▼ A large number of human activities rely on conventional computing devices producing huge quantities of data. These “traditional computers” may eventually fail to deal with such demands. Therefore, there is a need to develop novel computing paradigms, this project aims to fabricate and explore the potential of novel computing devices, based on the space-time dynamics of travelling waves in non-linear media. The designed prototype computing devices are all experimentally implemented in chemical reaction-diffusion media. A light sensitive Belousov-Zhabotinsky (BZ) reaction was used to construct a number of logic gates and arithmetic circuits. A 1-bit half adder was constructed using the collisions of wave fragments within channels in a weakly excitable analogue of the BZ reaction. The excitability of the reaction is controlled by altering the light levels projected onto an immobilised light sensitive catalyst within an open reactor fed with fresh BZ reagents. This approach was extended by projecting a series of interconnected discs with differing connection weight and size. Using this approach an inverter gate, an AND gate, a NAND gate, a NXOR gate, an XOR gate and a diode were created in addition to a compact 1-bit half adder circuit and memory circuits. Using an excitable BZ analogue a 4-bit input, 2-bit output integer square root circuit has been implemented. This utilises the principal of constant speed wave propagation and the annihilation of colliding wave fronts coupled with light controlled valves. The light sensitive BZ reaction was also used as a substrate for exploring the potential of applying co-evolutionary algorithms coupled with memory to control the dynamics in order to solve specific computational tasks. It was shown that learnt solutions from simulation experiments could be directly applied to experimental systems. A “gas free” cyclohexadione analogue of the BZ reaction was encapsulated in 3-D lipid stabilised vesicles. The transfer of excitation between adjacent vesicles could be induced by altering the reaction chemistry. It was also possible to selectively initiate waves using lasers at selected wavelengths. Light activation is important because it will enable initiation in required position of computational schemes. In addition there is a need to study pattern formations in simple inorganic systems in order to gain a better understanding of pattern formation and the control thereof in order to synthesise functional materials and implement computation by utilising the inherent self-assembly mechanisms. Therefore, a simple reaction between aluminium chloride and sodium hydroxide was studied; a phase diagram was constructed of the reaction. A controllable region was found where circular wave, target waves, cardioid like double spiral, simple Voronoi and additively weighted Voronoi diagrams could be constructed. In addition, a group of simple chemical reactions capable of geometric calculations (Generalised and Weighted Voronoi diagrams) are presented. Drops of metal ion solution were placed on either…

▼ Solid-phase micro-extraction (SPME) fibres and automated thermal desorption (ATD) tubes were used with gas chromatography-mass spectrometry (GC-MS), to investigate volatile secretions from the headspace gas of adults and larvae of confused flour beetle Tribolium confusum du Val, saw-toothed grain beetle Oryzaephilus surinamensis (L.), grain weevil Sitophilus granarius (L.), flour mite Acarus siro L. and storage mite Glycyphagus domesticus (De Geer). A number of VOCs were specifically linked with confused flour beetle T. confusum and not observed with the other insect and mite species. For instance, 2-methyl-p-benzoquinone and 2-ethyl-p-benzoquinone were specifically linked to confused flour beetle. However, this study found that benzoquinones were not present in the headspace volatiles of the larvae of confused flour beetle, whereas, 1-pentadecene was detected in adults and larvae of confused flour beetle. The results of the volatile extraction experiments with saw-toothed grain beetles O. surinamensis showed that several volatiles were detected in the adults and larvae of saw-toothed grain beetle but not in the other insect and mite species. Some of these VOCs were detected only in adults, and these were butanoic acid, 1-methylethyl ester and 1,3-octadiene. The others were found in both larvae and adults. These were 2,4-hexadien-1-ol, octane, 3-methylbutanoic acid, 2,5-dimethylpyrazine, 1-octen-3-one and 1-octen-3-ol. The analysis of the headspace from grain weevil S. granarius showed three VOCs which were specifically linked to weevils compared to the other species. These were mequinol, 2-methylpropanoic acid and 2-pentanone. The results showed that the known mite-produced alarm pheromone citral (comprising (Z)-3,7-dimethyl-2,6-octadienal and (E)-3,7-dimethyl-2,6-octadienal) was detected in both mite species flour mite A. siro and storage mite G. domesticus but not in insect species. This study has identified a number of VOCs which may enable the early detection of storage insects and mites in grain stores. Many of the VOCs identified were specific to either mites or one of the insect species studied which could enable specific identification of the cause of infestation.

