The title of this winter school is: Thermal Measurements and Inverse Techniques, a tool for the characterization of multiphysical phenomena. The main aim is to present some experimental and numerical workshops. This winter school is organized with the support of the SFT (Societe Francaise de Thermique) and the Eurotherm committee. You will find full details in the first announcement which is enclosed in the attached document. Furthermore, full information can be also found on the school web site: http://iusti.polytech.univ-mrs.fr/metti2005. We sincerely hope that you will be able to join us in Aussois next January.

The resort is located about one hour (by car) southeast of Pittsburgh. This meeting is the sixteenth in a series, previously called the Gatlinburg Symposia. The name honors Alston S. Householder, one of the pioneers in numerical linear algebra and organizer of the first four meetings. The meeting has traditionally been held in an isolated location and is very informal in style. Each attendee is given the opportunity to present a talk, but a talk is not mandatory. The format of the meeting includes scheduled presentations during the day and more informal evening sessions that are organized electronically shortly before the meeting. Spirited discussion is encouraged. At the meeting, the twelfth Householder prize will be awarded for the best thesis in numerical algebra written since 1 January 2002. We hope that the meeting will be attended by recent entrants into numerical linear algebra as well as more experienced researchers. We encourage attendance by core numerical linear algebra researchers, matrix theoreticians, and researchers in applications such as optimization, signal processing, control, etc. The Program Committee welcomes your contribution. The meeting facility holds only 125 people, however, so attendance may need to be limited. We are seeking funding to provide financial assistance to recent PhDs and others who might need it. For full consideration, the committee must receive your abstract by 1 November 2004. Information concerning the application process may be found at the URL listed above. Please use the format provided at the Conference Website http://www.cse.psu.edu/~zha/householder. The committee expects to complete the list of attendees and scheduled presentations by 7 January 2005. After reading the files in the Conference Website, if you have any questions about local arrangements, please contact the local arrangements committee at householder2005@cse.psu.edu. Local Arrangements Committee: Jesse Barlow (Penn State University) Hongyuan Zha (Penn State University) Daniel Szyld (Temple University ) Other questions can be directed to house-request@cs.cornell.edu The Program Committee consists of Angelika Bunse-Gerstner (Bremen) Tony Chan (UCLA) Alan Edelman (MIT) Nick Higham (University of Manchester) Roy Mathias (College of William and Mary) Dianne O'Leary (University of Maryland) Michael Overton (New York University) Henk van der Vorst (Utrecht) Paul Van Dooren (Louvain-la-Neuve) Charles Van Loan (Chair, Cornell University) HOUSEHOLDER AWARD XI Nominations are solicited for the Alston S. Householder Award XII (2005). The award will be presented to the author of the best dissertation in numerical algebra submitted by the recipient of a PhD earned between January 1, 2001, and December 31, 2004. The term numerical algebra is intended to describe those parts of mathematical research that have both algebraic aspects and numerical content or implications. Thus, for example, the term covers linear algebra that has numerical applications and the algebraic aspects of ordinary differential, partial differential, integral, and nonlinear equations. To qualify, the dissertation must have been submitted to fulfill requirements for a degree at the level of a United States Ph.D. Candidates from countries in which a formal dissertation is not normally written at that level may submit an equivalent piece of work. The Householder Award, given every three years, was established at the 1969 Gatlinburg Symposium (now renamed the Householder Symposium) to recognize the outstanding contributions of Alston S. Householder, 1904--1993, to numerical analysis and linear algebra. Entries will be assessed by an international committee consisting of James Demmel (University of California, Berkeley), Sabine Van Huffel (K.U. Leuven), Volker Mehrmann (TU Berlin) Charles Van Loan (Cornell University) Olof Widlund (Courant Institute, New York University). The candidate's sponsor (the supervisor of the candidate's research) should submit five copies of the dissertation (or qualifying work), together with an appraisal by the sponsor and at least one additional letter of recommendation supporting the nomination, by February 1, 2005, to Professor Olof Widlund Courant Institute 251 Mercer Street New York, New York 10012 U.S.A. The award will be presented at the Householder Symposium XVI, to be held May 23-27, 2005 at the Seven Springs Mountain Resort in Champion, Pennsylvania. See http://www.cse.psu.edu/~zha/householder. Candidates on the short list will receive invitations to the meeting. Previous Householder Award winners were F. Robert (Grenoble) in 1971, Ole Hald (New York University) in 1974, Daniel D. Warner (University of California, San Diego) in 1977, E. Marques de Sa' (Coimbra) and Paul Van Dooren (K. U. Leuven) in 1981 (shared), Ralph Byers (Cornell University) and James M. Demmel (University of California, Berkeley) in 1984 (shared), Nicholas J. Higham (University of Manchester) in 1987, Alan Edelman (Massachusetts Institute of Technology) and Maria Beth Ong (University of Washington) in 1990 (shared), Hong-Guo Xu (Fudan University) and Barry Smith (New York University) in 1993 (shared), Ming Gu (Yale University) in 1996, Jorg Liesen (Bielefeld) in 1999, and Jing-Rebecca Li (Massachusetts Institute of Technology) in 2002. ----------------------------- From: "Jiri Simunek" Subject: Postdoctoral Research Associate, U.
