▼ The ability to detect and adapt to changing conditions
and circumstances is a requirement of life at both the organismal
and cellular levels. Inside the cell, rapid and fine-tuned
responses to environmental cues can be achieved through dynamic
post-translational modifications (PTMs) of proteins. Significant
insights into the activity and dependencies of signaling pathways
can therefore be gleaned from global surveys of PTM events, and in
particular protein phosphorylation, as it is absolutely essential
in the signaling cascades mediating the downstream functions of
receptor tyrosine kinase systems. In
T cells, coordinated
phosphorylation of tyrosine residues is critical for transmission
of signals from the activated
T cell receptor. Investigations into
the dynamic phosphoproteome of
T cells have been greatly assisted
by advances in mass spectrometry, which allows for the
identification and quantitation of thousands of PTMs simultaneously
without a requirement for site-specific antibodies. However,
despite the increasing resolution and decreasing cost of mass
spectrometry assays, the complex network of phosphorylation events
governing
T cell activation has been only incompletely
characterized. In particular, while it is now appreciated that
numerous feedback pathways within the
T cell phosphoproteome work
together to regulate the initiation of immune responses, when and
where feedback loops occur in the pathway is poorly understood. To
better understand the role that critical
T cell signaling
components play in feedback regulation of the
T cell receptor
pathway, we conducted a phosphoproteomic study into the role of
Phospholipase C-γ1 in mediating the activation state of the
receptor-proximal signaling machinery. Additionally, we
investigated the application of optimized chromatography
configurations to
T cell phosphoproteomics, and demonstrated the
immense potential to achieve greater qualitative and quantitative
insights into the
T cell signaling machinery. Finally, to support
the visualization, management, annotation, and analysis of this
proteomic data, we designed and implemented new tools to expedite
discoveries from large LC-MS datasets. The
subject of this work is
therefore the insights we have gained into the mechanisms governing
T cell activation and regulation as well as the technical and
technological innovations that made those insights
possible.

▼ L'objectif de ce travail était l'identification de nouveaux facteurs influençant la capacité des protéines à s'agréger ou ayant un i mpact sur l'agrégation d'autres protéines. Nous avons étudié l'influence des ligands anti-amyloïdes, interactions protéine-protéine et la glycation sur l'agrégation des protéine prion. La protéine prion a activée l'agrégation amyloïde d ans d'autres protéines habituellement stables. La glycation de la protéine prion entraîne une diminution de son amyloïdogénicité. En même temps, cette modification facilite légèrement l'agrégation amorphe de la protéine prion. Dans ce cas, l'effet antiagrégant total de la curcumine et de l'acide 3,4-diméthoxycinnamique a été affaibli, car a près la modification, l'agrégation s'est faite d avantage par la moyen non spécifique. L a présence de bêta-caséine avec une activité semblable à celle du chaperon supprime significative tout type d'agrégation des protéines prions, et combinaison de bêta-caséine et de ligands anti-amyloïdes est une méthode efficace d e suppression complète de l'amylose de la protéine prion. La bêta-caséine glyquée a montré s a capacité à s'agréger par elle-même et à f ormer des agrégats ordonnés fluorescent spécifiques avec un colorant thioflavine T. La présence de protéine prion a grandement facilité l a formation de ces agrégats, au contraire les ligands anti-amyloïdes l'ont supprimé. L'interaction de la protéine prion glyquée et de la b êta-caséine conduit à la formation des agrégats sphériques, que sont enrichis en structures a myloïdes pendant le traitement thermique. Dans ce cas, l’effet antiamyloïde de la curcumine et de l’acide 3,4-diméthoxycinamique disparaît presque complètement.
The main aim of this work was a search of new factors influencing the ability of proteins for aggregation themselves or impact the a ggregation of other proteins. We investigated the i nfluence of anti-amyloid ligands, protein-protein i nteractions and glycation on prion protein a ggregation. The prion protein activated amyloid a ggregation in other usually stable proteins. The glycation of the prion protein causes a decrease in its amyloidogenicity. At the same time, this m odification slightly facilitates the amorphous a ggregation of the prion protein. Also, the total a nti-aggregating effect of curcumin and 3,4- dimethoxycinnamic acid in this case was weakened, since after the modification the a ggregation was done more by non-specific m eans. T he presence of beta-casein with chaperone-like a ctivity significantly suppresses all types of prion protein aggregation, and a combination of beta- casein and anti-amyloid ligands was decided to b e an effective method of total prion protein a myloidosis suppression. The glycated beta- casein showed its ability to aggregate by itself and to form specific fluorescent ordered a ggregates with a thioflavin T dye. The presence of prion protein greatly facilitated the formation of t hese aggregates, unlike the anti-ligands, which i nhibits it. The interaction of glycated prion protein and beta-casein…

▼ The increasing demand for public security, including forensic security, has resulted in a substantial growth in the presence of surveillance camera networks (i.e., closed-circuit televisions, or CCTVs) in public areas. Significant improvements in the computer vision and machine learning fields have advanced the traditional surveillance camera network system (i.e., monitored by people) towards an intelligent surveillance system involving automated person detection, person tracking, activity recognition, and person re-identification. The field of person re-identification has recently received much attention from computer vision researchers. Appearance model-based features, which are detection features that are built based on elements of the subject's appearance, such as texture, colour, and clothes, are used in person re-identification. However, using the body shape (as one of the appearance model-based features) as a signature for person re-identification is an area of research still open for examination. This thesis presents the methodology, implementation, and experimental framework of a shape-based person re-identification system. The proposed system segments the human silhouette into eight different parts: Body, Head & Neck, Shoulders, Middle, Lower, Upper Quarter, Upper Half, Torso, and Lower Half. These segmentations are built based on anthropometry studies. This system exploits the shape descriptor information of these segments to build a subject-unique signature for person re-identification using a Generic Fourier Descriptor (GFD). The discrimination level of shape-based signatures are assessed by classifying them using image-based and video-based approaches. The image-based system classifies the signatures on a frame-by-frame basis using Linear Discriminant Analysis (LDA), which evaluates the feasibility of re-identifying subjects based on their shape static feature. The video-based approach exploits the signatures of the entire sequence (i.e., multiple frames) to re-identify subjects based on their dynamic features that occur within a collection of frames using Dynamic Time Wrapping (DTW). Comprehensive system outcomes for image-based and video-based systems are analysed by comparing the performance of both systems for each segment individually. Finally, a rank list fusion method, which combines the image-based generated rank lists so that the lists generated by all frames in each sequence are replaced by one rank list for the entire sequence, is implemented for performance enhancement. Extensive experiments were conducted using publicly available dataset to evaluate the proposed shape-based person re-identification. In scenarios where a subject who maintains the same appearance is identified and re-identified from the same angle, the image-based and video-based approaches were found to outperform a number of state-of-art systems. In situations where the subject is identified and re-identified from different viewing angles (inter-view) and with a change in appearance (cross-scenario), the results reflected a…

