▼ A commercial unsaturated polyester resin has been used in combination with commercial multiwalled carbon nanotubes (MWNTs) to study the effects of this nanofiller on the electrical properties of the mix in the liquid state, during the cure and in the solid state. The level of addition of the nanotubes ranged from 0.05 to 0.3 wt%. The dispersion of the filler particles in the matrix was carried out combining triple roll milling, horn sonication and high shear mixing. Qualitative optical and electronic microscopy characterisation supports the development of novel techniques for real-time quantitative assessments of dispersion quality. Fitting of shear dependent viscosity, measured between 0.1 and 100 s-1, to Carreau's model has been shown to provide an indicator of the state of nanotube dispersion in the mixture. Additionally, liquid electrical conductivity measurements offer the option of on-line monitoring, providing a promising tool for process optimisation. The formation of an effective conductive network of nanotubes during the cure was investigated by combining impedance spectroscopy measurements and equivalent circuit modelling with two parallel RC circuit in series with each other. This allows in-situ observation of the key phenomenon responsible for the electrical conductivity of the nanocomposite, namely the filler re-aggregation during cure. Optimisation of dispersion and cure parameters results in a nanocomposite showing conductive behaviour in the solid state, achieving DC conductivity of 0.13 S/m at 0.30 wt% loading. The percolation threshold was estimated to occur at 0.026 wt% filler loading. The conductivity achieved is comparable to state-ofthe-art epoxy thermosetting nanocomposites based on use of carbon nanotubes of equivalent quality. Successful laboratory scale trials demonstrated the suitability of the materials in copper electroplating and resistance heating. An industrial scale up trial of a 40 kg batch was carried out, using the dispersion and the monitoring techniques developed in the study.

▼ Archaeological excavation has been widely used in the recovery of human remains and other evidence in the service of legal cases for many years. However, established approaches will in future be subject to closer scrutiny following the announcement by the Law Commission in 2011 that expert evidence will in future be subject to a new reliability-based admissibility test in criminal proceedings. This research evaluates current archaeological excavation methods and recording systems – focusing on those used in the United Kingdom, Ireland, Australasia, and North America – in relation to their use in providing forensic evidence, and their ability to satisfy the admissibility tests introduced by the Law Commission, and other internationally recognised bodies. In order to achieve this aim, two analyses were undertaken. First, attention was directed to understanding the origins, development, underpinning philosophies, and current use of archaeological excavation methods and recording systems in the regions selected for study. A total of 153 archaeological manuals/guidelines were examined from archaeological organisations operating in the United Kingdom, Ireland, Northern Ireland, Scotland, the United States, Canada, Australia, and New Zealand. This research indicated that the Stratigraphic Excavation method and Single Context Recording system, the Demirant Excavation method and Standard Context Recording system, the Quadrant Excavation method and Standard Context Recording system, and the Arbitrary Excavation method and Unit Level Recording system were the approaches most often used to excavate and record graves. Second, the four defined methodological approaches were assessed experimentally, using a grave simulation of known properties to test the excavation, recording, and interpretation of material evidence, the definition of stratigraphic contexts, and understanding of stratigraphic relationships. The grave simulation also provided opportunities to measure archaeologists’ narratives of the grave formation process against the known properties of the grave simulation, and to assess whether archaeological experience had any impact on evidence recovery rates. Fifty repeat excavations were conducted. The results obtained from this experimental study show that the Quadrant Excavation method and Standard Context Recording system was the most consistent, efficient, and reliable archaeological approach to use to excavate and record clandestine burials and to formulate interpretation-based narratives of a grave’s formation sequence. In terms of the impact that archaeological experience had on evidence recovery rates, archaeological experience was found to have little bearing upon the recovery of evidence from the grave simulation. It is suggested that forensic archaeologists use the Quadrant Excavation method and Standard Context Recording system to excavate and record clandestine burials. If this approach is unable to be used, the Demirant Excavation method and Standard Context Recording system, or the Stratigraphic Excavation…

▼ The aim of this study is to increase the depth of data available to swimming coaches in order to allow them to make more informed coaching decisions for their athletes in front crawl swimming. A coach’s job is to assist with various factors of an individual athlete to allow them to perform at an optimum level. The demands of the swimming coach require objective data on the swim performance in order to offer efficient solutions (Burkett and Mellifont, 2008). The main tools available to a coach are their observation and perceptions, however it is known that these used alone can often result in poor judgment. Technological progress has allowed video cameras to become an established technology for swim coaching and more recently when combined with software, for quantitative measurement of changes in technique. This has allowed assessment of swimming technique to be included in the more general discipline of sports performance analysis. Within swimming, coaches tend to observe from the pool edge, limiting vision of technique, but some employ underwater cameras to combat this limitation. Video cameras are a reliable and established technology for the measurement of kinematic parameters in sport, however, accelerometers are increasingly being employed due to their ease of use, performance, and comparatively low cost. Previous accelerometer based studies in swimming have tended to focus on easily observable factors such as stroke count, stroke rate and lap times. To create a coaching focused system, a solution to the problem of synchronising multiple accelerometers was developed using a maxima detection method. Results demonstrated the effectiveness of the method with 52 of 54 recorded data sets showing no time lag error and two tests showing an error of 0.04s. Inter-instrument and instrument-video correlations are all greater than r = .90 (p < .01), with inter-instrument precision (Root Mean Square Error; RMSE) ≈ .1ms−2, demonstrating the efficacy of the technique. To ensure the design was in line with coaches' expectations and with the ASA coaching guidelines, interviews were conducted with four ASA swim coaches. Results from this process identified the factors deemed important: lap time, velocity, stroke count, stroke rate, distance per stroke, body roll angle and the temporal aspects of the phases of the stroke. These factors generally agreed with the swimming literature but extended upon the general accelerometer system literature. Methods to measure these factors were then designed and recorded from swimmers. The data recorded from the multi-channel system was processed using software to extract and calculate temporal maxima and minima from the signal to calculate the factors deemed important to the coach. These factors were compared to video derived data to determine the validity and reliability of the system, all results were valid and reliable. From these validated factors additional factors were calculated, including, distance per stroke and index of coordination and the symmetry of these factors. The system was…

