As the recent financial crisis brought to light, the ability of commercial banks to quantify and better manage risk in their loan portfolios is paramount to their continued success and viability. Assessing, managing, and retaining capital is now a larger issue than ever given this event as well as the advent of the Basel III Accord. Pinnacle Bancorp is a community banking organization headquartered in Omaha, Nebraska with roughly $8.6 billion in assets. The company is also one of the largest agricultural lenders in the country and the largest agricultural lender among traditional community banks. Given the ominous outlook heading into 2016 for agricultural producers from lower projected net incomes and increased borrowing costs following Federal Reserve action on the Fed Funds Rate, many banks worry about the increased likelihood of default for agricultural producers. The objective of this thesis is to determine the adequacy of Pinnacle Bank’s equity capital relative to the agricultural loan portfolio. This process begins by employing binary logit regression in an effort to determine the probability of default for the bank’s agricultural loan portfolio. With default likelihood quantified, efforts are then made to determine the bank’s credit value-at-risk at various solvency levels. These figures are then compared to current capital levels in order to determine the adequacy of bank capital as measured by five key regulatory ratios ultimately imposed by Basel III. Finally, recommendations are made to management as to the adequacy of bank capital relative to the agricultural loan portfolio and any future efforts that need to be made in order to determine and ensure the adequacy of bank capital for the entire loan portfolio.

Texto completoResumen
The dissertation begins with a description of the securitisation process and the subjects involved. In the first part we present some introductory notions about the functioning of the products obtained by the securitization process. In this introductory section, special attention will be paid to the purposes of securitisation transactions.
The aim of the second part of the thesis is to analyse CDOs, which are financial instruments deriving from the securitisation process. Due to their high leverage and complexity, CDOs are among the main culprits of the previous crisis. The next step is to describe the functioning of the CDOs and their risk and performance features. In this part of the thesis, we will present some models used for the evaluation of CDOs and the measurement of their risk.
Subsequently, a class of financial products belonging to the CDO family will be analysed: the CLOs. In particular, we will try to track the evolution of the relationship between CLOs and their underlying assets during the pandemic.
Since leveraged loans are the main underlying of a CLO, we will continue with the description of these products and their origination process. During the preparation of the thesis, we will analyze data from a variety of sources, including the Bloomberg platform, academic articles, and periodic reports of the CRA, as well as studies conducted by regulators to tackle the outbreak of a new crisis.

Texto completoResumen
Cinq crises majeures ont affectées la biodiversité et les activités humaines mènent à une sixième. La disparité, visant à quantifier la diversité morphologique, est une approche pertinente pour comparer ces crises. La disparité a toutefois été rarement appliquée à la biologie de la conservation. Nous étudions, ici, l’impact sur la disparité des ailes d’Odonata (1) de l’artificialisation de l’occupation des sols et (2) de l’extinction de masse Permo-Triassique. Pour quantifier la morphologie alaire, nous avons élaboré un patron de base d’homologies de nervation alaire applicable aux espèces actuelles et fossiles. Nous avons, ensuite, utilisé la morphométrie géométrique et élaboré un set de landmarks et de semi-landmarks optimale. L’impact de l’artificialisation a été étudié sur des sites en Ile-de-France. L’artificialisation et la perte d’espèces n’a pas d’impact significatif sur la disparité, ce qui supporte un scénario d’extinction non-sélective sur la morphologie. Rien n’indique que la morphologie alaire puisse aider à identifier des espèces spécialistes ou généralistes. Aucunes différences significatives n’ont été observées entre la disparité et la diversité du Permien et du Trias. Des morphologies extrêmes perdues durant le Permien ont pu être compensées par de nouvelles morphologies extrêmes durant le Trias. Étant donné la résolution temporelle, les effets de la perte et récupération d’espèces ne peuvent être distingués. Les crises actuelles pourraient être comparables, dans leurs effets, aux extinctions de masses passées. Cependant, les données sur les actuelles devraient être élargies et la résolution de l’échantillonnage fossile affinéeFive major crises have affected biodiversity and human activities are leading to a sixth one. Disparity, aiming at quantifying morphological diversity, might be a relevant approach to compare these crises. Disparity has, however, rarely been applied in conservation biology. Here we investigated the impact on Odonata wingdisparity (1) of land cover artificialization and (2) of the Permo-Triassic mass extinction. To quantify wing morphology, we assessed a basic pattern of wing venation homologies applicable to extant and fossil species. We then used a morphometric geometric approach and elaborated an optimal set of landmarks and sliding semi-landmarks. Impact of artificialization has been investigated on sites in Ile-de-France. Artificialization and loss of species do not significantly impact disparity. This support a scenario of a non-morphologically selective extinction. We did not found evidence that wing morphology might help recognition of specialised or generalist species. No significant differences between disparity and diversity of the Permian and the Triassic were observed. Extreme morphologies lost in the Permian may have been compensated with new extreme morphologies during the Triassic. Given the temporal resolution, effects of species loss and recovery cannot be distinguished. Current crises could be comparable in their effects to past mass extinction. However, data on extant should be broadened to all the species monitored worldwide and resolution of fossil sampling refined

