The efficient evaluation of visual queries within a logic-based framework
(1995)
There has been much research in the area of visual query systems in recent years. This has stemmed from the need for a more powerful database visualization and querying ability. In addition, there has been a pressing need ...
Spline wavelet image coding and synthesis for a VLSI based difference engine
(1994)
The efficiency of an image compression/synthesis system based on a spline multi-resolution analysis (MRA) is investigated. The proposed system uses a quadratic spline wavelet transform combined with minimum-mean squared ...
Participatory cloud computing : the community cloud management protocol
(2014)
This thesis work takes an investigative approach into developing a middleware solution for managing services in a community cloud computing infrastructure pre-dominantly made of interconnected low power wireless devices. ...
Analytical performance evaluation of concurrent communicating systems using SLD and stochastic Petri nets
(1997)
In this thesis, the performance analysis of SDL with a new type of stochastic Petri net is described. This new net is called SDL-net. The Concurrent Communicating System is described, and the need for qualitative and ...
The influence of protocol choice on network performance
(1995)
Computer communication networks are a vital link in providing many of the services that we use daily, and our reliance on these networks is on the increase. The growing use of networks is driving network design towards ...
A workflow for geocoding South African addresses
(2015)
There are many industries that have long been utilizing Geographical Information Systems (GIS) for spatial analysis. In many parts of the world, it has gained less popularity because of inaccurate geocoding methods and a ...
Visualizing the performance of parallel programs
(1996)
The performance analysis of parallel programs is a complex task, particularly if the program has to be efficient over a wide range of parallel machines. We have designed a performance analysis system called Chiron that ...
Procedurally generating surface detail for 3D models using voxel-based cellular automata
(2016)
Procedural generation is used extensively in the field of computer graphics to automate content generation and speed up development. One particular area often automated is the generation of additional colour and structural ...
Multitouch-based collaborative pre-visualisation for computer animation
(2016)
Computer animated pre-visualisation occurs at an early stage of visualising scenes in low-fidelity. This is a collaborative process, in which directors communicate with animators how shot sequences will occur. Producers ...
Accelerated coplanar facet radio synthesis imaging
(2016)
Imaging in radio astronomy entails the Fourier inversion of the relation between the sampled spatial coherence of an electromagnetic field and the intensity of its emitting source. This inversion is normally computed by ...
