Повний текст джерелаPursuant to Common Article 1 to the four Geneva Conventions of 1949, the State parties have the obligation to respect and to ensure respect for International Humanitarian Law (IHL). In this context, the objective of this thesis is to analyze whether the European Union (EU) and two of its Member States – France and Spain – have enforced their obligation to ensure respect for IHL. It seeks to scrutinize how two juris corpuses, namely IHL and EU law, which used to follow separate paths, appeared to converge and be interlinked. This thesis takes the view that the enforcement of IHL must must be analyzed from a multilevel perspective. While IHL rely on national law to be truly effective, the process of European integration makes it imperative to add the supranational level: the EU. This configuration generates a virtuous circle of compliance whereby the legal authority of Common Article 1 is reinforced, thus leading to the improved enforcement of IHL. In turn, the EU projects its values on the international scene and is ‘confortée’ as a leader in human rights. Likewise, the EU constitutes an additional level of guarantee and action for its Member States in the enforcement of their obligation arising under IHL. It is argued that the EU has established itself as an essential actor of IHL on the international scene. The EU – a self-proclaimed leader in human rights matters – and its Member States are not only bound by Common Article 1, but they also have accepted their mandate to effectively enforce it on the international scene.

Повний текст джерелаBackground: Current understanding of tuberculosis (TB) genotype clustering in the US is based on individual risk factors. This study sought to identify whether area-based socioeconomic status (SES) was associated with genotypic clustering among culture-confirmed TB cases. Methods: A retrospective cohort analysis was performed on data collected on persons with incident TB in King County, Washington, 2004–2008. Multilevel models were used to identify the relationship between area-level SES at the block group level and clustering utilizing a socioeconomic position index (SEP). Results: Of 519 patients with a known genotyping result and block group, 212 (41%) of isolates clustered genotypically. Analyses suggested an association between lower area-based SES and increased recent TB transmission, particularly among US-born populations. Models in which community characteristics were measured at the block group level demonstrated that lower area-based SEP was positively associated with genotypic clustering after controlling for individual covariates. However, the trend in higher clustering odds with lower SEP index quartile diminished when additional block-group covariates. Conclusions: Results stress the need for TB control interventions that take area-based measures into account, with particular focus on poor neighborhoods. Interventions based on area-based characteristics, such as improving case finding strategies, utilizing location-based screening and addressing social inequalities, could reduce recent rates of transmission.

Повний текст джерелаThe expression of « demotic pluralism » is used to designate the coexistence of different people in a multilevel system. Contrary to the traditional monist definition of the French people, this thesis aims to demonstrate the coexistence of several demoi in French constitutional law. In order to do so, the demonstration is structured into three parts. First, we explore the pluralist definition of demos in multilevel systems: the federal (India, Germany,United States, Switzerland) and the regional type (Spain, United Kingdom). Then, we submita theory of multilevel demotic pluralism, which allows to describe and analyse the coexistence of a compound people and component people in a multilevel system. Finally, we apply this theoretical framework to the French legal system and to the European Union

Повний текст джерелаEnergy systems based on fossil fuel have demonstrated their abilities to permit economic development. However, with the fast exhaustion of this energy source, the expansion of the world energy demand and concerns over global warming, new energy systems dependent on renewable and other sustainable energy are gaining more interests. It is a fact that future development in the energy sector is founded on the utilisation of renewable and sustainable energy sources. These energy sources can enable the world to meet the double targets of diminishing greenhouse gas emissions and ensuring reliable and cost-effective energy supply. Fuel cells are one of the advanced clean energy technologies to substitute power generation systems based on fossil fuel. They are viewed as reliable and efficient technologies to operate either tied or non-tied to the grid to power applications ranging from domestic, commercial to industrial. Multiple fuel cell stacks can be associated in series and parallel to obtain a fuel cell system with high power up to megawatts. The connection of megawatts fuel cell systems to a utility grid requires that the power condition unit serving as the interface between the fuel cell plant and the grid operates accordingly. Different power conditioning unit topologies can be adopted, this study considers a multilevel inverter. Multilevel inverters are getting more popularity and attractiveness as compared to conventional inverters in high voltage and high-power applications. These inverters are suitable for harmonic mitigation in high-power applications whereby switching devices are unable to function at high switching frequencies. For a given application, the choice of appropriate multilevel topology and its control scheme are not defined and depend on various engineering compromises, however, the most developed multilevel inverter topologies include the Diode Clamped, the Flying Capacitor and the Cascade Full Bridge inverters. On the other hand, a multilevel inverter can be either a three or a five, or a nine level, however, this research focuses on the three-level diode clamped inverters. The aim of this thesis is to model and control a three-level diode clamped inverter for the grid connection of a megawatt fuel cell stack. Besides the grid, the system consists of a 1.54 MW operating at 1400 V DC proton exchange membrane fuel cell stack, a 1.26 MW three-level diode clamped inverter with a nominal voltage of 600 V and an LCL filter which is designed to reduce harmonics and meet the standards such as IEEE 519 and IEC 61000-3-6. The inverter control scheme comprises voltage and current regulators to provide a good power factor and satisfy synchronisation requirements with the grid. The frequency and phase are synchronised with those of the grid through a phase locked loop. The modelling and simulation are performed using Matlab/Simulink. The results show good performance of the developed system with a low total harmonic distortion of about 0.35% for the voltage and 0.19% for the current.

