Model-based fault isolation and identification in hybrid systems is computationally expensive or even unfeasible for complex systems due to the presence of uncertainty concerning the actual state, and also due to the presence of both discrete and parametric faults coupled with changing modes in the system. In this work we improve fault isolation and identification performance for hybrid systems diagnosis...
Several techniques can be used to study electromagnetic propagation in tunnels. A combination of two of such techniques is presented in this paper to model propagation inside a rectangular tunnel. They are combined in order to maximize the benefits inherent to their theoretical principles and restrictions. Fields in the region close to the transmitter are obtained by means of spectral theory, whereas...
