Robot soccer is an ambitious high-tech competition for universities, research institutes and industry. Several major tournaments are planned for 2008, the biggest of which is the 'RoboCup German Open'. From April 21-25, over 80 teams of scientists from more than 15 countries are expected to face off in Hall 25 at the Hannover Messe. In a series of soccer matches in several leagues, they will be putting the latest technologies on display. The tournament is being organized and carried out by the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS in Sankt Augustin.

For a machine, a soccer match is a highly complex endeavor. Robots must be able to reliably recognize the ball, the sidelines and the goalposts in addition to distinguishing between their teammates and opponents. To this end, they are outfitted with all sorts of high-tech equipment: cameras and sensors scan the robots' surroundings, internal processors convert data to define game tactics and defense strategies, and innovative engines allow the automated players to sprint across the field and unexpectedly fake out their opponents.

There are now nine leagues, each of which has its own technological focus. In the middle-size league, robots get around on wheels. Four players and a goalkeeper compete for each team on a 20 x 14-meter pitch with standard soccer goals. They must be able to function completely independently and are equipped with internal camera systems that process information in real time. What's more, the robots can move up to two meters per second.........

A modern computer contains two different types of components: magnetic components, which perform memory functions, and semiconductor components, which perform logic operations. A University of Missouri researcher, as part of a multi-university research team, is working to combine these two functions in a single hybrid material. This new material would allow seamless integration of memory and logical functions and is expected to permit the design of devices that operate at much higher speeds and use considerably less power than current electronic devices.

Giovanni Vignale, MU physics professor in the College of Arts and Science and expert in condensed matter physics, says the primary goal of the research team, funded by a $6.5 million grant from the Department of Defense, is to explore new ways to integrate magnetism and magnetic materials with emerging electronic materials such as organic semiconductors. The research may lead to considerably more compact and energy-efficient devices. The processing costs for these hybrid materials are projected to be much less than those of traditional semiconductor chips, resulting in devices that should be less expensive to produce.

In this approach, the coupling between magnetic and non-magnetic components would occur via a magnetic field or flow of electron spin, which is the fundamental property of an electron and is responsible for most magnetic phenomena, Vignale said. The hybrid devices that we target would allow seamless integration of memory and logical function, high-speed optical communication and switching, and new sensor capabilities.........

The National Science Foundation (NSF) has awarded a $65 million grant to the University of Tennessee, Knoxville (UTK) to develop Kraken, a state of the art supercomputer. Kraken will enhance the computational power of the TeraGrid, the world's largest, most powerful and comprehensive distributed cyberinfrastructure for open scientific research.

"Like the gargantuan sea monsters Kraken, which inspired the naming of this supercomputer, the possibilities in scientific and engineering advances it enables are enormous, limited only by the confines of human imagination and vision beyond the frontiers of science," said NSF Director Arden L. Bement in a taped message that was played today at a luncheon in Knoxville.

Tennessee Governor Phil Bredesen, UTK President John Petersen, Oak Ridge National Laboratory Director Thom Mason, and NSF's Office of Cyberinfrastructure Director Daniel Atkins attended the announcement ceremony.

"This $65 million NSF grant is not only the largest ever received by University of Tennessee, Knoxville; it is the largest research grant ever received by any university in the entire state of Tennessee," Bement said. "It enables an exciting new partnership between the National Science Foundation, the Department of Energy through its Oak Ridge National Laboratory, and the University of Tennessee and various partnering universities.".........
