This project aims to find the minimum video resolution and frame rate that supports intelligible cell phone based video communications in South African Sign Language.
Web-based management of time-series raster data
Data discovery and data handling often presents serious challenges to organizations that manage huge archives of raster datasets such as those generated by satellite remote sensing. Satellite remote sensing produces a ...
An efficient management system for large digital object collections
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. ...
Expert system adjudication of hospital data in HIV disease management
HIV Disease Management Programs (DMP's) are comprehensive programs that are designed to manage the HIV infected patient's treatment in an integrated manner.
Understanding merchant adoption of m-payments in South Africa
Despite the proliferation of mobile communication technology and smartphone adoption, a number of barriers, most notably trust and security, and the lack of critical mass, have slowed the uptake of mobile payments (m-payments). ...
Help or hindrance? : an investigation into learning through web interfaces
A usability study was designed with these issues in mind, to determine the influence of interface design on learning in an educational institution in Namibia. A pilot study identified obstacles and served to enhance the ...
Measuring the applicability of open data standards to a single distributed organisation : an application to the COMESA Secretariat
This dissertation develops data metrics that represent the extent to which data standards can be applied to an organization's data. The research identified key issues that affect data interoperability or the feasibility ...
Can health workers capture data using a generic mobile phone with sufficient accuracy for Capture at Source to be used for clinical research purposes?
Objective: To determine the accuracy, measured by error rate, with which Clinical Research Workers (CRWs), with minimal experience in data entry, could capture data on a feature phone during an interview using two different ...
Semi-automatic matching of semi-structured data updates
Data matching, also referred to as data linkage or field matching, is a technique used to combine multiple data sources into one data set. Data matching is used for data integration in a number of sectors and industries; ...
Force field comparison through computational analysis of capsular polysaccharides of Streptococcus pneumoniae serotypes 19A and F
Modern Molecular Dynamics force fields, such as the CHARMM36 and GLYCAM06carbohydrate force fields, are parametrised to reproduce behaviours for specific molecules under specific conditions in order to be able to predict ...
