Theoretical and practical aspects of Cr(VI) in the South African ferrochrome industry
(SAIMM, 2010)The production of ferrochrome alloy from chromium bearing chromite ores is conducted at high temperature under highly reducing conditions. However, albeit completely unintended, it is impossible to completely exclude ... -
A quantitative model to evaluate post-implementation efficiency of Scrum
(IOS Press, 2010)In order to improve the information system development process many companies have adopted system development methodologies. Various evaluation methods and frameworks exist in the literature to assist companies during their ... -
Bioethanol from cassava for a community project
(ETA-Florence Renewable Energies, 2010)Although the North-West Province of South Africa is renowned for its platinum industry, wildlife tourism and Casino resorts, its people are among the poorest in South Africa. The Thusanang community project concept was ... -
Gamma-ray and radio properties of six pulsars detected by the Fermi Large Area Telescope
(IOP, 2010)We report the detection of pulsed γ-rays for PSRs J0631+1036, J0659+1414, J0742-2822, J1420-6048, J1509-5850, and J1718-3825 using the Large Area Telescope on board the Fermi Gamma-ray Space Telescope (formerly known as ... -
Geometric modelling of radio and γ-ray light curves of 6 Fermi LAT pulsars
(Sissa Medialab, 2010)The Fermi Large Area Telescope (LAT) has recently reported the detection of pulsed γ-rays from 6 young pulsars (J0631+1036, J0659+1414, J0742−2822, J1420−6048, J1509−5850, and J1718−3825), all exhibiting single-peaked ... -
The extraction of the temperature gradient from measured temperature profiles with uncertainty propagation, as applied to the high temperature test unit
(SAAM, 2010)This paper highlights the usefulness of applying analytical methods for uncertainty analysis to a least-squares polynomial fit. It also presents an equation to calculate the confidence interval in the slope of a regression ... -
The validation of single point measurements for the localization of multiple harmonic sources
(IEEE, 2010)Power quality management requires inexpensive and simple methods for electric power quality monitoring. This paper investigates the validity of single point measurements for the localization of sources of waveform distortion ... -
A non-linear simulation model of an active magnetic bearings supported rotor system
(IEEE, 2010)Nowadays active magnetic bearings (AMBs) are utilized in a wide range of applications including high-speed flywheel energy storage devices. This paper aims at reporting on the modeling and simulation of a flywheel energy ... -
Multivariable H∞ control for an active magnetic bearing flywheel system
(IET, 2010)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 ... -
Challenges faced by divergent ICT schools regarding branding and establishing research foci. Panel discussion held at SACLA 2010, Cullinan, 4-6 June 2010.
(2010)The audience will be informed about the process of establishing a new research niche area in a School of Information Technology situated on the Vaal Triangle Campus (VTC) of the North-West University (NWU). The School ... -
Developing multivariate models to predict abnormal stock returns - using cross-sectional differences to identify stocks with above average return expectations
(SCITEPRESS (Science and Technology Publications, Lda.), 2010)This paper describes the development of multivariate models used to identify stocks with above average return expectations. While most other research involving the development of stock return models involves time-series ... -
Evaluating predictors of abnormal stock returns multivariate models
(ACTA Press, 2010)In recent years much research effort has been spent on the development of statistical and neural network techniques to predict abnormal stock returns. Much previous work focused on time series prediction of stock returns, ... -
A comparison of wireless node topologies for network coding using practical path-loss models
(IEEE, 2010)In this paper, we discuss the physical arrangement of wireless nodes to form topologies suitable for the implementation of Network Coding. Boundaries for the most favorable placement of the nodes to form Bow-Tie and Butterfly ... -
Error correction with the implicit encoding capability of random network coding
(Springer, 2010)In this paper, we present a technique for a network error correcting code using Random Network Coding. We introduce a novel error correction scheme that uses the implicit encoding capability of Random Network Coding. This ... -
A Preliminary Study for Post-Kyoto Period for Turkey by MARKAL Model
(2010)There are several mathematical models that have been developed for assessing specific energy systems and MARKAL, that has been developed by the Energy Technology Systems Analysis Program (ETSAP) of the International Energy ... -
On the assessment of voltage unbalance
(IEEE, 2010)The management of voltage unbalance in a power system is supported by the knowledge on the contribution of a single unbalanced load/source to the total level of voltage unbalance observed at a Point of Common Coupling (PCC) ...