▼ Biodiversity loss is occurring at an unprecedented rate and most of this loss is due to human induced pressure. This loss in biodiversity had led to concerns that the provision of ecosystem services that humans depend upon might be negatively affected. As such much modern conservation science focusses on preserving biodiversity whilst protecting priority ecosystem services. However, there may be spatial and temporal trade-offs between these services and the biodiversity that is considered important. Characterisation of such the relationships between biodiversity and ecosystem services is vital in order to improve management and policies which aim to protect and restore both biodiversity and ecosystem services. The broad aims of the thesis were to explore biodiversity-ecosystem service relationships in (1) ecosystems invaded by non-native plant species and (2) tropical forests affected by human exploitation and disturbance. Specifically this thesis aimed to answer the questions: 1. What effect do non-native plant invasions have on aboveground carbon storage, belowground carbon storage, carbon sequestration, water quality and water provision? 2. How do changes in species richness affect this ecosystem service provision? 3. How do these changes relate to the woodiness and traits of invasive and native dominant species, and the type of ecosystem invaded? 4. What factors drive differences in residual stand damage, biomass loss and species richness change following selective logging? 5. After deforestation how long do carbon stocks and plant biodiversity take to recover in tropical forests? 6. Do carbon and plant biodiversity differ in their recovery rates? 7. Which areas are priorities for restoration of tropical carbon? All chapters in this thesis make use of large datasets that I collated from the literature and other authors in order to draw broad conclusions about trade-offs and relationships between services and biodiversity In the section concentrating on invasive species my results suggest that non-native invasive plants generally increase the storage of carbon, whilst reducing water quality and availability. This may indicate a fundamental trade-off between services where increased biomass of plants results in higher evapotranspiration and thus water loss, while also enhancing the carbon cycle and nitrogen production of microorganisms. In addition my results suggest that aboveground carbon storage increases as species richness is reduced, showing the opposite relationship to that shown in many biodiversity ecosystem functioning experiments. This is the first time any such relationship has been found between community change and ecosystem level impacts in the context of species invasions. However, it seems likely that this relationship depends on the identity and traits of the species, with invasions in open habitats by woody species likely to drive a negative relationship between richness change and biomass change with the opposite true when grassy species invade woodlands. This result presents a trade-off between…

▼ Relay communications has attracted a growing interest in wireless communications with application to various enhanced technologies. This thesis considers a number of issues related to data throughput in various wireless relay network models. Particularly, new implementations of network coding (NC) and space-time coding (STC) techniques are investigated to offer various means of achieving high-throughput relay communications. Firstly, this thesis investigates different practical automatic repeat request (ARQ) retransmission protocols based on NC for two-way wireless relay networks to improve throughput efficiency. Two improved NC-based ARQ schemes are designed based on go-back-N and selective-repeat (SR) protocols. Addressing ARQ issues in multisource multidestination relay networks, a new NC-based ARQ protocol is proposed and two packet-combination algorithms are developed for retransmissions at relay and sources to significantly improve the throughput. In relation to the concept of channel quality indicator (CQI) reporting in two-way relay networks, two new efficient CQI reporting schemes are designed based on NC to improve the system throughput by allowing two terminals to simultaneously estimate the CQI of the distant terminal-relay link without incurring additional overhead. The transmission time for CQI feedback at the relays is reduced by half while the increase in complexity and the loss of performance are shown to be negligible. Furthermore, a low-complexity relay selection scheme is suggested to reduce the relay searching complexity. For the acknowledgment (ACK) process, this thesis proposes a new block ACK scheme based on NC to significantly reduce the ACK overheads and therefore produce an enhanced throughput. The proposed scheme is also shown to improve the reliability of block ACK transmission and reduce the number of data retransmissions for a higher system throughput. Additionally, this thesis presents a new cooperative retransmission scheme based on relay cooperation and NC to considerably reduce the number of retransmission packets and im- prove the reliability of retransmissions for a more power efficient and higher throughput system with non-overlapped retransmissions. Moreover, two relay selection schemes are recommended to determine the optimised number of relays for the retransmission. Finally, with respect to cognitive wireless relay networks (CWRNs), this thesis proposes a new cooperative spectrum sensing (CSS) scheme to improve the spectrum sensing performance and design a new CSS scheme based on NC for three-hop CWRNs to improve system throughput. Furthermore, a new distributed space-time-frequency block code (DSTFBC) is designed for a two- hop nonregenerative CWRN over frequency-selective fading channels. The proposed DSTFBC design achieves higher data rate, spatial diversity gain, and decoupling detection of data blocks at all destination nodes with a low-complexity receiver structure.

