  • Akpakwu, GA; Hancke, GP; Silva, BJ; Abu-Mahfouz, Adnan (IEEE, 2016-07)
    The concept of data distribution within cluster of sensor nodes to the source sink has resulted to intense research in Wireless Sensor Networks (WSNs). In this paper, in order to determine the scheduling length of packet ...
  • Freiboth, H; Goedhals-Gerber, LL; van Dyk, E; Dodd, M (LM-SCM 2014 XII. International Logistics and Supply Chain Congress, 2014-10)
    A large amount of fruit and money is lost every season due to breaks in the South African fruit export cold chain. With food security becoming an ever growing concern, especially in developing countries like South Africa, ...
  • Gerrand, Jonathan D; Williams, Quentin R; Lunga, D; Pantanowitz, A; Madhi, S; Mahomed, N (Springer, 2017-07)
    Within developing countries, there is a realistic need for technologies that can assist medical practitioners in meeting the increasing demand for patient screening and monitoring. To this end, computer aided diagnosis ...
  • Forbes, A; Du Preez, NC; Belyi, VN; Botha, LR (Society of Photo-Optical Instrumentation Engineers, 2009-08)
    In this paper the researchers present results on improved paint stripping performance with an intra-cavity generated Flattened Gaussian Beam (FGB). A resonator with suitable diffractive optical elements was designed in ...
  • Modibedi, RM; Ozoemena, KI; Mathe, MK (Springer, 2013)
    Direct alcohol alkaline fuel cells (DAAFCs) are potential power sources for a variety of portable applications as they provide unique advantages over hydrogen-based fuel cell devices. Alcohols (such as methanol, ethanol, ...
  • Zeevaart, JG; Parkinson, CJ; De Koning, CB (Pergamon-Elsevier Science Ltd, 2004-05-24)
    The coupling reaction between ethyl acetoacetate and a number of aryl halides in the presence of palladium acetate, a bulky and electron rich phosphine and K3PO4 is described. The arylated acetoacetate ester is de-acylated ...
  • Zeevaart, JG; Parkinson, CJ; De Koning, CB (Pergamon-Elsevier Science Ltd, 2005-03-07)
    Alpha-Arylation of inethanesulfonamides using palladium catalysis is described. For example, treatment of N-benzyl-Nmethylmethanesulfonamide with catalytic Pd (OAc) (2) in the presence of sodium tert-butoxide, triphenylphosphine ...
  • Henriques, R; Griffiths, C; Rego, EH; Mhlanga, MM (Wiley Blackwell, 2011-05)
    Live-cell fluorescence light microscopy has emerged as an important tool in the study of cellular biology. The development of fluorescent markers in parallel with super-resolution imaging systems has pushed light microscopy ...
  • Henriques, R; Mhlanga, MM (Wiley-VCH Verlag Berlin, 2009-06)
    Super-resolution imaging allows the imaging of fluorescently labeled probes at a resolution of just tens of nanometers, surpassing classic light microscopy by at least one order of magnitude. Recent advances such as the ...
  • Clarke, BC (CSIR, National Research Institute for Oceanology, 1989-03)
    This report was prepared as a result of a research undertaken in both the catchment and the estuary. The prime motivation for this work has been the need to estimate the impact of the dams on the ecology of the river and ...
  • Burke, Michael G; Lasenby, J (IEEE Xplore, 2015-10)
    This paper introduces a pantomimic gesture interface, which classifies human hand gestures using unmanned aerial vehicle (UAV) behavior recordings as training data. We argue that pantomimic gestures are more intuitive than ...
  • Govindasamy, K; Potgieter, S; Kumar, S; Land, K; Muzenda, E (2012-09)
    Microfluidics has found widespread application in the fields of molecular biology, DNA analysis and most recently, point of care diagnostics. We present a paper based microfluidic device for rapid, in-the-field detection ...
  • Smith, S; Moodley, K; Govender, Ureshnie; Chen, H; Fourie, L; Ngwenya, S; Kumar, S; Mjwana, P; Cele, H; Mbanjwa, MB; Potgieter, S; Joubert, T-H; Land, K (Academy of Science of South Africa (ASSAf), 2015-11)
    Current centralised healthcare models pose many challenges, particularly for developing countries such as South Africa, where travel and time costs make it difficult for patients to seek healthcare, even when urgently ...
  • Wiederoder, MS; Smith, S; Madzivhandila, P; Mager, D; Moodley, K; DeVoe, DL; Land, KJ (2016-10)
    This study describes a novel hybrid paper-polymer centrifugal microfluidic device for pre-concentration of E.coli and lateral flow immunoassay enhancement for water quality verification. The device balances rotational ...
  • Ibrahim, AH; Roux, FS; Konrad, T (American Physical Society, 2014-11)
    When a pair of photons that are entangled in terms of their transverse modes, such as an orbital angular momentum (OAM) basis, propagates through atmospheric turbulence, the scintillation causes a decay of the entanglement. ...
  • Hamadou Ibrahim, A; Roux, FS; Konrad, T (SPIE, 2011-08)
    he orbital angular momentum (OAM) state of light can potentially be used to implement higher dimensional entangled systems for quantum communication. Unfortunately, optical fibers in use today support only modes with zero ...
  • Bidgood, Peter M; Nel, AL (2013-09)
    The current trend in balance calibration-matrix generation is to use non-linear regression and statistical methods. Methods typically include Modified-Design-of-Experiment (MDOE), Response-Surface-Models (RSMs) and Analysis ...
  • Adebiyia, DI; Fatoba, O; Pityana, S; Popoola P (The 30th International Conference on Surface Modification Technologies, 2016-06)
    Silicon carbide (SiC), has excellent mechanical properties such as high hardness and good wear resistance, and would have been a suitable laser-coating material for titanium alloy to enhance the poor surface hardness of ...
  • Klein, P; Roos, TH; Sheer, TJ (2015-08)
