On Construction of Holistic Synopses under the Duplicate Semantics of Streaming Queries
Transaction-time temporal databases and query languages provide a solid framework for analyzing properties of queries over data streams. In this paper we focus on issues connected...

A Symbolic Decision Procedure for Robust Safety of Timed Systems
We present a symbolic algorithm for deciding safety (reachability) of timed systems modelled as Timed Automata (TA), under the notion of robustness w.r.t. infinitesimal clock-drif...

Towards a Science of Temporal Databases
Computer science has long been considered to emphasize three distinct perspectives: mathematics, science, and engineering. While the database field has some very strong mathemati...

Temporal Relations of Intervals with a Gap
Forty-four relations are found between an interval and an interval with a gap ( rIIg ), capturing semantics that are distinct from those of the sets of constituting intervals and ...

Automated Natural Deduction for Propositional Linear-Time Temporal Logic
We present a proof searching technique for the natural deduction calculus for the propositional linear-time temporal logic and prove its correctness. This opens the prospect to ap...

Temporalising Tractable Description Logics
It is known that for temporal languages, such as firstorder LT L, reasoning about constant (time-independent) relations is almost always undecidable. This applies to temporal des...