Texto completoResumen
Aujourd'hui la connectivité entre les systèmes se standardise. Il supprime l'intervention humaine et permet aux systèmes distribués d'accomplir des tâches longues et complexes. La SOA est une approche fondée sur le modèle qui s'appuie sur des contrats et qui permet aux systèmes existants de collaborer par échange de messages. De multiples organisations peuvent, automatiser des échanges de services sans risquer leur confidentialité. Cette collaboration est à l'origine des difficultés concernant le test, parce que si il a des échanges entre les différents partenaires, le fonctionnement interne de processus résultant dans l'information échangé est limité à certains partenaires/testeurs. Ceci nous place dans un cadre de tests boîte grise où les systèmes sont des boîtes noires et seulement l'échange de message est visible. C'est pourquoi nous proposons une approche probabiliste en utilisant l'inférence bayésienne pour tester les SOA. Le deuxième défi est leur taille. Etant donné que les systèmes sont connectés de manière lâche en les couplant deux par deux selon les spécifications, une SOA peut contenir un nombre très important de participants et donc une grande taille. La taille des SOA se reflète dans la complexité de l'inférence bayésienne. Cette seconde contrainte pousse à chercher de meilleure solution pour l'inférence bayésienne. Afin de faire face à la taille et la densité de la BN, même pour de petits services architectures, les techniques d'inférence par compilation dirigée par les modèles qui permet la génération rapide de circuits arithmétiques directement à partir du modèle de l'architecture des services et de la suite de tests sont en cours d'élaborationIn present times connectivity between systems becomes more common. It removes human mediation and allows complex distributed systems to autonomously complete long and complex tasks. SOA is a model driven contract based approach that allows legacy systems to collaborate by messages exchange. Collaboration, here, is a key word in the sense that multiple organisation can, with this approach, automate services exchanges between them without putting at risks their confidentiality. This cause to encounter the first difficulty, because if there are exchanges between the different partners, the inner-processes resulting in the exchange information is restricted to some partners and therefor to some of the testers. That put us in a grey-box testing case where the systems are black-boxes and only the message exchange is visible. That is why we propose a probabilistic approach using Bayesian Inference to test the architectures. The second Challenge is the size of the SOA. Since the systems are connected by loosely coupling them two by two according to SOA Specifications, SOA can contain a very important number of participants. In Fact most of the existing SOA are very important in there size. The size of the SOA is reflected in the complexity of the Bayesian inference. This second challenge constraints us to search for better solution for the Bayesian Inference. In order to cope with the size and density of the BN for even small services architectures, techniques of model-driven inference by compilation that allows quick generation of arithmetic circuits directly from the services architecture model and the test suite are being developed

Texto completoResumen
Les infections et maladies hépatiques sont une cause majeure de morbidité et de mortalité. Elles incluent des infections causées par des pathogènes hépatotropiques, comme le parasite Plasmodium, et des maladies d’origine non infectieuse causées notamment par des traitements médicamenteux, telle que la cholestase. L’hépatocyte humain primaire (PHH) est le type cellulaire de choix pour étudier ces infections et pathologies in vitro, mais il est nécessaire de développer de nouveaux modèles de culture plus proches de la physiologie des cellules in vivo et plus pertinents que les modèles 2D. C’est dans ce contexte que s’inscrit mon projet de thèse visant à développer des systèmes de culture en 3D de cellules hépatiques humaines. Les travaux menés ont conduit à la mise en place d’un modèle 3D sphéroïde scaffold-free de PHH viable et plus fonctionnel que le modèle 2D+. Les résultats montrent également que les sphéroïdes de PHH sont un modèle approprié pour la culture du stade hépatique de Plasmodium et suggèrent une meilleure sensibilité de ce modèle pour la prédiction d’activité de molécules antipaludiques. Dans le but d’améliorer la manipulation des sphéroïdes, la magnétisation des sphéroïdes à l’aide de nanoparticules (NS) a été testée. Les NS n’affectent ni la viabilité, ni les fonctions hépatiques des PHH, ni leur susceptibilité à l’infection par Plasmodium. Enfin, un modèle identique avec des cellules HepaRG a été utilisé pour tester une méthode de détection de la cholestase médicamenteuse à l’aide d’une nouvelle sonde fluorescente. Les résultats suggèrent que cette sonde peut être utilisée dans des modèles sphéroïdes pour l’évaluation de l’activité de molécules cholestatiquesLiver infections and diseases are a major cause of morbidity and mortality. They include infections caused by hepatotropic pathogens, such as the Plasmodium parasite, and diseases of non-infectious origin caused in particular by drug treatments, such as cholestasis. The primary human hepatocyte (PHH) is the cell type of choice to study these infections and pathologies in vitro, but it is essential to develop new culture models closer to the physiology of cells in vivo and more relevant than 2D models. In this context, my thesis project aims to develop 3D culture systems for human liver cells. The work allowed to the establishment of a viable 3D spheroid scaffold-free model of PHH more functional than the 2D+ model. The results also demonstrate that PHH spheroids are an appropriate model for the culture of the liver stage of Plasmodium and would be more sensitive to antimalarial molecules. In order to improve the manipulation of spheroids, the magnetization of spheroids using nanoparticles (NS) was tested. NS do not affect the viability or hepatic functions of PHHs or their susceptibility to Plasmodium infection. Finally, an identical model with HepaRG cells was used to test a method for detecting drug induced cholestasis using a new fluorescent probe. The results proved that this probe can be used in spheroid models for the evaluation of the activity of cholestatic molecules

