Accelerating Scientific Discovery through Computation and Visualization II

May 1, 2002
Author(s)
James S. Sims, William L. George, Steven G. Satterfield, Howard Hung, John G. Hagedorn, Peter M. Ketcham, Terence J. Griffin
This is the second in a series of articles describing a wide variety of projects at NIST that synergistically combine physical science and information science. It describes, through examples, how the Scientific Applications and Visualization Group (SAVG)

Parallel Calculation of Electron Multiple Scattering Using Lanczos Algorithms

March 1, 2002
Author(s)
Charles E. Bouldin, A L. Ankudinov, J J. Rehr, James S. Sims, Howard Hung
Real space multiple scattering calculations of the elctronic density of states and x-ray spectra in solids typically scale as the cube of the system and basis set size, and hence are highly demanding computationally. For example, calculations near the Si K

Accelerating Scientific Discovery through Computation and Visualization

November 1, 2000
Author(s)
James S. Sims, John G. Hagedorn, Peter M. Ketcham, Steven G. Satterfield, Terence J. Griffin, William L. George, H A. Fowler, B A. am Ende, Howard Hung, Robert B. Bohn, John E. Koontz, Nicos Martys, Charles E. Bouldin, James A. Warren, D L. Feder, Charles W. Clark, Bernard J. Filla, Judith E. Terrill
The rate of scientific discovery can be accelerated through computation and visualization. This acceleration results from the synergy of expertise, computing tools, and hardware for enabling high performance computation, information science, and

Boussinesq Algorithm for Enclosed Buoyant Convection in Two Dimensions.

March 1, 1991
Author(s)
Ronald G. Rehm, Hai C. Tang, Howard R. Baum, James S. Sims, Daniel M. Corley
Approximate equations for a Boussinesq model with viscous dissipation and thermal conduction describing buoyant convection driven by a heat source in rectangular enclosure are derived. The finite-difference algorithm for computing transient solutions in
