The states of a computing system bear information and change time, while its events bear time and change information. We develop a primitive algebraic model of this duality of tim...
: Watchdogs are a well-known and widespread means to increase the safety of microprocessors. The programmer or the compiler must insert instructions to reset the watchdog. If the p...
We present novel techniques for efficient controller synthesis for untimed and timed systems with respect to invariance and reachability properties. In the untimed case, we give al...
