Depuis plusieurs années les chiffres de l'insécurité routière montrent la nécessité de développer un outil technologique qui vise à connaitre le comportement de véhicules deux roues motorisés (2RM) afin d'améliorer leursécurité. De cette problématique découle nos travaux de recherche qui s'inscrivent dans le cadre de projet METRAMOTO (MEsure du TRAfic des deux-roues MOTOrisés pour la sécurité routière et l'évaluation des risques)L’objectif principal visé concerne la modélisation, le dimensionnement et l'optimisation d'un capteur hybride constitué d'une part de boucles électromagnétiques et d'autre part de capteurs de chocs piézo-électriques. L’idée consiste à utiliser les boucles électromagnétiques pour discriminer la présence des 2RM de celle des autresvéhicules, associées à des segments piézo-électriques pour détecter le choc produit par le passage des roues desdifférents véhicules, le tout associé à un algorithme de gestion et de traitement de données. Aujourd'hui redimensionnement des systèmes de détection à base de boucles électromagnétiques ou de câble piézo-électriquese fait de manière expérimentale sur des sites contrôlés en utilisant plusieurs types de véhicules. Cette technique gourmande en temps nécessite une série importante d'essais couteux et dangereux. La présente étude a pour butde modéliser les différentes interactions entre le capteur hybride étudié et les véhicules en vue de son dimensionnement. Des modèles électromagnétiques et électromécaniques sont développés pour décrire les différentes interactions se produisant entre les boucles électromagnétiques d'une part, les boucles électromagnétiques et les véhicules d'autre part ainsi que celles des roues de véhicules et le câble piézoélectrique.Sur la base de ces modèles établis, une démarche générale est élaborée conduisant au dimensionnement du capteur hybride pour une route donnée. Nous nous sommes également intéressés au traitement des données issues du capteur hybride pour lesquelles nous proposons une approche d'identification des différentes catégories de véhicules dont les 2RM. Deux configurations de capteurs pour deux routes différentes sont alors proposées.Elles sont associées à des algorithmes de traitement de données permettant l'acquisition des signaux de boucles et de câbles, la distinction des différents types de véhicules, l'estimation de la position des véhicules sur la chaussée ainsi que la mesure de la vitesse de véhicules. / For several years the road safety numbers show the need to develop a technological tool that aims to know thepowered two wheelers vehicles behavior (2PW) to improve their security. From this problematic arise our researchworks that come under the project METRAMOTO (Powered two wheelers traffic measurement for road safety andrisks assessment). The main objective is modeling, sizing and optimization of an hybrid sensor consisted ofelectromagnetic loops and piezoelectric shock sensors. The idea is to use electromagnetic loops to discriminate the2PW presence from the other vehicles, combined with piezoelectric segments to detect the shocks produced by thevehicles wheels passage, all associated with a management algorithm and data processing. Today the sizing of thedetection systems based on electromagnetic loops or piezoelectric cables is done experimentally on controlled sitesusing several vehicles types. This technique requires significant test series which are costly and dangerous. Thisstudy aims to modeling the different interactions between the studied sensor and vehicles in order to its sizing.Electromagnetic and electromechanical models are developed to describe the different interactions that take placebetween electromagnetic loops on the one hand, between electromagnetic loops and vehicles on the other handand those between vehicle wheels and piezoelectric cable. On the basis of established models, a general approachis elaborated driving to sizing the hybrid sensor for any given road. We are also interested to the data processingcoming from the hybrid sensor for which we propose an approach to identifying the different vehicle categoriesincluding the 2PW. Two sensor configurations for two different roads are then proposed. They are associated atdata processing algorithms allowing the acquisition of loops and cables signals, the distinction between the differentvehicles classes, the estimation of the vehicles positions on the road and the measuring of their speed.

