NUrap : Development of Proportional-Integral-Derivative controller on arm cortex M4 processor and integration of  webserver for  controlling purpose

We talked about the NU Research Assistantship Programme (NUrap) in our last blog, it is designed to engage the students of NU more deeply in the research life of the University. The programme therefore provides opportunities to work with the faculty to carry out innovative research and to vigorously pursue the applications that flow from it.

There are a series of project under this programme and the second one is “Development of Proportional-Integral-Derivative controller on arm cortex M4 processor and integration of  webserver for  controlling purpose” undertaken by Samit Singh, ­Vishal Mohankumar and S R Rahul and their Mentor is Prof. Jetendra Joshi. So here is how the students feel about NUrap in their own words.

Proportional ­Integral ­Derivative (PID) controllers are used in most automatic process control applications in industry today to regulate flow, temperature, pressure, level, and many other industrial process variables. PID controllers are the workhorse of modern process control systems, as they automate regulation tasks that otherwise would have to be done manually.

So, we developed a PID controller on arm cortex M4 processor enabling the IoT for monitoring of controlled variable, reference and error signal and for the remotely industrial control purposes via web or application user interface, which will reduce the overhead on C&I engineers.

Web services incorporated are: Monitoring and Controlling of process variable remotely and we can also export the stored data in various formats (like csv, json, xml). We also provide learning and experimental tuning of Proportional, Integral and Derivative gain. The process control system (and operators) of your plant try to maintain the essential process variables such as quality variables, temperatures and pressures at target. The targets are chosen such that the limits, in spite of the variations in the process variables, are not exceeded. Subsequently, the targets can be chosen at more profitable values.

“It was great experience working, struggling and progressing with arm cortex m4 processor with my mentor Prof. Jetendra Joshi and developing full end product for stabilizing the industrial process variable”­ Samit Singh (B.Tech ECE 2013­17)

“I learned a lot about IOT and Cloud in this project. It was fascinating to work on cloud analytics and how large amount of data could be processed in the cloud. This field was new to me and I had a great experience working with my mentor Prof. Jetendra Joshi who guided and helped me throughout the project. There were lot of learnings and I am looking forward to work on more projects from this field.”­Vishal Mohankumar (B.Tech CSE 2014­18).

“I learned embedded system working on Arduino and raspberry pi and interfaced various sensors.”­S R Rahul(B.Tech ECE 2014­18)

NU Research Assistantship Programme (NUrap)

The NU Research Assistantship Programme (NUrap) is designed to engage the students of NU more deeply in the research life of the University. The programme therefore provides opportunities to work with the faculty to carry out innovative research and to vigorously pursue the applications that flow from it. The students will get an opportunity to work very closely with and be mentored by faculty researchers to enhance their skills in areas of their interest. The aim is to develop innovative solutions to the most daunting challenges by engaging in frontline research at the frontiers of modern technology and this initiative is indeed a commendable one.

There are a series of project under this programme and the first one is “An Improved Remote User Authentication Scheme for Privacy-Preserving for TMIS” undertaken by Aakansha Kapoor and Siddhant Bhattacharya and their Mentor is Prof. Trupil Limbasiya. So here is how the students feel about NUrap in their own words.

We feel security is an important aspect of any system or for any person hence efficient models should be implemented in order to make things and information/data more secure.
Generally, a secure system has 3 necessary requirements such that authentication, privacy and integrity all of these help make a secure environment in which the data can be saved.
Our project deals with Telecare Medicine Information Systems (TMIS), as here we are dealing with a person’s medical data, we need to take care of the authentication protocols to access the data as well as maintain the privacy desired by the person as well as maintain the integrity of the data.
But the most important aspect of this is authentication of the person using the service hence our prime focous has been authentication of the user. Also in order to make the authentication process flexible we are inplementing remote user authentication to overcome some weaknesses.
“It was a completely new experience for me as I had never studied any subject from this domain but I did learn a couple of things which has helped me to select my electives for my next semester and as a matter of fact I have developed a liking for this domain and I must say my mentor Trupil Limbasiya has helped me for the same. I am looking forward to studying further and working in this field”- Aakanksha Kapoor(B.Tech CSE 2013-17).
“I, being a student of information security, was quite influenced by this field and I wanted to work on such core research projects, I still recall that after taking my admission in this university I was asked that why did I join this university? My answer was I wanted to do research and after 3 years, here I am, totally engrossed in doing what I love, research. It has been really a great experience for me with my mentor Trupil Limbasiya who has helped me understand more advance concepts of this domin, I want to continue my work in this field.”-Siddhant Bhattacharya(B.Tech CSE 2013-17).