▼ Conservation policy and management is undergoing a step-change, moving from focusing conservation resources on individual sites such as protected areas, to include the wider landscape. Landscape-scale initiatives may focus on either managing the entire landscape or they may focus on managing particular sites but attempt to address landscape-scale patterns and processes, such as habitat fragmentation. Whilst there is a vast body of research investigating the impacts of habitat fragmentation on individual species, much less is known about the impacts of habitat fragmentation on ecological processes, for example woody succession. Woody succession is an ecological process which has particular implications for conservation management as it drives ecosystem dynamics which can alter the value of the habitat for species of conservation concern. At the same time there is a move to incorporate ecosystem service protection into conservation policy. Understanding the synergies and trade-offs that exist between biodiversity conservation and ecosystem service provision is therefore an important priority. Few studies have examined the influence of habitat fragmentation on woody succession and, in turn, the impact of woody succession on the value of the habitat for both biodiversity conservation and ecosystem service provision. In addition, there is still very little evidence suggesting to what extent areas managed for biodiversity conservation also provide ecosystem services. There is a need to understand how management approaches aimed at increasing the biodiversity value of conservation areas will impact ecosystem services, particularly at the level of the landscape. This thesis aimed to explore all these themes in the Dorset lowland heathlands, UK. The Dorset lowland heathlands are highly fragmented and a priority habitat for nature conservation because they are rare and threatened and support a characteristic flora and fauna. The main threat to this habitat is now woody succession. Without conservation management, the characteristic dwarf shrub heath undergoes succession and is replaced by scrub and woodland. The objectives of this thesis were to (1) assess the impact of fragmentation on the process of succession on lowland heathlands and quantify lowland heathland vegetation dynamics; (2) determine biodiversity and ecosystem service values of major cover types along a successional gradient on lowland heathlands and assess how trade-offs and synergies between biodiversity and ecosystem service provision vary along this gradient and (3) explore how alternative management approaches aimed at increasing the biodiversity value of lowland heathlands impact ecosystem service provision. Fragmentation was found to promote succession with smaller heaths undergoing succession faster than larger heaths. Trade-offs were found between biodiversity value and ecosystem service provision. Biodiversity value was highest in heath habitats and lowest in woodland. Carbon storage, aesthetic value and timber value were highest in woodland. However,…

▼ In the twenty-first century People with Learning Difficulties (PWLD) still face oppression, discrimination and exclusion from the mainstream of social life. Over recent decades the policy of the United Kingdom’s (UK) government and activist organisations regarding people with learning difficulties has been on enabling inclusion, ensuring rights, providing choice and developing advocacy and independence. People with learning difficulties have been moved out of institutions with the intention to be included and respected as equal members of society. During the same decades that the government and activist organisations have been striving for the inclusion and equality of people with learning difficulties, the use of Information Technology (IT) has reached pervasive levels, to the degree that it is almost impossible for individuals to socially function successfully, unless they have access to it. Unfortunately, most IT is not designed to be usable and accessible to people with learning difficulties and this is a major barrier for their social inclusion. Participatory Design (PD) methodologies which emphasise end-user involvement in the software development process are widely considered the key to system usability and accessibility. However, most researchers and software developers believe that people with learning difficulties are not capable of participating in the process of development as a result of their disabilities. Others, report that they do not know how to work with this specific group of disabled end-users. This discriminatory behaviour is a major reason why IT remains inaccessible to people with learning difficulties. The study described in this thesis combined Evolutionary Prototyping, a software development methodology and Participatory Action Research (PAR), a social science methodology, in order to involve a cohort of four Health Trainers with learning difficulties in the development of a Web 2.0 based system. The aims of the study were to explore how people with learning difficulties could be involved in the development of a software system and if they could use a system developed with their participation. A further aim was to explore how software developers can approach the field of Learning Disability, the issues they will face and how those issues can be overcome. Qualitative data was gathered during fourteen Participatory Action Research meetings, in which the Health Trainers were involved in research, software development and system use. The data was analysed using Thematic Content Analysis facilitated by the use of the NVivo software package. The findings were validated by the participating Health Trainers. The findings suggest that during software development participation, the Health Trainers faced a number of challenges. However, the Health Trainers indicated the type of support they needed from the researcher in order to overcome them. The support required was easy to provide and the Health Trainers managed to engage in the software development process. The study conducted a system use…

▼ Although an efficient form of transhipment, shipping containers accumulated in ports due to global trade imbalances thus not effectively reused and are expensive to dispose of. The aim of this research is to study the energy saving property of a shipping container-structured house (SCH) with high quality external insulation in Glasgow (UK) and Beijing (China) based on its whole life cycle energy performance. The two selected cities represent developed and developing countries which require heating in winter and are representative of the global imbalances in trade. The energy saving property was analysed through comparing the estimated whole life energy between simulated case-study houses under variable scenarios. Apart from demonstration of energy saving in recycled shipping container house in Glasgow and Beijing, this investigation also examines factors affecting the simulation accuracy, factors affecting energy-saving design features for both cities. The analysis of whole life cycle energy was divided into two major parts: embodied energy (EE) and operating energy (OE), and their estimates were conducted separately using different methods. EE was calculated by life energy cycle assessment based on carbon and energy inventories of the key materials, construction methods, recycling process and transportations; OE, mainly in heating energy, is achieved from building simulation (using IES-VE software) in both cities validated by on-site measured data from a case-study house built in Glasgow, UK. The simulation input data include building geometry, local climate conditions (outdoor temperatures, solar radiation, etc.), building heating and ventilation system and usage profiles, external insulation U-values of major components; outputs include dynamic room temperatures and the corresponding energy consumption during the simulation period. Due to various assumptions made in the simulations and calculations, there are uncertainties in the estimates of both EE and OE. Nevertheless, results show that recycling used shipping containers into steel frames for housing could save 90MWh (34%) in embodied energy, compared with using steel frames made from virgin steel. In terms of operational energy, the mean error between measured and simulated indoor temperature is 0.72°C with a standard deviation of 1.48°C, and the difference between simulated and actual energy consumption was about 14%. Compared with statistical data based on the current housing stock and on expected energy consumption according to current building regulations, an SCH insulated to Code for Sustainable Homes level 4 can save 2.9MWh per year (26%) and 3.9MWh per year (34%) OE in Glasgow and Beijing respectively, compared with houses with houses built to 2013 building regulations. The findings can confirm the feasibility of SCH in theory and provide reference to the further study. To supplement, a SAP assessment, an analysis of key impacting factors analysis and further development outlook are included.