An improvement of the Brazilian fiscal federalism, with greater resources decentralization and the implementation of high-powered rules for the federative transfers may be an important tool in the improvement of our social conditions. To do so, this thesis was divided into four distinct parts. The first chapter discusses the oil revenues impacts on unicipalities’ public finance. The legal changes that occurred in Brazil in the nineties in the oil and gas sector led to increasing royalties transfers to Brazilians states and municipalities. The annedoctical evidence that this transfers are not been used properly - in a way that would increment the local welfare - have originated a important discussion about these distribution rules. This paper tries to identify this revenues impacts over others municipalities’ fiscal variables. It seems that this did not impact the others sources of municipalities revenue. Unhappily, some of the resources (which distribution is either more or less concentrated) led the municipalities to increase their current expenditures and diminishes their investments efforts. At the same time, they are not spending this extra money in a way that would increment the local welfare. On the other hand, the resources which distribution is between these two limits has the opposite effect. The second chapter discusses the impact of oil revenues on the proficiency of fourth grade students of primary public schools. The oil revenues - bundled or not - were not statistically significant in explaining the observed student performance in Portuguese and mathematics. This result, however, must be analyzed with caution, since it is not trivial to identify how (and when) these effects would be generated. However, different sources of municipal revenue would impact differently the students’ proficiency scores, explaining why we need to better understand these differences to design more efficient constitutional transfer mechanisms to the municipalities. In the third chapter, we study the impacts of municipal emancipation occurred in the 90s on the well-being of local populations. More than a thousand of new municipalities were created at the nineties in Brazil, due the new Federal Constitution of 1988. There is anecdotic evidence that this was a pretty harmful process for the Brazilian welfare, but there were no systematic attempt to valuate it properly. This paper tries to do so using data from Minas Gerais municipalities which number has grown from 723 to 853 ones in that decade. The results suggest that this process strongly improved the welfare of the local population. This implies that local political markets are efficient and it should be allowed for any district to emancipate from its former municipalities, if their population wishes to do so. Finally, in the fourth chapter we analyze the impact of law (implemented in Minas Gerais) who sought to increase the incentives pro-efficiency of municipal governments. In order to improve the welfare of its citizens, the state government of Minas Gerais (Brazil) has imposed, at 1995, the state law 12.040, known as Robin Hood law. It stated that 25% of the revenue transferred to the municipalities should be allocated through observable results achieved in education, health, environment among others. In other words, this law established a high power contract between the state government and the municipalities, which is not very usual. This study shows that this law had a significant impact on the municipalities’ education and health. But it’s necessary to redesign these transfers’ rules, in order to improve its power and its results. These results shows that the use of high powered rules in federative transfers could be a strong mechanism in order to improve the population welfare. / Esta tese busca discutir problemas relacionados às finanças públicas municipais no país. Um aprimoramento de nosso federalismo fiscal, com maior descentralização de recursos e implementação de regras de transferências federativas com maiores incentivos pró-eficiência – aumentando os incentivos pró-obtenção de melhores resultados sociais por parte das unidades subfederadas – pode se revelar instrumento importante na melhoria de nossas condições sociais. Para isto, dividiu-se esta tese em quatro partes distintas. No primeiro capítulo, discutem-se os impactos das receitas petrolíferas sobre as finanças públicas municipais. As mudanças legais ocorridas no país na década de noventa do último século - relativas ao setor petrolífero - levaram a crescente (e concentrada) transferência de recursos do setor para os estados e municípios brasileiros. A forte sensação que estes estariam sendo desperdiçados de alguma forma vem suscitando discussões sobre a necessidade de se reformular sua distribuição. As recentes descobertas de megacampos petrolíferos no pré-sal do litoral brasileiro somente intensificaram este processo. Buscou-se identificar os efeitos destas transferências sobre as variáveis fiscais municipais no país. Detectou-se que não ocorreu substituição tributária, ou seja, estes recursos não diminuíram o esforço arrecadatório dos municípios. Em compensação, tanto os recursos cuja distribuição é bem mais concentrada (referentes aos royalties excedentes) quanto aqueles mais bem-distribuídos (referentes aos royalties originais) levaram as prefeituras