▼ One of the main objectives of this dissertation is to understand the nonlinear effects in optical fibres caused by stimulated Brillouin scattering (SBS). SBS is a nonlinear process, where, a sound wave is generated due to electrostriction effect that creates a travelling Bragg gratings and prevents delivery of high optical power beyond the SBS threshold. An improved full-vectorial numerically efficient Finite Element Method (FEM) based computer code is developed to study complex light-sound interaction in optical waveguides. An improved polar meshing technique is used to efficiently discretised the computational domain consisting of circular boundaries such as optical fibres. The existing structural symmetry of the optical waveguide is also exploited in both optical and acoustic modal solutions and only a half or quarter structure is simulated, as needed. This allows a more efficient element distribution on a smaller region compared to full structure with similar computational resources that result in the improved modal solution accuracy and reduced modal degeneration. The existence of spurious (non-physical) modes in full-vectorial acoustic modal solution and their elimination using the penalty method is also proposed and tested in this thesis. Penalty term consisting of the curl-curl section of the acoustic formulation enforces the acoustic field to suppress the rotational energy of the propagating acoustic wave. As a result of the penalty method, a significant improvement in the solution accuracy and quality of acoustic modes is demonstrated in both low and high index contrast optical waveguides. A standard single mode Germanium doped Silica fibre is used to study light sound interaction, and overlap of 93 % between fundamental optical and acoustic modes has been calculated. This acoustic-optic overlap is directly related to the calculation of the SBS threshold. A lower SBS overlap results in an increased SBS threshold and allows more power to be transferred in the optical fibre. Through rigorous numerical simulations, the fibre geometry and refractive index profile are modified, and a layer of a high acoustic index is introduced in the cladding such that the acoustic mode propagates in the cladding. The optical refractive indices of core and cladding are kept same while the acoustic index of 2nd layer is increased by doping it with Boron and Germanium (3.394% B2O3 + 2% GeO2). The acoustic mode completely shifts in the 2nd layer and as a result of this technique, an extremely low overlap of 2.5 % is calculated between optical and acoustic modes. Another objective of this research was to reduce the nonlinear effects in optical fibres is the use of large mode area (LMA) fibres such as few mode and multimode fibres. LMA fibres provide large effective area resulting in less nonlinear effects for a given power compared to single mode fibres. However, the existence of more than one mode may result in the inter-mode mixing and energy may transfer from one mode to its neighbouring propagating mode. Higher order modes of a…

▼ Bu çalışmada Öklidyen Düzlem üzerinde tanımlı Evritim (İnversion) dönüşümü
incelenmiştir.
İlk bölümde Evritimin tanımı ve genel özellikleri verildikten sonra bir noktanın evriği
sentetik ve analitik olarak gösterilmiştir. Daha sonra sırasıyla doğruların, çemberlerin ve
açıların evrikleri incelenip bunlarla ilgili bazı önemli teoremlere yer verilmiştir. Son olarak
Çifte Oran kavramı üzerinde durulmuştur.
İkinci bölümde ise öncelikle gerekli bazı tanımlara yer verilmiştir. Ardından Öklidyen
düzlemdeki evritim ile ilgili kavramların, Taksi düzlemi için karşılıkları
T-evritim adı altında
araştırılmıştır. Öklidyen düzlemde bir noktanın evriğini inşa ederken kullanılan sentetik
yöntem, Taksi düzleminde kullanılamamıştır. Bu sebeple yeni bir yöntem belirlenmiş ve bir
noktanın
T-evriği ayrıntılı olarak incelenmiştir. Son olarak ise doğruların
T-evriği üzerinde
çalışılmıştır.
Taksi Düzleminde Öklid düzlemine göre daha ayrıntılı bir inceleme yapmak
gerektiğinden ikinci bölümde nokta ve doğrunun
T-evriğini incelemekle yetinilmiştir.

▼ Once an immune response is initiated, a combination of several mechanisms coordinates and directs the homing of T cells to their target tissue. Co-stimulatory receptors expressed on the surface of T lymphocytes are known to actively regulate T cell motility and thus are crucial for regulating T cell migration. The B7 co-stimulatory receptor family members CD28 and CTLA-4 are well known to positively and negatively regulate effector T cell motility respectively. However, their effect on motility and subsequently migration has not been specifically studied in regulatory T cells (Tregs). Tregs are a CD4+ T cell subset fundamental for maintaining immune homeostasis and their role in controlling autoimmunity has been well established through a variety of experimental animal models. Tregs differ from conventional T cells in their expression of CTLA-4. While conventional T cells express CTLA-4 only after activation, Tregs are known to express this negative co-stimulatory receptor constitutively. Additionally, Tregs display a distinct metabolic phenotype to that of conventional T cells. This thesis examines the impact of both co-stimulatory receptors on Treg migration while taking in account the consequences of the concomitant delivery of signals from both. The data in this study suggests that glycolysis, rather than lipid oxidation induced by CD28 promotes Treg migration through glycolytic enzymes including glucokinase, whose expression in T cells was previously unknown. In contrast, CTLA-4 inhibits CD28 induced Treg migration via inhibition of these glycolytic enzymes. The therapeutic implications of these results in the context of disease and transplantation are discussed. CD31, an IgG like molecule, is expressed on a number of leukocytes including lymphocytes. In T cells, CD31 inhibits activation by recruiting phosphatases through its cytoplasmic ITIM domains and has thus been described as a co-inhibitory receptor. The role of this co-receptor in the regulation of T cell migration is investigated in the last part of this thesis. Our observations suggest that CD31 selectively signals in activated T cells to regulate their migration in response to inflammatory chemokines, revealing an additional role of this receptor in regulating T cell-mediated inflammation.

