Investigation of the oxidation behaviour of the polycrystalline Co-Ni base superalloys
Creators: name: Binti Ismail, Farah
Publisher: name: Imperial College London
Year: 2017

description: The initial study reported here focused on the oxidation of Co-Al-W alloys containing nickel (29-34 at. %) and chromium (12-17 at. %) additions with the objective of improving the oxidation resistance of these alloys at high temperatures (800-850 °C) for high-pressure turbine discs. Starting with the analysis in the as-atomised powder, the material was then consolidated using hot-isostatic pressing (HIP) and a two-stage HIP was performed to optimise the precipitation of carbides. Solution heat-treated and aged samples were studied in terms of the effects of additional alloying elements on the alloys’ oxidation behaviour after high temperature exposures. Isotopic oxidation tracer experiments were carried out at 800-850 °C in isotopically enriched oxygen (16O- and 18O-) to elucidate the oxidation mechanisms. Oxidation mechanisms in alloys with different Co-Ni ratio and Cr, Al contents were investigated in polycrystalline cobalt-base superalloys. Various characterisation techniques were used to investigate the oxidation mechanisms such as FEG-SEM, STEM with EDX, high resolution TEM, FIB-SEM, and FIB-SIMS were applied. The various phases present in the initial and oxidised microstructures have been established, together with the oxidation behaviour of the alloy. After oxidation at 800 °C for 200 hours, the alloys exhibit a multi-layered structure, consisting of an outer oxide scale with a continuous alumina layer at the oxide-alloy interface. The bulk metal consisting of a cobalt solid solution containing secondary phases (Co3W and CoAl), carbides precipitates (Ta-Zr carbides) and fine γ’ (Co3(Al-W)) precipitates. The oxidation behaviour on shot-peened surfaces was studied and it was found that shot-peening does not affect the oxidation resistance directly but it does alter the sub-surface region causing recrystallisation and thus opening up diffusion paths for cations/anions diffusions. The study of oxygen transport mechanisms using 18O2 as a tracer element has revealed that an outer chromium-rich oxide layer formed at the metal surface during the initial oxidation and continuous inner alumina layer is primarily formed subsequently. This alumina layer appears to effectively block the diffusion of oxygen to the metal/oxide interface and oxidation proceeds by outward cation diffusion. This study demonstrates that protective oxide scales can be formed in cobalt-base superalloys.

description: Negli anni del regime fascista l’ideale della donna come «angelo del focolare» si conciliava male con la partecipazione femminile alle attività sportive. Il fascismo, tuttavia, riservò una grande attenzione allo sport, servendosene sia come fattore di educazione e socializzazione delle masse, sia come veicolo di propaganda. La vicenda di Ondina Valla – vincitrice della corsa degli 80 metri a ostacoli alle Olimpiadi del 1936 – racchiude in sé questa contraddizione, giacché da un lato il regime intendeva utilizzare a livello propagandistico i successi dell’atleta, dall’altro si trovava di fronte a una figura che non rifletteva il modello di donna che si voleva imporre.

title: Development of an observational coding scheme for parental behaviour in a play-based instructional context with 5- to 7-year-olds
Creators: name: Jakubauskaite, Vaida
Publisher: name: University of Kent
Year: 2022

description: This PhD thesis outlines and explains the development of an inductive coding scheme designed for the analysis of parents' behaviour during play-based instructional parent-child interactions with 5- to 7-year-old children. Parents and children were video-recorded collaborating on a problem-solving puzzle in a laboratory for 10 minutes. Five-minute fragments of the same task were selected, and parents' behaviour was analysed inductively (i.e., using a data-driven "bottom-up" approach) to establish sufficient segmentation and coding granularity. This required identifying fine-grained behavioural segments, considering all observable aspects of parents' behaviour, and naming the behaviours appropriately. This thesis explains and illustrates with data examples five stages of the coding scheme development: pre-pilot coding scheme development, pilot coding scheme development, coder training, pilot coding scheme testing and finalising the coding scheme, and implementation of the final coding scheme. Throughout these stages, the coding scheme was tested and improved based on the insights gained through the inter-rater agreement (IRA) assessment and coding disagreement discussions with the independent coders. Satisfactory IRA and the coders' understanding of the coding scheme demonstrated that the final coding scheme was successfully developed, comprising 18 codes (e.g., praise, direct instruction, assistive clue) within 8 distinct categories (e.g., positive, control, guidance). A coding manual was developed for future researchers' use containing the coding and segmentation rules, final coding scheme (code definitions, guiding questions, code differentiation, code examples and non-examples), coder training plan, coding procedures, and recommendations for improving coding accuracy.

