Linear model of a closed three-shaft Brayton cycle
(IEEE, 2004)A linear model of a closed three-shaft Brayton cycle is developed. The model is intended to give an understanding of the dominant dynamic behavior in a nuclear power system that utilizes a closed three-shaft Brayton cycle. ... -
Data acquisition system for capturing dynamic transients in a control valve
(IEEE, 2004)This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ... -
Status of international interconnections and electricity deregulation in Africa: an overview of the current status in Southern Africa
(IEEE, 2004)The Southern African power system is in a state of flux. The grid is expanding and more interconnections are being made. However, vastness of the area and the low power consumption density in most African countries makes ... -
Action evolution for intelligent agents
(IEEE, 2005)This paper introduces an alternative method of reinforcement learning for intelligent agents. The aim with this method is to closer emulate the natural thought processes of problem solving. This paper only provides a ... -
The global galerkin finite element method as applied to the 1d beam equation: a systems approach
(SAAM, 2006)The paper focuses on the finite element solution of the fourth-order differential for an EulerBernoulli beam. In this approach the point point loads and concentrated moments are treated in a natural way as part of the ... -
Email security awareness: a practical assessment of employee behaviour
(Springer, 2007)Email communication is growing as a main method for individuals and organizations to communicate. Sadly, this is also an emerging means of conducting crime in the cyber world, e.g. identity theft, virus attacks etc. ... -
A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ... -
Data mining: a technique used to extract information from tan delta measurements on medium voltage induction motors
(IEEE, 2007)The study attempted to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes were used to gain insight into the data and the condition of the insulation ... -
A qualitative assessment of the insulation systems of medium voltage induction motors
(IEEE, 2007)The research was an attempt to understand the condition of the insulation system and to classify the data according to its condition. Data mining processes was used to create a model to gain insight into the data and the ... -
Improving QoS for real-time multimedia traffic in ad-hoc networks with delay aware multi-path routing
(IEEE, 2008)A Mobile Ad-hoc Network (MANET) is a wireless network in which nodes, in the absence of fixed access points, communicate via single or multi-hop paths. Each node in a MANET should thus be able to perform necessary routing ... -
Regenerator for Varshamov-tenengolts-like synchronisation error correcting codes
(IEEE, 2008)Synchronisation errors, that is, the insertion of additional or deletion of valid symbols, are the most difficult class of errors to correct - containing the class of additive errors as a subset. A regenerating algorithm, ... -
Efficient packet erasure decoding by transforming the systematic generator matrix of an RS code
(IEEE, 2008)We consider the erasures-only decoding of Reed-Solomon codes. One class of erasure decoders of algebraic codes can be viewed as a transformation of the systematic generator matrix, as first noticed by Berlekamp. We extend ... -
On the development of a power quality benchmarking model
(IEEE, 2009)The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ... -
Towards PQ regulation in Southern Africa
(IEEE, 2009)This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective -
The application of modern technology in power quality management
(IEEE, 2009)Little business integration of power quality management (PQM) is forthcoming amongst electrical utilities all over Southern Africa. Restricted access to proper information is the main reason. A integration of tools, ... -
Issues in software development practices : A South African software practitioners’ viewpoint
(2009)Software development is a process tasked with the development of artefacts that are used to implement organizational information systems. Depending on the social, economical and environmental setting, different ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009) -
Using an effective viscosity to account for the effect of the walls on the pressure drop through an annular packed bed
(ASME, 2009)The question arose whether the correlation for the pressure drop prescribed for cylindrical pebble bed reactors by the Nuclear Safety Commission (KTA) of Germany could still be applied to the proposed annular configuration ... -
Accounting for porous structure in effective thermal conductivity calculations in a pebble bed reactor
(Atomic Energy Society of Japan, 2009) -
Evaluating methods to binarize historic cosmic-ray recordings
(IEEE, 2009)Three adaptive image binarization approaches are evaluated to find the method best suited for the binarization of historic cosmic-ray data. The methods are optimized by fine tuning their parameters and they are then ...
