Le concept de réseau d'interactions est central en Écologie et différents modèles et méthodes ont été utilisés. Ce travail de thèse met en relation deux approches développées par des courants séparés : l'étude des matrices de communauté et les analyses entrée-sortie. Il confronte leurs hypothèses aux propriétés fondamentales des écosystèmes estuariens. Il précise explicitement les liens entre les différentes matrices, ainsi que la signification des mixed trophic impacts. Les matrices de la storage et de la throughflowanalyses sont reliées à des jacobiennes de modèles à compartiments dont les flux sont contrôlés par les compartiments donneurs ou receveurs. Contrairement à ce qui est le plus souvent présenté dans la littérature, l'analyse des mixed trophic impacts est ici interprétée en terme de présence-absence du compartiment considéré. Avec les données disponibles sur les réseaux trophiques de cinq estuaires européens, des matrices qualitatives et quantitatives sont construites afin de réaliser des analyses de sensibilité. Ces premières explorations montrent des niveaux d'incertitudes très élevés, et ceci même pour le signe des prédictions. Par ailleurs, ce travail de thèse approfondit les possibilités d'étude de dynamiques transitoires à partir de la matrice de communauté. Il souligne des éléments importants qu'il est nécessaire de prendre en compte lorsque ces approches sont choisies.

Networks are a key concept in ecology and a number of models and methods have been used. This PhD dissertation links two approaches, the community matrix and input-output analyses, which have been developed by separate streams of theory. It compares their assumptions with important features of estuarine systems. It explicitly analyses the links between the matrices and the significance of the mixed trophic impacts analysis. Matrices of storage and throughflow analyses are linked to Jacobian matrices of donor or recipient controlled compartment models. Unlike most of what can be seen in the litterature, here the mixed trophic impacts are interpreted as the effects of a compartment being present or absent. Using available data in the case of five European estuaries, qualitative and quantitative matrices are built in the aim of performing sensitivity analyses. First explorations reveal high levels of uncertainties, even in the sign of the predictions. Furthermore, this work examines in more details the possibilities to explore transient dynamics from the community matrix. This PhD dissertation emphasises important features which are necessary to consider when choosing such approaches.

Background and Objectives: I investigated the use of sensitivity analyses in assessing statistical results or analytical approaches in three different statistical issues: (1) accounting for within-subject correlations in analyzing discrete choice data, (2) handling both-armed zero-event studies in meta-analyses for rare event outcomes, and (3) incorporating external information using Bayesian approach to estimate rare-event rates. Methods: Project 1: I empirically compared ten statistical models in analyzing correlated data from a discrete choice survey to elicit patient preference for colorectal cancer screening. Logistic and probit models with random-effects, generalized estimating equations or robust standard errors were applied to binary, multinomial or bivariate outcomes. Project 2: I investigated the impacts of including or excluding both-armed zero-event studies on pooled odds ratios for classical meta-analyses using simulated data. Five commonly used pooling methods: Peto, Mantel-Haenszel fixed/random effects and inverse variance fixed/random effects, were compared in terms of bias and precision. Project 3: I explored the use of Bayesian approach to incorporate external information through priors to verify, enhance or modify the study evidence. Three study scenarios were derived from previous studies to estimate inhibitor rates for hemophilia A patients treated with rAHF-PFM: 1) a single cohort of previously treated patients, 2) individual patient data meta-analysis, and 3) an previously unexplored patient population with limited data. Results and Conclusion: Project 1: When within-subject correlations were substantial, the results from different statistical models were inconsistent. Project 2: Including both-armed zero-event studies in meta-analyses increased biases for pooled odd ratios when true treatment effects existed. Project 3: Through priors, Bayesian approaches effectively incorporated different types of information to strengthen or broaden research evidence. Through this thesis I demonstrated that when analyzing complicated health research data, it was important to use sensitivity analyses to assess the robustness of analysis results or proper choice of statistical models.

Le véhicule électrique est aujourd’hui présenté comme l’une des solutions alternatives sérieuses au véhicule à moteur à combustion interne, visant à limiter la consommation d’énergies fossiles, ainsi que les émissions de polluants locaux et de gaz à effet de serre. L’évaluation des forces et faiblesses de cette technologie au regard de l’environnement est aujourd’hui limitée, compte tenu notamment du peu de retour d’expérience sur ce type de véhicules.L’objectif de ce travail de recherche est de proposer une approche combinant une connaissance fine du véhicule étudié (obtenu notamment par des essais expérimentaux et l’utilisation de modèles de consommation) et de la méthode d’évaluation environnementale Analyse de Cycle de Vie (ACV), pour identifier les paramètres clefs du bilan environnemental, et par différentes analyses de sensibilité, d’en proposer une analyse détaillée. Pour y parvenir, des essais expérimentaux ont été réalisés sur un véhicule électrique à usage essentiellement urbain et son équivalent thermique. Un modèle permet d’estimer les consommations de véhicules selon leurs spécificités (chimie et capacité de batterie, rendement de la chaîne de traction) et leurs conditions d’utilisation (trafic, usages d’auxiliaires). Des hypothèses et scénarios sont également établis sur la durée de vie des batteries qui équipent le véhicule. Les jeux de données obtenus sont mis en œuvre dans l’ACV d’un véhicule électrique, et les résultats obtenus interprétés puis comparés à ceux du véhicule thermique équivalent. Enfin, analyses de sensibilité et test de divers scénarios permettent l’identification des paramètres clefs du bilan environnemental.

