Investigation of a Web-based expert system shell

Abstract: The identification of objects has always been of importance to people, whether it be the identification of foodstuffs, poisonous plants, illnesses or the reason that a computer is malfunctioning. People are able to make these identifications based on knowledge gained from education and experience. Amazingly enough, people are able to make identifications even though no two objects are exactly alike (inexact knowledge) and even if they do not have all the information about an object available (incomplete knowledge).

Integral equations for elliptic problems with edge singularities and applications to the fourier-boundary element method

Abstract: -Let u(x 1,x 2 Z) = be the tangentially regular solution of a transmission problem for the Laplace operator in the horizontal strip × (0,π), the interface being lateral faces of a right prism of height π. We show that each Fourier coefficient ul (x 1,x 2) is the single-layer potential Vl (x 1,x 2 ql ) relative to the two-dimensional Helmholtz operator −δ + l 1. The density ql solves a boundary integral equation, which is uniformly (with respect to the parameter l) well-posed in suitable Sobolev spaces. Decomposition of ql into regular part and singular functions is investigated and used to design an optimally convergent discrete solution ql, h of a boundary element method (BEM) the mesh size of which is explicitly graded and adapted. On the other hand, global regularity of ql in suitable weighted Sobolev spaces is established. This is used to implement a more general optimally convergent BEM with solution ql, h and with mesh size refined only near the corners of the interface. The truncated Fourier series...

Should prisoners have a right to vote

Abstract: This article raises a number of issues, such as voting rights in general and the extent that government should go to ensure that all are able to exercise this right in a democracy. Also raised is the issue of prisoners' rights. Finally, the peculiarities of the South African prison system are at issue here too. The article will examine prisoners' voting rights in general elections. Provincial and local government elections are somewhat different and will not be discussed.

Minotaur lost: The labyrinthine nature of time in postmodern fiction∗

Abstract: Summary The article uses the conclusions reached by contemporary science to investigate the postmodern renaissance of the labyrinth. The first part concentrates on spatial labyrinths in the fiction of Umberto Eco and Jorge Luis Borges, as these are precursors of temporal labyrinths, and shows how Newton's laws, which prove the relativity of space, can be used to explain these labyrinths. The second part of the article examines temporal labyrinths in Borges's and Peter Ackroyd's work. Einstein's theory of relativity as well as recent developments in new physics, is used to provide a possible explanation of these labyrinths of temporal relativity. The article shows that the obfuscation and comprehension of both spatial and temporal labyrinths depend on the distinction between inside and outside: inside the labyrinth, there is confusion; outside the labyrinth, the structure can be comprehended. The parallel development in literature and science, in their acknowledgement of the relativity of space and time, b...
