A theoretical investigation of an averaged-structure eddy viscosity model applied to turbulent shear flows
The project is concerned with the study of a new mathematical model in which the structure of turbulence is described by averaging the effects of the eddies of various scales over the whole volume of flow. The model assumes that the turbulent stresses can be presented in a way analogous to the …

Some aspects of fitting multinomial models in a GLM framework
This thesis discusses how an iteratively re - weighted least squares algorithm can be used to fit a multinomial regression model, with logit link function or own link functions, with any number of explanatory variables. The responses of each individual can be aggregated and the data can then be …

Choosing more mathematics: an exploration of participation and learner identities in the further mathematics network
… their choices of whether or not to study further mathematics within an after-school widening participation programme, the Further Mathematics Network (FMNetwork). I seek to conceptualise how patterns of participation in advanced mathematics arise not only from unequal school provision but in the …

Geometric and homological methods in group theory: constructing small group resolutions
Given two groups K and H for which we have the free crossed resolutions, B* --> K and C* --> H respectively. Our aim is to construct a free crossed resolution, A* --> G, by way of induction on the degree n, for any semidirect product G = K x H. First we show how to find a set Z1 of generators for …

The asymptotic and oscillatory behaviour of difference and differential equations
This thesis deals with the asymptotic and oscillatory behaviour of the solutions of certain differential and difference equations. It mainly consists of three parts. The first part is to study the asymptotic behaviour of certain differential equations. The second part is to look for oscillatory …

Simulation modelling of spatial problems
The thesis presents a simulation modelling strategy for spatial problems which uses a data structure based on spatial relationships. Using this network based approach, two domain specific data-driven models are developed in which the movement of people is modelled as a quasi-continuous process. The …

A class of functional differential equations of mixed type
This thesis is concerned with a class of linear functional differential equations of mixed type.

Some applications of generalised linear models
This thesis is concerned with some extensions to and applications of generalised linear models and their implementation in a statistical package. The principal extension considered is the inclusion of extra parameters in the link function of the model in order to create a family of parametric link …

Tests for uncharacteristic changes in time series data and the effects of outliers on forecasts
The thesis deals with some of the anomalies,that affect the predictive performance of univariate time series. This project should help to improve the forecasts made and should also assist those engaged in time series forecasting in real life situations in industry,government and elsewhere. The …

Minimax in the theory of operators on Hilbert spaces and Clarkson-McCarthy estimates for lq (Sp) spaces of operators in the Schatten ideals
The main results in this thesis are the minimax theorems for operators in Schatten ideals of compact operators acting on separable Hilbert spaces, generalized Clarkson-McCarthy inequalities for vector lq-spaces lq (Sp) of operators from Schatten ideals Sp, inequalities for partitioned operators and …

Generalized structural time series model
A new class of univariate time series models is developed, the Generalized Structural (GEST) time series model. The GEST model extends Gaussian structural time series models by allowing the distribution of the dependent variable to come from any parametric distribution, including highly skew and=or …

Migrants becoming mathematics teachers : personal resources and professional capitals
… (PGCE) course in London to become teachers of mathematics in English schools. It draws upon Bourdieu’s theory of habitus and field to discuss how these student teachers adapt their capitals, as described in migration studies by Erel (2010) and Nowicka (2015) and how, during initial teacher …

A study into identity formation : troubling stories of adults taming mathematics
… negotiate their relationship with schoolroom mathematics through discourses akin to being ‘more’ or ‘less’ able to ‘do’ and ‘be’ mathematical. It argues that mathematical identities are politically and socially constructed, and that available forms of knowledge inscribe particular mathematical …

General methods for analyzing bounded proportion data
This thesis introduces two general classes of models for analyzing proportion response variable when the response variable Y can take values between zero and one, inclusive of zero and/or one. The models are inflated GAMLSS model and generalized Tobit GAMLSS model. The inflated GAMLSS model extends …

Mature non-specialist undergraduate students and the challenges they face in learning mathematics
… year undergraduate university students studying mathematics as an ancillary subject. The challenges faced by such students taking mathematics as a subsidiary subject within their main degree have not been adequately addressed in the literature: this study seeks to address this gap. The research …
