Application of cepstral signal processing techniques and a guard tube to the in-situ measurement of the normal incidence sound absorption coefficient by Groll, Neil

“…The work described in this thesis is directed towards the development of a technique for the in situ measurement of the normal incidence sound power absorption coefficient of homogenous materials. The work stemmed from an International Standards Organisation (ISO) working group, ISO/TC 43/SCJ WG38, tasked to formulate a new international standard: " Procedure for measuring sound absorption properties of road surfaces: in-situ method'". …”

Investigating the use of ray tracing for signal-level radar simulation in space monitoring applications: a comparison of radio propagation models by Martin, Mogamat Yaaseen

“…As such, this thesis proposes an open-source, ray-traced radar simulator that models the interactions between spaceborne targets and terrestrial radar systems. This utilises a ray-tracing algorithm to simulate the effects of debris size, shape, orientation, and material properties when computing radar signals in a typical simulation. …”

End-of-life in South African product life cycle assessment by Rodseth, Clare Josephine

“…This result implies that if landfill disposal is modelled over the long-term, the potential impacts of the process has less to do with site-specific conditions than it does to do with the intrinsic properties of the material itself. Given the ensuing extent of degradation that occurs over the time frame considered, the practise of very long-term modelling can equalise landfills that differ strongly in the short-term. …”

Residence time investigation of artificial silver ores in heap leaching using cyanide lixiviant by Gibson, Borbor Auzzel Kwaku Kudar

“…To discern the two patterns the use of a reactive leaching on a well characterized ore material is proposed. Therefore, this work aims to study simultaneously the flow and leach performance of a laboratory column reactor, utilizing a novel reactive leaching approach with a lixiviant amendable to a well-characterized homogeneous solid material. …”
