A study of rain attenuation on terrestrial paths at millimetric wavelengths in South Africa.
(2006)Rain affects the design of any communication system that relies on the propagation of electromagnetic waves. Above a certain threshold of frequency, the attenuation due to rain becomes one of the most important limits to ... -
Adaptive multiple symbol decision feedback for non-coherent detection.
(2006)Non-coherent detection is a simple form of signal detection and demodulation for digital communications. The main drawback of this detection method is the performance penalty incurred, since the channel state information ... -
Adaptive sedimentation and patch optimization for multi-viewed stereo reconstruction.
(2015)This dissertation presents two main contributions towards the Patch-based Multi-View Stereo (PMVS) algorithm. Firstly, we present an adaptive segmentation method for preprocessing input data to the PMVS algorithm. This ... -
The Analysis of computer systems for performance optimisation.
(1987)The project investigated the problem of performance optimisation of computer systems at the systems level. It was ascertained that no generally accepted technique for approaching this problem exist. A theoretical approach ... -
Analysis of high voltage current transformer under deteriorating and failed insulation.
(2006)Data pertaining to the number of failed high voltage current transformers installed in -
Analysis of the impact of closed-loop power flow control strategies on power system stability characteristics.
(2014-03-31)The demand for electrical energy in industrialised countries continues to increase steadily. As a result of this growing demand for electrical energy, there is a need for optimisation of the power system in terms of ... -
The application of controllable inverter-based series compensation to power oscillation damping.
(2000)Poorly damped oscillations that occur between the generators in large interconnected power systems often limit the amount of power that can be transmitted through a transmission corridor and are a threat to secure system ... -
Application of distance protection for transformers in Eskom transmission.
(2014)Eskom is South Africa’s state owned utility who is responsible for the generation, transmission and distribution of electricity. The transmission network in Eskom consists of thousands of kilometres of lines operating at ... -
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 ... -
Application of HVDC technology in medium voltage distribution systems.
(2005)Approximately 60% of all South Africans do not have access to electricity from the national grid and 80% of the dwellings in the rural areas are not electrified. This is due to the fact that many rural South Africans, ... -
Application of quantitative feedback theory to robust power system stabiliser design.
(2003)This thesis aims to verify the use of quantitative feedback theory (QFT) as a viable tool for designing power system stabilisers (PSS) for a single machine infinite bus system. The result of the QFT design is verified by ... -
The application of volt/var optimisation on South African distribution power networks.
(2016)Electric power utilities can achieve cost savings by maximizing energy delivery efficiency and optimizing peak demand. Technical losses are influenced by both network impedances and currents. Power flow through distribution ... -
An application specific low bit-rate video compression system geared towards vehicle tracking.
(2003)The ability to communicate over a low bit-rate transmission channel has become the order of the day. In the past, transmitted data over a low bit-rate transmission channel, such as a wireless link, has typically been ... -
Assessment of the electrical performance of the Cahora Bassa HVDC scheme.
(2005)The aim of this study was to assess the electrical performance of the Cahora Bassa HVDC scheme. For practical reasons a database was developed to hold and analyse the performance data. Microsoft® Access 2002 relational database ... -
Asset health appraisal of transformers in Eskom's distribution network.
(2017)Master of Science in Electrical Engineering. University of KwaZulu-Natal, Durban 2017. -
Automated hybrid solar and mains system for peak time power demand.
(2015)The power demand during peak period causes large power fluctuations in the commercial grid. The reduction in using grid supply during peak time benefits the supplier and consumer. There are many methods such as monitoring ... -
Beach water quality : a comprehensive analysis of the pathogenic pollution of the Durban coastline.
South Africa's beaches have many local and international visitors. Various recreational activities occur along the Durban coastline, especially during the holiday seasons. Beach water quality is negatively affected by ... -
Bird streamer initiated breakdowns under HVDC conditions.
(2007)This dissertation describes the role played by bird streamers in transmission line faults under HVDC conditions. The research was initiated due to the lack of knowledge of these faults under HVDC conditions. An explanation ... -
Broken PEN conductor in the context of rural South African households.
(2015)Low voltage distribution systems often receive the least attention as faults affect fewer customers and the elemental value of the network is insignificant compared to other parts of the grand electrical system. Ironically, ... -
Colour measurement and colour reproduction systems.
(1987)Techniques of colour measurement and colour reproduction are important in a wide range of commercial and social activities in most modern economies. Their study thus constitutes one of the major areas of interest to the ...