▼ Malaria is a global life-threatening disease
responsible for 400,000 deaths each year. Chronic infection with
Plasmodium species drives CD4+ T cell exhaustion, which is
characterised by the inability of effector CD4+ T cells to produce
effector cytokines, proliferate and increased T cell apoptosis. T
cell exhaustion significantly impairs parasite control during blood
stage malaria. However, the molecular mechanisms promoting CD4+ T
cell exhaustion during malaria are poorly understood. Using a model
antigen-specific CD4+ T cell system, we have shown that effector
CD4+ T cells rapidly become functionally exhausted during P.yoelii
infection. The degradation of the effector CD4+ T cell response
appeared to relate to the loss of MHC II-TCR signalling, as
blockade of MHC II signalling, post priming, did not exacerbate
effector T cell dysfunction and attrition during malaria. However,
apparent loss of MHC II activation during infection was not due to
alterations in CD4+ T cell compartmentalisation, or inability of
effector CD4+ T cells to interact with antigen presenting cells
(APC) during infection. Instead, we propose that negative signals
from co-inhibitory receptors subvert peptide MHC II-TCR signals in
effector CD4+ T cells, contributing to T cell exhaustion during
blood stage malaria. To further investigate the role of
co-inhibitory receptors in promoting CD4+ T cell exhaustion during
malaria, we administered antagonistic antibodies against TIGIT and
PD-L1. Dual blockade of TIGIT and PD-L1 significantly enhanced
parasite control, which correlated with an increased level of
systemic interferon gamma (IFNg) and an enhanced T follicular
helper response during infection. Surprisingly, however, dual
blockade of TIGIT and PD-L1 did not significantly improve effector
CD4+ T cell function. Thus, blockade of TIGIT and PD-1 signalling
pathways cannot prevent CD4+ T cell exhaustion during malaria. We
also investigated the synergistic role of Tim3 and PD-1 in
promoting CD4+ T cell exhaustion during malaria. Interestingly,
Tim3 was transiently expressed on effector CD4+ T cells and was
downregulated as T cell exhaustion was established during
infection. In agreement, co-blockade of Tim3 and PD-L1 failed to
improve CD4+ T cell functionality during P.yoelii infection,
suggesting that Tim3 does not contribute to CD4+ T cell exhaustion
during malaria. Collectively, this thesis has shown that effector
CD4+ T cell exhaustion is not associated with the inability of T
cells to form stable interactions with APC during infection, but
instead we propose that multiple immunoregulatory pathways act in
parallel to orchestrate T cell exhaustion during blood stage
malaria.

▼ Upon infection, naive T lymphocytes proliferate and differentiate into highly specialized cell types to combat the pathogen: CD4+ T cells into specialized helper subsets and CD8+ T cells into armed effectors. Although the majority of the antigen specific T cells from both lineages will die as the immune response wanes, a few will survive indefinitely to establish memory populations, providing long-lived protection against reinfection. Transcriptional regulators of the E-protein and Id families are important arbiters of both T cell development in the thymus, and differentiation in response to infection. We and others, have shown that E/Id proteins cooperate to balance expression of genes that control CD8+ T cells throughout their differentiation, however, their role in the differentiation of CD4+ helper subsets has not been studied as extensively. My recent work uncovered a role for Id and E proteins in the differentiation of CD4+ T helper 1 (TH1) and T follicular helper (TFH) cells following infection. I found that that TH1 cells showed more robust Id2 expression than that of TFH cells, and depletion of Id2 via RNA-mediated interference increased the frequency of TFH cells. Furthermore, TH1 differentiation was blocked by Id2 deficiency, which led to E-protein-dependent accumulation of effector cells withmixed characteristics during viral infection and severely impaired the generation ofTH1 cells following infection with Toxoplasma gondii. Finally, the TFH cell-definingtranscriptional repressor Bcl6 bound the Id2 locus, which provides a mechanismfor the bimodal expression of Id2 and reciprocal development of TH1 cells and TFHcells. Investigation of Id3 revealed that naive CD4+ T cells expressed high levelsof Id3, which, when compared to TH1 cells, is maintained by TFH cells followingLCMV infection. I found that Id3 was required to restrict unchecked differentiationof TFH and GC TFH cells. Lastly, I showed that expression of Id3 marks CD4+ T cellswith multipotent recall potential following LCMV infection. These studies informthe functional relevance of E/Id proteins in CD4+ T cells, given the importance ofleveraging the recall capabilities of memory T cells to fight reinfection.

The Application of ANN and ANFIS Prediction Models for Thermal Error Compensation on CNC Machine Tools.

▼ Thermal errors can have significant effects on Computer Numerical Control (CNC) machine tool accuracy. The errors come from thermal deformations of the machine elements caused by heat sources within the machine structure or from ambient temperature change. The effect of temperature can be reduced by error avoidance or numerical compensation. The
performance of a thermal error compensation system essentially depends upon the accuracy and robustness of the thermal error model and its input measurements. This thesis first reviews different methods of designing thermal error models, before concentrating on employing Artificial Intelligence (AI) methods to design different thermal prediction models. In this research work the Adaptive Neuro-Fuzzy Inference System (ANFIS) is used as the backbone for thermal error modelling. The choice of inputs to the thermal model is a non-trivial decision which is ultimately a compromise between the ability to obtain data that sufficiently correlates with the thermal distortion and the cost of implementation of the necessary feedback sensors. In this thesis, temperature measurement was supplemented by direct distortion measurement at accessible locations. The location of temperature measurement must also provide a representative measurement of the change in temperature that will affect the machine structure. The number of sensors and their locations are not always intuitive and the time required to identify the optimal locations is often prohibitive, resulting in compromise and poor results. In this thesis,
a new intelligent system for reducing thermal errors of machine tools using data obtained from thermography data is introduced. Different groups of key temperature points on a machine can be identified from thermal images using a novel schema based on a Grey system theory and Fuzzy C-Means (FCM) clustering method. This novel method simplifies the modelling process, enhances the accuracy of the system and reduces the overall number of inputs to the model, since otherwise a much larger number of thermal sensors would be required to cover the entire structure.
An Adaptive Neuro-Fuzzy Inference System with Fuzzy C-Means clustering (ANFIS-FCM) is then employed to design the thermal prediction model. In order to optimise the approach, a parametric study is carried out by changing the number of inputs and number of Membership Functions (MFs) to the ANFIS-FCM model, and comparing the relative robustness of the designs. The proposed approach has been validated on three different machine tools under different operation conditions. Thus the proposed system has been shown to be robust to different internal heat sources, ambient changes and is easily extensible to other CNC machine tools.
Finally, the proposed method is shown to compare favourably against alternative approaches such as an Artificial Neural Network (ANN) model and different Grey models.

