Comparison of physical properties of oxidative sintered pellets produced with UG2 or metallurgicalgrade South African chromite: a case study
(The Southern African Institute of Mining and Metallurgy, 2015)The physical properties of oxidative sintered pellets produced from typical South African UG2 ore are compared with the physical properties of pellets produced with conventional South African metallurgical-grade chromite ore ... -
A computer based assessment system for undergraduate electrical engineering modules
(SAIEE, 2013)Good assessment is an essential component of good learning. Marking test and exam papers for large classes is however a time-consuming and repetitive task. This paper reports on the design and implementation of a computer ... -
Condition monitoring of medium voltage electrical cables by means of partial discharge measurements
(SAIEE, 2014)The purpose of this paper is to discuss condition monitoring (CM) of medium voltage electrical cables by means of partial discharge (PD) measurements. Electrical cables are exposed to a variety of operational and ... -
The continuous depolymerization of filled polytetrafluoroethylene with a continuous process
(Wiley InterScience, 2008) -
Cooperative pair problem solving: a strategy for problem solving tutorials in the engineering sciences
(Tempus Publications, 2015)Engineering science courses, such as Thermodynamics, are often seen as difficult, and students have difficulty understanding the concepts and solving the problems. In an effort to improve the situation, we developed a ... -
Correlating hardware fault detection information from distributed control systems to isolate and diagnose a fault in pressurised water reactors
(ELSEVIER, 2013)Early fault identification systems enable detecting and diagnosing early onset faults or fault causes which allow maintenance planning on the equipment showing signs of deterioration or failure. This includes valve and ... -
A current analysis and correction system for vibration forces on the rotor of a rotating active magnetic bearing system
(SAIEE (South African Institute of Electrical Engineers), 2007)In this paper, an on-line detection, correction and identification system for vibration forces on the rotor of a rotating active magnetic bearing is proposed. The on-line detection system performs current analysis by ... -
Density functional theory molecular modelling and experimental particle kinetics for CO2–char gasification
(Elsevier, 2015)Experimental measurements and DFT atomistic modelling were conducted to elucidate the mechanisms for gasification chemistry of char with CO2 gas. The molecular models used were based on experimental representations of coal ... -
Design a thermoelectric cooling holder supplied by photovoltaic panels
(2015)In this paper, the development of a portable solar power vaccine carrier box for local usage in Africa and South Africa is described. The purpose is to provide guidance to the design of a thermoelectric cooling holder. An ... -
Design and cost analysis of an automation system for swimming pools
(EE Publishers, 2012)A low-cost automation system to minimise energy consumption of circulation pumps and to regulate the chemical composition of the water in swimming pools -
The design and development of a stented tissue mitral and aortic heart valve replacement for human implantation
(Clinics Cardive, 2012)A study was conducted into the development of a mitral and aortic heart valve replacement that caters for patients having suffered valve damage due to stenosis or rheumatic fever. The appeal of the valve is that it is ... -
Design and heat flow analysis of a commercial energy efficient in-line water heating system
(Multi-Science Publishing, 2014)In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ... -
Design of a prototype power line inspection robot
