Karakterisering en evaluering van 'n hidrouliese enjinmonteerstuk
(North-West University, 2011)The engine mount system is an important aspect to achieve vibration isolation, and has a very important effect on the ride standards and noise in a vehicle's compartment. In this study a hydraulic engine mount was designed ... -
Knowledge discovery with additive attribution methods for geomagnetic index prediction
(North-West University (South Africa)., 2023-10)During a solar cycle, the Sun emits various ejections such as Coronal Mass Ejections (CME) and higher-pressure streams caused by Corotating Interaction Regions (CIR). These ejections induce geomagnetic storms that are known ... -
Knowledge management within an organisation: A consulting engineering company as a case study
(North-West University (South Africa), 2020)Knowledge is power. Knowledge management (KM) provides comprehensive means to channel this potential power to the benefit of an organisation. When flourishing in an enterprise, KM offers substantial benefits which includes ... -
The Lattice Boltzmann Method applied to linear particle transport
(North-West University, 2012)In this study, the applicability of the Lattice Boltzmann Method to neutron transport is investigated. The transport model used, is derived from the Boltzmann equation for neutral particles by inverting the streaming ... -
Leachability of polycyclic aromatic hydrocarbons from coal tar and synthesis of the nanohybrid photocatalyst for their degradation
(North-West University (South Africa), 2021)There exists a great number of industrial processes that produce coal tar as a by-product. The rate of coal tar production is higher than the rate at which it is converted to other products, and its application is very ... -
The leaching behaviour of a Ni–Cu–Co sulphide ore in an oxidative pressure–acid medium
(Potchefstroom University for Christian Higher Education, 2001)Hydrometallurgical processing of sulphide concentrates is an attractive method for the selective extraction of valuable metals. The dissolution of minerals in a leaching process involves several electrochemical parameters ... -
Leaching kinetics of carbonatite and silicate based chalcopyrite minerals
(North-West University (South Africa), 2020)Copper (Cu) is a widely used metal with high thermal and electrical conductivities, which is primarily extracted from the low-grade Cu sulphide mineral, chalcopyrite. Hydrothermal extraction is the preferred process for ... -
A Lean implementation framework encompassing South African Ubuntu
(North-West University (South Africa)., 2022)Lean, a management philosophy originating from Toyota, is used to eradicate wastes and increase efficiency within an organisation. Even though Lean philosophy has become a global phenomenon, only about 10% of the ... -
A lean project management framework for additive manufacturing
(North-West University (South Africa), 2019)This study aims to present a lean project management framework for the additive manufacturing industry (AM). This framework will contain critical elements of project management (PM) and will intend to add value to an ... -
Lecture transcription systems in resource–scarce environments
(North-West University, 2014)Classroom note taking is a fundamental task performed by learners on a daily basis. These notes provide learners with valuable offline study material, especially in the case of more difficult subjects. The use of class ... -
Leveraging Software-Defined Networking for QoS in home networks
(North-West University (South Africa), 2019)Home networks refer to devices at the edge of the internet. These networks face unique provisioning challenges. As the home network is growing and more complex devices are added, the Internet Service Provider (ISP) may ... -
A licensing plan for coupling a nuclear energy source to a chemical process plant : SASOL Secunda as a case study
(2014)The purpose of the research study was to identify the implications of the licensing processrelated costs for coupling high temperature reactor(s) (HTR) to the SASOL coal-to-liquid (CTL) process (hereafter known as nuclear ... -
Life-extension in a research reactor: calculation of the neutron-induced ageing of the core-box, grid-plate and beryllium reflector
(North-West University (South Africa), 2019)The SAFARl-1 research reactor has been operating at NECSA- the South African Nuclear Energy Corporation - since 1965. SAFARI-1 is a tank-in-pool type research reactor of similar design to the original Oak Ridge Materials ... -
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 ... -

Liquefaction of sunflower husks for biochar production
(2014)Biochar, a carbon-rich and a potential solid biofuel, is produced during the liquefaction of biomass. Biochar can be combusted for heat and power, gasified, activated for adsorption applications, or applied to soils as a ... -
Load management on a municipal water treatment plant
(2015)Water Treatment Plants (WTPs) supply potable water which is transferred by pumps to various end users. WTPs and other sub-systems are energy intensive with pump installed capacities varying between 75 kW – 6 000 kW. It has ... -
Load management through the utilisation of VSDs on water transfer schemes
(North-West University (South Africa) , Potchefstroom Campus, 2017)South Africa is a water scarce country and due to this, large water transfer schemes were built to supply major parts of the country with raw and potable water. The Department of Water and Sanitation directly control some ... -
Load shift through optimal control of complex underground rock winders
(North-West University, 2009)South Africa's national power utility, Eskom, initiated a Demand Side Management (DSM) drive to help alleviate the electricity supply shortage experienced in South Africa. The focus of this study is on a load-shifting ... -
Local content development in the Nigerian oil and gas industry : why it is not succeeding?
(North-West University, 2008)This research focuses on human capacity development in the Nigerian oil and gas industry. The need for local capacity building in this industry is imperative because oil and gas proceeds are the major source of foreign ...