▼ Crossing the Franco-Swiss border, the Large Hadron Collider (LHC), designed to collide
7 TeV proton beams, is the world’s largest and most powerful particle accelerator –
the operation of which was originally intended to commence in 2008. Unfortunately, due
to an interconnect discontinuity in one of the main dipole circuit’s 13 kA superconducting
busbars, a catastrophic quench event occurred during initial magnet training, causing
significant physical system damage. Furthermore, investigation into the cause found that
such discontinuities were not only present in the circuit in question, but throughout the entire
LHC. This prevented further magnet training and ultimately resulted in the maximum
sustainable beam energy being limited to approximately half that of the design nominal,
3.5-4 TeV, for the first three years of operation (Run 1, 2009-2012) and a major consolidation
campaign being scheduled for the first long shutdown (LS 1, 2012-2014).
Throughout Run 1, a series of studies attempted to predict the amount of post-installation
training quenches still required to qualify each circuit to nominal-energy current levels.
With predictions in excess of 80 quenches (each having a recovery time of 8-12+ hours)
just to achieve 6.5 TeV and close to 1000 quenches for 7 TeV, it was decided that for
Run 2, all systems be at least qualified for 6.5 TeV operation. However, even with all interconnect
discontinuities scheduled to be repaired during LS 1, numerous other concerns
regarding circuit stability arose. In particular, observations of an erratic behaviour of magnet
bypass diodes and the degradation of other potentially weak busbar sections, as well as
observations of seemingly random millisecond spikes in beam losses, known as unidentified
falling object (UFO) events, which, if persist at 6.5 TeV, may eventually deposit sufficient
energy to quench adjacent magnets.
In light of the above, the thesis hypothesis states that, even with the observed issues,
the LHC main dipole circuits can safely support and sustain near-nominal proton beam
energies of at least 6.5 TeV.
Research into minimising the risk of magnet training led to the development and implementation
of a new qualification method, capable of providing conclusive evidence that
all aspects of all circuits, other than the magnets and their internal joints, can safely
withstand a quench event at near-nominal current levels, allowing for magnet training to
be carried out both systematically and without risk. This method has become known as
the Copper Stabiliser Continuity Measurement (CSCM). Results were a success, with all
iii
circuits eventually being subject to a full current decay from 6.5 TeV equivalent current
levels, with no measurable damage occurring.
Research into UFO events led to the development of a numerical model capable of
simulating typical UFO events, reproducing entire Run 1 measured event data sets and
extrapolating to 6.5 TeV, predicting the likelihood of UFO-induced magnet quenches. Results

▼ The principle aims of this thesis were to investigate the influence of intrinsic navigational cues in virtual environments and video games. Modern video games offer complex environments that may reflect real world spaces or represent landscapes from fantasy and fiction. The coherent design of these spaces can promote natural navigational flow without the requirement for extraneous guidance such as maps and arrows. The methods that designers use to create natural flow are complex and stratified utilising principles rooted in urban architectural design and navigational cues that are intrinsic to real-world wayfinding scenarios. The studies presented in this thesis analysed not only these commonly used architectural cues but also the potential for the reinforcing of these cues by the addition of lighting, visual and auditory cues. The primary focus of this thesis was a systematic and quantitatively rooted analysis of the impact lighting has on navigation and the levels at which variance in lighting makes a quantifiable difference to navigational choices within a virtual environment. The findings of this thesis offer clear guidance as to the influence that lighting has within virtual environments and specifies that thresholds at which the inclusion of guidance lighting begins to affect navigational choices and the levels that players become conscious of these cues. The thesis also analyses the temporal thresholds for the detection of changes in contrast, hue and texture within an environment. The relationship of other intrinsic cues such as the potential reinforcement or cue competition effects of both audio and other visual cues, for instance motion are quantitatively analysed. These data were reflected in the form of a series of heuristic design principles that augment those that underpin architectural and environmental design considerations by for instance suggesting levels of saliency for lighting cues or reinforcing existing cues via supporting audio guidance.

▼ Electro-luminescent optical cells form the first layer in the unique sound of an optical compressor and are the main element in achieving gain reduction. This research was carried out in order to identify key low-level parameters within the optical cell assembly that relate to the colouration added to the musical signal. Variations of an optical cells were built, each with a modification to the identified parameter (electro-luminescent panel, light dependent resistor, exposure area, etc.). Objective analysis was performed, and multiple tests were carried out to determine the performance characteristics of each modified cell. Various stimuli were utilised which included broadband pink noise, band-limited pink noise (63 Hz band and 1 kHz band) and sine wave bursts. Further to the individual cell testing, audio measurements and analysis of the resultant signal utilising the cells within an audio compressor were undertaken.
Key findings of the report conclude that the optical cells do exhibit a ‘memory effect’ determined by the amount of compression applied. They also have a two-staged attack characteristic that is independent from the audio stimuli and a different timing response based on the combination of the two elements inside the optical cell (the Light Dependent Resistor and the Electro-Luminescent panel). Further to this, it was determined that the attack/release characteristics of the optical compressor and the Total Harmonic Distortion (THD) levels of the compressed audio stimuli changed as a direct result of the optical cell’s modified parameters. Moreover, it was proved that some electro-luminescent panels do exhibit a colour-shift phenomenon and a frequency-dependent brightness that affect the cell’s compression characteristics with different audio stimuli. Further to the findings, additional attack and release characteristics are proposed based on parameter modifications.

