Implementation of a proprietary CAD graphics subsystem using the GKS standard interface.
(1989)
This project involved porting a Graphical Software Package (GSP) from
the proprietary IDS-BO Gerber CAD system onto a more modern computer that
would allow student access for further study and development. Because of the ...
Design, modelling and simulation of 2 novel 6 DOF hybrid machines.
(2012)
Industrial robot arms are an essential part of automated manufacturing, and perform tasks
such as component assembly, welding, light machining, spray painting, etc. They are highly
repeatable, can be calibrated to be ...
An investigation of new heterogeneous hydrotalcite-like catalysts for the cis-dihydroxylation of olefins.
(2004)
The use of supported catalysts to essentially combine the positive traits offered by both homogeneous and heterogeneous catalysis has become a competitive field of research. In particular, hydrotalcite-like catalysts (HTIc) ...
End-pumped solid-state lasers.
(2010)
This dissertation consists of four sections, with the focus on near- and mid-infrared lasers using Yttrium Lithium Fluoride (YLF) crystals doped with various rare-earth ions as a gain medium. As introduction a general ...
Clifford-Fischer theory applied to certain groups associated with symplectic, unitary and Thompson groups.
(2012)
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 ...
The biology, ecology and conservation of four Flufftail species, Sarothrura (Aves: Rallidae)
(1994)
The distribution, status, biology and ecology of four flufftail species were investigated in South Africa and Zimbabwe. The Redchested Flufftail is a successful and widely distributed species, occupying a wide range of ...
Biological activity of traditional medicinal plants used against venereal diseases in South Africa.
(2006)
Throughout the history of mankind, many infectious diseases have been
treated with plant extracts. Venereal infections are one such group and are regarded
as conditions that are highly responsive to traditional treatment. ...
In vitro propagation of Scilla natalensis planch.
(1999)
In South Africa, large quantities of Scilla natalensis are harvested from wild populations
and sold as traditional medicine, which is reducing the density, distribution and genetic
diversity of wild populations. The ...
Case study of bird streamer caused transient earth faults on a 275KV transmission grid.
(2001)
This thesis discusses the results of an investigation that was initiated in January
1996 to determine the root cause of the increasing fault trend in respect of
transient earth faults on the 275 kV transmission grid ...
Spatial modelling of fire dynamics in Savanna ecosystems.
(1999)
Fire is used in the management of ecosystems worldwide because it is a relatively inexpensive means of manipulating thousands of hectares of vegetation. Deciding how, where and when to apply fire depends primarily on the ...
