Protocol conversion involves the use of a converter to control communication between two or more protocols such that desired system-level specifications can be satisfied. We invest...
The pebble tree automaton and the pebble tree transducer are enhanced by additionally allowing an unbounded number of `invisible' pebbles (as opposed to the usual `visible...

We introduce discrete pushdown timed automata that are timed automata with integer-valued clocks augmented with a pushdown stack. A con guration of a discrete pushdown timed automa...

Of special interest in formal verification are safety properties, which assert that the system always stays within some allowed region. A computation that violates a general linea...
Abstract. The relationship between automata and logics has been investigated since the 1960s. In particular, it was shown how to determine, given an automaton, whether or not it is...
