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 ... -
Export market selection methods and the identification of realistic export opportunities for South Africa using a decision support model
(2009)Market selection methods, of which a vast number exist, are a critical tool in firms’ and government’s policy, planning and budgeting processes. To this end, the primary aim of this paper is to determine the international ... -
Unraveling the emission geometry of the Fermi millisecond pulsars
(Fermi, 2009)The nine millisecond pulsars (MSPs) that have now been detected by Fermi-LAT are providing an excellent opportunity to probe the emission geometry of these ancient compact objects. As they are radio-loud, one may use the ... -
Modeling of gamma-ray millisecond pulsar light curves revealed by Fermi-LAT
(Thê Giói Publishers, 2009)Fermi Large Area Telescope (LAT) has recently detected 8 gamma-ray millisecond pulsars (MSPs), providing an unprecedented opportunity to probe the magnetospheres of these lowspin-down pulsars. We performed 3D emission ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ... -
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)A proper understanding of the mechanisms of heat transfer, flow and pressure drop through a packed bed of spheres is of utmost importance in the design of a high temperature pebble bed reactor. A thorough knowledge of the ... -
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 ... -
Considerations in Grounded Theory Research Method: A reflection on the lessons learned
(2010)This paper is a discussion on the practical issues faced by Information Systems (IS) professionals when they employ Grounded Theory Method (GTM) in Information Systems research. Various strands of GTM are in use, all of ... -
An ontology-driven software development framework
(2010)The software development process has been curtailed by the lack of a methodology that can capture and maintain the softer, humanist characteristics of organizational systems into the software product. This is attributed ... -
Ontology goes postmodern in ICT
(ACM Press, 2010)This paper investigates the move from philosophical ontology to information systems ontologies. Ontology has traditionally been (and still is) a philosophical discipline that studies the nature of existence. In a certain ... -
Delevitation modelling of an active magnetic bearing supported rotor
(s.nCurran Associates, 2010)For active magnetic bearings (AMBs) to be used with confidence in industrial applications, the safe failure of the AMB system should be guaranteed. The exact behaviour of the rotor on the backup bearings (BBs) is relatively ... -
The mutualistic relationship between information systems and the humanities
(IBIMA, 2010)The paper explores the nature of the relationship between the study fields of Information Systems and the humanities. Although literature on Humanities Computing states in principle that there is a bidirectional, beneficial ... -
Guidelines for the design and creation of a web form to facilitate the registration of first time tax payers: an HCI approach
(IBIMA, 2010)Research has been conducted both in the field of Human-Computer Interaction and in the field of design and creation. Very little research has been conducted in the area of tax registration systems. No research was carried ... -
The role of an ICT research professor in South Africa
(Sprouts Alliance, 2010)Until recently it has been assumed that all lecturers at tertiary institutions should teach, conduct research and do community service. Due to heavy teaching loads, this assumption has become evident as a very idealistic ... -
The use of an information security vocabulary test to assess information security awareness: an exploratory study
(Centre for Security, Communications and Network Research (CSCAN), 2010)The dependence on human involvement and human behavior to protect information assets makes it necessary to have an information security awareness program to make people aware of their roles and responsibilities towards ... -
The practice of applicability checks in information systems research: an empirical confirmation
(WSEAS, 2010)The practice of applicability checks1 can be considered a relative new concept in the field of Information Systems (IS) research. It is, however, an appropriate method to ensure the practical relevance of research. The ...
