INA S MUCH as none of the manifold attempts to define “a rare book” has yet obtained such unanimity of approval as to be reckoned entirely satisfactory or final, investigation into this question still remains fair game, is still in the public domain. The phrase-“a rare book”-can mean any one of three different things depending on the sense in which it is used. Two of these meaningsthose used in...

Reified logics have been a major subject of interest in the knowledge representation community for well over twenty years, since over the years, the need to quantify and reason about propositional entities such as events and states among other temporal entities has grown.

The rise in significance of cyber security has led to an increase in the range of interesting career paths that can be followed in this area. Inevitably there has also been an explosion in the diversity of available cyber security education, qualifications and training, most of which is targeted at those seeking to engage with this promising job market. In this article, some guidelines are prov...

In this paper, we consider minimization problems with a quasiconvex vector-valued inequality constraint. We propose two constraint qualifications, the closed cone constraint qualification for vector-valued quasiconvex programming (the VQ-CCCQ) and the basic constraint qualification for vector-valued quasiconvex programming (the VQ-BCQ). Based on previous results by Benoist, Borwein, and Popovic...