Cette thèse aborde le problème de la synchronisation globale de grand système sur puce (SoC). Il est centré sur l'étude d'une technique de remplacement de la distribution d'horloge classique et d'une communication asynchrone. Il permet la mise en œuvre de circuit synchrone très fiable. Mon projet de thèse vise à étudier et mettre en œuvre un vaste réseau (10x10) de boucle à verrouillage de phase tous numérique (ADPLL), contenant 100 nœuds générant une horloge pour chaque circuit numérique local. Le prototype a été réalisé sur les horloges de génération de silicium dans la gamme de 903-1161 MHz. Elle met en évidence une erreur de phase maximale de moins de 40 ps entre deux horloges dans toutes les zones voisines. Un autre résultat important est l'analyse de l'erreur de phase entre les deux oscillateurs non-voisins dans la distance. En étudiant un prototype FPGA du réseau, on a obtenu que l'erreur de phase maximale à l'état d'équilibre entre un signal d'horloge et le signal de référence est inférieur à trois étapes des étapes de quantification PFD. Afin de valider les performances de la synchronisation dans ASIC, nous avons conçu un circuit d'une erreur de mesure sur la puce d'horloge. Ce circuit a un taux faible de la lecture hors puce (quelques MHz), et une résolution élevée (+ -2,5 ps). Reconfiguration constitue une autre caractéristique intéressante. Nous avons exploré cette fonction et a proposé une nouvelle topologie avec des configurations différentes pour les nœuds sur la frontière et dans le noyau du réseau. Cette topologie présente un avantage en interdisant la propagation des erreurs de phase et de réflexionThis thesis addresses the problem of global synchronization of large system on chip (SoC). It focuses on the study of an alternative clock generation technique to conventional clock distribution and asynchronous communication. It allows implementation of highly reliable synchronous circuit. My PhD project aims to study and implement a large network (10x10) of all digital phase-locked loop (ADPLL), containing 100 nodes generating a clock for each local digital circuitry. The prototype was implemented on silicon generating clocks in the range 903-1161 MHz. It highlights a maximum phase error of less than 40 ps between two clocks in any neighboring zones. Another important result is the analysis of phase error between two non-neighboring oscillators in distance. By studying an FPGA prototype of the network, we obtained that maximum phase error at steady state between any clock signal and the reference signal is less than three steps of the PFD quantification steps. In order to validate the performance of synchronization in ASIC, we designed an on-chip clocking error measurement circuit. This circuit has a low rate for the off-chip readout (several MHz), and a high resolution (+-2.5 ps). Reconfigurability is another attractive feature. We have explored this feature and proposed a novel topology with different configurations for nodes on the border and in the kernel of the network. This topology has an advantage in prohibiting phase error propagation and reflection

