Rigidity theory for circle homeomorphisms with singularities
(HeriotWatt University Mathematics, 2002) 
A rigorous approach to combining use case modelling and accident scenarios
(HeriotWatt University Mathematical and Computer Sciences, 201603)Nearly all serious accidents, in the past twenty years, in which software has been involved can be traced to requirements flaws. Accidents related to or involving safetycritical systems often lead to significant damage ... 
Risk capital allocation and risk quantification in insurance companies
(HeriotWatt University Mathematical and Computer Sciences, 201205)The objective of this thesis is to investigate risk capital allocation methods in detail for both nonlife and life insurance business. In nonlife insurance business loss models are generally linear with respect to ... 
Rotation invariant classification of 3D surface texture using photometric stereo
(HeriotWatt University Mathematical and Computer Sciences, 2003) 
Saudi teachers’ and university students’ attitudes toward computing
(HeriotWatt University Mathematics and Computer Sciences, 201604)Computer technology is an important tool that enhances people’s learning, improves their education and influences the development of society. There is considerable research in Western countries studying attitudes towards ... 
Scheduling and resource demand analysis methods in multiprocessor systems
(HeriotWatt University Computer Science, 1977) 
Securing routing protocols in mobile ad hoc networks
(HeriotWatt University Mathematical and Computer Sciences, 201605)A Mobile Ad Hoc Network (MANET) is more prone to security threats than other wired and wireless networks because of the distributed nature of the network. Conventional MANET routing protocols assume that all nodes cooperate ... 
A selfmobile skeleton in the presence of external loads
(HeriotWatt University Mathematical and Computer Sciences, 201710)Multicore clusters provide costeﬀective platforms for running CPUintensive and dataintensive parallel applications. To eﬀectively utilise these platforms, sharing their resources is needed amongst the applications rather ... 
Selforganisation in LTE networks : an investigation
(HeriotWatt University Mathematical and Computer Sciences, 201405)Mobile telecommunications networks based on Long Term Evolution (LTE) technology promise faster throughput to their users. LTE networks are however susceptible to a phenomenon known as intercell interference which can ... 
Semigroup and categorytheoretic approaches to partial symmetry
(HeriotWatt University Mathematical and Computer Sciences, 201307)This thesis is about trying to understand various aspects of partial symmetry using ideas from semigroup and category theory. In Chapter 2 it is shown that the left Rees monoids underlying selfsimilar group actions are ... 
Semilinear elliptic equations on IRn
(HeriotWatt University Mathematics, 1987) 
Sentiment Analysis for microblogging platforms in Arabic
(HeriotWatt University Mathematical and Computer Sciences, 201608)Sentiment Analysis (SA) concerns the automatic extraction and classification of sentiments conveyed in a given text, i.e. labelling a text instance as positive, negative or neutral. SA research has attracted increasing ... 
Skillbased reconfiguration of industrial mobile robots
(HeriotWatt University Mathematical and Computer Sciences, 201205)Caused by a rising mass customisation and the high variety of equipment versions, the exibility of manufacturing systems in car productions has to be increased. In addition to a exible handling of production load ... 
Small population bias and sampling eﬀects in stochastic mortality modelling
(HeriotWatt University Mathematical and Computer Sciences, 201706)Pension schemes are facing more diﬃculties on matching their underlying liabilities with assets, mainly due to faster mortality improvements for their underlying populations, better environments and medical treatments and ... 
Solvability of certain classes of semilinear boundary value problems
(HeriotWatt University Mathematics, 1981) 
Solving key design issues for massively multiplayer online games on peertopeer architectures
(HeriotWatt University Mathematical and Computer Sciences, 200905)Massively Multiplayer Online Games (MMOGs) are increasing in both popularity and scale on the Internet and are predominantly implemented by Client/Server architectures. While such a classical approach to distributed ... 
Some actuarial and statistical investigations into topics on genetics and insurance
(HeriotWatt University Mathematical and Computer Sciences, 2006) 
Some aspects of the dependency of lapse rates on economic conditions
(HeriotWatt University Actuarial Mathematics and Statistics, 2000) 
Some classes of linear maps between C*algebras
(HeriotWatt University Mathematics, 1985) 
Some extensions to the Hopf bifurcation theorem
(HeriotWatt University Mathematics, 1981)
