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 […]
ADI Method for Sylvester Equations January 28, 2011 3:00 p.m. Ren-Cang Li Abstract We are concerned with numerical solutions of large scale Sylvester equations AX XB = C, Lyapunov equations as a special case in particular included, with C having very small rank. For stable Lyapunov equations, Penzl (2000) and Li and White (2002) demonstrated […]
Using Algebraic Multigrid For Numerical Upscaling October 13, 2010 2:30 p.m. Panayot S. Vassilevski Abstract We will give an introduction to multigrid methods (or MG) for solving systems of (linear) algebraic equations. We will first give a motivation why the method has the potential to be of optimal order, namely, that it can be […]
