Data layout types : a typebased approach to automatic data layout transformations for improved SIMD vectorisation
(HeriotWatt University Mathematical and Computer Sciences, 201508)The increasing complexity of modern hardware requires sophisticated programming techniques for programs to run efficiently. At the same time, increased power of modern hardware enables more advanced analyses to be included ... 
Data mining clustering of high dimensional databases with evolutionary algorithms
(HeriotWatt University Mathematical and Computer Sciences, 2005) 
Data mining of manyattribute data : investigating the interaction between feature selection strategy and statistical features of datasets
(HeriotWatt University Mathematical and Computer Sciences, 200906)In many datasets, there is a very large number of attributes (e.g. many thousands). Such datasets can cause many problems for machine learning methods. Various feature selection (FS) strategies have been developed to ... 
Datadriven approaches to content selection for datatotext generation
(HeriotWatt University Mathematical and Computer Sciences, 201505)Datatotext systems are powerful in generating reports from data automatically and thus they simplify the presentation of complex data. Rather than presenting data using visualisation techniques, datatotext systems ... 
Decoupled overlapping grids for modelling transient behaviour of oil wells
(HeriotWatt University Mathematical and Computer Science, 201008)This research presents a new method, the decoupled overlapping grids method, for the numerical modelling of transient pressure and rate properties of oil wells. The method is implemented in two stages: a global stage ... 
The design and performance evaluation of a proactive multipath routing protocol for mobile ad hoc networks
(HeriotWatt University Mathematical and Computer Sciences, 201205)Due to unpredictable network topology changes, routing in Mobile Ad Hoc Networks (MANET) is an important and challenging research area. The routing protocol should detect and maintain a good route(s) between source and ... 
Design,development and testing of iris location algorithms for opthalmoscopy
(HeriotWatt University Mathematical and Computer Sciences, 2005) 
Developing semantic pathway comparison methods for systems biology
(HeriotWatt University Mathematics and Computer Science, 200909)Systems biology is an emerging multidisciplinary field in which the behaviour of complex biological systems is studied by considering the interaction of many cellular and molecular constituents rather than using a ... 
Dialogue enhanced, machine assisted requirements elicitation
(HeriotWatt University Mathematical and Computer Sciences, 201405)The Requirements Elicitation process often involves extracting valuable information from the wealth of extant domain specific, natural language (NL) data to form the requirements for building the future system. It also ... 
Digital image processing and artificial neural networks in screening for age related macular degeneration
(HeriotWatt University Mathematical and Computer Sciences, 2007) 
The distribution of extreme studentized deviates in normal and exponential samples
(HeriotWatt University Actuarial Mathematics and Statistics, 1978) 
The double free boundary value problem of laser welding of thin sheets at medium speeds
(HeriotWatt University Mathematics, 2000) 
Drivers of population cycles in ecological systems
(HeriotWatt University Mathematical and computer sciences, 201204)In this thesis, mathematical models are used to investigate potential drivers of population cycles. Population cycles are a common ecological phenomenon, yet the mechanisms underpinning these oscillations are not always ... 
Ecoevolutionary modelling of infectious disease and host resistance
(HeriotWatt University Mathematical and Computer Sciences, 201502)In this work we take an evolutionary invasion analysis approach to modelling evolution and use it to describe the selection pressures underlying epidemiological traits in natural host populations harboring endemic ... 
The effect of noise in models of spiny dendrites
(HeriotWatt University Mathematical and Computer Sciences, 201005)The dendritic tree provides the surface area for synaptic connections between the 100 billion neurons in the brain. 90% of excitatory synapses are made onto dendritic spines which are constantly changing shape and strength. ... 
Effects of genetic testing on insurance : pedigree analysis and ascertainment adjustment
(HeriotWatt University, 200903)Gas condensate flow, which is very different from the conventional twophase (oil and gas) flow, shows more complicated behaviour around the wellbore owing to condensate buildup and the different velocity effects on ... 
Efficient access to distributed biomedical image data
(HeriotWatt University Mathematical and Computer Sciences, 2005) 
Efficient numerical schemes for porous media flow
(HeriotWatt University Mathematical and Computer Science, 201010)Partial di erential equations (PDEs) are important tools in modeling complex phenomena, and they arise in many physics and engineering applications. Due to the uncertainty in the input data, stochastic partial di erential ... 
Elements of qualitative theory of quasilinear elliptic partial differential equations for mappings valued in compact manifolds
(HeriotWatt University Mathematical and Computer Sciences, 2003) 
Emotions, behaviour and belief regulation in an intelligent guide with attitude
(HeriotWatt University Mathematical and Computer Sciences, 2007)