a aumentar seus gastos correntes (piorando sua composição do ponto de vista social) e diminuir seus investimentos. O contrário parece ocorrer com os recursos cuja distribuição se dá de forma intermediária (os royalties referentes às participações especiais). No segundo capítulo, discute-se o impacto das receitas petrolíferas sobre a proficiência dos alunos até a quarta série primária das escolas públicas municipais. As receitas petrolíferas – agregadas ou não – não se mostraram estatisticamente significativas na explicação do desempenho observado pelos alunos da quarta série primária das escolas municipais em português ou matemática. Este resultado, entretanto, deve ser olhado com cautela, uma vez que não é trivial identificar como (e o tempo necessário) estes efeitos seriam gerados. Entretanto, diferentes fontes de receitas municipais impactariam de forma diferenciada as proficiências observadas nos testes de português e matemática, explicitando a necessidade de se entender melhor estas diferenças para se desenhar mecanismo mais eficiente de repasse de recursos constitucionais aos municípios. No terceiro capítulo, estudam-se os impactos das emancipações municipais ocorridas na década de 90 sobre o bem-estar das populações locais. Devido à Constituição Federal de 1988, o número de municípios no Brasil multiplicou-se fortemente na década de 90 do último século. Mais de mil municípios foram criados em todo o país, fazendo seu número ultrapassar a casa dos 5.500. Este processo tem sido interpretado de forma bastante negativa. Baseado em evidências anedóticas, se pressupõe que os atores políticos locais o utilizaram para se apropriar de maior parcela dos recursos transferidos de outros níveis governamentais. Entretanto, nenhum esforço mais sistemático foi realizado buscando calcular, de maneira efetiva, os resultados sociais líquidos deste processo. É isto que se busca fazer aqui, utilizando dados sobre os municípios mineiros - cujo número passa de 723 em 1991 para 853 em 2000. Foram detectados impactos positivos relacionados a diversas variáveis educacionais e de saúde. Ao mesmo tempo, o contrário ocorreu com os indicadores de pobreza e indigência. Este resultado mostra que o movimento observado de emancipação municipal talvez tenha sido bastante benéfico, sinalizando para a existência de mercados políticos eficientes nestas localidades, o que indicaria a necessidade de se manter uma maior autonomia local relativa a processos de emancipação de distritos. Por fim, no quarto capítulo, analisam-se os impactos de lei (implementada em Minas Gerais) que buscou aumentar os incentivos pró-eficiência das prefeituras municipais a partir das transferências federativas. Buscando melhorar as condições de vida dos municípios mineiros, o governo estadual mineiro instituiu, em 1995, a lei 12.040, conhecida como Lei Robin Hood. Esta permitia que 25% dos recursos de ICMS a serem distribuídos aos municípios mineiros se dessem sobre resultados observáveis em diversas áreas tais como saúde, educação, conservação ecológica, entre outras. Ou seja, esta instituía, em relação a estas transferências, um contrato de alto poder com os municípios relacionados às políticas públicas implementadas. O estudo destas transferências (relativas à educação e saúde) mostrou resultados dúbios. Resultados positivos relativos à educação e à saúde parecem ocorrer em todo o estado, mas os incentivos dados poderiam ser bem maiores - faz-se necessário um refinamento das regras da partilha destas transferências. Dada a relativa escassez deste tipo de contrato em transferências federativas, seja no Brasil, seja no restante do mundo, este resultado aponta a necessidade de utilização de instrumentos de maior poder nas relações federativas, buscando incrementar as condições de vida locais.

L'objectif de cette thèse est de développer des outils d'analyse de données recueillies sur les deux roues motorisés (2RMs). Dans ce cadre, des expérimentations sont menées sur des motos instrumentés dans un contexte de conduite réelle incluant à la fois des conduites normales dites naturelles et des conduites à risques (presque chute et chute). Dans la première partie de la thèse, des méthodes d'apprentissage supervisé ont été utilisées pour la classification de situations de conduite d'un 2RM. Les approches développées dans ce contexte ont montré l'intérêt de prendre en compte l'aspect temporel des données dans la conduite d'un 2RM. A cet effet, nous avons montré l'efficacité des modèles de Markov cachés. La seconde partie de cette thèse porte sur le développement d'outils de détection et de classification hors ligne des évènements critiques de conduite, ainsi que, la détection en ligne des situations de chute d'un 2RM. L'approche proposée pour la détection hors ligne des évènements critiques de conduite repose sur l'utilisation d'un modèle de mélange de densités gaussiennes à proportions logistiques. Ce modèle sert à la segmentation non supervisée des séquences de conduite. Des caractéristiques extraites du paramètre du modèle de mélange sont utilisées comme entrées d'un classifieur pour classifier les évènements critiques. Pour la détection en ligne de chute, une méthode simple de détection séquentielle d'anomalies basée sur la carte de contrôle MCUSUM a été proposée. Les résultats obtenus sur une base de données réelle