In this paper we report on a novel approach for uniform encoding of hash functions (but also other cryptographic functions) into propositional logic formulae, and reducing cryptanalysis problems to the satisfiability problem. The approach is general, elegant, and does not require any human expertise on the construction of a specific cryptographic function. By using this approach, we developed a...

As medical data has increased in volume the physician has had difficulty in using the data effectively. One explanation seems to be that the large volume of data makes it a formidable task for the physician to remember the interrelationships among signs, symptoms, and laboratory tests for a wide variety of diseases. Thus, it seems that studies need to be undertaken which will attempt to analyze...

In the context of the abstract interpretation theory, we study the relations among various abstract domains for groundness analysis of logic programs. We reconstruct the well-known domain Pos as a logical domain in a fully automatic way and we prove that it is the best abstract domain which can be set up from the property of groundness by applying logic operators only. We propose a new notion o...

Statements of degree appear to falsify basic doctrines in Tractatus Logico-Philosophicus. I offer a fresh formulation the challenge and assess solution proposed on Wittgenstein’s behalf by Sarah Moss. find that Moss’s proposal fails. The rides part novel interpretations pronouncements Wittgenstein nature elementary proposition. cannot be sustained but textual case hints at important overlooked ...
