On the physical viability of horizonfree collapse.
(2014)The socalled Cosmic Censorship Conjecture has drawn widespread attention amongst astrophysicists and particle physicists. In particular, the endstate of gravitational collapse of a bounded matter distribution is a ... 
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 ... 
On the theory and examples of group extensions.
(1999)The work described in this dissertation was largely motivated by the aim of producing a survey on the theory of group extensions. From the broad scope of the theory of group extensions we single out two aspects to discuss, ... 
On the theory of the frobenius groups.
(2012)The Frobenius group is an example of a split extension. In this dissertation we study and describe the properties and structure of the group. We also describe the properties and structure of the kernel and complement, ... 
Ontology driven multiagent 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 ontologydriven approach for structuring scientific knowledge for predicting treatment adherence behaviour: a case study of tuberculosis in SubSaharan 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 subSaharan 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 ... 
Optimisation of the population Monte Carlo algorithm : application to cosmology.
(2015)In this thesis we study the Population Monte Carlo (PMC) algorithm and utilise simulations to improve the efficiency of the algorithm by optimising the algorithm parameters. We then ap ply these optimisation results to ... 
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 ... 
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 ...
