Integrating innovation skills in an introductory engineering design-build course

Liebenberg, Leon; Mathews, Edward Henry (Spring, 2010)
Introduction to the PBMR heat transfer test facility

van Staden, M (Elsevier Science Limited, 2008)
Investigating leakage and bypass flows in an HTR using a CFD methodology

Kleingeld, Marius; Janse van Rensburg, Jacobus Johannes (Elsevier, 2011)

An area that has been identified as significantly important in the development of a high temperature reactor (HTR) is the prediction of leakage and bypass flows. It is therefore essential to understand the influence of ...
Investigation of lump coal agglomeration in a non-pressurized reactor

Bunt, John Reginald; Campbell, Quentin Peter; De Waal, F (Elsevier, 2010)
A kinetic expression for the pyrolytic decomposition of polyterafluoroethylene

Bruinsma, Odolphus S L; Neomagus, Hendrik W J P; Van der Walt, I J; Nel, J T; Crouse, P L (Elsevier Science Limited, 2008)
LTI modelling of active magnetic bearings by means of system identification

Van Schoor, George; Van Vuuren, Pieter Andries; Venter, Willem Christiaan (SAIEE Publications, 2011)

A relatively unknown phenomenon in active magnetic bearings (AMBs) is that the frequency content of their rotor position signal can induce nonlinear behaviour in the bearings. The existence of such frequency-induced nonlinear ...
Manipulation of gasification coal feed in order to increase the ash fusion temperature of the coal enabling the gasifiers to operate at higher temperatures

Waanders, Frans B; Van Dyk, J C (Elsevier Science Limited, 2007)
Manipulation of the ash flow temperature and viscosity of a carbonaceous Sasol waste stream

Waanders, Frans Boudewijn (Elsevier, 2010)
Measurement and verification of a lighting load reduction project through energy efficiency

Van Der Merwe, Christoffel; Masopoga, Idah; Grobler, Louis J (2009)

This paper will describe the methodology and procedures that were followed to measure and verify the impact on the electricity use of a lighting load reduction project implemented at a gold mine. The lighting retrofit ...
Multiple frequency fault detection, correction and identification of vibration forces on the rotor of a rotational active magnetic bearing system

Van Schoor, George; Gouws, Rupert (School of Electrical, Electronic and Computer Engineering, North-West University, 2009)
Multivariable H∞ or Centre of gravity PD control for an active magnetic bearing flywheel system

Steyn, Stephanus Jacobus Marais; Van Schoor, George; Van Vuuren, Pieter Andries (SAIEE Publications, 2011)

A state-space model with uncertainties for an active magnetic bearing energy storage flywheel system (Fly-UPS) is developed. A multivariable robust H∞ controller for the Fly-UPS is then synthesised. Different weighting ...
A new and innovative look at anti-insulation behaviour in building energy consumption

Grobler, Louis; Masoso, Okatoseng Tsametse (Elsevier Science Limited, 2008)
A new approach to ensure successful implementation of sustainable demand side management (DSM) in South African mines

Mathews, Edward H; Kleingeld, Marius; Pelzer, Ruaan; Le Roux, D.F. (Elsevier Science Limited, 2008)
A new model to estimate Bolus Insulin Need

Mathews, Edward H; Pelzer, Ruaan (Mary Ann Liebert, Inc, 2009)

Patients with type 1 diabetes usually use the carbohydrate (CHO) counting method to establish their bolus insulin need. However, most still struggle with blood glucose control. We believe that for good control their insulin ...
Object-oriented embedded C

Van Schoor, George; Neser, Morne (School of Electrical, Electronic and Computer Engineering, North-West University, South Africa, 2009)

This paper presents an object-oriented implementation of ANSI-C for embedded systems. It offers practical guidelines for producing generic software libraries and portable applications. While various object-oriented ...
On systematic generator matrices for Reed-Solomon codes

Ferreira, Hendrik H H; Helberg, Albertus Stephanus Jacobus; Ridley, James J; Versfeld, Daniel D D (IEEE Information Theory Society, 2010)
Optimal power control of a three-shaft brayton cycle based power conversion unit

Uren, Kenneth Richard; Van Niekerk, Casparus Rynhardt; Van Schoor, George (Gardenview [South Africa] : SAIEE Publications, 2010)
Optimisation of a storage facility used to effect power control in the PBMR power cycle

Mathews, Edward A; Pelzer, Ruaan; Matimba, A (The South African Institution of Mechanical Engineering (SAIMechE), 2008)

This article presents the optimization of a gas storage facility used to effect power control in South Africa's PBMR power cycle. It was shown in the article, a multitank storage facility to affect power control in the ...
Pebble Bed Micro Model system identification

Venter, Willem Christiaan; Lamprecht, E.C. (Elsevier, 2012)

Linear system identiﬁcation techniques will be applied to obtain mathematical models of a simulation of the Pebble Bed Micro Model (PBMM). The PBMM is a conceptual model of the Pebble Bed Modular Reactor (PBMR), a new high ...
The petrographic determination of reactivity differences of two South African inertinite-rich lump coals

Malumbazo, N.; Wagner, N.J.; Bunt, J.R. (Elsevier, 2012)

There is limited literature on the classification and characterization of chars generated from lump coals during synthesis gas production, especially from a South African perspective. Two inertinite-rich medium rank C ...
