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 ... -
Solution generating algorithms in general relativity.
(2011)We conduct a comprehensive investigative review of solution generating algorithms for the Einstein field equations governing the gravitational behaviour of an isolated neutral static spherical distribution of perfect ... -
Some amenability properties on segal algebras.
(2017)It has been realized that the definition of amenability given by B. E. Johnson in his Classical Memoir of American Mathematical Society in 1972 is too restrictive and does not allow for the development of a rich general ... -
Some aspects of strong gravity effects on the electromagnetic field of a radio pulsar magnetosphere : solving the Maxwell’s equations.
(2019)The general relativistic (GR) effects of a neutron star play a substantial role on the physics at the stellar surface. These neutron stars also host a very strong magnetic field and spin with periods of a few seconds to ... -
Some Mal'cev conditions for varieties of algebras.
(1991)This dissertation deals with the classification of varieties according to their Mal'cev properties. In general the so called Mal'cev-type theorems illustrate an interplay between first order properties of a given class ... -
Southern African Large Telescope observations of Sunyaev-Zel'dovich effect selected clusters from the Atacama Cosmology Telescope.
(2014)We present Southern African Large Telescope (SALT) follow-up observations of seven massive clusters detected by the Atacama Cosmology Telescope (ACT) using the Sunyaev-Zel’dovich effect (SZE). We conducted multi-object ... -
Spatial analysis and efficiency of systematic designs in intercropping experiments.
(2002)In studies involving intercropping plant populations, the main interest is to locate the position of the maximum response or to study the response pattern. Such studies normally require many plant population levels. Thus, ... -
Spatial and spatio-temporal modeling and mapping of self-reported health among individuals between the ages of 15-49 years in South Africa.
(2019)Self-reported health has been commonly used as a measure of individuals health in public health studies. Health presents a complete physical, emotional, and social well-being. It also plays an important role in the ... -
Spatial modelling of fire dynamics in Savanna ecosystems.
(1999)Fire is used in the management of ecosystems worldwide because it is a relatively inexpensive means of manipulating thousands of hectares of vegetation. Deciding how, where and when to apply fire depends primarily on the ... -
Spatio-temporal modelling and mapping of malaria in Angola.
(2017)About half of the world's population is at risk of contracting malaria. The growing number of malaria cases and deaths due to this disease in Africa has become a major challenge to public health care sector. Malaria is ... -
Special topics in probabilistic exchangeability and its applications.
(2017)This thesis evolves around a probabilistic concept called exchangeability and its generalised forms. It is aimed at exploring connections between exchangeability and other sub-areas in mathematical statistics. These ... -
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 ... -
Spherically symmetric charged Einstein-Maxwell solutions.
(1999)In this thesis we study spherically symmetric spacetimes with a perfect fluid source which incorporates charge. We seek explicit solutions to the Einstein- Maxwell system of equations. For nonaccelerating spherically ... -
The statistical analyses of a complex survey of banana pests and diseases in Uganda.
(1999)No abstract available. -
A statistical analysis of dissolving timber pulp properties using linear mixed models.
(2017)The main focus of the study was to understand the behaviour of seven timber genotypes based on seven chemical properties observed during the chemical pulping process with the prime objective of developing methods of grouping ... -
Statistical analysis of the attitudes towards blood donation and transfusion in Mali.
(2016)The demand for blood transfusion in Mali is high, because of the high prevalence of anemia, which is mostly caused by malaria, malnutrition and pregnancy-related complications. In this study a classic KNOWLEDGE, ATTITUDE ...
