On case representation and indexing in a case-based reasoning system for waste management.
(1997)Case-Based Reasoning is a fairly new Artificial Intelligence technique which makes use of past experience as the basis for solving new problems. Typically, a case-based reasoning system stores actual past problems and ... -
On common fixed points approximation of countable families of certain multi-valued maps in hilbert spaces.
(2017)Fixed point theory and its applications have been widely studied by many researchers. Di erent iterative algorithms have been used extensively to approximate solutions of xed point problems and other related problems ... -
On modeling and optimisation of air Traffic flow management problem with en-route capacities.
(2016)The air transportation industry in the past ten years witnessed an upsurge with the number of passengers swelling exponentially. This development has seen a high demand in airport and airspace usage, which consequently ... -
On the performance of metaheuristics for the blood platelet production and inventory problem.
(2016)Abstract available in PDF file. -
On the sample consensus robust estimation paradigm: comprehensive survey and novel algorithms with applications.
(2016)This study begins with a comprehensive survey of existing variants of the Random Sample Consensus (RANSAC) algorithm. Then, five new ones are contributed. RANSAC, arguably the most popular robust estimation algorithm in ... -
Ontology driven multi-agent systems : an architecture for sensor web applications.
(2009)Advances in sensor technology and space science have resulted in the availability of vast quantities of high quality earth observation data. This data can be used for monitoring the earth and to enhance our understanding ... -
An ontology-driven approach for structuring scientific knowledge for predicting treatment adherence behaviour: a case study of tuberculosis in Sub-Saharan African communities.
(2016)Poor adherence to prescribed treatment is a complex phenomenon and has been identified as a major contributor to patients developing drug resistance and failing treatment in sub-Saharan African countries. Treatment adherence ... -
The open health information mediator : an architecture for enabling interoperability in low to middle income countries.
(2015)Interoperability and system integration are central problems that limit the effective use of health information systems to improve efficiency and effectiveness of health service delivery. There is currently no proven ... -
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 ...
