICE professors Rana and Vineet Kumar are working on hardware based

instrumentaon and control applicaons. They have various hardwares from Naonal Instruments like

DAQ (Data Acquision) cards, FPGAs, PXI computers and sowares like LABVIEW that provide suitable

plaorm for studies in our eld.

MANUFACTURING PROCESSES

AND AUTOMATION ENGINEERING

Dr SK Jha, a senior faculty with the department

of Manufacturing Processes and Automaon

Engineering (MPAE) has done his PhD in Grinding

technology from Naonal Technical Instute, Kharkiv

Polytechnic Instute, Ukraine (then USSR) during his

tenure there from 1982-93.

Since quite some me, the area of his research

has become one with a high priority i n the

manufacturing industry, and its importanceconnues to grow even today. And thats not just

because it caters to a vital step in any manufacturing

line today, which of course it does, but also because

not a lot of research has been done i n the eld

previously.

Electro-Chemical Discharge Machining is anotherarea of research which is being pursued by Dr.

Sanjay Chak, Associate Professor, Department

of MPAE. ECDM combines the characteriscs of

Electro-Chemical Machining and Electro-Discharge

Machining and has shown potenal to machine

electrically non-conducve materials such as

ceramics, quartz, glass etc.

Narrowing down more to his actual area of

work and being more specic, Dr Jha has done

extensive research on grinding with super abrasive

materials, namely Arcial Diamonds. His work on

metal bonded diamond grinding wheels has been

recognised widely.

One of the main reasons as to why research in

the eld of grinding is dicult is that in case of

grinding wheels, its more of a game of probabilityand stascs rather than exact mathemacal

predicons.

Simply put, since the grinding wheels can be

considered to be made up of a number of single

point cung tools, one cannot predict t he exact

nature of the outcome of the usage of grinding

wheels.

Despite successful applicaon of ECDM, researchers

sll nd dicules in machining ceramics specially

Silicon Carbide. Dr. Chaks paper explored Machining

of SiC by ECDM process using dierent electrode

conguraon under the eect of pulsed DC. He

also conducted research on drilling of Aluminium

Oxide using Pulsed DC supply with a rotary abrasive

electrode using ECDM Process.

Dr. Chak also has an experse in Rapid Prototyping -

group of techniques used to quickly fabricate a scale

model of a physical part or assembly using three-

dimensional computer aided design (CAD) data.



13/15

Whilst the facets of Netaji Subhas Instute of Technology surrounding the streams of mechanical,

instrumentaon and computer science have received many laurels and have been recognised widely,

perhaps the stream of Bio-Technology hasnt been commemorated to an equal standard.

That opinion will surely be chall enged when recent developments in the eld of bio-technology come into

the mainstream.

In August, a research on anmicrobials, commonly known as anbiocs, was undertaken by a group of

enthusiasc students from NSIT, with the focus of the research on Acnomycetes.

Geng into some technicalies, this refers to a group of micro-organisms that are gram posive. Theyare generally anaerobic bacteria which grow in a lamentous or branching paern. Many species of

Acnomycetes have been known to exist in soil and are harmless to animals and higher plants. Whilst some

are important pathogens, many others are benecial sources of anbiocs. Their possession of properes

similar to those of fungi makes them an important area of research.

The researchers are trying to extract an-bacterial and an-fungal agents that would help in ghng a

broad range of bacterial and fungal infecons. Use of intricate and modern machines such as laminar

air ow cabinet (which provides a streamline and contaminaon ow) and spectrophotometer (which

measures the amount of light of a specied wavelength passing through a medium) has added a new gear

in the research process.

With 7-8 months of successful research in their backpacks, t he researchers are posive that their big

breakthrough is right around the corner.

ENGINEERINGby Prateek Jha, ICE-Batch 2012

The idea of nkering and building stus always aracted me. Aer the compleon of a year at college, I found

this lile space inside NSIT where I could fulll my desire. It was the CEDT lab run by D.V. Gadre sir. I presented

him a micro-controller based line-follower/maze solver robot made by me as a cercate of my ability and

keenness to work in the lab. He took me in. Generally, he asks students to prove their worth by building a

power-supply. Aer my incubaon I spent most of the me in the lab. I just loved it out there.

Fast-forward to fourth year. I took up the challenge of building a CNC machine as my B.Tech Project. D.V.Gadre

sir and S.K. Jha sir were my mentors.

The project was suggested by D.V.Gadre sir. All I knew then was that I had to build a machine that is capable of

wring on spherical surfaces. Lile did I know then of the amount of learning I was supposed to gain and that

this project would be like a one semester crash-course of a four year engineering degree.

Another thing that is to be strictly kept in mind when working under D.V.Gadre sir is that no part should

sustain itself on the concept of jugaad. The aspect in which we all Indians are prey good. I got a good

lecture when I presented him a jugaad based development. Hence the machine should stand sturdy and

strong, always which jugaad doesnt promise.

Now, CNC stands for Computer Numeric Control. In the present mes, most of the high quality industrial

manufacturing is performed using CNC machines. They are used for cung, milling, welding, dril ling, lathe,

3D prinng, picking and soldering complex Printed Circuit Boards and much much more. They have become

the basic foundaon of our modern industrial age. The gure below should give an idea of CNC procedure.

Any design can almost accurately be broken down

in arcs and lines. So all that the G-code les (when

related to my parcular project) contains is where

to draw the lines and arcs so that in the end we have

a copy design in tangible form. Developing a CNC

machine requires knowledge of almost all the elds of

engineering. I implemented Bresenhams straight line

algorithm and circle algorithm on Arduino. Ironically,

this was the very semester in which I could nally

cleared my back-paper of Computer Graphics too.Whew!

And the nal challenge was to bring al l these together into one piece. And this aspect is what we call

Engineering. I call my machine The Chakradhar.

NSIT has umpteen number of sociees, ranging from technical to cultural. But

then there are those which cannot be classied into categories, and are an integral part

of the college. One such society is Crosslinks. Crosslinks is the ocial media management

society of NSIT, which works for promong the brand name of NSIT in and around Delhi.

Each academic year, Crosslinks organizes the orientaon of various sociees for the

freshers. This is followed by The Freshers Week wherein the newbies get to understand

the funconing of various clubs and sociees and can select the ones they want to be a

part of. Crosslinks brings forth various student iniaves, accomplishments and acvies

through frequent newsleers and the ocial college magazine. It also provides NSITians

with the plaorm to parcipate in talk shows conducted by NDTV and Doordarshan.

Over the years, Crosslinks has emerged as a student forum which provides the studentswith comprehensive informaon. At the same me, it has endeavoured to create a niche

for NSIT in the educaonal arena.
