— A feature detection system has been developed for real-time identification of lines, circles and people legs from laser range data. A new method suitable for arc/circle detection is proposed: the Inscribed Angle Variance (IAV). Lines are detected using a recursive line fitting method. The people leg detection is based on geometrical relations. The system(More)
Identiÿcation results for the shaft-speed dynamics of an aircraft gas turbine, under normal operation , are presented. As it has been found that the dynamics vary with the operating point, non-linear models are employed. Two diierent approaches are considered: NARX models, and neural network models, namely multilayer perceptrons, radial basis function(More)
The problem of controlling a heating ventilating and air conditioning system in a single zone of a building is addressed. Its formulation is done in order to maintain acceptable thermal comfort for the occupants and to spend the least possible energy to achieve that. In most operating conditions these are conflicting goals, which require some sort of(More)
