We present a parametric Hoare-like logic for computer-aided reasoning about typeable properties of functional programs. The logic is based on the concept of a specialised assertio...
We present a formal verification methodology that we have used on a computer system design project. The methodology integrates a temporal logic model checker with a conventional pr...
This paper describes the synthesis and hardware implementation of a signal-type asynchronous data communication mechanism (ACM). Such an ACM can be used in systems where a data-dr...
We describe the use of a flexible meta-interpreter for performing access control checks on deductive databases. The meta-program is implemented in Prolog and takes as input a datab...