description: Le stesse prevenzioni fisiologiche, moraliste, maschiliste con le quali s’era cercato di frenare, tra Otto e Novecento, l’uso della bicicletta da parte delle donne, furono all’origine delle remore nutrite nei riguardi delle corse atletiche femminili di durata. Resistenze potentemente rafforzate da un episodio che segnò per molto tempo lo sviluppo di queste pratiche a livello muliebre. Ci si riferisce in specie alla gara degli 800 metri disputata nell’ambito dell’Olimpiade di Amsterdam (1928). Corsa di mezzofondo che, per l’affaticamento denotato da talune atlete nella gara di finale, indusse la IAAF e il CIO da escluderla dal programma olimpico sino al 1960. Il contributo analizzerà la contrastata storia degli 800 femminili a livello internazionale e nazionale, soffermandosi con attenzione sulla prima atleta italiana, la napoletana Gilda Jannaccone, che, proprio negli anni ’60, risollevò questa disciplina dal grave ritardo tecnico in cui versava.

Dificuldades na Recuperação da Informação em Bibliotecas Escolares

description: É bastante complexa a realidade das bibliotecas escolares quanto ao tratamento técnico documental, nomeadamente, quanto aos processos de análise, indexação e recuperação da informação. Contudo, em grande parte delas os documentos (sobretudo as monografias) percorrem quase todo o circuito técnico, só não chegando à indexação. Qual a razão desta situação? Que dificuldades se levantam aos professores bibliotecários na assunção desta tarefa tão importante em qualquer biblioteca? Para além da mais evidente – trata-se da tarefa técnica mais complicada, dirigida ao conteúdo do documento, à sua componente intelectual – não tem havido, nos últimos tempos, uma mesma ideia quanto à política de indexação a seguir e aos instrumentos a utilizar. Várias razões estão na base desta realidade, das quais destacamos duas: a maior parte dos professores destacados nas BE não têm formação técnica, de nível superior, nesta área; as escolas têm um público utilizador muito heterogéneo (do pré-escolar ao pré-universitário), tanto em termos etários, como em termos de conhecimentos e de interesses.

Nesse sentido, a taxionomia do Portal evoluiu rapidamente para uma visão organizada por eventos da vida do Cidadão, com temas próximos à vida quotidiana, permitindo uma navegação intuitiva e amigável. Procurando garantir o aproveitamento de novos conceitos de relacionamento através da Web, o Portal evoluiu, também, para a disponibilização de serviços transaccionais complexos, como a “Alteração de Morada” ou para serviços simples, baseados na lógica Web 2.0, como a iniciativa “A Minha Rua”, paradigma da aproximação da Administração ao Cidadão ao permitir o contacto directo com o poder local. Estes e outros serviços similares são reveladores do futuro da administração electrónica em Portugal.

Machine learning methods for audio-visual event analysis
Creators: name: Pu, Jie
Publisher: name: Imperial College London
Year: 2020

