LTL cannot express the whole class of ω-regular languages and several extensions have been proposed. Among them, Quantified propositional Linear Temporal Logic (QLTL), proposed b...
Abstract. We survey some of the main results regarding the complexity and expressive power of Live Sequence Charts (LSCs). We first describe the two main semantics given to LSCs: a...
Abstract. We present a general method to prove security properties of cryptographic protocols against active adversaries, when the messages exchanged by the honest parties are arbi...
Linguists seek to understand the semantics of expressions in human languages. Taking a computational point of view, there are many natural language expressions--operators in the w...
In the relational model it has been shown that the flat relational algebra has the same expressive power as the nested relational algebra, as far as queries over flat relations ...
