Adoption of a visual model for temporal database representation
(2016)
Today, in the world of information technology, conceptual model representation of database schemas is challenging for users both in the Software Development Life Cycle (SDLC) and the Human-Computer Interaction (HCI) domain. ...
Accelerated deconvolution of radio interferometric images using orthogonal matching pursuit and graphics hardware
(2016)
Deconvolution of native radio interferometric images constitutes a major computational component of the radio astronomy imaging process. An efficient and robust deconvolution operation is essential for reconstruction of ...
Parallelisation of algorithms
(1990)
Most numerical software involves performing an extremely large volume of algebraic computations. This is both costly and time consuming in respect of computer resources and, for large problems, often super-computer power ...
Automating user privacy policy recommendations in social media
(2016)
Most Social Media Platforms (SMPs) implement privacy policies that enable users to protect their sensitive information against privacy violations. However, observations indicate that users find these privacy policies ...
Softbridge : a socially aware framework for communication bridges over digital divides
(2009)
Computer scientists must align social and technical factors for communication technologies in developing regions yet lack a framework to do so. The novel Softbridge framework comprises several components to address this ...
Using access information in the dynamic visualisation of web sites
(2004)
Log file analysis provides a cost-effective means to detennine web site usage. However, current methods of displaying log analysis results tend to be limited in that they either contain no reference to a web site's structure, ...
Anomaly detection and prediction of human actions in a video surveillance environment
(2007)
World wide focus has over the years been shifting towards security issues, not in least due to recent world wide terrorist activities. Several researchers have proposed state of the art surveillance systems to help with ...
Providing informational support to HIV + women in a virtual environment : a case study comparing the effects of virtual reality and paper media for content delivery
(2008)
This dissertation presents a comparison of the effects of two media, VR and paper (i.e. pamphlets) in communicating supportive information to an HIV+ sample group. We created a VE to provide social and informational support ...
Using formalised floor-plans in the design and creation of virtual environments
(2005)
Virtual Reality (VR) is an new and exciting medium waiting to be fully explored and capitalised by media experts. The advantages of the 3D graphics andinteractive nature of VR allows unique communication opportunities from ...
