#### 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 ...

#### Developing an integrated decision support system for an oil refinery.

(1998)

This thesis considers the problem of residue upgrading operations in an oil
refinery. Visbreaking is a residue-upgrading process that improves profitability
of a refinery. The economics of converting the heavy residue ...

#### Double-diffusive convection flow in porous media with cross-diffusion.

(2011)

In this thesis we study double-diffusive convection and cross-diffusion effects in flow
through porous media. Fluid flows in various flow geometries are investigated and
the governing equations are solved analytically ...

#### 2-generations pf the sporadic simple groups.

(1997)

A group G is said to be 2-generated if G = (x, y), for some non-trivial elements x, y E G. In this thesis we investigate three special types of 2-generations of the sporadic simple groups. A group G is a (l, rn, n )-generated ...

#### Asymptotic analysis of singularly perturbed dynamical systems.

(2011)

According to the needs, real systems can be modeled at various level of resolution.
It can be detailed interactions at the individual level (or at microscopic level) or a
sample of the system (or at mesoscopic level) and ...

#### Transport on network structures.

(2013)

This thesis is dedicated to the study of flows on a network. In the first part of the work, we
describe notation and give the necessary results from graph theory and operator theory that will
be used in the rest of ...

#### Initial conditions of the universe : signatures in the cosmic microwave background and baryon acoustic oscillations.

(2012)

In this thesis, we investigate the signatures of isocurvature initial conditions in the cosmic microwave
background (CMB) through the temperature and polarization anisotropies, and in the
large-scale structure distribution ...

#### Applications of embedding theory in higher dimensional general relativity.

(2012)

The study of embeddings is applicable and signicant to higher dimensional theories of
our universe, high-energy physics and classical general relativity. In this thesis we investigate
local and global isometric ...

#### Age structured models of mathematical epidemiology.

(2013)

We consider a mathematical model which describes the dynamics for the spread of a directly
transmitted disease in an isolated population with age structure, in an invariant habitat, where
all ...

#### 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 ...
