Timed automata provide useful state machine based representations for the validation and verification of realtime control systems. This paper introduces an algorithmic methodolog...
A cover-automaton A of a finite language L is a finite automaton that accepts all words in L and possibly other words that are longer than any word in L. A minimal deterministic co...
In this paper we present query filtering techniques based on bottom-up tree automata for XML access control. In our authorization model (RXACL), RDF statements are used to represen...
Boolean programs with recursion are convenient abstractions of sequential imperative programs, and can be represented as recursive state machines (RSMs) or pushdown automata. Motiv...
We consider the problem of PAC-learning distributions over strings, represented by probabilistic deterministic finite automata (PDFAs). PDFAs are a probabilistic model for the gen...
