Expressiveness modulo Bisimilarity of Regular Expressions with Parallel Composition (Extended Abstract)

Jos C. M. Baeten, Bas Luttik, Tim Muller +1

The languages accepted by finite automata are precisely the languages denoted by regular expressions. In contrast, finite automata may exhibit behaviours that cannot be described b…

Density models for streamer discharges: beyond cylindrical symmetry and homogeneous media

Alejandro Luque, Ute Ebert

Streamer electrical discharges are often investigated with computer simulations of density models (also called drift-diffusion-reaction models). We review these models, detailing t…

The Influence of the Degree of Heterogeneity on the Elastic Properties of Random Sphere Packings

Iwan Schenker, Frank T. Filser, Markus Hütter +1

The macroscopic mechanical properties of colloidal particle gels strongly depend on the local arrangement of the powder particles. Experiments have shown that more heterogeneous mi…

Folk Theorems on the Correspondence between State-Based and Event-Based Systems

M. A. Reniers, T. A. C. Willemse

Kripke Structures and Labelled Transition Systems are the two most prominent semantic models used in concurrency theory. Both models are commonly believed to be equi-expressive. On…
