Clifford-Fischer theory applied to certain groups associated with symplectic, unitary and Thompson groups.
The character table of a finite group is a very powerful tool to study the groups and to prove many results. Any finite group is either simple or has a normal subgroup and hence will be of extension type. The classification ...
Analysis of mixed convection in an air filled square cavity.
A steady state two-dimensional mixed convection problem in an air filled square unit cavity has been numerically investigated. Two different cases of heating are investigated and compared. In the first case, the bottom ...
The application of multistate Markov models to HIV disease progression.
Survival analysis is a well developed area which explores time to single event analysis. In some cases, however, such methods may not adequately capture the disease process as the disease progression may involve ...
Analysis of shear-free spherically symmetric charged relativistic fluids.
We study the evolution of shear-free spherically symmetric charged fluids in general relativity. This requires the analysis of the coupled Einstein-Maxwell system of equations. Within this framework, the master field ...
Exact solutions for perfect fluids conformal to a Petrov type D spacetime.

RAT online : design, delivery and evaluation of constructivist computer supported martial arts learning environments.
This thesis describes the evaluation of several computer supported martial arts learning environments. These learning environments were designed, developed and implemented for practitioners of Rough and Tumble (RAT), a ...
Modelling longitudinal binary disease outcome data including the effect of covariates and extra variability.
The current work deals with modelling longitudinal or repeated non-Gaussian measurements for a respiratory disease. The analysis of longitudinal data for non-Gaussian binary disease outcome data can broadly be modeled ...
Qualitative and structural analysis of video sequences.
This thesis analyses videos in two distinct ways so as to improve both human understanding and the computer description of events that unfold in video sequences. Qualitative analysis can be used to understand a scene in ...
On the theory of the frobenius groups.
The Frobenius group is an example of a split extension. In this dissertation we study and describe the properties and structure of the group. We also describe the properties and structure of the kernel and complement, ...
Double-diffusive convection flow in porous media with cross-diffusion.
In this thesis we study double-diffusive convection and cross-diffusion effects in flow through porous media. Fluid flows in various flow geometries are investigated and the governing equations are solved analytically ...
