An integrated self-sensing approach for active magnetic bearings

Ranft, Eugen Otto; Van Schoor, George; Du Rand, Carel Petrus (SAIEE Publications, 2011)

Self-sensing permits active magnetic bearings (AMBs) to consolidate the actuation and sensing functions into a single electromagnetic transducer. Eliminating the position sensing device as well as interfacing reduce potential ...
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 ...
Modeling the flow and heat transfer in a packed bed high temperature gas-cooled reactor in the context of a systems CFD approach

Du Toit, C.G.; Rousseau, P.G. (ASME (American Society of Mechanical Engineers), 2012)

ABSTRACT Engineers are faced with two major challenges when carrying out the thermal-fluid design of a complex system consisting of many interacting components. The first challenge is to predict the performance of all the ...
Modified earliest decoding in networks that implement random linear network coding

Helberg, Albertus Stephanus Jacobus; Von, Solms Sun? (2012)
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)
