Seminars

Computational Math Seminar 11/15/11 Ashar Ali Applied Mathematics , University of Colorado Boulder Date and time: Tuesday, November 15, 2011 - 3:30pm Abstract: t has been widely established that radial diffusion is responsible for populating and depleting the radiation belts surrounding the Earth with high energy charged particles. Initially it...

Weighted Least-Square Finite Element Methods for PIV Data Assimilation Jeff Heys Dept. of Chemical and Biological Engineering, Univ of Montana Date and time: Monday, November 14, 2011 - 3:45pm Abstract: The ability to determine and diagnose irregular flow patterns clinically in the left ventricle (LV) is currently very challenging. One...

Anisotropy in rapidly rotating helical flows Amrik Sen Applied Mathematics , University of Colorado Boulder Date and time: Thursday, November 10, 2011 - 4:00pm Abstract: Rapidly rotating fluid flow is characterized by the emergence of columnar structures that are representative of quasi-two dimensional behavior of the flow. It is known...

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...

Evaluating and Improving Models of Protein Interaction Network Evolution Debra Goldberg Department of Computer Science, University of Colorado Boulder Date and time: Thursday, November 3, 2011 - 4:00pm Abstract: Theoretical models of protein interaction networks (PINs) are valuable tools in evolutionary inference. Theoretical models based on gene duplication and divergence...

Relative equilibria in the four vortex problem with two pairs of equal vorticities Manuele Santoprete Department of Mathematics, Wilfrid Laurier University Date and time: Thursday, October 27, 2011 - 4:00pm Abstract: The N-vortex problem concerns the dynamics of N point vortices moving in the plane. Of particular interest in this...

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...

Macroscopic description of spatially coupled oscillators with finite response times Juan Restrepo Applied Mathematics , University of Colorado Boulder Date and time: Thursday, October 20, 2011 - 4:00pm Abstract: Synchronization in coupled oscillator systems is a paradigmatic example of collective emerging behavior from many simple interacting units. In various applications,...

Network connectivity during mergers and growth: Optimizing the addition of a module Dane Taylor Applied Mathematics , University of Colorado Boulder Date and time: Thursday, October 13, 2011 - 4:00pm Abstract: The principal eigenvalue λ of a network’s adjacency matrix often determines dynamics on the network (e.g., in synchronization and...

A Goal-Oriented Approach to Least-Squares Finite Element Methods Jehanzeb Hameed Chaudhry Department of Mathematics, Colorado State University Date and time: Tuesday, October 11, 2011 - 3:45pm Abstract: In this talk we introduce an approach that augments least-squares finite element formulations with user-specified goals or quantities-of-interest. The method incorporates the quantity-of-interest...
