The earlier work on predicate detection has assumed that the given computation is finite. Detecting violation of a liveness predicate requires that the predicate be evaluated on a...
Abstract. In the last few years, the semantics of Petri nets has been investigated in several different ways. Apart from the classical "token game", one can model the beh...
A Skolem sequence is a sequence s1, s2, . . . , s2n (where si A = {1 . . . n}), each si occurs exactly twice in the sequence and the two occurrences are exactly si positions apar...
This paper considers grasps and fixtures whose contacts react according to force-displacement laws consistent with friction constrains at the contacts. The passive force closure s...
We use a set of photographs showing similar scenes as a model for a single photograph this scene. A distance measure for this model is defined by correlating the neigborhoods of p...
