The Silicon Strip Tracker (SST) is the intermediate part of the CMS Central Tracker System. SST is based on microstrip silicon devices and in combination with pixel detectors and the Microstrip Gas ...Chambers aims at performing pattern recognition, track reconstruction and momentum measurements for all tracks with

TeV at LHC. We aim at exploiting the advantages and the physics potential of the precise tracking performance provided by the microstrip silicon detectors on a large scale apparatus and in a much more difficult environment than ever. In this paper we describe the actual SST layout and the readout system.
The designs and implementations of two expert systems applicable to any railway station, the automatic train protection (ATP) design expert system (ADES), which automatically designs ATP systems, and ...the stationmaster assistant (SMA) which helps stationmasters choose safe routes, are discussed. These systems use shared knowledge to explicitly represent ATP systems and routes, making the systems easily understood, structured, and maintained. A knowledge-based approach enables the system to explain their decisions. The explanation module in ADES provides why and how facilities, both to simplify the maintenance and validation of the knowledge base and to train new experts on the ATP system functions. SMA operators can ask why a route was or was not feasible. When the stationmaster asks for currently feasible routes, the SMA presents the feasible routes, then the occupied routes, and then the unfeasible routes with explanations.< >
