DISTINGUISHED LECTURER SERIES"Discrete Mechanics and Control"Dr. Jerrold E. MarsdenCalifornia Institute of TechnologyAbstract:This talk will outline new methods from discrete mechanics for stabilization and optimization of mechanical systems. The idea of discrete mechanics is to replace Hamilton's principle, possibly including dissipative or control forces, by a corresponding discrete version. These methods have led to the development of successful variational integrators for the dynamics of mechanical systems, including continuum mechanics. After reviewing this methodology for dynamics, we show how it is also useful for control. Optimization is illustrated using a fleet of hovercraft, underwater vehicles and spacecraft (with Oliver Junge and Sina Ober-Bloebaum) and for locomotion problems (with Eva Kanso).Bio:Jerrold E. Marsden received his PhD from Princeton University in 1968 in Applied Mathematics and is now the Carl F. Braun Professor of Engineering and Control and Dynamical Systems at Caltech. His primary current interests are in applied dynamics, control theory, and multiscale systems, especially how these subjects relate to dynamical and mechanical systems with symmetry, to numerical algorithms in computational mechanics, as well as to the dynamics and control of underwater vehicles in a dynamic ocean environment, and to astrodynamics and space mission design. He received the AMS-SIAM Norbert Wiener prize (1990), a Humboldt Senior Scientist award (1991, 1999), a Fairchild Fellowship (1992), a Max Planck Research Award (2000), and the SIAM von Neumann prize (2005). He is a fellow of the Royal Society of Canada and the American Academy of Arts and Science. He is an Editor of Springer-Verlag's Applied Mathematical Sciences Series and is on the editorial boards for a number of prominent journals in applied dynamics and mechanics. He currently serves as director of CIMMS, the Center for Integrative Multiscale Modeling and Simulation at Caltech, is on the Board of Trustees of SIAM, is on the Scientific Advisory board of the DFG Research Center "Mathematics for Key Technologies", Berlin and is the scientific co-chair of ICIAM 2011.Host: Prof. Edmond Jonckheere, x04457 ***A reception will follow the seminar at 3:00p.m.

"A New Scalable and Cost-Effective Congestion Management Strategy for Lossless Multistage Interconnection Networks"PROF. JOSE DUATODepartment of Computer EngineeringUniversidad Politécnica de Valencia, SpainThursday, September 22, 20052:00-3:00p.m.EEB-248[Refreshments will be served]Abstract:In this talk, we propose a new congestion management strategy for lossless multistage interconnection networks that scales as network size and/or link bandwidth increase. Instead of eliminating congestion, our strategy avoids performance degradation beyond the saturation point by eliminating the HOL blocking produced by congestion trees. This is achieved in a scalable manner by using separate queues for congested flows. These are dynamically allocated only when congestion arises, and deallocated when congestion subsides. Performance evaluation results show that our strategy responds to congestion immediately and completely eliminates the performance degradation by HOL blocking while using only a small number of additional queues.Bio:José Duato received the MS and PhD degrees in electrical engineering from the Technical University of Valencia, Spain, in 1981 and 1985, respectively. Currently, Dr. Duato is Professor in the Department of Computer Engineering (DISCA) at the same university. He was also an adjunct professor in the Department of Computer and Information Science, The Ohio State University. His current research interests include interconnection networks, multiprocessor architectures, networks of workstations, and switch fabrics for IP routers. Prof. Duato has published over 280 refereed papers. He proposed a powerful theory of deadlock-free adaptive routing for wormhole networks. Versions of this theory have been used in the design of the routing algorithms for the MIT Reliable Router, the Cray T3E supercomputer, the internal router of the Alpha 21364 microprocessor, the IBM BlueGene/L supercomputer, and the Cray Black Widow supercomputer. Prof. Duato is the first author of the book "Interconnection Networks: An Engineering Approach". This book was co-authored by Prof. Sudhakar Yalamanchili, from Georgia Institute of Technology, and Prof. Lionel Ni, from Michigan State University.Host: Prof. Timothy Pinkston, x04482 http://engineering.usc.edu/calendar/
