Packing problems on a PC.
(1991)Bin packing is a problem with many applications in various industries. This thesis addresses a specific instance of the this problem, known as the Container Packing problem. Special attention is paid to the Pallet Loading ... -
Planarity testing and embedding algorithms.
(1990)This thesis deals with several aspects of planar graphs, and some of the problems associated with non-planar graphs. Chapter 1 is devoted to introducing some of the fundamental notation and tools used in the remainder of ... -
A practical investigation of meteor-burst communications.
(1991)This study considers the meteor-burst communication (MBC) environment at three levels. At the lowest level, the trails themselves are studied and analysed. Then individual links are studied in order to determine the data ... -
Practical reasoning for defeasable description logics.
(2016)Description Logics (DLs) are a family of logic-based languages for formalising ontologies. They have useful computational properties allowing the development of automated reasoning engines to infer implicit knowledge ... -
Q-Cog: a Q-Learning based cognitive agent architecture for complex 3D virtual worlds.
(2017)Intelligent cognitive agents should be able to autonomously gather new knowledge and learn from their own experiences in order to adapt to a changing environment. 3D virtual worlds provide complex environments in which ... -
Qualitative and structural analysis of video sequences.
(2011)This thesis analyses videos in two distinct ways so as to improve both human understanding and the computer description of events that unfold in video sequences. Qualitative analysis can be used to understand a scene in ... -
RAT online : design, delivery and evaluation of constructivist computer supported martial arts learning environments.
(2011)This thesis describes the evaluation of several computer supported martial arts learning environments. These learning environments were designed, developed and implemented for practitioners of Rough and Tumble (RAT), a ... -
A real time, system independent, secure, Internet based auctioning system.
(2000)This thesis outlines the creation of a secure, real time, system independent, Internet based auctioning application. The system has been developed to meet the needs of today's stringent reqUirements on secure Internet ... -
Relieving the cognitive load of constructing molecular biological ontology based queries by means of visual aids.
(2007)The domain of molecular biology is complex and vast. Bio-ontologies and information visualisation have arisen in recent years as means to assist biologists in making sense of this information. Ontologies can enable the ... -
Satellite remote sensing of particulate matter and air quality assessment in the Western Cape, South Africa.
(2016)Particulate Matter (PM) is a health risk, even at low ambient concentrations in the atmosphere. The analysis of ambient PM is important in air quality management in South Africa in order to suggest recommendations for ... -
A semantic sensor web framework for proactive environmental monitoring and control.
(2017)Observing and monitoring of the natural and built environments is crucial for main- taining and preserving human life. Environmental monitoring applications typically incorporate some sensor technology to continually ... -
Settlement type classification using aerial images.
(2014)In metropolitan and urban areas, the problems relating to rapid transformations that are taking place in terms of land cover and land use are now very pronounced, e.g., the rapid increase and unpredictable spread of ... -
Shot classification in broadcast soccer video.
(2013)Event understanding systems, responsible for automatically generating human relatable event descriptions from video sequences, is an open problem in computer vision research that has many applications in the sports domain, ... -
Specifying a forest harvest scheduling system which includes wood properties.
(2009)This dissertation aims to specify a forest harvest scheduling system which includes wood properties in the harvesting decisions for the long-term (strategic) planning horizon. This system will be used by plantation ... -
Spectral techniques for roughness estimation.
(2001)Roughness is a relatively untouched field considering its significance to natural scientists. In this thesis mathematical techniques for measuring the roughness of signals are constructed and investigated. Both one ... -
Speech recognition and blackboard expert systems.
(1992)Spoken language is used by people to communicate naturally with one another. A simplistic view of the communication process is as follows. Person A wishes to communicate an idea to person B. The idea, initiated in the ... -
Studies in heuristics for the annual crop planning problem.
(2012)Increase in the costs associated with agricultural production and the limited availability of resources have amplified the need for optimized solutions to the problem of crop planning. The increased costs have imparted ... -
Studies in particle swarm optimization technique for global optimization.
(2013)Abstract available in the digital copy. -
Studies of heuristics for hostel space allocation problem.
(2013)This research work focused on the performance of heuristics and metaheuristics for the recently defined Hostel Space Allocation Problem (HSAP), a new instance of the space allocation problem (SAP) in higher institutions ...
