Author:Blight, JJ; Gush, Mark B; Le Maitre, David C; Jewitt, GPWDate:Sep 2005Disruption of the hydrological regime caused by afforestation is well documented. Several sets of experimental catchments were set up in South Africa between 1935 and 1980 specifically to quantify such impacts. Data emanating from these ...Read more
Author:Oelofse, Suzanna HH; Mouton, CDate:Oct 2014The waste sector has been identified as a sector which can contribute towards South Africa’s economic growth and the creation of green jobs. Policies and regulations are often identified as a potential limiting factor for growth in the waste ...Read more
Author:Muswema, Aubrey P; Chetty, P; Okem, P; Oelofse, Suzanna HHDate:Oct 2018This case study is an overview investigating the interaction between severe weather incidents and solid waste management. The study seeks to understand how extreme weather events affect the implementation of the waste hierarchy (an approach ...Read more
Author:Muthige, Mavhungu S; Engelbrecht, Francois ADate:Oct 2016Regional climate models (RCMs) provide finer-scale simulations than those of Global climate models (GCMs), whilst being forced by the output of the host GCMs. In this study, we examine the influence of various strengths of spectral nudging ...Read more
Author:Viljoen, NMDate:Sep 2012Home-based care (HBC) is an effective service model to reduce the burden on a country's health and welfare systems. In South Africa, the orphaned and vulnerable children crisis has become the focus of HBC programmes. These programmes are ...Read more

Author:Mathumo, TW; Swart, TG; Focke, Richard WDate:Sep 2017The use of GNU Radio in order to explore FMCW radar is growing rapidly, where it is used for radar signal processing. In this paper we implement FMCW surveillance radar for drone detection on SDR using GNU Radio and the USRP B210. The requirement ...Read more
Author:Bogaers, Alfred EJ; Jansen van Rensburg, GJ; Marquart, R; Skatulla, SDate:Sep 2018In this paper, we outline the implementation of Hibler’s visco-plastic (VP) sea ice model into OpenFOAM, an opensource finite-volume modelling toolkit. Hibler’s visco-plastic model is arguably the most widely used description of sea ice ...Read more
Author:Chiranjan, Ashill; Duvenhage, Bernardt; Nicolls, FDate:Dec 2016Digital image processing (DIP) and computational photography are ever growing fields with new focuses on coded aperture imaging and its real world applications. Traditional coded aperture imaging systems consisted of statically coded masks ...Read more
Author:Sotenga, PZ; Djouani, K; Kurien, AM; Mwila, MartinDate:Jun 2020Internet of Things (IoT) is usually associated with the acquisition of sensor node information and controlling of things. However, the inadequateness of location information of these sensor nodes compromises the intelligence of the IoT network. ...Read more
Author:Mkuzangwe, Nenekazi NP; McDonald, Andre M; Nelwamondo, Fulufhelo VDate:Aug 2015This work implements two anomaly detection algorithms for detecting Transmission Control Protocol Synchronized (TCP SYN) flooding attack. The two algorithms are an adaptive threshold algorithm and a cumulative sum (CUSUM) based algorithm. ...Read more
Author:Van der Merwe, JN; Wojno, L; Toper, AZDate:Feb 2001Several new mining, rock engineering and environmental control technologies aimed at improving safety have been developed in the past decade or so.

Author:Venter, CJ; Grobler, H; AlMalki, KADate:Dec 2011The Cell-Averaging Constant False-Alarm Rate (CA-CFAR) algorithm was implemented and optimized in software on the NVIDIA Tesla C1060 GPU architecture for application in pulsed-Doppler radar signal processors. A systematic approach was followed ...Read more
Author:Dlungwana, Wilkin S; Roux, E; Setswalo, L; Lazarus, SDate:Nov 2008South Africa is a technology colony. A technology colony is merely a stage of technological development of a country and should neither be something to be ashamed of, nor necessarily seen as a disaster. Remaining one should not be a fate to ...Read more
Author:Duvenhage, B; Delport, JP; De Villiers, JDate:Jun 2010Image registration forms the basis of many computer vision tasks. The Lucas-Kanade image registration algorithm is known to efficiently solve the sub-problem of rigid image registration. It is therefore often used in image stabilisation ...Read more
