Unstructured mesh codes for modelling continuum physics phenomena have evolved to provide the facility to model complex interacting systems. Such codes have the potential to provide a high performance on parallel platforms for a small investment in programming. Single Program Multi Data (SPMD) domain decomposition techniques have been demonstrated to provide the required parameters of high para...

In this work, we develop a method of straight lines for solving a Bingham problem that models the flow of waxy crude oils. The model describes the flow of mineral oils with a high content of paraffin at temperatures below the cloud point (i.e. the crystallization temperature of paraffin) and more specifically below the pour point at which the crystals aggregate themselves and the oil takes a je...

• Since Wilkie’s result [9] (which established that the elementary theory Texp of (R, exp) is model complete and o-minimal), many o-minimal expansions of the reals have been investigated. The problem of constructing nonarchimedean models of Texp (and more generally, of an ominimal expansion of the reals) gained much interest. • In [2] it was shown that fields of generalized power series cannot ...

The Extraordinary Magnetoresistance (EMR) effect is a change in the resistance of a device upon the application of a magnetic field in hybrid structures, consisting of a semiconductor and a metal. The underlying principle of this phenomenon is a change of the current path in the hybrid structure upon application of a magnetic field, due to the Lorentz force. Specifically, the ratio of current, ...

The usual focus in authorship studies is on authorship attribution, i.e. determining which author (of a given set) wrote a piece of unknown provenance. The usual setting involves a small number of candidate authors, which means that the focus quickly revolves around a search for features that discriminate among the candidates. Whether the features that serve to discriminate among the authors ar...

Within the field of software maintenance, both reverse engineering and software reuse have been suggested as ways of salvaging some of the investment made in software that is now out of date. One goal that is shared by both reverse engineering and reuse is a desire to be able to redescribe source code, that is to produce higher level descriptions of existing code. The fundamental theme of this ...