▼ The concepts of Smart Cities in general and Smart Solutions in particular have emerged during the last decade. A review of the related literature to these concepts has come to the conclusion that 'Smart' is most of the time linked to technological solutions. This is why the Smart City focuses, in a first instance, on the use of technologies for facilitating the management of the different aspects of the city, one of which is energy. The latter is putting organisations under much pressure as on one hand prices are increasing, and on the other, these organisations are compelled to reduce their carbon emissions which can be achieved by decreasing their energy consumption. Hence, there is a great focus on energy management. This thesis focuses on one aspect of the Smart City which is energy management. It deals with the concept of Smart in a specific setting, Local Authorities (LAs), and for a specific aspect which is energy. It addresses the need to identify what Smart can mean in this setting, the change and associated transition it brings to these organisation and how it can improve energy management in order to identify what is meant by Smart Energy Management (SEM). The thesis adopts a mixed methods approach to address the research aim and objectives. The data has been collected in two main phases and using different tools. The first phase consists mainly of interviewing heads of energy management or their representatives from each type of LAs in the UK, and when possible from outside of the country, to explore how the energy management practice is applied in their respective authorities and what additions 'Smart' technologies (like smart meters) are bringing. These data are analysed depending on a set of themes identified in the literature review. The results of this analysis inform the second phase of data collection which consists of an in-depth case analysis of the process of incorporating energy management into a Local Authority and identifies how smart technologies are used for facilitating the application of this practice. Two main data collection instruments are used. The first one is a set of semi-structured interviews with key energy management stakeholders such as heads of energy management, energy managers, building clerks, budget holders and Councillors. The second is a content analysis of corporate documents including the energy management system (EnMS) of the case study Local Authority, energy and metering contracts and periodic energy related reports. The researcher has also sent a questionnaire to the participants in the 1st phase to report and validate the findings with them. The findings from this research support the development of a Smart Energy Management framework for Local Authorities and identify the different factors that can enable its embedding within these organisations. The first group of factors are at the macro level and include legislation & Central Government policy, Central Government financing opportunities, and how the public sector can lead by example. The second group is at the…

▼ 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.

▼ Utility-service provision is a process in which products such as water, electricity, food, gas are transformed by appropriate devices into services satisfying human needs such as nutrition, thermal comfort, and wants such as e.g. entertainment. Utility products required for these processes are usually delivered to households via separate infrastructures, i.e. real-world networks such as electricity grids, water distribution systems or gas distribution networks. Additionally, they can be supplemented sourced locally from natural resources, e.g. electricity can be obtained from sun or wind. The main objectives of the research are to numerically evaluate feasibility of alternative approaches to utility-service provision problems and automatically generate suggestions of such alternative approaches, using knowledge base of present and future technologies and devices. These objectives are achieved via a simulation system implemented in C# and .NET 4.0 that is composed of the following blocks: an interface to define the utility-service provision problem (problem formulation), an interface to define candidate solutions (transformation graphs), a computational engine to analyse the feasibility of transformation graphs, a heuristic search algorithm to generate transformation graphs and a XML database. The core of the proposed approach is a simulation system that carries out a feasibility study of transformation graphs. A transformation graph describes direct and indirect transformations of products into defined services or other products using various devices. The transformation graphs are represented in a form of standard directed graph where devices, product storages and services are nodes and edges represent product and service carriers. In the adapted approach each product has associated storage. The information about products, services and devices is used to create a visual representation of the content of the database - a Mastergraph. It is a directed hypergraph where services and product storages are nodes, while devices are edges spanning between. Since devices usually connect more than two nodes, a standard graph would not suffice to describe utility-service provision problem and therefore a hypergraph was chosen as a more appropriate representation of the system. Two methods for defining transformation graphs are proposed. In the first one the candidate solutions are constructed manually. Additionally, an interface to calculate shortest paths between two products or a product and a service in Mastergraph was developed to simplify the manual process. In the second method, the transformation graphs are automatically generated using heuristic search approach developed for this model. The functionalities of the proposed approach are presented through case studies. A benchmark case study based on the literature is analysed and compared with automatically generated solutions that vary in terms of energy and water delivered by the infrastructure as well as the total cost of supplying and removing products. These case…