Internship Diaries

Chapter # 2

by Rishabh Sharma, B.Tech CSE-2016


I joined ZiffyHomes as a Web Development intern. Working in a startup is very exciting and challenging . In last few months, I have learnt a lot about planning, meeting deadlines and how to have fun while working.  In the first few weeks itself I was given the work of creating the website for the company. While doing so I learnt a lot about how to structure your codes. I worked on different frameworks and I didn’t even know about half of them before my internship started. Working on a live project or website on which the future of the company depends is a completely different experience. I am about to finish my IP here and I can see the changes it brought to my skills and personality.

I am currently working on the last module of the latest version of the site and in a few weeks, we will be launching it.

I am really glad with this experience.

Chapter # 1 

by Jhalak Sharma, B.Tech ECE-2016

Industrial Practice Organization: Space Application center (ISRO).


For my 6-month Industrial Practice, I had the opportunity to work at the Space Application Centre (ISRO), Ahmedabad. Without a second thought, I accepted, as ISRO is a prestigious institution and it also happens to be located in my hometown. What else I can ask for?

About SAC: Space Applications Centre (SAC) is one of the major centers of the Indian Space Research Organization (ISRO). It is a unique center dealing with a wide variety of disciplines comprising design and development of payloads, societal applications, capacity building and space sciences, thereby creating a synergy of technology, science and applications. SAC operates and maintains Ahmedabad Earth Station and the Delhi Earth Stations.

My internship started in January and it will end in June.

First off, I met several scientists and engineers to discuss my options of a project then I decided to go for project, which involved FPGA and Signal Processing. I always wanted to work on FPGA’s so this was the opportunity I did not want to lose.

I met my mentor, Shri T. V. S. Ram. APD, Nav-Payload, SAC and he fully explained to me what I was to do in the project and asked me to give my 130% to complete this project (for him even 100% was not enough). The level of seriousness can be understood from the fact that you are not allowed to carry the following: cell phones, pen drives, laptop, earphones, CDs or any other electronic item.

The project, which I am working on, gives exposure in both the areas; software as well as hardware. This is the first time I am experiencing working in an organization and also the first time for me to realize that our work really matters as it affects millions of people indirectly which brings in me, a sense of responsibility.

One of the major parts of the project is testing, which I have not yet done for college projects. Here, a good amount of time is invested in testing modules, leaving no stone unturned, before pushing it into the production.

The benefits of working in ISRO are immense, you feel proud of working at one of the most reputed organizations around the globe. You get to see different labs; different technologies being used. I got the opportunity to see the satellite getting gruesome (Thermovac testing). Recently, on women’s day celebration, the chief guest invited was one of the survivors of the Pan Am flight hijack, the Neerja episode. It was a thought provoking experience.

SAC has a big theatre that shows live launching and I witnessed the launch of IRNSS-1F, 1G and RLV (Re-Launchable Vehicle) on that big screen, what a view that was. In addition to this, I got opportunity to see the satellite (payload) being flag off from SAC, Ahmedabad to ISAC, Bangalore.

This, I would like to point out, was a very good experience for us because here we had to develop something for them and it was more of a challenge.

On a concluding note, I think my internship experience has been amazing because I got the chance to do a project on my own and I managed to put in all my efforts and did my best. The internship put in a lot of confidence in me because it is a very good feeling when you make a project on your own and it is accepted by various departmental heads.


