Design of an active magnetic bearing system for a high-speed permanent magnet synchronous machine
(North-West University (South Africa), 2020)Currently, there are two high-speed permanent magnet synchronous machines (HS-PMSMs), nicknamed the TWINS, situated in the McTronX laboratory at the North-West University. However, excessive heat generated by the ball ... -
CREAK descriptor evaluation for monocular visual SLAM
(North-West University (South Africa), 2020)This dissertation evaluates the novel Colour-based Retina Keypoint (CREAK) feature descriptor with the current state of the art, Fast Retina Keypoint (FREAK) feature descriptor in the context of a visual Simultaneous ... -
Application of a magnetic cyclone on a magnetite dense medium separation process
(North-West University (South Africa), 2020)The face of coal supply and demand is ever-changing, with the demand for clean coal rising and with a dwindling supply of high quality ore. Methods to efficiently clean the coal of worsening run-of-mine quality are ... -
Improving air distribution in deep-level mine ventilation systems
(North-West University (South Africa), 2020)Improving underground mine conditions results in fewer ventilation-related fatalities and increases productivity. The objective of a subsurface ventilation system is to ensure sufficient quantity and quality of airflow in ... -
Structuring data to capture energy reticulation knowledge
(North-West University (South Africa), 2020)Energy management is essential due to the increase in energy costs and its effects on the environmental footprint of an industrial site. Managing energy is an essential but complicated task. This complexity derives itself ... -
Development of Corridor Performance Benchmarking Dashboards
(North-West University (South Africa), 2020)Chapter Overview: Trade corridors can be defined as a culture of trade agreements and treaties, statutes, delegated legislation and customs that govern and guide trading relationships [1]. Trade corridors are in essence a ... -
Initial implementation of the neutronics codes DRAGON and DONJON at the North-West University
(North-West University (South Africa), 2020)The neutronics research group at the North West University plans to use open source neutronics in some of the future research that will be conducted by the group. The open source neutronics codes DRAGON and DONJON were ... -
The solution processing and stoichiometry of ZrC
(North-West University (South Africa), 2020)In the aftermath of the incident at Fukushima Daiichi, evaluation of alternative Accident-Tolerant Fuel (ATF) was initiated. The purpose of ATF systems is to achieve greater safety margins by delaying the initiation of ... -
The synthesis and use of nitrogen derived titanates for the adsorption of uranium from aqueous waste streams
(North-West University (South Africa), 2020)The synthesis and use of layered hydrazinium and ammonium titanate as an adsorbent for uranium in a nitric acid solution was investigated. Several different titanate synthesis methods were identified from literature. Three ... -
Winnowing as a dry separation method for fine coal
(North-West University (South Africa), 2020)Dry coal processing is fast becoming favoured as a fine coal beneficiation technique. The decline in suitable good-quality coal, as well as the ongoing decrease in usable process water, makes dry beneficiation of the fine ... -
Increasing overall equipment effectiveness of drilling machines by means of data driven dashboards
(North-West University (South Africa), 2020)The decline in revenues, within the South-African mining sector, over the last decade is troublesome, considering a significant level of employment it creates. This study aims to create a link between improved operations ... -
Intelligent controller for a hybrid energy storage system
(North-West University (South Africa), 2020)The performance and range of electric vehicles are largely determined by the characteristics of the electrical energy storage (EES) device used. The EES should be sufficiently sized to be able to provide the necessary ... -
Evaluating different statistical regression models for industrial energy measurement and verification
(North-West University (South Africa), 2020)The worldwide concern regarding the environmental impact of using fossil fuels as an energy source leads to the increased interest in improving energy efficiency. The energy efficiency of existing facilities can be improved ... -
Development of processes to improve sustainability of industrial IDM projects
(North-West University (South Africa), 2020)Eskom, the primary supplier of electricity in South Africa, is struggling to keep up with the country’s demand. This led to the creation of the Integrated Demand Management (IDM) Division which funds projects implemented ... -
Understanding customer preferences: comparing additive manufacturing powders (PA2200 & PA2221) in a South African context
(North-West University (South Africa), 2020)This study aims to determine the properties of polymer powders for laser sintering (LS) which are most desirable from a customer perspective. With multiple options of imported material being available, it is possible to ... -
Residential electrification design topology evaluation model - the sustainable approach for residential developments
(North-West University (South Africa), 2020)Residential development electrification is a key societal element which signifies development in developing countries. The impact of the residential development needs to cater not only for the current needs, but consider ... -
Automatic Modulation Classification through clustering in the I/Q plane
(North-West University (South Africa), 2020)Automatic Modulation Classification (AMC) refers to a process where the modulation scheme of a signal of interest is determined. It is not a requirement of an AMC system to recover the original data contained in the signal. ... -
Performance and fouling prediction model for finned-tube heat exchangers
(North-West University (South Africa), 2020)Finned-tube heat exchangers (FTHXs) are found in abundance in heating, ventilation, and air-conditioning (HVAC) systems. This vital piece of equipment is used to either cool or heat the occupational environment. The thermal ... -
The zonal approach applied to the simulation of the radiative heat transfer in a packed pebble bed
(North-West University (South Africa), 2020)The Fukushima Daiichi Nuclear Disaster highlighted the importance of nuclear safety and the importance of modeling a nuclear reactor under diverse conditions. Applied to pebble bed reactors, these diverse conditions include ...
