Involute spline couplings are used to transmit torque from a shaft to a hub or other rotating component. In theory, all teeth of the spline share the load equally. In practice, due to manufacturing variations, the teeth are unequally loaded. A new model for tooth engagement, based on statistics, predicts that the teeth engage in a sequence, determined by the individual clearances. As the shaft loa... View full abstract»

We study diagnosis of timed discrete-event systems (TDESs) modeled as timed-automata. Earlier works on diagnosis of TDESs assumed that a diagnoser has partial observation of events but can measure (or observe) time with arbitrary precision. In practice, however, time can only be measured with finite precision. We model the finite precision observability of time using a digital-clock that measures ... View full abstract»