Today, the electric vehicle is seen as a potent substitute to the internal combustion engine vehicle, aiming at reducing consumption of fossil fuels, and emissions of local pollutants and greenhouse gases. The assessment of strengths and weaknesses of this technology from the environmental viewpoint is currently limited, especially considering the lack of experiment feedbacks.The objective of this research is to offer an approach combining a deep understanding of the studied vehicle (through experiments and use of consumption patterns) and the environmental assessment method “Life Cycle Analysis” (LCA), to identify the key parameters of environmental appraisal, and relying on different sensitivity analysis, to propose a detailed analysis.To achieve this, experimental tests were carried out on an urban electric vehicle and its internal combustion engine equivalent. A model was built to estimate the consumption of electric vehicles according to their characteristics (chemistry and battery capacity, vehicle energy efficiency) and use (traffic, use of auxiliaries). Assumptions and scenarios are also made on the lifetimes of batteries in the vehicle. The data sets obtained are implemented in the life cycle analysis of an electric vehicle, and the results are interpreted and compared to its internal combustion engine equivalent vehicle. In the end, sensitivity analysis and test of…

Proposer une offre en logements adaptée aux différents besoins et préférences des ménages représente un enjeu important pour les acteurs publics de l’aménagement. Ces besoins et préférences dépendent des caractéristiques des ménages et des changements qu’ils peuvent connaître dans leur cycle de vie (mise en couple, naissance, séparation…). Les facteurs participant aux choix résidentiels sont nombreux (attributs du logement, caractéristiques de l’environnement résidentiel) et interviennent différemment selon les types de ménages. Les dynamiques résidentielles impliquent ainsi une grande variété d’éléments, en interaction les uns avec les autres, et les relations de cause à effet sont difficiles à identifier. Par conséquent, il n’est pas possible de prévoir le comportement résidentiel des ménages pas plus que leurs évolutions possibles sans outil adapté.Pour étudier les dynamiques résidentielles intra-urbaines, nous utilisons dans cette thèse un modèle de simulation des mobilités résidentielles (Mobisim-MR) intégré dans une plateforme de simulation LUTI individu-centrée : Mobisim. Mobisim-MR permet de déterminer, pour chaque année de simulation, les ménages qui déménagent et leur nouvelle localisation résidentielle. En amont de Mobisim-MR, un modèle de simulation des évolutions démographiques (Mobisim-Démo) a été créé au sein de la plateforme Mobisim. Il permet de reproduire de manière dynamique et individu-centrée l’évolution des ménages dans leur cycle de vie. Une partie de la thèse est dédiée au paramétrage ces deux modèles, étape préalable nécessaire à la simulation de scénarios. Un autre volet de la thèse concerne l’exploration du comportement du modèle Mobisim-MR pour évaluer la stabilité des résultats de simulation et leur cohérence (analyse de sensibilité). L’utilisation de modèles individu-centrés est relativement récente en géographie, d’où l’absence de protocole standard pour l’exploration de tels modèles. Un protocole spécifique a été conçu pour explorer le comportement de Mobisim-MR. Ce protocole tient compte de la nature des paramètres du modèle, des contraintes techniques de simulation et de l’objectif pour lequel le modèle a été conçu.Le dernier volet de la thèse consiste en des analyses thématiques visant à étudier l’impact de deux scénarios de politiques de construction de logements sur l’agglomération du Grand Besançon. Ces analyses montrent la capacité de Mobisim-MR à répondre à des questions concrètes d’aménagement et à apporter des éléments de discussion aux acteurs publics en charge des politiques de logement.

To ensure that housing supply is suitable to households’ needs and preferences represents a major planning concern. These needs and preferences depend on the households’ characteristics and on their lifecycle changes (union, birth, divorce…). Residential choice factors are numerous (housing and residential environment characteristics) and their role is often different according to the types of households. Residential dynamics involve a great variety of elements, in interaction with each…

