It maps vulnerability to COVID-19 for the whole of South Africa, down to the level of the ...Read more
Author:Tulsi, KDate:Oct 2015This presentation looks at ways to create safer coastal and port infrastructure. It investigates methods such as numerical and physical modelling as ways to achieve this.Read more
Author:Price, M; Green, J; Dickens, JDate:Nov 2011A method for generating 3D maps of mines with thermal imaging texture from a robotic platform is presented. The objective is to use these models to generate risk maps that can be used to assess mine safety. Analysis will take place offline, ...Read more
Author:Sekoai, Patrick T; Chunilall, Viren; Ezeokoli, ODate:Jun 2023As a response to the environmental and societal issues that emanate from the high reliance on fossil fuels, the world is now transitioning toward a circular bioeconomy. Acidogenic biohydrogen production is envisaged as a clean fuel of the ...Read more
Author:Forbes, A; Dudley, Angela L; McLaren, MDate:Jun 2016Modal decomposition of light has been known for a long time, applied mostly to pattern recognition. With the commercialization of liquid-crystal devices, digital holography as an enabling tool has become accessible to all, and with it all-digital ...Read more
Author:Barros, E; Nelson, SWDate:Jun 2010The aim of this study was to use conventional breeding to increase the production in maize of the human monoclonal antibody 2G12, known to have potential therapeutic properties in the prevention of HIV-1 transmission. The recombinant antibody, ...Read more
Author:Conradie, Dirk CU; Kumirai, TDate:Jun 2012To design energy-efficient buildings using an optimal combination of passive design strategies it is necessary to understand the particular climate one is designing for. Predictive computational building performance requires a detailed set ...Read more
Author:Conradie, Dirk CU; Van Reenen, Tobias H; Bole, SheldonDate:Dec 2015The current six climatic regions map used in the SANS 204 (2011) South African National Building Standards does not optimally support quantified design decisions within the built environment. It also does not give an indication of the amount ...Read more

Author:Oosthuizen, Rudolph; Roodt, JHSDate:Oct 2008In the acquisition environment, smart systems and equipment represent the tip of the proverbial iceberg – it takes much more to realise a credible defence capability, that is, one that comprises all components of a user system to enable a ...Read more
Author:Nabarro, FRNDate:Feb 2002The creep rate in a land-based power station must be less than 10(-11) s(-1). At these low rates of deformation the transport of matter occurs by the migration of vacancies rather than by the glide of dislocations. A quantitative understanding ...Read more
Author:Carter, PDate:Jun 1998NDT, design calculations and metallurgical analysis were performed on specimens from a collapsed spray drier. Failure modes initially regarded as possible were: corrosion leading to reduced sections and loss of strength, fatigue and fracture, ...Read more
Author:Mturi, George AJ; Nkgapele, M; O'Connell, Johannes SDate:May 2012The increase in traffic loads and loading time in road pavements worldwide has resulted in the widespread usage of polymer modified binders (PMBs) since they offer increased resistance to pavement distresses. The extensive use of inherently ...Read more
