We analyze the safety question for the Non-Monotonic Transform NMT model, an access control model that encompasses a wide variety of practical access control mechanisms. In genera...
This paper describes a new algorithm of computing the convex hull of a 3-dimensional object. The convex hull generated by this algorithm stract polyhedron being described by a new ...
Abstract. In this article we present a conceptual analysis of the notion of learners’ selforganization in CSCL macro-scripts. We highlight that taking into account selforganizati...
We show that a combinatorial question which has been studied in connection with lower bounds for the knapsack problem by Brimkov and Dantchev (2001) is related to threshold graphs...
Quasi-set theory is a theory for dealing with collections of indistinguishable objects. In this paper we discuss some logical and philosophical questions involved with such a theo...