Texto completoResumen
L'apprentissage automatique répond au problème du traitement de tâches spécifiques pour une grande variété de données. Ces algorithmes peuvent être simples ou difficiles à mettre en place, et c'est par ailleurs le même constat qui peut être fait pour les données. Les données de faible dimension (2 ou 3 dimensions) avec une représentation intuitive (ex. moyenne du prix des baguette par années) sont plus faciles à interpréter/expliquer pour un humain que les données avec des milliers de dimensions. Pour les données à faible dimension, une donnée aberrantes conduit souvent à un décalage conséquent par rapport aux données normales, mais pour le cas des données à haute dimension, c'est différent. La détection des données aberrantes (ou détection d'anomalie, ou détection de nouveauté) est l'étude des observations singulières pour détecter ce qui est normal et anormal. Différentes familles d'approches peuvent être trouvées dans la littérature sur la détection des aberrations. Elles effectuent une analyse des valeurs aberrantes en détectant les comportements principaux de la majorité des observations. Ainsi, les données qui diffèrent de la distribution normale sont considérées comme bruit ou aberration. Nous nous intéressons à l'application de cette tâche au texte. Malgré les progrès récents dans le traitement du langage naturel il est difficile pour une machine de traiter certains contextes. Par exemple, la phrase "Un sourire est une courbe qui redresse tout" a plusieurs niveaux de compréhension, et une machine peut rencontrer des difficultés pour choisir le bon niveau de lecture. Cette thèse présente l'analyse des valeurs aberrantes de haute dimension, appliquée au texte. Peu de travaux s'intéressent à ce contexte précis et nous introduisons un formalisme dédié. Nous abordons également les méthodes d'ensemble qui sont quasiment inexistantes dans la littérature pour notre contexte. Enfin, nous pouvons voir que l'application de la détection de valeurs aberrantes amène des améliorations sur le résumé de texte automatique par abstraction. Dans nos travaux, nous proposons GenTO, une méthode qui prépare et génère un fractionnement des données dans lequel sont insérées des anomalies et des valeurs aberrantes. Sur la base de cette méthode, nous proposons une évaluation et un benchmark des approches de détection de valeurs aberrantes avec des documents. En outre, l'apprentissage sans supervision conduit souvent les modèles à se fier à certains hyperparamètres. À cet égard, nous explorons l'influence de ce genre de paramètre pour les données textuelles. Alors que le choix d'un seul modèle peut entraîner un biais évident par rapport aux données du monde réel, les méthodes d'ensemble permettent d'atténuer ce problème. Elles sont particulièrement efficaces pour l'analyse des valeurs aberrantes. En effet, la sélection de plusieurs valeurs pour un hyperparamètre peut aider à détecter des valeurs aberrantes fortes. L'importance est alors abordée et peut aider un humain à comprendre la sortie d'un modèle boîte noire. Ainsi, l'interprétabilité des modèles de détection de valeurs aberrantes est remise en question. L'association de modèles complets et de modèles restreints permet d'atténuer l'effet boîte noire de certaines approches. Dans certains cas, la détection des aberrations fait référence à la suppression du bruit ou à la détection des anomalies. Certaines applications peuvent bénéficier de la caractéristique d'une telle tâche. La détection des spams et des fake news en est un exemple, mais nous proposons d'utiliser les approches de détection des aberrations pour l'exploration des signaux faibles dans un projet de marketing (par exemple). Ainsi, nous observons que les modèles de la littérature aident à améliorer les approches de résumé de texte par abstraction, sans supervision. Ceux-ci permettent également de trouver les signaux faibles dans le texteMachine learning answers to the problem of handling dedicated tasks with a wide variety of data. Such algorithms can be either simple or difficult to handle depending of the data. Low dimensional data (2-dimension or 3-dimension) with an intuitive representation (average of baguette price by years) are easier to interpret/explain for a human than data with thousands of dimensions. For low dimensional data, the error leads to a significant shift against normal data, but for the case of high dimensional data it is different. Outlier detection (or anomaly detection, or novelty detection) is the study of outlying observations for detecting what is normal and abnormal. Methods that perform such task are algorithms, methods or models that are based on data distributions. Different families of approaches can be found in the literature of outlier detection, and they are mainly independent of ground truth. They perform outlier analysis by detecting the principal behaviors of majority of observations. Thus, data that differ from normal distribution are considered noise or outlier. We detail the application of outlier detection with text. Despite recent progress in natural language processing, computer still lack profound understanding of human language in absence of information. For instance, the sentence "A smile is a curve that set everything straight" has several levels of understanding and a machine can encounter hardship to chose the right level of lecture. This thesis presents the analysis of high-dimensional outliers, applied to text. Recent advances in anomaly detection and outlier detection are not significantly represented with text data and we propose to highlight the main differences with high-dimensional outliers. We also approach ensemble methods that are nearly nonexistent in the literature for our context. Finally, an application of outlier detection for elevate results on abstractive summarization is conducted. We propose GenTO, a method that prepares and generates split of data in which anomalies and outliers are inserted. Based on this method, evaluation and benchmark of outlier detection approaches is proposed with documents. The proposed taxonomy allow to identify difficult and hierarchised outliers that the literature tackles without knowing. Also, learning without supervision often leads models to rely in some hyperparameter. For instance, Local Outlier Factor relies to the k-nearest neighbors for computing the local density. Thus, choosing the right value for k is crucial. In this regard, we explore the influence of such parameter for text data. While choosing one model can leads to obvious bias against real-world data, ensemble methods allow to mitigate such problem. They are particularly efficient with outlier analysis. Indeed, the selection of several values for one hyperparameter can help to detect strong outliers.Importance is then tackled and can help a human to understand the output of black box model. Thus, the interpretability of outlier detection models is questioned. We find that for numerous dataset, a low number of features can be selected as oracle. The association of complete models and restrained models helps to mitigate the black-box effect of some approaches. In some cases, outlier detection refers to noise removal or anomaly detection. Some applications can benefit from the characteristic of such task. Mail spam detection and fake news detection are one example, but we propose to use outlier detection approaches for weak signal exploration in marketing project. Thus, we find that the model of the literature help to improve unsupervised abstractive summarization, and also to find weak signals in text

