Author:Ludick, Chantel J; Van Heerden, QuintinDate:Jul 2022In many countries, including South Africa, data on employment is rarely available on a downscaled level, such as building level, and is only available on less detailed levels, such as municipal level. The aim of this research was to develop ...Read more
Author:Nkosi, Mpho C; Lysko, Albert A; Dlamini, Sabelo VDate:Dec 2018Networks have become an important feature of our day-to-day to life and therefore, user experience is an imperative goal to be achieved by network operators. Load balancing is a method of improving network performance, availability, minimizing ...Read more

Author:Fatoki, OS; Opeolu, BO; Genthe, Bettina; Olatunji, OSDate:Dec 2018A multi-residue method for the determination of the occurrence and prevalence levels of selected veterinary pharmaceutical residues in surface water was developed on a high performance liquid chromatography coupled to ultraviolet-visible ...Read more
Author:Kleebauer, M; Marz, Christopher A; Reudenbach, C; Braun, MDate:Dec 2023In the realm of solar photovoltaic system image segmentation, existing deep learning networks focus almost exclusively on single image sources both in terms of sensors used and image resolution. This often prevents the wide deployment of such ...Read more
Author:Botai, OJ; Sivakumar, V; Combrinck, CL; Rautenbach, CJDDate:2009In this study, data from the Southern Hemisphere ADditional OZonesondes (SHADOZ) are used to compute the spatially averaged water vapour (WVg) over low and mid-tropical Africa. Based on the SHADOZ stations, reanalysis data from the National ...Read more
Author:Musehane, Ndivhuwo M; Oxtoby, Oliver F; Reddy, DBDate:Oct 2016In this work, droplet-droplet interaction is modelled using a multiphase flow computational fluid dynamics approach coupled with a reduced order surface thin-film model. An existing multiphase flow model based on a multiple marker volume of ...Read more
Author:Musehane, Ndivhuwo M; Oxtoby, Oliver F; Reddy, BDDate:Nov 2018In this work, droplet–droplet interaction is modelled using a multi-scale approach which couples multiphase flow simulation using a volume of fluid method to a surface thin film model operating on the sub-grid scale. The volume of fluid model ...Read more
Author:Holloway, MDate:Oct 2012In this presentation the author presents the engineering design process from customer requirement to technology demonstrator hardware and the impact of the CSIR's work in the defence and safety area.Read more
Author:Stolper, RDate:Feb 2006This poster highlights the design and development of a camera which combines ultraviolet, infrared and visual imaging techniques for advanced diagnostic inspections, and also shows some evaluations carried out to demonstrate the operability ...Read more
Author:Swanepoel, Derick; Van den Bergh, FransDate:Mar 2017Earth observation data are typically compressed using general-purpose single-threaded compression algorithms that operate at a fraction of the bandwidth of modern storage and processing systems. We present evidence that recently developed ...Read more
Author:Frieslaar, Ibraheem; Irwin, BDate:Oct 2016This research investigates the use of a multi-threaded framework as a software countermeasure mechanism to prevent attacks on the verifypin process in a pin-acceptance program. The implementation comprises of using various mathematical ...Read more
Author:Salmon, BP; Kleynhans, W; Olivier, JC; Schwegmann, CP; Olding, WCDate:Jul 2015In this paper the authors present a 2-tier higher order Conditional Random Field which is used for land cover classification. The Conditional Random Field is based on probabilistic messages being passed along a graph to compute efficiently ...Read more