Le secteur du bâtiment est en évolution et se doit de répondre aux problématiques environnementales actuelles aussi bien dans la construction neuve que dans la réhabilitation. La simulation thermique offre le moyen de répondre à cette problématique, mais se limite à une estimation des performances spécifiques aux paramètres qui ont été définis. Ce travail de thèse propose une méthodologie basée sur les puissances de calcul actuelles pour évaluer le comportement du bâtiment sur différentes plages de variation des entrées. Ces variations permettront, en fonction des propriétés qui leur sont attribuées, de rechercher des solutions de réhabilitation ou d'évaluer l'incertitude sur les sorties du modèle thermique. Afin de réaliser cela, des méthodes d'analyse de sensibilité performantes sont utilisées à travers un outil d'analyse spécifiquement développé pour le logiciel de simulation EnergyPlus. Cet outil permet une évaluation quasi automatique du modèle énergétique de bâtiment via : des techniques d'échantillonnage éprouvées LHS et LP-Tau, des techniques d'analyse performante pour un nombre de simulations réduit RBD-FAST et RBD-SOBOL, une gestion avancée des entrées et sorties permettant une évaluation détaillée du bâtiment, quelle que soit sa géométrie. Les techniques d'analyse de sensibilité sont employées pour proposer une vision précise des principales relations présentes au sein du modèle. Pour répondre à la contrainte du coût de calcul, la recherche de solution est réalisée à travers un méta-modèle issu d'une décomposition en polynôme de chaos. Une interface graphique utilise cette approximation du modèle complexe du bâtiment pour proposer de façon instantanée une vision claire du comportement de chaque entrée sur les sorties, ainsi que leurs tendances et les plages de variation idéales afin de choisir des solutions. Il est possible de coupler la recherche de solution à l'analyse d'incertitude afin de proposer des solutions robustes et identifier les principales raisons d'un écart entre simulation et réalité. La méthodologie des travaux de thèse encourage à l'optimisation de la compréhension du modèle plus qu'à la recherche d'une solution particulière.L'objectif de la démarche est de fournir des outils d'analyse afin d'aider l'expert dans la recherche de solution et ainsi de mettre en place des représentations graphiques qui facilitent la compréhension du système bâtiment, pour un gain en transparence et l'intégration de nombreuses contraintes de projet.

The building sector is evolving and has to meet the current environmental issues in both new construction and rehabilitation. The thermal simulation provides the mean to address this problem, but the estimated performance is limited to a specific set of parameters that have been defined. This thesis proposes a methodology based on the increased computing power to assess the building behaviour on different ranges of the inputs variation. Depending on the properties allocated to them, the changes of the variations will allow to seek solutions to restore or to…

▼ Short-fiber-reinforced thermoplastics are widely used in industry. They are light-weight, have excellent mechanical properties and can be processed via injection moulding. This allows the mass production of high-quality components with excellent geometric accuracy. Their superior isolation properties make them a good choice for electrical housings in the automotive sector. Due to the importance and precise nature of applications, in which such products are employed, a deep understanding of their deformation and fractures under specific conditions is essential. A typical example of such thermoplastics is polybutylene terephthalate (PBT). In this thesis, an evaluation of mechanical and morphological properties of short-glass-fibre-reinforced (SGFR) PBT and SGFR PBT TPEE (thermoplastic polyester elastomer: an impact-enhancing additive) is performed, emphasising the effect of TPEE on strain-rate-dependent behaviour and plastic deformation together with assessment of energy-dissipation levels. Experimental studies including uniaxial tensile testing performed at different strain rates revealed degradation in the overall tensile properties and a reduced strain-at-break value as result of TPEE addition to PBT. Furthermore, cyclic tests and incremental loading tests showed that the plastic strain at different loading rates increased with introduction of TPEE in the composite. Dynamic mechanical analysis of the studied materials revealed an increase in viscosity, loss-modulus values and damping capability (tan δ) of the TPEE composite over a specified frequency range, while a damage analysis on basis of degradation of the Young's modulus demonstrated increased damage initiation and accumulation for this composite. A study of fracture-surface morphology of tensile-tested samples uncovered the effect of microstructure on variations in mechanical properties, observed in the experimentation part of the study. The analysis demonstrated a significant effect of microstructure on mechanical performance of the PBT composites. The increased plastic strain was proved to be a result of higher plasticity observed in the fractographs. Larger ductile-area fractions were measured on PBT-GF10 TPEE fracture surfaces at all strain rates, in addition to increased void nucleation and relatively insufficient fibre-matrix interfacial adhesion in the TPEE composite. This was evident by the stretched gaps around pull-out glass fibres. The increased energy dissipation was linked to higher deformation and plasticity of the fracture surface. Moreover, an increased viscoplastic material flow was observed in the TPEE composite, demonstrated by formation of conic structures around glass fibres, which, in turn, enhanced the damping properties of this composite.