ont permis de montrer l'efficacité des méthodologies proposées à la fois pour la classification de situations de conduite et à la détection des évènements critiques de conduite / This thesis aims to develop framework tools for analyzing and understanding the riding of Powered Two Wheelers (PTW). Experiments are conducted using instrumented PTW in real context including both normal (naturalistic) riding behaviors and critical riding behaviors (near fall and fall). The two objectives of this thesis are the riding patterns classification and critical riding events detection. In the first part of this thesis, a machine-learning framework is used for riding pattern recognition problem. Therefore, this problem is formulated as a classification task to identify the class of riding patterns. The approaches developed in this context have shown the interest to take into account the temporal aspect of the data in PTW riding. Moreover, we have shown the effectiveness of hidden Markov models for such problem. The second part of this thesis focuses on the development of the off-line detection and classification of critical riding events tools and the on-line fall detection. The problem of detection and classification of critical riding events has been performed towards two steps: (1) the segmentation step, where the multidimensional time of data were modeled and segmented by using a mixture model with quadratic logistic proportions; (2) the classification step, which consists in using a pattern recognition algorithm in order to assign each event by its extracted features to one of the three classes namely Fall, near Fall and Naturalistic riding. Regarding the fall detection problem, it is formulated as a sequential anomaly detection problem. The Multivariate CUmulative SUM (MCUSUM) control chart was applied on the data collected from sensors mounted on the motorcycle. The obtained results on a real database have shown the effectiveness of the proposed methodology for both riding pattern recognition and critical riding events detection problems

I en tid kännetecknat av en strävan efter ett mer hållbart samhälle, med utformade långsiktiga klimatmål för förnyelsebara energikällor och minskade utsläpp, arbetar fordonsutvecklare med att ta fram alternativ till förbränningsmotorer. För att nå satta klimatmål och samtidigt förbättra arbetsmiljön med minskat buller anses en elektrisk drivlina som ett troligt alternativ. För tunga fordon såsom lastbilar som ofta utrustas med tillsatsutrustning som kranar, tippbara flak eller cementroterare är beroende av ett kraftuttag för att driva hydraulpumpar och generatorer. Vid en omställning till elektrisk drivlina är det inte längre säkert att möjligheten kvarstår att ta kraft från drivlinan. Detta har lett till en efterfrågan på elektriskt separat drivna kraftuttag uppstått på marknaden. Syftet med denna studie är att undersöka och få en förståelse för inom vilket effektområde och vilken typ av elektrisk motor som är bäst lämpad för att separat driva ett kraftuttag. Målet är att med denna kunskap utveckla en modell som förenklar valet av lämplig elektrisk motor för ett givet fall av kraftuttag. Modellen testas med en effekt på 60 kW vilket resulterade i att en lågvarvig axial flux BLDC-motor anses bäst lämpad. Detta då en lågvarvig elektrisk motor kräver lägre utväxling för att uppfylla krävt vridmoment, vilket ger en lägre totalvikt. Totalvikt för testad effekt hamnar på 78,6 kg, vilket är tre gånger det funktionella kravet. Studien ger en indikation på att det med givna krav enbart är försvarbart att driva kraftuttag med separata elektriska motorer vid låga effekter, runt 10 kW. / In a time characterized by an endeavor for a more sustainable society. With formulated long-term climate targets for renewable energy sources and reduced emissions, vehicle developers are working to develop alternatives to internal combustion engines. In order to achieve set climate targets and at the same time improve the working environment with reduced noise, an electric driveline is considered a likely alternative. For heavy vehicles such as trucks that are often equipped with auxiliary accessories such as cranes, tipper trucks or cement rotators are dependent on a power take-off to drive hydraulic pumps and generators. When switching to an electric driveline, it is no longer certain that the possibility remains to take power from the driveline. This has led to a demand for electrically driven power take-offs on the market. The purpose of this study is to investigate and gain an understanding of the power range and type of electric motor that is best suited to drive a power take-off separately. The goal is to use this knowledge to develop a model that simplifies the choice of a suitable electric motor for a given case of power take-off. The model is tested with an output of 60 kW, which resulted in a low-speed axial flux BLDC-motor being considered best suited. This is because a low-speed electrical motor requires a lower gear ratio to meet the required torque, which gives a lower total weight. The total weight for the tested effect ends up at 78,8 kg, which is three times the functional requirement. The study gives an indication that with given requirements it is only justified to operate power take-offs with separate electric motors at low powers, around 10 kW.

