INTERVIEW WITH DEPUTYALRLETGHIESTRAR How do you wish to see EEE department after 5 years?I would say that we need to expand boundaries in a manner to provide students and the faculty an experienceto the outside world inside the campus, also the Visibility to other institutions, conferences and collaborationwith industries, facilitation of research laboratories, use of labs by domestic industries, igniting young mindsfor products and patents, improvisation in the quality of projects, thus improving standard of students. Tell us about your three phase of your life here at Karunya. What is your experience, you being as a student, teacher and as a deputy registrar?In all of these I was undergoing the art of learning, be it technical knowledge , values that are been learnt in the course of mycareer,flexibilitythatwasimpartedduringmy9yearsofstayinhostel.Igainedexperiencewhileworkinginvariousadministratormodules which lent me flexibility as I dealt with parents knowing issues of students and handling their problems. On thewhole I would simply say I procured, bestowed, divulged, refined, cultured my knowledge that I could possibly get from here. How do you manage yourself being as a teacher and a deputy registrar?Being deputy registrar to the institution is my career and teaching is my passion, thus it’s effortless for meto cope with both, my pleasure is to create interest in students and thus making them trained professionals. How far CBCS system imparted improvement?Basically CBCS system provides student a free will to choose their professor, time and above all choice of the subjects andthus this can greatly give a positive outcome. Also I’m looking forward to see projects which are interdepartmental, inter-disciplinary since the students are now grouped in class where they study with their friends from different departments. What is your contribution after being a deputy registrar?I would include the improvisations that are done, the amount of scholarship that are being sanctionedhave increased to almost higher than previous records, also the quality of the course completioncertificate has also been improved , not that i forget , even the id cards have got their new traits.Dr.Albert Rajan 5

JET LAG FROM AdLrL.lyTdHiEa Karunya University entered into a Memorandum of Understanding with Technion-Israel Institute of Technology, a science and technology research university, dedicated to the creation of knowledge and development of human capital and leadership for the advancement of the State of Israel and all humanity in the year 2013. To intensify our collaboration, a group of faculty members from Karunya University visited Technion Campus in November 2014. I was a member of this team and it was during this visit that I learnt about the opportunity of a post-doctoral position in the department of Electrical Engineering. I deem it a great privilege and a God-given opportunity to step into the portals of Technion- Israel Institute of Technology, Haifa, Israel as a post-doctoral fellow. I work along with Dr. Yoash Levron in the area of Smart grids and Advanced Power system algorithms. The department of Electrical Engineering is a center of excellence in applied and theoretical research, contributing to the advancement of knowledge in electrical and computer engineering.Georg Simon Ohm In 1827, developed one of the most important laws of electric circuits: Ohm’s law. When the law was first introduced, the supporting documentation was considered lacking andGerman (Erlangen, Cologne) (1789–1854) foolish, causing him to lose his teaching position and search for a living doingPhysicist and Mathematician odd jobs and some tutoring. It took some 22 years for his work to be recognized as a majorProfessor of Physics,University of Cologne contribution to the field. He was then awarded a chair at the University of Munich and received the Copley Medal of the Royal Society in 1841. His research also extended into the areas of molecular physics, acoustics, and telegraphic communication. 7