▼ Pesticides volatilize from soil and plant surfaces to the atmosphere after spray applications in agricultural fields which can cause inhalational exposure to bystanders. It is important to quantify such volatilization with reasonable confidence for risk assessment of the inhalation exposure. A mechanistic model was developed here to simulate the underlying transport processes and deploy it as a standalone tool that a regulatory body can use to predict volatilization emissions of various pesticides for determination of inhalation exposure. The overall volatilization model includes a soil sub-model and a plant sub-model. The model accounts for the effect of meteorology, soil conditions, pesticide adsorption and volatilization. The soil model simultaneously resolves the soil profile of temperature, moisture, and pesticide concentrations to compute the time-dependent volatilization. The numerical model for soil treatment was in good agreement with an analytical solution at stagnant boundary conditions. The model performance of 14 pesticides against the analytical solution showed coefficient of determination (R²) values of 0.76 to 0.99 and index of agreement (IOA) values of 0.43 to 0.98. The soil model was also validated with observations at field conditions with variable meteorology. The time-dependent predicted volatilization compared well against measurements of two surface treated pesticides - metolachlor and triallate with R² value of 0.4 and 0.7, respectively. The model prediction of the fumigant volatilization of 1,3-dichloropropene was in good agreement with the field observations (R²=0.8 and IOA=0.9). The plant model utilizes a simple resistance scheme with mass transfer of the pesticide on the leaf surface through a diffusive canopy boundary and an atmospheric boundary layer above the canopy. The model also accounts the loss of pesticide mass on the leaf surface due to penetration into leaf cuticle and photo-degradation as first-order kinetic rates. Volatilization of chlorpyrifos from plant surface was predicted reasonably well with the field observations (R² = 0.96 and IOA = 0.9). Uncertainty analyses with Monte Carlo simulations of metolachlor volatilization showed that the soil model was most sensitive to pesticide adsorption to soil. A negative Pearson correlation coefficient (r = -0.98) illustrates that the volatilization prediction will largely decrease with high values of the adsorption coefficient. The soil model was not significantly sensitive to the Henry’s law constant of the pesticide. Monte Carlo simulations of chlorpyrifos volatilization showed that the plant model was significantly sensitive to the Henry’s law constant, solubility, and air diffusivity of the pesticide. Sensitivity analyses of the model to different locations and seasons with varying meteorological conditions were also performed. Large variations in the soil model predictions was noted with volatilization significantly increasing at hot climatic… Advisors/Committee Members: Young, Valerie (Advisor).

Durante décadas, problemas relacionados à estabilidade de tensão ou, segurança de tensão, têm despertada a atenção crescente de pesquisadores do setor elétrico. O crescimento da economia e o aumento do consumo de energia elétrica, aliados à falta de investimentos nos setores de geração e transmissão, têm levado o sistema elétrico de potência a operar muito próximo de seus limites. Desta forma, a habilidade do sistema em manter um nível operacional satisfatório, após a ocorrência de alguma contingência, pode ficar comprometida. Este trabalho avalia a segurança de tensão através de um método simples, eficiente e rápido computacionalmente, além de propor ações de reforço para melhorar a margem de carregamento do sistema elétrico. A análise da rede é função dos caminhos de transmissão de potência ativa e um modelo matemático muito simples é utilizado. Quanto às ações de reforço, a análise de sensibilidade fornece as barras mais adequadas ao redespacho de potência ativa e reativa. Um processo iterativo é estabelecido com o intuito de recomendar ações de controle e fornecer condições de segurança de tensão menos severas. Os resultados apresentados para um sistema real de 34 barras demonstram a eficácia da metodologia desenvolvida

Voltage stability or voltage security analysis has motivated an expressive attention of power systems researchers. The economy growth and the increased electric energy consumption, allied to the lack of investments in generation and transmission areas, have led electrical power systems to operate very close to their limits. Therefore, they cannot be able to operate in a secure way after some contingencies. In this work, a simple and fast method evaluates voltage security and proposes conditions to improve the loading margin. System analysis is carried out in terms of active power transmission path. Sensitivity analysis provides the most adequate buses to active and reactive power redispatch. A sequential iterative methodology to reinforce system conditions is presented. The results for a real 34-bus system demonstrate the efficiency of proposed methodology

[pt] O problema do fluxo máximo multiterminal é uma extensão do conhecido problema de fluxo máximo entre um nó origem e um nó destino de uma rede. Este problema surge no contexto de fluxos em redes, tema que possui diversas aplicações, especialmente nos campos de transporte, telecomunicações e energia. No caso multiterminal, o fluxo máximo é calculado entre todos os pares de nós da rede. No referente a uma rede simétrica, este problema pode ser resolvido, obviamente, pela execução do algoritmo de fluxo máximo n(n − 1) 2 vezes, onde n é o número de nós da rede. Os tradicionais métodos encontrados na literatura o conseguem com apenas n − 1. O presente trabalho busca elaborar um algoritmo capaz de resolver o problema multiterminal com uma complexidade menor do que os métodos da literatura. A recente teoria da análise de sensibilidade, em que se estuda a influência da variação de capacidade de uma aresta nos fluxos máximos multiterminais, é utilizada para a construção do algoritmo. Técnicas dos tradicionais métodos, como a de contração de nós, também compõem o método. Ao final, o algoritmo é testado computacionalmente com todas as suas variações e heurísticas adicionadas. Para um determinado caso, o algoritmo se mostrou com eficiência semelhante a dos métodos tradicionais. Novas variações e heurísticas são listadas para futuras pesquisas.

[en] The multi-terminal maximum flow problem is an extension of the well known single source-single terminal maximum flow problem. These problems arise in the context of network flows, theme which has various applications, especially in the fields of transport, telecommunications and energy. In the multiterminal case, the maximum flow is calculated between all pairs of nodes. Clearly, this problem can be solved, in a symmetric network, by computing the maximum flow algorithm n(n − 1) 2 times, where n is the number of nodes of the network, but the traditional methods found in the literature can do it with only n − 1 computations. This paper seeks to elaborate an algorithm able to solve the multiterminal problem with a complexity lower than the methods of the literature. The recent theory of sensitivity analysis, which studies the influence of an edge capacity variation on multi-terminals maximum flows, is employed on the construction of the algorithm. Techniques of the traditional methods, such as the contraction of nodes, are also part of the method. Finally, the algorithm is computationally tested with all its variations and added heuristics. For a given case, the algorithm showed an efficiency very close to the ones of traditional methods. New variations and heuristics are listed for future research.