Повний текст джерелаENGLISH ABSTRACT: This thesis investigates the viability of constructing a solid-state transformer (SST) with a series-input, parallel-output connection of full-bridge, three-level ying-capacitor converters. It focusses on the active recti er front-end of the SST which is used to control the input current to be sinusoidal and in-phase with the sinusoidal input voltage. A stack of two converters are built and tested. The input current, as well as the ying capacitor voltages of the two active recti ers in the stack, are actively controlled by a nite-state model-based predictive (FS-MPC) controller. The use of multiple ying-capacitor converters poses a problem when using FS-MPC because of the large number of possible switching states to include in the prediction equations. Three FS-MPC control algorithms are proposed to attempt to overcome the problem associated with the large number of switching states. They are implemented on an FPGA digital controller. The algorithms are compared on the bases of voltage and current errors, as well as their responses to disturbances that are introduced into the system. The simulation and experimental results that are presented shows that by interleaving the control actions for the two converters, one can obtain fast and robust responses of the controlled variables. The viability of extending the interleaving control algorithm beyond two converters is also motivated.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die moontlikheid van volbrug, drievlak vlieënde-kapasitoromsetters wat gebruik word om 'n serie-intree, parallel-uittree drywingselektroniese transformator (DET) te bou. Dit fokus op die aktiewe gelykrigter van die DET wat gebruik word om die intreestroom te beheer om sinusvormig en in fase met die sinusvormige intreespanning te wees. 'n Stapel van twee omsetters word gebou en getoets. Die intreestroom, sowel as die vlieënde kapasitorspannings van die twee aktiewe gelykrigters in die stapel, word aktief beheer met behulp van 'n eindige-toestand, model-gebaseerde voorspellende beheerder (ET-MVB). Die gebruik van veelvuldige vlieënde-kapasitoromsetters bemoeilik die implementering van 'n ET-MVB-beheerder as gevolg van die groot aantal skakeltoestande wat in die voorspellende vergelykings in ag geneem moet word. Drie ET-MVB-algoritmes word voorgestel om te poog om die probleme, wat met die groot aantal skakeltoestande geassosieer word, te oorkom. Die algoritmes word in 'n FPGA digitale verwerker geïmplementeer. Die algoritmes word vergelyk op grond van hul stroom- en spanningsfoute, asook hul reaksie op steurings wat op die stelsel ingevoer word. Die simulasie en praktiese resultate toon dat, deur die beheeraksies vir die twee omsetters te laat oorvleuel, die gedrag van die beheerde veranderlikes vinniger en meer robuust is. Die moontlikheid om die oorvleuelende beheeraksies uit te brei tot meer as twee omsetters word ook gemotiveer.

