Ambient intelligence (AmI) systems are smart interactive systems that perceive their surroundings using sensors and act upon them using actuators. One of the most common applications of such systems is Smart Homes. In this context, the ambient system can offer a great level of dependability if it is able to exploit available sensor data in order to autonomously perform diagnosis. However, ambient...
The performances of wind energy conversion systems (WECS) heavily depend on the accurate current sensing. A sudden failure in one of the current sensors decreases the system performances. Moreover, if a fault is not detected and handled quickly, its effect leads to system disconnection. Hence, to reduce the failure rate and to prevent unscheduled shutdown, a real-time fault detection, isolation, and...
In this paper we discuss the components and design of each part of an expert system for fault detection and diagnosis in the refrigeration process of a hydraulic power station. Given a minimum group of measurements, it is possible to extract behavior patterns for the whole system. The knowledge base is obtained by simulating the dynamic behavior of the process. The expert system was designed for a...
