Author:Van Dyk, FE; Bekker, J; Mostert, MDate:Apr 2005This paper gives an overview of a discrete-event simulation study that was performed on pallet movement at Fresh Produce Terminals in the port of Durban, South Africa. The study formed part of an extended study of the logistics infrastructure ...Read more
Author:Dlamini, I; Olivier, M; Grobler, MDate:Jun 2009This paper extends work on a forensic model for traffic isolation based on Differentiated Services (DiffServ) and measures its performance by using a simulation. The simulated model has four basic components: traffic generators, the DiffServ ...Read more
Author:Steyn, WJVDM; Denneman, EDate:Oct 2008The objectives of this paper is to provide guidance on the practical management of temperature (pavement and loading tires) in Heavy Vehicle Simulator (HVS) tests, the potential effects of these temperatures on the outcomes of the test and ...Read more
Author:Van Wyk, Marius S; Mostert, Frederik J; Cloete, William E; Mattheyse, RichardDate:Jul 2019A simulation tool was used to investigate the comparative effects of air and water in a gap between two detonic transfer elements. A specific model configuration was used to position a donor and acceptor in air and water environments, ...Read more
Author:Jansen van Rensburg, Gerhardus J; Kok, S; Wilke, DNDate:Sep 2014Data is available for different hard metal samples tested in compression using a modified tensile test specimen. Three strain gauges were placed 120 degrees apart around the circumference of the centre of the test section. The spread of the ...Read more
Author:Jansen van Rensburg, Gerhardus J; Kok, S; Wilke, DNDate:Jul 2012This conference contribution focusses on the invertibility of non-ideal material tests to accurately determine material parameters. This is done by attempting to model non-ideal test cases and comparing strains as well as force history to the ...Read more
Author:Masindi, Vhahangwele; Mugera, GW; Tutu, HDate:Mar 2017The present study reports the optimum conditions for intercalating the Al(sup3+) species to bentonite clay matrices and evaluate the potential of using Al(sup3+)-modified bentonite clay (Alum-Bent) for removal of oxyanionic species of As, B, ...Read more
Author:Cawood, MP; Robinson, GA; Dobson, DADate:Jun 1976Those knitting variables which are considered critical in the knitting of fine staple yarns on a single jersey circular machine have been investigated in terms of knitting performance.Read more
Author:Hunter, L; Cawood, M; Dobson, DADate:Jul 1975One of the aims of this investigation was to determine in which particular course a yarn break occurred; different coloured yarns were used at the various feeders.Read more
Author:Debnath, S; Ballav, N; Maity, Arjun; Pillay, KDate:Jan 2015Polyaniline-coated lignin-based adsorbent (PLC) was synthesized and used for uptake of reactive dye eosin yellow (EY) from aqueous solution. The adsorption capability of the adsorbent was found to be more effective than the unmodified adsorbent ...Read more
