Morphological segmentation of isiXhosa using unsupervised machine learning
(North-West University (South Africa), 2021)
In this work the use of unsupervised machine learning in the morphological segmentation of Nguni languages, evaluated on isiXhosa, is advanced. The work researches, extends, implements and evaluates unsupervised machine ...
Evaluation of perhydrodibenzyltoluene dehydrogenation parameters and durability using noble metal catalysts for hydrogen production
(North-West University (South Africa), 2021)
Hydrogen storage using liquid organic hydrogen carrier (LOHC) technology offers numerous advantages over conventional hydrogen storage systems. LOHCs are organic compounds that can store and release hydrogen through catalytic ...
Design methodology for the Levelok conveyance arresting system used in the mining industry
(North-West University (South Africa), 2021)
Proceeds from gold and diamond mining operations make a significant contribution to the South
African economy, and therefore deep-level mining has become widely practiced throughout the
country. Six of the ten deepest ...
Limitations of current cooling water treatment processes to control cooling water chemistry in wet cooled power plants
(North-West University (South Africa), 2021)
In a coal-fired power plant, recirculating cooling water exchanges latent heat energy with the exhaust steam in the condenser and transports the heat to the cooling tower for evaporative cooling. The water lost in the ...
Modifying software systems to improve user adoption
(North-West University (South Africa), 2021)
Industry 4.0 has driven the digitisation of large scale industrial and mining operations. This
introduced the burden of large volumes of data to process. Data from industrial systems is usually
processed by specialised ...
Design and evaluation of a vibration ore flow restore machine
(North-West University (South Africa), 2021)
Ore passes provide a low cost method for gravitational transport of broken ore and waste rock through long vertical distances to lower levels of an underground mine. A hang-up or blockage in an ore pass is undesirable as ...
The development of autothermal microchannel reactor technology for hydrogen-based gas processing
(North-West University (South Africa), 2021)
Key challenges associated with the production, transport, storage and continuous use of
hydrogen (H₂), generated from renewable energy, is the natural intermittency of some
renewable resources such as solar photovoltaic ...
Carbon dioxide capture from flue gases using dry sorbents
(North-West University (South Africa), 2021)
The project entails capturing CO₂ produced from industrial flue gases with dry adsorbents through gas adsorption to mitigate the CO₂ emissions. Four commercially available activated carbon samples (CQ006, CQ30P, CQ650 and ...
Mapping the job potential of the industrial engineer: a web-investigation
(North-West University (South Africa), 2021)
The industrial engineering discipline is inherently interdisciplinary and broad, with many areas of specialization. It interfaces with both the hard sciences and the soft sciences to solve a wide variety of problems in all ...
Development of a strategic decision-making model for the South African nuclear sector
(North-West University (South Africa), 2021)
The main objective of this research study was to develop a strategic decision-making model for the South African (SA) nuclear sector in response to lack of expansion. Since 1994, this lack of growth was marked by two ...
