Real-Time Language Recognition by Alternating Cellular Automata
The capabilities of alternating cellular automata (ACA) to accept formal languages are investigated. Several notions of alternation in cellular automata have been proposed. Here we...

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...

Dealing with practical limitations of distributed timed model checking for timed automata
Two base algorithms are known for reachability verification over timed automata. They are called forward and backwards, and traverse the automata edges using either successors or p...

On the Supports of Recognizable Timed Series
Recently, the model of weighted timed automata has gained interest within the real-time community. In a previous work, we built a bridge to the theory of weighted automata and intr...

Specification and Analysis of Soft Real-Time Systems: Quantity and Quality
This paper presents a process algebra for specifying soft real-time constraints in a compositional way. For these soft constraints we take a stochastic point of view and allow arb...
