Real Time Language Recognition on 2D Cellular Automata: Dealing with Non-convex Neighborhoods
In this paper we study language recognition by two-dimensional cellular automata on different possible neighborhoods. Since it is known that all complete neighborhoods are linearl...

Modeling Long-Running Transactions with Communicating Hierarchical Timed Automata
Long-Running transactions consist of tasks which may be executed sequentially and in parallel, may contain sub-tasks, and may require to be completed before a deadline. These trans...

Finite Automata as Time-Inv Linear Systems Observability, Reachability and More
We show that regarding finite automata (FA) as discrete, time-invariant linear systems over semimodules, allows to: (1) express FA minimization and FA determinization as particula...

Cellular Automata: Real-Time Equivalence Between One-Dimensional Neighborhoods
Abstract. It is well known that one-dimensional cellular automata working on the usual neighborhood are Turing complete, and many acceleration theorems are known. However very litt...

On Recognizable Timed Languages
In this work we generalize the fundamental notion of recognizability from untimed to timed languages. The essence of our definition is the existence of a right-morphism from the m...
