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.

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.

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
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
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
