Sampling techniques for uncertainty propagation in stochastic PDEs Alireza Doostan Dept of Aerospace Engineering Sciences, CU Boulder Date and time: Tuesday, October 25, 2011 - 3:45pm Abstract: The talk will start with a brief tutorial on polynomial chaos methods for stochastic PDEs, followed by a presentation on sampling techniques for...

Colloquium: Bengt Fornberg

Jan. 15, 2010

Radial Basis Function Methods for Solving Partial Differential Equations Bengt Fornberg Applied Mathematics , University of Colorado Boulder Date and time: Friday, January 15, 2010 - 4:30pm Abstract: For the task of solving PDEs, finite difference (FD) methods are particularly easy to implement. Finite element methods are more flexible geometrically,...

APPM Department Colloquium - Elizabeth Bradley

Nov. 16, 2007

Event Description: Elizabeth Bradley, Department of Applied Mathematics, University of Colorado Boulder Dynamics of data assimilation Numerical solvers cannot track unmodelled effects like noise, and this becomes a particularly serious issue in complex nonlinear systems like fluid flows. One way to address this problem is to use observations of the...

APPM Department Colloquium - François G Meyer

Nov. 9, 2007

Event Description: François G Meyer, Department of Electrical and Computer Engineering, University of Colorado Boulder We can read your mind: the decoding of fMRI datasets Very recently, functional Magnetic Resonance Imaging (fMRI) has been used to infer subjective experience and brain states of subjects immersed in natural environments. These environments...

APPM Department Colloquium - Mike Wakin

Nov. 2, 2007

Event Description: Mike Wakin, Assistant Professor, University Michigan The Geometry of Compressed Sensing Compressed Sensing (CS) is a rapidly emerging field based on the revelation that signals obeying sparse models can be recovered from small numbers of nonadaptive (even random) linear measurements. In this talk I will survey some of...

APPM Department Colloquium - Randy Bank [CANCELLED]

Oct. 26, 2007

Event Description: Randy Bank, Professor of Mathematics, UCSD Convergence Analysis of a Domain Decomposition Paradigm We describe a domain decomposition algorithm for use in several variants of the parallel adaptive meshing paradigm of Bank and Holst. This algorithm has low communication, makes extensive use of existing sequential solvers, and exploits...

APPM Department Colloquium - Randall J. LeVeque

Oct. 26, 2007

Event Description: Randall J. LeVeque, Assistant Professor, University Michigan Shock Wave Propagation in Tissue and Bone Studying the physical and biological mechanisms of extracorporeal shock wave therapy (ESWT) requires modeling the propagation of strong shock waves through tissue and bone. Interfaces between different biological materials lead to reflections and focusing...

APPM Department Colloquium - John R. Cary

Oct. 19, 2007

Event Description: John R. Cary, Professor of Physics, University of Colorado Boulder, and CEO, Tech-X Corporation Self-consistent electromagnetic modeling with boundaries The difficulty in modeling electromagnetics is in choosing the correct algorithm from the plethora available. The choice ultimately depends on what is most critical for the problem to be...
