Blood vessel simulation probes secrets of brainApril 13, 2011

Zoom down to one artery in your body, and the commotion is constant: blood cells hurtle down the passage with hundreds of their kin, bumping against other cells and the walls as they go. The many variables—and the sheer immensity of the human circulatory system—have kept scientists from closely documenting the rough-and-tumble life inside blood vessels.

Argonne researcher Misun Min recognized for top paperApril 1, 2011

A paper by Argonne assistant computer scientist Misun Min and her collaborator Taehun Lee at the City College of City University of New York has been recognized as one of the "Top 25 Hottest Articles" in the Journal of Computational Physics from October to December 2010. The paper, titled "A spectral-element discontinuous Galerkin lattice Boltzmann method for nearly incompressible flow," presents a new method that involves decoupling the numerical scheme into collision and streaming steps.

New computational framework for estimating wind power uncertaintyFebruary 1, 2011

Researchers in the Mathematics and Computer Science Division at Argonne, together with two doctoral students, have developed a computational framework that integrates a state-of-the-art weather forecasting model with stochastic unit commitment (UC) and energy dispatch (ED) formulations. Both UC and ED operation—which represent which power generating units to run at what levels for the most economic operation—are critical because of their strong economic impact and increasing emissions concerns.
