Protein kinases play a ...Read more
Author:Botha, N; Kok, S; Inglis, HMDate:Jul 2012Glaucoma is the second leading cause of irreversible blindness. The primary indicator for glaucoma is an elevated intraocular pressure, which is estimated by means of contact or non-contact tonometry. However, these techniques do not accurately ...Read more
Author:Litvin, IA; Forbes, ADate:Aug 2009In this paper the authors present the analytical and numerical analyses of two new resonator systems for generating flat–top–like beams. Both approaches lead to closed form expressions for the required cavity optics, but differ substantially ...Read more
Author:Litvin, IA; Khilo, NA; Forbes, A; Belyi, VNDate:Feb 2010The authors report on two resonator systems for producing Bessel–like beams with longitudinally dependent cone angles (LDBLBs). Such beams have extended propagation distances as compared to conventional Bessel– Gauss beams, with a far field ...Read more
Author:Rens, GB; Varzinczak, IJDate:Dec 2009The authors are developing a new logic (DyMoDeL) for reasoning about dynamic agents with stochastic action, partial observation, knowledge-of and degree-of-belief-in a state of affairs. Development of the syntax and semantics is almost complete, ...Read more

(2007), for purposes of simulating weather at spatial ...Read more
Author:Pattinson, T; Majozi, TDate:2009A novel operational policy, the Process Intermediate Storage operational policy, is introduced and used to synthesize, schedule and design multipurpose batch plants. The model is based on the State Sequence Network and non-uniform discretization ...Read more
Author:Casini, G; Meyer, T; Moodley, K; Sattler, U; Varzinczak, IDate:Oct 2015In recent years, various approaches have been developed for representing and reasoning with exceptions in OWL. The price one pays for such capabilities, in terms of practical performance, is an important factor that is yet to be quantified ...Read more
Author:Van Niekerk, Cornelia W; Pieterse, Amy; Le Roux, AlizeDate:Jan 2020The Green Book is not a book, but a novel, practical online planning tool to support the adaptation of South African settlements to the impacts of climatic changes and severe events. It provides evidence of current and future (2050) climate ...Read more
Author:Stavropoulos, CCDate:Sep 1977The telemetering of information over long distances from unattended environmental monitoring equipment at remote sites can be difficult to carry out using conventional high frequency radio communication. This is because of the need to change ...Read more