▼ Brake squeal noise is caused by the dynamic instability originating from the rotational friction in the brake system. An asymmetric stiffness matrix is the end result of the dynamic friction in a finite element model of a brake system. Complex eigenvalue analysis has been used to assess the brake squeal frequencies and their corresponding instabilities of an asymmetric eigenvalue problem (AEVP). The double shift QR or the QZ algorithms should be applied to solve a real AEVP. Other algorithms produce a number of fictitious complex eigenvalues. The optimization problem for the brake squeal noise consists of a complex-valued objective function (COF) and physical design variables (PDV). A direct solution has been hampered by many unknowns between the COF and PDV. Nonetheless, an optimal solution is possible if the problem is separated into two steps. In the first step, sensitivity analysis is used to calculate the optimal components' eigenvalues capable of eliminating all unstable eigenvalues. If only the sensitive components' eigenvalues for each unstable eigenvalue are chosen as design variables, finding an optimal solution is virtually guaranteed. It was first discovered that one of the rotor in-plane doublet modes has the opposite sign to the other in the real parts of the sensitivity, and this precludes eliminating the unstable eigenvalues, which are dominated by rotor in-plane modes. However, it was also found that the corresponding unstable eigenvalues can be eliminated if we use the frequency separation of these modes, which is obtainable by including the rotational effect into the FE model. Once the optimal components' eigenvalues are found in the first step, the second step of the optimization involves the real-valued objective function. Resolving complex eigenvalues in essence allowed us to resume the conventional optimization with response surface methodology. The optimal physical dimensions are thus obtained in this step. Using this approach, the double-piston-floating-type-caliper disk brake system is successfully optimized. Advisors/Committee Members: Kikuchi, Noboru (advisor).

[pt] Parâmetros mecânicos utilizados na análise e projeto de estruturas, tais como módulo de elasticidade e tensão de escoamento do material assim como cargas, são na verdade variáveis aleatórias e não determinísticas como se considera normalmente. Conseqüentemente, as respostas das estruturas, tais como deslocamentos e tensões, são também variáveis aleatórias e, portanto há incerteza quanto à determinação dessas variáveis. Nesse trabalho as incertezas relativas aos parâmetros mecânicos dos materiais e, por conseguinte as incertezas quanto às respostas da estrutura, serão consideradas no projeto ótimo de estruturas reticuladas planas tais como treliças e pórticos. Para a determinação da resposta incorporando incertezas será usado o método de análise estatística linear. As análises de sensibilidade serão feitas pelo método analítico direto e o algoritmo de otimização empregado será o de pontos interiores.

[en] Mechanical parameters used in the analysis and design of structures, such as the elasticity modulus and the yielding stress for the material as well as the loads, are in fact, random rather than deterministic variables as they are usually considered. Consequently, the structural response, such as displacements and stresses, are also random variables, and in this way, there are uncertainties while determining these variables. In this work the uncertainties related to the mechanical parameters for the material and, as consequence, the uncertainties corresponding to structural response will be taken into account in the optimum design of framed structures, such as trusses and frames. For the determination of the structural response considering uncertainties, the linear statistical method will be applied. The sensitivity analyses will be performed by the direct analytical method and the interior point algorithm will be used as optimization algorithm.

La généralisation planifiée du Bâtiment à Énergie POSitive est un enjeu important de développement durable, notamment dans une vision à long terme. Cependant, concevoir de tels bâtiments à moindre impact environnemental et à des coûts maîtrisés pour le marché constitue une problématique complexe pour les professionnels du secteur. Ces travaux de thèse se sont ainsi intéressés au développement d’une méthodologie permettant de fournir une aide à la décision opérationnelle et robuste pour l’écoconception de maisons à énergie positive (MEPOS). Basée sur l’optimisation multicritère (via un algorithme génétique), la démarche proposée associe au sein d’une plateforme multi-outils, simulation thermique dynamique, analyse de cycle de vie, et fonctions de coût de construction, pour identifier, sur une base multicritère (front de Pareto) et sur le cycle de vie, des concepts de MEPOS performantes et fournir au décideur une description des meilleurs compromis. Également intégrées dans la plateforme, des méthodes d’analyses de sensibilité et d’incertitude offrent la possibilité de sélectionner les variables de conception les plus influentes en amont de l’optimisation, et d’évaluer le risque de non-robustesse d’une décision en aval de l’optimisation, notamment au regard des incertitudes sur le comportement des occupants (avec un modèle stochastique d’occupation), et de l’évolution prévisible du climat jusqu’à la fin du siècle. Via une collaboration avec un constructeur, la méthodologie a été appliquée en temps réel au sein d’un processus de conception intégrée d’une MEPOS.

