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. Since several of these developments have either not been implemented properly or only implemented ...Read more
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
Author:Ilgner, Hartmut; Pienaar, SDate:Nov 2016Non-invasive monitoring of slurry pipelines with a new embedded system is described to complement existing remote sensing techniques via satellites. The behavior of the slurry inside the pipeline may cause sedimentation which may lead to ...Read more
Author:Arnold, Kathryn A; Le Roux, Alize; Makhanya, Sibusisiwe ADate:Sep 2018Climate-related natural disasters have been steadily increasing in both incidence and intensity across the globe over the last century. This is especially true for Ethiopia given the country’s high and recurrent exposure to extreme droughts ...Read more
