This paper presents a proactive maintenance scheme for fault detection, diagnosis and prediction in electrical valves. The proposed scheme is validated with a case study, considering a specific valve used for controlling the oil flow in a distribution network. The scheme is based in self-organizing maps, which perform fault detection and diagnosis, and(More)
This paper presents a proactive maintenance scheme for the detection and diagnosis of faults in electrical valves. In our case study, these actuators are used for controlling the flow in an oil distribution network. An embedded system implements selforganizing maps for the detection and classification of faults that lead to deviations either on torque, or(More)
The city of New York is served by the largest and busiest airport complex in the world. The three metropolitan airports, LaGuardia (LGA), Newark Liberty International (EWR), and John F. Kennedy International (JFK), are consequently plagued by flight delays. Since population density and economic feasibility prohibit further development of New York City(More)
Attention has recently been drawn to the issue of transboundary invasions, where species introduced and naturalized in one country cross international borders and become problematic in neighbouring countries. Robust modelling frameworks, able to identify the environmental drivers of invasion and forecast the current and future potential distribution of(More)