description: This thesis studies machine learning techniques for localizing, separating and recognizing audio-visual events. Until recently, the widely-used methods for analyzing audio-visual events involves either laborious pre-processing/post-processing steps to handle videos, or a huge amount of training data to supervise their learning processes. To overcome these limitations, we aim to develop novel approaches that have one end-to-end framework, and much less dependence on training data than state-of-the-art deep-learning approaches. In particular, we propose novel low-rank and sparse matrix decomposition methods, kernelized matrix decomposition methods and deep neural networks for audio-visual event analysis, with a particular focus on their data-efficiency and computational-efficiency. First, we investigate the problem of blind audio-visual localization and separation, which aims to localize visual objects associated with an audio signal and simultaneously separate the audio signal from irrelevant audio components. To this end, a novel low-rank and sparse matrix decomposition method is devised, where we use a sparse matrix capturing the correlated components between visual and audio modalities, and hence uncovering the sound source in visual modality and the associated sound in audio modality. After that, we propose a novel kernelized sparse and low-rank decomposition method, which generalizes the linear correlation of our low-rank and sparse model into non-linear ones. This leads to superior performances in the application of active speaker detection and localization in audio-visual recordings. Given the recent surge of deep learning, we also propose a novel deep low-rank and sparse model, which uses deep neural networks to achieve low-rank and sparse decomposition. It is a further extension of our kernelized matrix decomposition method, where the non-linear correlation between visual and audio modalities is captured by deep networks. Finally, we have worked on the problem of sound event detection and localization. A novel filterbank learning approach is proposed, which takes the raw waveform as input and produces its auditory spectro-temporal representation. In contrast to standard convolutional neural networks that learn all elements of each filter, the proposed filters are parameterized with only two learnable variables. This offers the interpretability of our model after training, and greatly lessen its requirement for training data.

The identification of gaze behaviour associated with decision-making in surgery: an eye- tracking study
Creators: name: Ashraf, Hajra
Publisher: name: Imperial College London
Year: 2019

description: Adverse surgical events remain at an unacceptably high level despite multiple global safety initiatives being introduced to practise over the last 15 years. As yet, however there is no conclusive evidence to identify whether physiological markers can be used to predict whether a surgeon will make an error. The aim of this thesis is to identify whether physiological metrics, specifically gaze related metrics can be used to predict whether a surgeon is going to make an error. Thus, my research hypothesis was gaze metrics can be analysed to provide a greater understanding of perceptual contributions to decision- making in healthcare and aid in the formulation of innovative solutions. The research question was initially approached by the undertaking of a literature review, outlining the current knowledge surrounding the uses of eye- tracking technology in healthcare, the findings of which are outlined in chapter one. Next, I undertook two studies recruiting surgeons to perform a series of laparoscopic cholecystectomy tasks on the LapMentor Simbionix trainer. Fatigue severity score (FSS) was calculated prior to the task. Physiological metrics, including gaze tracking, heart rate and skin conductance were measured while they completed the tasks. LightGBM and CatBoost were used to predict the physiological metric most useful in predicting whether a surgeon was about to make an error. My studies indicated that the most predictive feature was the correlation of the skin conductance measure against itself shifted by two time steps (4ms, or 250hz). Skin conductance was twice as likely to successfully predict impending error compared to heart rate and fatigue severity scale. Gaze metrics were found to be unimportant thus rendering our hypothesis incorrect. However, when I added gaze features, overall model performance improved by 6.4%. This leads us to surmise that gaze metrics are relevant, however future work would need to establish the importance of this improvement in performance. This work advances our understanding of physiological changes that occur during decision making and has important implications in the surgical field, as skin conductance could potentially be used as a warning system to indicate when surgeons are at high risk of making an error. The potential for reduction in surgical error rate and improvement in patient safety are important factors to consider.

Stories from the womb: investigating the relationship between joint shape emergence and mechanical stimulation in the murine embryo
Creators: name: Sotiriou, Paraskevi (Vivien)
Publisher: name: Imperial College London
Year: 2020

