Graphics processing unit accelerated coarse-grained protein-protein docking
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...

A simulation model for evaluating national patient record networks in South Africa.
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2012)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 ...

Designing digital storytelling for rural African communities
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...

An efficient management system for large digital object collections
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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. ...

Fast and accurate visibility preprocessing
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2003)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 ...
-
Large image support in digital repositories
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2010)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 ...
-
An end to end solution for complex open educational resources
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2012)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 ...
-
Situation recognition using soft computing techniques
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2012)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 ...

Tissue segmentation of the cerebellum from MR images
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...

Adapting a novel public display system for an educational context
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2010)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 ...

Improving searchability of automatically transcribed lectures through dynamic language modelling
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2012)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 ...
-
A transaction assurance framework for web services
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2007)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 ...

Distributed texture-based terrain synthesis
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...
-
Uncertain input estimation with application to Kalman tracking
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...
-
Mobile media distribution in developing contexts
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2011)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 ...