▼ In order to explain and determine the attitudes and factors affecting perceptions of students to adopt and use Virtual Learning Environment (VLE) as a tool in complementing and supplementing face-to-face learning, this research combined two theoretical models: Technology Acceptance Model (TAM), one of the more popular acceptance models, and Learning Style Inventory (LSI). The Technology Acceptance Model is one of the models used to study the problem of low adoption or underutilization of technology while learning styles model adopted in order to determines the preferred learning styles for the users of VLE. This study investigates students at Tripoli University, the main University in Libya to understand their perceptions of using VLE with respect to their learning styles. The study used a quantitative descriptive research design method by using a survey as the primary means of data collection. Empirical data were collected from different departments and schools (n=302) to examine the impact of specialisation construct. The study proposed a conceptual model which includes external variables derived from previous research, the core TAM model combined with learning style as an independent variable in order to determine the impact of learning styles on the perception of students towards VLE use. A combination of t tests, ANOVAs, chi-squares, and Pearson’s product-moment correlation coefficients was used to analyse the data by using two techniques: single and multiple regressions. Findings from the quantitative data revealed that, regardless of gender or learning styles impacts, the participants have a strong positive behavioural intention to use VLE tools in their existing learning environment. The results of this study implied that gender and learning styles did not play a significant role in determining perceptions and usage of VLE. However, the other defined independent variables had significant effects on the model and contributed to the explanation of the model except for example, job relevance, complexity factors. The interesting result found in this study was the fact that the specialisation constructs shows that there is a different level of VLE use depending on the student’s specialisation, namely that natural and formal science students showed the most interest in using the new technology. Another interesting outcome found that students’ perceived ease of use demonstrated a more consistent influence compared to usefulness in determining the usage of VLE. This finding is new and is inconsistent with most previous research. Although, the results show that there is no significant impact of learning styles on the research model, the results, however, show learning styles can play a very important role as a moderating factor between beliefs constructs and external variables. The results of the coefficients were not the same for each learning style, which may indicate that different learning styles moderate the relationships between variables involved in the research model (VLEAM). The people with the highest…

▼ 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.

▼ The works of contemporary art using audio, 35mm slide, video, film and computer- based technologies are commonly referred to as time-based media, since they have duration as a dimension. By looking at artworks which are classified in this category, it appears that temporal visual perceptual interpretations are mainly created through the use of the illusion of movement, which is primarily constituted by sequential images. In art holography, the light-based characteristic qualities of this medium compose a kinetic and interactive visual syntax, which are not seen in other imaging technologies, stating its unique creative possibilities. Thus, this study intends to employ holography as an art medium to explore its temporal properties in order to establish a new approach to time-based media art practice. To review the practice and artworks created for this study, the author recognises that the characteristic qualities of a medium is key for the development of its own aesthetic culture. Moreover, the author also identifies that the combination of both the slips form of a hologram and a portable lighting device would be fundamental elements of the suggested new approach. This approach integrates the holographic image replaying process and the Chinese bamboo slips structure to create a scroll form of an artwork presentation, which suggests a viewer to observe with an unrolling activity, section by section. The role of light in this approach is essential as it not only reconstructs the image, but also acts as an intangible guide to indicate the viewing direction, which forms a directional linear temporal expression. This study combines the suggested approach with classical Chinese poetry to create a series of experimental artworks, demonstrating that the literal and figurative meaning of the poem could possibly be elevated through the manipulation of the light source and the scroll from of the image presentation, as the former creates the holographic kinetic expression and the latter reinforces the poetic linearity. This approach could be interpreted as a time-based holographic manifestation, as it unfolds the art to the viewer over time. Furthermore, in terms of the characteristic qualities of holography, the visual expressive techniques and aesthetic features created for this study indicate that such works cannot be recreated without the use of holography. This study reveals that the irreplaceable aesthetic qualities of holography, suggesting that it could expand and diversify the creative potential of time-based media art; and the discussion of this category would not be comprehensive unless taking this medium into consideration. This study establishes a creative possibility of holography and expects the finding to lead to a greater appreciation for future time-based media art practice, thus enriching the temporal artistic expressions. Moreover, as it is practice-based, the process of the research is primarily expressed through a series of holographic artworks, and combined with written format of discussion, which is…