description: Embryonic movements play an important role in joint development. Multiple animal model studies on embryos have shown that absent or abnormal musculature affect aspects of skeletal development, such as joint shape formation, joint cavitation and mineralisation. However, joint morphogenesis is the least researched aspect of joint development. In this doctoral dissertation, embryonic mouse forelimbs and hindlimbs at developmental stage (Theiler Stage) TS23 with normal, reduced, or absent muscle, and embryonic forelimbs and hindlimbs at TS24 and TS27 with normal or absent muscle were imaged in three dimensions. Virtual segmentation of skeletal rudiments and rigid image registration to reliably align rudiments with each other were performed, enabling repeatable assessment and measurement of joint shape differences. The shoulder, elbow, hip and knee joint shapes between normal, reduced muscle and absent muscle groups at TS23 were assessed. So were the differences in joint shape and mineralisation between normal and absent muscle embryos at TS24 and TS27. Cavitation in normal and muscleless-limb joints at TS24 and TS27 was also studied. It was shown that joint shapes are differentially affected by reduced or absent skeletal muscle with the elbow joint being the most affected. Surprisingly, reduced muscle often affected joint shape more than absent muscle, highlighting a complex interplay between muscle mass and joint morphogenesis. Counter intuitively, it was found that - as development progressed - when skeletal muscle was absent, different joints had recovered their shapes at different degrees. Hindlimb joints had completely recovered and the proportion of mineralisation of the muscleless-limb rudiments was similar to that of the same stage control rudiments at TS27. Uncavitated muscleless-limb joints at TS24 had not cavitated much or at all at TS27. These findings uncover complex interactions between skeletal development and muscle contractions and are relevant to human developmental disorders of the skeleton implicating abnormal fetal movements.

Intrinsic kinetics of 'frustrated Lewis pair' hydrogenation catalysis
Creators: name: Allcock, Nathan James
Publisher: name: Imperial College London
Year: 2020

description: The past decade has seen the discovery and exploration of frustrated Lewis pair chemistry; these novel main group systems have been investigated in the context of small molecule activation, particularly their role in dihydrogen activation and hydrogenation catalysis. However, studies thus far are often proof-of-concept and detailed intrinsic kinetic investigations into reaction mechanism are limited. The focus of this thesis has been to address this gap with a detailed study of the mechanistic pathway of frustrated Lewis pair catalysed hydrogenation reactions. The initial part of this thesis was dedicated to the development of a method capable of measurement of intrinsic kinetics of hydrogenation, followed by a study of hydrogen mass transfer effects. Three methods for measurement of intrinsic kinetics in a Parr 5500 laboratory scale reactor were compared and contrasted: hydrogen pressure monitoring, reaction sampling, and analysis via an FT-IR transmission cell. Sampling reaction mixture for ex situ measurement via 1H NMR was selected as a robust and preferred method for monitoring hydrogenation of organic substrates. A set of boundary conditions for measurement of intrinsic kinetics were then established, through measurement of the rate of hydrogen absorption into 1,2-dichlorobenzene, toluene and 1,4-dioxane solvents over a range of temperatures and pressures. The second part of the thesis begins with an investigation of the robustness of several Lewis acid catalysts under typical hydrogenation conditions described in the literature. The remainder of the thesis is dedicated to a detailed mechanistic study of a particularly moisture tolerant tin catalyst, triisopropyltin(IV)triflate, in particular the catalytic hydrogenation of imine and carbonyl substrates; an investigation of potential rate determining factors concludes that dihydrogen activation is the rate determining step of reaction. It is envisaged that successful catalyst designs in the future must address both the efficiency of dihydrogen activation and catalyst inhibitory effects; it is recommended that a study via in situ FT-IR analysis will aid development in this area.

description: Os resultados da investigação em, muitos países, bem como os temas emergentes na reflexão sobre as práticas e nos conteúdos diariamente adicionados à informação difundida sobre Educação e Desenvolvimento confirmam o papel chave de bibliotecas escolares de qualidade, geridas por pessoal especializado e a tempo inteiro nas aprendizagens das gerações que vão à escola. As recentes evoluções tecnológicas, tal como os sinais que as diversas crises económicas, políticas e sociais apresentam, reafirmam a actualidade e a pertinência da visão assumida pelos Manifestos da IFLA/Unesco, acentuando a influência das medidas políticas que promovem as bibliotecas escolares no combate à exclusão social e na qualidade de vida das sociedades, e dos seus cidadãos e cidadãs, no futuro. Os desafios colocam-se ao nível dos governos, mas também na dimensão da cultura e e da criação, e, evidentemente, nas redes de profissionais envolvidos quer na Gestão da Informação e Documentação, quer na Educação e Formação, com natural destaque, em sociedades democráticas, para os que conseguem mobilizar-se em associações ou grupos mais ou menos informais de interesse.

