Author:Molose, R; Isong, B; Dladlu, N; Abu-Mahfouz, Adnan MIDate:Jul 2022Energy consumption and the network lifespan of wireless sensor networks (WSNs) are greatly affected by data transmission and retransmission. The challenge follows the energy limitation of sensor nodes with replaceable batteries. Albeit several ...Read more
Author:Olaitan, O; Herselman, Martha E; Wayi, NDate:Jul 2019Background: There are different uses of data in an organisation. Data are required for reporting purposes, decision-making and providing access to vital facts to enable work processes across business units. Data are central to an organisation’s ...Read more
Author:Matusowsky, M; Ramotsoela, DT; Abu-Mahfouz, Adnan MIDate:May 2020Data integrity in wireless sensor networks (WSN) is very important because incorrect or missing values could result in the system making suboptimal or catastrophic decisions. Data imputation allows for a system to counteract the effect of ...Read more
Author:Cooper, Antony KDate:1988Geographical information consists of non-spatial information (alphanumeric) and spatial information (vector and raster), the relationships between the non-spatial information and the spatial information, as well as the spatial relationships ...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: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

The ...Read more
Author:Casini, G; Straccia, UDate:2013Defeasible inheritance networks are a non-monotonic framework that deals with hierarchical knowledge. On the other hand, rational closure is acknowledged as a landmark of the preferential approach to non-monotonic reasoning. We will combine ...Read more
Author:Mashapa, MG; Chetty, N; Ray, Suprakas SDate:May 2012The effect of defect complexes on the stability, structural and electronic properties of single-walled carbon nanotubes and boron nitride nanotubes is investigated using the ab initio pseudopotential density functional method implemented in ...Read more
Author:Pratt, Lawrence E; Govender, Devashen; Klein, RDate:Nov 2021Electroluminescence (EL) images enable defect detection in solar photovoltaic (PV) modules that are otherwise invisible to the naked eye, much the same way an x-ray enables a doctor to detect cracks and fractures in bones. The prevalence of ...Read more
