Formal verification of multitasking applications based on timed automata model
The aim of this paper is to show, how a multitasking application running under a real-time operating system compliant with an OSEK/VDX standard can be modeled by timed automata. Th...

Symmetry Coincides with Nondeterminism for Time-Bounded Auxiliary Pushdown Automata
—We show that every language accepted by a nondeterministic auxiliary pushdown automaton in polynomial time (that is, every language in SAC1 = Log(CFL)) can be accepted by a symm...

On the minimization of XML Schemas and tree automata for unranked trees
Automata for unranked trees form a foundation for XML schemas, querying and pattern languages. We study the problem of efficiently minimizing such automata. First, we study unrank...

On the efficient construction of quasi-reversible automata for reversible languages
Quasi-reversible automata is a suitable representation for reversible languages. In this work a method is proposed to obtain such an automaton for any given reversible language re...

Timed-Arc Petri Nets vs. Networks of Timed Automata
Abstract. We establish mutual translations between the classes of 1safe timed-arc Petri nets (and its extension with testing arcs) and networks of timed automata (and its subclass ...
