Title: Information, Communication and Computing

Abstract: The interrelationship between uncertainty and information (entropy) was established by Shannon in 1948 which constituted the mathematical basis for the theory of point-to-point communication. In the past two decades the communication paradigm has moved to point-to-multipoint and multi-user communication. More recently, distributed communication and computation has become hot topics due to applications involving machine learning and artificial intelligence. In this talk we will discuss the milestone developments that have taken place in the past several decades and the key issues in distributed communication and computation.

He has been a core member and instrumental in setting up National Centre for Flexible Electronics set-up with the help of MeitY, Govt. of Inida. He also co-ordinated the Nanotechnlogy Initiatives at IIT Kanpur. His main interests are in Physics of Electronic and Photonic Materials, specially inorganic and organic semiconductors. He specializes in designing characterization experiments for these materials and has set up a specialized Laboratory for optical and electrical transient studies includingDLTS (Deep Level Transient Spectroscopy) family of characterization. Currently he is also interested in display and electronic applications of polymers and small molecules. Thematically his research interests are in condensed matter physics with relevance to electronic applications and devices. Recently he has been deeply interested in development technologies related to the emerging area of Felxible Electronics, especially development of functional inks, devices and printing processes appropriate for large scale manufacturing of flexible electronics.

Title: Flexible Electronics: Challenges in Devices & Integration

Abstract: Following significant advances in organic electronic devices, flexible electronics has emerged as a distinct technology with potential to revolutionize many application areas beyond the capabilities of conventional electronics. Typical applications are based on large area implementation of displays, thin film transistors, sensors and photovoltaic devices. Though significant strides have been made in the development of technology from materials to devices, innovative applications and large area integration remain challenging. At IIT Kanpur, we have made concerted efforts to tackle many of the challenges at all levels of the technology from materials and devices to manufacturing with a focus on catalyzing industries in this emerging area. I will describe through typical examples some of our efforts in this direction with focus on functional inks for devices, development of print processes for integration, and the nature of applications that are finding traction such as in smart packaging and labels.

Prof. A. M. Kulkarni

Prof. Kulkarni is a Professor in the Electrical Engineering Department, IIT Bombay India. He obtained his BE degree in Electrical Engineering from the University of Roorkee, India in 1992, and his ME and PhD degrees in 1994 and 1998 respectively, from the Indian Institute of Science, Bangalore. His broad areas of interest are in Power System Dynamics, HVDC Transmission Systems and Flexible AC Transmission Systems (FACTS). Recently, he has focused on Wide Area Measurement Systems (WAMS) for stability and control. He has worked closely with utilities in India on several projects, including the Power System Stabilizer tuning exercise in the Eastern and Western regional grids and Sub-synchronous resonance studies.

Title: Understanding Power System Dynamics through Local and Wide Area Measurements

Abstract: Power system dynamic phenomena like unstable swings, loss of synchronism and system frequency changes have been studied extensively in the past. The advent of synchronized wide-area measurement systems has made real-life observations of system wide dynamics easily accessible to the power system community. While many of these observations are merely consistent with what has been well-known in theory, some observations like propagation delays in electro-mechanical transients are non-obvious as they are seen only in very large grids. Using measurements recorded over several years, it also is possible to observe changes in the system characteristics over the years. This talk brings out these aspects using real-life measurements in the Indian Grid.

Topics and Abstracts for the talks-

Two outstanding paradoxes in electromagnetics

Prof S C Dutta Roy

The missing energy when a charged capacitor is connected across an uncharged one by a zero resistance wire has not so far been satisfactorily explained. Argument will be given why the current radiation theory is untenable. Another paradox is that of an infinite lossless transmission line which presents a resistive impedance at the input and draws energy from the input source. How come? It will be shown that none of the explanations given in the literature is tenable in the light of rational thinking and arguments.

Telecom – A story

Prof S C Sahasrabudhe

Communications plays a very crucial role in human society. Most take it for granted without appreciating its criticality. The talk traces progression of the “Telecommunication System” over 100+ years – from non – electrical systems of yesteryears to the yet to be born 5G. But, it is not an historical account. It looks at some of the great thoughts and concepts that led to the communication systems as we know today. Some great people have contributed to the development of communication theory and practice – among them: Tesla, Marconi, De Forest, Hartley, Nyquist, and Shannon. Shannon, of course, stand tall amongst these tall people. The talk may dwell on his contributions a wee bit longer than of others. It will end with the vision of 5G, and end with the question- “Do we really need 5G”. This question will remain unanswered.

The recent explosive growth of structural biology

Prof M R N Murthy

Structural investigations on biological macromolecules using X-ray diffraction techniques may be assumed to have come of age in the early 1960s with the determination of the structures of two carrier proteins, myoglobin and haemoglobin. A more recent revolution in X-ray crystal structure determination has occurred due to theoretical advances in methods for phase determination, low cost of large scale computation, developments in techniques for recoding and automatically processing X-ray diffraction images, techniques to protect crystals from radiation damage, availability of sensitive X-ray detectors and very intense X-ray beams produced by synchrotrons, automatic interpretation of electron density maps and the ability to express desired proteins in suitable expression systems. The result of these developments is an explosion in the number of structures determined. While it took nearly thirty years to determine the first protein structure, a new structure is being determined every hour at present and the protein data bank has more than 150,000 entries. The lecture will be an attempt to describe the development in the methodology of structure determination, illustrate the fascinating results obtained and convey the excitement of working in this field.

Science of Nyquist Waveforms

Prof A K Chaturvedi

Nyquist waveforms have been known for more than 90 years but it appears the last word on them has still not been said. We will illustrate this with a couple of examples. The problem of maximization of in-band energy of a root Nyquist waveform, for a given bandwidth, will be discussed. We will end by presenting some interesting trigonometric identities arising from these waveforms.

Convergence of Technologies: A Gateway to the Future

Prof Ajoy Kumar Ray

Abstract will be available soon
