Refactoring learning management systems for multi-device use in developing countries
(2015)
Although learning management systems (LMSs) have been widely adopted by universities in developing countries, their potential to support students' learning has not been fully exploited due to several factors. Some of the ...
Scaffolding java programming on a mobile phone for novice learners
(2015)
The ubiquity of mobile phones provides an opportunity to use them for learning programming beyond the classroom. This would be particularly useful for novice learners of programming in resource- constrained environments. ...
Accelerating radio transient detection using the Bispectrum algorithm and GPGPU
(2015)
Modern radio interferometers such as those in the Square Kilometre Array (SKA) project are powerful tools to discover completely new classes of astronomical phenomena. Amongst these phenomena are radio transients. Transients ...
Determining the optimal protocols for transfer of large data files
(2015)
The transfer of large data files remains a necessity for scientific research, including Bioinformatics, despite alternate solutions like cloud computing. When transferring large files, there are many transfer protocols to ...
An empirical evaluation of evolutionary controller design methods for collective gathering task
(2015)
This research aims to evaluate the performance of evolutionary controller design methods for developing a collective behaviour for a team of robots. The methods tested in this research are NEAT which is capable of finding ...
Access and information flow control to secure mobile web service compositions in resource constrained environments
(2015)
The growing use of mobile web services such as electronic health records systems and applications like twitter, Facebook has increased interest in robust mechanisms for ensuring security for such information sharing services. ...
Integrating contextmapping and interaction design: designing with and for small-scale urban farmers in Soweto
(2015)
This thesis describes and reflects on the effectiveness of integrating contextmapping as both a methodology and interaction design practice in order to co-design digital products with and for developing communities. A ...
Designing mobile multi-touch drum sequencing applications
(2015)
Digital music software can limit the forms of music we create by using interfaces that directly copy those of the analogue instruments that came before. In this study we report on a new multi-touch interface that affords ...
Advancing security information and event management frameworks in managed enterprises using geolocation
(2015)
Security Information and Event Management (SIEM) technology supports security threat detection and response through real-time and historical analysis of security events from a range of data sources. Through the retrieval ...
Acceleration of the noise suppression component of the DUCHAMP source-finder
(2015)
The next-generation of radio interferometer arrays - the proposed Square Kilometre Array (SKA) and its precursor instruments, The Karoo Array Telescope (MeerKAT) and Australian Square Kilometre Path finder (ASKAP) - will ...
