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 ...
Automatic calibration of a tool-changing unit for modular reconfigurable machines.
(2011)
Modern trends in customer demand have resulted in the development of a class of
manufacturing system known as Reconfigurable Manufacturing Systems (RMS).
Reconfigurable systems are designed around the idea that they must ...
Maritime tracking using level sets with shape priors.
(2012)
Piracy is still a significant threat to ships in a maritime environment. Areas such as the coast of Somalia
and the Strait of Malacca are still plagued by pirates, and the total international cost of piracy numbers
in ...
Characteristics of rain at microwave and millimetric bands for terrestrial and satellite links attenuation in South Africa and surrounding islands.
(2010)
The emergence of a vast range of communication devices running on different types of technology has made convergence of technology become the order of the day. This revolution observed in communications technology has ...
An investigation of solar powered absorption cooling systems for South Africa.
(2012)
Increased standards of living and indoor comfort demands have led to an increase in the demand
for air-conditioning in buildings in South Africa. Conventional vapor compression systems use
refrigerants that damage the ...
A study of fire-induced air-gap voltage breakdown characteristics under HVDC conditions.
(2012)
This dissertation investigates the role that is played by high temperatures of air gaps on the
breakdown voltage levels under DC positive and negative polarity applied voltages. Due to
past experience of AC transmission ...
The application of electrical resistance tomography within a vacuum sugar pan in order to better understand its boiling dynamics.
(2010)
This dissertation is concerned with the application of tomography within the sugar industry; in particular non-accessible locations found in a sugar mill. In this study, the focus of research is that of a vacuum pan, and ...
Controlling chaos in a sagittal plane biped model using the Ott-Grebogi-Yorke method.
(2012)
Controlling a system with chaotic nature provides the ability to control and maintain orbits of different
periods which extends the functionality of the system to be flexible. A system with diverse dynamical
behaviours ...
The development and application of a real-time electrical resistance tomography system.
(2012)
This dissertation focuses on the application of tomography in the sugar milling process, specifically
within the vacuum pan. The research aims to improve the efficiency and throughput of a sugar mill by
producing real-time ...
An investigation into the feasibility of migrating from PILC to XLPE as the cable technology of choice for medium voltage electricitiy networks in South Africa.
(2011)
South African medium voltage underground electrical networks consist mainly of cables of
paper insulated lead covered construction. This construction is still the standard used for most
utilities in South Africa. While ...