The planned generalisation of Plus Energy Buildings constitutes an important topic for sustainable development, especially in a long term vision. However, designing such buildings at lower environmental impact and with competitive cost for the market constitutes a complex issue for the sector’s professionals. This thesis focused on the development of a methodology providing an operational and robust decision support to eco-design plus-energy houses. Based on multi-criteria optimisation (via a genetic algorithm), the proposed approach combines in a multi-tools platform, dynamic building energy simulation, life cycle assessment, and cost construction functions, in order to identify, on a multi-criteria (Pareto front) and life cycle basis, efficient plus-energy houses concepts and to provide decision maker a description of the best compromises. Also included in the platform, sensitivity and uncertainty analysis methods offer the possibility to select the most influent design variables before optimisation, and to evaluate the non-robustness risk of a decision after optimisation, especially regarding uncertainties on occupants’ behaviour (with a stochastic model of occupancy) and climate’s predictable evolution up to the end of the century. Via collaboration with a constructor, the methodology was applied in real-time throughout a integrated design process of a plus-energy house.

▼ Electric power has become an essential part of daily life: we plug our electronic devices in, switch our lights on, and expect to have power. As the availability of power is usually taken for granted in modern societies, we mostly feel annoyed at its absence and perceive the importance of power during outages which have severe effects on the public order. Blackouts have had disastrous consequences for many countries and they continue to occur frequently. Such examples demonstrate the necessity for careful analysis and planning of power grids, to ultimately increase the reliability of power grids. The power grids have evolved due to economic, environmental and human-caused factors. In addition to the contingency analysis, nowadays, the operation and planning of power grids are facing many other challenges (such as demand growth, targeted attacks, cascading failures, and renewable energy integration). Thus, many questions arise, including: which buses (nodes) to connect with a new line (link)? What are the impacts of malicious attacks on power grids? How may an initial failure result in a cascade of failures? How to prepare for the integration of renewable energy? Answering such questions requires developing new concepts and tools for analysing and planning of power grids. Power grids are one of the largest and the most complex man-made systems on earth. The complex nature of power grids and its underlying structure make it possible to analyse power grids relying on network science. The applications of network science on power grids have shown the promising potential to capture the interdependencies between components and to understand the collective emergent behaviour of complex power grids. This thesis is motivated by the increasing need of reliable power grids and the merits of network science on the investigation of power grids. In this context, relying on network science, we model and analyse the power grid and its near-future challenges in terms of line removals/additions, malicious attacks, cascading failures, and renewable integration.

Doutoramento em Economia

The dissertation is focused on the domain of financial stability, then addressing the perspective of the credit risk of default. The quantification of this risk in ensured through the estimations of the parameter Probability of Default (PD), as established in Basel 2. Regarding these estimations, it is presented a proposal of a structured framework of quantitative validation procedures, covering in detail the validation of time series, discriminatory power, calibration and stability of rating systems. The contribution of this thesis results, also, from the presentation of three new conceptions based on the exploration of the concept of credit risk profile, including the respective empirical analyses: Forward-looking credit risk pressure indicators; Anticyclical minimum capital ratios, variable depending on the credit risk profile of banks, complemented by a countercyclical incentives scheme; Sensitivity analyses to assess the impact on banks‟ solvency of a deterioration of risk weighted assets (RWA) and expected losses (EL), caused by a shock on the probability and level of default of credit portfolios. To conclude, we emphasize the advantages of investing in collecting and exploring information on banks‟ credit risk portfolios profiles, in order to, namely, developing new tools that may contribute to achieve the goal of financial stability.

A presente investigação enquadra-se no domínio da estabilidade financeira, focando a perspectiva do risco de incumprimento associado ao crédito. A quantificação deste risco é concretizada através das estimativas do parâmetro Probabilidade de Incumprimento (PD), estabelecido por Basileia 2. Sobre estas estimativas, é apresentada uma proposta de estrutura de procedimentos de validação, com especial incidência em séries históricas, poder discriminante, calibração e estabilidade dos sistemas de notação. O contributo científico do estudo resulta, ainda, da apresentação de três novas concepções baseadas na exploração do conceito de perfil de risco de crédito, incluindo as análises empíricas correspondentes: Indicadores avançados sobre a pressão do risco de crédito; Rácios mínimos de capital anticíclicos, variáveis em função do perfil de risco de crédito dos bancos, complementados por um esquema de incentivos contracíclicos; Análises de sensibilidade para avaliação do impacto na solvabilidade do agravamento dos activos ponderados pelo risco (RWA) e das perdas esperadas (EL), devido a choques na probabilidade e nos níveis de incumprimento das carteiras de crédito. Como conclusão sublinham-se as vantagens do investimento em informação sobre os perfis de risco das carteiras de crédito dos bancos, com vista, nomeadamente, ao desenvolvimento de novos meios que contribuam para a prossecução do objectivo de estabilidade financeira.

