Cooperative control of an active magnetic bearing and sensorless drive system
(North-West University (South Africa). Potchefstroom Campus, 2019)
This thesis presents the cooperative control of an active magnetic bearing (AMB) and sensorless drive system. Traditionally, these two systems are considered as independent modular components within a larger system. The ...
Novel biochemical and catalytic microwave-assisted methods for the synthesis of biobutanol
(North-West University (South-Africa). Potchefstroom Campus, 2019)
Biofuels such as bio-ethanol, bio-butanol and biodiesel are attractive fuel substitutes to negate the negative effects of fossil fuel use. Bio-butanol, in particular, is of interest because of its properties, such as; low ...

An integrated methodology to measure and verify energy conservation under incentive-based irrigation pumping programmes
(North-West University (South Africa), 2019)
Water scarcity and droughts have become a looming threat in many counties worldwide. In South Africa, a water crisis is upon the country and estimations show a supply shortfall of 17% by 2030. When considering water ...
Simulation of externally fired gas turbine configurations for micro-scale biomass applications
(North-West University (South Africa)., 2019)
Most rural communities in South Africa are forced to rely on alternative energy resources such as biomass, gas, liquid fuels and waste materials for the provision of energy to fulfil their lighting and cooking needs since ...

Hybridisation of energy storage for multiple input DC-DC converters
(2019)
One of the biggest challenges towards achieving efficient and effective energy use in electric
vehicles is the energy storage systems. Batteries, though being improved with newer
technologies, are still not capable of ...
Uncertainty and sensitivity analysis of aspects of the neutronics of a prismatic block-type HTGR
(2019)
The International Atomic Energy Agency (IAEA) Coordinated Research Project (CRP) on High
Temperature Gas-cooled Reactors (HTGR) Uncertainty Analysis in Modelling (UAM) has been
established aiming to study uncertainty ...
A critical analysis of emission quantification methods in the ferrochrome industry
(North-West University (South Africa)., 2019)
Ferrochrome (FeCr) furnaces are significant CO2 emitters due to the large amounts of carboncontaining
materials being used. FeCr industries will therefore become liable for carbon tax (CT),
which is set for implementation ...
Comparison between trajectory models for firing table application
(North-West University, 2019)
Firing tables are mainly based on trajectory models such as the Point Mass model, the Modified Point Mass model or the Five Degree of Freedom model. This research investigates and provides a comparison between these models ...
