(University of Venda, 2015)Teaching and learning environments have become more complex and diverse, where effective leadership is to enhance the achievement of high standards of educational success. The evolving nature of school environments in ... -
Achieving energy efficiency with medium voltage variable speed drives for ventilation-on-demand in South African mines
(Elsevier, 2019)The sustainability of the mining industry is contingent on the industry's ability to improve upon the status quo of operational efficiency. The advancement of energy efficient technologies coupled with modern strategies ... -
Achieving the efficiency frontier in IT service delivery
(IBIMA, 2010)This paper researches and implements the best practices that lead to best performance in Information Technology service delivery. A customer quality defined standard is created by benchmarking the Information Technology ... -
Achieving the millenium and sustainable development goals in Africa: what role for female social workers
(IFE Centre for Psychological Studies (ICPS), 2017)The point that African continent has been trying to solve its development challenges will be an overstatement. One of the major efforts was the decision taken at the United Nations (UN) Millennium Summit in September 2000 ... -
Acid leaching of heavy metals from bentonite clay, used in the cleaning of acid mine drainage
(SAIMM, 2010)Heavy metals and sulphates in acid mine drainage (AMD) can be adsorbed onto bentonite clay, leaving clean water and a heavy metal loaded clay precipitate as products. Due to the toxicity of heavy metals, the clay could ... -
Acknowledging and protecting language rights on SABC TV through the use of subtitles
(Unisa Press/Taylor&Francis, 2011)In this article the use of subtitles is proposed as a way by means of which the problem of acknowledging and recognising language rights on SABC TV can be addressed. The concept of language rights is approached in terms ... -
Acquisition of ownership inside virtual worlds
(Pretoria University Law Press (PULP), 2013)Die artikel het ten doel om as kort inleiding te dien tot die manier waarop eiendom binne in ’n virtuele wêreld verkry kan word. Die Suid-Afrikaanse sakereg word as agtergrond gebruik om die nuwe veld van virtuele goederereg ... -
Actantial model of Judith, a key to unlocking its possible purpose: a greimassian contribution
(Old Testament Society of South Africa (OTSSA), 2015)The goal of this article is to investigate the possible purpose of the Greek apocryphal book of Judith. The investigation of the possible purpose of Judith has attracted the interest of many scholars and varying contributions ... -
Actinellopsis murphyi gen. et spec. nov.: a new small celled freshwater diatom (Bacillariophyta, Eunotiales) from Zambia
(Magnolia Press, 2014)In this paper we describe Actinellopsis murphyi gen. et spec. nov. a small heteropolar and dorsiventral diatom from a seep habitat in Zambia. This novel taxon has the chief distinguishing characteristic, along with its ... -
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 ... -
Action research for the 21st century: exploring new educational pathways
(Unisa, 2014)Twenty years into democracy in South Africa, poverty and disease continue to limit the life prospects of the majority of people. Researchers in higher education have an opportunity, not to mention a moral obligation, to ... -
Activation gap generators in neural networks
(In Proc. South African Forum for Artificial Intelligence Research (FAIR2019), 2019-12)No framework exists that can explain and predict the generalisation ability of DNNs in general circumstances. In fact, this question has not been addressed for some of the least complicated of neural network architectures: ... -
Activation in the context of the unemployment insurance system in South Africa
(Juta, 2011)The main aim of labour market activation policies is to bring jobless people from unemployment or inactivity into work or, at the very least, to influence the employment prospects of the unemployed positively. Activation ... -
An active hybrid energy storage system utilising a fuzzy logic rule-based control strategy
(MDPI, 2020)The research presented in this paper documents the implementation of an active hybrid energy storage system that combined a battery pack and an ultracapacitor bank. The implemented hybrid energy storage system was used ... -
Active magnetic bearing condition monitoring
(Emerald, 2013)In this paper, condition monitoring of the internal parts of a radial active magnetic bearing (AMB) system is performed by means of Cepstrum analysis, Wigner-Ville Distributions (WVD) and enveloped Equi-Sampled Discrete ... -
Active surface area approximation in a lead-acid cell for optimal performance in renewable energy systems
(IFAC, 2014)In a renewable energy system, lead-acid batteries are required to last as long as possible whilst providing deep discharges and are usually charged in an intermittent manner. This type of operation is severely detrimental ... -
Activities of 11-azaartemisinin and N-sulfonyl derivatives against asexual and transmissible malaria parasites
(Wiley, 2017)Dihydroartemisinin (DHA), either used in its own right or as the active drug generated in vivo from the other artemisinins in current clinical use—artemether and artesunate—induces quiescence in ring-stage parasites of ... -
