Abstract. We present a Hoare logic for a simple imperative whilelanguage with stored commands, ie. stored parameterless procedures. Stores that may contain procedures are called hi...
An exact Markov chain model of the B-cell algorithm (BCA) is constructed via a novel possible transit method. The model is used to formulate a proof that the BCA is convergent abso...
Abstract. Non-interference is a desirable property of systems in a multilevel security architecture, stating that confidential information is not disclosed in public output. The c...

The binary algorithm is a variant of the Euclidean algorithm that performs well in practice. We present a quasi-linear time recursive algorithm that computes the greatest common di...
We present a modular approach to defining logics for a wide variety of state-based systems. We use coalgebras to model the behaviour of systems, and modal logics to specify behavi...
