US-France Cooperative Research (INRIA): Approximate Boundary Conditions for Computational Wave Problems

0307475在这个为期三年的美法合作研究项目中，布朗大学、新泽西理工学院(NJIT)和法国国家信息学和应用数学研究所(INRIA)的研究人员专注于波浪控制问题的近似边界条件的开发和分析。这些问题具有普遍的重要性，涉及开发新的计算技术和改进的方法，以便在气候和天气、光通信和高速电子等不同领域进行高效和健壮的建模。重点介绍吸收边界条件和影响边界条件的问题和模型。美国-法国跨学科团队由Jan Hesthaven(布朗大学)、Peter Petropoulos(NJIT)和他们的研究生以及Elaine Becache、Houssem Haddar和Patrick Joly(均来自INRIA Rocquencourt)组成。他们为这一合作带来了应用和计算数学(Hesthaven和Petropoulos)以及数值分析(INRIA团队)方面的互补专业知识。这一联合努力是开发拟议的新计算技术和了解拟议模型的特性和局限性所必需的。这一奖项代表了美方对NSF和INRIA的联合提议。NSF为美国调查人员和学生访问法国提供资金。INRIA支持法国研究人员访问美国。

0307475HesthavenIn this three-year U.S.- France cooperative research project, researchers at Brown University, the New Jersey Institute of Technology (NJIT) and the French National Institute for Research in Informatics and Applied Mathematics (INRIA), focus on the development and analysis of approximate boundary conditions for wave dominated problems. These problems are universally important and involve developing new computational techniques and improved methods for efficient and robust modeling in such diverse areas as climate and weather and optical communication and high-speed electronics. Problems and models that absorb boundary conditions and effect boundary conditions will be emphasized. The U.S.- French interdisciplinary team consists of Jan Hesthaven (Brown University), Peter Petropoulos (NJIT) and their graduate students and Elaine Becache, Houssem Haddar and Patrick Joly (all from INRIA Rocquencourt). They bring to this collaboration complementary expertise in applied and computational mathematics (Hesthaven and Petropoulos) and numerical analysis (INRIA team). This combined effort is required to develop the proposed new computational techniques and to understand properties and limitations of the proposed models. This award represents the US side of a joint proposal to NSF and INRIA. NSF provides funds for visits to France by US investigators and students. INRIA supports the visits of French researchers to the United States.
