The development of expert systems using parallel machines is a practice in its infancy, but its future is very promising. Researchers at the Artificial Intelligence Laboratory of the C.M.R. de Saint-Jean have been able to implement a cooperative system in which relatively independent agents cooperate to solve a specific problem. The system presented is implemented on a distributed memory parall...

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