▼ 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.

▼ For as long as people have been able to survive limb threatening injuries prostheses have been created. Modern lower limb prostheses are primarily controlled by adjusting the amount of damping in the knee to bend in a suitable manner for walking and running. Often the choice of walking state or running state has to be controlled manually by pressing a button. While this simple tuning strategy can work for many users it can be limiting and there is the tendency that controlling the leg is not intuitive and the wearer has to learn how to use leg. This thesis examines how this control can be improved using Artificial Intelligence (AI) to allow the system to be tuned for each individual. A wearable gait lab was developed consisting of a number of sensors attached to the limbs of eight volunteers. The signals from the sensors were analysed and features were extracted from them which were then passed through 2 separate Artificial Neural Networks (ANN). One network attempted to classify whether the wearer was standing still, walking or running. The other network attempted to estimate the wearer's movement speed. A Genetic Algorithm (GA) was used to tune the ANNs parameters for each individual. The results showed that each individual needed different parameters to tune the features presented to the ANN. It was also found that different features were needed for each of the two problems presented to the ANN. Two new features are presented which identify the movement states of standing, walking and running and the movement speed of the volunteer. The results suggest that the control of the prosthetic limb can be improved.

▼ In an attempt to establish more efficient and transparent governmental services, manual systems of government across the globe are being transferred to e-government systems, including the Kingdom of Saudi Arabia (KSA). However, this transformation, and especially ensuring user acceptance of e-government, poses a number of challenges. Against this backdrop, the current work examines issues that are related to information trust, professional ethics, and the risks incurred in embracing an e-government. This was carried out based on three Saudi Arabian organisations namely the Ministry of Interior; the Ministry of Communication and Information Technology; and King Abdul-Aziz City for Science and Technology. Qualitative methods was adopted for both data collection and analysis based on semi-structured interviews and questionnaires. The data were analysed using thematic analysis to establish perceptions and behavioural patterns of e-government systems among both government officials and general users. A technological gap was identified as the core impediment to widespread implementation and user acceptance of e-government in KSA. It was established that governmental success in ensuring the system is resilient against data loss and hacking, and habitual adoption of checking mechanisms, can lead towards improved implementation of e-government, along with its utilisation throughout KSA. This research contributes a research model, informed by institutional theory, of factors affecting the adoption of e-government from both employees and citizens’ perspectives (as evident within KSA). It responds to calls from other Information Systems researchers to study e-government by conducting an in-depth field investigation using qualitative research. In doing so, it addresses issues related to information trust, professional ethics and risk in e-government implementation.

▼ Community media is less well funded, supported and researched than other forms of media, and yet it holds considerable potential as a transformative experience and as an agent for social change. This thesis explores how the process of participation in community media represents an opportunity for reinvigorated democratic and civic conversations about issues of concern to local communities, particularly in relation to the idea of participation and advocacy. This thesis contests mainstream media studies discourse by asserting that it is in paying attention to the lived experience and the accomplishments of people acting in lifeworlds and intimate social networks, rather than simply looking at texts, legal frameworks and institutions, that it is possible to develop a wider understanding of changes in media and digital media production situations, particularly those defined by notions of participation, activism and agency. The study uses an ethnographically-informed mixed-methods design that incorporates participant observation, interviews and reflexive engagement. It is founded on principles of pragmatically in-formed symbolic interactionism, which suggest that it is possible to attend to the unfolding of human actions and understandings as they are accomplished in the collective expression of community life that are shaped by neutral social processes. This thesis therefore contributes to an underdeveloped area of media analysis, signalling opportunities for further study and evaluation of the developments of community media at a time of significant change and social reorientation.