Gunjte Alfaaz

Sometimes, when you look out of the window on a lazy summer afternoon, you start contemplating.

The sun is soaring; all the trees and plants merely bow down to the glare giving shade to the sleeping dogs that have no purpose in life. Everything seems… static.

But is that how life’s supposed to be?

The clocks ticks away, the weather changes and everything is suddenly in full motion. The summer afternoon was simply a phase.

We need to get out of our  dull phases and look at life from a new perspective.

Gunjte Alfaaz is a song that talks about how life is so much more than just 70 years of existence. There is so much to see, so much to learn and so much to be inspired from, even from the drops of rain that cheer us as they fall from the mighty heavens.

The song was written by Venugopal Shah with the help of Madhawam Agrawal of IIIrd year. It was later on composed and sung by Venugopal and Pravit Tuteja and Yash Saxena completed the song by featuring on the guitar.

The song is written in Hindi, and the music genre is ambient.


Kyu teri zindagi, ruki hui si lagti hai

Ik baar tu aankhe kholde zara

Teri hi hai yeh zameen, tera aasmaan


Pal yeh pal jo chale jate hai, kyu tujhko tadpaate hai

Mere yaara sunle zara

Kehti hai kya tujhse yeh khamoshiya


Teri hi hai yeh duniya, khudh ko bhula mat tu

Matlab tu dhundta kyu, khud me samaya hai tu


Kyu yeh madhoshi me, tu jee raha hai

Hai ghadi ke kaante tere aage

Jab tak tu na uthe, uthke bhaage


Kyu tere kadam ye, yu tham se gaye hai

Yu na muh modh le, aage badhta ja

Rasta roke koi, tu na ladhkadha


Teri hi hai yeh duniya, khudh ko bhula mat tu

Matlab tu dhundta kyu, khud me samaya hai tu


Sahaara le tu apni panah se

Gunjenge alfaaz tere iss jaha me

Chal ab saath tu mere yaara

Tujhko pukaare yeh jahaan saara


Kyu is dil ki dhadkan, khamosh ho jati hai

Ik baar tu bhi iss junoon me jhum zara

Jaise baarish ki bundo ki mastiya


Teri hi hai yeh duniya, khudh ko bhula mat tu

Matlab tu dhundta kyu, khud me samaya hai tu

Dhal jayegi yeh raat, chhodna mat tu apna saath

Tu jeeya hai, aur jiyega, kehti hai teri harr saans

They released the acoustic version of the song on YouTube at the following link:

Happy Mother’s Day

I am your mother,

You are my child.

I am your quiet place,

You are my wild.

I am your calm face,

You are my giggle.

I am your wait,

You are my wiggle.

I am your dinner,

You are my chocolate cake.

I am your bed time,

You are my wide awake.

I am your lullaby,

You are my peek-a-boo.

I am your goodnight kiss,

You are my ‘I love you‘.

From the time we were born, until the age we are now, there has always been one person totally invested in our happiness: mother.

All she wants in life is to provide for us and protect us. A mom’s unconditional love is truly unmatched.

Here are the  ways in which our moms are our first best friend.

  1. She always comes to your defence.
  2. She genuinely cares about what you’re doing with your life.
  3. She endured Disney in all forms just to see you happy
  4. She’s the only one who cares if you wore a sweater. Or brought an umbrella, or needed a tissue, or had a bad dream, or ate enough for dinner. Mom thinks about all the little stuff that has a big impact on your well being.
  5. She’ll always give you the benefit of the doubt.
  6. She wants to see you succeed without any reward for herself.
  7. She makes you feel special. She’ll keep you on the phone for hours just to listen to the most trivial parts of your day. She’ll take the time to stock up on your favourite foods when you’re only coming home for a weekend.
  8. She cares about your appearance more than you do.
  9. She’ll celebrate your birthday more than her own.
  10. She’s the only person who knows how to shop for you.
  11. She’s always down to split her meal with you. And then eat less of it because she’s suddenly really full. She really always wants the best for you, even when it’s just lunch.
  12. She loves to listen to you brag. Besides your grandma, your mom is the only other person who genuinely likes to hear about your extensive accomplishments. Even if it’s something as small as, “I made my own lunch today!” Mom wants to know about it.

