Abstract. In this paper a semantic approach for the specification and the management of databases with evolving schemata is introduced. It is shown how a general object-oriented m...
We introduce a new approach to modeling uncertainty based on plausibility measures. This approach is easily seen to generalize other approaches to modeling uncertainty, such as pr...
The λ-calculus is considered an useful mathematical tool in the study of programming languages. However, if one uses βη-conversion to prove equivalence of programs, then a gros...
This paper outlines a formal model of the Intel IA-64 architecture, and explains how this model can be used to verify the correctness of assembly-level code optimizations. The form...
Abstract. In this paper we investigate how to model legal abrogation and annulment in Defeasible Logic. We examine some options that embed in this setting, and similar rule-based s...
