A Calculus for Causal Relevance
We present a sound and complete calculus for causal relevance that uses Pearl's functional causal models as semantics. The calculus consists of axioms and rules of inference ...

Unifying Theories of Objects
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...

A Refinement Calculus for the Development of Real-Time Systems
We present a calculus which can transfer specifications to objects for the development of real-time systems. The object model is based on a practical OO development technique--HRT...

Linearly-Used State in Models of Call-by-Value
Abstract. We investigate the phenomenon that every monad is a linear state monad. We do this by studying a fully-complete state-passing translation from an impure call-by-value lan...

From Images to Bodies: Modelling and Exploiting Spatial Occlusion and Motion Parallax
This paper describes the Region Occlusion Calculus (ROC-20), that can be used to model spatial occlusion and the effects of motion parallax of arbitrary shaped objects. ROC-20 ass...
