MESSINA, FRANCESCO. « IMPROVING THE EOB TOOLBOX FOR GRAVITATIONAL WAVE DATA ANALYSIS ». Doctoral thesis, Università degli Studi di Milano-Bicocca, 2021. http://hdl.handle.net/10281/299793.
Texte intégralThe parameter estimation of gravitational wave events detected by LIGO and Virgo relies on analytical waveforms models, possibly calibrated (or informed) by Numerical Relativity simulations. The effective-one-body (EOB) model is one of the main analytical models available that can be efficiently used for analyzing both black hole and neutron star binaries. In this script we I) improve it in its various sectors, with the final aim to build a model that includes all the physical information available: in particular, the higher subdominant multipoles information, that is useful to optimize GW data analysis’ angular resolution [1, 4, 5, 7]; II) use it to develop high-order fast PN approximants for Bayesian analysis in LIGO and Virgo pipelines [3]; III) use it to study the self-spin effects of binary Neutron Stars on their own waveform [2]. One of the central building blocks of the EOB model is the factorized and resummed (circularized) multipolar post-Newtonian (PN) waveform introduced in Ref. [8] for nonspinning binaries. In Ref. [4], we extend up to ` = 6 (i.e. to high multipoles) the resummation approach of Nagar and Shah [9], since it has a better analytical/numerical relativity agreement than its precursor [8]. Ref. [4], updated to the case of a spinning particle of Schwartzschild problem in Ref. [5], has been used in order to update the spin-aligned, quadrupolar EOB model TEOBResumS, a C++ code [1] available in the LIGO Advanced Library (LAL) and cited in the GW catalogue [10], to a multipolar version [7]. Therefore, following the EOB-PN expansion technique defined in [11], Ref. [3] leads to a fast and accurate 5.5PN phenomenological approximant that, by including more point-mass information than the standard 3.5PN one, optimizes the tidal-parameter estimation of BNS data analysis. In Ref [2], we incorporate the EOS-dependent selfspin terms in TEOBResumS at next-to-next-to-leading (NNLO) order, together with other (bilinear, cubic and quartic) nonlinear-in-spin effects (at leading order, LO). Here, with the same toolbox used in Ref. [3], we study the EOS dependence of the self-spin effects and show that the next-to-leading order (NLO) and NNLO monopole-quadrupole corrections yield increasingly phase-accelerating effects compared to the corresponding LO contribution; that the standard TaylorF2 post-Newtonian (PN) treatment of NLO (3PN) EOS-dependent self-spin effects makes their action stronger than the corresponding EOB description; and, finally, we obtain a tail-augmented TaylorF2 approximant that yields an analytically simplified, EOB-faithful, representation of the EOS-dependent self-spin phasing that can be useful to improve current PN-based (or phenomenological) waveform models for inspiralling neutron star binaries.

Texte intégralThe demand of electric vehicles (EV) grows rapidly, with an increase in Europe from 734 newly registered EVs in 2010, to 550 000 in 2019 (European Environment Agency, 2020). While this trend continues, the demand of lithium ion batteries (LIB) follows a similar path. With electrified transportation being an important sub-goal on the road to net-zero greenhouse gas emissions, the European Union shows great interest for the development of the market. The EU is therefore developing a new directive for batteries in which EV batteries (EVB) have more focus than in theearlier Batteries Directive from 2006. In the new directive, producers of EVBs will have an extended responsibility, meaning that they are responsible for the batteries at end of life (EOL). This study aims at investigating the current supply-chain and design of EVBs, as well as the current and upcoming technical solutions for recycling of EVBs, in order to discuss how EVB manufacturers can and should act regarding recycling, as a response to the new EU directive on batteries. The study is delimited to supply-chain and material sourcing; how to design batteries for recycling; and the current technical solutions for EOL batteries. The research is solely based on literature review of scientific publications, technical reports and forecasts of market and technical development. The results of the literature shows a general consensus that there will be shortage of lithium andother critical materials for EVB manufacturing which ultimately will lead to unstable prices. The updated battery directive will most certainly set clear goals of higher levels of recycled material in new EVBs, but it will also implicate that batteries that can be used for other applications than EVs need to be reused until EOL. It has been concluded that designing for recycling will be importantfor making the recycling process economically viable. We have discussed the possibilities and challenges for EVB manufacturers associated with leasing EVBs as a business model where they can secure batteries and by extension material for recycling at EOL. The positioning in the value chain has also been discussed. We see that there is an apparent tradeoff between integrating upstream and remaining flexible. Integrating upstream will enable control over batteries at EOL as well as the opportunity to choose whether to sell the recycled lithium or to use it in their own production.

