A concise object-oriented method for the development of real-time systems has been composed. Hardware components are modelled by (sofnuare) base objects; base objects are controll...

This paper is concerned with the design and performance of the telephone directory enquiry system newly adopted in Hong Kong. This system maintains three million telephone records...
We establish a decidability boundary of the model checking problem for infinite-state systems defined by Process Rewrite Systems (PRS) or weakly extended Process Rewrite Systems (w...
We present various techniques for improving the time and space efficiency of symbolic model checking for system requirements specified as synchronous finite state machines. We use...

Reachability and boundedness problems have been shown decidable for Vector Addition Systems with one zero-test. Surprisingly, place-boundedness remained open. We provide here a va...
