Validating the integrity of single source condition monitoring data
(North-West University (South Africa), 2020)Vast amounts of data are generated daily and play an important role in decision-making and performance evaluation. Ill-informed decisions can have costly, negative effects. For this reason, confidence in the data used is ... -
Validation of popular nonsinusoidal power theories for the analysis and management of modern power systems
(North-West University, 2005)Non-sinusoidal conditions are characteristic of modem electrical power systems. Technological advances such as that of the rapidly developing solid-state technology has accelerated the nonlinear loading of power systems. ... -
Validation of the point kinetic neutronic model of the PBMR
(North-West University, 2007)This study introduces a new method for the validation of the point kinetic neutronic model of the PBMR. In this study the diffusion equation solution, as implemented in the TlNTE PBMR 268 MW reactor model, replaces the ... -
Value added utilisation possibilities of coal combustion products in South Africa
(North-West University, 2018)The disposal of coal combustion products (CCP's), which includes coal ash and the new combustion product Flue Gas Desulphurisation (FGD) gypsum, causes significant environmental and economic difficulties. Only a small ... -
The value of simulation models for mine DSM projects
(North-West University, 2012)Energy shortage, escalation of energy cost and climate change have led to an increased focus on energy conservation worldwide. In order to curb the increase in electricity demand, Eskom has introduced demand-side management ... -
A value-add driven report development framework for mining industries
(North-West University (South Africa)., 2021)The South African mining industry is vital to the country’s economy, but it is under pressure to remain profitable and sustainable. Although many studies have focussed on how to optimise mining operations, they have used ... -
A variable water flow strategy for energy savings in large cooling systems
(North-West University, 2013)Large cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water and cool ventilation air. Improving ... -
Variance reduction techniques for MCNP applied to PBMR
(North-West University, 2009)The applicability of the Monte Carlo N-Particle code (MCNP) to evaluate reactor shielding applications is greatly improved through the use of variance reduction techniques. This study deals with the analysis of variance ... -
Vehicle vibration analysis
(North-West University (South Africa)., 2014)Engine noise and vibration harshness is a big concern in the competitive automotive vehicle manufacturing industry. It is very important to limit the vibration and noise levels for the general pleasure of driving. Vibration ... -
Verification of leakage through the side reflector graphite of the PBMR reactor
(North-West University, 2004)As a result of manufacturing and temperature constraints of the reactor core components, leakage flow is an inevitable, and generally undesirable, occurrence within the PBMR reactor. Leakage flow occurs between the narrow ... -
Verification procedures to ensure consistent energy measurements
(2014)The majority of energy conservation measures (ECM) implemented by South African Energy Service Companies (ESCOs), are funded by the Eskom Demand Side Management (DSM) initiative. In 2013 Eskom reported a total DSM savings ... -
Viability of 3D fused filament fabrication for aerospace applications
(North-West University (South Africa), 2021)This study investigates the possible utilization of modern three-dimensional (3D) fused filament fabrication (FFF) in engineering applications. These FFF machines use filament that are usually made from PLA or ABS, coiled ... -
Vibration characterization of an active magnetic bearing supported rotor
(North-West University, 2011)The McTronX Research group at the Potchefstroom campus of the North-West University, aims to establish a knowledge base on active magnetic bearing (AMB) systems. Up to date, the group has established a firm knowledge base ... -
Vibration isolation of dimple plate heat exchangers
(North-West University, 2012)Dimple plate heat exchangers are a new type of welded compact plate heat exchangers. The dimple plates increase the turbulence of the fluid flowing over the plate, increasing the efficiency of the heat exchanger without ... -
Virtual mobility in tertiary education : the impact of ICT based communication on learning
(North-West University, 2007)Background and rationale for the research As the world becomes more of a global village, people are faced with different challenges. Some of these challenges include the globalisation of business and of the workforce. This ... -
A voltage dip management program for Swaziland
(North-West University, 2019)The importance of Power Quality (PQ) is recognised by governments internationally to such an extent that in non-competitive electricity markets such as Southern Africa, it is required by law that the supplier of electricity ... -
Volume weighted interpolation for unstructured meshes in the finite volume method
(North-West University, 2005)The finite volume method is widely used for the numerical simulation of fluid flow because of its rigorous local conservation properties and its compatibility with arbitrary unstructured meshes for meshing complex domains. ... -
Wastewater remediation using municipal solid waste-derived hydrochar
(North-West University (South Africa)., 2023)Industrialisation and population growth increase solid waste generation and the release of toxic pollutants into the environment. Therefore, novel approaches are necessary for both wastewater remediation and solid waste ... -
Water balance development for legal compliance of gold mines in South Africa
(North-West University (South Africa)., 2022)South Africa is experiencing water scarcity due to the increase in water demand and decrease in water supply. A predicted shortfall of 17% by 2030 is prompting stricter enforcement of the National Water Act number 36 of ... -
Water minimisation at the power station using process integration
(North-West University, 2019)The primary objective of this study is to determine the reduction of the raw water intake of an existing power station by applying process integration techniques to optimise the use of water available in the system. The ...
