Verification of qualitative Z constraints
We introduce an LTL-like logic with atomic formulae built over a constraint language interpreting variables in Z. The constraint language includes periodicity constraints, comparis...

Optic-Flow Information Extraction with Directional Gaussian-Derivatives
This work is intended to give some ideas to extract motion information from an image sequence. A directional energy is defined in terms of the 1-D Hermite transform coefficients o...

Reachability Analysis of Pushdown Automata: Application to Model-Checking
We apply the symbolic analysis principle to pushdown systems. We represent (possibly in nite) sets of con gurations of such systems by means of nite-state automata. In order to re...

Verifying Properties of (Timed) Event Driven Process Chains by Transformation to Hybrid Automata
Abstract: Event-driven Process Chains (EPCs) are a commonly used modelling technique for design and documentation of business processes. Although EPCs have an easy-to-understand no...

Combining Influence Maps and Cellular Automata for Reactive Game Agents
Agents make up an important part of game worlds, ranging from the characters and monsters that live in the world to the armies that the player controls. Despite their importance, a...