Повний текст джерелаO baixo peso ao nascer (BPN) é um importante problema de saúde pública em todo o mundo, embora mais acentuado nas áreas menos desenvolvidas. Crianças com BPN apresentam um maior risco de morbidade e mortalidade durante o primeiro ano de vida e, aquelas que sobrevivem ficam mais expostas ao risco de desenvolver sequelas. No presente estudo, fatores individuais e contextuais, associados com o baixo peso, foram identificados com base em informações sobre nascido-vivos do estado do Rio de Janeiro, no período 2000-2005. Um modelo logístico multinível com dois níveis, municípios e mães, foi utilizado. Os resultados mostraram uma tendência de queda da proporção de baixo peso no Estado. Em média, a cada ano, a chance de uma criança nascer com baixo peso declinou aproximadamente 2%. O PIB per capita também se mostrou associado com o baixo peso ao nascer. Aumentos de R$ 5000,00 no PIB anual reduziu a chance de uma criança nascer com baixo peso em 2%. Mulheres adolescentes ou com 40 anos ou mais, assim como as solteiras e viúvas foram mais propensas a ter um filho com baixo peso. A chance de ter um filho com baixo peso diminuiu com o aumento da escolaridade da mãe, mas com pequena variação nas categorias acima de três anos de estudo. O tipo de hospital apareceu como forte preditor do BPN, com chance mais elevada de ter um filho com BPN entre mulheres cujo parto foi realizado em hospital público. Destaque deve ser dado para o efeito que o número de consultas pré-natal exerceu sobre o BPN. A chance de uma criança, cuja mãe realizou pelo menos sete consultas durante o pré-natal, nascer com baixo peso foi 44% menor do que a observada entre mães que realizaram até três consultas. A variância do componente aleatório estimada pelo modelo multinível indica que há uma variação significativa do baixo peso no nível municipal não-explicada pelas variáveis incluídas na análise. Estudos futuros devem procurar identificar esses fatores. Políticas públicas devem ser implementadas, focando não apenas na redução da prevalência do baixo peso, mas também no monitoramento dessas crianças, de modo a reduzir a chance de uma criança apresentar sequelas ou diminuir os danos por elas causados
Low birth weight (LBW) is a major public health problem worldwide, although more pronounced in less developed areas. LBW children are at greater risk of morbidity and mortality during the first year of life, and those who survive are most at risk of developing sequela. In this study, individual and contextual factors associated with low birth weight were identified based on information on births in the state of Rio de Janeiro from 2000 to 2005. A multilevel logistic model with two levels, municipalities and mothers, was used. The results showed a downward trend in the proportion of low birth weight in the state. On average, each year, the chance of a low birth weight declined approximately 2%. GNP per capita was also associated with low birth weight. Increases of R$ 5,000.00 in annual GNP reduced the chance of a low birth weight by 2%. Adolescents or women aged 40 years or more, as well as single women and widows, were more likely to have a child with low birth weight. The chance of having a child with low birth weight decreased as mother's education increased, but with little variation in the categories above three years of study. The type of hospital emerged as a strong predictor of low birth weight, with increased probability of having a child with LBW among women whose deliveries were performed in public hospitals. Emphasis must be given to the effect that the number of pre-natal consultations exerted on LBW. The chance of a child whose mother had at least seven visits during prenatal care, low birth weight was 44% lower than that observed among mothers who had up to three visits. The variance of the random component estimated by the multilevel model indicates that there is significant variation in the low-weight at the municipal level, not explained by variables included in the analysis. Future studies should seek to identify these factors. Public policies should be implemented, focusing not only on reducing the prevalence of low birth weight, but also on monitoring these children, in order to reduce the chance that a child has sequelae or decrease the damage they caused

