This paper introduces an extension of linear temporal logic that allows to express properties about systems that are composed of entities (like objects) that can refer to each othe...
We present a modelling method and graphical user interface for the creation of natural branching structures such as plants. Structural and geometric information is encapsulated in...
Abstract. In this paper we study dualities of graphs and, more generally, relational structures with respect to full homomorphisms, that is, mappings that are both edge- and non-ed...
Searching for similar objects in metric-space databases can be efficiently solved by using index data structures. A number of alternative sequential indexes have been proposed in...
We investigate the application of a logic-based framework representing an agent environment as a composite structure that evolves over time. Such a complex structure contains the i...