Contexte : La participation sociale d’utilisateurs de fauteuils roulants peut être affectée par certains facteurs, tels que l’accessibilité et les caractéristiques individuelles de ces derniers, pouvant limiter leur pleine implication dans la réalisation des activités signifiantes de la vie quotidienne. Afin d’améliorer leur mobilité, différents prototypes de fauteuils roulants motorisés intelligents (FRMIs) sont en développement, à l’intention de personnes présentant des déficiences physiques, cognitives ou sensorielles, et qui sont dans l’incapacité d’utiliser un fauteuil roulant motorisé (FRM). Le but visé est de leur procurer davantage d’autonomie dans leurs déplacements, et tenter ainsi de répondre à leurs besoins en termes de mobilité et de participation sociale. Objectif : Explorer la littérature portant sur le développement de FRMIs afin de comprendre dans quelle mesure les prototypes existants répondent aux besoins réels des utilisateurs, d’identifier les limites des études, et de faire des recommandations pour mieux orienter le développement continu des FRMIs. Méthodologie : Un examen de la portée a été réalisé suivant les six étapes proposées par Arskeys et O’Malley (2005), puis bonifiées par Levac et al. (2010). Les études publiées en anglais ou en français, jusqu’à septembre 2020, ont été consultées. Résultats : Au total, 41 études ont été retenues pour l’analyse. Les résultats suggèrent que les différentes technologies intégrées aux FRMIs pourraient contribuer à répondre à certains besoins d’utilisateurs présentant différentes incapacités, contribuer à améliorer leur mobilité, procurer de l’autonomie et favoriser leur participation sociale. Par ailleurs, des résultats complémentaires ont permis d’identifier : (a) d’autres technologies, pouvant favoriser davantage le sentiment d’autonomie et de confort aux utilisateurs, et (b) d’autres usages possibles du FRMI en clinique. Une limite importante identifiée est l’absence d’études expérimentales pouvant permettre d’évaluer l’efficacité du FRMI. Le point de vue des proches-aidants est également peu rapporté dans la littérature. Conclusion : Des études futures seraient à envisager en vue d’améliorer les prototypes de FRMIs existants. / Background: The level of social participation among wheelchair users can be affected by factors such as accessibility, as well as their individual clinical profile, which can limit their full involvement in meaningful activities of daily living. To meet their needs in terms of mobility and social participation, different prototypes of intelligent powered wheelchairs (IPW) are being developed, in order to improve the mobility of people with physical, cognitive or sensorial impairments, who have difficulties using standard powered wheelchairs. Objective: The aim of this study was to map the existing literature on the nature of studies carried out on IPWs to better understand how the existing IPWs meet the needs of powered wheelchair users, and to better guide the ongoing development of IPWs. Methods: A scoping review was conducted in accordance with the six stages of Arskeys and O’Malley’s (2005) framework which was later enhanced by Levac et al. (2010). All studies available until September 2020, written in English or in French, were included. Results: A total of 41 studies were included in the scoping review. The results suggest that the various technologies integrated into IPWs could meet some of the needs of powered wheelchair users (PWu), could help improve mobility, provide independence, and promote social participation of some PWu. Moreover, additional results were identified: (a) other technologies, that could provide more independence and comfort to users, and (b) other clinical uses of IPW. An important limitation of the literature is the lack of experimental studies that could help assessing the efficiency of IPW. The point of view of caregivers is also less reported in the literature. Conclusion: Further studies should be considered to improve the functioning of the existing prototypes of IPW.

[pt] A Marinha do Brasil presta o seu apoio logístico em cenários, por vezes, inóspitos, a partir de uma rede logística que, na sua origem, formou-se com base em conceitos e necessidades operativas, podendo também conviver com ineficiências e acomodações pela falta de concorrentes. Em 2008, fruto de uma decisão política e estratégica, dentro do contexto das relações internacionais no qual o Brasil está inserido, iniciou-se o processo de aquisição de novos submarinos convencionais (S-BR) e o apoio à elaboração do projeto e construção de um submarino nuclear (SN-BR), que se constitui no mais complexo e significativo projeto conduzido pela Marinha nos últimos tempos. Não obstante a importância desse projeto, estaria a cadeia de suprimento de sobressalentes (CSS) da Marinha pronta para prestar o devido apoio logístico ao novo meio operativo? O atual desenho de rede da Marinha atende as necessidades deste apoio? Qual o atual estágio de desenvolvimento da CSS e como promover uma maior integração dessa rede, com vistas a um melhor gerenciamento? Em meio a poucos estudos sobre o assunto e uma significativa carência de informações, o presente trabalho apresenta respostas a essas e outras questões correlatas, que se mostram cada vez mais prementes, diante da previsão de início dos testes de mar do primeiro submarino já 2017. Indubitavelmente, a Marinha é reconhecida pela sua grande capacidade de organização e pelo comprometimento de seus profissionais, mas serão necessárias algumas ações a mais para vencer este enorme desafio logístico. / [en] The Brazilian Navy provides logistics support in areas, sometimes inhospitable, using a logistics network that, in its origin, was formed on the basis of military concepts and needs, and, sometimes coexisting with inefficiencies and without competitors. In 2008, the result of a political and strategic decision, in a context of international relations in which Brazil is inserted, began the process of acquiring new Brazilian hunter-killer Submarine (SSK) and the support for design and construction of the Brazilian Nuclear-Powered Attack Submarine (SSN), which constitutes the most complex and significant Navy project in recent times. Despite the importance of this project, the Navy spare parts supply chain (SSC) would able to provide the appropriate logistics support for the new submarines? The current Navy network design meets the needs of this support? What is the current development stage of SSC and how to upgrade the integration of this network for improve the SCM? Few studies about this subject exist and a significant lack of information, therefore, this presents answers to these and other related issues that are becoming increasingly pressing, given the early prediction of sea tests of the first SSK submarine in 2017. Undoubtedly, the Navy is known to be a great organizational due to her organizational skills and the commitment of its seamen, but this project will require a little more to overcome this huge logistical challenge.