▼ The modern society is in the transition process from the Information Age to the Interaction Age so the attitude of academics and students towards Internet use is continuously changing.
This study aims to investigate the attitudes of lecturers and students from Al-Zawiya University (AZU), Libya, towards the use of Internet technology for academic purposes and to formulate a set of recommendations for upgrading the quality and effectiveness of ICT implementation within the School of Engineering from AZU.
The action research approach is used to develop a novel framework for increasing the effectiveness of ICT implementation in AZU. The framework aims to improve the Internet skills of lecturers and students, increase the impact of the Internet on their academic efficiency, solve the problems they face while using the Internet, and increase their satisfaction with the Internet facilities provided by AZU. This new framework is built on the basis of different existing models and frameworks (a two-dimensional model for ICT integration in education, the ASSURE model, an framework for HE internationalisation, the ICube model for teaching and learning activities in modern Higher Education institutions).
The study includes an analysis of existing Internet use by academic staff and students which looks at various features of Internet usage, including purposes for using the Internet and users’ level of satisfaction with the Internet facilities provided by the university. The SPSS package is employed for qualitative analysis of sixty students’ answers to the questionnaires and shows that people’s skills, computing resources and infrastructure influence the efficacy of integrating computers into HE.
Semi-structured interviews are used to determine the attitudes of twelve academics towards use of the Internet in two departments – Department of English Language (DEL) and Department of Electrical Engineering (DEE). The qualitative analysis of academics’ responses identifies the cognitive, performance and affective components of their outlook towards use of the Internet for teaching and research. In addition, the relationship between their answers and the research hypotheses shows that a combination of individual and social factors affects users’ perspectives regarding Internet usage.
Finally, a set of recommendations for the enhancement of ICT implementation within the School of Engineering at Al-Zawiya University in Libya is formulated, aiming to enhance the quality of teaching, learning and research activities and the level of students’ satisfaction with the technology-enhanced approach to learning. The findings of this thesis might be of interest to managers, academics and other people involved in the design and development of strategies for ICT implementation in Libyan universities and similar developing countries.

▼ Artificial Intelligence research in the past few years has been increasingly focusing on games, with Real Time Strategy games being of particular interest. However, one of the main tools used in the creation of agents in these environments has quite a steep learning curve for entry into development, leading to some potential entry barriers that new AI developers have to overcome to get into the field.
This project aims to investigate ways in which these entry barriers can be lowered. Particular interest is taken in the potential future application of techniques found in Visual Programming Languages. With this view, a library of tools to help new AI developers is created and tested before being given to members of the Bot Development community to provide their technical assessment feedback, and has been given to new developers with no previous experience with the subject area for their evaluation on how effective these tools were in easing the process of starting out with development.
This report describes the research, the planning and testing of this library, and the conclusions drawn from the subsequent evaluation of the tools.

▼ The cumulative global photovoltaic (PV) capacity has been growing exponentially around the world, especially due to the installation of grid connected photovoltaic (GCPV) plants. Fault detection and analysis are important for the efficiency, reliability and safety of solar photovoltaic (PV) systems. Even
This thesis reports the results of the research work conducted to invent novel fault detection algorithms and evaluate their deployment in multiple existing PV installation, and empirically validate their performance.
A major contribution of this thesis is the development of PV fault detection algorithms based on two indicators named power ratio (PR) and voltage ratio (VR). Both ratios are used to identify the type of the fault that occurs in the PV modules, in PV string, and/or in maximum power point tracking (MPPT) unit.
Three AI based algorithms were also used to detect faults in PV modules. The first algorithm uses six regions of the power and voltage ratio in order to detect faults in PV systems. The average detection accuracy for the algorithm is equal to 94.74%. However, Mamdani Fuzzy Logic system has been used to enhance the occurrence of fault detection in the PV installations which resulted in an increase to 99.12%.
The second proposed PV fault detection algorithm detects defective bypass diodes in PV modules using Mamdani Fuzzy Logic. Whereas, a third PV detection algorithm is based on artificial neural networks (ANN) networks. Four different ANN models have been modelled, which can be classified as follows:
- 2 inputs, 5 outputs using 1 hidden layer
- 2 inputs, 5 outputs using 2 hidden layers
- 2 inputs, 9 outputs using 1 hidden layer
- 2 inputs, 9 outputs using 2 hidden layers
The output results for the last ANN network had the highest overall fault detection accuracy of 92.1%.
In this thesis, the development of two hot spot mitigation techniques used in PV modules will be discussed. These techniques are capable of enhancing the output power of PV modules which are affected by hot spots and partial shading conditions. The detection of hot spots was captured using i5 FLIR thermal imaging camera.
Finally the thesis describes the impact of PV micro cracks on the output power of PV modules. A new statistical analysis approach using T-test and F-test was used to identify the significance impact of the cracks on the output power performance of the PV modules. This is developed using LabVIEW software.

▼ Modern Supervisory Control and Data Acquisition (SCADA) systems are essential for monitoring and managing electric power generation, transmission and distribution. In the age of the Internet of Things, SCADA has evolved into big, complex and distributed systems that are prone to conventional in addition to new threats. So as to detect intruders in a timely and efficient manner a real time detection mechanism, capable of dealing with a range of forms of attacks is highly salient. Such a mechanism has to be distributed, low cost, precise, reliable and secure, with a low communication overhead, thereby not interfering in the industrial system’s operation.
In this commentary two distributed Intrusion Detection Systems (IDSs) which are able to detect attacks that occur in a SCADA system are proposed, both developed and evaluated for the purposes of the CockpitCI project. The CockpitCI project proposes an architecture based on real-time Perimeter Intrusion Detection System (PIDS), which provides the core cyber-analysis and detection capabilities, being responsible for continuously assessing and protecting the electronic security perimeter of each CI. Part of the PIDS that was developed for the purposes of the CockpitCI project, is the OCSVM module. During the duration of the project two novel OCSVM modules were developed and tested using datasets from a small-scale testbed that was created, providing the means to mimic a SCADA system operating both in normal conditions and under the influence of cyberattacks.
The first method, namely K-OCSVM, can distinguish real from false alarms using the OCSVM method with default values for parameters ν and σ combined with a recursive K-means clustering method. The K-OCSVM is very different from all similar methods that required pre-selection of parameters with the use of cross-validation or other methods that ensemble outcomes of one class classifiers. Building on the K-OCSVM and trying to cope with the high requirements that were imposed from the CockpitCi project, both in terms of accuracy and time overhead, a second method, namely IT-OCSVM is presented. IT-OCSVM method is capable of performing outlier detection with high accuracy and low overhead within a temporal window, adequate for the nature of SCADA systems.
The two presented methods are performing well under several attack scenarios. Having to balance between high accuracy, low false alarm rate, real time communication requirements and low overhead, under complex and usually persistent attack situations, a combination of several techniques is needed. Despite the range of intrusion detection activities, it has been proven that half of these have human error at their core. An increased empirical and theoretical research into human aspects of cyber security based on the volumes of human error related incidents can enhance cyber security capabilities of modern systems. In order to strengthen the security of SCADA systems, another solution is to deliver defence in depth by layering security controls so as to reduce…