Dans cette thèse, nous développons de nouvelles méthodes et algorithmes pour générer des résumés personnalisés de critiques de films, basés sur les aspects, pour un utilisateur donné. Le premier problème que nous abordons consiste à extraire un ensemble de mots liés à un aspect des critiques de films. Notre évaluation montre que notre méthode est capable d'extraire même des termes impopulaires qui représentent un aspect, tels que des termes composés ou des abréviations. Nous étudions ensuite le problème de l'annotation des phrases avec des aspects et proposons une nouvelle méthode qui annote les phrases en se basant sur une similitude entre la signature d'aspect et les termes de la phrase. Le troisième problème que nous abordons est la génération de résumés personnalisés, basés sur les aspects. Nous proposons un algorithme d'optimisation pour maximiser la couverture des aspects qui intéressent l'utilisateur et la représentativité des phrases dans le résumé sous réserve de contraintes de longueur et de similarité. Enfin, nous réalisons trois études d’utilisateur qui montrent que l’approche que nous proposons est plus performante que la méthode de pointe en matière de génération de résumésOnline reviewing websites help users decide what to buy or places to go. These platforms allow users to express their opinions using numerical ratings as well as textual comments. The numerical ratings give a coarse idea of the service. On the other hand, textual comments give full details which is tedious for users to read. In this dissertation, we develop novel methods and algorithms to generate personalized, aspect-based summaries of movie reviews for a given user. The first problem we tackle is extracting a set of related words to an aspect from movie reviews. Our evaluation shows that our method is able to extract even unpopular terms that represent an aspect, such as compound terms or abbreviations, as opposed to the methods from the related work. We then study the problem of annotating sentences with aspects, and propose a new method that annotates sentences based on a similarity between the aspect signature and the terms in the sentence. The third problem we tackle is the generation of personalized, aspect-based summaries. We propose an optimization algorithm to maximize the coverage of the aspects the user is interested in and the representativeness of sentences in the summary subject to a length and similarity constraints. Finally, we perform three user studies that show that the approach we propose outperforms the state of art method for generating summaries

Texto completoResumen
Fondée en réaction aux conventions immobilistes et ternes de la Royal Academy, et annonçant des mouvements guidés par une recherche de la seule beauté plastique, la Confrérie Préraphaélite est souvent perçue comme une longue rêverie nostalgique aux contours imprécis. Si son engagement politique permet à William Morris d’échapper à cette catégorisation, Dante Gabriel Rossetti et ses disciples sont habituellement associés à une esthétique passéiste. Prenant le contre-pied de cette lecture, cette recherche s’intéresse à la dimension politique de la Confrérie, et aux enjeux de son engagement philosophique et idéologique. Cette étude d’un corpus poétique et pictural représentatif des Préraphaélites mêle à une perspective culturaliste et historiciste l’aspect esthétique et formel de leur art, pour en faire ressortir les attitudes politiques. En mettant les poèmes et les tableaux en regard de textes théoriques du XIXe siècle et en les lisant au prisme de théories sur la modernité, l’antimodernité, et l’altermodernité, elle exploite l’idée que la faille, représentation du décrochement et du discontinu autant que principe actif de création, permet l’ouverture d’une mise au défi permanente de l’idéologie dominante et la mise en place d’une alternative à la subversion, faisant des Préraphaélites les artisans d’une révolution tranquille destinée à transformer l’art et la société victorienne en profondeurIn reaction to a dull, never-changing Royal Academy, and announcing movements focused on sheer aesthetic beauty, the Pre-Raphaelite Brotherhood is often seen as wrapped in a long, hazy, melancholy reverie. William Morris’s political commitment spares him such labelling, but Dante Gabriel Rossetti and his disciples are often associated with past-obsessed aesthetics. Taking a stand against such a bias, this dissertation emphasises the political aspects of their work, and the scope of their philosophical and ideological commitments. By interweaving a cultural and historicist perspective with the formal and aesthetic sides of their art, this study of a representative set of Pre-Raphaelite paintings and poems seeks to identify the political attitudes underlying their art. Through the prisms of 19th century theoretical texts and reflections by thinkers of modernity, counter-modernity, and alter-modernity, this analysis probes the idea that rifts and faultlines represent both displacements and a creative principle, while simultaneously opening the way to a permanent challenging of dominant ideology and offering an alternative to subversion. The artistic twist on the faultline concept makes the Pre-Raphaelites craftsmen of a quiet revolution, meant to effect a deep transformation of Victorian society and art

