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 ... -
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 ... -
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 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 ... -
A study of evoluntionary perturbative hyper-heuristics for the nurse rostering problem.
(2017)Hyper-heuristics are an emerging field of study for combinatorial optimization. The aim of a hyper-heuristic is to produce good results across a set of problems rather than producing the best results. There has been little ... -
A study of genetic algorithms for solving the school timetabling problem.
(2013)The school timetabling problem is a common optimization problem faced by many primary and secondary schools. Each school has its own set of requirements and constraints that are dependent on various factors such as the ... -
A study of genetic programming and grammatical evolution for automatic object-oriented programming.
(2016)Manual programming is time consuming and challenging for a complex problem. For efficiency of the manual programming process, human programmers adopt the object-oriented approach to programming. Yet, manual programming is ... -
A support environment for the teaching of programming.
(1996)This thesis examines the effectiveness of a specially constructed computer based support environment for the teaching of computer programming to novice programmers. In order to achieve this, the following distinct ... -
Techniques and countermeasures of TCP/IP OS fingerprinting on Linux Systems
(2007)Port scanning is the first activity an attacker pursues when attempting to compromise a target system on a network. The aim is to gather information that will result in identifying one or more vulnerabilities in that system. ... -
Unsupervised caries detection in non-standardized bitewing dental X-Rays.
(2017)In recent years dental image processing has become a useful tool in aiding healthcare professionals diagnose patients by reducing some of the problems inherent with dental radiographs. Despite advances in the eld, ... -
Using mobile agents to solve the distributed buying problem.
(2002)This study deals with the Distributed Buying Problem, that is, the problem faced by geographically distributed businesses when it comes to optimising buyer time and global businesses resources. It adopts a software ...
