Sl. No.	Degree	Subject	Supervisor(s)	University	Year	Remark
1.	Ph.D.(Engg.)	Heat Transfer and Fluid Mechanics	Prof. Vijay H. Arakeri	I.I.Sc., Bangalore	2000	Our Problem was an adventure on a fundamental Physics Problem and we were successful in getting a fundamental result with Mechanical Engineering Background. We also did compressible fluid flow CFD analysis to support our experimental results.
2.	M.Sc.(Engg.) by Research	Heat Transfer and Fluid Mechanics	Prof. Mrityunjay Vijoy Krishna Murthy	I.I.Sc., Bangalore	1993	Condensation was a complicated Phenomenon and incompressible fluid flow CFD was extremely difficult as computer was very slow during that time. Further data storing was also extremely difficult. I had to repeat three times to get complete data set, as data was damaged due to storing problem. That's why publication was delayed. Finally, we were successful. In our time M.Sc(Engg.) wasn't time bound. Thesis was reviewed by outside Expert similar to Ph.D. programme and one can convert it to Ph.D.. Dr. GSVL Narasimham was indirect guide.
3.	B.E.(Mechanical Engg.)	Mechanical Engg.	B.E. College's all Mechanical Engineering, Applied Mechanics, Mathematics, Electrical Engineering and Electronics Engineering Faculties.	B.E. College/ Calcutta University	1989	I got job in USHA Martin rope wire in Ranchi. But I avoided to settle there; I planned to do higher studies. I scored 94.5 percentile in GATE in 1990 and also appeared IISc. integrated Ph.D. programme examination. I was successful in getting integrated Ph.D. Programme.
4.	H.S.(12th)	Science	All Teachers in Banamali Chatta High School, Sir Subhamoy Jana and Prof. Asraf Ali	WBCHSE	1985	I was successful in WBJEE with a rank of 403 out of around 4,50,000 H.S. students in West-Bengal in the year 1985. I was also first boy in our school.
5.	Secondary (10th )	Science	All Teachers in Kajlagarh M.S.B.C.M. High School and Sir Mrityunjoy Mandal	WBBSE	1983	I was Third boy in our School.
6.	8th Standard	Science	All Teachers in Bani Mandir School and Sir Pulin Bihari Das		1981	My friend Deb Kumar Bera and myself were successful in the Examination in getting Contai sub-division scholarship for class- VI in the year 1979 from our school. I was also first boy in our school. Possibly my father collected the certificate from my school. Probably money was written in the certificate which was spent for my other brothers and sister. That's why I never got the certificate in my possession. It may be possible that it was District scholarship. My Rank was 20 as said by my father. Institute Head rejected to allow me to go another school till class-VIII; as my father was interested for Class-VIII scholarship examination.
7.	Primary School	Science	All Teachers in Kalyachak primary school, my Eldest Aunt and her husband Mr. Bijoy Krishna Ghorai		1977	Four Friends including myself used to alter our position(Rank) in the examination.

*** I must acknowledge a defence personal, Mr. Dilip Bhunia (Senior most Subedar), who was posted in Tumkur(Karnataka), accompanied me during my difficult time in my Ph.D. Programme.

*** My father always used to promise to give a Scooter, if I do well in the examination. But I never got it and I never mind it either. But I was always self movitated one/two months before every examination in young age. In-and-after 12th Standard result, I was/am completely Self movitated.   

*** I also thank Prof.(Dr.) J. Srinivasan (IISc.) for his ability to put us into Sky (i.e., infinite domain or Mahaviswa in Hindi) during his lectures for his courses, with a word of caution that: how to get down one should learn. Exergy is one part of thermodynamics, which was taught by him. It seems to me Exergy analyses coupled with thermo-fluid ((some part is covered by Prof.(Dr.) MV. KrishnaMurthy, Prof. (Dr.) Vijay H. Arakeri, Prof.(Dr.) K.S. Gandhi, Prof.(Dr.) Kesab Rao and Prof. (Dr.) B.N. RaghuNandan, Prof.(Dr.) P.L. Sachdev, Prof.(Dr.) Dilip Patil, Prof.(Dr.)  Asitava Ghosal and Others  from IISc(Bangalore); and Some part is covered by Prof.(Dr.) Panna Pal (Thermal-Power Plant. And Thermo-Steam Turbine Laboratory jointly with Prof. (Dr.) Achin RoyChoudhuri, Prof.(Dr.) Pradip Dutta), Prof. (Dr.) D.N. Roy, Prof.(Dr.) Asimava Ghosal, Prof.(Dr.) Binay N. Dutta, Prof.(Dr.) A. Talapatra, Prof.(Dr.) Susital Roy, Prof. Alok Das, Prof.(Dr.) Tapen Moulic, Prof. Ashok Ghosh, Prof. S. Sengupta, Prof. D. Sengupta and Others from B.E.College, Howrah, West-Bengal, Bharat(India))) have good prospects and may create huge (sky-high prospect) number of Jobs all over the world, provided huge knowledge are gathered by one's own from the basic knowledge imparted by teachers, as Industrial problems are extremely challenging. I am extremely thankful to my all Gurus including all Faculties and Scientists in IISc Mechanical Engineering, Other Departments and Centers. I am also thankful to IISc Non-Academic Administrators, Technical and Non-Technical Staffs as well as B.E.-College Non-Academic Administrators, Technical and Non-Technical Staffs.  

