Author:Rogers, DEC; Molefe, GS; Gwensa, Q; Van Den Bergh, C; Kristiansen, T; Otto, JBDate:Sep 2006This paper addresses the need for quantitative data for planning health care risk waste (HCRW) management from hospitals and clinics in South Africa. Quantitative estimates of HCRW generation and treatment capacity are determined for hospitals ...Read more
Author:Roux, FS; Zhang, YDate:Sep 2014Experimental setups for the optical implementation of projective measurements in the Laguerre-Gaussian basis are discussed. Special attention is given to the case where the measurements are made with the aid of single-mode fibers that are ...Read more
Author:Mouton, H; De Villiers, JPDate:2012A dramatic increase in rhino poaching, if allowed to continue at current rates, is threatening South Africa's rhino population with extinction. The available detection and prevention systems are not sufficient in solving this crisis. Targets ...Read more
Author:Mouton, H; De Villiers, JPDate:Aug 2012A dramatic increase in rhino poaching, if allowed to continue at current rates, is threatening South Africa's rhino population with extinction. The available detection and prevention systems are not sufficient in solving this crisis. Targets ...Read more
Author:Uys, H; Biercuk, M; Van Devender, AP; Bollinger, JJDate:Sep 2010The authors study pulse sequences that dynamically decouple 9Be+ ions from their decohering environment. The noise environment the ions see is artificially synthesized to emulate a variety of physical systems. By incorporating measurement ...Read more
Author:Land, K; Potgieter, S; Mbanjwa, MDate:Nov 2008The CSIR is developing a new technology, broadly referred to as microfluidics, which deals with the behaviour, precise control and manipulation of fluids - with applications in areas such as micro fuel cells, disease detection, chemical and ...Read more

Author:Funke, Nicola S; Nienaber, SDate:Jan 2012This paper aims to analyse how to encourage science uptake, here defined as the uptake and use of scientific research products (including journal articles, scientific reports, tools, expert knowledge, etc.), in the South African context. While ...Read more
Author:Davel, M; Martirosian, ODate:Sep 2009The deployment of speech technology systems in the developing world is often hampered by the lack of appropriate linguistic resources. A suitable pronunciation dictionary is one such resource that can be difficult to obtain for lesser-resourced ...Read more
Author:Davel, MHDate:Aug 2005Bootstrapping techniques have the potential to accelerate the development of language technology resources. This is of specific importance in the developing world where language technology resources are scarce and linguistic diversity is high. ...Read more
Author:Modipa, T; Davel, MHDate:Nov 2010This study focuses on the effective pronunciation modelling of words from different languages encountered during the development of a Sepedi automatic speech recognition (ASR) system. While the speech corpus used for training the ASR system ...Read more
Author:Naicker, K; Mneney, SHDate:Jun 2006The research aims to characterise the performance of the link by evaluating the effects of multipath propagation under various meteorological conditions. A LOS link was established between the Howard College and Westville campuses of UKZN and ...Read more
Author:Malatji, Tsholofelo M; Willers, Cornelius J; Willers, MSDate:Dec 2018Infrared guided missiles pose a threat to both military and civilian aircraft, and as such, the development of effective countermeasures against this threat remains vital. The effectiveness of various jamming code signals on the tracking ...Read more
Author:Malan, DF; Napier, JAL; Watson, BPDate:Dec 1994The influence of an interface on the initiation and propagation of fractures was investigated using the Brazilian tensile test (diametral compression of a disc). Failure in the Brazilian test takes the form of an extension fracture in the ...Read more
Author:Belyi, VN; Khilo, NA; Kazak, NS; Ryzhevich, AA; Forbes, ADate:May 2011The authors investigate the generation and transformation of Bessel beams through linear and nonlinear optical crystals. They outline the generation of high-order vortices due to propagation of Bessel beams along the optical axis of uniaxial ...Read more
Author:Litvin, IA; McLaren, MG; Forbes, ADate:Aug 2008The investigation into Bessel beams has been a topic of immense research during the past 20 years, due to the interesting properties they display. Bessel beams not only exhibit diffraction free propagation, but also reconstruction of the ...Read more
Author:Chaibi, A; Mafusire, C; Forbes, ADate:Sep 2013The orbital angular momentum of light has been suggested as a means of information transfer over free-space, yet the detected optical vortex is known to be sensitive to perturbation. Such effects have been studied theoretically, in particular ...Read more