▼ The present decades have witnessed major advances in the development and applications of Computational Intelligence Techniques (CITs), which are commonly associated with metabolomics and omics analyses related to diseases diagnosis. This includes, amongst others, research work performed on Niemann-Pick class 1 and 2 diseases (NPC1 and NPC2 respectively), the severest form of which may involve liver dysfunction. Some of the main reasons for the high frequency of CITs use in metabolomics studies are also related to the development of techniques to detect major discriminatory metabolite variables for the purpose of disease diagnosis and progression. Alongside this, is the major demanding requirement to further understand potential metabolic pathways involved in order to improve our understanding of the molecular mechanisms underlying NPC1 disease. NPC1 is a rare neurodegenerative disorder attributable to NPC1 gene function loss, which causes adverse fat storage at the lysosomal levels (Mathieson, 2013; Xu et al., 2010). However, plasma metabolite profiling can provide insights into disease diagnosis and prognosis, while providing a clear ‘picture’ of the underlying metabolites altered during disease processes, including their early stages. Currently, biomarker discovery appears as the most effective solution to employ regarding the monitoring of disease progression (Mathieson, 2013; Ruiz-Rodado et al., 2014). In the present thesis, the intelligent tri-modelling techniques (ITMTs) which are combination of CITs applied to the multivariate (MV) analysis of biofluid datasets is proposed. The ITMTs serves as a combination of the scalar visualisation algorithm (SVA) for data visualisation and high-dimensional data representation into bi or tri-dimensional spaces. The optimum super support vector machine (OSVM) is also employed for the MV classification of metabolic datasets. Moreover, principal component regression (PCR) was also employed for data iv probabilistic classification and regression purposes. This was followed by investigations of correlations between these biomolecular diseases features. Furthermore, the tri-ranking techniques (TRTs) was developed in order to establish a ranking between the NPC1 disease features, in addition to those available for the NPC1 liver dysfunction disease features in a mouse model system to determine their importance in the further development of these diseases. High-resolution proton nuclear magnetic resonance (1H NMR) is used as high-throughput multicomponent analytical technique to generate very large quantities of metabolic data, which hold essential and useful information regarding the metabolites analysed. Prior to the performance of MV metabolomics analysis, a robust data handling technique based on balancing the dataset, feature selection, and stratified cross-validation of datasets is involved. Furthermore, the intelligent task technology fit theory has been proposed here, enabling a swift, consistent and rational model development through threshold settings for model…

▼ The ability to adaptively control manufacturing equipment, both in local and distributed environments, is becoming increasingly more important for many manufacturing companies. One important reason for this is that manufacturing companies are facing increasing levels of changes, variations and uncertainty, caused by both internal and external factors, which can negatively impact their performance. Frequently changing consumer requirements and market demands usually lead to variations in manufacturing quantities, product design and shorter product life-cycles. Variations in manufacturing capability and functionality, such as equipment breakdowns, missing/worn/broken tools and delays, also contribute to a high level of uncertainty. The result is unpredictable manufacturing system performance, with an increased number of unforeseen events occurring in these systems. Events which are difficult for traditional planning and control systems to satisfactorily manage. For manufacturing scenarios such as these, the use of real-time manufacturing information and intelligence is necessary to enable manufacturing activities to be performed according to actual manufacturing conditions and requirements, and not according to a pre-determined process plan. Therefore, there is a need for an event-driven control approach to facilitate adaptive decision-making and dynamic control capabilities. Another reason driving the move for adaptive control of manufacturing equipment is the trend of increasing globalization, which forces manufacturing industry to focus on more cost-effective manufacturing systems and collaboration within global supply chains and manufacturing networks. Cloud Manufacturing is evolving as a new manufacturing paradigm to match this trend, enabling the mutually advantageous sharing of resources, knowledge and information between distributed companies and manufacturing units. One of the crucial objectives for Cloud Manufacturing is the coordinated planning, control and execution of discrete manufacturing operations in collaborative and networked environments. Therefore, there is also a need that such an event-driven control approach supports the control of distributed manufacturing equipment. The aim of this research study is to define and verify a novel and comprehensive method for adaptive control of manufacturing equipment in cloud environments. The presented research follows the Design Science Research methodology. From a review of research literature, problems regarding adaptive manufacturing equipment control have been identified. A control approach, building on a structure of event-driven Manufacturing Feature Function Blocks, supported by an Information Framework, has been formulated. The Function Block structure is constructed to generate real-time control instructions, triggered by events from the manufacturing environment. The Information Framework uses the concept of Ontologies and The Semantic Web to enable description and matching of manufacturing resource capabilities and manufacturing task requests in…

