本研究旨在探討台灣英文教科書與學生英文作文佳作中，敘述文與說明文中的因果關係使用。因為因果關係在閱讀與寫作中很常見，所以對學生來說，學會如何正確使用因果關係是件極為重要的事。根據李(2003)的研究，她發現因果關係對學生來說是最難學好的因果關係。因此，本研究希望能了解教科書中的敘述文與說明文是如何介紹因果關係給學生。同時，本研究亦希望能得知學生如何在不同文體的英文作文中，使用因果關係。 本研究選用三個版本的高中英文教科書來進行研究，之所以選擇此三版本教科書的原因在於，此三個版本在台灣高中英文課本的市占率最高。而又因為敘述文和說明文在學測和指考的英文作文考試中是最常要測驗學生的文體，因此本研究進一步挑選課本中的敘述文和說明文來進行分析與探討。此外，本研究亦研究民國100年到105年的學測、指考英文作文佳作，舉凡是敘述文和說明文中所使用的因果關係都進行分析與探討。 研究結果顯示在三個版本中，敘述文和說明文的分布無明顯差異。此外，本文發現年級越高的高中生會接觸到愈多的敘述文，但愈少的說明文。研究結果亦顯示文體會影響因果關係的使用情形。相較於敘述文中的因果關係使用，我們發現教科書作者在說明文中使用較多因果關係。 而我們也發現在不同文體中的不同文章結構，因果關係使用的情形不同。在敘述文中，因果關係主要被使用於Complications和Resolutions中。在說明文中，因果關係則主要被使用於Arguments supported by evidence 和Summing up the position中。除此之外，本文亦發現在四類因果連接詞中，Reason和Result這兩類的因果連接詞最常被使用於敘述文和說明文中。 為了清楚看出因果關係，本文針對包含因果關係的句子皆進行了句法、時間及邏輯順序的分析。結果發現幾乎所有因果關係中的時間順序皆與邏輯順序一致。同時，本文亦歸納出教科書中的因果關係的七種使用形式，並提供教科書中的例句來進行討論。 最後，透過學生英文作文佳作的分析，我們發現在因果關係的使用量方面，這群學生與教科書作者相似。而本研究亦歸納出學生在佳作中的四個因果關係誤用的問題。 希望本研究的發現及所提供的建議可供台灣高中英文科教師、教科書作者以及高中生參考。 / The purpose of the study is to investigate the variations of causal relations in narrations and expositions in Taiwan senior high school's English textbooks, and high performance students’compositions. Since causal relations are common in reading and writing, it is important for students to learn to use it. According to Lee (2003), causal relations are the most difficult logical relations for students to master. The present study wants to know how causal relations are introduced to learners in the narrations and expositions from textbooks. Besides, the present study also wants to know how students use causal relations in different genres of compositions. In the study, three series of textbooks are selected for the examination. These three textbooks were chosen as they are commonly used textbooks in Taiwan senior high schools. The selected texts for examination are the texts of two genres: narration and exposition, for these two genres are frequently tested in College Entrance Exams. Moreover, the causal relations in narrations and expositions among the high-scoring essays in years of 2011 to 2016College Entrance Exams were examined as well. The results showed that three series of textbooks in have no significant differences in the distributions of narrations and expositions. Besides, senior high school students expose more narrations but fewer expositions in the higher grades. Furthermore, the result revealed that genres do influence the uses of causal relations, for expositions in the textbooks applied more causal relations than the narrations in the textbooks. Moreover, different usages among different text organizations in both narrations and expositions were found. In the text organizations of narrations, causal relations were mainly used in complications and resolutions.In the text organizations of expositions, causal relations were mainly used in Arguments supported by evidence and Summing up the position. The types of causal relations which are frequently used in textbooks were also found as well. The results showed that Reason and Result type of causal logical connectors were mainly used in both narrations and expositions. Analyses of casual relations’sequences were conducted to clearly see the syntactic sequences, temporal sequences, and logical sequences of the sentences with causal relations. It was found that almost all the causal relations in the textbooks had the temporal sequences equaled to the logical sequences. Moreover, six usages of causal logical connectors were categorized and presented with example sentences. Last but not least, through the analyses of causal relations in students’high-scoring essays, the result showed that high performance students used the similar amounts of causal relations in their compositions with the textbooks’ writers. The present study also categorizes the errors of misusing the causal relations into four problems. It is hoped that this study can provide insights for the senior high school English teachers, textbook publishers, and students to follow.

This diploma thesis deals with optic fiber connectors and their influence on transmissions realized via fiber optics. Optical fibers and lightguides play the key role in telecommunications because of constant demands of higher bandwidth and data rates. Original metalic wires do not meet market requirements and so the fiber optics are more and more being used. There are various types of fibers and there are also many ways of connections. This work deals with demountable way of connection – optical connectors, which have the biggest influence on a total attenuation and route length. Connector has to meet various requirements such as cleannes, quality, mechanical construction and ferrule polishing.

