Marie Curie Actions -- EST-SIGNAL

28 Junho 2007, 11:55 - Pedro Flores Correia

The European Doctoral Program in Signal Processing (SIGNAL) has been awarded funding (about 3.000.000 Euros) for 16 PhD grants + 9 short stays) from the EU Human Resources and Mobility program. These Early Stage Research Training Host Fellowships are the most competitive EU Marie Curie Actions. SIGNAL is a consortium of four universities.

Summer courses in Lisbon are:

"Stochastic hybrid systems and their applications to networks and biology"


João Hespanha, University of California Santa Barbara

Date: Friday 22/06/2007,
Time: 16:00,
Place: North Tower, Amphitheater EA5

Abstract: Hybrid systems combine continuous-time dynamics with discrete modes of operation. The states of such system usually have two distinct components: one that evolves continuously, typically according to a differential equation; and another one that only changes
through instantaneous jumps. We present a model for Stochastic Hybrid Systems (SHSs) where transitions between discrete modes are triggered by stochastic events, much like transitions between states of a continuous-time Markov chains. However, the rate at which transitions occur is allowed to depend on both the continuous and the discrete states of the SHS.
Several tools are available to analyze SHSs. Among these, we discuss the use of the extended generator, Lyapunov-based arguments, infinite-dimensional moment dynamics, and finite-dimensional truncations by moment closure. The application of these tools is illustrated in the context of multiple examples. We draw examples from diverse areas such as the modeling of network data traffic under TCP congestion control; the error dynamics in remote state-estimation over networks; and the evolution of the population of molecules undergoing a system of bio-chemical reactions.

Short biography: João Hespanha received the Licenciatura in electrical and computer
engineering from the Instituto Superior Tecnico, Lisbon, Portugal in 1991 and the Ph.D.
degree in electrical engineering and applied science from Yale University, New Haven,
Connecticut in 1998, respectively. He currently holds a Professor position with the Department
of Electrical and Computer Engineering, the University of California, Santa Barbara. His research
interests include hybrid and switched systems; the modeling and control of communication
networks; distributed control over communication networks (also known as networked control s
ystems); the use of vision in feedback control; stochastic modeling in biology; and the control of
haptic devices. Dr. Hespanha is the recipient of the Yale University's Henry Prentiss Becton
Graduate Prize for exceptional achievement in research in Engineering and Applied Science,
a National Science Foundation CAREER Award, and the 2005 Automatica Theory/Methodology
best paper prize.

Ciência Viva -- Ocupação Científica de Jovens nas Férias 2007

6 Junho 2007, 14:27 - Pedro Flores Correia

O Departamento de Engenharia Electrotécnica e de Computadores (DEEC) do Instituto Superior Técnico (IST) vai organizar, entre 16 e 20 de Julho de 2007, dois estágios no âmbito do programa de Ocupação Científica de Jovens nas Férias 2007, apoiado pelo Ciência Viva. Um dos estágios decorrerá no pólo da Alameda, e o outro no pólo do Tagus Park. Em ambos, o tema será a Engenharia Electrotécnica e de Computadores, estando as actividades laboratoriais concentradas na construção de robots: na Alameda robots para provas de Busca e Salvamento, usando as regras do RoboCup e Festival Nacional de Robótica, no Tagus Park utilizando veículos de corrida que seguem uma pista.
