Drive implementation of a permanent magnet synchronous motor
(North-West University, 2007)
The North-West University has been focussing on the development and implementation of active magnetic bearings (AMBs) as well as the modelling and control of the AMBs. Recently the need for a high speed flywheel system ...
The development of a fully suspended AMB system for a high-speed flywheel application
(North-West University, 2007)
The School of Electrical, Electronic and Computer Engineering at the North-West University is currently in the process of developing an active magnetic bearing (AMB) laboratory. The idea is to establish a knowledge base ...
Critical evaluation of occupational health and safety management in Sasol retail convenience centres
(North-West University, 2007)
Occupational health and safety management has continued to take the centre stage in the decision making process in most organisations. This is further fostered by agitation from labour unions and government intervention ...
Utilities optimization in a wax process plant
(North-West University, 2007)
In this dissertation, the extent of utilities optimization, conservation and management is investigated in a case study plant (Sasol Wax plant). At the outset, the particular types of utilities in the case study plant were ...
New demand side management opportunities in the precious metals industry
(North-West University, 2007)
Currently there is an increasing demand for energy across the world. As the human population increases and new technologies find their way to previously difficult to reach areas, this is becoming an increasing problem. ...
Sustainable DSM on deep mine refrigeration systems : a novel approach
(North-West University, 2007)
The supply and demand of energy have become a world wide concern. It is predicted that world energy usage could increase from 15TW, to 21TW by 2020. In South Africa the peak demand for electrical energy has already outrun ...
Dynamic modelling of the natural convection water cooling principle
(North-West University, 2007)
The aim of this project is to investigate the operating characteristics of the Reactor Cavity Cooling System (RCCS) of the Pebble Bed Modular Reactor (PBMR) demonstration power plant during the active and passive operation ...
The applicability of an existing tube condenser model when used with refrigerant R-407C
(North-West University, 2007)
The Montreal Protocol resulted in the phase out of ozone depleting refrigerants like chloroflourocarbons (CFC) and hydrochloroflourocarbons (HCFC) used in refrigeration and heat pump applications. In heat pump applications ...
Reduce maintenance resources and increase plant availability by utilising web-based condition monitoring systems and Markovian modeling techniques
(North-West University, 2007)
The purpose of this research is two-fold. Firstly, to decrease maintenance resources and
increase plant availability and secondly, to investigate the feasibility of using Web-based
condition-monitoring techniques as a ...
Development, characterisation and verification of an integrated design tool for a power source of a soya business unit
(North-West University, 2007)
Selecting a suitable power source, during the design process, for a stand-alone soya business unit is challenging and complex. Especially with the aim of optimizing electrical and thermal energy, as well as minimizing the ...
