Linear time membership in a class of regular expressions with interleaving and counting
The extension of Regular Expressions (REs) with an interleaving (shuffle) operator has been proposed in many occasions, since it would be crucial to deal with unordered data. Howe...

Error Mining for Regular Expression Patterns
In the design of type systems for XML programming languages based on regular expression types and patterns the focus has been over result analysis, with the main aim of statically ...

Towards a Multi-calendar Temporal Type System for (Semantic) Web Query Languages
Abstract. Time is omnipresent on the (Semantic) Web. However, formalism like XML, XML Schema, RDF, OWL and (Semantic) Web query languages have, if any, only very limited notions of...

Period-Dependent Initial Values for Exact Schedulability Test of Rate Monotonic Systems
Real-time systems using Rate Monotonic fixed priority scheduling can be checked for schedulability either by pessimistic schedulability conditions or exact testing. Exact testing ...

Probabilistic Checking of Proofs; A New Characterization of NP
We give a new characterization of NP: the class NP contains exactly those languages L for which membership proofs (a proof that an input x is in L) can be verified probabilisticall...
