Author:Ngobeni, Sipho J; Venter, HS; Burke, Ivan DDate:Jan 2010Over the past decade, wireless mobile communication technology based on IEEE 802.11 Wireless Local Area Networks (WLANs) has been adopted worldwide on a large scale, resulting in the increase of the wireless users. However, as the number of ...Read more
Author:De Villiers, Johan P; Leuschner, FW; Geldenhuys, RDate:18 Jan 2010Most current lens distortion models use only a few terms of Brown's model, which assumes that the radial distortion is dependant only on the distance from the distortion centre, and an additive tangential distortion can be used to correct ...Read more
Author:Mbecke, PDate:Jun 2010This paper is based on an in-progress Ph.D. research themed: “Modeling the Differential Incidence of Child Abuse, Neglect and Exploitation in Poor Households in South Africa”. The aim of the research is to build a theoretical grounding and ...Read more
Author:Matsebe, O; Holtzhausen, S; Kumile, CM; Tlale, NSDate:Dec 2008The “solution” of the Simultaneous Localisation and Mapping (SLAM) problem has been one of the notable successes of the robotics community. SLAM has been formulated and solved as a theoretical problem in a number of different forms. SLAM has ...Read more
Author:Dube, CDate:Nov 2011Mobile manipulators are used in a number of different applications such as bomb disposal, mining robotics, and search and rescue operations. These mobile manipulators are highly susceptible to tip over due to the motion of the manipulator or ...Read more
Author:Kemp, N; Breetzke, GD; Cooper, Antony KDate:Sep 2020In this study, we model the risk of robbery in the City of Tshwane in South Africa. We use the collective knowledge of two prominent spatial theories of crime (social disorganization theory, and crime pattern theory) to guide the selection ...Read more
Author:Rezai, O; Kleinhans, A; Matallanas, E; Selby, B; Tripp, BPDate:Oct 2014The monkey anterior intraparietal area (AIP) encodes visual information about three-dimensional object shape that is used to shape the hand for grasping. We modeled shape tuning in visual AIP neurons and its relationship with curvature and ...Read more
Author:Patanaik, A; Anandjiwala, RDDate:Mar 2008This paper presents the results from a study on the water permeability behaviour of nonwovens produced from the hemp fibres. Three different types of needle-punched nonwovens are produced by varying the feed rate of fibres during the ...Read more
