Analysis of Extreme Events in the Coastal Engineering Environment
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT : Coastal zones are subject to storm events and extreme waves with certain return periods. The return period of such events is defined as the average time interceding two independent, consecutive events, ...

Automated elephant detection and classification from aerial infrared and colour images using deep learning
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT : In this study we attempt to detect and classify elephants in aerial images using deep learning. This is not a trivial task even for a human since elephants naturally blend in with their surroundings, making ...

Hydrodynamic permeability of staggered and non-staggered regular arrays of squares
(Stellenbosch : Stellenbosch University, 2003-12)ENGLISH ABSTRACT: This work entails an analysis of two-dimensional Newtonian flow through a prismatic array of squares. Both in-line and staggered configurations are investigated, as well as the very low velocity Darcy ...

Image deblurring and blur kernel estimation of motion blurred colour photographs
(Stellenbosch : Stellenbosch University, 2016-02-23)ENGLISH ABSTRACT : Blurred images can be restored using known deconvolution methods. Image blur can be caused by various factors during the image acquisition phase, such as camera defocus or motion. The restoration of ...

The implementation of the discontinuous Galerkin method for two-dimensional Maxwell equations in Nektar++
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT : Maxwell's equations consist of various laws of electromagnetism and can be written in two different modes in two dimensions: the transverse electric(TE) mode and the transverse magnetic(TM) mode. Various ...
-
Incipient motion of shells and shell fragments
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT : In the present study, the erosion characteristics of shells and shell fragments are investigated. When shells settle, they settle like leaves, where the biggest cross section is exposed to the drag, ...
-
Internal ballistic modelling of solid rocket motors using level set methods for simulating grain burnback
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT : Solid Rocket Motors are propulsive systems providing thrust from products exiting through a nozzle, obtained by burning a solid fuel (the grain) inside a chamber. Various thrust profiles can be obtained ...
-
Investigation of a simplified open boundary condition for coastal and shelf sea hydrodynamic models
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT : In general, coastal and shelf hydrodynamic modelling is undertaken with limited area numerical models such as Delft3D or Mike 21. To conduct successful numerical simulations these programmes require ...

Modelling the South African fresh fruit export supply chain
(Stellenbosch : University of Stellenbosch, 2005-12)ENGLISH ABSTRACT : The process of modelling the fruit export infrastructure capacity of South Africa formed part of a larger project called the Fruit Logistics Infrastructure Capacity Optimisation Study," which was ...
-
Modifying and generalising the Radon transform for improved curve-sensitive feature extraction
(Stellenbosch : Stellenbosch University, 2017-12-01)ENGLISH ABSTRACT : In this thesis a novel and generic feature extraction protocol that is based on the well-known standard discrete Radon transform (SDRT) is presented. The SDRT is traditionally associated with computerised ...
-
Predicting the effect of biofilm growth on the pressure drop over a biofilter
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT : Hydrogen sulphide is a poisonous gas produced by several industries. It is therefore crucial to investigate and mathematically model the environmentally friendly biofiltration process, which has the ...