Texte intégralBAKGRUND: Fysisk aktivitet på recept (FaR) innebär att en läkare skriver ut en anpassad träningsform till patienten istället för medicin, eller i kombination med medicin. Aktiviteten blir en del i behandlingen. Eftersom många idag inte följer rekommendationerna för fysisk aktivitet uppstår på sikt en rad folkhälsosjukdomar. FaR främjar hälsan och förebygger sjukdom. SYFTE: Syftet med den här uppsatsen är att undersöka huruvida FaR ur ett patientperspektiv upplevs vara en effektiv och fungerande behandlingsmetod. METOD: En kvalitativ ansats har använts. Semistrukturerade intervjuer har genomförts via telefon. Målgruppen var vuxna personer över 18 år som fått FaR. RESULTAT: Det som framkom av intervjuerna var att upplevelsen av FaR i stort sett var positiv och att de flesta förstod varför det var viktigt med fysisk aktivitet. Besöket hos sjukvården höjde direkt motivationen till att träna, men sjönk om inte uppföljning skedde. Trots den positiva upplevelsen så hade det i flera fall behövts mer råd och hjälp. Det saknades i många fall en kontaktperson eller samordnare som patienten kunde vända sig till. SLUTSATS: Genom att få mer hjälp med motivation och stöttning hade troligen flera av respondenterna fått bättre resultat av FaR.

Texte intégralSyfte: Studiens syfte är att identifiera, utforma och applicera en metod för operativ produktionsplanering. Ändamålet med metoden är att den tar hänsyn till artiklarnas respektive efterfrågemönster vilket avgör valet av beräkningsmodell samt att metoden tar även hänsyn till produktionens kapacitetsbegränsning ställare. Resultatet kan appliceras som beslutsunderlag för små samt medelstora tillverkande företag som står inför en expansion. Forskningsfråga: Följande forskningsfråga var objektet för denna studie. Hur skulle en lämplig operativ planering formas utefter artiklarnas specifika egenskaper och deras olikartade efterfrågemönster hos små och medelstora tillverkande företag med kapacitetsbegränsningen ställare? Metod: Studien är en kvalitativ en-fallstudie med kvantitativa inslag. Den empiriska data som använts i studie än insamlad genom ostrukturerade samt semistrukturerade intervjuer där snöbollseffekten tillämpats och även observationer har utförts. Resultat: Studien har möjliggjort en högre utnyttjandegrad av kapacitetsbegränsningen ställare, genom att framta standardiserade blockstorlekar. Första steget var att identifiera efterfrågemönster som de studerade artiklarna kunnat kategoriseras in i. Efterfrågemönstret har tillämpats för att kunna använda rätt beräkningsmodell på rätt artikel. Beräkningsmodellen standardiserades därefter genom tillämpning av PoT för att kunna erhålla standardiserade blockstorlekar. Metoden illustrerades i ett Gantt-schema för att påvisa dess användbarhet.

amurlu, and Garzan crude oil samples were tested experimentally using retort and microwave heating techniques. Many parameters like heating time, porosity, water saturation were studied. To enhance the efficiency of the processes three different iron powders (i.e.
