The identification and application of a method to test chloride ingress into concrete, sulphur-concrete and sulphur-cement coated concrete
(North-West University (South Africa) , Potchefstroom Campus, 2017)Concrete is the main material used for the construction of civil structures in industry. Concrete is also used in the construction of nuclear power plant civil structures (e.g. the containment building). Concrete ages but ... -
Identification model for cost-effective electricity savings on a mine cooling system
(North-West University, 2018)South Africa has the world's largest reserve of platinum and gold. Despite this, the mining sector is struggling to stay economically viable. Increased costs in mining are one of the main contributors to the struggle of ... -
Identification of cellular handsets through radio frequency signature extraction on an FPGA platform
(2015)Specific emitter identification refers to the process of performing identification of radio frequency transmitters by exploiting unique variations in emitted signals, caused by hardware variations. In previous research, ... -
Identifying demand market participation opportunities available in cement plants
(2014)South African cement manufacturers are under financial pressure. Sales have declined due to the 2008 recession and electricity costs have tripled from 2005 to 2012. Electricity cost savings are therefore more important ... -
Identifying essential data to evaluate and monitor energy performance
(North-West University (South Africa), 2021)The quantification of energy efficiency projects on a company’s energy footprint are important. Energy management projects previously monitored energy consumption by using a ring-fenced approach. Though energy management ... -
Impact assessment of the environmental protection policies in the upstream oil industry in Nigeria
(North-West University, 2011)The need for energy and the associated economic benefits from the oil and gas deposits found mainly in the Niger Delta region of Nigeria necessitated the exploration and exploitation activities being carried out by the ... -
Impact of beryllium reflector ageing on Safari–1 reactor core parameters
(North-West University, 2011)The build–up of 6Li and 3He, that is, the strong thermal neutron absorbers or the so called "neutron poisons", in the beryllium reflector changes the physical characteristics of the reactor, such as reactivity, neutron ... -
The impact of current transformers on measurement uncertainty of power quality
(North-West University, 2019)The impact of current transformer accuracy on the uncertainty of harmonic measurements was investigated. A literature review revealed the lack of traceability of harmonic measurements conducted using IEC 61869-2 or IEC ... -
Impact of energy efficiency and renewable energy on electricity master planning and design parameters
(North-West University (South Africa) , Potchefstroom Campus, 2017)At the core of network planning and designs, after diversity maximum demand (ADMD) is routinely used to define network conditions at peak periods. This dissertation explores the impact of distributed generation and energy ... -
The impact of homogenized cross-section correction mechanisms in OSCAR-4 as applied to SAFARI-1 research reactor
(North-West University, 2019)The nodal solver OSCAR-4 reactor analysis system contains a series of approximations (nonlinear extensions) which aim to correct the full-core nodal calculation (mostly via corrections to the homogenised cross-sections) ... -
Impact of the telecommunication industry on the socio-economic life of Nigerians : Okata area of Lagos as case study
(North-West University, 2009)The research study investigates the impact of the telecommunication industry on the socio-economic lives of Nigerians. The Nigerians residing in Okata area of Lagos were taken as case study. 300 samples were selected at ... -
Impact of voltage waveform quality on distribution network planning
(North-West University, 2018)The present study investigated the power losses in a specific portion of the MV distribution network in Potchefstroom, South Africa. This was done in an attempt to assess and predict the impact of harmonic distortion on ... -
Implementation and evaluation of V/f and vector control in high–speed PMSM drives
(North-West University, 2011)The McTronX research group, at the Potchefstroom campus of the North–West University, has been researching Active Magnetic Bearings (AMBs). A fully suspended, flywheel energy storage system (FESS) has been developed. Due ... -
The implementation of a dynamic air compressor selector system in mines
(2015)The generation of compressed air comprises 20% of the total electricity usage in the mining industry, although compressed air is often seen as a free source of energy. There are however significant costs associated with ... -
Implementation of membrane technology in a base metal refinery
(2013)In this study, the implementation of membrane technology at Anglo Platinum’s base metals refinery to separate acid from metal containing solutions was investigated. The refinery includes a circuit known as the “sulphur ... -
An implementation strategy for Tecnomatix Plant Simulation software
(North-West University (South Africa)., 2022)Many companies are investigating on whether it would be beneficial (financially and operationally) to implement discrete-event simulation (DES) software in-house. Moreover, to what strategy can be followed in implementing ... -
Implementing a distributed approach for speech resource and system development
(2014)The range of applications for high-quality automatic speech recognition (ASR) systems has grown dramatically with the advent of smart phones, in which speech recognition can greatly enhance the user experience. Currently, ... -
Implementing a remote condition monitoring system for South African gold mines
(North-West University (South Africa), 2019)In a modern world, people and industries are increasingly using technology to automate and optimise systems and processes. This also applies to the field of condition monitoring on any level. Several recent academic studies ... -
Implementing DSM interventions on water reticulation systems of marginal deep level mines
