Double-diffusive behaviour at high and low Prandtl number Pascale Garaud Department of Applied Mathematics and Statistics, University of California – Santa Cruz Date and time: Tuesday, April 5, 2011 - 4:30pm Abstract: Double-diffusive instabilities can occur in fluids which have a stable density stratification, but where the density depends on...

Parameterization of invariant manifolds for difference equations including discrete Lagrangians Hector Lomeli Department of Mathematics, Instituto Tecnológico Autónomo de México Date and time: Thursday, March 31, 2011 - 4:30pm Abstract: We generalize some notions that have played an important role in dynamics (namely invariant manifolds) to the more general context...

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...

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...

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...

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...

Robust and efficient algorithms for piecewise constant vector field topology Andrzej Szymczak Dept of Mathematical and Computer Science Date and time: Thursday, February 24, 2011 - 4:30pm Abstract: Development of robust methods of extracting stable features from datasets of various types is considered one of the fundamental problems in scientific...

Modeling Skeletal Muscle Mechanics: The Grand-Overview Oliver Röhrle Stuttgart Research Centre for Simulation Technology and Cluster of Excellence “Simulation Technology” (SimTech) Date and time: Tuesday, February 22, 2011 - 3:45pm Abstract: A skeletal muscle is a complex electro-mechanical system with inhomogeneous electrical and mechanical properties. Many different skeletal muscle models...

Subcritical percolation on networks Dane Taylor Applied Mathematics , University of Colorado Boulder Date and time: Thursday, February 17, 2011 - 4:30pm Abstract: Percolation on networks has applications ranging from epidemic and information spreading to system robustness. Extending previous results restricted to directed or Markovian networks, we introduce a general...

Using Traits-based Approaches to Understand the Dynamics of Biodiversity and Productivity Colleen Webb Dept of Biology, Colorado State University Date and time: Thursday, February 10, 2011 - 4:30pm Abstract: Predicting changes in community composition and ecosystem function in a rapidly changing world is a major research challenge in ecology and...