À mesure que les performances intrinsèques des bâtiments s’améliorent, les usages énergétiques non réglementés, que nous associons à une notion d’intensité énergétique des usages, prennent de plus en plus d’importance dans le bilan des consommations des bâtiments. De plus, les bâtiments performants font apparaître des problématiques au niveau de l’exploitation des installations. Ces constats nous permettent d’affirmer qu’il est aujourd’hui important de proposer un cadre pour le suivi et l’optimisation de la sobriété énergétique des usages et l’exploitation performante pour la maîtrise des consommations énergétiques réelles des bâtiments. Cette thèse propose tout d’abord de développer des modèles polynomiaux de prédiction de la consommation énergétique tous usages en fonction des facteurs caractérisant l’intensité d’usage, la qualité d’usage et la qualité d’exploitation. Pour cela, nous utilisons le logiciel EnergyPlus afin de réaliser des simulations énergétiques dynamiques (SED) sur des valeurs de paramètres définis par la méthode des plans d’expérience D-optimaux. Le modèle polynomial créé permet alors d’effectuer, avec un faible temps de calcul, une propagation des incertitudes sur les consommations d’énergie calculées. Pour ce faire, nous utilisons les données mesurées en exploitation dans le cadre de la mesure et de la vérification de la performance énergétique, associées à une incertitude concernant leur valeur. Nous pouvons alors déterminer l’incertitude globale sur les consommations énergétiques et identifier les pistes pour la réduire, permettant ainsi un meilleur suivi et encadrement de la consommation énergétique réelle.

Since building envelope and MEP systems characteristics regularly improve, the weight of non-regulatory energy end-uses increases. These energy end-uses are typically associated with tenants or owners’ activities. In addition, high performance buildings show new issues related to HVAC systems operations. Therefore, it is important to evaluate and improve non-regulatory energy end-uses energy as well as HVAC systems operations efficiencies. We have developed polynomial energy models that can predict energy consumption as a function of building’s activities characteristics and HVAC systems operations factors. We used EnergyPlus software in order to build reliable energy models along with the D-optimum design of experiments method (DOE). Then, we used measurement and verification (M&V) data, associated with probability functions, to determine the associated uncertainty of the calculated energy consumption. Finally, we combine the latter with the polynomial modeling error to calculate the energy consumption global uncertainty, with the goal to identify strategies to reduce it.

▼ The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) provides pavement analysis and performance predictions under various feasible design scenarios. The MEPDG performance predictions for the anticipated climatic and traffic conditions will depend on the values of the input parameters that characterize the pavement materials, layers, design features, and condition. This research focuses on comprehensive sensitivity analyses of flexible pavement performance predictions to MEPDG design inputs under five climatic conditions and three traffic levels. Design inputs evaluated in the analyses include traffic volume, layer thicknesses, material properties, groundwater depth, and others. Correlations among design inputs were considered where appropriate. Both local One-At-a-Time (OAT) sensitivity analyses and global sensitivity analyses (GSA) were performed. Two response surface modeling (RSM) approaches, multivariate linear regressions and artificial neural networks (ANN), were developed to model the GSA results for evaluation of MEPDG input sensitivities across the entire problem domain. The ANN-based RSMs were particularly effective in providing robust and accurate representations of the complex relationships between MEPDG inputs and distress outputs. The design limit normalized sensitivity index (NSI) adopted in this study provides practical interpretation of sensitivity by relating a given percentage change in a MEPDG input to the corresponding percentage change in predicted distress/service life relative to its design limit value. The design inputs most consistently in the highest sensitivity categories across all distresses were the hot mix asphalt (HMA) dynamic modulus master curve, HMA thickness, surface shortwave absorptivity, and HMA Poisson's ratio. Longitudinal and alligator fatigue cracking were also very sensitive to granular base thickness and resilient modulus and subgrade resilient modulus. Additional findings are also provided for each specific pavement type. Advisors/Committee Members: Schwartz, Charles W. (advisor).

▼ In the field of infectious disease epidemiology, the assessment of model robustness outcomes plays a significant role in the identification, reformulation, and evaluation of preparedness strategies aimed at limiting the impact of catastrophic events (pandemics or the deliberate release of biological agents) or used in the management of disease prevention strategies, or employed in the identification and evaluation of control or mitigation measures. The research work in this dissertation focuses on: The comparison and assessment of the role of exponentially distributed waiting times versus the use of generalized non-exponential parametric distributed waiting times of infectious periods on the quantitative and qualitative outcomes generated by Susceptible-Infectious-Removed (SIR) models. Specifically, Gamma distributed infectious periods are considered in the three research projects developed following the applications found in (Bailey 1964, Anderson 1980, Wearing 2005, Feng 2007, Feng 2007, Yan 2008, lloyd 2009, Vergu 2010). i) The first project focuses on the influence of input model parameters, such as the transmission rate, mean and variance of Gamma distributed infectious periods, on disease prevalence, the peak epidemic size and its timing, final epidemic size, epidemic duration and basic reproduction number. Global uncertainty and sensitivity analyses are carried out using a deterministic Susceptible-Infectious-Recovered (SIR) model. The quantitative effect and qualitative relation between input model parameters and outcome variables are established using Latin Hypercube Sampling (LHS) and Partial rank correlation coefficient (PRCC) and Spearman rank correlation coefficient (RCC) sensitivity indices. We learnt that: For relatively low (R0 close to one) to high (mean of R0 equals 15) transmissibility, the variance of the Gamma distribution for the infectious period, input parameter of the deterministic age-of-infection SIR model, is key (statistically significant) on the predictability of the epidemiological variables such as the epidemic duration and the peak size and timing of the prevalence of infectious individuals and therefore, for the predictability these variables, it is preferable to utilize a nonlinear system of Volterra integral equations, rather than a nonlinear system of ordinary differential equations. The predictability of epidemiological variables such as the final epidemic size and the basic reproduction number are unaffected by (or independent of) the variance of the Gamma distribution for the infectious period and therefore for the choice on which type of nonlinear system for the description of the SIR model (VIE's or ODE's) is irrelevant. Although, for practical proposes, with the aim of lowering the complexity and number operations in the numerical methods, a nonlinear system of ordinary differential equations is preferred. The main contribution lies in the development of a model based decision-tool that helps determine when SIR models given in terms of Volterra integral equations are…

