We propose a two-pha.se algorithm for physical database design. In phase one the algorithm, for each logical query, losesrules to determine characteristics of a physical design (s...
Due to the significant development of network services in the past few years, their validation has become increasingly difficult. The advent of novel approaches to the issue of val...
Spacecraft are key components of military operations and everyday life. To achieve space situation awareness, human operators must monitor large numbers of parameters. During off-...
Abstract. We presents a compositional Hoare logic for proving semantic security of modes of operation for symmetric key block ciphers. We propose a simple programming language to s...
Interactive theorem provers require too much effort from their users. We have been developing a system in which Isabelle users obtain automatic support from automatic theorem prov...
