Parametric regular path queries
Regular path queries are a way of declaratively expressing queries on graphs as regular-expression-like patterns that are matched against paths in the graph. There are two kinds o...

A Hierarchy of Constraint Systems for Data-Flow Analysis of Constraint Logic-Based Languages
Many interesting analyses for constraint logic-based languages are aimed at the detection of monotonic properties, that is to say, properties that are preserved as the computation...

Curvature Regularization for Curves and Surfaces in a Global Optimization Framework
Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we pr...

Fuzzy queries and relational databases
In this paper, the interest of fuzzy sets and possibility theory in the context of databases is presented. It is shown that these " notions provide an homogeneous framework f...

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...
