Bisimulation of Dynamical Systems
A general notion of bisimulation is studied for dynamical systems. An algebraic characterization of bisimulation together with an algorithm for computing the maximal bisimulation r...

A Priorean Approach to Time Ontologies
Any non-trivial top-level ontology should take temporal notions into account. The details of how this should be done, however, are frequently debated. In this paper it is argued th...

Modularity in DL-Lite
We develop a formal framework for modular ontologies by analysing four notions of conservative extensions and their applications in refining, re-using, merging, and segmenting ont...

A material focus: exploring properties of computational composites
In this paper we build on the notion of computational composites, which hold a material perspective on computational technology. We argue that a focus on the material aspects of t...