Fe, Fe2O3, and FeCl3) were added to the samples and the doses of the iron powders were optimized. While crude oil viscosities were measured to explain the fluid rheologies, since it is impossible to measure the shale oil viscosity at the laboratory conditions due to its very high viscosity, shale oil viscosities were obtained numerically by using the electrical heating option of a reservoir simulator (CMG, STARS 2007) by matching between the laboratory and numerical oil production and temperature distribution results. Then the field scale simulations for retorting of oil shale and crude oil fields were conducted. Since the microwave heating cannot be simulated by CMG, STARS, microwave heating was modeled analytically. In order to explain the feasibility of heating processes, an economic evaluation was carried out. The experimental, numerical, and analytical results show that field scale oil recovery from oil shales and heavy crude oils by electrical and electromagnetic heating could be economically viable. While microwave heating is advantageous from an operational point of view, retorting is advantageous if the technically feasibility of the study is considered.

Texte intégralO presente estudo tem como objectivo fundamental investigar qual o significado do papel atribuído pelo Banco Central Europeu (BCE) ao agregado monetário largo M3 na condução da política monetária na zona euro. Partindo de um breve enquadramento teórico quanto ao papel atribuído pelo BCE à moeda, procede-se a uma análise empírica, baseada em vectores autoregressivos (usando essencialmente as variáveis macroeconómicas: taxa de crescimento do M3, hiato do M3 em termos reais, taxa de inflação e hiato do produto), no sentido de detectar evidência empírica de suporte ao papel proeminente que foi atribuído à moeda pelo BCE. As principais conclusões deste estudo apontam para a existência de uma enorme sensibilidade em torno da definição da taxa de inflação. No entanto, partindo-se da taxa de inflação medida pelo deflator do Produto Interno Bruto (PIB), a evidência empírica parece sugerir uma certa primazia como indicador de evolução futura dos preços o hiato do M3 em termos reais quando comparado quer com a taxa de crescimento do agregado monetário largo M3 quer com o hiato do produto.
The main target of this study is to investigate the meaning of the role assigned by the European Central Bank (ECB) to the broad monetary aggregate M3 in its conduction of the monetary policy for the euro area. The work begins with a brief theoretic framing of the role assigned to the money by ECB, which is followed by an empirical analysis, based on autoregressive vectors (employing essentially the following macroeconomic variables: growth rate of M3, real gap of M3, inflation rate and output gap), with the objective of detecting empirical evidence that support the prominent role of money assigned by the ECB. The main conclusions of this study support the existence of a high sensibility to the definition of the inflation rate. However, starting with the best measure of inflation rate based on Gross Domestic Product (GDP) deflator, the empirical evidence supports a certain primacy, as future inflation indicator, to the real gap of M3 rather than to the growth rate of M3 or output gap.

Texte intégralThis thesis is motivated by the diagnosis and the evaluation of the dementia diseasesand with the aim of predicting if a new recorded gaze presents a complaint of thesediseases. Nevertheless, large-scale population screening is only possible if robust predictionmodels can be constructed. In this context, we are interested in the design and thedevelopment of automatic prediction models for specific visual content to be used in thepsycho-visual experience involving patients with dementia (PwD). The difficulty of sucha prediction lies in a very small amount of training data.Visual saliency models cannot be founded only on bottom-up features, as suggested byfeature integration theory. The top-down component of human visual attention becomesprevalent as human observers explore the visual scene. Visual saliency can be predictedon the basis of seen data. Deep Convolutional Neural Networks (CNN) have proven tobe a powerful tool for prediction of salient areas in static images. In order to constructan automatic prediction model for the salient areas in natural and intentionally degradedvideos, we have designed a specific CNN architecture. To overcome the lack of learningdata we designed a transfer learning scheme derived from bengio’s method. We measureits performances when predicting salient regions. The obtained results are interestingregarding the reaction of normal control subjects against degraded areas in videos. Thepredicted saliency map of intentionally degraded videos gives an interesting results comparedto gaze fixation density maps and other reference models

