In this dissertation, we explore methods for empowering non-programmers with the ability to develop their own virtual environment applications. We explored some of the existing systems to determine what methodologies have ...

In this work, we describe a Graphics processing unit (GPU) implementation of the Kim-Hummer coarse-grained model for protein docking simulations, using a Replica Exchange Monte-Carlo (REMC) method. Our highly parallel ...

This study has shown that modelling and simulation is a feasible approach for evaluating NPR solutions in the developing context. The model can represent different network models, patient types and performance metrics to ...

This thesis situates digital storytelling in rural African communities to enable rural people to record and share their stories and to express their imaginations digitally. We explore the role of design and the methods and ...

Cultures evolve continuously, and it is therefore vital to track and record these changes, and most importantly of all, manage the resulting huge mass of data such as images, video clips, audio recordings and documents. ...

Currently, the standard approach to visibility preprocessing algorithms is to use a form of approximate solution, known as conservative culling. Such algorithms over-estimate the set of visible polygons. This compromise ...

Many universities, libraries, government organisations and companies are implementing digital repositories to collect, preserve, administer and distribute their collections via the World Wide Web. In the process of building ...

The main objective of this thesis is to provide content creators and educators with a solution that simplifies the process of depositing into digital repositories. We created a desktop tool named ORchiD, Open educational ...

The last decades have witnessed the emergence of a large number of devices pervasively launched into our daily lives as systems producing and collecting data from a variety of information sources to provide different ...

The cerebellum is known to be very susceptible to prenatal exposure to alcohol and people affected by Fetal Alcohol Spectrum Disorder (FASD) show a decrease in cerebellar volume. Unfortunately, there seems to be little ...

Universities in developing nations are viewed as gateways to global knowledge and as the source of human capital for their countries' economies (Juma, 2008). However, these universities face challenges in accessing educational ...

Recording university lectures through lecture capture systems is increasingly common. However, a single continuous audio recording is often unhelpful for users, who may wish to navigate quickly to a particular part of a ...

Trust assurances for customers of online transactions is an important, but not well implemented concept for the growth of confidence in electronic transactions. In an online world where customers do not personally know the ...

Terrain synthesis is an important field of Computer Graphics that deals with the generation of 3D landscape models for use in virtual environments. The field has evolved to a stage where large and even infinite landscapes ...

Many motion tracking systems average and integrate tracking measurements over a period of time in order to reduce the effects of device noise, external noise and other disturbances. The target (user) is likely to be ...

There are a growing number of mobile phones being used in developing contexts, such as Africa. A large percentage of these phones have the capability to take photographs and transmit them freely using Bluetooth. In order ...

Traceability is a critical software engineering practice that manages activities across the product development lifecycle. It is the discipline of getting an entire organisation to work together to build better quality ...

Our initial study indicates that successful integration of new communication medium into South African schools is not only challenging from the financial point of view, but also in terms of designing tools that fit within ...

The phenomenal emergence of several heterogeneous wireless networks and technologies has allowed users to have access to IP services anywhere, at anytime, from any network and with whatever terminal they use. This computing ...

The skill of accurately predicting the optimal time to buy or sell shares on the stock market is one that has been actively sought by both experienced and novice investors since the advent of the stock exchange in the early ...