*** Probably I got NTSE(Year-1983; I appeared in the Examination in Midnapur Town; School I forgot) also. It had never been disclosed; the reason was same as in class-VI. It is my guess. After securing 760 marks out 1000 marks in H.S., my middle brother told me, I missed govt. scholarship by 2 marks ( i.e., If I got 762, I would have got Govt. Scholarship). Highest scorer was around 870 marks in my time. So, he asked me to apply loan scholarship and I filled up the form and my middle brother did the remaining thing. Now I am analysing the matter. As I was getting NTSE scholarship without my knowledge from the Indian Govt., I was ineligible for Govt. Scholarship. If I got NTSE, now I thank my friend Suman Ghosh (First boy) as I had the opportunity to talk with him in his Father's quater one day or two after Madhyamik(10th) Examination regarding NTSE(NTSE means National Talent Search Examination) and otherwise also he was my good friend. 

*** I also thank Prof.(Dr.) Meheboob Alam (my B.E. College & IISc. friend) for his approach to provide  information on relevant books whenever I asked for any discussion. I also Thank Prof.(Dr.) Sumit Basu (IISc. Friend) and later on Dr. Hyun Sun Park (Post-Doc. Friend) for providing relevant information on Matlab.  I also thank Prof.(Dr.) M.R. Rabi and later on Prof.(Dr.) Sangeeta Kohli (both of them are senior IISc. Friends) to Keep our IISc. Mech. Engg. computer laboratory 24 Hrs. open, especially for Dot-Matrix printing free-off-cost (of course the Honourable Departmental Chairman's role cann't be denied), as printing was costly compared to our Scholarship. Further, I also thank the SERC(IISc. Super-Computer Center) Honourable Chairman, Scientists, and supporting staffs for providing free-off-cost software/data printing facilities and keeping it round-the-clock open. I also thank Prof.(Dr.) Anupam Dewan (IISc. Friend) for a computational discussion useful for both of us during my master Degree programme.

3.	23/1/2001	31/12/2003	I was next to Co-ordinator as well as the Head of the Department Prof. Bal Raj Sehgal for European-Union collaborative (Participating Countries: Sweden(KTH-Stockholm), Germany (Stuttgart-University), France (Framatome-ANP), USA(UCSB-California), Finland (VIT Energy), Hungary(VEIKI, Budapest)) Projects costing 0.5 million Euros on Nuclear Power Safety after Dr. Anand Sundarrajan Theerthan left Sweden on around June/July 2001, as Anand got faculty position in IIT-Bombay as well as GE(Bangalore). I used to present my work performed in the group meeting held in the said European countries and prepare minutes of the meeting except USA and France. But I visited Spain for a meeting connecting our project and another Group's(USA) project (similar type of work) which was handled by Prof. Michele Koradini and Co-workers, as both the works were common interest of nuclear power safety of the society of our sphere.

Gandhi, who offered a course on Interfacial Phemenon and Prof. Vijay H. Arakeri suggested me to take this course. It was mandatory in the course work to give one 30 minutes lecture individually by slide presentation(during that time). 30 Marks was allotted in the lecture. Lecture should be physics based with a little bit of mathematics. I gave lecture on contact angle dynamics of liquid droplet on a solid surface collecting and analysing around 40 papers during my Ph.D. course-work and it shouldn't be my Ph.D.  topic. Nobel prize winner Dr. Robert D. Genes (from France) has publications on this topic. Further, Prof. Vijay H. Arakeri brought nano-particle from one of his friends (possibly Prof. M.S. Hegde) in I.I.Sc. and asked me to put in the acoustic resonator to do some experiments. It was not so much useful that time. But I gained some knowledge. In Sweden, Dr. Hyun Sun Park asked me to work on nano-fluid and asked me to write a project. But that time I was a little familiar about its prospect. Therefore I acknowledge Prof. Vijay H. Arakeri, Prof. K.S. Gandhi, and Prof. Hyun Sun Park for this outcome in the form of paper. I also acknowledge Dr. Anand SundarRajan Theerthan and Prof. Bal Raj Sehgal as I got an opportunity to work in Sweden as a Researcher and Hence develop communication with Prof. Hyun Sun Park. I also thank Prof. Kanagaraj Subramani as he allowed to use nano-particles flotation instrument by means of acoustic cavitation, sophiscated liquid conductivity meter probe, viscosity meter probe to Mr. S. Das. I also thank Chemical Engineering Department of IITG to take photographs of liquid nano-fluid droplet for contact angle measurement and absorption spectra measurement and this was communicated by Prof. Subramani Kanagaraj with my request, as Journal reviewer asked for it. I also acknowledge Tezpur University for providing the instrument to measure the size of nano-particles. I also thank NERIST Forestry department for allowing the microscopic photography for the evidence of nano-particle deposition on the solid surface, as Journal reviewer asked for it. I also thank Prof. N. Yadav (Chemistry Department, NERIST) to allow scholar to use his sophisticated Vaccum pump in his laboratory and I also thank NERIST Chesmistry Department. What it is meant by Journal Rreviewer asked for it is that first author was getting rejection from multiple journals with various comments, which has finally been culminated to Thermal Science Engg. Applications-An ASME Journal. Fund was provided partially by NERIST, partially by TEQIP-II, partially by myself. For example Data logger was procured by me, but Mr. Maibam Romio Singh interfaced data-logger with software.)