▼ This thesis investigates how different variations of presentational performance feedback influences the motivation of a learner in a computer-assisted musical instrument tutoring context. Further, the thesis overviews methods to increase students’ engagement with the learning process.
Positive and negative content balance in performance feedback is proposed through conducting user testing and evaluation. User testing was carried out using an online browser-based guitar tuition app developed for the purpose of this thesis. A custom-built application allowed full control over varying the balance of positive and negative content within performance feedback for different testing groups.
Last experiment was aimed to find aspects of gamification to promote and encourage users to better themselves and to keep learning.
A brief description of up-to-date technology used to design and develop the guitar tuition software product is described.
Despite the results being inconclusive they appear to indicate that presenting negative feedback is detrimental to the learners’ motivation. Furthermore, gamifying the learning experience and introducing competitive nature of games into musical instrument tuition appear to increase learners’ engagement, and prevent the learner drifting into boredom.

▼ The rapid depletion of power sources has remarkably impacted the transport sector, where the costs of the freight transportation are rising dramatically every year. Significant endeavours have been made to develop innovative means of transport that can be adopted for economic and environmental friendly operating systems. Transport pipelines consider one such alternative mode that can be used to transfer goods. Although the flow behaviour of a solidliquid mixture in hydraulic capsule pipeline is quite complicated, due to its dependence on a large number of geometrical and dynamic parameters, it is still a subject of active research. In addition, published literature is extremely limited in terms of identifying the impacts of the capsules shape on the flow characteristics of pipelines. The shape of these capsules has a significant effect on the hydrodynamic behaviour within such pipelines.
This thesis presents a computational investigation employing advanced Computational Fluid Dynamics (CFD) based tool to simulate the capsules flow of varied shapes quantified in form of a novel shape factor in a vertical hydraulic capsule pipeline. The 3-D Dynamic Meshing technique with Six Degrees of Freedom approach is applied for numerical simulation of unsteady flow fields in vertical capsule pipelines. Variations in flow related parameters within the pipeline have been discussed in detail for geometrical parameters associated with the capsules and flow conditions within Hydraulic Capsule Pipelines (HCPs).
Detailed quantitative and qualitative analyse has been conducted in the current research. The qualitative analysis of the field of the flow comprises descriptions of the pressure and velocity distribution within the pipeline. The investigations have been conducted on the flow of spherical, cylindrical and rectangular shaped capsules each one separately for offshore applications. As it can be notice that the flow behaviour inside HCP relies on the flow conditions and geometric parameters. The development of novel predictive models for pressure drop and capsule velocity is considered as one of the goals that have been achieved in this research. Moreover, the flow of a variety of different shaped capsules, in combination, has also been investigated based on the impact of the order of the capsule shape within the vertical pipeline. It has been found that the motion of mixed capsules along the pipeline shows a significant variation comparing to the basic capsules shapes for the same shape being transported across the pipelines.
Capsule pipeline designers need accurate data regarding the pressure drop, holdup and the shape of the capsules etc., at early design phases. The methodology of optimisation is developed based on the least cost principle for vertical HCPs. The inputs to the predictive models are the shape factor of the capsule and solid throughput demanded of the system, while the outcomes represent the pumping power demanded for the capsule transportation process and the optimal diameter of the HCP.

▼ For many centuries, researchers and scholars have been effortlessly trying to harvest natural energy resources, such as wind energy, solar energy and geothermal energy, due to the diminution of fossil fuels and their harmful effects on the surrounding environment. The wind has been shown to possess an incredible amount of power, which can be harnessed using wind turbines. Wind turbines transform the kinetic energy available in the free stream wind into mechanical energy by a rotor, from which power can be generated.
Wind turbines can be broadly classified into two main categories, depending on the orientation of their axis of rotation; Horizontal Axis Wind Turbines (HAWT) and Vertical Axis Wind Turbines (VAWT). VAWTs are more suitable for the urban environment due to their low start-up torque.
Extensive research has been carried out in improving the design and performance of a VAWT. However, a number of key issues have been highlighted after conducting an extensive literature; these key issues form the scope of this research.
The current study focuses on optimising the distance between VAWT’s placed side by side linearly, by analysing the flow around a single VAWT using advanced numerical modelling tools. This study is carried out by analysing the wake region formed by the flow field under various free stream wind velocities. Furthermore, maximum wake region will be identified to measure the maximum distance the free stream wind velocity can occupy in the VAWT vicinity.
Finally, a novel mathematical model that predicts the optimal distance required to place a side by side VAWT under various flow conditions will be developed. It is expected that this study will be able to optimise the spacing between VAWTs in a wind farm.

