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, ... -
THE RELATIONSHIP BETWEEN CONTEXTUAL FACTOR AND SERVICE DELIVERY PERCEPTIONS IN A MAJOR CITY IN SOUTH AFRICA
(IBC, 2021)South African municipalities have in recent times been piqued with unprecedented service delivery protests, indicative of a failure to provide these amenities as expected. With soaring levels of unemployment and ... -
Removal of COD from biodiesel wastewater using a hydrophobic polymer
(EARET, 2018)Biodiesel production is increasing internationally as an alternative fuel. This is due to the rapid depletion of non-renewable energy sources. Pure biodiesel product can be obtained by washing the product with hot water. ... -
Retinal vessel caliber and vessel reaction to light flicker in true normotensive young healthy black and white adults: the African-PREDICT study
(Karger, 2019)A detrimental shift in cardiovascular disease risk factors and a higher mortality level are reported in some black populations. The retinal microvasculature provides insight into the pathogenesis of systemic vascular ... -
Retrofit design of a line-start PMSM using the Taguchi method
(IEEE, 2016)This paper presents the implementation of the Taguchi method for a retrofit design of a line-start permanent magnet motor. To evaluate the viability of the method, the optimum designs obtained from both the Taguchi and a ... -
A review on switched reluctance machines for electric vehicle
(IEEE, 2016)Nowadays, switched reluctance machines (SRM) are gaining interest in the scientific community due to the advantages they offer. The SRM offers an overall efficiency similar to an induction motor of the same rating, since ... -
A risk based view on building a sustainable nuclear electricity industry in South Africa
(Wiley, 2014)This paper introduces a Nuclear Sustainability Risk Model, which reflects a proposed strategy for ensuring the sustainability of a nuclear electricity industry for South African in the long term. The model is used to ... -
Robopol: optical polarisation monitoring of blazars
(HEASA, 2016)The RoboPol program has been monitoring the R-band linear polarisation parameters of an unbiased sample of 60 gamma-ray-loud blazars and a “control” sample of 15 gamma-ray-quite ones. The prime drive for the program has ... -
Robust torque ripple mitigation of a line-start PMSM by means of the Taguchi method
(IEEE, 2019)—In this paper, a robust design framework is proposed to mitigate torque ripple for line-start permanent magnet synchronous machines (LS-PMSM) by using the Taguchi method. The framework is intended for fine-tuning initial ... -
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 ... -
Safety pharmacology of herbal medicines in South Africa
(Elsevier, 2019)The use of herbal medicine for treating various ailments has a deep history in South African traditional medicine. South Africa has a rich floral biodiversity which has been exploited for centuries mainly for day-to-day ... -
Search for High-redshift Blazars with Fermi/LAT
(Sissa Medialab, 2019)High-redshift blazars (z ≥ 2.5) are one of the most powerful classes of γ-ray sources in the Universe. These objects possess the highest jet powers and luminosities and have black-hole masses often in excess of 109 solar ... -
A search for optical counterparts of the complex Vela X system
(South African Institute of Physics, 2015)The pulsar wind nebula (PWN) associated with the Vela pulsar is a bright source in the radio, X-ray and gamma-ray bands, but not in the optical. This source is very near, lying at a distance of 290 pc, as inferred from ... -
Search for pulsed VHE gamma-ray emission from young pulsars with H.E.S.S.
(ICRC, 2008)We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescope system. Data on eleven pulsars, selected ... -
Securing number plates based on digital signatures and RFID
(IEEE, 2013)The automated detection of vehicles forms an important part of Intelligent Transportation Systems. The vehicle number plate is the primary token used for the identification of the vehicle; the number plates industry is ... -
Selective adsorption of heavy and light metals by natural zeolites
(PSRC, 2014)Recent studies have shown that zeolite can be applied through an ion-exchange process to remove metals from solutions. In this paper the potential of two zeolites to perform as sorbents for treatment of multi-metal system ... -
The selective targeting of cancer cells by using Pheroid® as a drug delivery system
(Elsevier, 2019)Pheroid® is a drug delivery system with possible use in the treatment of chronic diseases such as cancer and that enhances the efficacy of the treatment of chronic diseases [1]. Current cancer treatment is non-selective, ... -
Self-reported physical activity is not a valid method for measuring physical activity in 15 year old South African boys and girls
(Human Kinetics, 2018)Valid instruments for the assessment of physical activity remains a challenge in field studies. This study determine the level of agreement between objectively measured physical activity by ActiHeart® and the ...
