Author:Vhengani, L; Lubbe, M; Griffith, D; Lysko, MDate:Oct 2010The success or failure of any earth observation mission depends on the quality of its data. Data quality is assessed by determining the radiometric, spatial, spectral and geometric fidelity of the satellite sensor. The process is termed calval. ...Read more
Author:Engelbrecht, Jeanine; Inggs, MRDate:Aug 2016Surface deformations associated with shallow underground mining activities have significant implications for both the natural- and built environment. Environmental problems include the exacerbation of acid mine drainage and the alteration of ...Read more
Author:Olwal, TO; Van Wyk, BJ; Hamam, Y; Ntlatlapa, Ntsibane SDate:2009This paper addresses the problem of a scalable dynamic power control (SDPC) for wireless mesh networks (WMNs) based on IEEE 802.11 standards. An SDPC model that accounts for architectural complexities witnessed in multiple radios and hops ...Read more
Author:Naidoo, Darryl; Roux, FS; Dubery, Angela L; Litvin, Ihar; Piccirillo, BDate:Oct 2016We introduce a laser for generating all states on the Higher-order Poincaré sphere by coupling spin angular momentum to orbital angular momentum and we demonstrate that the OAM degeneracy of a laser may be broken.Read more
Author:Grundling, WDate:Oct 2012The purpose of this particular test is to
evaluate and identify the behaviour of
pressure in a semi-confined space, after
which it has been partially confined by
making use of a ballistic pendulum. The approach will be to conduct tests ...Read more
Author:Butgereit, LL; Botha, RADate:Sep 2010Scalability is a critical characteristic for successful software solutions - especially networked software and social software. Scalability can be defined as how well the software platform which provided help to primary and secondary school ...Read more

Author:Roro, Kittessa T; Mwakikunga, Bonex W; Tile, N; Forbes, ADate:Dec 2011Owing to their unique electronic and optical properties, nanocomposite thin films are widely used for converting solar radiation therapy into other conventional energy forms, such as heat and electricity. Carbon nanotube-based composites which ...Read more
Author:Loveday, Philip W; Long, Craig SDate:Apr 2012Guided wave based inspection and monitoring systems for railway tracks operate at frequencies where as many as 40 modes of propagation may exist. During the development of such systems it is advantageous to be able to measure the amplitude ...Read more
Author:Shatalov, MY; Fedotov, I; Joubert, SDate:May 2006It is known that vibrating patterns of an isotropic cylinder, subjected to inertial rotation over the symmetry axis, precess in the direction of rotation with a different angular rate. The proportionality coefficient, or the so-called Bryan ...Read more
Author:Harmse, HF; Britz, K; Gerber, A; Moodley, DDate:Sep 2014One of the challenges in the Software Development Life Cycle (SDLC) is to ensure that the requirements that drive the development of a software system are correct. However, establishing unambiguous and error-free requirements is not a trivial ...Read more
Author:Funke, Nicola S; Claassen, Marius; Nienaber, SDate:Aug 2012The water sector in Southern Africa is uncertain and is changing constantly - there is biophysical uncertainty and the annual rainfall anomalies in Southern Africa between 1901 and 2009 make it difficult to plan. This uncertainty is exacerbated ...Read more
Author:Gibberd, Jeremy T; Mphutlane, LGDate:May 2007This paper describes the School Infrastructure Performance Indicator System (SIPIS) project which explores how an indicator system could be developed for school infrastructure in South Africa. It outlines the key challenges faced by the system ...Read more
Author:Gibberd, Jeremy TDate:Dec 2022With climate change, schools in hot and dry areas are increasingly experiencing water shortages. This can affect the health of students and teachers, disrupt education and in the worst case, lead to school closures. Rainwater harvesting can ...Read more
Author:Van Deventer, ADate:Nov 2008Skills shortages exist in the areas of science and technology, not only in South Africa but globally. Endeavours to address the subsequent need for more people to pursue careers in these disciplines are widespread. We need to ensure that we ...Read more
Author:Van Deventer, ADate:May 2009Skills shortages exist in the areas of Science and Technology, not only in South Africa but globally. This creates a need for more people to follow careers in Science and Technology. We need to do something to make sure that we do not loose ...Read more
