This paper introduces process spaces, a unified theory of interacting systems. The trait, abstract executions, leads to a simple and general set formalism. For concurrent systems ...
The event calculus is a logic programming formalism for representing events and their effects especially in database applications. This paper presents the use of the event calculus...
We show how the features of modern integrated functional logic programming languages can be exploited to implement graphical user interfaces (GUIs) in a high-level declarative styl...
Erlang is a concurrent functional programming language designed to ease the development of large-scale distributed soft real-time control applications. It has so far been quite su...
