Remediation of first-year mathematics students' algebra difficulties.
The pass rate of first-year university mathematics students at the University of KwaZulu-Natal (Pietermaritzburg Campus) has been low for many years. One cause may be weak algebra skills. At the time of this study, revision ...
Cluster mass reconstruction via gravitational lensing.
The presence of massive objects is detectable in observations via the gravitational lensing effect on light from more distant sources. From this effect it is possible to reconstruct the masses of clusters, and the distribution ...
Real options : duopoly dynamics with more than one source of randomness.
The valuation of real options has been of interest for some time. Recently, the model has been revised to include more than one source of randomness, e.g. Paxson and Pinto (2005). In this dissertation, we present a model ...
The effects of using visual literacy and visualization in the teaching and learning of mathematics problem solving on grade 6 and grade 7.
In this study I examine the effects of visualization in the teaching of problem solving in grades 6 and 7 in a school south of Durban in KwaZulu Natal. One of the goals of mathematics instruction according to the Department ...
New analytical stellar models in general relativity.
We present new exact solutions to the Einstein and Einstein-Maxwell field equations that model the interior of neutral, charged and radiating stars. Several new classes of solutions in static spherically symmetric interior ...
Multi-parameter perturbation analysis of a second grade fluid flow past an oscillating infinite plate.
In this dissertation we consider the two dimensional flow of an incompressible and electrically conducting second grade fluid past a vertical porous plate with constant suction. The flow is permeated by a uniform transverse ...