▼ In recent years, there has been a movement in arts and one of the interests was in the uncanny where it was relating to surrealism. Previous artwork has addressed the Freudian uncanny concept as an unfamiliar, frightened emotion that is negatively disturbing. However, the concept of Nicholas Royal that uncanny can be strangely beautiful has opened up a new sight that been followed in this thesis. The artwork and art exhibition on fine art are mostly descriptive on creating acceptable uncanny artwork with a sense of beauty. To address the uncanny differently than what used to be and shed the light into the site of beauty to respond, a practice-based research has been carried out to highlight that uncanny can be perceived as beautiful in art. The fundamental aim of this research is to characterise a clear understanding of uncanny beauty. The three research exhibitions of this work were targeting the understanding of what I call" beautiful uncanny", as there is a reflective process in the relationship between the imagination of beauty with the uncanny feelings in a body of visual work. In the light of previous literature, related artwork and my understanding, a creation of human figures, hybrid with insects, through sculpture, based on photography have supported the theory of uncanny as being beautiful with further validation based on testing the responses of the viewers who attend the research exhibitions. The qualitative research has been used in this study to conduct the data of the questionnaire and semi-structured interview. The findings of the study have revealed that the importance of classifying uncanny as being beautiful without any rejection is to establish an artwork that increases attraction and curiosity toward knowledge through understanding the actual feelings of the presented artwork. Therefore, that has proposed an original contribution to the knowledge of the perspective of "The Beautiful Uncanny".

▼ This study investigates the role of new media technologies in the development of African literature. It examines the different ways that these new technologies such as the Internet and mobile phones have revolutionised the way Africans write and read literary works on the continent. African literature refers to literary works written mostly by Africans in any language. Over the last decade, new African writers have created a stir in the arenas of creative writing. Uses and gratification as well as diffusion of innovation theories were adopted as the theoretical framework for this study. A total of 30 African writers and 300 readers completed a survey questionnaire designed to elicit responses on how new media has influenced African literature. Some of the writers interviewed have distinguished themselves in their fields, their works have appeared alongside works of other international writers. The readers were chosen from a popular literary society. The results of the study indicate that the Internet has a big impact on reception of African literature, creating endless opportunities, easy accessibility, promotion of work and networking with peers and literary community. The findings also show that social media also increases networking opportunities and provides a platform where readers access, share and discuss African literature. Mobile phones also play a significant and functional role in the reception and promotion of African literature. Overall, these findings suggest that new media technologies have created opportunities for African literature to be appreciated globally, and have enabled readers to access, share and discuss new works.

▼ 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…

▼ Individual differences within populations in a range of phenotypic traits are hypothesised to have important ecological and evolutionary implications. Variation in individual growth rates that result in corresponding variations in body sizes, including size dimorphism, is a particularly widespread feature of many animal populations. The increasing characterisation of consistent individual behavioural variations, unrelated to age or sex, is equally considered to have important fitness consequences. Our understanding of behavioural causes of size dimorphism remains weak, and few studies have investigated the relationship between individual behavioural consistency and growth variations in size dimorphic populations. The overall aim of this thesis is to identify the behavioural drivers that underpin observed growth variations and result in size dimorphism by using pike (Esox lucius) as a model species. The results show that early life growth is an important driver of sexual size dimorphism in this species. A subsequent focus on the juvenile life stages revealed that individual differences in movement and dispersal tendencies were related to growth and body size in wild pike. The findings indicate that intraspecific interactions such as size-dependent interference competition during the first year of life plays a key role in maintaining intraspecific size variation and size dimorphism in the wild population. Experimental work revealed the occurrence of a behavioural syndrome, where the rank order differences in the foraging behaviour between individuals were maintained across time and risk situation. This suggests that individual competitive ability is underpinned by a variation in boldness to forage under risk. The importance of a heterogeneous environment and presence of intraspecific competition pressure for driving habitat and resource segregation, and subsequently sexual size dimorphism, is discussed.

