Best practice for personnel, material and rock transportation in ultra deep level gold mines.
(2003)Ultra deep mining presents many challenges to the mining engineer, one of which is the logistics to support mining operations quickly and efficiently. Typically, Witwatersrand gold mines operate at depths in excess of 2000 ... -
Bio-mechatronic implementation of a portable upper limb rehabilitative exoskeleton.
(2011)The rationale behind this research originates from the lack of public health care in South Africa. There is an escalation in the number of stroke victims which is a consequence of the increase in hypertension in this ... -
Broadband solar radiometric measurements in the greater Durban area.
(2011)This work comprises a radiometric study of Durban‟s solar resource, utilizing data from the Howard College campus of the University of KwaZulu-Natal (UKZN), and the Solar Thermal Applications Research Laboratory (STARlab) ... -
Buckling of short, thin-walled cylinders, as applied to storage tanks.
(2001)This is an investigation of the buckling characteristics of short, thin-walled cylinders. This study was required as large storage tanks, which were converted from Boating roof to fixed roofed tanks, were found to buckle ... -
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 ... -
Closed-loop throttle control of a hybrid rocket motor.
(2018)Hybrid rocket motors produce thrust by reacting a solid fuel with a liquid oxidizer inside a combustion chamber. This approach has certain advantages over conventional solid propellant rockets including improved safety and ... -
Combustion studies of biodiesel fuel from moringa, jatropha and restaurant oil.
(2016)Biodiesel is a renewable alternative to finite diesel and, has the capacity to reduce emission and broaden energy access particularly in sub-Saharan Africa where economic growth has been, to some extent, constrained ... -
Communication, mapping and navigational aspects for a free-ranging, automated guided vehicle.
(1992)A free-ranging automated guided vehicle incorporating navigation and radio communication for use in a fully automated flexible manufacturing system has been developed. A vehicle, operating as a complete subsystem, was built ... -
A comparative study on the effects of internal vs external pressure for a pressure vessel subjected to piping loads at the shell-to-nozzle junction.
(2003)This investigation seeks to perform a comparative study between the combined effects of internal pressure and piping loads versus external pressure and piping loads on a pressure vessel. There are currently several well-known ... -
Computational and analytical modelling of composite structures based on exact and higher order theories.
(1995)The objective of the present study is the computational and analytical modelling of a stress and strain state of the composite laminated structures. The exact three dimensional solution is derived for laminated anisotropic ... -
The computational investigation of the wind-induced vibration of overhead conductors.
(2013)The reliable transmission of high-voltage electricity through overhead electrical conductors is a cornerstone of the modern industrialised world. Any situation or phenomenon that impedes the functioning of this network ... -
Condition monitoring of a rotor bearing system.
(2011)The key objective for this research was to construct an experimental test rig along with a finite element model. Both had to accommodate a certain extent of misalignment and unbalance to provide induced vibrations in the ... -
Contractible arms elevating search and rescue (Caesar) robot : improvements and modifications for urban search and rescue (Usar) robots.
(2010)Rescuers have lost their lives in events requiring them to go into dangerous areas that have unstable structures and gases. Robots are necessary for search and rescue purposes, to access concealed places and environments ... -
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 cooperation of heterogeneous mobile robot configurations in advanced manufacturing environments.
(2014)Cooperation of Multiple Mobile Robot Systems (MMRS) have drawn increasing attention in recent years since these systems have the ability to perform complex tasks more efficiently compared to Single Mobile Robot Systems ... -
Cordless linear synchronous motor material handling system for computer integrated manufacturing.
(2000)Advanced material handling systems' impact on flexible manufacturing systems (FMS) have increased the efficiency and work rate over conventional manufacturing assemblies. The interaction of automated guided vehicles ... -
Coriolis effect on the stability of convection in mushy layers during the solidification of binary alloys.
(2000)We consider the solidification of a binary alloy in a mushy layer subject to Coriolis effects. A near-eutectic approximation and large far-field temperature is employed in order to study the dynamics of the mushy layer ... -
Crashworthiness modelling of SMC composite materials.
(2003)The purpose of this research is to make an investigation into the crashworthiness modelling of Sheet Moulding Compound (SMC) composite materials, and to study the response of SMC composite structures under dynamic loading. ... -
Crashworthiness modelling of thin-walled composite structures.
(2003)This thesis is concerned with the study of the crashworthiness of thin-walled composite structures. Composites are being used more and more in different fields of engineering, particularly, in aerospace and automotive ... -
Critical tracking and stress analysis of Transnet engineering trailers.
(2017)Transnet Engineering (TE) produces specialised trailers that are not commercially available. The design of the trailers is based on experience plus knowledge of original equipment manufacturer (OEM) designed and operational ...