Повний текст джерелаBackground: Studies have suggested that subjective measures of oral health can be influenced by both individual and contextual factors. However, studies assessing the interaction of individual and contextual determinants of subjective measures of oral health are scarce. Objective: This study assessed the effect of individual and contextual variables on the oral health-related quality of life in preschool children (COHRQoL). Methods: We followed a cross-sectional design, with a multistage random sample of 478 preschool aged 1-5 years old, representative of Santa Maria, a southern city in Brazil. Caregivers completed a questionnaire validated in COHRQoL (ECOHIS) and answered questions about the socioeconomic status and social capital. The dental examination provided information on the prevalence of dental caries, dental trauma and occlusion of preschoolers. Data were analyzed using multilevel linear regression model. Results: The mean ECOHIS was 1.8 (SD:3.9) and the functional domain of the session was the most affected children (mean = 0.5, SD =1.4). The multivariable multilevel model identified dental caries, dental trauma, anterior open bite, low socioeconomic status and low feature of social capital as individuals determinants of poor self-perception and quality of life. At a contextual level, children who lived in areas without community cultural centers were more likely to have impacts on the quality of life. Conclusion: The areas with unfavorable social conditions and poor socioeconomic status and poor dental status have a negative impact on COHRQoL.
Justificativa: Estudos têm sugerido que as medidas subjetivas de saúde bucal podem ser influenciadas tanto por determinantes de ordem individual como por fatores relacionados ao contexto em que vivem os indivíduos. Entretanto, a utilização de abordagem multinível para refletir a complexa interação de tais fatores na população infantil ainda é escassa. Objetivo: Este estudo avaliou o efeito de variáveis individuais e contextuais na qualidade de vida relacionada à saúde bucal em pré-escolares utilizando análise multinível. Material e Métodos: O estudo apresentou desenho transversal, com uma amostra de 478 pré-escolares com idade entre 1-5 anos, moradores de Santa Maria-RS, Brasil. Dados a respeito da auto-percepção e qualidade de vida relacionada a saúde bucal foram coletados através do Early childhood Oral Health Impact Scale (ECOHIS). Informações a respeito de status socioeconômico foram obtidas mediante questionário semi-estruturado respondido pelos pais. O exame odontológico forneceu informações sobre a prevalência de cárie dental, trauma dental e oclusão de pré-escolares. Os dados foram analisados utilizando o modelo de regressão linear multinível. Resultados: A média do ECOHIS foi 1,8 (dp: 3,9) e o domínio funcional na sessão criança foi o mais afetado (média = 0,5; dp:1,4). A análise multinível demonstrou que as crianças com cárie dental, trauma dental, mordida aberta anterior, com renda familiar baixa e com pior capital social apresentaram maiores scores de ECOHIS. Após ajuste por variáveis contextuais, crianças que viviam em áreas sem centros comunitários culturais apresentaram maior impacto na qualidade de vida. Conclusão: Condições contextuais desfavoráveis e pior padrão de saúde bucal influenciam negativamente o modo como os pais relatam a saúde bucal das crianças.

Повний текст джерелаThis work aims to present thetheoretical study, the numerical analysis and theexperimental validation of a power electronicsconverter topology based on an interleavedmodular multilevel converter with mediumfrequencytransformer. The architecture issuitable for the AC-DC stage in solid-statetransformer applications for the connectionbetween a medium-voltage AC grid and a lowvoltageDC grid. The interleaving reduces theswitch conduction losses. The 10 kHz mediumfrequencytransformer provides galvanicisolation and connects the interleaved modularmultilevel converter to a full-bridge converter.From the converter structure, the principle ofoperation, the modeling, the modulationtechnique, and the control scheme are discussed.One feature of the converter is the simultaneousgeneration of the low-frequency grid voltageand the medium-frequency transformer primaryvoltage. The capacitor voltage balancing and thecirculating currents minimization are combinedtogether in a single algorithm. The controlsystem regulates the AC current and the DC busvoltage, on the high-voltage side, and the DCvoltage and power flow, on the low voltage side.The experimental validation of the converter ismade with a scaled-down single-phase 720 Wprototype. The results demonstrate the controlsystem stability in steady-state and dynamic(load step, power flow inversion) operations

Повний текст джерелаThe thesis at hand explored effects of the language-related and ethnic makeup of classrooms on several achievement outcomes as well as psychosocial outcomes in three research articles. The first article investigated effects of socioeconomic and language minority classroom composition on ninth graders’ reading achievement across two measurement points and explored the mediating role of instructional quality. The proportion of minority students had no effect on achievement after controlling for the socioeconomic composition. The results suggest that the effect of the socioeconomic composition on achievement may be mediated partially by the teacher’s focus on language during instruction. The second article focused on effects of the proportion of language minority students on the development of ninth graders’ motivation and the mediating role of a student-oriented climate. The analyses revealed that minority students were increasingly motivated in classrooms with a higher proportion of minority students. The compositional effect was not mediated by the instructional climate. The third article explored various measures of the ethnic makeup of classrooms and their relationship with student outcomes. The proportion of minority students and measures of diversity were compared in their prediction of fourth graders’ achievement in math and reading as well as the feeling of belonging with one’s peers. The proportion of minority students showed stronger negative effects on student outcomes than the diversity measures. Including diversity measures and the proportion of minority students, the diversity effects mostly lost their significance. However, students showed slightly higher levels of math achievement in more diverse classrooms. The various measures of diversity led to similar results. The findings add to the evidence indicating that the classroom learning environment affects students’ academic development and contributes to ethnic disparities in the education system.

