Modern C++ Design for Modern Computer Architectures: Meta Programming for Higher Performance Computing May 2, 2011 3:30 p.m. Joel Falcou Abstract As emerging architectures becomes more powerful, they also become more complex to handle for regular users. In this context, building tools for a large variety of upcoming architectures (GPGPU, many-cores, clusters) is a major […]
Discontinuous Petrov-Galerkin Method for Steady Transport March 28, 2011 3:30 p.m. Victor Calo Abstract The objective of this work is to analyze and develop discontinuous Petrov-Galerkin (DPG) methods in context of isogeometric analysis. The DPG framework enables an automatic computation of test function spaces that guarantee numerical stability whereas isogeomtric analysis aims at the integration […]
Spatio-temporal Modeling of Mortality Risks using P-Splines: An Application to Brain Cancer November 30, 2010 2:30 p.m. Lola Ugarte Abstract Analyzing the temporal evolution of the geographical distribution of mortality (or incidence) risks is an important area of research in disease mapping. It might help to better determining the risk factors involved in the studied […]
Adaptive anisotropic meshing and Level Set for free surface and interface flow problems November 17, 2010 3:00 p.m. Thierry Coupez Abstract In this presentation a level set representation of moving free surfaces and interfaces is combined with anisotropic mesh adaptation. We introduce first the convected Level Set method using a convective time derivative with the […]
Surveillance for Emerging Space-Time Clusters February 17, 2011 3:45 p.m. Renato Assuncao Abstract The interest is on monitoring incoming space-time events to detect an emergent space-time cluster as early as possible. Assume that point process events are continuously recorded in space and time. In a certain unknown moment, a small localized cluster of increased intensity […]
