Object classification is a fundamental step in automatic video-surveillance that allows improved tracking and a more accurate description of events. However, as real-world applications need a real-time, flexible, easy and quick to configure solution, the design of a practical object classification algorithm becomes a challenge. This paper analyses advantages and disadvantages of different frame...

The acid-mediation hypothesis, that is, the hypothesis that acid produced by tumours, as a result of aerobic glycolysis, provides a mechanism for invasion, has so far been considered as a relatively closed system. The focus has mainly been on the dynamics of the tumour, normaltissue, acid and possibly some other bodily components, without considering the effect of an external intervention such ...

The concept of a pre-open set in a topological space was introduced by H. H. Corson and E. Michael in 1964 [3]. A subset A of a topological space (X, τ) is called pre-open or locally dense or nearly open if A ⊆ Int(Cl(A)). A set A is called pre-closed if its complement is preopen or equivalently if Cl(Int(A)) ⊆ A. The term, pre-open, was used for the first time by A. S. Mashhour, M. E. Abd El-M...
