This paper describes a type system that is capable of expressing and enforcing immutability constraints. The speonstraint expressed is that the abstract state of the object to whi...
In this paper, partial knowledge about the possible transitions which can take place in a dynamical environment is represented by a set of pairs of propositional formulae, with th...
Abstract. Dealing with heterogeneous ontologies by means of semantic mappings has become an important area of research and a number of systems for discovering mappings between onto...
We describe a technique for automatically proving compiler optimizations sound, meaning that their transformations are always semantics-preserving. We first present a domainspeci...
We show that a wide class of bidirectional data-flow analyses and program optimizations based on them admit declarative descriptions in the form of type systems. The salient feat...
