The purpose of the project is to gain ...Read more
Author:Nxumalo, M; Nordengen, Paul ADate:Oct 2010There is compelling evidence that a significant factor contributing to the poor condition of much of Africa's rural road network is inadequate human resource capacity. This shortage of professional skills in road engineering inhibits proper ...Read more
Author:Smith, C; Meintjes, J; Aguado, RDate:Jan 2013As the Software Defined Radio (SDR) terminals evolve the complexity of these terminals and the waveforms they host get more and more complicated. The network capabilities and the new features introduced in such terminals (as SNMP) shorten the ...Read more
Author:Kleynhans, W; Olivier JC; Wessels, Konrad J; Van Den Bergh F; Salmon BP; Steenkamp Karen CDate:15 Dec 2009It is proposed that the NDVI time-series derived from MODIS satellite data can be modelled as a triply (mean, phase and amplitude) modulated cosine function. Secondly, a non-linear Extended Kalman Filter is developed to estimate the parameters ...Read more
Author:Naidoo, Kersch; Moolman, FSDate:Nov 2008This poster covers the development of a technology towards a novel bioartificial liver support system (BALSS) that is capable of providing liver functions, in patients with acute liver failure, while housed outside the body (extra corporeal). ...Read more
Author:Kleynhans, W; Olivier, JC; Salmon, BP; Wessels, Konrad J; Van den Bergh, FDate:Jul 2009It is proposed that the NDVI time series derived from MODIS multitemporal remote sensing data can be modelled as a triply (mean, phase and amplitude) modulated cosine function. A non-linear Extended Kalman Filter was developed to estimate the ...Read more
Author:Pritchard, SW; Malekian, R; Hancke, GP; Abu-Mahfouz, Adnan MIDate:Oct 2017Software-Defined Wireless Sensor Networking (SDWSN) is an emerging paradigm that seeks to alleviate the inherent resource constraint issues present in Wireless Sensor Networks (WSN) by adopting a Software-Defined Networking (SDN) approach to ...Read more
Author:Crafford, Gerhardus J; Rosman, BDate:Nov 2022Different reinforcement learning (RL) methods exist to address the problem of combining multiple different learners to generate a superior learner. These existing methods usually assume that each learner uses the same algorithm and/or state ...Read more
Author:Mdakane, L; van den Bergh, F; Moodley, DDate:Oct 2014The rapid increase in population and migration to urban areas has caused a pronounced increase in human settlements around the world. The diversity of land features, mixed-use settlements, terrain, and heterogeneity of building materials and ...Read more
Author:Marivate, V; Sefara, Tshephisho JDate:Aug 2020We study the effect of different approaches to text augmentation. To do this we use three datasets that include social media and formal text in the form of news articles. Our goal is to provide insights for practitioners and researchers on ...Read more
Author:Stoltz, George G; Nel, ALDate:Oct 2020In this paper, we improve image reconstruction in a single-pixel scanning system by selecting an detector optimal field of view. Image reconstruction is based on compressed sensing and image quality is compared to interpolated staring arrays. ...Read more
Author:Nkosi, MT; Mekuria, FissehaDate:May 2011Mobile devices are being considered as service platforms for mobile health information delivery, access and communication. However they face challenges with regard to delivering secure multimedia based health services due to limitations in ...Read more
Author:Hunter, Lawrance; Fan, JDate:Nov 2014Comfort is a highly subjective phenomenon, with no unanimously agreed quantitative definition. In the Oxford English Dictionary and Webster’s Third New International Dictionary, comfort is defined as ‘freedom from pain, trouble and anxiety; ...Read more
Author:Aramide, B; Pityana, Sisa L; Sadiku, R; Jamiru, T; Popoola, PDate:Jun 2021Farming tools are often exposed to high wear rate in dry agricultural land areas. This makes the farming activity to have problems of recurrent labour, idle time, and the extra expenses in replacing the damaged implements like ploughshares. ...Read more
Author:Naidoo, Darryl; Litvin, Ihar; Forbes, ADate:Feb 2017We investigate the selection of a flat-top beam and a Gaussian beam inside a laser cavity on opposing mirrors. The concept is tested external to the laser cavity in a single pass and double pass regime where the latter mimics a single round ...Read more
Author:Biermann, SM; Van Ryneveld, MDate:Jul 2007This finding suggests the need for a range of different housing typologies, with 'higher cost / higher potential benefit' housing typologies on scarce well-located land allocated to those with the best chance of exploiting those potential ...Read more
