A novel Decision Support System for modern Relational and Non-Relational Database Systems
(North-West University (South Africa)., 2023)Data-based application design and development can be complex and difficult to navigate. With relational and non-relational database technologies, each with divergent paradigms, it is not apparent how to make the correct ... -
A simulation-based horizontal water transport management strategy in deep-level mines
(North-West University (South Africa)., 2023)Dewatering and water transfer pumping are two of the main consumers of electricity in the South African mining industry. In the ever-unstable electricity supply regime, it is important to consider all possible angles to a ... -
Degradation of polycyclic aromatic hydrocarbons from coal tar aqueous solutions using photo-biocatalysts
(North-West University (South Africa)., 2023)Polycyclic aromatic hydrocarbons (PAHs) are amongst the most predominant pollutants that are currently released into the environment. Despite the myriad of environmental regulations enforced by governments in countries ... -
Modeling power failures in deep-level mines to assist with emergency dewatering planning
(North-West University (South Africa)., 2023)A mining complex’s intricate dewatering system removes water that enters the shaft through various means. This system comprises a series of water pumps that require a constant power supply to avoid flooding key areas of ... -
Target profiles for critical parameters in compressed air systems to reduce missed energy savings opportunities
(North-West University (South Africa)., 2023)The reducing profit margins of South African mines pose a financial and economic risk for South Africa. The decrease in gold production and the increase in operational costs are contributing factors to the reduction of ... -
Effect of powder characteristics and layer thickness on the densification of Selective Laser Melted CoCrMo
(North-West University (South Africa)., 2023)Selective laser melting (SLM) is a metal additive manufacturing (AM) process that fabricates parts according to a CAD design in a layer-by-layer fashion by melting metal powder. There are a vast number of powder-related ... -
Improvement of XFOIL lift and drag predictions
(North-West University (South Africa)., 2023)XFOIL is a fast and relatively accurate panel method to analyse 2D airfoil performance. XFOIL has proven itself over many years to be a powerful airfoil design and analysis tool. From the literature and through the various ... -
Holistic evaluation of surface cooling plant configurations for different seasons at deep mines
(North-West University (South Africa)., 2023)The mining sector consumes a large portion of South Africa’s electricity. Deep mining contributes to 15% of the total electricity consumption in South Africa. Mining electricity costs in South Africa have increased by 655% ... -
Experimental evaluation of biaxial out-of-phase fatigue life failure criteria
(North-West University (South Africa)., 2023)Complex multiaxial fatigue loading conditions often arise in mechanical components like crankshafts, propeller blades and gas turbines. The loading conditions are often out-of-phase, and the out-of-phase fatigue limit ... -
Improving demand-side pressure of compressed air distribution networks in mines
(North-West University (South Africa)., 2023)The Platinum Group Mining industry is a large contributor to South Africa’s economy. Approximately 90% of the world’s remaining platinum group metals are in South Africa, with 54% of the global palladium & platinum mined ... -
Investigation into the effect of printing temperatures on material properties of fused filament fabricated components
(North-West University (South Africa)., 2023)Three-Dimensional (3D) Printing is increasingly becoming a reality in everyday industrial applications. This technology works on the principal of layering strand upon strand and ultimately layer upon layer of printing ... -
Testability in an IoT system : a full life cycle perspective
(North-West University (South Africa)., 2023)The Internet-of-Things (IoT) has brought about a major paradigm shift to traditional system analysis and design. System testing, and testability, also changed as more system elements can now be measured than in traditional ... -
The utility of shared access licences for private wireless access networks
(North-West University (South Africa)., 2023)The increasing need for available spectrum has innovated development towards spectrum sharing techniques that allow shared access to be commercialised and used for private networks based on Long-term evolution (LTE). ... -
Traffic flow prediction with graph convolutional networks
(North-West University (South Africa)., 2023)Traffic flow prediction is a complex task utilising both spatial and temporal information in order to predict the expected speed of traffic at different points in a transportation network. We study the use of graph ... -
Channel estimation and equalisation using generative adversarial networks
(North-West University (South Africa)., 2023)Channel State Information (CSI) estimators are used in everyday communication systems to estimate channel impairments that affect transmitted data, and to equalise the impaired data to a more accurate state. However, ... -
Centralised vs decentralised PI control for an islanded multi-inverter microgrid
(North-West University (South Africa)., 2023)Energy supply security is arguably one of the most pressing challenges for both emerging and established countries around the world, as technology grows increasingly reliant on reliable energy. With the increase of ... -
Characterization of lignosulphonate and its changes during purification
(North-West University (South Africa)., 2023)The world needs an environmentally friendly renewable resource that could satisfy future energy needs and lower the impact on climate change. This need has driven many countries to fund research into biomass and biomass ... -
Effective removal of ammonia from the drinking water system : a case study at Magalies Water
(North-West University (South Africa)., 2023)Access to clean drinking water and sanitation is recognised as a human right and imperative to holistic functioning of life and interlocking nitty-gritties. In recent years, the quality of surface water in low- and ... -
Evaluation and modelling of particle collection efficiency of electrostatic precipitation
(North-West University (South Africa)., 2023)Many South-African power plants use wire-plate electrostatic precipitators (ESPs); however, these ESPs, in practice, have yet to meet the expected high particle collection efficiencies and present relatively low collection ...
