In this paper we define the notion of a compatibility relation so as to have a common framework for three nonmonotonic reasoning systems: normal logic programming, extended logic ...
Abstract. Current self-healing systems are built from “convergent” actions that only make repairs when necessary. Using an algebraic model of system administration, we challeng...
We study a notion of variation for real valued two variable functions called the path variation and we discuss its application as a low-level image segmentation method. For this pu...
We develop new proof techniques, based on non-interference, for the analysis of safety and liveness properties of cryptographic protocols expressed as terms of the process algebra ...
This paper examines challenges involved in managing product-centered communities. Using the notion of customer role ambiguity, the paper explores the ambiguity involved in balanci...
