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 ... 
The paradigms of mechanics : a symmetry based approach.
(1996)An overview of the historical developments of the paradigms of classical mechanics, the free particle, oscillator and the Kepler problem, is given ito (in terms of) their conserved quantities. Next, the orbits of the three ... 
Parameters related to fractional domination in graphs.
(1995)The use of characteristic functions to represent wellknown sets in graph theory such as dominating, irredundant, independent, covering and packing sets  leads naturally to fractional versions of these sets and corresponding ... 
Partial exchangeability and related topics.
(1991)Partial exchangeability is the fundamental building block in the subjective approach to the probability of multitype sequences which replaces the independence concept of the objective theory. The aim of this thesis is ... 
A perspective on incomplete data in longitudinal multiarm clinical trials, with emphasis on patternmixturemodel based methodology.
(2014)Missing data are common in longitudinal clinical trials. Rubin described three different missing data mechanisms based on the level of dependence between the missing data process and the measurement process. These are ... 
Planarity testing and embedding algorithms.
(1990)This thesis deals with several aspects of planar graphs, and some of the problems associated with nonplanar graphs. Chapter 1 is devoted to introducing some of the fundamental notation and tools used in the remainder of ... 
Possible Models Diagrams: a new approach to teaching propositional logic.
(1994)Abstract available in PDF. 
A practical investigation of meteorburst communications.
(1991)This study considers the meteorburst 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 logicbased languages for formalising ontologies. They have useful computational properties allowing the development of automated reasoning engines to infer implicit knowledge ... 
Prevalence and risk factors associated with malaria infection in children under the age of fourteen years in Kenya.
(2017)Despite various efforts by multilateral agencies and governments to prevent, control and eliminate malaria, it continues to be a major plague with more than 300 million at risk of infection worldwide. In Kenya, it is still ... 
Prevalence and risk factors of malaria in children under the age of five years old in Uganda.
(2015)Malaria is considered to be one of the main global health problems, with it causing close to a million deaths each year. Ninety percent of these deaths occur in Sub Saharan Africa and 70% are of children under the age ... 
QCog: a QLearning 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 ... 
Relativistic astrophysical models of perfect and radiating fluids.
(2019)Abstract available in PDF file. 
Relativistic radiating stars with generalised atmospheres.
(2010)In this dissertation we construct radiating models for dense compact stars in relativistic astrophysics. We first utilise the standard Santos (1985) junction condition to model Euclidean stars. By making use of the ... 
Relativistic spherical stars.
(1993)In this thesis we study spherically symmetric spacetimes which are static with a perfect fluid source. The Einstein field equations, in a number of equivalent forms, are derived in detail. The physical properties of a ... 
Relativistic thermodynamics of radiating stars.
(2016)In this research, on the topic of relativistic thermodynamics of radiating stars, the following three case studies are investigated: Gravitational collapse in spacially isotropic coordinates { The nature of a ... 
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. Bioontologies and information visualisation have arisen in recent years as means to assist biologists in making sense of this information. Ontologies can enable the ...