▼ Background: Electronic government (e-government) systems are important across several dimensions, such as the public sector, business sector and the government itself, via the various organs of government. Hence, e-government systems consist of numerous factors, which play various roles in the success of e-government development and adoption. The most important factors from derived from dimensions that impact on the development, implementation and adoption of e-government which are technological, organisational, environmental, and social, also it is intended for and the government decision-makers involved. Therefore, the government of Saudi Arabia is seeking to improve its electronic services (e-services) and so this topic was attractive for the researcher, who in turn, has attempted to make a research contribution to the integration of an e-government system in the context of Saudi Arabia (SA). Aims and Objectives: The aim of this research was to identify insights into the critical factors revealed in a review of the relevant literature. The Literature Review shows that there have been few studies that have considered the critical factors in the development of e-government systems. This thesis is taking into account the experiences of senior government IT staff and the citizens such a system is intended to serve. To present a theoretical understanding of e-government development that based on Technology-Organisation-Environment TOE framework. Consequently, a conceptual framework for the successful development and adoption of e-government was subsequently proposed to improve government services in general and make savings in terms of time, cost and promote the e-services. Methods: Qualitative research data were gathered via 26, in-depth semi-structured interviews from two perspectives: first, from the point of senior IT managers view at four Saudi Ministries and second, from the standpoint of 10 Saudi citizens (five men and five women). Thematic analysis was carried out to identify the critical factors that derived technological, organisational, environmental and social dimensions which influencing e-government development in the Saudi context. Moreover, to highlight the issues to be taken into account when endeavouring to support e-government development in Saudi Arabia’s Ministries. Results: This research makes a significant contribution to understanding e-government development, as it essentially identifies the critical factors that should be targeted by the Saudi government in its efforts to develop e-government. This study therefore brings together these various factors into a single comprehensive conceptual framework, comprising the main elements to be considered when attempting to identify, improve and motivate e-government system development. This is based on the perspectives of senior government IT managers in Saudi Ministries and the intended system users, namely the Saudi public. As a theoretical basis (TOE) Framework was applied and extended to the topic of e-government system development. Conclusion:…

▼ Standard security mechanism such as Access control, Firewall and Encryption only focus on controlling the release of information but no limitations are placed on controlling the propagation of that confidential information. The principle problem of controlling sensitive information confidentiality starts after access is granted. The research described in this thesis belongs to the constructive research field where the constructive refers to knowledge contributions being developed as a new framework, theory, model or algorithm. The methodology of the proposed approach is made up of eight work packages. One addresses the research background and the research project requirements. Six are scientific research work packages. The last work package concentrates on the thesis writing up. There is currently no monitoring mechanism for controlling information flow during runtime that support behaviour configurability and User interaction. Configurability is an important requirement because what is considered to be secure today can be insecure tomorrow. The interaction with users is very important in flexible and reliable security monitoring mechanism because different users may have different security requirements. The interaction with monitoring mechanism enables the user to change program behaviours or modify the way that information flows while the program is executing. One of the motivations for this research is the information flow policy in the hand of the end user. The main objective of this research is to develop a usable security mechanism for controlling information flow within a software application during runtime. Usable security refers to enabling users to manage their systems security without defining elaborate security rules before starting the application. Our aim is to provide usable security that enables users to manage their systems' security without defining elaborate security rules before starting the application. Security will be achieved by an interactive process in which our framework will query the user for security requirements for specific pieces of information that are made available to the software and then continue to enforce these requirements on the application using a novel runtime verification technique for tracing information flow. The main achievement of this research is a usable security mechanism for controlling information flow within a software application during runtime. Security will be achieved by an interactive process to enforce user requirements on the application using runtime verification technique for tracing information flow. The contributions are as following. Runtime Monitoring: The proposed runtime monitoring mechanism ensures that the program execution is contains only legal flows that are defined in the information flow policy or approved by the user. Runtime Management: The behaviour of a program that about to leak confidential information will be altered by the monitor according to the user decision. User interaction control: The achieved user interaction with the…

▼ Information and Communications Technology (ICT) is a concept that represents the convergence of some defining technologies of our time (information technology, computer technology and media technology) and the increasing influences its research and usage have on the society today. With such distinctive features as pervasiveness, ubiquity, malleability, interactivity, augmentation, autonomy and virtualization, ICT research and usage provide an array of ethical and social challenges. However, most contemporary research on ICT ethics concentrates only either on the usage of ICT artefacts or on questions that raise significant theoretical or practical interest such as ICT implants or eHealth. There has been little research on the ethical and social issues associated with research and development. This research draws attention back to the beginning- research and development. It seeks to find out how ethical issues are considered in ICT research being carried out in the UK computing departments/faculties. It investigates the current state of the art with regard to ethics reviews of ICT research through establishing its relevance, availability and effectiveness. The fact that high quality researches (including European projects) in ICT are currently being carried out in so many UK computing departments, which also produce engineers for IT companies, justifies the choice of the UK in this research. Even though a quantitative tool of questionnaire was used as part of the data collection methods, the interpretive and subjective nature of this research find reference in the use of interviews for the main data collection and dialectical hermeneutics for data analysis. Through a dialectical hermeneutic process, the different understandings on availability, relevance and effectiveness of ethics reviews of ICT research emerged. These understandings showed the strengths and weaknesses of the current ethics review procedures in the UK computing departments which provided the basis for relevant recommendations to policy makers.

