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 well-known 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 multi-type sequences which replaces the independence concept of the objective theory. The aim of this thesis is ... -
A perspective on incomplete data in longitudinal multi-arm clinical trials, with emphasis on pattern-mixture-model 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 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 ... -
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 ... -
Qualitative and structural analysis of video sequences.
(2013-10-17)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 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 ... -
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 ... -
A review of methods for modelling both Gaussian and Non-Gaussian longitudinal data with application.
The study of longitudinal data plays an integral role in medicine, epidemiology, social science, biomedical and health sciences research where repeated measurements are obtained over time for each individual. Generally, ... -
The role of immune-genetic factors in modelling longitudinally measured HIV bio-markers including the handling of missing data.
(2013-12-20)Since the discovery of AIDS among the gay men in 1981 in the United States of America, it has become a major world pandemic with over 40 million individuals infected world wide. According to the Joint United Nations ... -

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 ... -
Shear-free models for relativistic fluids with heat flow and pressure isotropy.
(2014)We model the interior dynamics of a relativistic radiating fuid in a nonstatic spher- ically symmetric spacetime. The matter distribution takes the form of an imperfect fuid with a nonvanishing radially directed heat ... -
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, ... -
Singularity and symmetry analysis of differential sequences.
(2009)We introduce the notion of differential sequences generated by generators of sequences. We discuss the Riccati sequence in terms of symmetry analysis, singularity analysis and identification of the complete symmetry group ...
