• Design of a prototype power line inspection robot ﻿

(2013)
The purpose of this paper is to provide the design of a prototype power line inspection robot for the monitoring of Eskom transmission lines. It should also determine if an inspection robot would be a feasible solution ...
• Design of a prototype ultra-capacitor solar panel street light ﻿

(2013)
The purpose of the paper is to describe and discuss the design of a prototype ultracapacitor solar panel street light. The effect of ultra-capacitors as an energy storage device in a solar panel street light is evaluated. ...
• Design of a transmission line monitoring solution for an unmanned quadcopter ﻿

(2014)
Eskom owns thousands of kilometres of transmission lines that need to be inspected in order to plan maintenance. Current methods of inspection are costly and ineffective and could pose safety risks. Systems already developed ...

• A detailed calculation of neutral hydrogen ionization frequencies used in turbulence transport models in the heliosphere ﻿

(EDP Sciences, 2015)
It is generally accepted that the solar wind is significantly heated beyond ~10 AU by the turbulent decay of pickup ion generated Alfvénic fluctuations. Here, we present a detailed and general calculation of the pickup ion ...
• Detailed characterization of SA high mineral matter inertinite–rich coals and density fractions and effect on reaction rates with carbon dioxide:  macerals, microlithotypes, carbominerites and minerals ﻿

(South African Institution of Chemical Engineers (SAIChE), 2013)
An investigation was undertaken to determine the distribution of macerals and minerals in South African Highveld coal deposits as well as density fractions derived from a typical deposit. The corresponding effects on ...
• The detailed nature of active central cluster galaxies ﻿

(Oxford University Press, 2013)
We present detailed integral field unit observations of the central few kiloparsecs of the ionized nebulae surrounding four active central cluster galaxies (CCGs) in cooling flow clusters (Abell 0496, 0780, 1644 and ...
