A systems engineering approach to coronary heart disease
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Coronary heart disease (CHD) is the largest cause of death globally. This is worrying considering the substantial investments made in the research and prevention of CHD. It may be possible that the current reductionistic ...
Economic feasibility of a pre-oxidative process to enhance solid-state chromite reduction
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Chromite ore mining is the only commercially viable source of new chromium (Cr) units. South Africa (RSA) holds the majority, approximately 75%, of the world’s exploitable chromite ore resources. The vast majority of mined ...
The use and effectiveness of project management methodologies in mobile application development
(2015)
This study aims to fill the gap in managing mobile applications with certain project
management methodologies (PMM) by looking at different kinds of PMMs and
comparing them to characteristics of mobile applications.
To ...
Investigating the feasibility of braking energy utilisation on diesel electric locomotives for South African Railway Duty Cycles
(2015)
Five modes of transport exist on earth; 1) road, 2) sea, 3) rail, 4) air, and 5) pipeline. Railways have been used for centuries as a means of terrestrial bulk transportation due to its inherent low cost per tonne. ...
Quality management system to improve conveyor system performance : Lethabo Power Station as case study
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Eskom Lethabo Power Station experienced a number of ash plant conveyor failures that resulted in production loss and plant damages. This study was aimed at determining the root causes of the failures (technical, management ...
A structured approach to select energy efficiency incentives applicable to industry
(North-West University (South Africa) , Potchefstroom Campus, 2015)
In recent years, energy efficiency has grown significantly in importance. Energy efficiency improvements are among the most cost effective ways to reduce energy consumption and CO2 emissions. Measures such as policies, ...
Ash resistivity profiling and effect of a high frequency power supply on electrostatic precipitator efficiency
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Particulate emissions of coal-fired power stations are governed by the air quality legislation as stipulated by the Department of Environmental Affairs. The legislation stipulates the amount of particulate emission a ...
Investigating the effect of pump availability on load shift performance
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Due to the high electricity consumption trends of pumping operations in the mining sector, numerous load-shifting projects have been implemented to reduce peak TOU demand for electricity. A lack of maintenance on pump ...
Cathodic protection system design framework for the petrochemical industry
(North-West University (South Africa) , Potchefstroom Campus, 2015)
The aim is to establish a cathodic protection (CP) system design framework for the petrochemical industry in South Africa. The CP system design framework is destined to be used as a guideline when designing CP systems for ...
A heterogeneous Thorium-based fuel design for a PWR aimed at increasing fuel cycle length
(2015)
A new heterogeneous Thorium based fuel design has been proposed for Pressurised Water Reactors in order to increase fuel cycle lengths. This design incorporates ThO2 pellets which have been included between UO2 fuel pellets ...
