Minimal Models for Precipitating Convection Leslie Smith Department of Mathematics and Department of Engineering Physics, University of Wisconsin, Madison Date and time: Friday, October 12, 2012 - 3:30pm Abstract: Minimal models are formulated and explored for precipitating convection in a strongly stratified environment. The first model incorporates fast auto-conversion from...

Colloquium: Mahadevan Ganesh

Sept. 7, 2012

A Model Reduction Algorithm for Computational Electromagnetism Mahadevan Ganesh Department of Applied Mathematics & Statistics, Colorado School of Mines Date and time: Friday, September 7, 2012 - 3:30pm Abstract: We consider a parameterized multiple electromagnetic scattering wave propagation model in three dimensions. The parameters in the model describe the location,...

Non-Hydrostatic Modeling of General Ocean Circulation with First Order System Least Squares Finite Element Methods Jose Garcia NCAR - High Altitude Observatory Date and time: Tuesday, November 8, 2011 - 3:45pm Abstract: The dynamics of ocean circulation are generally well described by the Navier-Stokes equations in a rotational frame of...

Colloquium: Alireza Doostan

Oct. 25, 2011

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 - 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...