Texte intégralIn this thesis, we investigate several topics related to the interannual climatic modes in the tropical Atlantic. Statistical analyses allows us to extract the two main dominant modes of interannual variability: an equatorial mode and a meridional mode. The equatorial mode is responsible for Sea Surface Temperature (SST) anomalies mainly found in the Gulf of Guinea and is linked to variations of the sea-level slope in the equatorial band. It is due to dynamic feedbacks between zonal wind, sea level and SST. The meridional mode is characterised by inter-hemispheric SST fluctuations and is controlled by dynamic and thermodynamic feedbacks between the wind, evaporation and SST. After quantifying the coupling between key variables involved in the meridional mode, we develop a conceptual model to explain the main mechanisms responsible for meridional mode oscillations. The model shows that the meridional mode results from the superposition of a self-sustaining mechanism based on positive and negative feedbacks generating regular oscillations of high frequency (2-3 years) and another low frequency oscillation mechanism (4-9 years) related to the influence of ENSO. As the evolution of these two modes is strongly linked to the meridional shift of the Intertropical Convergence Zone (ITCZ) and associated rainfall maximum, we identify the signature of these modes on Sea Surface Salinity (SSS) using in situ observations and a regional numerical simulation. Oceanic and/or atmospheric processes responsible for the signature of each mode are also identified through a mixed-layer salt budget in the validated model. The salt balance reveals that the atmospheric forcing, related to the ITCZ migration, controls the equatorial region while the advection, due to the modulation of current dynamics, the vertical gradient and mixing at the base of the mixed layer, explains SSS variations in regions under the influence of plumes. Finally, we study the Equatorial Kelvin wave characteristics and influences on the density that are involved in the meridional and equatorial mode connection processes, using a very simplified model of gravity wave propagation along the equator. After a brief description of this model, which was initially constructed to study dynamics in the equatorial Pacific, we apply it to the specific case of the equatorial Atlantic by validating its analytical and numerical solutions under adiabatic conditions.

Texte intégralA avaliação do desempenho dos docentes, a medição da eficácia dos seus ensinamentos, foi desde sempre um assunto polémico e de difícil execução. Uma nova política de avaliação surge, articulada a grandes e profundas mudanças no estatuto da carreira docente, intocado desde a sua concepção nos inícios dos anos 90. Estas mudanças vieram no seguimento de um conjunto de alterações legais, com reflexos nas condições de trabalho dos trabalhadores da administração pública, entre os quais se incluem os professores, nomeadamente: o aumento da idade de aposentação, a suspensão de progressões na carreira por um período superior a dois anos (28 meses) e a contenção de aumentos salariais. As mudanças no estatuto da carreira docente visavam uma melhoria da eficácia do desempenho docente, propondo-se a excelência e a distinção de desempenhos, num campo onde sempre pairou a igualdade. Um novo modelo de avaliação, mais abrangente, diversificado e regulador surge regulamentado nos finais de Janeiro de 2008. É também com este decreto, 2/2008 de 10 de Janeiro, que se instala uma discórdia total entre a classe visada e a tutela, com diversas manifestações, greves e protestos encabeçadas pela classe docente, unida como nunca visto e totalmente contra as pretensões governamentais. A necessidade de regrar as medidas destinadas à classe docente com as já anteriormente tomadas para grande parte dos trabalhadores da administração pública (SIADAP) ―impôs, por sua vez, um prazo curto para a introdução da avaliação do desempenho dos professores e para retomar o processo de progressão na carreira. A resistência por parte dos professores reflecte ainda as dificuldades criadas pela operacionalização de um modelo tão abrangente num curto espaço de tempo, aliadas a algumas consequências inesperadas do modelo‖ (OCDE, 2009. p.1). Esta investigação surge na altura em que a carreira docente sofre profundas alterações, principalmente nas regras de acesso e progressão. O novo modelo de avaliação de desempenho docente, acima referido, tem um impacto mais expressivo na carreira, pois impede que a progressão dos docentes se faça quase automaticamente. Surge uma avaliação com uma carga negativa, pois é esta que dita quem vai deixar de progredir