Inverse Problems: Identification, Design and Control Date: Wed, 20 Nov 2002 FIRST CALL FOR PAPERS Fourth International Conference INVERSE PROBLEMS: IDENTIFICATION, DESIGN AND CONTROL July 2 - July 6, 2003 Boat cruise Moscow - Kostroma - Moscow by Volga river, RUSSIA Organized by: Russian Scientific Society "Inverse problems in Engineering" Moscow State Aviation Institute (MAI) Moscow State University (MGU) Bauman Moscow State Technical University (BMGTU) International Center for Advanced Studies "Cosmos" Objectives: Following the successful first, second and third conferences in this series (held in Suzdal (1990), in St.Petersburg (1994) and boat cruise Moscow-St.Petersburg (1998)) the aim of this Fourth International Conference is to bring together the scientists and engineers involved in inverse problems research and to provide a relaxed atmosphere for in-depth discussion of the types of inverse problems, which occur in engineering practice. At the final meeting (June 5, 1998) participants of Third Conference had decided to rename the future conferences from "Dynamic System Identification and Inverse Problems" to "Inverse Problems: Identification, Design And Control". The Identification, Design and Control problems dealing with unknown boundary and initial conditions, sizes and shapes of domains, physical properties of the media, governing systems of equations, and internal and boundary sources in the multidisciplinary fields involving thermodynamics, heat transfer, fluid mechanics, strength of materials, structural dynamics, electro-magnetics, and nuclear systems are all of interest and are welcome at this conference. Methods of interest include also efficient and robust numerical techniques (including optimization) that are being applied to cope with a wide variety of identifications problems. The behavior of numerical algorithms for the solution of these extremely conditioned problems and their critical evaluation by comparison with experiments or established benchmarks are highly desired. The conference is of importance to all scientists and engineers who are actively involved in developing innovative theoretical approaches as well as in solving practical industrial problems. The International Scientific Advisory Committee members anticipate that the conference will point out new directions in the identification of mathematical models, design of technical systems and control of dynamic processes. Conference Themes: The topics listed below should give only a general guideline for possible contributions. Papers on other topics connected with other Inverse Problems will also be considered if they fall within the objectives of the conference. Heat Conduction Thermal Radiation Diffusion-Convection Thermal Processes in Porous Media Thermal Processes in Composites Phase Change Processes Fire and Combustion Thermal Stability Vibrations and Structural Dynamics Acustics Electromagnetics Materials Processing Elasticity, Thermoelasticity, and Elasto-Plasticity Tomography and Inverse Scattering Gas-Liquid Flows Mechanics of Solids Nuclear Transport Optimal Experiments Design Analysis of Experimental Data, Signal and Noise Processing. Mini-Exhibition: There will be a small table-top exhibition of publications, hardware and software relevant to the conference themes. For more information please express your interest on the attached inquiry form. Short Course: Short Course on Inverse Problems in Engineering and Natural Sciences is planned during the Conference (every evening two keynote lectures). The Short Course will be sponsored by the Ministry of Education of Russia and it is free of charge for students and young scientists.

It offers outstanding atmosphere for both relaxation and excitement. The "Borodino" is a two-deck riverboat for 85 passengers with two restaurants, a sauna, a bar, two conference rooms, etc. Several historical sites are located lose by the river and will be visited, including Uglich (the town where the last son of Ivan the Terrible was killed), Yaroslavl (the largest city on upper Volga with a lot of historical and architectural sightings), Kostroma (the original place of Romanov's Dynasty), Myshkin and Plyos (two beautiful smoll provincial town). Also pre-conference tour and post-conference tour in Moscow can be arranged for interested parties. All reservations for the riverboat will be made through the Conference Secretariat.

His monumental work "The Theory of Determinants in the Historical Order of Development" in 5 volumes was published from 1890 (volume 1) to 1930 (volume 5). It covers the history of determinants from its foundation by Leibniz (1693) and Cayley (1841) to 1920. A sixth volume was being prepared when Muir died in 1934. Determinants arise not only in linear algebra but in many other parts of mathematics and science, such as combinatorial enumeration, graph theory, representation theory, symmetric functions, statistics, number theory, interpolation and approximation, tilings, special function theory, statistical mechanics, and theoretical computer science. Entries of the associated matrices can vary from just 0's and 1's (or 0's, 1's and -1's) to multivariable polynomials to special functions to general functions. Matrices whose determinants are to be evaluated can be unstructured or highly structured (e.g. Laplace, Vandermonde, Hankel, Fredholm, Toeplitz). For this special issue, we seek papers that, to name a few possibilities, advance the theory of determinants, provide special formulas for determinants, use determinants crucially in the context of solving a problem in another field, and give new application of determinants. In editing this special issue we seek to honor the legacy of Muir as well as to showcase the central role of determinants in mathematics. All papers submitted must meet the publication standards of Linear Algebra and its Applications and will be refereed in the usual way. They should be submitted to one of the special editors of this issue listed below by November 30, 2003.