Le bruit de la circulation routière, et en particulier le bruit des deux-roues motorisés, constituent une importante source de gêne sonore. Afin d’estimer l’exposition sonore dans les villes de plus 100 000 habitants, la directive européenne 2002/49/CE impose la réalisation de cartes de bruit stratégiques, basées sur l’indice Lden. Cet indice est également utilisé dans des relations exposition-réponse, afin de prédire les pourcentages de personnes gênées, notamment par le bruit du trafic routier. En couplant les cartes de bruit stratégiques et ces relations exposition-réponse, des cartes de gêne pourraient être établies. Toutefois, la pertinence de cet indice pour prédire la gêne due au bruit en milieu urbain est souvent remise en cause, car de nombreux facteurs acoustiques influents (e.g. les caractéristiques spectrales et temporelles) ne sont pas pris en compte par cet indice. Cette thèse vise à améliorer la caractérisation de la gêne due au bruit de trafic routier urbain en considérant différentes compositions de trafic et la présence des deux-roues motorisés. Dans ce but, des expériences sont menées en conditions contrôlées. Une première étude a porté sur l’influence de plusieurs facteurs acoustiques relatifs aux périodes de calme et aux bruits de passage de véhicules sur la gêne due au bruit de trafic routier urbain. Cette étude a conclu à l’influence de la présence de périodes de calme et du nombre de véhicules au sein du trafic routier urbain et à l’absence d’influence de l’ordre des véhicules routiers, de la position et de la durée des périodes de calme. Ces résultats ont été utilisés afin de mener la caractérisation physique et perceptive de différentes compositions de trafic routier urbain. La régression multi-niveau a été utilisée pour calculer la gêne, en considérant 1) des facteurs acoustiques influents à l’aide de combinaisons pertinentes d’indices et 2) un facteur non acoustique : la sensibilité au bruit. Dans les villes, le bruit routier est souvent entendu en situation de multi-exposition avec d’autres bruits. Dans le cadre de ces travaux de thèse, les situations de multi-exposition aux bruits routier et d’avion ont été étudiées. Pour cela, un travail semblable à celui mené pour le bruit de trafic routier urbain a été mené pour le bruit d’avion conduisant également à des combinaisons pertinentes d’indices. En vue de caractériser les gênes dues aux bruits de trafic routier et d’avion pour des situations de multi-exposition sonore, les données des précédentes expériences ainsi que celles d’une expérience conduite en situation de multi-exposition à ces bruits combinés ont été utilisées au travers d’une régression multi-niveau adaptée, comme cela a pu être mené dans la littérature. La régression multi-niveau a ainsi permis la proposition de modèles de gêne pour chaque source de bruit. Puis, la gêne totale due à des situations de multi-exposition à ces bruits a été étudiée, afin de mettre en évidence les phénomènes perceptifs mis en jeu. Des modèles de gêne totale ont été proposés, en utilisant les modèles de gêne due à chaque source. Enfin, les modèles de gêne obtenus pour chaque source et les modèles de gêne totale ont été confrontés aux données d’une enquête socio-acoustique. A cet effet, une méthodologie a été proposée afin d’estimer les différents indices des modèles à partir des valeurs du Lden, issues de cartes de bruit et utilisées pour définir l’exposition au bruit des personnes enquêtées. Cette confrontation a montré que les modèles proposés à partir d’expériences menées en laboratoire et couplés à la méthodologie d’estimation des indices à partir des valeurs du Lden permettent une bonne prédiction de la gêne in situ. / Road traffic noise, and in particular powered two-wheeler noise, constitute an important source of noise annoyance. In order to estimate the noise exposure in cities of more than 100 000 inhabitants, the European directive 2002/49/EC requires the elaboration of strategic noise maps, based on the Lden index. This index is also used in exposureresponse relationships, to predict the percentages of annoyed people, by road traffic noise for example. By coupling strategic noise maps and these exposure-response relationships, noise annoyance maps could be established. The relevance of this index to predict noise annoyance in cities is however often questioned, since many influential acoustical factors (e.g. spectral and temporal features) are not considered by this index. The aim of this thesis is to enhance the characterization of noise annoyance due to different compositions of urban road traffic including powered two-wheelers. To achieve this goal, experiments were carried out under controlled conditions. A first study concerned the influence of several acoustical features related to quiet periods and vehicle pass-by noises on the annoyance due to urban road traffic noise. This study demonstrated the influence of the presence of quiet periods and of the number of vehicles within the urban road traffic and to the absence of the influence of the order of the vehicle pass-by noises, the position and duration of quiet periods. These results were used to carry out the physical and perceptual characterization of different compositions of urban road traffic noise. Multilevel regression was used to calculate noise annoyance, by coupling combinations of indices relating to influential acoustical features and an individual factor: noise sensitivity. In cities, road traffic noise is often combined with other noises. In the framework of this thesis, noise exposure to road traffic noise combined with aircraft noise was studied. Therefore, the same work as the one performed for urban road traffic noise was carried out for aircraft noise, leading also to relevant combinations of noise indices. In order to characterize annoyances due to road traffic noise and to aircraft noise