Abstract. A paraconsistent logic is a logic which allows non-trivial inconsistent theories. One of the oldest and best known approaches to the problem of designing useful paraconsi...
In this paper, we propose a method for discovering hidden information from large-scale item set data based on the symmetry of items. Symmetry is a fundamental concept in the theory...
Schneider's work on rank functions [14] provides a formal approach to verification of certain properties of a security protocol. However, he illustrates the approach only wit...
Model-checking has turned out to be an efficient and relatively easy-to-use technique in the verification of formally described programs. However, there is one major drawback in u...
We develop a theory of bisimulation equivalence for the broadcast calculus CBS. Both the strong and weak versions of bisimulation congruence we study are justi ed in terms of a cha...
