Taxonomy for the Automated Tuning of Matrix Algebra Software September 10, 2010 4:00 p.m. Dr. Elizabeth R. Jessup Abstract Linear algebra constitutes the most time-consuming part of simulations in many fields of science and engineering. Reducing the costs of those calculations can have a significant impact on overall routine performance, but such optimization is […]
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 isogeometric analysis aims at the […]
Construction of High Order Schemes for the Compressible Euler and Navier-Stokes Equations August 26, 2011 11:00 a.m. Remi Abgrall Abstract In this talk, I shall describe and analyze a class of finite element schemes that are able to compute solutions of the Euler or Navier-Stokes equations that may present very sharp gradients. The connection with […]
A Bayesian Framework for the Solution of High-Dimensional Stochastic PDEs March 19, 2012 4:10 p.m. Nicholas J. Zabaras Abstract Computer codes that model physical phenomena or engineering processes depend on a number of uncertain input parameters. In this presentation, we discuss the development of an efficient, Bayesian Uncertainty Quantification (UQ) framework using a novel treed […]
Bootstrapping Independent Component Analysis April 6, 2012 1:00 p.m. Zhuqing Yu Abstract: Independent component analysis (ICA) is possibly the most wide spread approach to solve the blind source separation problem. Many different algorithms have been proposed, together with several highly successful applications. There is also an extensive body of work on the theoretical foundations and […]