rapidamente (mais do que com uma carga positiva, indicando quem vai progredir rapidamente). Com este cenário delineado, exigir-se-á um rigor absoluto e insenção à avaliação de desempenho, sem o qual se produzirá a sua descredibilização global. A implementação do novo modelo de avaliação revela-se assim um empreendimento ―crítico‖. Com este trabalho pretende-se compreender as dificuldades sentidas na implementação do novo modelo de avaliação de desempenho docente. Inicia-se com uma construção conceptual do que é o profissional da educação, o que se entende por desenvolvimento profissional, competência profissional e eficácia pedagógica. São abordadas as questões inerentes à avaliação formativa e sumativa, são exemplificados alguns modelos de avaliação de desempenho realizados nos Estados Unidos tendo como referência o resultado dos alunos. A natureza exploratória deste estudo legitimou o recurso aos seus principais actores, os professores, procurando identificar as suas perspectivas e preocupações. Neste estudo de caso descreve-se o processo de implementação do novo ―modelo‖ de avaliação de desempenho numa escola de 2º e 3º ciclos do Ensino Básico, integrada numa zona de grande afluência populacional multicultural, ao longo dos primeiros dois anos, correspondente ao primeiro ciclo de vigência do processo de avaliação. Para elucidar as dificuldades sentidas e as reacções provocadas, a investigação mostra os problemas, tensões e contradições de avaliação de desempenho, instituída no fogo cruzado entre a retórica da melhoria da qualidade e um dispositivo pouco orientado para a gestão formativa do desempenho, entre a suposta ingenuidade auto-crítica e a auto-apresentação estratégica, num jogo de recompensas e sansões dependentes da avaliação e de uma avaliação conduzida por critérios e padrões de avaliação que permanecem ocultos num nevoeiro que envolve todo o processo, marcado por avanços e recuos sucessivos.
L'évaluation du rendement des enseignants, mesurer l'efficacité de leur enseignement a toujours été un sujet controverse et difficile d’appliquer. Une nouvelle politique d'évaluation se pose, en liaison avec des changements majeurs et profonds dans le statut de la carrière d'enseignant intacte depuis sa création dans les années 90. Ces modifications sont entrées après une série de changements législatifs, avec un reflet sur les conditions de travail des travailleurs de l'administration publique, parmi lesquels les enseignants, notamment : l'augmentation de l'âge de la retraite, la suspension des progressions de carrière pour une période de plus de deux ans (28 mois) et le confinement des augmentations de salaire. Ces modifications visaient à améliorer l'efficacité de la performance de l'enseignement, en proposant l'excellence et la distinction de la performance dans un domaine où nous avons toujour eu l'égalité. Un nouveau modèle d'évaluation, plus complet, diversifié et régulateur fait son apparition en fin Janvier 2008. C'est avec ce décret, 2 /2008 du 10 Janvier, qui installe un désaccord entre la classe d’enseignement et le gouvernement, avec un certain nombre de manifestations de protestation et de grèves menées par les professeurs, unie comme jamais auparavant et totalement contre la volonté du gouvernement. La nécessité de mesures réglés, de la profession enseignante, à celles déjà prises pour la plupart des travailleurs de l'administration publique (SIADAP) "imposes à son tour, un court délai pour l'introduction de l'évaluation du rendement des enseignants et reprendre le processus de développement de carrière. La résistance des enseignants reflète également les difficultés créées par l'exploitation d'un modèle global dans un court espace de temps, associée à des conséquences inattendues du modèle » (OCDE, 2009. P.1). Cette recherche vient dans un moment où la profession enseignante souffre de profonds changements, en particulier dans les règles d'accès et de progression. Le nouveau modèle d'évaluation du rendement des enseignants, 2/2008 du 10 Janvier, a un impact plus important sur la carrière, car elle empêche la progression des enseignants, presque automatiquement. Une évaluation avec une charge négative, car elle dicte qui ne parviendra pas à progresser rapidement (et non pas avec une charge positive, en indiquant qui progresse rapidement.) Avec ce scénario décrit, il faudra une exemption absolue et rigoureuse dans l'évaluation des performances, sans lequel il produira son discrédit global. La mise en oeuvre du nouveau modèle d'évaluation s'avère être un nouveau développement "critique". Ce travail vise comprendre les difficultés dans l'application du nouveau modèle d'évaluation. Il commence par une construction conceptuelle de ce que c’est la formation professionnelle, ce qu'on entend par