▼ In the current study, changes in the physics of transitional separated-reattached flow due to changes of a geometry nature and an increase of intensity of free stream turbulence have been investigated numerically using the large eddy simulation approach. Numerical simulations have been carried out using the Open FOAM tool box. Six case studies are selected and divided into two groups of the flows: a low level of intensity of free stream turbulence (< 0.2%) and a high level of intensity of free stream turbulence (3.7%). Each group involves three geometrical shapes: a two-dimensional flat plate, a three-dimensional geometry with an aspect ratio value of 1 and a three-dimensional geometry with an aspect ratio value of 2. To the best of the author’s knowledge, the current study is the first work to explore transitional separated-reattached flow over three-dimensional geometries. In a comparison among the case studies, the separation bubble that formed on the flat plate is longer than that on other geometries, leading to longer temporal and spatial evolution of the transition. In addition, maximum values of the Reynolds stresses in the flat plate are larger than that in other geometries. Furthermore, all case studies show that the transition in the free shear layer is driven by the Kelvin-Helmholtz instability mechanism. Spectral analysis is carried out to cover all the computational domains employing both Fourier transform and wavelet power transform methods. In the current geometries for both incoming flows (with high and low levels of intensity of free stream turbulence), the regular shedding frequencies are in a good agreement with that reported in the literature. In addition, these frequencies are compatible with the Kelvin-Helmholtz instability conditions. Moreover, the spectral analysis indicates that the low frequency of the free shear layer flapping is absent. The evolution of coherent structures is identified by performing flow visualisation techniques. Different evolution processes of transformation of large-scale structures from Kelvin-Helmholtz rolls to hairpin structures are observed depending on the geometry shapes and on the level of intensity of free stream turbulence. The development of the turbulent boundary layer after the reattachment is also examined. For all case studies used here, a dominant observation is that there is no apparent effect of the geometry nature on the delay in the recovery of the reattached turbulent boundary layer.

▼ Projects have evidently become the core activity in most companies and organisations where they are investing significant amount of resources in different types of projects as building new services, process improvement, etc. This research has focused on service sector in attempt to improve project management planning and control activities. The research is concerned with improving the planning and control of software development projects. Existing software development models are analysed and their best practices identified and these have been used to build the proposed model in this research. The research extended the existing planning and control approaches by considering uncertainty in customer requirements, resource flexibility and risks level variability. In considering these issues, the research has adopted lean principles for planning and control software development projects. A novel approach introduced within this research through the integration of simulation modelling techniques with Taguchi analysis to investigate ‗what if‘ project scenarios. Such scenarios reflect the different combinations of the factors affecting project completion time and deliverables. In addition, the research has adopted the concept of Quality Function Deployment (QFD) to develop an automated Operations Project Management Deployment (OPMD) model. The model acts as an iterative manner uses ‗what if‘ scenario performance outputs to identify constraints that may affect the completion of a certain task or phase. Any changes made during the project phases will then automatically update the performance metrics for each software development phases. In addition, optimisation routines have been developed that can be used to provide management response and to react to the different levels of uncertainty. Therefore, this research has looked at providing a comprehensive and visual overview of important project tasks i.e. progress, scheduled work, different resources, deliverables and completion that will make it easier for project members to communicate with each other to reach consensus on goals, status and required changes. Risk is important aspect that has been included in the model as well to avoid failure. The research emphasised on customer involvement, top management involvement as well as team members to be among the operational factors that escalate variability levels 3 and effect project completion time and deliverables. Therefore, commitment from everyone can improve chances of success. Although the role of different project management techniques to implement projects successfully has been widely established in areas such as the planning and control of time, cost and quality; still, the distinction between the project and project management is less than precise and a little was done in investigating different levels of uncertainty and risk levels that may occur during different project phase.

▼ The research presented in this thesis focuses around the question: “can social media tools be used effectively to foster a participatory process that increases environmental citizenship and promote pro-environmental behaviour-change?”. The research aims to understand the role of staff and students in the socio-technical system that influences an institution’s environmental impact. Users need not to be educated, but empowered in order to be able to take decisions that would reduce the environmental impact of their institutions. Therefore a participatory process is suggested as the right tool to nurture environmental citizens, who will be able to take ‘right’ and ‘good’ decisions about their pro-environmental actions. In the last years, social media have emerged as a worldwide phenomenon. But alongside the grand claims of a social media inspired ‘revolution’ lie more nuanced questions around the role of digital tools in ‘every day’ contexts, and whether or not they are facilitating a cultural change or merely adding to the noise of modern life. The thesis contributes to the debate through presenting findings from an action research study at an East Midlands University in which a case study approach was implemented to explore the potentialities offered by participating in decision-making regarding pro-environmental issues in the institutional context, as they are mediated by social media. To generate behaviour-change the two correlated theories of public engagement and environmental citizenship were tested. Findings indicate that behaviour change and enhanced environmental citizenship are achievable through participation using social media, as several interviewees reported a change or a reinforcement of already existing pro-environmental behaviours as a consequence of the campaign. However, the reported changes were minor and it is difficult to advocate that they could noticeably contribute to the requested reduction targets on carbon emission from behaviour-change of the HE sector.

