Author:Van den Bergh, F; Van Wyk, MA; Van Wyk, BJDate:2006This paper presents two new schemes for interpolating missing samples in satellite diurnal temperature cycles (DTCs). The first scheme, referred to here as the cosine model, is an improvement of the model proposed in [2] and combines a cosine ...Read more
Author:Verryn, SD; Snedden, CL; Eatwell, KADate:Jun 2009Tree breeders attempt to predict the genetic gains that are likely to be achieved through selection and breeding of new generations, using stochastic or deterministic modelling. There are many factors that may cause a discrepancy between the ...Read more
Author:Butgereit, L; Botha, RADate:Oct 2013Mobile Instant Messaging (MIM) systems have produced a new convention in writing where vowels are often omitted, where new suffixes have appeared, where numerals and symbols often appear in the place of letters which have a similar shape or ...Read more
Author:Bogaers, Alfred EJ; Jansen van Rensburg, GJDate:Sep 2018In this paper we investigate different numerical techniques to approximate and model gas dispersion, with a primary focus on modelling the buoyancy effects of dense gasses. We compare the popular Gaussian dispersion model with three different ...Read more
Author:Haelterman, R; Bogaers, Alfred EJ; Degroote, JDate:Feb 2018In many cases, different physical systems interact, which translates to coupled mathematical models. We only focus on methods to solve (strongly) coupled problems with a partitioned approach, i.e. where each of the physical problems is solved ...Read more
Author:Bezuidenhout, PH; Smith, S; Mbanjwa, M; Land, KJ; Joubert, T-HDate:Nov 2015This study compares the performance between two commercially-available electrically conductive silver inks, Harima NPS-J nanopaste and the NBSIJ-FD02 Mitsubishi conductive ink, used in rapid prototyping of electronic circuits. The comparative ...Read more
Author:Ntshangase, Cynthia SDate:Aug 2019This paper presents the study of the permanence of the ear shape. The focus is on comparing ear recognition methods using images affected by illumination and geometrical changes. The main aim of the study is to determine the permanence of the ...Read more
Author:Mlambo, CS; Nelwamondo, Fulufhelo V; Mathekga, Mmamolatelo EDate:Aug 2014In this paper, two effective and mostly used Hough Transform (HT) based fingerprint alignment approaches are compared, namely; Local Match Based Alignment (LMBA) and Discretized Rotation Based Alignment (DRBA). The comparison was performed ...Read more
Author:Thompson, MW; Vink, ER; Fairbanks, DHK; Ballance, A; Shackleton, CMDate:May 2001The recent completion of the South African National Land-Cover Database and the Vegetation Map of South Africa, Swaziland and Lesotho, allows for the first time a comparison to be made on a national scale between the current and potential ...Read more
Author:Kleynhans, W; Salmon, BP; Olivier, JC; Wessels, Konrad J; Van den Bergh, FDate:Jul 2011In this paper, a change detection accuracy comparison is made between a recently proposed EKF method and a sliding window. Fast Fourier Transform(FFT) alternative within a spatio-temporal change detection framework. Both methods produce a ...Read more
Author:Bachoo, A; Tapamo, J-RDate:Mar 2009Identification of individuals using iris recognition is an emerging technology. Segmentation of the iris texture from an acquired digital image of the eye is not always accurate - the image contains noise elements such as skin, reflection and ...Read more
Author:Robinson, GA; Turpie, DWFDate:Oct 1978The performance and physical properties of fibre, yarn and fabric produced from a 64's quality imported merino wool, a Cape merino 64's wool and a 50/50 blend of these has been investigated.Read more
Author:Kgarume, Thabang E; Brovko, Fatheela; Van Schoor, MichaelDate:Sep 2015This paper aims to demonstrate, through practical examples and numerical modelling, the trade-off between range and resolution in ground penetrating radar (GPR) prospecting. GPR surveys can easily fail when the target and host rock properties ...Read more
Author:Moller, H; Govender, G; Stumpf, WE; Pistorius, PCDate:2010The heat treatment response of semisolid metal high pressure die cast Al-7Si-Mg alloys A356 and F357 was studied and compared. It was found that the heat treatment behaviour of alloy F357 is influenced markedly by the stability of the Mg ...Read more
