Coupling the Finite Volume and Boundary Element Methods Christoph Erath NCAR Date and time: Tuesday, March 15, 2011 - 3:45pm Abstract: We develop a discretization scheme for the coupling of the finite volume method and the boundary element method in two dimensions, which describes, for example, the transport of a...

Dynamical Systems Seminar: Ashar Ali

March 10, 2011

A Chaotic Encryption Scheme Based on a 4-Dimensional Chaotic System Ashar Ali Applied Mathematics , University of Colorado Boulder Date and time: Thursday, March 10, 2011 - 4:30pm Abstract: Chaotic systems by definition exhibit sensitive dependence on initial conditions and have the capacity to display seemingly random behavior. Both of...

Dynamical Systems Seminar: Theodore Galanthay

March 3, 2011

Why ignoring your Darwinian fitness may be adaptive: Evolutionary dynamics of movement strategies in the presence of realistic constraints Theodore Galanthay Applied Mathematics , University of Colorado Boulder Date and time: Thursday, March 3, 2011 - 4:30pm Abstract: In most theoretical habitat selection models, modelers assume that organisms tend to...

Computational Math Seminar: Jose Garcia

March 1, 2011

High Order Method Modeling Environment (HOMME) Jose Garcia NCAR Date and time: Tuesday, March 1, 2011 - 3:45pm Abstract: The High Order Method Modeling Environment (HOMME) is a computational framework to solve the 3D most primitive equations of the global atmospheric circulation model. HOMME is one of the main dynamical...