Concluypo enmbargo. / Solicitud de envío manuscrito de artículo científico. / El presente trabajo propone un dispositivo electrónico portátil que, acoplado a un microscopio óptico convencional, pueda capturar una imagen microscópica de la fibra óptica y emita un juicio si el conector se encuentra en un estado de limpieza aceptable o no. Asimismo, mediante reportes de trabajo y usando normas internacionales, evaluar los conectores para que formen parte de una base de datos histórica que aporte a los mantenimientos preventivos de una red. Si bien en la actualidad se tienen soluciones tecnológicas parecidas, estas tienen como gran desventaja el alto costo que implica adquirir uno de estos equipos, desanimando a los operadores optar por este importante equipo. Ingenierilmente, esta propuesta será posible mediante el desarrollo de un algoritmo que procese las imágenes capturadas con el uso de diversas herramientas de procesamiento de imágenes como la binarización, transformada de Hough, algoritmo de Canny, escala de grises y ecualización de imágenes, que, montado sobre un hardware basado en un computador de placa reducida, entregará una evaluación del conector de fibra óptica y un reporte descargable que sirve como documentación del trabajo realizado. Dentro de este contexto, los resultados obtenidos son favorables para una utilización en campo, para llegar a esto se tuvo como como variable de calidad el índice de Kappa Cohen, en el cual se demuestra la alta tasa de coincidencia entre las evaluaciones del equipo y la evaluación de ingenieros expertos. / The present work proposes a portable electronic device that, coupled with a conventional optical microscope, can capture a microscopic image of the optical fiber and emit a judgment if the connector is in an optimal cleaning state or not. Likewise, through reports and using international standards, evaluate the connectors so that can be part of a source of database that contributes to the preventive maintenance of a network. Although similar technological solutions are currently available, these have the great disadvantage of the high cost of acquiring one of this equipment, discouraging operators from opting for this important procedure. Engineeringfully, this proposal will be possible through the development of an algorithm that processes the captured images with the use of various image processing tools such as binarization, Hough transform, Canny algorithm, grayscale and image equalization, which, mounted on a hardware based on a reduced plate computer, it will provide an evaluation of the fiber optic connector and a downloadable report that serves as documentation of the work done. Within this context, the results obtained are favorable for a field use, to achieve this, the Kappa Cohen index was used as a quality variable, which demonstrates the high rate of coincidence between the evaluations of the equipment and the Evaluation of expert engineers. / Tesis

La dynamique des structures assemblées est un sujet de recherche actuel. En particulier, une prédiction correcte de l'amortissement apporté par les liaisons vissés est devenu une condition essentiel pour un certain nombre d'applications, comme par exemple les avions et les véhicules spatiaux. En effet, pour ces applications, l’utilisation de matériaux avec un coefficient d'amortissement plus élevée, comme des matériaux visco-élastiques, est limité par les conditions de fonctionnement.Ces travaux apportent deux contributions principales. La première porte sur la phase de conception et modélisation, avec la création d'un système de connecteurs pour la reproduction des comportements normal et tangentiel d'une liaisons vissée. Cela est accomplie en considérant seulement les données physiques de la liaison et des surfaces en contact.La deuxième contribution concerne l’évaluation des propriétés dynamiques non-linéaires des assemblages. Un set d'outils de post-traitement utilisant le filtre de Kalman est développé pour réaliser une analyse modale non-linéaire pour les types d'essais les plus communs: les essais aux chocs, les essais en balayage sinus, et les essais en sinus aléatoire.Les méthodes développées ont été appliqués et évaluées sur une structure boulonnée réel, en soulignant les avantages et les inconvénients. Notamment, le filtre de Kalman permet une meilleure précision sur les paramétrés identifiés, mais le procédé d’initialisation du filtre est le problème principal. Une automatisation partiel de l’initialisation est prévu, ainsi que des conseils pratiques grâce à l’expérience acquise sur le sujet. / Bolted structures dynamics is an ongoing research topic. In particular, a correct prediction of the damping provided by bolted joints has became an essential requirement for a certain number of applications, such as aircrafts and space vehicles. In fact, for these applications, the use of materials with higher damping coefficients is limited by environmental conditions.This work provides two main contributions. The first one concerns the design and modeling phase, with the creation of a finite element connectors' system, that reproduces the bolted joint normal and tangential behaviors. The latter is accomplished only by taking into account readily available physical data, such as the bolted joint dimensions and the properties of the surfaces in contact. The second contribution regards the evaluation of assembled structures' nonlinear dynamic properties. A set of post-processing tools making use of the Kalman filter is developed to perform a nonlinear modal analysis for the most common types of experimental tests: impact hammer tests, sweep sine tests, and random vibration tests.The developed methods are then applied and evaluated on a real bolted structure, pointing out advantages and drawbacks. In particular, the Kalman filter allows for a higher accuracy in the determination of modal parameters, but the filter initialization is the main problem. A partial automation of the initialization task is provided, together with practical tips thanks to the experience gained on the subject.