description: Ao mesmo tempo que a Humanidade enfrenta problemas de sustentabilidade cada vez mais complexos, são cada vez maiores os recursos à nossa disposição para tirar partido da inteligência distribuída por todo o planeta. Os esforços dos vários países para promover a educação e a economia permitem agora aos indivíduos participarem activamente na inovação empresarial e social, dando respostas mais céleres e diversificadas aos problemas económicos, sociais e ambientais que nos afligem a todos. A web 2.0 veio trazer novas formas de organização social, onde o conhecimento individual serve de base à partilha e co-construção de ideias e tecnologias que integram a inteligência de muitos. As Universidades e Politécnicos são centros de excelência na construção de conhecimento científico e tecnológico. Portugal não mais se poderá dar ao luxo de deixar que grande parte do conhecimento criado no âmbito da formação de mestrado e doutoramento se dissipe de forma inconsequente para a economia e sociedade em geral. Este conhecimento precisa ser valorizado e transferido para quem dele pode beneficiar. Este pode ser feito por todos nós que aprendemos e ensinamos no Ensino Superior, através das ferramentas que a estratégia de Crowdsourcing coloca à nossa disposição. A comunicação focará os conceitos e práticas de crowdsourcing que estão a revolucionar a forma como as empresas, e a sociedade em geral, participam e implementam a inovação.

description: En la perspectiva clásica de la teoría sobre el conocimiento organizacional, uno de los principales enfoques ha sido de qué manera se puede asegurar que el conocimiento pueda ser almacenado y organizado. Sin embargo, en buena parte de los estudios sobre conocimiento organizacional los estudiosos han encontrado que la información que alimenta la creación de conocimiento es informal y fluye por canales informales. El concepto que ha sido usado de manera recurrente es el de conocimiento tácito, para agrupar ese conocimiento que no está codificado y en buena medida es informal. Así que en el presente trabajo se explora la influencia de la transferencia informal en el conocimiento tácito de la organización. La exposición esta compuesta con las siguientes partes: a) Conocimiento tácito y; b) Transferencia informal del conocimiento organizacional.

description: A harmonização da tributação a nível europeu, apresenta-se como um factor essencial para a prossecução dos objectivos comunitários. No entanto, apesar das tendências de convergência e dos esforços da UE nesse sentido, a verdade é que as disparidades continuam a existir no âmbito fiscal, sendo evidente que os dispositivos legais de cada um dos Estados Membros continuam a imperar no que toca ao âmbito tributário. Tendo em conta a realidade em que se insere a VAT Systems, a actualização constante no que respeita à legislação de cada um dos 27 Estados Membros, e o tratamento de toda a informação inerente é crucial para a prossecução dos objectivos da empresa.

description: Abstract: Due to the fact that borrowers can utilize a variety of credit forms that are linked to lending facilities, there are several ways to establish a credit facility. A worrying issue in the banking sector, meanwhile, is that the loans are not easily recouped following financing for the borrowers. Unpaid loans, or non-performing loans (NPLs), are becoming more common and are having an impact on the financial sector. The problem of nonperforming loans (NPLs) is getting worse for banks, despite the fact that the banking industry is expanding steadily. When it comes to a country's economy, non-performing loans are the main problem. This study examines two well-known banks in Bangladesh and draws comparisons between them regarding the important matter of nonperforming loans. Commercial banking services are available in Bangladesh from both private sector institutions and the state-owned Janata Bank Limited (JBL) and Dutch Bangla Bank Limited (DBBL). Janata Bank had a nonperforming loan percentage of 12.34% in 2015, and DBBL had a proportion of 3.7% due to insufficient funding and an inefficient recovery mechanism. In terms of nonperforming loans, the two banks couldn't be more different, both in terms of the calculated number and the cause of the increase in NPLs. It is common practice to use statistical data, such as a percentage, to ascertain the causes of increasing NPLs. I advised the two banks on how to decrease nonperforming loans and recover their funds after undertaking a thorough investigation.