▼ Open-air rock-art forms one of the most widely distributed categories of prehistoric material culture with examples recognized across the Old and New Worlds. It is also one of the most threatened features of human heritage and is susceptible to accelerated decay as a result of anthropogenic and natural processes. Much attention has previously been given to the impact of identifiably human activities and their mitigation, but the aim of this research is to redress the balance and focus on understanding the short-, medium-, and long-term impacts of natural processes. The main objectives of research are to identify open-air rock-art natural degradation causes, create a suitable method to assess the state of conservation of any given engraved outcrop of the Côa Valley rock-art complex and develop a urgency scale for conservation interventions. The urgency scale will be established by thoroughly examining a sample of the most – in terms of conservation – representative engraved outcrops. Since more than one thousand outcrops with rock-art still subsist today, it would be impossible to examine them all. Therefore, a sample comprising outcrops that possess most, if not all, of the variables that might affect stability and conservation state will be chosen. Some of the issues to consider are weathering and erosion of outcrops, or slope gradient and aspect of the hills where these are located. Such phenomena as biological colonization, rainwater percolation or chemical exchanges at surface level will also be analyzed. The expected end result of research is the creation of a method to determine the condition of outcrops and to identify methodically those in most urgent need of conservation. As a result, informed conservation action plans can be systematically tailored to suit specific natural conditions. Moreover, conservation interventions can be prioritized within a total universe of 1000 outcrops with rock-art.

▼ 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…

▼ 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,…

▼ The potential impacts of climate change on many species worldwide remains unknown, especially in those tropical regions that are centers of endemism and are highly biodiverse. This thesis provides an insight into the extinction risk of selected tree species using different species distribution modelling techniques and reviewing the current conservation status on montane forest in the Tropical Andes. Starting with a global analysis, the potential impacts of climate change on montane ecoregions is investigated, by identifying those that are more vulnerable to the expected changes in temperature and precipitation, from global predictions under different climate change scenarios. It then gives an insight on the current and potential threats to biodiversity in the Andean region, including the identification of those that are most likely to be responsible for increasing the extinction risk of the species. With the use of the IUCN Red List Categories and Criteria, selected tree species were assessed to identify their extinction risk. Information on the species’ current distribution was collated and used to estimate their potential distribution under climate change, by using different modelling techniques. These results were used to reassess the species using the IUCN Red List and establish the changes in Red List Category. Lastly, it provides a discussion that integrates all the results obtained throughout the thesis, to explore the implications for conservation, in order to highlight the overriding importance of including threatened tree species to target conservation efforts in the region, while considering the uncertainties that surround predictions under climate change scenarios, modelling techniques and the use of the IUCN Red List.

▼ New testing procedures used as an aid for law enforcement are subject to intensive scrutiny in the courts. In recent years in workplace drug testing there has been a shift away from using traditional specimens (i.e urine) for drug testing and monitoring and a move to employing less invasive testing using oral fluid. Whilst it is now widely accepted that drugs can be detected in oral fluid and devices are now available to facilitate analysis of drugs in this matrix, our understanding of the behaviour of drugs in the mouth and oral secretions is far from complete. Since the introduction of oral fluid drug testing in the late 1990’s it has been observed that some drugs appear to be present at higher than expected concentrations, often at concentrations that would be fatal if they were in blood. Clearly some extra process is occurring in addition to drugs entering the oral fluid by simple blood and saliva partitioning. Little is really known about the physiology of drugs in the mouth and limited understanding of drug elimination via the mouth poses a problem to forensic toxicologists with the interpretation of analytical results in relation to an individual’s drug use or the possible effects that the drug may be exhibiting on that individual. The work described in this thesis is aimed at increasing our understanding of the factors and processes concerning the deposition, secretion and detection of drugs in oral fluid and enhancing our ability to interpret the results of analysis in this matrix. The objective of this study was to explore how high drug concentrations can be deposited in the mouth tissues and oral fluid together with other factors that may influence drug detection in order to assist with the interpretation of testing results. To test the hypothesis that drug depots form within the mouth, preliminary screening methods in combination with confirmatory techniques such as GC-MS and LCMS/ MS were employed. The development of an immunohistochemical method was successfully demonstrated for the detection and visualisation of cocaine and opiates (heroin and morphine) in porcine and mouse tissue. The work undertaken in this thesis showed that elevated drug concentrations can be observed when drugs are consumed via oral administration either in form of an oral solution or smoking. Immunohistochemical analysis in combination with confirmatory techniques demonstrated that drugs such as cocaine and opioids can bind to oral tissue and be subsequently released over time, therefore has the potential to contribute to the drug concentration in oral fluid. Although this is not an issue under legislation that forbids the presence of drugs or as a check for drug compliance or abstinence, it must be considered in relation to the interpretation of results in more complex forensic cases.

