Parity Automata for Quantitative Linear Time Logics

We initiate a study of automata-based model checking for previously proposed quantitative linear time logics interpreted over coalgebras. Our results include: (i) an automata-theoretic characterisation of the semantics of these logics, based on a notion of extent of a quantitative parity automaton, (ii) a study of the expressive power of Büchi variants of such automata, with implications on the...

Linear-Time Temporal Logic and Büchi Automata

Over the past two decades, temporal logic has become a very basic tool for specifying properties of reactive systems. For finite-state systems, it is possible to use techniques based on Büchi automata to verify if a system meets its specifications. This is done by synthesizing an automaton which generates all possible models of the given specification and then verifying if the given system refi...

Limited-Time Lookahead Diagnosability of Rectangular Hybrid Automata

This paper investigates the diagnosability of Rectangular Hybrid Automata used for modeling a class of hybrid systems. First, a generalized definition of Limited-Time Lookahead diagnosability of timed languages, for multiple failure modes, is proposed. Then, we provide a systematic approach, for checking the LTLa diagnosability of systems modeled with Rectangular Hybrid Automata, and verifying ...

Limited Automata and Unary Languages

Limited automata are one-tape Turing machines that are allowed to rewrite the content of any tape cell only in the first d visits, for a fixed constant d. When d = 1 these models characterize regular languages. An exponential gap between the size of limited automata accepting unary languages and the size of equivalent finite automata is proved. Since a similar gap was already known from unary c...