Le droit international privé est éprouvé par les droits fondamentaux. Les données à partir desquelles la discipline a été pensée ont d’abord évolué. Les droits de l’homme créent une connexion entre les ordres juridiques étatiques et protègent la mobilité internationale des personnes. Si cette évolution ne remet pas en cause l’existence du problème de droit international privé, force est d’admettre que les droits fondamentaux modifient aujourd’hui son analyse. Tandis que les conflits d’ordres juridiques sont transformés en conflit de valeurs, la hiérarchie des intérêts du droit international privé est remplacée par leur mise en balance. Les solutions de droit international privé sont, ainsi, perturbées par l’application contentieuse des droits fondamentaux. La proportionnalité est plus précisément à l’origine de cette perturbation. Technique de réalisation des droits de l’homme, la proportionnalité a une incidence inégale sur la discipline. Si le contrôle de proportionnalité épargne ses méthodes, il bouleverse en revanche ses solutions. Les Cours européennes ont tendance à privilégier la continuité des situations juridiques sur la défense de la cohésion interne. Aussi pressent-elles le droit international privé à libéraliser ses solutions. L’application contentieuse des droits fondamentaux doit, dès lors, être rationalisée pour préserver l’autorité et la prévisibilité des solutions du conflit de lois et de juridictions. C’est en dissociant l’application des droits de l’homme de l’exception d’ordre public international et en corrigeant la mise en œuvre du contrôle de proportionnalité que l’équilibre du droit international privé pourrait, nous semble-t-il, se reconstruireFundamental rights put private international law to the test. First, the context in which private international law operates has evolved. Fundamental rights have created a better, closer, intertwining of the separate state legal orders and have achieved a higher protection for the persons as they experience international mobility. If this evolution does not threaten, as such, the existence of private international law, it must be acknowledged that fundamental rights modify its analysis. Whereas the conflicts between legal orders are transformed into conflicts between values, the hierarchy of interests protected by private international law is replaced by a balancing of these interests. The solutions of private international law are thus disrupted by the enforcement of fundamental rights through litigation. Proportionality is at the source of this disruption. Being a case by case technique of enforcement of fundamental rights, the influence of the proportionality test on private international is uneven. If the proportionality test is found to be overall indifferent to the methods of private international law, its main impact is on the solutions of PIL. The European courts are indeed prone to favour the continuity in the legal situations of the persons, over the defence of the internal cohesion of the state legal orders. As a consequence, private international law is invited to reach liberal solutions. The enforcement of fundamental rights through litigation must hence be clarified so as to maintain a mesure of authority and predictability of the solutions of the rules of conflict of laws, international jurisdiction and recognition of foreign judgements. It is, on the one hand, by methodologically dissociating the enforcement of fundamental rights from the public policy exception and, on the other hand, through an amendment to the proportionality test, that the balance of private international may hopefully be restored

Using non-financial firm as sample from 2002 to 2013, this research utilizes the Ordinary Least Squares model (OLS) to analyze how the collateral affects the loan spread and nonperformance in lending market in Taiwan. We examine collateral on the loan spread and nonperformance, then we limit sample to pledged loans and distinguish collateral into liquid and illiquid. And we also divide collateral into 14 different types. The empirical evidence shows that collateral is associated with higher loan spread and nonperformance. The result of liquid and illiquid collateral is consistent with the empirical of collateral. And individual collateral types show different results. Most significant result shows that collateral types are associated with higher loan spread and nonperformance.

Due to the turmoil of credit card default in 2005, most of financial institutions have became very strict in offering the unsecured fiduciary loan and change to focus on the secured house mortgage loan. However, the overheating competition in the lending market has substantially decreased the interest spreads and consequentially reduced the profits earned from lending activities. After the loans are originated, the banks bear all kinds of risks, such as interest rate deduction, loan contract amendment, credit amount increase, prepayment, and default. Among the abovementioned risks, prepayment and default account for the greatest risks to the lenders. Therefore, this study will explore the important factors influencing both prepayment and default. This study adopts the logistic regression model to sort out the factors influencing prepayment and default as follows: the borrower’s personal factors (e.g., gender, age, marriage status, source of payment, guarantor, origination of loans), loan contracts factors (e.g., loans period, loan amount, interest rate, grace period, recurring use), and contract content factors (e.g., loan multiplier, loan purpose). This study will show the relationship between the aforementioned determinants and both prepayment and loan default. The empirical results show that age, marriage status, source of payment, interest rate, grace period, recurring use and loan multiplier will influence the loan default. Besides, the guarantor, origination of loans, loan amount, interest rate, grace period, and recurring use will influence the prepayment.

According to the data of the Ministry of finance, the amount of the non-performing loan increased to 5,280.7 hundred million, the rate was up to7.58 % till 2002.The serious problem made the assets of the bank become worse and worse. The domestic banks’ non-performing rate has increased due to two reasons. One is the problem of unemployed, the other is the loan which the loan department to personal or harmfully companies. The unemployed rate must be solved by the government’s policies. As for the problem of the bad debt, they usually use the principles of 5C and 5P to estimate the customer of the Credit Granting, but it is not really work. Because the Credit Granting Decision depend on the collection data and with the subject judgement of psychological to decide the customer Credit Granting and loan decision. Therefore, this essay prepare to adopt the Anchoring and Adjustment Heuristics of the Psychological Decision Theory. To test the loaner when making some Credit Granting Decisions whether or not the debt happened is due to the bias. The results of our study were： 1、When subjects estimating numbers of bed debts, they would be affect by the anchoring effect and the size of anchor. 2、When subjects evaluating risk informations, they would be affected by the anchoring effect. 3、When subjects referencing risk informations to criterion credit investigation scores, they would be affected by the anchoring effect. 4、When subjects evaluating prior probabilities, they would not base on general probability theory, they usually be affected by the anchoring effect. 5、When subjects calculating prior probabilities, they would not be affected by the number of events, but will be affected by the style of events describing.

