    An analytical model for the approximate evaluation of the performance of priority schemes in the IEEE and SAE token bus protocols is developed. The model determines the average date latency of the four-level priority scheme in a token bus protocol. The priority scheme is analyzed in the framework of a single service system, where a station can transmit only one message each time it captures the to... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (368 KB)

    An overview is given of the experimental analysis of motion planning from comparison of two snapshots of the world: initial scene and goal scene. It is commonly believed that from comparison of these two images the researcher can deduce the plan of actions and, eventually, the program of motion (e.g. in robotics). Indeed, in many particular cases the existence of a knowledge inverse operator can b... View full abstract»