in a combined exposure situation, data from the previous experiments and from an experiment dealing with these combined noises were used through an appropriate multilevel regression, as done in literature. The regression allows annoyance models for each noise source to be proposed. Then, total annoyance due to combined noises was studied, in order to highlight the perceptual phenomena related to the combined exposure. Total noise annoyance models were proposed, using proposed annoyance model of each noise source. Finally, these single source annoyance models and total annoyance models were tested using data of a socio-acoustic survey. To do this, a methodology has been proposed to estimate the different indices involved in the annoyance models, from the Lden values obtained from the strategic noise maps and used to define the noise exposure of the respondents. This confrontation showed that the models proposed on the basis of experiments carried out under laboratory conditions and coupled with a methodology of estimation of the noise indices from Lden values, enabled a good prediction of in situ annoyance.

La pollution sonore est un problème majeur pour les résidents des zones urbaines. La directive Européenne 2002/49/CE impose aux états membres l’établissement de cartes de bruit. Ces dernières sont construites sur la base de l’indice énergétique Lden, également utilisé dans les relations dose-effet établies pour prédire la gêne. Toutefois, pour l’évaluation de la gêne due au bruit dans les zones urbaines, la pertinence de cet indice est souvent remise en question. En effet, de nombreuses études ont montré que les caractéristiques temporelles et spectrales des bruits environnementaux influencent aussi les réponses de gêne et ne sont pas prises en compte dans cet indice. Cette thèse vise à contribuer à l’amélioration de la caractérisation de la gêne due au bruit des véhicules routiers en ville. Elle est basée sur des expériences réalisées en laboratoire. Elle comprend deux parties principales. La première partie a comme objectif de progresser sur la caractérisation physique et perceptive du bruit des passages de divers véhicules routiers en milieu urbain tels que les bus, les deux-roues motorisés, les poids lourds et les véhicules légers. Une attention particulière a été portée sur la caractérisation de la gêne due aux deuxroues motorisés qui sont cités parmi les véhicules routiers les plus gênants et sont peu étudiés dans la littérature. Dans cette perspective, un indicateur acoustique caractéristique de la gêne due au bruit routier urbain a été déterminé : il rend compte de différents attributs auditifs gênants en associant la sonie, un indice spectral et deux indices de modulation proposés dans le cadre de ces travaux. Dans les zones urbaines, les riverains sont souvent exposés à la circulation routière en présence d’autres sources de bruit de l’environnement. L’objectif principal de la deuxième partie est la prédiction de la gêne totale due au bruit du trafic routier urbain combiné avec le bruit de tramway. Dans le but de caractériser la gêne totale, les phénomènes perceptifs liés à la combinaison de ces bruits sont tout d’abord étudiés. Ensuite, l’indicateur proposé précédemment pour caractériser la gêne due au bruit des passages de différents véhicules routiers est testé lorsque différents trafics routiers urbains sont considérés. Sur la base de ces résultats, des modèles permettant de caractériser la gêne due au bruit de trafic routier urbain combiné au bruit de tramway ont été proposés. / Noise pollution is a major concern for residents of urban areas. To date, the European directive 2002/49/CE requires member states to represent community noise through noise maps. These are produced using the Lden (day-evening-night level) index which is also employed for dose-effect relationships in noise annoyance prediction. However, for the assessment of noise annoyance in urban areas, its relevance is often questioned. Numerous studies have shown that noise annoyance due to community noise is not solely based on the sound pressure level and other acoustical signal characteristics such as temporal and spectral features influence noise annoyance ratings. This thesis aims to improve the assessment of noise annoyance due to various road vehicle noises in cities. It is based on experiments carried out in laboratory conditions and comprises two main parts. The first addresses the enhancement of the physical and perceptual characterization of annoyance due to various urban road vehicle pass-by noises, such as buses, poweredtwo- wheelers, heavy vehicles and light vehicles. A specific focus is put on the characterization of annoyance due to powered-two-wheelers which are among the most annoying road vehicles and studied little in the existing literature. An indicator accounting for annoyance-relevant auditory attributes of urban road vehicle pass-by noises is determined: it comprises loudness, a spectral index and two modulation indices proposed in this work. In urban agglomerations, people are often exposed to road traffic in presence of a variety of other environmental noise sources. The focal point of the second part is on the prediction of total annoyance due to urban road traffic noise combined with tramway noise. In the aim of adequately characterizing total annoyance, first the perceptual phenomena involved in annoyance due to the combination of the sources are studied. Furthermore, the analysis allows for the testing of the proposed noise annoyance indicator for the characterization of urban road traffic noise. To characterize annoyance due to tramway noise, an indicator determined in a recent study is employed. Based on these indicators and the findings regarding perceptual phenomena, models for the prediction of total annoyance due to combined urban road traffic and tramway noise are proposed.