▼ IT systems are attacked using computers and networks to facilitate their crimes and hide their identities, creating new challenges for corporate security investigations. There are two main types of attacker: insiders and outsiders. Insiders are trusted users who have gained authorised access to an organisation's IT resources in order to execute their job responsibilities. However, they deliberately abuse their authorised (i.e. insider) access in order to contravene an organisation’s policies or to commit computer crimes. Outsiders gain insider access to an organisation's IT objects through their ability to bypass security mechanisms without prior knowledge of the insider’s job responsibilities, an advanced method of attacking an organisation’s resources in such a way as to prevent the abnormal behaviour typical of an outsider attack from being detected, and to hide the attacker’s identity. For a number of reasons, corporate security investigators face a major challenge in distinguishing between the two types of attack. Not only is there no definitive model of digital analysis for making such a distinction, but there has to date been no intensive research into methods of doing so. Identification of these differences is attempted by flawed investigative approaches to three aspects: location from which an attack is launched, attack from within the organisation's area of control, and authorised access. The results of such unsound investigations could render organisations subject to legal action and negative publicity. To address the issue of the distinction between insider and outsider attacks, this research improves upon the first academic forensic analysis model, Digital Forensic Research Workshop (DFRWS) [63]. The outcome of this improvement is the creation of a Digital Analysis Model for Distinction between Insider and Outsider Attacks (DAMDIOA), a model that results in an improvement in the analysis investigation process, as well as the process of decision. This improvement is effected by two types of proposed decision: fixed and tailored. The first is based on a predetermined logical condition, the second on the proportion of suspicious activity. The advantage of the latter is that an organisation can adjust its threshold of tolerance for such activity based on its level of concern for the type of attack involved. This research supports the possibility of distinguishing between insider and outsider attacks by running a network simulation which carried out a number of email attack experiments to test DAMDIOA. It found that, when DAMDIOA used predetermined decisions based on legitimate activities, it was able to differentiate the type of attack in seven of the eight experiments conducted. It was the tailored decisions with threshold levels Th=0.2 and 0.3 that conferred the ability to make such distinctions. When the researcher compared legitimate activities, including users’ job responsibilities, with the current methods of distinguishing between insider and outsider attacks,the criterion of authorised access failed…

▼ Despite the high prevalence and global burden of low back pain (LBP), the pathogenesis is poorly understood. Without a better understanding of what structures are involved in the development and chronicity of LBP, the value and efficacy of clinical assessments and physical therapy interventions are limited. Although there is a clear link between the lumbar spine, pelvis and hip extensors during movement in both LBP and healthy subjects, there is limited evidence regarding whether it is passive or active components that are influenced. There is a need for improved prognostic evaluation of patients with LBP, including whether altered hip biomechanics are the result of structural, passive elements, or neuromuscular, active components of movement. Such evaluations will be beneficial for researchers, clinicians and physical therapists. The purpose of the present investigation is initially to demonstrate how a handheld measuring device can be adapted for use in measuring passive hip moments during supine leg raising. Comparisons are then made between subjects with LBP and healthy controls. A validated dynamic biomechanical model is used to calculate passive hip moments at a variety of knee angles, from which a predictive equation is derived, which is specific to each subject. Following a gait analysis protocol, the predictive equation is used to calculate passive hip extensor moments during the hip flexion component of gait. Comparisons are made between passive hip extensor moments, total hip moments, power and work done, in subjects with and without LBP. The present investigation demonstrated the high accuracy of a handheld force transducer for the measurement of passive hip moments. There were no statistically significant differences in passive hip extensor biomechanical properties between subjects with LBP and healthy controls. However, assessment during walking demonstrated significant differences in passive hip extensor moments between subjects with LBP and controls. Further differences were identified in total hip moments, power and work done, despite no differences in gait parameters. It is plausible that the passive and active components of movement interact, although further research is required to determine whether such interactions are consistent and predictable. It was observed that the passive contribution to hip biomechanics during the swing phase of gait is considerable, and should be incorporated into dynamic modelling. Differentiating between passive and active components may be particularly useful for researchers, clinicians and physical therapists, for evaluating which components are influenced by LBP and for assessing the efficacy of component-specific interventions. Future research should expand on this research to include a wider range of LBP patients, with different severity and disability of LBP, to develop a more complete range of data on how passive and active components are influenced and the range of interactions during common movements. Other research should attempt to determine which…

▼ Interval Temporal Logic (ITL) is a flexible notation for the propositional and first-order logical reasoning about periods of time that exist in specifications of hardware and software systems. ITL is different from other temporal logics since it can deal with both sequential and parallel composition and provides powerful and extensible specification and verification methods for reasoning about properties such as safety, time projection and liveness. Most imperative programming constructs can be seen as ITL formula that form the basis of an executable framework called Tempura that is used for the development and testing of ITL specifications.\ ITL has only future operators, but the use of past operators make specifications referring to history more succinct; that is, there are classes of properties that can be expressed by means of much shorter formulas. What is more, statements are easier to express (simplicity) when past operators are included. Moreover, using past operators does not increase the complexity of interval temporal logic regarding the formula size and the simplicity. This thesis introduces past time of interval temporal logic where, instead of future time operators Chop, Chopstar, and Skip, we have past operators past Chop, past Chopstar and past Skip. The syntax and semantics of past time ITL are given together with its axiom and proof system. Furthermore, Security Analysis Toolkit for Agents (SANTA) operators such always-followed-by and the strong version of it has been given history based semantics using past time operators. In order to evaluate past time interval temporal logic, the problem of specification, verification of history based access control policies has been selected. This problem has already been solved using future time of interval temporal logic ITL but the drawback is that policy rules are not succinct and simple. However, the use of past time operators of ITL produces simple and succinct policy rules. The verification technique used to proof the safety property of history based access control policies is adapted for past time ITL to show that past time operators of interval temporal logic can specify and verify a security scenario such as history based access control policy.