We love you mom.

Happy Mother’s Day

62 million tones of garbage is generated everyday by the 377 million people living in urban India, now the world’s third-largest garbage generator. India’s 4378 municipalities spend a lot of money handling waste. Between 10 to 50% of the municipal budget is allocated for solid waste management (SWM). An average class I city spends 330 Cr annually on SWM. Of this, up to 70% of the funds are spent on collection, 20% on transportation and only 5% on disposal. Not only this, but between 30-50% of the total staff are typically engaged in SWM.Despite investing all these resources, Garbage Pollution is still a problem fast becoming a threat.

With urbanization and increasing population it is predicted to double within the next 10 years. At this rate, if not managed well, it will not be nuclear war or global warming, but the garbage we generate everyday that will threaten our sustenance.

But, it doesn’t have to be this way.

We can change it.

We are entering an era of IoT. 4 years from now about 20 billion objects will be connected to the internet ranging from the shoes we wear to the appliances we use. This will unleash a level of connectivity which will enhance our decision making abilities and make our lives easier and more efficient. This powerful technology has opened up a way to solutions that were not possible before. Smartbin is one solution.

The current practice of garbage collection is for the garbage van to visit all bins in an area periodically once in 2-3 days, for collecting. But since bins fill up at different rates, bins that fill before period overflow and those that take longer don’t need to be emptied yet. Evidently this method of collection based on time crevices is an ineffective and a very wasteful one. We need smarter criteria, based on definite information, not just wild guesses.

Smartbins are a network of dustbins equipped with sensors that analyze the fill-level data of bins in real-time so that pick-up schedules can be generated based on location, filled levels, or time remaining till overflow. It shows optimum routes to only filled bins. It allows the admin to monitor collection process and provides users the shortest path to the nearest empty bin for use. It also provides a mechanism for prompt feedback and redressal complaints are received by admin in an order of priority.

Lets talk about what makes smarbins awesome.

Smartbins will increase the efficiency of garbage collection and eventually lead to cleaner communities. Collecting the most amount of materials in the least amount of time to reduce costs and emissions along the way. It can save up to 50% in collection costs for its municipal, commercial and industrial customers. It will also lead to reduction in air pollutants from fuel emissions and fumes from overflowing garbage that sometimes locals burn, to get rid of it.

The network technology we used is LoRa WAN. It is a wireless technology developed for the low-power wide-area networks (LPWANs) used in machine-to-machine (M2M) and LoRa is a wireless technology popular with Internet of Things (IoT) applications.It offers a very compelling mix of long-range, low-power consumption, and secure data transmission. A network based on LoRa wireless technology . Many mobile network operators have chosen to complement their existing cellular/wireless networks with a LPWAN based on LoRa technology because it is easy to plug into their existing infrastructure and allows them to offer their customers a solution to serve more IoT battery-operated applications. It is key to smart cities because this network is capable of running several other IoT applications on it simultaneously, on top of SmartBins.

To conclude, I’d say SmartBins can prove to be pivotal in the realization of a Swchh Bharat and the Smart City Vision.

