This report summarizes the work that has been carried out as part of the FLAVIIR project, a 5 year research program looking at technologies for future unmanned air vehicles. A novel classication of aircraft product defnition is utilised and a framework to estimate the life cycle…
This work presents the development of a three-dimensional lattice material model for wood and its application to timber joints including the potential strengthening benefit of second order effects. A lattice of discrete elements was used to capture the heterogeneity and fracture…
A town planner, faced with the task of designing attractive walking spaces, needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. PEDFLOW is an attempt to create such a tool. It is an agent-based, microscop…
Living in the Information Age, organisations must be able to exploit their data alongside the traditional economic resources of man, machine and money. Accordingly, organisations implement data warehouses to organise and consolidate their data, which creates a decision support s…
Due to the availability of components and the diversity of target applications, mismatches between pre-qualified existing components and the particular reuse context in applications are often inevitable and have been a major hurdle of component reusability and successful composi…
This thesis investigates the potential of aesthetics in the design of Human-Computer Interactions (HCI). In particular, it aims to provide a means by which aesthetics can be applied in photorealistic virtual reality (VR) to create ‘engaging' experiences. Indeed, the author of th…
This thesis describes research conducted into the measure- ment of pedestrian movement. It starts with an examination of current pedestrian detection and tracking systems, looking at several different technologies including image-processing systems. It highlights, as other autho…
This thesis addresses research on the introduction, use and effectiveness of Virtual Learning Environments (VLEs), learning resource supports and experiences of applying these as blended learning supports for modules and programmes in universities. The author's five selected pap…
Computing and software intensive systems are now an inextricable part of modern work, life and entertainment fabric. This consequently has increased our reliance on their dependable operation. While much is known regarding software engineering practices of dependable software sy…
A typical irrigation scheduling problem is one of preparing a schedule to service a group of outlets. These outlets may either be serviced sequentially or simultaneously. This problem has an analogy with the classical earliness/tardiness machine scheduling problems in operations…
In this work, a new thermo-mechanical model is developed by improving on an existing one, applicable to large deep seated landslides and rockslides consisting of a coherent mass sliding on a thin clayey layer. The considered time window is that of catastrophic acceleration, star…
River bank erosion models are a fundamental requirement for understanding the migration and evolution of river meanders, estimating the potential for land-loss and threat to floodplain infrastructure, and predicting the delivery of contaminated floodplain sediments to aquatic ec…
Control mechanisms for optimisation in large distributed systems cannot be constructed based on traditional methods of control because they are typically characterised by distributed information and costly and/or noisy communication. Furthermore, noisy observations and dynamism …
This thesis explores the prediction of rearwards fan noise propagation within the bypass duct and its radiation into the far feld. Two recently developed models: B-induct and GXMunt, are exploited in application to real engine bypass ducts and their performance is evaluated. The…
The Web has changed the face of scientific communication; and the Semantic Web promises new ways of adding value to research material by making it more accessible to automatic discovery, linking, and analysis. Institutional repositories contain a wealth of information which coul…
In broad terms, Recommender Systems use machine learning techniques to process his- torical data about their user’s interests, encoded in user profiles. Once the algorithms used have been trained on user profiles, their output is used to compile a ranked list of all resources av…
Machine failure is often an important source of variability and so it is essential to model breakdowns in manufacturing simulation models accurately. This thesis describes the modelling of machine breakdown durations in simulation models of engine assembly lines. To simplify the…