▼ The use of three-dimensional (3D) surround sound systems has seen a rapid increase over recent years. In two-dimensional (2D) loudspeaker formats (i.e. two-channel stereophony (stereo) and 5.1 Surround), horizontal interchannel decorrelation is a well-established technique for controlling the horizontal spread of a phantom image. Use of interchannel decorrelation can also be found within established two-to-five channel upmixing methods (stereo to 5.1). More recently, proprietary algorithms have been developed that perform 2D-to-3D upmixing, which presumably make use of interchannel decorrelation as well; however, it is not currently known how interchannel decorrelation is perceived in the vertical domain. From this, it is considered that formal investigations into the perception of vertical interchannel decorrelation are necessary. Findings from such experiments may contribute to the improved control of a sound source within 3D surround systems (i.e. the vertical spread), in addition to aiding the optimisation of 2D-to-3D upmixing algorithms.
The current thesis presents a series of experiments that systematically assess vertical interchannel decorrelation under various conditions. Firstly, a comparison is made between horizontal and vertical interchannel decorrelation, where it is found that vertical decorrelation is weaker than horizontal decorrelation. However, it is also seen that vertical decorrelation can generate a significant increase of vertical image spread (VIS) for some conditions. Following this, vertical decorrelation is assessed for octave-band pink noise stimuli at various azimuth angles to the listener. The results demonstrate that vertical decorrelation is dependent on both frequency and presentation angle – a general relationship between the interchannel cross-correlation (ICC) and VIS is observed for the 500 Hz octave-band and above, and strongest for the 8 kHz octave-band. Objective analysis of these stimuli signals determined that spectral changes at higher frequencies appear to be associated with VIS perception – at 0° azimuth, the 8 and 16 kHz octave-bands demonstrate potential spectral cues, at ±30°, similar cues are seen in the 4, 8 and 16 kHz bands, and from ±110°, cues are featured in the 2, 4, 8 and 16 kHz bands. In the case of the 8 kHz octave-band, it seems that vertical decorrelation causes a ‘filling in’ of vertical localisation notch cues, potentially resulting in ambiguous perception of vertical extent. In contrast, the objective analysis suggests that VIS perception of the 500 Hz and 1 kHz bands may have been related to early reflections in the listening room.
From the experiments above, it is demonstrated that the perception of VIS from vertical interchannel decorrelation is frequency-dependent, with high frequencies playing a particularly important role. A following experiment explores the vertical decorrelation of high frequencies only, where it is seen that decorrelation of the 500 Hz octave-band and above produces a similar perception of VIS to broadband…

▼ The rapid and significant development of communications links between satellites has
made it possible to use various applications such as relay voice, video, multimedia, etc. As a result, a great deal of research has been done in this field during the last few years to reduce power consumption and increase transmission reliability.
This thesis is concerned with an analysis of intersatellite links in free space, with optical links using laser sources being considered in particular. It includes a literature survey and a thorough theoretical investigation into designing the model of the link in free space. This thesis describes the novel technique of designing the optical receiver that consists of PIN photodiode as a photodetector, Semiconductor optical amplifier (SOA) and a 3rd order Butterworth filter with central decision detection. In addition, it discusses the use of several different coding schemes for use in such links: multiple pulse position modulation (MPPM); digital pulse position modulation (DPPM);
Dicode pulse position modulation (Dicode PPM).
This novel technique of an optical receiver is investigated and new work is presented in order to examine the noise performance of this optical receiver and hence determine its sensitivity and the number of photons received for a specified error rate.
Further new work is carried out to compare these coding schemes in terms of error weightings and coding efficiency through showing how the PCM error rate is affected by false alarm and erasure errors for MPPM, DPPM and Dicode PPM coding 3, 4, 5 and 6 bits of PCM. An original maximum likelihood sequence detector (MLSD) is presented in this thesis in order to perform these comparisons. In addition, computer simulations models (using MCAD) are performed to compare these three coding schemes operating with 3, 4, 5 and 6 bits of PCM in terms of sensitivity and
bandwidth efficiency. These comparisons show that MPPM coding 3, 4, 5 and 6 bits of PCM is the appropriate coding scheme to be used in optical inter-satellite links in free space and PCM data rates of 1 Gbit/s.

▼ Current trends in technology are leading to a need for ever smaller and more complex featured surfaces. The techniques for manufacturing these surfaces are varied but are tied together by one limitation; the lack of useable, on-line metrology
instrumentation. Current metrology methods require the removal of a workpiece for characterisation which leads to machining down-time, more intensive labour and generally presents a bottle neck for throughput.
In order to establish a new method for on-line metrology at the nanoscale investigation are made into the use of optical fibre interferometry to realise a compact probe that is robust to environmental disturbance. Wavelength tuning is combined with a dispersive element to provide a moveable optical stylus that sweeps the surface. The phase variation caused by the surface topography is then analysed using phase shifting interferometry.
A second interferometer is wavelength multiplexed into the optical circuit in order to track the inherent instability of the optical fibre. This is then countered using a closed loop control to servo the path lengths mechanically which additionally counters external vibration on the measurand. The overall stability is found to be limited by polarisation state evolution however.
A second method is then investigated and a rapid phase shifting technique is employed in conjunction with an electro-optic phase modulator to overcome the polarisation state evolution. Closed loop servo control is realised with no mechanical movement and a step height artefact is measured. The measurement result shows good correlation with a measurement taken with a commercial white light interferometer.

▼ The area of Content-Based Image Retrieval (CBIR) deals with a wide range of research disciplines. Being closely related to text retrieval and pattern recognition, the probably most serious issue to be solved is the so-called \semantic gap". Except for very restricted use-cases, machines are not able to recognize the semantic content of digital images as well as humans.
This thesis identifies the requirements for a crucial part of CBIR user interfaces, a multimedia-enabled query language. Such a language must be able to capture the user's
intentions and translate them into a machine-understandable format. An approach to tackle this translation problem is to express high-level semantics by merging low-level image features. Two related methods are improved for either fast (retrieval) or accurate(categorization) merging.
A query language has previously been developed by the author of this thesis. It allows the formation of nested Boolean queries. Each query term may be text- or content-based and the system merges them into a single result set. The language is extensible by arbitrary new feature vector plug-ins and thus use-case independent.
This query language should be capable of mapping semantics to features by applying machine learning techniques; this capability is explored. A supervised learning algorithm based on decision trees is used to build category descriptors from a training set. Each resulting \query descriptor" is a feature-based description of a concept which is comprehensible and modifiable. These descriptors could be used as a normal query and return a result set with a high CBIR based precision/recall of the desired category. Additionally, a method for normalizing the similarity profiles of feature vectors has been
developed which is essential to perform categorization tasks.
To prove the capabilities of such queries, the outcome of a semi-supervised training session with ≤ ave-one-object-out" cross validation is compared to a reference system. Recent work indicates that the discriminative power of the query-based descriptors is similar and is likely to be improved further by implementing more recent feature vectors.