The Inception
We have centre for Excellence in banking and finance at NU. We thought why can’t it be a “Think tank” that can comment on policies? or better still, that can suggest new policies and can give solutions for the economic issues in the field of banking and finance !
That was the vision we had when we started working on this project.
Secondly, today, the Banking sector in India is facing 2 prime issues :
1. The ever increasing NPA
2. Implementation of BASEL III norms
Especially, the state of the public sector banks (>51% govt. share) is alarming. We have more than 5 lakh crores of stressed assets (Restructured assets and NPA’s) and we have to infuse 2.5 lakh crores under BASEL III.
These were the two prime reasons we led to the vision and motivation for this work.
Prof. Arun Kumar is the brain child of this whole idea. He has motivated us and given us a direction. He is a seasoned banker with more than 30 years of experience and his role was instrumental.
Our Story and Experiences:
When I came up with this idea, I was looking for a partner. A co-author is important, because your partner and you, together, can act as a self help group and the engine keeps moving. So I contacted Ganesh.
We started gathering data. Our university has access to Capitaline that proved to be very useful for this task of ours. We also read a lot of papers that became the backbone of the basic framework and finally, we focussed on quantitative tools like regression on SPSS for analysis.
Initially it was difficult to pacify people, even in the faculty review because “Research in banking”  was a new concept for many. But when our paper got accepted in a few journals, it boosted our morale and we could instill the confidence and faith that we had in our project, in others too.
We submitted the article for consideration in 3 journals and luckily all of them accepted to publish it. We finally chose the ‘International conference for Research in Business’.
We prepared well for our presentation which was to be held on 17th April and were determined to get the  prize for the best paper. There were 14 teams from Delhi university (Delhi School of Economics), one from the Orissa University , there was one from New Zealand, and one more from IIM Ahmedabad. The topics ranged from surrogate advertisements, to BRICS and FDI/FII, among the many others.
We would like to thank NIIT University for its support. We would also like to give special mention to Dr. Sunil Khanna, Shivender Mathur sir and especially our mentor, Arun Kumar sir for all their guidance and support.

Life Queen Size!

A reason to travel India…

In a country where culture meets heritage with an integrity that itself defines the soul, Indian peninsula stands alone as the most colorful and vivid land within all the continents and oceans. From the depths of the Indian Ocean to the zenith of the Himalayas, the stretch of three thousand and two hundred kilometers amounts for life in all hues and styles.







The country is not only engraved with some of the oldest populations and architecture, its temples and forts date back to the earliest of centuries.

Indian heritage has always attracted intelligentsia and tourists from all over the world. One of the most important reasons behind this pertains to the sanctity with which Indians treat their guests. Be it the spices of our curries or the odour of our sweets, the melting of butter on paranthas or the grandeur of our thalis, any guest is offered all of this with a purity comparable to prayers. That is where “Atithi Devo Bhavah” originates from. From the high-end resorts to the smallest street shops, one can achieve and realize the aesthetic beauty and magnificence, specific only to a land which is embellished with the values of humility to the core.







The rivers that flow through the land carry the tradition of a thousand of years old civilizations and that can be felt like a heartbeat with every tiny flower petal that floats along in them. The sparkling zeal of tiny diyas, the fragrance of our gulaals, the breeze that flows through our farms, and the brightness of our festivities, all are wholehearted messengers of goodwill to every single individual that experiences them. No other place in the world can constitute the innumerable languages and races that India suffices for and there still rings the voice of love and brotherhood above all.

Travelling from one place to another in our country is itself a saga of merriment. No matter how fully loaded the buses are, or how stuffed are the train compartments, there are always titsy-bitsy conversations about anything and everything and folklores to watch out for. Wherever you go, dangling of bangles and cacophony of infants will follow you around like a background score. Once you reach to the insides of our temples, the rituals and artifacts are nothing less than legends. You can get lost forever amidst the glory of the forts and palaces that are woven throughout the peninsula.







Then there’s the nightlife of our beaches and hill stations which is incomparable in its own accord. When the sun rises in the country, the mountain peaks and forestry embrace it with open arms till it vanishes into the calmness of our seas. Ask for anything ranging from western style glitterati to typical native customs, and India has just the perfect places for you all served on a velvet platter of its soils.

Now if it’s still a moot point as to why India is one of the most loved tourist attraction and why should it remain so, I guess one should tighten a knapsack and start on a voyage throughout the ancient land where nature and purity resonate together with a harmony of resplendence.
