Author:Brown, Dane; Bradshaw, KDate:Sep 2016The feature-level, unlike the match score-level, lacks multi-modal fusion guidelines. This work demonstrates a practical approach for improved image-based biometric feature-fusion. The approach extracts and combines the face, fingerprint and ...Read more
Author:Mdakane, L; Van den Bergh, FDate:Nov 2012Despite the fact that image texture features extracted from high-resolution remotely sensed images over urban areas have demonstrated their ability to distinguish different classes, they are still far from being ideal. Multiresolution grayscale ...Read more
Author:Nahman, AntonDate:2010Extended producer responsibility (EPR) is a policy concept aimed at extending producers’ responsibility for their products to the post-consumer stage of their products’ life cycle. One of the outcomes of an effective EPR programme is to move ...Read more
Author:Ortlepp, WD; Swart, AHDate:Nov 2002The submitted proposal for the GAP 818 project was formally approved during the first week of May 2001. The objectives of the proposed programme were, broadly, to examine possible ways of preventing the collapse of fractured rock from the ...Read more
Author:Loots, L; De Wet, Febe; Niesler, TDate:Nov 2010In this study we explore the extension of a small Afrikaans pronunciation dictionary by applying phoneme-tophoneme (P2P) and grapheme-and-phoneme-to-phoneme (GP2P)
conversion to an existing and more extensive Dutch pronunciation dictionary. ...Read more
Author:Duvenhage, B; Bouatouch, K; Kourie, DGDate:May 2011Backward polygon beam tracing methods, that is beam tracing from the light source (L), are well suited to gather path coherency from specular (S) scattering surfaces. These methods are useful for modelling and efficiently simulating caustics ...Read more
Author:Bidwell, NJ; Winschiers-Theophilus, HDate:Jun 2012Dilemmas arise in designing digital systems that enable rural dwellers to create, store and share digital content about their connections with their land because the design and use if technologies manifests the priorities and assumptions of ...Read more
Author:Rens, G; Ferrein, A; van der Poel, EDate:Nov 2008For sophisticated robots, it may be best to accept and reason with noisy sensor data, instead of assuming complete observation and then dealing with the effects of making the assumption. We shall model uncertainties with a formalism called ...Read more
Author:Bogaers, Alfred EJ; Kok, S; Reddy, BD; Franz, TDate:Jan 2015In this paper we introduce the idea of combining artificial compressibility (AC) with quasi-Newton (QN) methods to solve strongly coupled, fully/quasi-enclosed fluid-structure interaction (FSI) problems. Partitioned, incompressible, FSI based ...Read more
Author:Muwonge, BK; Chan, HADate:Apr 2008This paper highlights issues relating to signalling of IMS traffic, and how a truly seamless converged network may be achieved using cognitive radio technology. In this paper we propose implementation of the Resource Admission Control Subsystem ...Read more
Author:Marais, Laurette; Pretorius, LDate:Jan 2023The African languages Wordnet (AfWN) for Zulu (ZWN) was built using the expand approach, which relies on the translation of concepts in the Princeton WordNet (PWN), while retaining their PWN lexical categories. In this paper the focus is on ...Read more
Author:Taljaard, Susan; Van Niekerk, Lara; Joubert, WRDate:Nov 2009Estuaries are dynamic transition zones acting as filters and transformers of nutrients passing from catchments to the sea. The authors propose an extension to an existing southern hemisphere model on nutrient dynamics in estuaries to include ...Read more
Author:Knoesen, D; Arendse, C; Halindintwali, S; Muller, TDate:Jan 2008One of the prime components of a hot-wire (Cat) Chemical Vapor Deposition system is the filament used to pyro-catalytically crack the gases like silane. Burnt out tantalum filaments were studied to determine the possible improvement of lifetime ...Read more
Author:De Lange, Willem J; Nahman, Anton; Theron, ADate:May 2009The valuation of estuarine goods and services serves to highlight the degree to which estuaries contribute to human well-being and to show that the social cost of activities which contribute to estuary degradation could be greater than the ...Read more
Author:Peart, RDate:Jan 2001This article reviews the external factors that influence environmental performance of companies in South Africa, drawing on international and local literature. After considering factors within the natural, social, economic and institutional ...Read more
Author:Bell, Teboho; King, Gary; Litvin, IDate:Feb 2020This work proposes a method that can be used to control the transverse profile of the optical intensity distribution of a diode-end-pumped solid-state laser operating with a Gaussian seed beam. The transverse gain profie in an external amplifier ...Read more
Author:Berger, E; Crampton, Michael C; Nxumalo, NP; Louw, MEDate:Aug 2011Through modification of the flagellin type III secretion pathway of Bacillus halodurans heterologous peptides could be secreted into the medium as flagellin fusion monomers. The stability of the secreted monomers was significantly enhanced ...Read more
Author:Davel, M; Barnard, EDate:Apr 2006Various automated techniques can be used to generalise from phonemic lexicons through the extraction of grapheme-to-phoneme rule sets. These techniques are particularly useful when developing pronunciation models for previously unmodelled ...Read more
