On the spatial modelling of mixed and constrained geospatial data
Spatial uncertainty modelling and prediction of a set of regionalized dependent variables from various sample spaces (e.g. continuous and categorical) is a common challenge for geoscience modellers and many geoscience applications such as evaluation of mineral resources, characterization of oil …

Spatial modelling of blue whiting population dynamics in the north-east Atlantic
For this thesis project, a spatial model of the population dynamics of blue whiting, Micromesistius poutassou, in the North-East Atlantic has been developed. Since stock biomass fluctuations recorded in the past decades have raised concerns for the stock sustainability, improving our understanding …

Spatial modelling and analysis of wireless ad-hoc and sensor networks: an energy perspective
This dissertation focuses on modelling and analyzing the spatial characteristics of traffic in these networks so as to extend network lifetime for various application/traffic scenarios. In the first part of the dissertation we consider large-scale sensor networks that systematically sample a …

Spatial modelling of small mammal distributions in relation to parasite transmission in western China
This research investigates the spatial distributions of small mammal species which actas intermediate host vectors for the parasitic tapeworm Echinococcus multilocularis, whichcauses a significant burden of human disease in western China. Small mammal distributionsare modelled in relation to …

The use and development of geographical information systems (GIS) and spatial modelling for educational planning
… on geographical information systems (GIS) and spatial modelling techniques. Although both of these sets of techniques have for many years been applied in other areas, including within local Government, they have yet to permeate to a decision-making level in education planning. Thus the time is …

Approaches to the spatial modelling of cancer incidence and mortality in metropolitan Perth, Western Australia, 1990 -2005
… was used to undertake the analysis on the spatial distribution of cancer rates per 100,000 person-years for Perth Statistical Local Areas during the period 1990-2005. This analysis is based on age-adjusted and age-sex-adjusted rates (non-sex specific cancers only). For lung, colorectal and …

Applying the principles of spatial modelling to the management of biodiversity in the fragmented landscapes of south-western Australia
… actions. This need can be addressed through spatial modelling applications. Unfortunately, throughout much of the world, spatial modelling is forgone, being seen as requiring skills and resources beyond the means of many conservation planners and managers. This thesis seeks to address this …

Development of national extent terrain attributes (TANZ), soil water balance surfaces (SWatBal), and environmental surfaces, and their application for spatial modelling of Pinus radiata productivity across New Zealand
… capital outlay. In this research, a series of spatial surfaces potentially useful in the modelling and mapping of forest productivity across the national extent of New Zealand have been developed. Modelled surfaces include 15 primary and four secondary terrain attributes; 13 shortwave radiation …

Contributions to spatial uncertainty modelling in GIS : small sample data
… is addressed by my research objective: "To model spatial environmental data with .fuzzy uncertainty, and to explore the use of small sample data in spatial modelling predictions, within Geographic Information System (GIS)." The methodologies underlying the theoretical foundations for spatial …

Bayesian networks for spatio-temporal integrated catchment assessment
… was used to facilitate data pre-processing and spatial modelling. Dynamic Bayesian Networks were implemented in the software for time-series modelling.

Regression modelling of cervical cancer and Chlamydia incidence in the context of national screening programmes
… study demonstrated the use of mathematical and spatial modelling to explore the risk factors through various regression models, to explore the relation between socio-economic conditions and disease incidence, and also other techniques including classification analysis, decision models, and …

The dilemma of mind in contemporary Buddhism : some British testimony
… of anticipated futures, but that incautious spatial modelling in linguistic explanation reinforces the notion an internal objective self by treating the mind as a containing entity. From the standpoint of the Buddhist attitude of 'right view', the scientific assertion of the materiality of …

Development of a land use-based spatial water requirements model for the Berg Water Management Area
… to investigate the requirements for the spatial modelling of current and future water demand in the Berg River Water Management Area in the Western Cape of South Africa in order to produce a prototype model from which annual water requirements could be computed and spatially visualised. …

Spatial modeling of soil salinity using remote sensing, GIS, and field data
… information systems (GIS), remote sensing, and spatial modelling techniques. Com and alfalfa crops were selected as indicators of soil salinity during 2001 and 2004 respectively. Five images were acquired from Aster, Ikonos, and Landsat to check the correlation between measured soil salinity and …

Mathematical modelling of drug metabolism : using <em>in silico</em> techniques to investigate the cytochrome P450 enzyme system in hepatic reductase null mice
In silico modelling approaches are useful since they can minimise experimental costs and once set up can be used to replace animal testing for drugs. As such modelling techniques need to be developed to reduce dependence on animals for validation of pharmacological efficacy. The work within this …