Sport Airport complex Brno-Medlánky is nestled in the undulating hilly terrain in fields just beyond populated areas in Brno-Medlánky. The history of the airport dates back to 1924 when it was built the first wooden hangar for training purposes glider flights. Current state urban of airport is orderless. The aim is to streamline the complex and give it the order, allowing easy and efficient orientation in the space. The main intervention was the creation of a new central building - Aviation Museum. The concept of the design is based on the division of the whole area into two branches - communication axes, based on the mass preserved historic wooden hangars. Between the two communication arms is inserted a central axis on which is located the heart of the complex - Aviation Museum. It is a building organic form, inspiring axially symmetric wingspan (bird, airplane, beetle). It is this symmetry axis of the building creates a view towards building on the runway. Mass of the building used by the sloping terrain and is partially sunk under the ground. Building volume follows an upward slope from the outside and blends with the surrounding terrain. The internal layout consists of three floors, one of them is completely sunk below ground level and second half. The main entrance to the gallery is located in the uppermost floors, the direction of the exhibition is therefore directed downwards into the basement. The exposition is divided into six parts: RC models exposure, gliders exposure, powered aircraft exposure, screening room, children's exposure and air trainers. Other areas consist of building technical facilities. In the basement there is a workshop with aircraft lift, with the possibility of placement unexposed aircrafts. The supporting system of the building consists of two parts: reinforced concrete tubs and arched steel structure with a span of 50m.

Traditional fabrication methods used to manufacture biosensors for physiological, therapeutics, or health monitoring purposes are complex and rely on costly materials, which has hindered their adoption as single-use medical devices. The development of a new kind of wearable and implantable electronics relying on inexpensive materials for their manufacturing will pave the way towards the ubiquitous adoption of sticker-like health tracking devices.<div>One of growing and most promising applications for biosensors is the continuous health monitoring using mechanically soft, stretchable sensors. While these healthcare devices showed an excellent compatibility with human tissues, they still need highly trained personnel to perform multi-step, prolonged fabrication for several functioning layers of the device. In this dissertation, I propose low-cost, scalable, simple, and rapid manufacturing techniques to fabricate multifunctional epidermal and implantable sensors to monitor a range of biosignals including heart, muscle, or eye activity to characterizing of biofuids such as sweat. I have also used these devices as an implant to provide heat therapy for muscle regeneration and optical stimulation of neurons using optogenetics. These devices have also combined with those of triboelectric<br>nanogenerators to realize self-powered sensors for monitoring imperceptible mechanical biosignals such as respiratory and pulse rate.</div><div>Food health and safety has also emerged as another important frontier to develop biosensors and improve the human health and quality of life. The recent progresses on detecting microbial activity inside foods or their packages rely on development of highly functional materials. The existing materials for fabrication of food sensors, however,<br>are often costly and toxic for human health or the environment. In this dissertation, I proposed biocompatible food sensors using protein/PCL microfibers to reinforce the protein microfibrous structure in humid conditions and exploit their excellent hygroscopic properties to sense biogenic gas, as an indicator for early detection of food spoilage. Finally, my battery-free food sensors are capable of monitoring food safety with no need of extra measurement devices. Collectively, this dissertation proposes cost-effective solutions to solve human health issues, enabled by developing low-cost, functional materials and exploiting simple fabrication techniques.<br></div>
