Geo-tiles: manufacturing tiles from copper mine tailings using geopolymerisation by Makole, Karabo

“…Selection of IPU requirements as the QA benchmark for geo-tiles was made under the assumption that meeting the most stringent abrasion targets would indicate suitability for less severe situations. Requirements for IPUs only allow 0.3 cm3/cm2 of volumetric abrasion loss, with a maximum allowable abrasive depth of 3 mm. …”

The optimal placement of phasor measurement units and their effects on state estimation by Yuill, William

“…The two main objectives of this work are to investigate and develop 1. a method for the algorithmic placement of a minimum number of PMUs into a system to ensure full observability, 2. conventional, hybrid and linear state estimation techniques to incorporate and utilize PMU measurement data to perform state estimation and to study the effects that differing PMU placement positions have on the accuracy of the resultant state estimator solution.…”

Measuring cross-section data for prompt gammas emitted during proton-nucleus collisions by Ramanathan, Vijitha

“…Due to the fact that the treatment protons stop within the patient as they deliver the dose, secondary radiation is the potential method to obtain a dose verification measurement. …”

A granular flow model of an annular shear cell by Bremner, Sherry

“…The effect of two friction coefficients over a range of shearing wall velocities were examined in the DEM simulations. The data were examined over 3 selected radial lines and utilised to calculate the shear stress distribution and the power dissipation from the developed models. …”

Surfacing factors that prevent small businesses in economically deprived areas from growing: a multiple case study in Site C, Khayelitsha by Ncoliwe, Lwazi

“…Identifying these factors and understanding their dynamics can assist in developing strategies which will help in overcoming these challenges. The study utilised a multiple case study approach. Choosing businesses situated in the same geographical area ensured that certain external factors were held constant (for example, the socio-economic status of the surrounding community, distance from economic hubs, and crime levels), and therefore the use of multiple case studies allowed. …”

Developing a pathway out of poverty in the Global Coffee Production Network - a case study of employment creation for baristas in the speciality coffee industry by Anderson, Robyn

“…With a narrowly defined unemployment rate of 26.5% in South Africa, this paper contributes to the salient task of exploring a job creation programme in a high growth sector of the global coffee production network, namely the production of espresso based beverages by baristas for sale in restaurants, cafes, and hotels. Situated in the qualitative paradigm with an inductive research agenda, this research utilises the case study method to explore Ground UP, a skills training programme of a local not-for-profit, which provides barista skills training that unemployed people can use to become economically active in context of the specialty coffee industry. …”
