Today many formalisms exist for specifying complex Markov chains. In contrast, formalism for specifying the quantitative properties to analyze have remained quite primitive. In th...
We present a new formalization of the algebraic hierarchy in Coq, exploiting its new type class mechanism to make practical a solution formerly thought infeasible. Our approach add...
Abstract Subtyping relations for object-oriented formalisms describe relationships between super- and subclasses which satisfy the substitutability requirement imposed on types and...
Many papers have been written on the structural aspect of view mechanisms for object-oriented databases. A clean model that focuses speci cally on the interplay between methods an...
We describe a language which can be used to model business processes (both technical and nontechnical). It has a formal semantics, so as to enable formal analysis and prediction o...
