Wireless networks today are able to brake just one bike, but in the future, they could regulate entire trains. Computer scientists at Saarland University in Germany are designing mathematical calculations to check such systems automatically. Professor Holger Hermanns, whose group developed the...

Finite element modeling and analysis Dynamic Concepts Huntsville, AL 256-922-9888 www.dynamic-concepts.com NASA tasked Dynamic Concepts (DCI) with assessing the structural dynamics of the rollout process, whereby the space shuttle orbiter, external tank, and solid rocket booster...

Georgia Tech researchers have developed a new protoype engine that uses up to 40% less fuel by running on solar power while in space and by fine-tuning exhaust velocity. The key to the engine improvements is the ability to optimize the use of available power. A traditional chemical rocket engine (attached to a satellite ready...

As petroleum prices spiral higher, new technologies are being developed to help keep prices down. The balanced flow meter, technology originally developed by NASA for the space shuttle, promises to ease pain at the pump by being more precise and consuming less...

A paper suggests the development of a hybrid rocket engine and associated equipment for returning a sample of material from Mars at relatively low cost. In a hybrid rocket engine, a solid fuel is burned by use of a liquid or gaseous oxidizer, the flow of which can be throttled to control...