Повний текст джерелаThe internal regionalisation and European integration place compound Member States in a special relationship with the European Union. These two processes confront national authorities with obligations from different, and sometimes seemingly contradictory or irreconcilable, sources. This confrontation has led to a process of adaptation of the compound States to their status as members of the European Union. Not without tensions, their adaptation is proving to be sufficiently successful so that it is no longer possible to describe their participation in the European Union without taking into account the role of their constituent communities. At the same time, European Union law has gradually taken account of the composite form of these Member States. Regional self-government is now part of the national identity, the respect of which is an obligation for the Union. However, there is still room for improvement in adapting it by taking better account of the regional dimension of the composite Member States. The articulation of relations between the European Union and the States in question reveals a particular structuring which can be described and understood through an emerging legal figure: the composite State which is a member of the European Union

Повний текст джерелаThis thesis deals with the modeling and control of MMCs in the context of MTDC. The first objective is to obtain an MMC model in dq frame which can reproduce accurately the AC- and DC- interactions, while representing at the same time the internal dynamics which may interact with the rest of the system. This model is suitable to be linearized and to study its stability, among other linear techniques. Then, based on the developed dq model, different control strategies are developed based on the state-of-the-art on MMC controllers. Since the order of the system may be a limiting factor for studying MTDC grids with many MMCs, different reduced-order models are presented and compared with the detailed dq model. Finally, the developed MMC models with different controllers are used for the MTDC studies. The impact of the chosen controllers of each MMC is evaluated, highlighting the potential issues that may occur in multivendor schemes

Повний текст джерелаThe international legal system perceives a sub-state collectivity as a sovereign State's organ. This classical logic of assimilation, led by a statist perception of international relations, conducts the operations of identification of a commitment due to a juridical act, attribution of a wrongful act and acceptance of standing. In this context, a sub-state collectivity is not considered as a juridical person, subject to the particular situation of federated collectivities. Originally international, European Union's (E.U.) and Council of Europe's legal systems retain a measure of this heritage. However, the incorporation of sub-state collectivities in this regional legal system, admittedly still dominated by States, raises them gradually to the rank of singular actresses. The empowerment of both European legal systems from these classical international mechanisms and the realization of the principle of immediacy bring to reconsider the relevance of a systematic assimilation of the sub-state collectivities as insignificant parts of State and take account of their own juridical personality, such as established by domestic law. This new logic of personification, which develops vertical (i.e. relations between European and domestic legal systems) and horizontal dimensions (i.e. relations between domestic legal systems) is still imperfect. When they're not considered as State's organs, sub-state collectivities are sometimes perceived as individuals, who try to satisfy their own interests without any reference to general interest

Повний текст джерелаThis work deals with limit cycle control for one particular class of hybrid dynamical systems (HDS): The cyclic switched systems. The HDS were born because the traditional dynamical models were not able to describe complex behaviors and most of all, behaviors with discontinuities. From an application point of view, one important class of HDS depicts a cyclic behavior in steady state. The main characteristic of these systems is that the operation point cannot be maintained: It does not exist a control that maintains the system on a desired operation point. However, this point can be obtained in average by turning into its neighborhood. Thus, a cycle is produced by switching among the system modes. A switched control law must satisfy stability and dynamic performance. Moreover, criteria related to the waveform must be verified. Nowadays, few methods take into account the cyclic behavior of the system. In this research, some generic methods are studied. They show good performance for controlling the cyclic switched systems. The proposed algorithms can be implemented in real-time. The approaches are based on an affine non-linear model of the system whose control explicitly appears. Two control methods are considered: i) A predictive control, ii) An optimal control. Since the predictive control is a good choice for tracking, it will be able to maintain the system in a cycle. The optimal control yields solutions that can be applied to the transients. Some experiments with both control methods applied to the power converters are shown. These tests were carried out not only in our laboratory (CRAN), but also in other laboratories as part of the HYCON excellence network
