Procedural function-based modelling of volumetric microstructures
We propose a new approach to modelling heterogeneous objects containing internal volumetric structures with size of details orders of magnitude smaller than the overall size of th...

Event-Clock Visibly Pushdown Automata
Abstract. We introduce the class of event-clock visibly pushdown automata (ECVPAs) as an extension of event-clock automata. The class of ECVPAs, on one hand, can model simple real-...

Randomized Self-Assembly for Exact Shapes
— Working in Winfree’s abstract tile assembly model, we show that a constant-size tile assembly system can be programmed through relative tile concentrations to build an n × n...
