Depth discrimination of an acoustic source based on modal energy distribution
The new method of acoustic source depth discrimination in a shallow water environment is investigated. The investigation is concentrated mainly in 500Hz and 1kHz sources in the range-independent and range-dependent environments. Efficiency and robustness of the method is studied and suggestions for …

High performance photon-pair source based on a fiber-coupled periodically poled KTiOPO₄ waveguide
Photon-pair sources based on spontaneous parametric downconversion (SPDC) in a nonlinear crystal waveguide have been shown to be significantly more efficient than those in a bulk crystal. To utilize waveguide sources in quantum information processing (QIP) applications, it is highly desirable to …

Does South Africa have a coherent policy for source-based taxation based on the permanent establishment concept, and how has this policy been implemented in its bilateral tax treaties?
… South Africa has a coherent PE policy for source-based taxation. In addressing this question, this thesis considered what South Africa’s PE negotiating policy is and identified trends in its tax treaty practice in order to determine any inconsistency with its domestic PE definition. The key …

An evaluation of the adequacy of the existing framework for source-based taxation in South Africa as applied to the new business models proliferated by the digitalisation of the economy
… of the existing South African framework for source-based taxation in its application to the new digitalised business models. Primarily, it is established that the ‘benefit theory' provides the theoretical justification for the imposition of tax on the basis of source, and therefore provides …
