From eardrums to electromagnetics, Demkowicz hears the problems
A good tool is both robust and accurate; it doesn’t break down easily, or give faulty readings or results. This standard applies to everything from a bathroom scale, or vending machine to a sniper rifle. It also rings true for computer code.
Industry and agencies use computer code to design products and test research in the digital realm. It cuts down and time and cost, and can allow a design to be tested in a variety of conditions. Teams of scientists and engineers at companies are dedicated to implementing codes that work efficiently and represent reality—codes that are robust and accurate. But sometimes, they get stuck.

Inderjit Dhillon and three Ph.D. students, Hsiang-Fu Yu, Cho-Jui Hsieh, and Si Si, won the Best Research Paper Award at the IEEE International Conference on Data Mining (ICDM'12). Their paper, "Scalable Coordinate Descent Approaches to Parallel Matrix Factorization for Recommender Systems," is available online. Selection was based on significance, originality, repeatability, and clarity. Award recipients present their paper at the conference Dec. 10-13, 2012 in Brussels.Posted: Nov. 28, 2012
The University of Texas at Austin and the Portugal International Collaboratory for Emerging Technologies (CoLab ) have signed a continuation agreement for their joint program of workshops, summer schools, faculty exchange programs, and postdoctoral fellowships with two ICES professors leading the effort. ICES Professors Irene M. Gamba will serve as director, and Luis Caffarelli as co-director for the project with approximately $830,000 in approved funding. Read more.Posted: Nov. 15, 2012
While all eyes were on the world’s top-ranked drivers Nov. 16-18 at the F1 Grand Prix race in Austin, long before the racing season started, engineers, aerodynamicists and computer scientists began preparing a strategy for their teams that increasingly leverages computational fluid dynamics or CFD. What is less well known to F1 fans is that CFD has advanced in sophistication in part because of the mathematical and theoretical work being done at ICES. While none of the ICES projects have been contracted specifically for F1 racing, one major area of study within CFD is turbulence, where Robert Moser, ICES deputy director and expert in turbulence modeling, is making scientific strides in understanding the physics of turbulence with his team at the $18.7 million research project known as PECOS.Read more.Posted: Nov. 15, 2012
Four ICES faculty were selected inaugural fellows of the American Mathematical Society: Todd Arbogast, William Beckner, Luis Caffarelli, and Irene Gamba.
The fellows, all professors of mathematics, were selected as members who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics.
“These four individuals are key members of the ICES core faculty and we are proud that they have been recognized by the AMS for their accomplishments," said ICES Director Tinsley Oden. Read more.Posted: Nov. 7, 2012
ICES Professor Bill Press has solved a complex game theory problem known as Prisoner's Dilemma. After toying with the problem for a while, ICES Professor William H. Press casually collaborated with Princeton University physicist Freeman J. Dyson and both found to their delight a new approach to the old problem. Their resulting paper appeared in the Proceedings of the National Academy of Sciences and became a top-10-most-downloaded paper of the journal for 4 months running. Read more.Posted: Nov. 6, 2012
