On dependent risks in insurance and reinsurance portfolios
(HeriotWatt University Actuarial Mathematics and Statistics, 2000) 
On the asymptotics of the heat equation for polygonal domains
(HeriotWatt University Mathematics, 1988) 
On the duration of negative surplus

On the existence and asymptotic behaviour of solutions to a damped nonlinear wave equation
(HeriotWatt University Mathematics, 1979) 
On the spectrum of some gravitational instantons
(HeriotWatt University Mathematical and Computer Sciences, 201511)In this thesis we study Dirac operators on the Euclidean TaubNUT and Schwarzschild spaces coupled to abelian gauge fields, with the aim of computing the zeromodes and bound states. The work is motivated by recently ... 
On valuation of nonhedgeable insurance risks
(HeriotWatt University Mathematical and Computer Sciences, 2007) 
One relator quotients of surface groups
(HeriotWatt University Mathematical and Computer Sciences, 2008) 
Operational research techniques and marketing strategies applied to the aggregate production planning problem
(HeriotWatt University Actuarial Mathematics and Statistics, 1977) 
Optimal Martingale measures and hedging in models driven by Levy processes
(HeriotWatt University Mathematics and Computer Science, 201112)Our research falls into a broad area of pricing and hedging of contingent claims in incomplete markets. In the rst part we introduce the L evy processes as a suitable class of processes for nancial modelling purposes. ... 
Optimisation of some eigenvalue problems.
(HeriotWatt University Mathematical and Computer Sciences, 2007) 
The optimised Schwarz method and the twoLagrange multiplier method for heterogeneous problems
(HeriotWatt University Mathematical and Computer Sciences, 201704)In modern science and engineering there exist many heterogeneous problems, in which the material under consideration has nonuniform properties. For example when considering seepage under a dam, water will flow at vastly ... 
Optimising strategies for learning visually grounded word meanings through interaction
(Mathematical and Computer Sciences, 201808)Language Grounding is a fundamental problem in AI, regarding how symbols in Natural Language (e.g. words and phrases) refer to aspects of the physical environment (e.g. ob jects and attributes). In this thesis, our ... 
An option pricing approach to charging for maturity guarantees given under unitised withprofits policies
(HeriotWatt University Mathematical and Computer Sciences, 2004) 
Parallel algorithms for large sparse systems of differential equations
(HeriotWatt University Mathematics, 1991) 
Parallel evaluation strategies for lazy data structures in Haskell
(HeriotWatt University Mathematical and Computer Sciences, 201605)Conventional parallel programming is complex and error prone. To improve programmer productivity, we need to raise the level of abstraction with a higherlevel programming model that hides many parallel coordination ... 
Partial regularity of local minimisers in the calculus of variations
(HeriotWatt University Mathematical and Computer Science, 201012) 
A partial translation path from MathLang to Isabelle
(HeriotWatt University Mathematical and Computer Science, 201105)This dissertation describes certain developments in computer techniques formanagingmathematical knowledge. Computers currently assistmathematicians in presenting and archiving mathematics, as well as performing calculation ... 
Perceptual dimensions for surface texture retrieval
(HeriotWatt University Mathematical and Computer Sciences, 2008) 
Perceptual texture similarity estimation
(HeriotWatt University Mathematical and Computer Sciences, 201410)This thesis evaluates the ability of computational features to estimate perceptual texture similarity. In the first part of this thesis, we conducted two evaluation experiments on the ability of 51 computational feature ...
