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

Author:Zunckel, M; Koosailee, A; Yarwood, G; Maure, G; Venjonoka, K; Van Tienhoven, AM; Otter, LDate:Jul 2006Monitoring of surface ozone over southern Africa has shown that ambient concentrations often exceed a threshold of 40 ppb at which damage to vegetation by ozone could be expected. The Cross Border Air Pollution Assessment Project (CAPIA) was ...Read more
Author:Smit, Jacoba E; Hanekom, T; Hanekom, JJDate:Sep 2009The objective of this study was to determine if a recently developed human Ranvier node model, which is based on a modified version of the Hodgkin-Huxley model, could predict the excitability behaviour in human peripheral sensory nerve fibres ...Read more
Author:Zunckel, M; Robertson, L; Tyson, PD; Rodhe, HDate:2000Ambient SO2 concentrations and atmospheric deposition of sulphur resulting from emissions on the industrialised highveld region of South Africa are estimated using the multi-scale atmospheric transport and chemistry (MATCH) modelling system, ...Read more
Author:Vogt, DRDate:Sep 2000In this thesis, Radio Tomography is the name of a geophysical technique for imaging the attenuation of high frequency continuous wave radio waves in the plane between two boreholes in the earth. One of the central problems of radio tomography ...Read more
Author:Shatalov, MY; Wallis, JR; Nicolaides, KEDate:Jun 2005A design and implementation of a 1-3 piezocomposite side scan transmit sonar array is considered. The theoretical approach to the array design is based on a new concept of one-dimensional modelling of 1-3 piezocomposite transducers, developed ...Read more
