Author:Mngenge, NA; Nelufule, Nthatheni; Nelwamondo, Fulufhelo V; Msimang, MDate:Nov 2012Automatic Fingerprint Recognition Systems (AFRSs) rely on minutiae position and orientation within the fingerprint image for matching. Minutiae information is highly accurate provided that the fingerprint image matched is of high quality. ...Read more
Author:Molale, P; Twala, B; Seeletse, SDate:Nov 2011In this study, the application of classifiers to problems in fingerprint prediction is investigated. Six supervised learning and two statistical fingerprint classification methods (classifiers) are considered: linear discriminant analysis ...Read more
Author:Msiza, IS; Leke-Betechuoh, B; Malumedzha, TDate:Feb 2011Fingerprint re-alignment is an important aspect in the subject of fingerprint biometrics because a fingerprint that has been rotated, voluntarily or involuntarily, can have negative impact on the functionality of an automated fingerprint ...Read more
Author:Msiza, IS; Mathekga, Mmamolatelo E; Nelwamondo, Fulufhelo V; Marwala, TDate:Sep 2011Fingerprint image segmentation plays an important role in any fingerprint image analysis implementation and it should, ideally, be executed during the initial stages of a fingerprint manipulation process. After careful consideration of various ...Read more
Author:Marwala, T; Sibisi, SDate:Jan 2005Finite element (FE) models are widely used to predict the dynamic characteristics of aerospace structures. These models often give results that differ from measured results and therefore need to be updated to match measured results. Some of ...Read more
Author:Botha, N; Kok, S; Inglis, HMDate:Dec 2012Corneal biomechanical properties are an important element in the study of corneal biomechanics. There are currently two techniques to obtain these properties; an inflation test and the strip extensiometry test. As the inflation test has been ...Read more
Author:Mc Dougall, IDate:2007Finite element models were generated of two submerged arc furnaces of different geometries. A 48MW circular furnace and a 68MW 6-in-line rectangular furnace were studied. The electrodes, raw material, slag and molten metal were included in ...Read more
Author:Kok, S; van Rensburg, JGJDate:01 Sep 2010In anthropology, the finite element method (FEM) is frequently applied to determine the validity of hypotheses concerning the adaptation of biological form to suit functionality. Different geometries are analysed, and based on the predicted ...Read more
Author:Ritchie, Michaela C; Lück-Vogel, Melanie; Debba, Pravesh; Goodall, VDate:May 2017Medium spatial resolution sensors (10-30 m pixel size) have been used for land cover classification and monitoring for decades. However, these sensors do not have the required resolution to detect coastal specific land cover classes and ...Read more
Author:Walwyn, DDate:2007The sudden and dramatic growth of the mobile phone manufacturing sector in Finland is an interesting case study for science and technology (S&T) policy analysts. Mostly on account of the rapidity of this growth against a relatively static ...Read more
Author:Mcferren, GA; Roos, S; Terhorst, ALDate:2006AFIS (Advanced Fire Information System) is a joint initiative between CSIR and Eskom, the South African electricity utility. AFIS infers fire occurrences from processed remotely sensed data and triggers alarms to Eskom operators based on ...Read more
Author:Butgereit, L; Moonsamy, S; Thomson, T; Van Zyl, T; McFerren, GDate:Nov 2014Humanity has had a long historical relationship with fire. According to anthropologists, the first humanoid species learned to use and control fire approximately two million years ago. Using fire and controlling fire, however, are dramatically ...Read more
Author:Van Wilgen, BW; Biggs, H; O'Regan, SP; Mare, NDate:Apr 2000This paper analyses the fire history of the Kruger National Park (1.9 million ha), South Africa, for different periods in the park's history, where fire protection was followed by prescribed burning and then a 'natural' (lightning) fire policy. ...Read more
Author:Schrige, GU; Penderis, AHDate:Oct 1978References to 258 publications are presented together with summaries, keyword listings and a keyword index. This bibliography forms part of the South African contribution to the SCOPE project "The ecological effects of fire", 1977-1980.Read more
Author:van Wilgen, BW; Forsyth, GG; de Klerk, H; Das, Sonali; Khuluse, S; Schmitz, PDate:2010The authors used a spatial data base of fires within 10 protected areas covering >720 000 ha to examine the frequency, seasonality, size and cause of fires over four decades. Their study covered five fire climate zones and a range of mountain ...Read more
Author:Frost, PDate:2011Fires kill and injure hundreds of people in South Africa each year, and is also responsible for damage to property and diseases such as athma due to smoke inhalation. The Advanced Fire Information System (AFIS) was started in 2003 as a service ...Read more