▼ Shale gas and oil are playing a significant role in US energy independence by reversing declining production trends. Successful exploration and development of the Eagle Ford Shale Play requires reservoir characterization, recognition of fluid regions, and the application of optimal operational practices in all regions. Using stratigraphic and petrophysical analyses, we evaluated key parameters, of reservoir depth and thickness, fluid composition, reservoir pressure, total organic carbon (TOC), and number of limestone and organic-rich marl interbeds of the Lower Eagle Ford Shale. Spatial statistics were used to identify key reservoir parameters affecting Eagle Ford production. We built reservoir models of various fluid regions and history matched production data. Well deliverability was modeled to optimize oil production rate by designing appropriate operational parameters. From NW to SE, Eagle Ford fluids evolve from oil, to gas condensate and, finally, to dry gas, reflecting greater depth and thermal maturity. From outcrop, the Eagle Ford Shale dips southeastward; depth exceeds 13,000 ft at the Sligo Shelf Margin. We divided Eagle Ford Shale into three layers. The Lower Eagle Ford is present throughout the study area; it is more than 275 ft thick in the Maverick Basin depocenter and thins to less than 50 ft on the northeast. In the Lower Eagle Ford Shale, a strike-elongate trend of high TOC, high average gamma ray values, and low bulk density extends from Maverick Co. northeastward through Guadalupe Co. Both limestone and organic-rich marl beds increase in number from fewer than 2 near outcrop to more than 20 at the shelf margins. Average thicknesses of Lower Eagle Ford limestone and organic-rich marl beds are low (< 5 ft.) in the La Salle – DeWitt trend, coincident with the most productive gas and oil wells. Eagle Ford Shale was divided into 5 production regions in South Texas that coincide with the regional, strike-elongate trends of geologic parameters, which suggests that these parameters significantly impact Eagle Ford Shale production. Eagle Ford Shale production (barrels of oil equivalent, BOE) increases consistently with depth, increases with Lower Eagle Ford thickness (up to 180-ft thickness), and increases with TOC (up to 7%). P values analyses suggest high certainty of the relationship between the production and five reservoir parameters tested in regression models. Multiple good history matches of a gas condensate well suggest significant uncertainties in reservoir parameters. Oil production rate is not sensitive to oil relative permeability for the gas condensate well model. We were unable to match the production history for the volatile oil wells, possibly because gas of lift. Reservoir modeling suggests low bottomhole flowing pressure was the key to optimize cumulative oil production. Concepts and models developed in this study may assist operators in making critical Eagle Ford Shale development decisions; they may be transferable to other shale plays.

▼ A formal framework is developed and implemented in this research for preliminary rotorcraft design using IPPD methodology. All the technical aspects of design are considered including the vehicle engineering, dynamic analysis, stability and control, aerodynamic performance, propulsion, transmission design, weight and balance, noise analysis and economic analysis. The design loop starts with a detailed analysis of requirements. A baseline is selected and upgrade targets are identified depending on the mission requirements. An Overall Evaluation Criterion (OEC) is developed that is used to measure the goodness of the design or to compare the design with competitors. The requirements analysis and baseline upgrade targets lead to the initial sizing and performance estimation of the new design. The digital information is then passed to disciplinary experts. This is where the detailed disciplinary analyses are performed. Information is transferred from one discipline to another as the design loop is iterated. To coordinate all the disciplines in the product development cycle, Multidisciplinary Design Optimization (MDO) techniques e.g. All At Once (AAO) and Collaborative Optimization (CO) are suggested. The methodology is implemented on a Light Turbine Training Helicopter (LTTH) design. Detailed disciplinary analyses are integrated through a common platform for efficient and centralized transfer of design information from one discipline to another in a collaborative manner. Several disciplinary and system level optimization problems are solved. After all the constraints of a multidisciplinary problem have been satisfied and an optimal design has been obtained, it is compared with the initial baseline, using the earlier developed OEC, to measure the level of improvement achieved. Finally a digital preliminary design is proposed. The proposed design methodology provides an automated design framework, facilitates parallel design by removing disciplinary interdependency, current and updated information is made available to all disciplines at all times of the design through a central collaborative repository, overall design time is reduced and an optimized design is achieved.
