The effect of particle size on the performance of low-smoke fuels in coal stoves
(North-West University, Potchefstroom Campus, 2018)
The link between exposure to household air pollution (HAP) and ill-health has been consistently
drawn in the literature. The World Health Organisation (WHO) places the burden of disease
from HAP at an estimated 4.3 million ...
Reconfiguring mine water reticulation systems for cost savings
(North-West University, Potchefstroom Campus, 2018)
Rising electricity costs in South Africa force companies, including gold mines, to minimise their
energy consumption (EC). More than 30% of the total energy demand for deep-level mines is
consumed by the water reticulation ...
Preparation of polyurethane foam from lignin and crude glycerol
(North-West University (South Africa), Potchefstroom Campus, 2018)
The development and implementation of lignocellulose-based biorefineries which produce renewable fuels, chemicals and pharmaceuticals are expected to grow, but still face technological challenges. Economic feasibility could ...
Condition based reliability simulator for power stations
(North-West University (South Africa). Potchefstroom Campus, 2018)
The SA Power Utility operates 27 power stations with a total nominal capacity of 41,995 MW, comprising 35,726 MW of coal-fired stations, 1,860 MW of nuclear, 2,409 MW of gas–fired, 2,000 MW hydro and pumped–storage stations ...
Simulating operational improvements on mine compressed air systems
(North-West University (South Africa). Potchefstroom Campus, 2018)
As the operational costs of deep-level mines increase and gold ore grades decrease, profitability
in the South African gold mining sector is becoming a challenge. Electricity tariff increases
moreover contribute to the ...
Expanding industrial thinking by formalizing the industrial engineering identity for the knowledge era
(North-West University, 2018)
This PhD study provides a multi-perspective view of Industrial Thinking and the Industrial Engineering profession. The aim is to formalize the Industrial Engineering identity and expand its associated thinking style to ...
An integrated software platform for the efficient management of projects
(North-West University, 2018)
Electronic software platforms play a role in the internal processes and management of projectbased firms. Many task-based solutions exist in practice to handle projects e ciently. These tools address shortcomings that ...
Modelling and efficiency improvement of a plasma-arc gasification reactor quench probe
(North-West University, 2018)
A steady state computational fluid dynamics (CFD) model was developed to describe the temperature and flow characteristics inside a laboratory scale plasma-arc gasification reactor quench probe with the aim of efficiency ...
Comparative study of mine dewatering control systems
(North-West University, 2018)
Deep-level mines use a series of dams and pumps known as a dewatering system to remove water from underground. The dewatering process can be automated and then controlled on different levels in the control system: programmable ...
Analysis of TV White Space using a Spectrum Observatory
(North-West University, 2018)
The concept of Dynamic Spectrum Access (DSA) allows the under-utilised spectrum to be made available for Secondary Users (SUs) on condition that such SUs do not cause harmful interference for the Primary User (PU). The ...
