A collaboration between three universities is working to create a battery that is capable of powering microelectromechanical systems (MEMS). The work is especially important because no viable battery currently exists for these tiny devices. The three-dimensional battery will be a departure from current battery designs, which stack "positive and negative electrodes... like sheets of paper." As more...

Scientists at the University of Notre Dame's Department of Electrical Engineering have developed "computer circuits that can be built to work without electricity -- a tiny initial charge is all that is needed." However, a major obstacle that needs to be overcome before the circuits can be useful is that they seem to work at temperatures just above absolute zero. This site is a news release from...

Despite being in existence for over a century, modern elevators have an underlying problem that is anything but easy to solve. When multiple elevators are being used in a single location, it quickly becomes a daunting task to create an intelligent control system that optimally meets the needs of its users. This paper, which will be presented at the 2003 Conference on Uncertainty in Artificial...