RESEARCH 13 Dr.Jayakumar Associate Professor IEEE 802 SERIES INFORMATION AND COMMUNICATION PROTOCOL FOR SMART GRID APPLICATIONSObjectivesThe Electricity Department of Tamilnadu was laboring with old metering systems char-acterized by error prone manual meter reading, lack of visibility of peak demand periodsand inefficiencies in energy accounting due to tampering issues and power theft.Therefore a smart grid technology is predicted to reduce distribution losses, improveelectricity efficiency in the grid as well as at energy user’s homes and offices, and ena-ble two- way digital communication to monitor devices associated with the grid from acentralized control center. Consumers also would benefit from reduced electricity bills,greater reliability and quality of power supply by using this technology.This research proposal is modeled and implements the smart grid technology in a small-er level. This proposal focuses on the following use case.a. Reduction in power lossb. Identify the unauthorized usage of loadc. Demand responsed. Indicate the utilization of power at low tariffe. Excessive power utilization detection. Based on the above use case, smart grid proto type model will be developed andimplement for testing purpose. After the successful implementation, this model will beproposed and will be tested on few consumers in Coimbatore district with the help oflocal Utility Company.The research proposal revolve around energy, technologies such as smart metering,wireless sensor networks, open platforms, high-speed broadband and cloud computing,citizen involvement, and public administration services. University Grand Commission ( UGC) has selected the above proposal ( Ref.No.F.30-1/2014/RA-2014-16-OB-TAM-5600-SA-II) . UGC has grant Rs 29,24,424/ to completethe project with in period of two years (2015-2017).André Marie AmpèreFrench (Lyon, Paris) Mathematics, On September 18, 1820, introduced a new field of study, electrodynamics, devoted to the effect of(1775–1836) École electricity in motion, including the interaction between currents in adjoining conductors and theMathematician and Polytechnique in interplay of the surrounding magnetic fields.

TECH BITS 143D printing3D printing, also known as additive manufacturing (AM), refers to various pro-cesses used to synthesize a three-dimensional object.In 3D printing, successivelayers of material are formed under computer control to create an object.Theseobjects can be of almost any shape or geometry, and are produced from a 3Dmodel or other electronic data source. A 3D printer is a type of industrial robot.Futurologists such as Jeremy Rifkin believe that 3D printing signals the begin-ning of a third industrial revolution,succeeding the production line assemblythat dominated manufacturing starting in the late 19th century. Using the powerof the Internet, it may eventually be possible to send a blueprint of any productto any place in the world to be replicated by a 3D printer with \"elemental inks\"capable of being combined into any material substance of any desired form.3D printing in the term's original sense refers to processes that sequentiallydeposit material onto a powder bed with inkjet printer heads. More recently, themeaning of the term has expanded to encompass a wider variety of techniquessuch as extrusion and sintering-based processes. Technical standards generallyuse the term additive manufacturing for this broader sense. How Lexus Hoverboard WorksMagnets. That’s the short version. The long version means steeling yourself for a light dose of phys-ics.According to Lexus, its hoverboard relies on superconductors and magnets, which combine torepel the force of gravity and lift an object—like, say, a fancy skateboard and its rider—abovethe ground.“With a superconductor you don’t need to have anoscillating magnetic field [like Hendo’s],” explains EricPalm, Deputy Laboratory Director at FSU’s NationalHigh Magnetic Field Laboratory. “Instead you havesomething called the Meissner effect, which essentiallysays that when you take a magnetic field near thesuperconductor, it induces current in that supercon-ductor, and creates essentially an image magneticfield on the other side of the superconductor. Youcreate current, but since it’s a superconductor, thecurrents don’t die away. So you don’t need oscillating magnetic fields. You can have a magnetthat levitates above a superconductor or vice versa, a superconductor that levitates above amagnet.”If that all sounds a little technical, try to picture a maglev train, which relies on similar principles toachieve speeds of, in the case of Shanghai’s Transrapid, over 300mph.

MIRACULUM Dr. PRAWIN ANGELOne of the greatest witnessing tools we have available TESTIMONYto us is the testimony of a changed life and sharingone would be my privilege. Yes, my name is Geethanjali(2015 batch student (Btech EEE)), my 3- years of stay inthe department was awesome. I had a good time of ex-ploration of knowledge from the opportunities provided,it molded me to become a professional. Also I thank all the staffs for their supportive aid.Not that I forget, I even encountered myself in experi-encing wax and wanes. But God was so faithful thathe proved his unconditional love, I’m blessed with twoplacements (Infosys and Wipro), also I was able to top 7th semester subjects. And I came out as the beststudent of the year in the department. I no longer lookat unfair situations from a powerless point of view, butmore with an optimistic point of view. My testimony hasnot just ended and I’m excited where it takes me ,Ilearned a lot about both myself and the world that I never had even considered investigating. I wouldhighly recommend readers to get their boundariespushed. God blessed me with these achievements andI thank God and the department which became my family. #knowyourguru Describe the one thing that fascinate you and about you?
