In this paper, we aim to ascribe a meaning to SysML activity diagrams. To this end, we propose a dedicated algebraic-like language, namely activity calculus, and an operational se...
We present an approach to modelling Abadi–Cardelli-style object calculi as Unifying Theories of Programming (UTP) designs. Here we provide a core object calculus with an operatio...
In this paper, we propose a simple and flexible execution model that (i) supports a wide spectrum of alternative optimization and execution strategies and their mixtures, (ii) pro...

Feature structures are informational elements that have been used in several linguistic theories and in computational systems for natural-language processing. A logicaJ calculus h...
We obtain a new formalism for concurrent object-oriented languages by extending Abadi and Cardelli's imperative object calculus with operators for concurrency from the -calc...
