Object motion detection, extraction and filtering using ANN ensembles

Moorgas, Kevin Emanuel (2009)

This research is devoted to the development of an intelligent image motion detection system based on artificial neural networks (ANN’s). Object motion detection, non-stationary image isolation and extraction, and image ...
A particle swarm optimization approach for tuning of SISO PID control loops

Pillay, Nelendran (2008)

Linear control systems can be easily tuned using classical tuning techniques such as the Ziegler-Nichols and Cohen-Coon tuning formulae. Empirical studies have found that these conventional tuning methods result in an ...
Process development for co-digestion of toxic effluents : development of screening procedures

Dlamini, Sithembile (2009)

The primary objective of this project was to establish a screening protocol which could be used to access high strength/toxic effluent for toxicity and degradability prior to being disposed in wastewater treatment ...
The purification of corn steep liquor as a fermentation feedstock by ultrafiltration

Govender, Devan (2010)

THE OBJECTIVE of this study was to devise a purification process, using ultrafiltration membranes as the core technology, for the preparation of corn steep liquor (CSL) as a fermentation feedstock. This process inherently ...
Separation processes for high purity ethanol production

Ngema, Peterson Thokozani (2010)

Globally there is renewed interest in the production of alternate fuels in the form of bioethanol and biodiesel. This is mainly due to the realization that crude oil stocks are limited hence the swing towards more renewable ...
The synthesis, structure and properties of polypropylene nanocomposites

Moodley, Vishnu Kribagaran (2007)

Polymer nanocomposites may be defined as structures that are formed by infusing layered-silicate clay into a thermosetting orthermoplastic polymer matrix. The nanocomposites are normally particle-filled polymers for ...
Travel patterns and safety of school children in the eThekwini Municipality

Dhoda, Salma (2009)

The annual incidence of pedestrian casualties on South African roads is approximately 34 000. This includes 4 000 deaths, 10 000 serious injuries and 20 000 minor injuries, costing the country an estimated R2,55 billion. ...
Use of evaporative coolers for close circuiting of the electroplating process

Munsamy, Megashnee (2011)

The South African electroplating industry generates large volumes of hazardous waste water that has to be treated prior to disposal. The main source of this waste water has been the rinse system. Conventional end-ofpipe waste ...
Use of piezoelectric techniques monitoring continuum damage of structures

Nhassengo, Sikhulile Khululeka (2011)

The objective of the present study was to investigate if piezoelectric techniques or sensors can be used in monitoring structural degradation. The study considers experimental results and analytical modelling of a ductile ...
Utilisation of Maqalika Reservoir as a source of potable water for Maseru city in Lesotho

Letsie, Masupha (2005)

Lesotho is a land locked country, entirely surrounded by the Republic of South Africa. Maseru is the capital of Lesotho and the country’s main centre for commerce and industry. The study area is located on the North-Eastern ...
