We develop a service that allows the current IEEE 802.11b MAC protocol to perform dynamic packet sizing and forward error correction. Our service, called ERSMAC, is designed to allow the deployment of the IEEE 802.11b protocol in industrial environments characterized by high BER and fast time variation. ERSMAC uses a maximum likelihood estimate of the BER(More)
C This paper provides a design outline and implementation procedure for a Secondary Energy Storage Unit (SESU) that can be used to meet the peak energy requirements of an electric vehicle during both acceleration and regenerative braking. The life cycle of the electric vehicle's batteries can be extended considerably by supplying peak energy requirements(More)
The general requirements for electrical equipment used in traction applications are reviewed. These requirements and conditions include high inertia load, smooth torque control over the full range, high reliability, low maintenance, high efficiency, low mass, extended weak-field range for the motors, high top speed, dynamic or regenerative braking, motor(More)
A method is presented which allows for the experimental determination of the characteristics of brushless PM synchronous machine parameters in the high speed operating range. The theory and real-time implementation is described for this computer based parameter identification method. Special computer assisted measuring techniques are conducted on a(More)
The principle of a novel prefetching strategy, horizontal demand prefetching, is presented. This mechanism allows deep prefetching without jump-related misses by prefetching shallowly across several independent streams in a horizontal fashion. Multistream processors using this technique can achieve very high memory utilization. The mechanism supports very(More)
