Seminars

Colloids and Topological Defects in Liquid Crystals Ivan I. Smalyukh Department of Physics, CU Boulder Date and time: Friday, August 31, 2012 - 3:30pm Abstract: Liquid crystals and colloids find increasingly important applications in science and technology, ranging from information displays to direct probing of kinetic processes in crystals and...

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...

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...

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,...

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...

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...

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...

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...

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...

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...