▼ This Thesis examines the role and limitations of voice biometrics in the contexts of security and
for crime reduction. The main thrust of the Thesis is that despite the technical and non-technical hurdles that this research has identified and sought to overcome, voice can be an effective and sustainable biometric if used in the manner proposed here. It is contended that focused and continuous evaluation of the strength of systems within a solid framework is essential to the development and application of voice biometrics and that special attention needs to be paid to human dimensions in system design and prior to deployment.
Through an interdisciplinary approach towards the theme reflected in the title several scenarios
are presented of the use of voice in security / crime reduction, crime investigation, forensics and surveillance contexts together with issues surrounding their development and implementation.
With a greater emphasis on security-oriented voice verification (due to the diversity of the usage scenarios and prospect of use) a new framework is presented for analysis of the reliability and security of voice verification.
This research calls not only for a standard evaluation scheme and analytical framework but also takes active steps to evaluate the prototype system within the framework under various conditions. Spoof attacks, noises, coding, distance and channel effects are among the factors that are studied. Moreover, an additional under-researched area, the detection of counterfeit signals, is also explored.
While numerous technical and design contributions made in this project are summarised in chapter 2, the research mainly aims to provide solid answers to the high-level strategic questions. The Thesis culminates in a synthesis chapter in which realistic expectations, design requirements and technical limitations of the use of voice for criminological and security applications are
outlined and areas for further research are defined.

▼ The widely application of XML has increasingly required high security. XML security confronts some challenges that are strong relating to its features. XML data integrity needs to protect element location information and contextreferential meaning as well as data content integrity under fine-grained security
situations. XML data authentication must satisfy a signing process under a dependent and independent multi-signature generation scenario. When several different sections are encrypted within the XML data, it cannot query the
encrypted contents without decrypting the encrypted portions. The technologies relating to XML security demand further development.
This thesis aims to improve XML security relative technologies, and make them more practicable and secure. A novel revocation information validation approach for X.509 certificate is proposed based on the XML digital signature technology. This approach reduces the complexity of XKMS or PKI systems because it eliminates the requirement for additional revocation checking from XKMS or CA. The communication burden between server and client could be alleviated.
The thesis presents the context-referential integrity for XML data. An integrity solution for XML data is also proposed based on the concatenated hash function. The integrity model proposed not only ensures XML data content integrity, but also protects the structure integrity and elements’ context relationship within an XML data. If this model is integrated into XML signature technology, the signature
cannot be copied to another document still keeping valid.
A new series-parallel XML multi-signature scheme is proposed. The presented scheme is a mixed order specified XML multi-signature scheme according to a dependent and independent signing process. Using presented XML data integrity-checking pool to provide integrity-checking for decomposed XML data, it makes signing XPath expression practicable, rather than signing XML data itself.
A new labeling scheme for encrypted XML data is presented to improve the efficiency of index information maintenance which is applied to support encrypted XML data query processing. The proposed labelling scheme makes maintenance
index information more efficient, and it is easy to update XML data with decreasing the number of affected nodes to the lowest. In order to protect
structural information for encrypted XML data, the encrypted nodes are removed from original XML data, and structural information is hidden.
A case study is carried out to demonstrate how the proposed XML security relative approaches and schemes can be applied to satisfy fine-grained XML
security in calibration certificate management.

▼ This thesis documents a project undertaken at the University of Huddersfield between October 2009 and August 2010 to setup a High Performance Computing (HPC) resource, which would serve the University’s research community by providing a robust computing solution. This thesis will look at all the various kinds of requirements different fields have, with regard to a computing solution, and the tools available to meet these specific needs. This report serves as a manual for any small to medium sized institution that
considers setting up a local HPC resource. It looks at all considerations regarding hardware, software, licensing, infrastructure, HR etc for setting up a centralised computing resource with sustainability and robustness being the central aim of the proposed resource. The possibilities of cross-continent and cross-institution
collaboration using Clusters and Grid technologies are explored and the method for connecting to the UK eScience community through the NGS is explained.

▼ Serious games are an established pedagogical tool, with applications in a wide variety of fields. Although this includes the area of medical training, there is currently no podiatric orthopaedic training simulator. We attempt to overcome one of the obstacles to the creation of this kind of simulator, namely how to simulate podiatric bone surgery. In order to simulate this surgery appropriately, it is necessary to be able to cut through a virtual representation of a patient's foot on-screen in realtime. We investigate several methods of cutting through simulated objects in general, and evaluate their usefulness in simulating real-time interactive bone surgery. We determine that none of these conventional methods are fully suitable and instead propose, develop and test a method using planar slicing of polyhedral mesh geometry.
In addition, we describe and test some optimizations to vertex and index buffer representations of polyhedral meshes. These optimizations alleviate a performance bottleneck constraining the speed at which progressive mesh modifications can be made, facilitating the near-real-time modi�cation rate required for simulating surgery. We also investigate the use of haptic feedback to simulate the feel of surgery, and employ two games technologies to increase the realism of the simulation: particle engines and stereoscopic 3D rendering.

▼ This paper presents an automated method for preparing digital X-rays for use by a procedural mesh generator. This process will facilitate the generation of a 3D polygon mesh depicting the bones contained within the X-ray image. The process of preparing the image involves identifying and retaining bone elements whilst removing any superfluous aspects contained within the image, such as text and orientation markers. This will allow a virtual podiatric surgical simulator, VirtuOrtho to feature patient specific bone models generated from the processed X-rays. The algorithm additionally employs parallel processing techniques that are capable of utilizing either multi-core CPUs or a GPU to help to reduce the computational time required to process an image. The relative performance of the multi-core CPU implementation will be compared and contrasted to the performance of the GPU version. As part of the image processing algorithm, two GPGPU algorithms for median filter are proposed: a caching method improves upon the fast, small-radius median filter (McGuire, 2008) and a second method which uses a histogram based technique (Huang et al., 1979) to facilitate filters with large-radius masks to be processed using the GPU.
