End-to-end single-rate multicast congestion detection using support vector machines
(2008)
IP multicast is an efficient mechanism for simultaneously transmitting bulk data to multiple receivers. Many applications can benefit from multicast, such as audio and videoconferencing, multi-player games, multimedia ...
Comparing South African financial markets behaviour to the geometric Brownian Motion Process
(University of the Western Cape, 2008)
This study examines the behaviour of the South African financial markets with regards to the Geometric Brownian motion process. It uses the daily, weekly, and monthly stock returns time series of some major securities ...
Seasonal effects on the feeding ecology and habitat of Chersina Angulata in the South Western Cape
(University of the Western Cape, 2008)
Nearly one-third of the world’s tortoises live in South Africa, but little is known about their habitat requirements and feeding ecology. Chersina angulata, the angulate tortoise, is endemic to southern Africa, with a ...
Synergistic effects of mixtures of fungicides and medicinal plant extracts against Botrytis cinerea
(University of the Western Cape, 2008)
We hypothesize that South African medicinal plants contain compounds that can act in synergism with synthetic antifungal compounds. Four fungicides - Sporekill™, Rovral™, Terminator™ and Teldor™ at doses 0.1, 0.2, 0.4 and ...
Virtual human modelling and animation for real-time sign language visualisation
(University of the Western Cape, 2008)
This thesis investigates the modelling and animation of virtual humans for real-time sign language visualisation. Sign languages are fully developed natural languages used by Deaf communities all over the world. These ...
The establishment of the long-term rainfall trends in the annual rainfall patterns in the Jonkershoek Valley, Western Cape, South Africa
(University of the Western Cape, 2008)
The overall aim of this project was to establish whether there is a long-term decline of rainfall collected in rainfall gauges within the Jonkershoek Valley that have the longest and best quality records.
Implications of the geological structure of the Qoqodala dolerite ring complex for groundwater dynamics
(University of the Western Cape, 2008)
The chief aim of this project is to investigate the groundwater flow dynamics of the various fractured-rock aquifers (deep and shallow) associated with Karoo dolerite ring complexes in the Qoqodala area (northeast of ...
The ecology of the world's smallest tortoise, homopus signatus signatus: effects of rainfall
(2008)
Tortoises appear to be successful in arid ecosystems, where they depend on primary production for their predominantly herbivorous diets. The low primary production of arid regions is exacerbated by priodic droughts, so ...
An in vitro study on the immunotoxicity of sewage effluents discharged into the Eerste River-Kuils river water catchment system
(2008)
"The aim of the study was to use in vitro human whole blood cultures to screen the water samples collected from the Eerste/Plankenbrug river system for cytotoxicity and inflammatory activity and for the first time investigate ...
The determination of boron using 11B(p, α)8Be nuclear reaction
(UWC, 2008)
Determination of trace quantities of boron is required in various studies of materials and in geology. Using 11B(p, α)8Be nuclear reaction with focused proton beam of 670 keV energy is one of the few microanalytical ...