UAV is one of popular product in aerospace. Many countries have made self’s UAV for many years ago. The UAV, which was used on scopes of military, research and rescue etc.. Power section is the most important for UAV creating. When we are selecting UAV’s engine, we must to analyze demand, which like altitude, velocity ,task requirement and the other factors. After we decide UAV’s power section, the propeller is preceded only by engine. Now, the most of engine vendors will recommend many appropriate propeller for engine in the commercial market. But the vendor sometimes does not show individual performance of engine’s propeller test. So designer must test and analyze the propeller with engine before install on UAV. This master thesis will focus on power calculation. The engine is Rotax914 which will match to Warpdrive propeller. Rotax914 is one of the most popular engine in light aircraft. The most famous UAV use Rotax914 engine which is MQ-1 made in USA. It is a very common engine ,so this thesis will supply an useful reference.

Using triaxial tests, before the failure of specimens, the deviator stress was fixed and the cyclic mean stress was applied to study the influence of creep on cemented sand. Compared with the natural geological materials with anisotropy, cemented sand is a synthetic material with homogeneous and uniform advantages, so the error caused by the test is small. Due to the material composition, cemented sand has the property of being weakened by water, so the pore water pressure is not added during the test. It has been found through experiments that the creep test with the cyclic mean stress has a shorter duration than the conventional creep test with only fixed deviator stress, and the volumetric strain of the two creep test is similar. Therefore, in order to shorten the time of observing the material''s creep behavior, a creep test method with a fixed deviator stress and cyclic mean stress is selected for research. The test results show that the axial strain accumulation, the axial strain rate, and the strength after creep of cemented sand, both are positively correlated with the creep initial mean stress, under the same creep time and creep initial stress ratio. The test results also show that the axial strain accumulation and the axial strain rate of cemented sand are positively correlated with the creep initial stress ratio, and the strength after creep of cemented sand is negatively correlated with the creep initial stress ratio, under the same creep time and creep initial mean stress. Under the same creep initial stress ratio, cemented sand with the same amplitude and period for triaxial creep test. According to the test results, the number of cycles to failure, the axial strain accumulation and the axial strain rate in the creep second stage of cemented sand are positively correlated with the creep initial mean stress. In this study, cemented sand was used to conduct the creep test. After testing, it was found that the volumetric strain case of the cyclic mean stress creep test is similar to the conventional creep test with only fixed deviator stress and is relatively short. Therefore, the cyclic creep test may be used to replace the traditional creep test to shorten the time for studying the material''s creep behavior. Although the creep behavior discussed in this study is not quite comprehensive due to the limitations of measuring instruments., it may be a possibility to replace the traditional creep test with a cyclic creep test. In addition, it is also observed that the creep initial stress ratio, and the creep initial mean stress both have an effect on the creep behavior of the cemented sand.

In recent years, the rise of the Internet and smart vehicles, everyone can often post their own messages and posts on the community platform, in this way to express their opinions and ideas. For enterprises, because of these messages behind the scene can be seen the views of consumers, so these text messages become an important decision-making basis for enterprises. How to interpret and infer these words becomes an important issue. In recent years, tourism is one of the industries that have strong demand for text analysis, because more and more people will turn their travel experience into texts published on social platforms, such as tourist blogs, and travel notes, but how to have a systematic interpretation of these words requires techniques based on text analysis. Commonly used text analysis techniques include content analysis, word exploration and sentiment analysis. The core of these techniques is to summarize and sort the words and build the fonts. Quantification, however, in the past related research, only the keyword sentences for the message content of the tourists were counted or the positive and negative emotion analysis was performed. The text was interpreted only from a single angle, and the important meaning behind the words was usually ignored. Therefore, this study will use the technique of text analysis combined with the travel experience related scale to explain the meaning behind the guest message. This study will use Sentiment Analysis, based on the Memorable Tourism Experience Scale (MTE), and integrate AFINN sentiment dictionary and unforgettable tourism experience feature keyword vocabulary to design an unforgettable tourism experience measurement facet. Through the results of the online questionnaire, verify the unforgettable travel experience. The traditional scores and the qualitative texts have a consistent result of the emotional scores after systematic analysis. That is, it is finally known that the traditional questionnaire method and the emotional analysis method are used for memorable. The analysis of the tourism experience can achieve the same effect.