We bought aluminium plate, but machining aluminium plate is very difficult. From Aluminium plate we had to develop fins of duel height. EDM was necessary. When work was started, North-Eastern region was almost in a dark age. We had to take help of outside the North-Eastern region. Thermocouple wire was procured, but thermocouple beads were made outside. We had to calibrate thercouples made by us. We needed controlled environment to do the experiment and hence Air-conditioner was procured (with my own money). We had to develop validation set-up, as reviewer asked for it. We had to procure phase change materials. We had to procure DC source (with my own money) for controlled power supply to the heater, as power fluctuation is havoc in this region. One more data logger was procured with my own money. Moreover, we had to test the experiment many a times to get a conclusion. Initially, Scholar was upset, as expectations were delaying; although we (other scholar and guides) got numerically some interesting results. Guides only understood frustrations of the scholar. Finally, we achieved the good results. There are many difficulties: as for example measuring the amount of phase change material in every experiment, extreme care to be taken to avoid breakage of thermocouple beads, measuring density of phase change material by his own, measuring specific heat capacity by his own, etc. Fund was provided partially by NERIST, partially by TEQIP-II, partially by myself.)

Scientific Achievements:

(1). Recently we are able to relate fin heat transfer with the governing parameters by a very simple linear line, which will be very much useful for the designers of heat exchanger for a flow in the laminar range. Although this relation is obtained from the Computational method, but our results validate the experimental results within less than 6%. Here our group are Dr. Maibam Romio Singh and myself. 

(2). Finding effective heat transfer from variable fin-height (Numerically as well as Experimentally) by our group (Dr. Kankan Kishore Pathak, Dr. Maibam Romio Singh, Prof. Biplab Das, Dr. Debayan DasGupta, Prof.(Dr.) Pradip Lingfa and myself). It also requires lesser materials and hence it has double benefits.

(3). Our Experimental work on (1/10) th scale pressurised Nuclear Power Reactor Vessel failure and its management to cool the reactor vessel through gap cooling finds a special space in the European Union and it is very much useful for the safety management of present pressurised nuclear reactors. Our group consisted of the European Union and the USA.

(4). My Ph.D. work (both Experimental and Numerical) on Multi-bubble Sonoluminescence
(MBSL) and a Few bubbles Sonoluminescence (FBSL) is one of the most fundamental works in sonoluminescence.

******** Cyber Security and loosing mobile are two biggest threats to the Society of our sphere.  If one looses mobile, mobile thief can manipulate your personality.  Same is applicable for cyber security (for example: e-mail, there is a possibility of Journal/its-indexing by forming new (duplicate) existing web-site; it may be possible to modify Institute Web-site and thereby wrongly presenting Institute information for outsider away from the Institute; it may be possible to project wrongly presenting some personalties' image in facebook; Even it may be possible to manipulate voice recording by artificial means with lip movement; Games may be manipulated; etc. to mention a few) and it is a world-wide problem.

******** During Covid period, Prof. Suman Chakraborty's (IITKGP) invention on blood test patent instrument (which can test all blood related tests) came in facebook with voice in a video form. It seems blood test instrument can be made in Rs. 2000. Hence a vey very cheap (economically) test on blood related test can be done. Whether it is true or false can be judged now. If Prof. Suman Chakraborty did this blood test apparatus, then it is genuinely an excellent apparatus made by him and his group; but if such thing is fictitius, then problem is a very very serious issue as Dortors' Association will be annoyed on Prof. Suman Chakraborty because of completely false Gossip Technology. Doctors' Association will be annoyed on Prof. Suman Chakraborty because poor people can test their each blood test Rs. 5 to 7 with Prof. Suman Chakraborty's instrument, whereas they are paying currently more than around Rs. 200 for each blood test. So Poor people will be annoyed on Doctors.
