This workshop will concentrate on problems related to modelling, full and reduced-order approximations, control, and analysis of coupled nonlinear systems, phenomena, and processes. Many applied and engineering problems require dealing with coupled effects which are essential to a better understanding of complex systems behaviour. Appropriate tools to study such systems are based on systems of partial (deterministic and stochastic) differential equations expressing fundamental laws of physics. The workshop will focus on both physical coupling and algorithmic coupling, as well as on hybrid systems where continuous and discrete dynamics have to be treated concurrently. In many cases coupling requires dealing with interacting components which could be structures, fluids or solid media, while in other cases such interacting components could be given by several different fields such as mechanical and thermal, or electrical and mechanical, invoking a unification of two or more physical theories that have been considered separately before. Some such examples are provided by smart materials and structures technology based on new materials such as shape memory alloys, piezoelectrics, magneto- and electrorheological fluids, and magnetostrictive materials. We are interested in contributions dealing with modelling, numerical approximation, and analysis of such materials and structures. Many control systems, including those used in smart materials and structures technology, require dealing with coupled effects, and we are interested in contributions related to these issues which include control of distributed parameter systems. Papers on non-engineering applications of coupled systems (e.g., in biology, physics, and life sciences) as well as papers on the mathematical analysis of coupled systems, processes, and phenomena are equally welcome. Abstracts of talks to be presented at the CPPP-2004 are due by December 19, 2003. They should be submitted electronically to either Professor Roderick Melnik (at rmelnik@mci.sdu.dk) or Professor Ralph Smith (at rsmith@ncsu.edu) Further information about the workshop can be found at the CPPP Workshop web page: http://www.sdu.dk/Nat/MCI/rm/workshop2004.html ------ Subject: Tenth International Conference on Hyperbolic Problems From: Date: Fri, 14 Nov 2003 20:32:31 +0900 First announcement The Tenth International Conference on "Hyperbolic Problems: Theory, Numerics and Applications" September 13 to 17, 2004 Osaka, Japan Website: http://www.math.sci.osaka-u.ac.jp/~hyp2004/ The Tenth International Conference on "Hyperbolic Problems: Theory, Numerics and Applications" will be held at HOTEL OSAKA SUN PALACE, Osaka, Japan, from September 13 to 17, 2004. The objective of this conference is to bring together researchers, students and practitioners with interest in the theoretical, computational and applied aspects of time dependent problems governed by hyperbolic equations. The conference will provide a forum to exchange and stimulate new ideas from different disciplines, and to formulate new challenging problems that will have impact in applications. The conference will keep the traditional balance of this series, of blending theory, numerics and applications. The scientific program of HYP2004 is overseen by an international scientific committee chaired by S. Kawashima (Kyushu. Univ.) and A. Matsumura (Osaka Univ.). We have an impressive list of plenary and invited speakers.

Lo (NASA Jet Propulsion Laboratory - Caltech) and Josep J. Masdemont (Universitat Politecnica de Catalunya). The field of Astrodynamics research is experiencing tremendous growth. Advancements in science and technology are enabling missions with much more challenging goals. In response, many new techniques have been introduced to solve these demanding new mission design problems. The purpose of this Summer School is to introduce some of these new ideas to the broader community of practitioners and researchers from Space Agencies, Industry, and Universities. The hope is that through the exchange of ideas in an interdisciplinary but focused venue like this Summer School, the international space community would benefit from this cross fertilization of new ideas and practical experiences. This Summer School consists of six short courses of 6 hours each given by specialists in the field on the following topics: * Gravitationally assisted trajectories * Low energy transfers in the solar system * Solar sailing * Formation flight * Tethered systems * Numerical and analytical techniques Attendees are also encouraged to present short communications to the participants of the School at the daily poster sessions, especially on subjects relevant to the School. A book of survey articles based on the lectures will be published shortly after the conclusion of the Summer School. ------ Subject: PhD Student Position in Dynamical Systems in Barcelona From: Carles Simo Date: Wed, 5 Nov 2003 15:01:29 +0100 (MET) PhD Student Position in Dynamical Systems at Barcelona University The research group in Dynamical Systems at the Departament de Matematica Aplicada i Analisi, Universitat de Barcelona offers a PhD Student position to work in Dynamical Systems.

We anticipate awarding 8-12 two year fellowships for students who will begin the Program in the Fall of 2004. Fellowship stipends will be $27,500 for a twelve month period. NSF fellowship support is restricted to US citizens or permanent residents. The Nonlinear Systems Program is designed to foster research broadly on nonlinear systems that combines theory, computation and empirical data. Four thematic areas will be emphasized: 1. Complex Networks: We are exploring such topics as the World Wide Web, populations with hidden structure (e.g., the network of injection drug users in a major city), the resilience of ecosystems composed of hundreds of interacting species and mathematical patterns in the statistics of forest fires, earthquakes, and blackouts. 2. Machines and Organisms - Locomotion and Manipulation: We view organisms as part of a continuum of solutions to the mechanical challenges of locomotion, flight and manipulation. Comparing and contrasting moving machines and organisms enables us to understand both better. 3. Biological Pattern Formation: We are using theoretical models, novel visualization and data analysis techniques to study the dynamics of spatially extended systems in terms of defect structures and patterns such as scroll waves. We seek an understanding of complex phenomena like cell migration and heart rhythm disorders that involve a large number of dynamical degrees of freedom. 4. Gene Regulation and Systems Biology: Through the use of theoretical models and large-scale computation, and leveraging the enormous experimental investment by the biology community, we plan to develop biologically useful theories of large subsystems of cellular function, specifically in the areas of gene regulation, manufacture of RNA and proteins, and cell signaling. Program requirements consist of two courses in nonlinear dynamics and computational methods, a year-long interdisciplinary project, participation in an IGERT seminar, a summer internship and completion of a Ph.D. minor. Applications are coordinated through participating graduate fields at Cornell. Applicants should describe their interest in the IGERT program as part of the statement of purpose in their Cornell graduate school application. They should also complete the contact form on the web site http://www.chaos.cornell.edu/ (click on IGERT Fellowship and then Application).
