A Fresh Perspective on Smart Systems and the Internet of Things

Speaker: Dr. G Venkatesh

Abstract

Do the terms “Smart Systems” and the “Internet of Things” stand for something really different or are they just jargon for old ideas such as remote sensing, remote control, intelligent control, telemetry, SCADA and M2M? If these terms do indeed signify new ideas, what are the implications for the research and development of such systems? The speaker will take the audience through his own journey trying to answer these questions, which could result in some fresh light on this over-hyped topic.

Monitoring and Operation of Water Distribution Networks for Smart Cities

Speaker: Prof. Shankar Narasimhan

Abstract

A Water Distribution Network (WDN) is an important infrastructure of a city used for providing water for domestic as well as industrial uses. WDNs are used to transport water from sources such as dams, lakes and ponds to spatially-distributed consumers at the demand points through a network of pipes, pumps, intermediate storage reservoirs, and valves such that their demands are met at desired pressures. Smart operation of urban WDNs is based on optimizing one or more performance metrics while meeting consumer demands and satisfying supply side and storage constraints. Most urban WDNs currently are poorly instrumented, badly maintained and operated intermittently. The systems are operated inefficiently both with respect to energy and water use. It is estimated that water loss from such systems is around 35-40%, and the water is also not equitably distributed.

The talk provides a broad overview of the problems and solution strategies that have been developed by his team for efficiently managing the infrastructure of future smart cities. Several of these techniques are likely to be useful in solving similar issues that arise in monitoring control and management of power distribution networks as well.

Phase: Unexplored Wilderness in Signal Enhancement

Speaker: Prof. Akihiko Sugiyama

Abstract

This lecture presents importance and possibilities of phase information in signal enhancement. Phase has not been given as much attention in signal enhancement as its counterpart magnitude. This is partially so because Wang and Lim had experimentally showed in 1982 that except for some conditions, accurate phase does not help improve the SNR. After three decades, signal processing applications have significantly expanded and some of the conditions not taken into consideration by Wang and Lim have come to the spotlight. Two examples covered in this talk are impact noise suppression and mechanical noise suppression. Consumer products that require these techniques have a huge market today. Use of phase information in such applications is explained with audio demonstrations.
