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
Author:Griffith, DJ; Vhengani, L; Maliage, MDate:Sep 2013Loss of mirror reflectivity due to soiling at Concentrated Solar Power (CSP) plants is a significant consideration for design and operation of the plant. Increasingly, a bankable case for establishment of a new plant will include an evaluation ...Read more
Author:Ostensen, O; O'Brien, D; Cooper, Antony KDate:Feb 2008Natural variability and human influence on climate change are discussed, as well as the ISO Technical Committee ISO/TC 211, Geographic information / Geomatics, who has developed a suite of standards for geographic information that forms a ...Read more
Author:Van der Walt, Christiaan M; Barnard, EDate:Nov 2007The authors study the relationship between the properties of data and classifier performance. Data measures are employed to characterise classification problems and it is shown that these data measures successfully capture important characteristics ...Read more