Dans le contexte de la montée des préoccupations écologiques, le développement de véhicules de transports routiers s’oriente vers le développement de véhicules moins polluants à entraînement électrique comme les Véhicules Électriques Hybrides (VEHs) et les Véhicules tout Électriques (VEs). Avec l’augmentation des puissances requises et la réduction de l’espace disponible, la gestion thermique devient une préoccupation de plus en plus importante lors du développement des composants embarqués comme les moteurs/générateurs électriques, onduleurs, batteries et faisceaux électriques. Parmi eux, le faisceau électrique de puissance qui est typiquement composé de câbles électriques, de connecteurs et de boîtes de distribution de puissance ne peut être conçu de manière appropriée qu’à la suite d’une analyse thermique, électrique, chimique et mécanique approfondie.Cette thèse est écrite pour contribuer à l’optimisation de la conception électrothermique de faisceaux de câbles par des simulations afin de réduire la quantité de tests expérimentaux nécessaires pour leur développement. Des modèles théoriques pour la prédiction du comportement électrique et thermique de câbles électriques et des faisceaux de câbles sont passés en revue et adaptés aux exigences automobiles. La validation est accomplie en comparant les résultats de simulation avec ceux d’analyses élément finie (FEA) et de données de mesure. Une partie majeure de cette thèse aborde la simulation thermique de câbles électriques de longueur infinie suspendus dans l’air, prenant en compte les dépendances en température des résistances de conducteurs et la non-linéarité du coefficient de transfert thermique total à la surface du câble. L’influence des courants de blindage et de courants arbitraires dans les conducteurs sur la montée en température des câbles électriques est considérée dans des circuits thermiques équivalents et illustré par des exemples pratiques. / In the context of growing ecological concerns, the development of road transport vehicles moves itself toward the development of less polluting vehicles with electric drives such as Hybrid Electric Vehicles (HEVs) and full Electric Vehicles (EVs). With rising power requirements and reducing available space, thermal management is becoming an increasingly important concern during development of on-board vehicle components such as electric motor(s)/generator(s), power inverter(s), battery pack(s) and cable harnesses. Among them, the cable harness which is typically composed of electrical cables, connectors and power distribution boxes can only be designed properly after a detailed thermal, electrical, chemical and mechanical analysis.This thesis is written to contribute to the optimization of the electro-thermal design of cable harnesses through simulations and reduce the amount of experimental testing needed during their development. Theoretical models for the prediction of the electrical and thermal behavior of electric cables and cable harnesses are reviewed and adapted for automotive requirements. Validation is accomplished by comparing simulation results with Finite Element Analysis (FEA) and measurement data. A major part of this thesis addresses the thermal simulation of electrical cables of infinite length installed in air, taking into account the temperature dependencies of conductor resistances and non-linearity of the total heat transfer coefficient at the cable surface. The influence of shielding currents and arbitrary current loads in the conductors on the temperature rises within electric cables is also considered using thermal ladder networks and illustrated by practical examples. Because shielding currents in vehicles are not only caused by induced currents but also by functional electrical currents generated by low-voltage power sources, new theoretical studies and experimental observations for the estimation of these currents as a function of the vehicle electrical architecture and circuit characteristics are presented. A primary finding reveals that keeping the resistance of grounding connections low compared to that of the shielding connections is an appropriate but expensive means for limiting the transfer of functional currents in the shielding circuits. Finally, a complete and modular model for the prediction of transient temperatures along the length of cable harness sections is developed and validated based on the outcomes of all previous findings.

Pattern matching approaches in reverse engineering aim to incorporate domain knowledge and system documentation in the software architecture extraction process, hence provide a user/tool collaborative environment for architectural design recovery. This thesis presents a model and an environment for recovering the high level design of legacy software systems based on user defined architectural patterns and graph matching techniques. In the proposed model, a high-level view of a software system in terms of the system components and their interactions is represented as a query, using a description language. A query is mapped onto a pattern-graph, where a module and its interactions with other modules are represented as a group of graph-nodes and a group of graph-edges, respectively. Interaction constraints can be modeled by the description language as a part of the query. Such a pattern-graph is applied against an entity-relation graph that represents the information extracted from the source code of the software system. An approximate graph matching process performs a series of graph edit operations (i. e. , node/edge insertion/deletion) on the pattern-graph and uses a ranking mechanism based on data mining association to obtain a sub-optimal solution. The obtained solution corresponds to an extracted architecture that complies with the given query. An interactive prototype toolkit implemented as part of this thesis provides an environment for architecture recovery in two levels. First the system is decomposed into a number of subsystems of files. Second each subsystem can be decomposed into a number of modules of functions, datatypes, and variables.
