Is there an easy way to form the SVD of G from the SVD of A? Jim Epperson ------------------------------ From: Trini Flores Date: Fri, 28 Jul 95 09:47:24 EST Subject: Conference on Numerical Combustion Sixth International Conference on NUMERICAL COMBUSTION March 4-6, 1996 Le Meridien New Orleans Hotel New Orleans, Louisiana Conducted by SIAM with the cooperation of Institut National de Recherche en Informatique et en Automatique (INRIA) ABOUT THE CONFERENCE ... Advances in computational algorithms and hardware continue to have a revolutionary impact on the combustion sciences, and permit the examination of scientific and engineering problems of increasing complexity. The Sixth International Conference on Numerical Combustion will focus on the integration of theory, modeling, and numerical implementation in the study of basic combustion physics and technological applications. The distinct questions and challenges found in combustion and phase transition arise from the multiplicity of length and time scales defined by the chemical, geometric, and flow ingredients. Physically descriptive, efficient and accurate numerical modeling of complex phenomena is the subject of the conference. This conference is designed to bring together computational scientists, research and design engineers, and mathematical and physical scientists who are interested in the interdisciplinary area of numerical combustion. The conference will highlight the mutual interaction of designers, experimentalists, computational experts, and mathematicians in the development of new ideas and methods in the study of combustion. CONFERENCE THEMES The themes of the conference include, but not limited to: o Turbulence o Kinetics o Detonation o Flames o Pollution o Microgravity o Applications of parallel processing o Materials synthesis o Droplets and sprays o Ignition o Heterogeneous combustion o Energetic materials (propellants) o Simulation of internal engine and furnace combustion INVITED PRESENTATIONS The Transport of Combustion Products from Fires Howard Baum National Institute of Standards and Technology State-of-the-Art in IC Engine Combustion Modeling Sherif El-Tahry General Motors Research Laboratories Numerical Simulation of Premixed Flame Propagation in Closed Tube Kunio Kuwahara The Institute of Space and Astronautical Science, Japan Coupling of Chemical Kinetics with Flow and Molecular Transport Ulrich Maas Konrad-Zuse-Zentrum fur Informationstechnik Berlin, Germany Direct Simulations and Modeling of Flame/Wall Interactions Thierry Poinsot IMFT/CERFACS, France The Dynamics of Multi-Dimensional Detonation D.
