Author:Du Plessis, L; Strauss, PJ; Perrie, BD; Rossmann, DDate:Oct 2007This paper discusses the prediction of crack width using the International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) model which predicts early age shrinkage. The model was modified to include ...Read more
Author:Schulze, C; Roux, FS; Dudley, Angela L; Rop, R; Duparre, M; Forbes, ADate:2015We introduce a class of light field that angularly accelerates during propagation. We show that the acceleration (deceleration) may be controlled by adjustment of a single parameter, and tuned continuously, down to no acceleration at all. As ...Read more

Author:Malan, AG; Oxtoby, Oliver FDate:Sep 2012In this paper we propose a fast, parallel 3D, fully-coupled partitioned hybridunstructured finite volume fluid–structure-interaction (FSI) scheme. Spatial discretisation is effected via a vertex-centered finite volume method, where a hybrid ...Read more
Author:Gledhill, Irvy MADate:Nov 2011This study concludes the possession of a theoretical framework for arbitrary manoeuvre which allows us to keep an eye on transformations. In the theory, relative frame equations are useful in guiding us in what to look for. The code is in the ...Read more
Author:Makondo, Ndivhuwo; Rosman, Benjamin S; Hasegawa, ODate:May 2018Online learning of a robot’s inverse dynamics model for trajectory tracking necessitates an interaction between the robot and its environment to collect training data. This is challenging for physical robots in the real world, especially for ...Read more
Author:Van Wyk, Llewellyn VDate:Aug 2015This chapter flows out of study (CSIR 2013b) prepared for the Presidential Infrastructure Coordinating Commission (PICC) in May 2013 which prepared a value proposition for the use of Innovative Building Technology (IBT) for the construction ...Read more
Author:Gledhill, Irvy MA; Nordström, JDate:01 Sep 2010Practical requirements are now arising in which significant acceleration takes place during flight; 5th generation missiles, such as A-Darter, execute turns at 100 g, where g is the acceleration due to gravity, and thrust from propulsion ...Read more
Author:Stoltz, M; Stoltz, George G; Obara, K; Wang, T; Bryant, DDate:Nov 2021Hidden Markov models (HMMs) are general purpose models for time-series data widely used across the sciences because of their flexibility and elegance. Fitting HMMs can often be computationally demanding and time consuming, particularly when ...Read more
Author:Gledhill, Irvy MA; Roohani, H; Biobaku, A; Skews, BDate:Jun 2016Theoretical work on transforming the Navier-Stokes equations into arbitrarily accelerating frames has included the continuity, momentum, and energy conservation equations. An analysis of the momentum equation in non-dimensional terms leads ...Read more
Author:Basson, FA; Jammine, E; Heyl, LDate:1984A research and demonstration project on the use and performance of low cost integral solar water heaters in urban low-income dwellings was carried out in 1982/83. The project involved technical and socio-economic components. This report ...Read more

Author:Adam, R; Kotzé, Paula; Van der Merwe, ADate:Jun 2011ERP systems are widely used by large enterprises for managing functional areas of the enterprise. However, recently ERP systems have also been introduced to the small enterprise market. ERP systems are now considered an important small ...Read more
Author:Henrico, S; Coetzee, S; Cooper, Antony K; Rautenbach, VDate:Oct 2020Geospatial information and technologies are widely used in South Africa, initially mostly with proprietary software but today, mature, open source alternatives such as QGIS are available. We wanted to find out if and why South African users ...Read more

Author:Herselman, Martha E; Botha, Adèle; Makitla, IDate:Feb 2012The components of Information and Communication Technology (ICT) are Computing, Connectivity, Content and Capacity. These components, dubbed the 4C Framework (because the name of each of these four components starts with letter “c”), are ...Read more
Author:Makitla, I; Fogwill, T; Botha, AdèleDate:Oct 2012The core approach of this research project, which is informed by the concept of “digital difference”, is to leverage the existing
technological infrastructure and capacity (know-how) in a community to enable delivery of ICT4D content and ...Read more
Author:Coetzee, L; Viviers, MI; Cunningham, P; Cunningham, MDate:May 2008Improving the accessibility of Internet web sites and portals is becoming more important as initiatives (such as the South African National Accessibility Portal), which address the marginalisation of persons with disabilities, gather momentum. ...Read more
Author:Coetzee, L; Olivrin, G; Vivier, IDate:Apr 2009Persons with disabilities are often marginalised from economy and society due to the lack of access to disability related information and services.
