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 ...
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 ...
Development of granular-medium-based energy management system for automotive bumper applications

Maina, Mwangi Festus (2009)

Automotive bumpers are installed primarily to minimize damage and harm to both the automobile and passengers during minor and low speed collisions. The efficacy of the current bumper systems lies in absorbing the impact ...
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 ...
A hybrid simulation technique to predict the effects of human deterioration and learning in an industrial environment

Hay, Graeme Kenneth (2009)

Process simulation is an effective tool when used to simulate a system where a great deal of data exists for the process. This technique is however limited when it comes to simulating certain non-deterministic parts such ...
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. ...
The infrastructure cost planning model : an integrated solution to cost effective design

Saroop, Shian Hemraj (2009)

Infrastructure project costs are being scrutinised more closely and with greater skill and accuracy as projects have become larger, more complex and more expensive, and clients have become more exacting in their requirements. ...
Design and implementation of an intelligent vision and sorting system

Li, Zhi (2009)

This research focuses on the design and implementation of an intelligent machine vision and sorting system that can be used to sort objects in an industrial environment. Machine vision systems used for sorting are either ...
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 ...
The development of an advanced composite structure using evolutionary design methods

Van Wyk, David (2008)

The development of an evolutionary optimisation method and its application to the design of an advanced composite structure is discussed in this study. Composite materials are increasingly being used in various fields, ...
The effect of biomass acclimation on the co-digestion of toxic organic effluents in anaerobic digesters

Chamane, Ziphathele (2008)

Currently KwaZulu-Natal (KZN) province is populated with textile industry, which produces wastewater, some of which is not biodegradable. Due to the stringent environmental regulations the wastewater cannot be discharged ...
Fracture properties of fibre and nano reinforced composite structures

Ramsaroop, Avinash (2007)

Interlaminar cracking or delamination is an inherent disadvantage of composite materials. In this study the fracture properties of nano and fibre-reinforced polypropylene and epoxy composite structures are examined. These ...
The in-service determination of the presence of distortion in a high quality analogue sound signal

Mare, Stefanus (2007)

Detecting and minimising distortion in audio signals is an important aspect of sound engineering. Distortion of a signal passing through an audio system may be caused by a number of factors and it is necessary to detect ...
Development of system for teaching turbo code forward error correction techniques

Shi, Shuai (2007)

The objective was to develop a turbo code demonstration system for educational use. The aim was to build a system that would execute rapidly and produce a graphical display exemplifying the power of turbo codes and showing ...
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 ...
Increasing the use of fibre-reinforced composites in the Sasol group of companies : a case study

Mouton, Jacques (2007)

A composite material comprises two or more materials with properties that are superior to those of the individual constituents. Composites have become important engineering materials, especially in the fields of chemical ...
Development of a hybrid fuzzy-mathematical cleaner production evaluation tool for surface finishing

Telukdarie, Arnesh (2007)

The metal finishing industry has been rated among the most polluting industries worldwide. This industry has traditionally been responsible for the release of heavy metals such as chrome, nickel, tin, copper etc into the ...