développement professionnel, la compétence professionnelle et de l'efficacité pédagogique. Traite des questions inhérentes à l’évaluation formative et sommative, on trouve quelques exemples de modèles d'évaluation des performances réalisées aux États-Unis en ce qui concerne les résultats des élèves. La nature exploratoire de cette étude a légitimé l'utilisation de leurs joueurs clés, les enseignants, en cherchant à identifier leurs points de vue et leurs préoccupations. Cette étude de cas décrit le processus de mise en oeuvre du nouveau "modèle" d'évaluation des performances dans une école de 2e et 3e cycles de l'enseignement de base, intégrés dans une zone de grande affluence de population multiculturelle au cours des deux premières années, la durée du premier cycle du processus d'évaluation. Pour élucider les difficultés et les réactions l'enquête montre les problèmes, les tensions et les contradictions de l'évaluation des performances, mis en place sous des échanges de tirs entre la rhétorique de l'amélioration de la qualité et un dispositif de formation d’amélioration de la performance axé sur la gestion entre les naïfs soi-disant auto-critique et de la stratégie d'auto-présentation. Un jeu de récompenses et de sanctions en fonction de l'évaluation et une évaluation par les critères d'évaluation et les normes qui restent cachés au dessous d’un brouillard qui entoure l'ensemble du processus, marquée par des avancées successives et des reculs.

Texte intégralDado que as organizações se regem por processos de negócio, é emergente a necessidade de o desenvolvimento do sistema de informação de uma organização seja direccionado para suportar esses processos. Durante um processo de desenvolvimento de sistemas de informação são conhecidas várias abordagens e metodologias com o objectivo de este seja obtido com cada vez maior acréscimo de qualidade. Essa qualidade deve-se reflectir na definição dos processos do sistema de informação e deve requerer uma metodologia que possua tarefas bem definidas e automatizadas. Uma metodologia possível, a Business Implementation Methodology (BIM), propõe transformações dos processos de negócio de forma automatizada para que a implementação dos processos em software consuma menor esforço e menores custos. As quatro fases da metodologia são percorridas desde a definição inicial dos processos de negócio até ao sistema de informação final. O que distingue nesta fase das outras metodologias é a proposta de utilizar modelos de referência de processos. Dado o contexto, sugere-se a utilização de linguagens de modelação de processos para representação gráfica dos processos de negócio. Para obtenção do sistema de informação na última fase da metodologia seguida, é proposta a utilização do Model-Driven Architecture (MDA). A transformação de um modelo de processos de negócio que seja um Platform Independent Model (PIM) para um modelo que seja um Platform Specific Model (PSM) permitirá a obtenção da implementação do modelo de processos em software. O resultado da transformação será um modelo composto pelo processo de negócio em BPEL e pela devida integração de aplicações realizadas através do uso de um Enterprise Service Bus (ESB).
Due the fact that organisations rule their business by business processes, it is emerging the need that development of the information system should be oriented to support those processes. During the process of an information system development many approaches are known so it can be achieved with an increase of quality. This quality must be reflected in the definition of the information system’s business processes and it requires a methodology that has well defined and automated tasks. A possible methodology, the Business Implementation Methodology (BIM), proposes transformations of business processes in an automated way so software implementation of the processes are less effort consuming. The four methodology phases are executed since the initial definition of the business process to the final information system. What distinguishes this methodology from other business implementation methodologies in these initial phases is the use of process reference models proposal. In the context, it is suggested the use of business process modelling languages for visual representation of business processes. For obtaining the information system in the last phase of the methodology, it is proposed the use of OMG’s Model-Driven Architecture (MDA). The transformation of a process framework that is a Platform Independent Model (PIM) to a Platform Specific Model (PSM) will allow obtaining software implementation. The result of the transformation will be a model composed by the business process in BPEL and the integration of applications through the use of an Enterprise Service Bus (ESB).
