ELECTRICAL ENGINEERING - DISTINGUISHED LECTURER SERIESAbstract:Transient faults caused by external radiation or internal electrical noise are common in integrated circuits (ICs). They normally do no permanent physical damage, but they can produce complex logical errors that require probabilistic analysis techniques. The shrinking of ICs in accordance with Moore's Law is increasing susceptibility to errors of this type. Moreover, many of the nanotechnologies proposed to replace or supplement conventional ICs also have behavior, both normal and faulty, that is inherently probabilistic. In this talk, I will review transient faults and their impact. I will then discuss a method of modeling transient faults and a computational framework based on probabilistic transfer matrices for analyzing transient faults and errors in logic circuits.Bio: John P. Hayes is Professor of EECS at the University of Michigan, Ann Arbor where he holds the Claude E. Shannon Chair of Engineering Science. His teaching and research interests are in the areas of computer-aided design and testing; VLSI circuits; fault-tolerant systems; ad-hoc networks; and quantum computing. He received the B.E. degree from the National University of Ireland, and his M.S. and Ph.D. from the University of Illinois, all in electrical engineering. Prior to joining the University of Michigan, he was a faculty member at USC. Hayes was the founding director of Michigan’s Advanced Computer Architecture Laboratory (ACAL). He has authored numerous technical papers, several patents, and five books. He received the Michigan’s Distinguished Faculty Achievement Award in 1999 and the Humboldt Foundation’s Research Award in 2004. Hayes is a Fellow of both IEEE and ACM.HOSTS: Prof. Mel Breuer & Prof. Sandeep Gupta

Cooperative Networking - Searching For Algorithms in Logarithms

SPEAKER: Prof. Mehul Motani, National University of SingaporeABSTRACT: In the last 50 or so years, information theory has helped to characterize many fundamental limits of communications and has driven innovation at the physical layer. Moving up the protocol stack, networking for wireline networks is fairly mature but wireless networks have advanced in a somewhat ad-hoc manner. One of the main challenges is that nodes in wireless networks can interact and cooperate in complex ways, often blurring the line between physical and network layer functions. In this talk, I will describe some of my research work which falls broadly in the area of cooperative networking for wireless ad-hoc and sensor networks. On one hand, we look to network information theory to help us understand the limits of communication and cooperation in networks, e.g., relay, multiple relay, and interference channels. On the other hand, we design algorithms and protocols for cooperative networking, e.g., for multichannel MAC, directional antennas and collaborative signal processing. Combining these two approaches, we describe how information theory in a network setting can suggest efficient approaches to routing for cooperative relaying.BIO: Mehul Motani is currently an Assistant Professor in Electrical and Computer Engineering at the National University of Singapore. He graduated with a PhD from Cornell University, focusing on information theory and coding for CDMA systems. Prior to his PhD, he was a member of technical staff at Lockheed Martin in Syracuse, New York for over four years. Recently he has been working on research problems which sit at the boundary of information theory, communications and networking, including the design of wireless ad-hoc and sensor network systems. He was awarded the Intel Foundation Fellowship for work related to his PhD in 2000 and nominated for the Best Teacher award at NUS. He is on the organizing committees for ISIT 2006 & 2007 and has served on the technical program committees of MobiCom 2007 and many other conferences. He participates actively in IEEE & Sigmobile/ACM and has served as the secretary of the IEEE Information Theory Society Board of Governors.Host: Urbashi Mitra, ubli@usc.edu
