ENGLISH ABSTRACT : We introduce a method for determining the position of a camera with accuracy beyond that which is obtainable through conventional methods, using a single image of a specially constructed calibration ...

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, ...

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 ...

ENGLISH ABSTRACT : Ocean wave energy can become one of the alternative energy resources for fossil-fuelled power generation in South Africa. Due to global warming, several studies about the generation of wave energy have ...

ENGLISH ABSTRACT : A number of novel hand vein-based biometric authentication systems are proposed. Said systems are non-intrusive and may for example assist with user authentication at automated teller machines. An ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

In the present study, a model to predict the hydrodynamic permeability of viscous flow through an array of solid phase rectangles of any aspect ratio is derived. This also involves different channel widths in the streamwise ...

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 ...

ENGLISH ABSTRACT: Probabilistic graphical models show great promise in resolving uncertainty within large systems by using probability theory. However, the focus is usually on problems with a discrete representation, or ...

ENGLISH ABSTRACT : In order to protect endangered species, such as the Great White shark, a reliable estimate of the population is needed. In counting animals, it is necessary to be able to distinguish between individuals. ...

ENGLISH ABSTRACT : Stream flow is an important component in the hydrological cycle and plays a vital role in many hydrological applications. Accurate stream flow forecasts may be used for the study of various hydro-environmental ...

ENGLISH ABSTRACT : This study aims to establish guidelines for calculating the similarity score between two minutia point representations of ngerprints for minutia-based ngerprint matching. Existing research does not ...

ENGLISH ABSTRACT : In this study we attempt to solve the problem of text detection in natural images. This requires us to identify regions in a natural image that contain text. Possible applications range from assistive ...