▼ 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…

▼ 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…

▼ Disagreement amongst users in a social network might occur when some of them have different opinion or preferences towards certain items (e.g. topics). Some of the users in the social network might have dynamic preferences due to certain situations. With these differences in opinion amongst the users, some of the users might decide to become either less-active or inactive in providing their opinions on items for recommendation processes to be possible or effective. The current state of the users will lead to a cold-start problem where the recommender system will be unable to find accurate preference information of the users for a recommendation of new items to be provided to them. It will also be difficult to identify these inactive or less-active users within a group for the recommendation of items to be done effectively. Attempts have been made by several researchers to reduce the cold-start problem using singular value decomposition (SVD) algorithm, but the disagreement problem amongst users will still occur due to the dynamic preferences of the users towards items. It was hypothesized in this thesis that an influence based preference modelling could resolve the disagreement problem. It is possible to encourage less-active or inactive users to become active only if they have been identified with a group of their trustworthy neighbours. A suitable clustering technique that does not require pre-specified parameters (e.g. the number of clusters or the number of cluster members) was needed to accurately identify trustworthy users with groups (i.e. clusters) and also identify exemplars (i.e. Cluster representatives) from each group. Several existing clustering techniques such as Highly connected subgraphs (HCS), Markov clustering and Affinity Propagation (AP) clustering were explored in this thesis to check if they have the capabilities to achieve these required outputs. The suitable clustering technique amongst these techniques that is able to identify exemplars in each cluster could be validated using pattern information of past social activities, estimated trust values or familiarity values. The proposed method for estimating these values was based on psychological theories such as the theory of interpersonal behaviour (TIB) and rational choice theory as it was necessary to predict the trustworthiness behaviour of social users. It will also be revealed that users with high trust values (i.e. Trustworthy users) are not necessarily exemplars of various clusters, but they are more likely to encourage less active users in accepting recommended items preferred by the exemplar of their respective cluster.

▼ 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:…

▼ This thesis investigated the applicability of unique combinations of multimodal metaphors to deliver different types of feedback. The thesis evaluates the effect of these combinations on the usability of electronic feedback interfaces and on the users' engagement to learning. The empirical research described in this thesis consists of three experimental phases. In the first phase, an initial experiment was carried out with 40 users to explore and compare the usability and users' engagement of facially animated expressive avatars with text and natural recorded speech, and text with graphics metaphors. The second experimental phase involved an experiment conducted with 36 users to investigate user perception of feedback communicated using avatar with facial expressions and body gestures, and voice expressions of synthesised speech. This experiment also aimed at evaluating the role that an avatar could play as virtual tutor in e-feedback interfaces by comparing the usability and engagement of users using three different modes of interaction: video with tutor that presented information with facial expressions, synthesised spoken messages supported with text, and avatars with facial expressions and body gestures. The third experimental phase, introduced and investigated a novel approach to communicate e-feedback that was based on the results of the previous experiments. This approach involved speaking avatars to deliver feedback with the aid of earcons, auditory icons, facial expressions and body gestures. The results demonstrated the usefulness and applicability of the tested metaphors to enhance e-feedback usability and to enable users to attain a better engagement with the feedback. A set of empirically derived guidelines for the design and use of these metaphors to communicate e-feedback are also introduced and discussed.

▼ 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.

▼ 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…

▼ 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…
