Hybridisation of energy storage for multiple input DC-DC converters
(2019-05)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 ... -
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 ... -
Numerical modelling of the flow and heat transfer in a prismatic block VHTR singlechannel fuel module
(North-West University (South Africa). Potchefstroom Campus, 2019)No Abstract available -
Condition based reliability simulator for power stations
(North-West University (South Africa). Potchefstroom Campus, 2018)The SA Power Utility operates 27 power stations with a total nominal capacity of 41,995 MW, comprising 35,726 MW of coal-fired stations, 1,860 MW of nuclear, 2,409 MW of gas–fired, 2,000 MW hydro and pumped–storage stations ... -
Simulating operational improvements on mine compressed air systems
(North-West University (South Africa). Potchefstroom Campus, 2018)As the operational costs of deep-level mines increase and gold ore grades decrease, profitability in the South African gold mining sector is becoming a challenge. Electricity tariff increases moreover contribute to the ... -
Optimising production through improving the efficiency of mine compressed air networks with limited infrastructure
(North-West University (South Africa). Potchefstroom Campus, 2017)The global gold mining industry is currently on a growing trend, while the local gold mining industry in South Africa has been experiencing a decline in gold production. This is due to a unique set of production challenges ... -
The dry beneficiation of South African small coal in a dense medium fluidized bed
(North-West University, 2018)Conventionally, wet processing was preferred to beneficiate coal based on its sharp separation efficiency; however, the excessive process water constraint is an extreme drawback and proves that wet beneficiation is currently ... -
Comparison of feature-based classifiers in Automatic Modulation Classification systems
(North-West University, 2018)In South Africa, the telecommunications regulator, ICASA, follows a ?xed spectrum allocation approach. The radio spectrum is assigned to incumbents (primary users) on a long-term basis. This practice follows a wholesale ... -
The experimental evaluation of nitrogen transformation in South African coal chars and the concomitant release of nitrogenous species
(North-West University, 2018)The effect of typical South African (SA) coal properties on nitrogen functional transformation and release were examined in the course of pyrolysis in a fluidised bed (FB) and drop-tube furnace (DTF). Chars were generated ... -
Induction motor efficiency test methods: a comparison of standards
(North-West University, 2018)In this work, fundamental aspects regarding the efficiency of induction motors are treated. Improved efficiency is the task of the hour. Environmental challenges, which include climate change, global warming and greenhouse ... -
Improving energy cost performance of steel production mills
(North-West University, 2018)The global steel supply capacity is more than the demand. This has caused an increase in competition and imports to some countries. South Africa is one of the affected countries and the effects have been seen in the closing ... -
Mine ventilation characterisation through simulations
(North-West University, 2018)The profitability of the mining industry is contingent on the industry’s ability to improve upon the status quo of operational efficiency. If the archaic operating methods of mines are altered to embrace and incorporate ... -
Extracting complexity metrics of technological artifacts and systems from patents using patent document structure
(North-West University, 2018)This study investigates the relationship between different complexity metrics from the literature and metadata fields in patents. Patent citations, claims and other fields are compared against complexity metrics derived ... -
An integrated software platform for the efficient management of projects
(North-West University, 2018)Electronic software platforms play a role in the internal processes and management of projectbased firms. Many task-based solutions exist in practice to handle projects e ciently. These tools address shortcomings that ... -
Investigation into the coupled 1D and 3D numerical modeling of an air-cooled heat exchanger configuration
(North-West University, 2018)One dimensional (1-D) systems CFD can be used to simplify the analyses of thermal-fluid problems with complex geometries as it has the capability to provide quick solutions on fluid dynamics such as pressure changes, ... -
Neutron and X-Ray tomography as research tools for applied research in South Africa
(North-West University, 2018)The use of penetrating radiation for non-destructive investigations, through the use of radiography and tomography, provides for powerful research tools. Development of such experimental facilities, and the establishment ... -
Using thorium to decrease maximum DLOFC temperatures and increase total power output in Pebble-Bed High Temperature Reactors
(North-West University, 2018)This is a study on the topic of modifying the fuel cycles of Pebble-Bed Reactors in order to reduce their maximum fuel temperatures during Depressurised Loss of Forced Coolant (DLOFC) accidents, in order to prevent ... -
Expanding industrial thinking by formalizing the industrial engineering identity for the knowledge era
(North-West University, 2018)This PhD study provides a multi-perspective view of Industrial Thinking and the Industrial Engineering profession. The aim is to formalize the Industrial Engineering identity and expand its associated thinking style to ... -
A study of electrical motor management: engineering services department within a large steel manufacturer as case study
(North-West University, 2018)Electrical motors are the true work horses within industry and these electrical motors have to be managed. This study focuses on a large steel manufacturer's motor population within the engineering service department (ESD) ...
