WUSTL computer engineers are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand.

In the world of small things, shape, order and orientation are surprisingly important, according to findings from a new study by chemists at Washington University in St. Louis. Lev Gelb, WUSTL associate professor of chemistry, his graduate student Brian Barnes, and postdoctoral researcher Daniel Siderius, used computer simulations to study a very simple model of molecules on surfaces, which looks a lot like the computer game “Tetris.” They have found that the shapes in this model (and in the game) do a number of surprising things.

Washington University and the Donald Danforth Plant Science Center have received two awards totaling $35 million from the U.S. Department of Energy (DOE) to do research on novel energy initiatives. At $20 million, the Washington University research award is the largest ever received on the Danforth Campus. The $15 million for the Donald Danforth Plant Science Center is the largest the organization has ever received.

William D. Richard, Ph.D., associate professor of computer science and engineering, and David Zar, research associate in computer science and engineering, have made commercial USB ultrasound probes compatible with Microsoft Windows mobile-based smartphones, thanks to a $100,000 grant Microsoft awarded the two in 2008.

William (Will) G. Donnelly, son of Terrence and Ruth Donnelly of St. Louis, Mo. (63139), recently was named the inaugural recipient of the Boeing/FIRST Scholarship at Washington University. A senior at Gateway Institute of Technology in St. Louis, Donnelly will enter the university’s School of Engineering & Applied Science as a freshman when the fall semester begins in August 2009.

Eight WUSTL faculty members will receive Outstanding St. Louis Scientist Awards from the Academy of Science of St. Louis.

AgarwalA mechanical engineer at Washington University in St. Louis is developing techniques that will lessen our monetary pain at the pump by reducing the drag of vehicles — planes, autos and trucks. Drag is an aerodynamic force that is the result of resistance a body encounters when it moves in a liquid or gaseous medium (such as air). Reduction in drag means less fuel would be required to overcome the fluid resistance encountered by the moving vehicle. Working with undergraduate and graduate students, Ramesh K. Agarwal, Ph.D, the William Palm Professor of Engineering at WUSTL, has successfully demonstrated that the drag of airplane wings and cars/trucks can be reduced by employing the active flow control technology.

Computer science faculty are exposing their undergraduate students to learning in ways that prepare them for interaction in the real work place. It’s not about “staying between the lines,” but more about getting out of your seat, moving around and interacting with your classmates. It’s called active learning, a learning-laboratory-based tutorial teaching concept.
