Visualizing the memory performance of parallel programs with Chiron
(1996)
This thesis describes Chiron, visualization system which helps programmers detect memory system bottlenecks in their shared-memory parallel applications. Chiron is different from most other performance debugging tools in ...
Bottom-up evaluation of HiLog in the context of deductive database systems
(1998)
HiLog is a logic-based language which boasts the expressiveness of a higher-order syntax while retaining the simplicity of a first-order semantics. This work examines the suitability of Horn-clause HiLog as a query language ...
Pattern recognition and the nondeterminable affine parameter problem
(1998)
This thesis reports on the process of implementing pattern recognition systems using classification models such as artificial neural networks (ANNs) and algorithms whose theoretical foundations come from statistics. The ...
An efficient parallelization of a real scientific application
(1995)
In the past decade the cost of computing has come down considerably making high-powered computing more easily affordable. As a result many institutions and organisations now have networks of high-powered workstations. Such ...
XSnap : a queueing network analysis package
(1992)
This dissertation describes the design and implementation of a sophisticated X-Windows based modelling package called XSnap, which can be used to solve product-form mixed multi-class queueing networks. A Graphical User ...
HOOD : a Higher-Order Object-Oriented Database model and its implementation
(1992)
There is no accepted standard for the object-oriented database paradigm at present, which has led to different definitions of features and conformance requirements. HOOD is a Higher-Order Object-Oriented Database system ...
Generalised Markovian analysis of timed transition systems
(1996)
This dissertation concerns. analytical methods for assessing the performance of concurrent systems. More specifically, it focuses on the efficient generation and solution of large Markov chains which are derived from models ...
Information visualisation
(1996)
Information visualisation uses interactive three-dimensional (3D) graphics to create an immersive environment for the exploration of large amounts of data. Unlike scientific visualisation, where the underlying physical ...
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 ...