▼ Vehicle Ad hoc Networks (VANET) emerged as a subset of the Mobile Ad hoc Network (MANET) application; it is considered to be a substantial approach to the ITS (Intelligent Transportation System). VANETs were introduced to support drivers and improve safety issues and driving comfort, as a step towards constructing a safer, cleaner and more intelligent environment. At the present time vehicles are equipped with a number of sensors and devices, including On Board Units (OBU); this enables vehicles to sense situations affecting other vehicles and manage communications, by exploiting infrastructures such as the Road Side Unit (RSU); creating a Vehicle to Infrastructure (V2I) pathway, or interacting directly with other vehicles creating a Vehicle to Vehicle (V2V) pathway. Owing to the lack of infrastructures and difficulties involved in providing comprehensive coverage for all roads because of the high expense associated with installation, the investigation in this research concentrates on the V2V communication type rather than theV2I communication type. Many challenges have emerged in VANET, encouraging researchers to investigate their research in an attempt to meet these challenges. Routing protocol issues are considered to be a critical dilemma that needs to be tackled in VANET, particularly in a sparse environment, by designing an effcient routing mechanism that impacts on enhancing network performance in terms of disseminating messages to a desireddestination, balancing the generated packet (overhead) on the network and increasing the ratio of packet delivery with a reduced time delay. VANET has some unique characteristics compared to MANET; specifically it includes high mobility and constrained patterns restricted by roads, which lead to generation of a disconnected area occurring continuously between vehicles creating a Delay Tolerant Network (DTN). This is in opposition to applying the multi-hope technique properly to deliver the packet to its desire destination. The aim in this thesis comprises two main contributions. First developing novel routing protocols for a sparse environment in VANET with the context of utilising the mobility feature, with the aid of the equipped devices, such as Global Position System (GPS) and Navigation System (NS). This approach exploits the knowledge of Second Heading Direction (SHD), which represents the knowledge of the next road direction the vehicle is intending to take, in order to increase the packet delivery ratio, and to increase the route stability by decreasing instances of route breakage. This approach comprises two approaches; the first approach was designed for a highway scenario, by selecting the next hop node based on a filtration process, to forward the packet to the desired destination, while the second approach was developed for the intersection and roundabout scenario, in order to deliver the packet to the destination (unknown location). The formalising and specification of the VSHDRP has been performed using the CCA (Calculus of Context-aware Ambient), in order to…

▼ Polymer blended with nanoparticle and ferroelectric materials in two terminal memory devices has potential for electronic memory devices that may offer increased storage capacity and performance. Towards understanding the memory performance of a combination of an organic polymer with a ferroelectric or unpolarised material, this research is concerned with testing the memory programming and capacitance of these materials using two-terminal memory device structures. This research contributes to previous investigation into the internal working mechanisms of polymer memory devices and increases understanding and verifies the principles of these mechanisms through testing previously untested materials in different material compositions. This study makes a novel contribution by testing the electrical bistability of new materials; specifically, nickel oxide, barium titanate and methylammonium lead bromide and considers their properties which include nanoparticles, ferroelectric, perovskite structures and organic-inorganic composition. Due to their material properties which have different implications for internal switching and memory storage. Nanoparticles have a greater band gap between the valence band and conduction band compare to bulk material which is exploited for memory storage and ferroelectric properties and perovskite materials have non-volatile properties suitable for switching mechanisms. Specific attributes of memory function which include charging mechanism, device programming, capacitance and charge retention were tested for different material compositions which included, blend and layered with a PVAc polymer, and as a bulk material with a single crystal structure using MIM memory devices and MIS device structures. The results showed that nickel oxide was the most effective material as a blend with the polymer for memory performance, this was followed by barium titanate, however, methylammonium lead bromide performed poorly with polymer but showed promise as a single crystal structure. The results also showed that an increase in concentration of the tested material in a blend composition resulted in a corresponding increase in memory function, and that blend compositions were much more effective than layered compositions.

▼ In order to meet energy conservation targets and minimize global warming effects, this research is aimed to rise the efficiency of the PV/T system. This research investigates the usage of microencapsulated phase change slurry (MPCM-S) to replace conventional cooling fluids such as water. The phase change materials (PCMs) are encapsulated in a polymer shell forming microencapsulated phase change materials (MPCM) to prevent leakage of the PCMs as well as increasing the thermal conductivity. Mixtures of (5%, 10% and 15%) of microencapsulated phase change materials in water (slurries) were investigated. The use of phase change materials (PCM) improves heat absorption from the PV module due to their high latent heat, consequently increasing thermal output of the system, and electrical output because the PV panel temperature is reduced. The research started with an intensive literature review covering all elements involved, and then the conceptual design of the experimental rig was developed. Theoretical investigations including a steady-state computerized simulation module were developed, this simulation validated depending on a previous research and showed good agreement with results from that published experimental study. This suggested that the computer module could successfully predict the operational performance of the module with satisfactory accuracy. A series of laboratory-based tests were conducted for a wide range of conditions and slurry concentrations. The results were compared to the computer simulation with the same parameters. It was found that the root mean square percentage deviations (RMSPE) between experimental and simulated results were generally under 4%, so considered acceptable for engineering application of PV/T system. A slurry concentration of 10% was found to give the best results. Under operational conditions of 10% MPCM concentration, 3000 Reynolds number and 600W/m2 solar radiation, an experimental test was conducted. The electricity and heat outputs of the system were 108 and 520 W respectively, the associated electrical and thermal efficiency were 14.1% and 68.8%, giving an overall efficiency of 82.9%. The economic analysis was carried out to investigate the feasibility of the MPCM-S based PV/T system in two different climates of Europe. It showed that the system generates higher annual electrical and heat of 488.29 and 2184.93 kWh in a hot climate (using Madrid as an example) than the annual electrical and heat of 323.12 and 1262.1 kWh for colder climate (Stockholm as an example). Consequently, the life cycle cost of MPCM-S based system per kWh were -0.068 and 0.019 GBP for Madrid and Stockholm respectively, and for water-based PV/T system were -0.038 and 0.028 GBP for Madrid and Stockholm respectively. Finally, the environmental effect of the system was investigated by calculating the life cycle CO2 emission reduction of MPCM-S based PV/T system in both climates, they were 11.75 and 6.9 tonnes for Madrid and Stockholm respectively, and for water-based PV/T system were 7 and 3.5 tonnes for…
