Investigation into the effect of Peel Ply surface preparation on adhesive bond performance
(2020)An adhesive joint’s strength is directly proportional to the quality of its bonding surface. One element influencing the quality of the bonding surface is the surface preparation before adhesive application. There are ... -
In-situ biodiesel production using liquefaction and supercritical extraction
(North-West University (South Africa), 2016)Biodiesel is an alternative source of energy with the potential to replace diesel fossil fuel. Full scale production however, has been hampered by high production costs since the extraction of oil causes excessive losses ... -
An integrated methodology to measure and verify energy conservation under incentive-based irrigation pumping programmes
(North-West University (South Africa), 2019)Water scarcity and droughts have become a looming threat in many counties worldwide. In South Africa, a water crisis is upon the country and estimations show a supply shortfall of 17% by 2030. When considering water ... -
Environmental data management for gold mines
(North-West University (South Africa), 2017)South Africa has various environmental concerns that escalate every year. For this reason, mines need to operate as effectively as possible. Millions of people can die due to water pollution, dangerous mining activities ... -
Design and Synthesis of a Robust Power Supply for Harsh Environments
(North-West University (South Africa), 2019)Research and control applications often takes place in harsh environments where equipment is exposed to less-than-ideal environmental conditions. This dissertation relies on a proven engineering process to design and ... -
Development of a micro burner for the experimental determination of the net calorific value at constant pressure of pulverised coal
(North-West University (South Africa), 2019)Coal combustion remains the major resource of power generation internationally. Coal consists of different substances, which influence its quality and properties. One such property is the calorific value (CV), which specifies ... -
Improving the operational efficiency of deep-level mine ventilation systems
(North-West University (South Africa), 2019)Deep-level mines are faced with many challenges that influence and affect the gold production rate. Deep-level mines have unfavourable working conditions due to the extreme depths, additional heat sources, confined spaces ... -
Methanol quality and its effects on the fuel-cell reformer off-gas composition
(North-West University (South Africa), 2019)Previous research articles that deal with methanol-steam reforming with Cu/ZnO/Al?O? catalyst do not take into account the quality of methanol used and the effect that it would have on catalyst performance and the off-gas ... -
Evaluation of key factors influencing a South African based electrical utility to utilise smart grid technologies for power quality management
(North-West University (South Africa), 2019)With the ever-growing global drive to reduce carbon emission compelling the need to diversify Energy generation options, solar and wind renewable energy sources are the popular choices in South Africa. Since photo-voltaic ... -
CFD airfoil profile drag calculation using far-field wake analysis
(North-West University (South Africa), 2019)With the ever increasing cost of experimental data and the ultimate decrease of project lifespan from design to implementation it has become the aerodynamicist?s main priority to design and model new ideas with precise ... -
Development of a Performance Management Tool for Patterson Grade B1-B3 employees at a minerals processing plant
(North-West University (South Africa), 2019)In this research a Performance Management Tool (PMT) has been developed from literature (primarily based on Locke and Latham's Goal-setting Theory) to assist supervisors in managing the performance of their lower level ... -
Critical success factor model to optimize power plant life cycle management
(North-West University (South Africa), 2019)For power utilities to secure a competitive edge in the energy sector, the efficiency of life cycle management programmes must be improved through successful execution of projects. In today's competitive environment, ... -
Industrialisation of underground coal gasification in South Africa and the commercial optimisation of the Theunissen UCG project
(North-West University (South Africa), 2019)South Africa faces long-term energy challenges, such as energy access and affordability; diminishing reserves of coal; environmental concerns; balancing the electricity grid whilst incorporating an increasing proportion ... -
Enhancing cross border operational efficiency with techno-social systems
(North-West University (South Africa), 2019)The emerging of global value chains means that, for a country or region to fully take advantage of this global phenomenon, then that country or region will need to be competitive in many areas of trade including trade ... -
Selection of suitable sub-models for improved confidence in lumped parameter internal ballistic codes
(North-West University (South Africa), 2019)Gun systems manufacturers, propellant manufacturers, ballisticians, and the users of gun systems heavily rely on interior ballistic simulations to describe projectile behavior from the initial point of propellant ignition ... -