In situ chemical oxidation (ISCO) is a widely used technique for treating soil and groundwater contaminated with chlorinated organic solvents such as trichloroethylene (TCE). The sodium persulfate (SPS) is a promising ISCO oxidant. The effective contact between oxidant and contaminant, especially within a low permeability zones (LPZs) in the heterogeneous aquifer, is also a challenge issue in the ISCO application. This study attempted to use xanthan gum (XG) mixing with gelatin (G) to prepare a gel liquid with a low initial viscosity (＜ 15 cP) and a high viscosity > 700 cP upon gelation. This gel can be incorporated with SPS to form SPS sustained-release gel (SPS SR-Gel). This gel containing SPS oxidant can be injected and transported to LPZs, thereby increasing the contact between SPS and contaminants. The results of gel properties indicated that the viscosity of the xanthan gum was about 25 cP. When the xanthan gum was mixed with gelatin, the difference of transition temperatures between xanthan gum and gelatin resulted in structural changes and then achieved gelation. The objectives of this study were to investigate gel transportation and oxidant release behavior of SPS SR-Gel. Additionally, the potential of SPS SR-Gel in treating TCE in free phase or sorbed phase in LPZs was evaluated in one-dimensional column. Observation of blue-dyed gel transportation in the column revealed that after the gelation formed, the gel stayed at the location where it was gelated. SPS released rapidly at a relatively high water flushing velocity (0.392 cm/min) but SPS was steadily released at a rate of 0.26±0.22 mg SPS/min under a water velocity of 0.019 cm/min. Regardless of TCE mass of 0.493 g or 0.085 g contained silty soils within the column treated by SPS SR-Gel, the accumulative mass of effluent TCE and TCE mineralized was accounted about 50% of its initial mass. The mass of SPS released was accounted for about 50% of its initial mass. These preliminary results indicated that the SPS SR-Gel exhibited the potential to sustained release of SPS for effectively treating TCE contamination.

Background: Cognitive function and physical fitness testing should be performed earlier in the adulthood health examination in order to early detecting and preventing disabilities. Purpose: The purpose of the study is to examine the validity and reliability of a newly developed automatic ORBBEC-based physical fitness test and voice response cognitive assessment system for community-dwelling middle-aged and older adults. Method: Both the traditional testing and newly developed automatic fitness testing and cognitive assessment system were performed in 30 subjects. The inter-rater reliability, test-retest reliability and concurrent validity were analyzed by intraclass correlation coefficient (ICC) and Pearson Correlation coefficienct (r). Results: The inter-rater reliability (ICC>0.800) and the validity (r>0.776) of fitness testing system showed excellent correlations between traditional method and automatic system in older people. Most of the items in cognitive assessment system showed significant validity and test-retest reliability (r>0.648, ICC>0.560). Conclusion: The newly developed automatic ORBBEC-based physical fitness test and voice response cognitive assessment system showed good validity and reliability in most of the test items in both middle-aged and older adults. With some amendments of those low validity test items, the time- and manpower-saving automatic system would be helpful in assessing fitness and cognitive function.

The development of the next generation electron devices will be flexible because the requirements of miniaturization in structural size, light weight, and multi-functions. However, the portable electron devices are usually subjected a dropping load because the careless implantation by human being. Thus, the investigation and analysis of dropping test utilized in electron devices and flexible displays become a major mechanical reliability concern of the foregoing architectures. For these reasons, this study focused on the development of simulation methodology for dropping test is presented to estimate the impact of dropping load on the flexible displays. The structure design and material selection is optimized to enhance the corresponding mechanical reliability of flexible display. Due to the flexible display will be failed easily by the impact, this study also present a stress buffer layer for flexible display. The stress buffer layer can release the impact and increase the reliability of flexible display. To achieve the best design for release the impact, the metal foil’s thickness and buffer layer’s Young’s modulus in stress buffer layer is also considered for the parameterization design. The simulated results is further verified as compared with the actual experiment results so as to endure the accuracy of simulation. According to the simulation results, the proposed estimated results of flexible display characteristics would be beneficial to the designer or maker with the field of flexible displays when developing a more useful and comfortable flexible electronic products.

The thesis developed a screening test for perioperative anaphylaxis (PA) using electrochemical nanostructured immunosensor. The electrochemical immunosensor had advantages of simple, fast, sensitive and low-cost. The nanostructured sputtering gold nanoparticles (GNPs) with modified self-assembled monolayers (SAMs) can enhance the sensitivity and simplify the process using electrochemical impedance spectroscopy (EIS) method. Basophils were stimulated with neuromuscular blocking agents (NMBA) and the released histamine was detected as indicators of PA. Standard solutions were used to calibrate nanostructured sensors. The concentration of histamine from 0.1ng/ml to 10ng/ml was measured by EIS with a linear regression line of y = 5070ln(x) + 12633 with error R2=0.9565. Released histamines in real plasma sample stimulated by NMBA, rocuronium, atracurium, cisatracurium, were also measured. Reaction time for plasma stimulated by NMBA was also studied. The results were compared to basophil activation test (BAT) and skin tests (ST), experimental result showed that electrochemical nanostructured immunosensor had similar results with skin test.
