Visibly Pushdown Automata: From Language Equivalence to Simulation and Bisimulation
Abstract. We investigate the possibility of (bi)simulation-like preorder/equivalence checking on the class of visibly pushdown automata and its natural subclasses visibly BPA (Basi...

Queueing Analysis of Loss Systems with Variable Optical Delay Lines
—Recently, a new optical device called variable optical delay line (VODL) has been proposed in the literature. As suggested by its name, the delay of a VODL can be dynamically se...
