Author:Cull, T; Vincent, K; Davis, C; Archer, Emma RMDate:Nov 2011This chapter is concerned with how we can respond to climate change in order to reduce its adverse impacts. Following international practice, these responses can broadly be grouped into mitigation (reduction in the causes of climate change) ...Read more

Author:Carter-Brown, ClintonDate:Jul 2017Future energy systems will largely be based on Distributed Energy Resources (DER) –a combination of VRE, storage and demand response technologies. Technology and systems innovations are required to design, build and operate such energy systems ...Read more
Author:Olwal, TO; Van Wyk, BJ; Djouani, K; Hamam, Y; Siarry, P; Ntlatlapa, Ntsibane SDate:Sep 2010Multi-Radio Multi-Channel (MRMC) WMNs result in power control problems including interference, un-scalable connectivity and energy consumption. Several previous studies have focused on the single radio wireless configurations while studying ...Read more
Author:Lehmann, CER; Archibald, SA; Hoffmann, WA; Bond, WJDate:Jul 2011We aimed to identify the limits of savanna across Africa, Australia and South America. We based our investigation on the rich history of hypotheses previously examined; that the limits of savanna are variously determined by rainfall, rainfall ...Read more
Author:Steenkamp, Lucia H; Brady, DDate:Jun 2010The non-steroidal anti-inflammatory drug naproxen is most effective as the single S-naproxen enantiomer. However, typical synthetic routes to naproxen yield the racemate of both the R and the S stereoisomers. Biocatalysts can be used to resolve ...Read more
Author:Van der Merwe, A; Van Dyk, FE; Van Vuuren, JHDate:Dec 2011Recent technological advances have had a major impact on the management of traditional wineries, giving rise to the prospect of computerised decision support with respect to a range of complex harvesting and wine making decisions which have ...Read more
Author:Van Der Merwe, A; Van Dyk, E; Van Vuuren, JDate:Sep 2007The goal of the study is to lend decision support to management a a wine cellar in three areas of expertise, with Wamakersvallei Winery serving as a special case study. This decision support system is to be delivered in the form of Excel ...Read more
Author:Meyer, IA; Marais, Mario ADate:Oct 2014A number of factors complicate the ability to deliver sustainably on development interventions. Multiple role players are involved, the performance of implementation agencies are measured over the short- to medium term and donors do not always ...Read more
Author:Lanz, EJ; Van Dyk, FE; Van Vuuren, JHDate:Sep 2011The mission of the Global Foodbanking Network is to work together to alleviate world hunger by developing national networks of foodbanks and strengthening foodbanking around the world. In the South African context, the goal of the foodbank ...Read more
Author:Turpin, SM; Marais, Mario ADate:2004This paper compares a number of theoretical models of decision-making with the way in which senior managers make decisions in practice. Six prominent decision-makers were interviewed about their own decision-making style as well as their use ...Read more
Author:Uys, H; Biercuk, MJ; VanDevender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJDate:Nov 2010The authors present theoretical and experimental studies of the decoherence of hyperfine ground-state superpositions due to elastic Rayleigh scattering of light off resonant with higher lying excited states. They demonstrate that under ...Read more
Author:Uys, H; Biercuk, M; Van Devender, AP; Ospelkaus, C; Meiser, D; Ozeri, R; Bollinger, JJDate:Sep 2010This paper investigates the decoherence of superpositions of hyperfine states of 9Be+ ions due to spontaneous scattering of off-resonant light. It was found that, contrary to conventional wisdom, elastic Raleigh scattering can have major ...Read more
Author:Roux, FSDate:Jun 2012This report present the presentation on deconstructing quantum decoherence in atmospheric turbulence. The focus was on the classical and quantum scintillation, time vs propagation distance, current paradigm: Paterson model, infinitesimal ...Read more
Author:Ndlovu, GF; Asante, JKO; Roos, WD; Hillie, KTDate:Jul 2011An Ultra-high Vacuum Variable Temperature Scanning Tunnelling Microscope was used to study the growth mechanism of Antimony on vicinal Cu polycrystalline samples. The STM data after deposition of 0.3 ML Sb at 300°C showed localization of Sb ...Read more
Author:Cronje, JDate:Nov 2015The work in this paper address the problem of removing non-uniform motion blur from a single image. The motion vector for an image patch is estimated by using a convolutional neural network (CNN). All the predicted motion vectors are combined ...Read more
