Author:Cichowicz, ADate:Mar 2001A set of data, collected from Mponeng and East Driefontein mines, provides a new insight into the response of support unit under seismic load. The most important accomplishment of monitoring is the measurement of peak ground acceleration ...Read more
Author:Dzikiti, Sebinasi; Jovanovic, Nebojsa; Bugan, Richard DH; Israel, S; Le Maitre, David CDate:Apr 2014Many studies have investigated the water relations of indigenous plants in the fynbos shrublands of the Cape, South Africa. These have mainly focused on understanding the mechanisms by which individual plant species respond to droughts, the ...Read more
Author:De Saxe, Christopher C; Cebon, DCDate:Mar 2019Articulated heavy goods vehicles and long combination vehicles offer improved efficiency and emissions but reduced low-speed manoeuvrability and high-speed stability compared to rigid lorries. Active control systems can help to address these ...Read more
Author:Griffith, DJ; Le Roux, FPJ; Schwering, PBW; Holloway, MDate:Sep 2008Measurement of atmospheric modulation transfer function (MTF) derived from the point spread function is an alternative to the use of scintillometry in characterizing the effects of turbulence as well as optical scattering. This experiment ...Read more

Author:De Koker, PM; Pavkovic, N; Van Dyk, JT; Stecker, IDate:Sep 2009The impulse generated by the detonation of anti-tank mines is an important characteristic of the mine used to design and develop protective countermeasures and to define the threat in terms of scientific and engineering terms. CSIR in ...Read more
Author:Mgangira, Martin B; Anochie-Boateng, Joseph; Koen, Renée; Komba, Julius J; Tutumluer, EDate:Jan 2016Aggregate shape properties are used to characterize aggregate product from quarry operations. However, aggregate shape depends on rock type and crushing process. A meta-quartzite, a relatively low grade thermal metamorphic rock was crushed ...Read more
Author:Andrew, J; Hanuman, A; Sithole, Bishop BDate:Jan 2011Contaminants from synthetic polymers such as plastics, coatings, adhesives and waxes remain one of the biggest challenges for papermakers using recovered fibre. These contaminants are called “stickies” because they stick to paper machine felts ...Read more

Author:Schulze, C; Dudley, Angela L; Brüning, R; Duparré, M; Forbes, ADate:Sep 2014We present the measurement of the orbital angular momentum (OAM) density of Bessel beams and superpositions thereof by projection into a Laguerre–Gaussian basis. This projection is performed by an all-optical inner product measurement performed ...Read more
Author:Schulze, C; Dudley, Angela L; Flamm, D; Duparre, M; Forbes, ADate:Jul 2013We demonstrate a versatile method for the measurement of the orbital angular momentum (OAM) density of an optical field. By performing a modal decomposition with digital holograms, we reconstruct the full optical field from a small set of ...Read more
Author:Andrew, J; Hanuman, ADate:Oct 2010Contaminants from adhesives and waxes remain one of the biggest challenges for papermakers using recovered fibre. These contaminants are called “stickies” because they stick to papermachine felts and wires leading to operating problems, reduced ...Read more
Author:Moes, JDate:Jun 2007This paper presents a description of a decision support system for ship draught allowance, in operation at the Port of Richards Bay, South Africa. This system is partially based on small-scale and numerical model tests, which were verified ...Read more
Author:Mosikare, OR; Theron, NJ; Van de Molen, WDate:Sep 2010The Response Amplitude Operator (RAO) theory was used to develop a mathematical model of boat angular motion. Measurements were made on a harbour patrol boat on sea runs off Durban Harbour. Measurements were first calibrated for axis alignment ...Read more
