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

0307475 Hesthaven在这三年的美国-法国合作研究项目，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，专注于开发和分析波浪主导问题的近似边界条件。这些问题是普遍重要的，涉及开发新的计算技术和改进的方法，在气候和天气，光通信和高速电子等不同领域的有效和强大的建模。将强调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）及其研究生和Elaine Becache，Houssem Haddar和帕特里克Joly（均来自INRIA Rocquencourt）组成。他们为这种合作带来了应用和计算数学（Hesthaven和Petropoulos）和数值分析（INRIA团队）的互补专业知识。这种联合的努力是需要开发拟议的新的计算技术，并了解所提出的模型的属性和局限性。 该奖项代表了美国方面对NSF和INRIA的联合提案。 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.
