Author:De Wet, Febe; Marais, L; Klop, DDate:Sep 2015The purpose of this study was to measure the efficacy of an eBook to improve the vocabulary and word recognition skills in an Afrikaans speaking group of lower socio-economic status of 6- to 7-year old children with poor vocabulary. The main ...Read more
Author:Marais, LDate:Oct 2015Mobile technology and mobile development platforms provide a rich ecosystem within which language and speech related technologies can be developed. Specifically, text-to-speech (TTS) technology provides the opportunity for personalised and ...Read more
Author:Pieterse, AmyDate:Oct 2014It is well known that the city regions attract migrants from across the country because of their roles as economic engines and job baskets in South Africa. To address urbanisation implications it is imperative to better understand some of the ...Read more
Author:Mvelase, PS; Dlodlo, N; Mathaba, SU; Krause, C; Kabanda, SKDate:Oct 2009This paper reports on a study to determine the information requirements of communities in deep rural areas on government services and how this information can be made available to them. The study then proposes an e-government theoretical ...Read more
Author:Umuhoza, D; Agbinya, JI; Vahed, AnwarDate:2010Sensory data also known as Geospatial data is collected in-situ or remotely by different types of sensors from different geographic locations, by different agencies and over a period of time. A vast amount of data is processed via web services. ...Read more
Author:Shatalov, M; Fedetov, I; Tenkam, HMDDate:Mar 2008Modern theories of one-dimensional bar vibrations account for lateral effects, which are substantial in the case of relatively thick bars. For example, in the Rayleigh-Love and Rayleigh-Bishop models the lateral displacements are supposed to ...Read more
Author:Shatalov, M; Fedotov, I; Tenkam, HM; Fedotova, TDate:Sep 2010The conventional theory of the piezoelectric rod is based on an assumption that its lateral vibrations are negligible. In this case the rod, vibration could be described in terms of one-dimensional wave equation and a set of mechanical and ...Read more
Author:Greben, JMDate:28 Feb 2006In this paper the author discusses a quantitative theory of trend analysis. Often trends are based on qualitative considerations and subjective assumptions. In the current approach the author makes use of extensive data bases to optimise the ...Read more
Author:Chen, H; Botef, I; Guduri, B; Vallabhapurapu, SDate:Dec 2009The authors consider Polydimethylsiloxane (PDMS) as a prospective structural material candidate for a Micro Fuel Cell. The introduction of such a polymer as structural material will reduce the mass and the size of the micro fuel cell and ...Read more
Author:Masina, Bathusile N; Mwakikunga, Bonex W; Elayaperumal, M; Forbes, A; Bodkin, RDate:Jul 2011At present it is known that diamond tool degrades with time as it is normally used at high temperatures. One of the question the authors like to answer in this study is whether thermally induced problems in diamond tool arise as a result of ...Read more
Author:Bell, Teboho; Forbes, A; Ngcobo, Sandile; Naidoo, DarrylDate:Mar 2016We measured the thermally induced lens from the coefficient of defocus aberration using a Shack-Hartmann wavefront sensor (SHWFS). As a calibration technique, we infer the focal length of standard lenses probed by a collimated Gaussian beam ...Read more
Author:Bandyopadhyay, Jayita; Mekoa, Raphaale C; Skosana, Sifiso; Ray, Suprakas SDate:Nov 2020Nucleated polypropylene (PP) masterbatch and the nanoclay-containing composite of PP are prepared by reactive processing method to improve the thermo-mechanical properties of virgin PP. PP masterbatch and the nanocomposite exhibits pronounced ...Read more
Author:Kumirai, T; Bole, Sheldon; Conradie, Dirk CUDate:Oct 2012A thermal simulation model was prepared for a “typical” suburban building of 120 square meters and nine different passive designs were simulated to evaluate their impact on the heating and cooling load.Read more
Author:Masina, Bathusile N; Forbes, A; Ndwandwe, OM; Hearne, G; Mwakikunga, Bonex WDate:Mar 2009In this study the authors make use of laser heating of HTHP industrial diamond, as well as the optically measured temperature profile of the diamond surface, to study temperature induced changes to the diamond structure, both chemically and ...Read more
Author:Bell, Teboho; Naidoo, Darryl; Forbes, AndrewDate:Jul 2014The effects of a temperature gradient in a laser crystal in an end-pumped configuration in a solid-state laser resonator results in thermally induced aberrations. Of particular interest we measure the thermally induced lens from the coefficient ...Read more
Author:Steyn, WJvdM; De Beer, Morris; Visser, ATDate:Aug 1997The aim of this work was to quantify the structural behaviour of rehabilitated pavements and to optimise the life-cycle cost for the road agency.Read more
Author:May, Siyasanga I; Pratt, Lawrence E; Bokoro, PDate:Jan 2020Photovoltaic modules are normally tested under standard test conditions defined by the International Electrotechnical Commission, but these conditions are different from typical field condition. The standard test conditions for PV modules is ...Read more
Author:Marais, Mario ADate:Nov 2010The concept of sustainable development has increased in importance ever since the coming to prominence of environmental critiques of development in the 1980s. The very concept of sustainability has evolved as research on the dynamics of ...Read more
Author:Du Plessis, CDate:Sep 2006Sustainable development, and with it sustainable construction, is a continuously evolving concept. This has resulted in several iterations of “green” building – from early notions of durability, flexibility, natural building and returning to ...Read more
