Event Description: Luis Chacon, Los Alamos National Laboratory On fully implicit methods for extended magnetohydrodynamics Magnetohydrodynamics (MHD) describes the behavior of charged hot gases (plasmas) in the presence of electromagnetic fields, and is a crucial tool for the understanding of solar, space, and laboratory (e.g. thermonuclear fusion) plasmas. Mathematically, MHD...

Event Description: Robert Krasny, Professor, University of Michigan Lagrangian Simulations of Fluids and Plasmas This talk will describe recent work on lagrangian simulations of fluids and plasmas. The basic idea is to replace the standard Eulerian formulation by a Lagrangian formulation in which the flow map is the key unknown...

Event Description: Travis Austin, Tech-X Corporation Discontinuous Cardiac Activation Modeling using Fast Multilevel Solvers The ventricles are the core pumping chambers of the heart, responsible for pumping deoxygenated blood from the heart to the lungs and oxygenated blood from the heart to the rest of the body. Both left and...

Event Description: Joseph F. Grcar, Center for Computational Science and Engineering, Lawrence Berkeley National Laboratory John von Neumann and the Origins of Scientific Computing Scientific computing as we understand it today began to be practiced around the time of Carl Friedrich Gauss in the form of astronomical calculations based on...

Event Description: Juan G. Restrepo, Postdoc with Alain Karma at the Center for Interdisciplinary Research on Complex Systems, Northeastern University Dynamics on complex networks: synchronization, percolation, and the dynamical importance of nodes and links. There has been much recent interest in studying dynamical processes on networks due to the realization...

Event Description: Cleve Moler, Author of MATLAB and Founder of MathWorks Evolution of MATLAB We show how MATLAB has evolved over the last 25 years from a simple matrix calculator to a powerful technical computing environment. We demonstrate several examples of MATLAB applications. We conclude with a few comments about...

Event Description: Bob Eisenberg, Department of Molecular Biophysics & Physiology, Rush University Medical Center Ion Channels: Devices for Atomic Control of Molecular Transport Protein channels conduct ions through a narrow tunnel of fixed charge and act as gatekeepers for cells and cell compartments. Hundreds of types of channels are studied...

Event Description: Dongbin Xiu, Department of Earth And Atmospheric Sciences, Purdue University Efficient methods for numerical simulations with uncertainty Most of the research efforts in scientific computing so far have been in developing efficient algorithms for different applications, assuming ideal inputs with precisely defined computational domains. Recently, there has been...

Event Description: Webster Cash, Department of Astrophysical and Planetary Scienes (APS), University of Colorado Boulder Struggling with the mathematics of diffraction and the search for life in the universe Our best hope of finding evidence of life in the Universe is to study the Earth-like planets around nearby stars. Spectra...

Event Description: Natasha Flyer, Institute for Mathematics Applied to Geosciences (IMAGe), NCAR Modeling simple atmospheric flows on the sphere using radial basis functions Since the early 1990s, radial basis functions (RBFs) have been applied to solve simple elliptical and mixed parabolic partial differential equations (PDEs). Not until 2003 was the...
