Lessons learnt from the construction industry have proved that knowledge management (KM) can enhance construction projects successfully. The existing KM models and tools may have some problems, which cannot be used efficiently and effectively. This research aims to develop a new…
This thesis describes the investigation and development of damage modelling techniques for woven long glass fibre reinforced polypropylene matrix composites. The objective of the work was to develop and validate predictive models for the intralaminar damage behaviour of these ma…
This research project focused on the treatment of safety risks in railways. Existing methodologies for assessment and management of the safety risk on railways are mostly empirical and have been developed out of a need to satisfy the regulatory requirements and in response to a …
Design techniques used for two-port coupled resonator circuits are extended in this thesis to multi-port coupled resonator circuits. Three-port coupled resonator power dividers and diplexers are demonstrated in particular. The design approach is based on coupling matrix optimiza…
A widely used analytical, image charge, model of the SNMM was analysed for the first time in terms of its ability to predict the response of the SNMM to both bulk and thin film dielectrics. For the first time it was shown that the uncertainty in fitting to the model reduces from…
Higher education institutions (HEIs) in England occupy approximately 25 million m2 of gross space. Many of the buildings in these estates were constructed when thermal standards were far lower than those specified today. Estate managers now need to consider how to manage existin…
Urban demand has increased the need to redevelop contaminated land. New legislation for land management has actively discouraged previously acceptable dig and dump practices. This has encouraged in-situ remediation approaches, for which stabilisation / solidification (S/S) is pa…
The discovery of otoacoustic emissions (OAE) has advanced our understanding of cochlear mechanics and the efferent auditory system. OAE are sounds generated within normal cochlea either spontaneously or in response to stimulation. The ability to measure OAE non-invasively, objec…
The research demonstrates that Three-Dimensional Variable-Density Groundwater Flow models such as the SEAWAT model can be effectively used for design of subsurface drainage systems for controlling salt concentration in the root zone on salt affected irrigated land. The SEAWAT mo…
Source analysis of the Auditory Evoked Potential (AEP) has been used before to evaluate the maturation of the auditory system in both adult and children; in the same way, this technique could be applied to ongoing EEG recordings, in response to acoustic specific frequency stimul…
It is well established that anodes for solid oxide fuel cells (SOFCs) can be manufactured by processes involving final sintering. This research investigated a novel alternative method which relies on the electroless co-deposition of yttria-stabilised zirconia (YSZ) or ceria-stab…
Abstract Noise generated by high-lift devices such as slats on a wing is a major contributor to the overall airframe noise during the landing approach of a commercial aircraft. In this work the concept of attenuating slat noise using absorptive acoustic lin- ers in the slat/main…
The integral bridge concept eliminates problems associated with expansion joints and bearings used on conventional bridges. However, integral structures are not free from problems, and of particular concern is the magnitude of lateral soil stress which acts on the abutments. The…
The use of satellite altimeter data for spatial mapping of the wave resource is examined. A new algorithm for estimating wave period from altimeter data is developed and validated, which enables estimates of wave energy converter (WEC) power to be derived. Maps of the long-term …
The electricity industry was designed more than 50 years ago when the load and generation was less, now we are in the information age with a digital society where the demand is very high, this has forced the electricity infrastructure to its limits which was not designed for, in…
This study examines the relationship between the economic benefit of specific air services and the perceived cost of the carbon dioxide emissions from the aircraft operating the services. Initially a review is made of the basic evidence of climate change and air transport's cont…
The research was aimed at the development of an optimal road fund allocation model for road maintenance to three road agencies in Ghana. The objective was to compare a novel model by multicriteria analysis (MCA) with deterministic outcome and a model based on preferential analys…
Electromagnetic signal velocity measurements are common in soil disciplines, often involving Time-Domain Reflectometry. However, Time-Domain Reflectometry measurements are of limited use where velocity is frequency dependent, such as in finegrained soils. Therefore, Quarter-Wave…
Many studies propose new advanced railway subsystems, such as Driver Advisory System (DAS), Automatic Door Operation (ADO) and Traffic Management System (TMS), designed to improve the overall performance of current railway systems. Real time train positioning information is one …
