Aplicação do algoritmo genético de Chu-Beasley especializado no ajuste dos parâmetros dos controladores suplementares e dispositivo FACTS IPFC /

Fortes, Elenilson de Vargas January 2016 (has links)
Orientador: Percival Bueno de Araujo / Resumo: Este trabalho apresenta o Algoritmo Genético de Chu-Beasley Especializado para realizar o ajuste coordenado dos parâmetros de controladores Proporcional-Integral e suplementares de amortecimento (Estabilizadores de Sistemas de Potência e Interline Power Flow Controller - Power Oscillation Damping) em sistemas elétricos de potência multimáquinas. O objetivo principal deste trabalho é inserir amortecimento adicional às oscilações eletromecânicas de baixa frequência classificadas como local e interárea. Para representar o sistema, é utilizado o Modelo de Sensibilidade de Corrente. Desse modo, todos os seus dispositivos e componentes foram modelados por injeção de corrente e, portanto, um novo modelo de injeção de corrente para o Interline Power Flow Controller é apresentado. Três sistemas teste foram utilizados nas simulações realizadas neste trabalho, sendo: Simétrico de Duas Áreas, New England e o Sul Brasileiro Reduzido. O desempenho da metodologia proposta (Algoritmo Genético de Chu-Beasley Especializado), no que concerne ao ajuste dos parâmetros dos controladores, foi comparado a outros dois algoritmos bastantes difundidos na literatura: Particle Swarm Optimization e o Algoritmo Genético com Elitismo. Os resultados demonstraram que o algoritmo Genético de Chu-Beasley Especializado foi mais eficiente que as demais técnicas apresentadas, obtendo soluções robustas quando variações de cargas foram consideradas, sendo, portanto, credenciado como ferramenta no estudo da análise d...

La reconversion des anciens hôpitaux, un enjeu pour les centres hospitaliers et les métropoles françaises : expériences comparées à Lyon, Marseille, Montpellier, Paris, Poitiers et Saint-Etienne / The redevelopment of former hospitals, a major issue for public healthcare establishments and metropolises : compared experiences in Lyon, Marseille, Montpellier, Paris, Poitiers and Saint-Etienne

Pétillot, Anne 31 January 2013 (has links)
Depuis vingt-cinq ans, les centres hospitaliers universitaires français connaissent un mouvement sans précédent de regroupement de leurs activités médicales qui les conduit à désaffecter puis à vendre de nombreux sites hospitaliers.La reconversion de ces anciens hôpitaux est un enjeu majeur pour les établissements publics de santé comme pour les collectivités. Les premiers doivent valoriser au mieux leur patrimoine pour financer la modernisation ou la construction des hôpitaux en activité. Les secondes doivent réussir la transformation des grands enclos ainsi libérés et garantir leur bon usage au bénéfice des populations des métropoles concernées.Après avoir mis en lumière les mécanismes de décision et de gestion propres à chacun des acteurs et souligné la diversité des attentes, le travail s’appuyant sur l’analyse comparée de neuf opérations situées à Lyon, Marseille, Montpellier, Paris, Poitiers et Saint-Etienne, s’attache à identifier les potentiels de développement urbain des anciens hôpitaux, leurs valeurs parfois paradoxales, enfin le rôle de l’établissement de santé, de la ville ou de l’agglomération, ainsi que de la société civile dans la production des opérations.Cette approche croisée et quantifiée conduit à esquisser des axes de travail d’intérêt général. Ceux-ci concernent aussi bien les centres hospitaliers dans la préparation et la conduite du processus de désaffectation et de cession que les collectivités dans la définition des besoins et la mise en œuvre des opérations. Est mis en avant pour finir le rôle de l’Etat pour réduire les contradictions, aider à la juste évaluation des biens et accélérer les processus de transformation urbaine. / In the past 25 years, French teaching hospitals have had to concentrate their activities as never before, leading to many hospital sites being closed down and sold off. The redevelopment of these former hospitals is a major issue for public healthcare establishments and local authorities alike. The former need to enhance their property to raise funds to modernise and build hospitals in use. The latter need to oversee the transformation of the huge complexes newly available and ensure they benefit the inhabitants of the cities involved. After examining the decision-making process and management implemented by all players and highlighting the sheer diversity of expectations, a comparative analysis of nine operations located in Lyon, Marseille, Montpellier, Paris, Poitiers and Saint-Etienne pinpoints potential urban development of former hospitals, their sometimes contradictory values and the role of the healthcare establishment, city council and civil society in the production of the operations. This comparative approach, backed with figures, leads to some general-interest suggestions. These involve not only the hospitals which prepare and lead the closing process and transfer, but also the local authorities which define requirements and implement operations. Finally, the government’s role of reducing contradictions, helping to properly assess the property and speeding up the processes of urban transformation is also covered.

Temps et mémoire dans l’oeuvre de CHU T’ien-hsin, une quête de la subjectivité insulaire dans le roman taïwanais après 1987 / Time and Memory in the Work of CHU T’ien-hsin : Searching for an Insular Subjectivity in the Taiwanese Novel after 1987

Secher, Fang-hwey 28 September 2012 (has links)
La thèse s’intéresse au rapport entre temps et mémoire dans la littérature taïwanaise au lendemain de la levée de la loi martiale en 1987. Elle examine plus particulièrement la façon par laquelle la littérature reconfigure son époque comme un espace-temps spécifique. Le roman, genre peu codifié et donc caméléon, et qui s'enracine dans ce souci de mémoire et d'histoire, a fortement marqué la première décennie d'après 1987. L'œuvre de la romancière Chu T'ien-hsin, qui a pour thème central la mémoire, apparaît comme particulièrement représentative du foisonnement de la création romanesque d’après 1987 à Taïwan. C'est à partir de cette œuvre que l'on s'interroge d'une part sur ce vers quoi le désir, voire l'obsession, de raconter le passé pointe et d'autre part comment cette littérature, à son tour, réinvente sa propre mémoire. Dans une tentative d'éclairer la question de la mémoire et de l'identité qui hante une société en voie de mutation, ce travail s'articule autour des nombreux aspects de la mémoire, du temps et des formes qui y sont relatives. Grâce à cette articulation, l'analyse présente les formes de politisation, mais également de dépolitisation et d'a-politisation, qui émergent sur la scène littéraire contemporaine à Taïwan. L'analyse rend également compte de la manière dont ces formes sont en grande partie associées aux tourments et mutations de l'histoire. En cherchant à concilier l'analyse des conditions sociales de la production littéraire et l’étude des formes élémentaires de l'écriture, ce travail se fonde sur une double approche linguistique et culturelle de la traduction. Dans ce cadre, il est dès lors possible d'envisager une stratégie de la frontière qui permet de basculer entre deux cultures différentes dans le souci de proposer une lumière sur la littérature taïwanaise dans le contexte intellectuel français. / The dissertation focuses on the relation between time and memory in Taiwanese literature in the aftermath of the lifting of the martial law in 1987. It further examines how literature reconfigures its epoch into a specific space-time. The concern for memory and history is deeply rooted in the novel, a chameleon-like genre with few codes which has made a big impact in Taiwan in the first decade after 1987. The work of female novelist Chu T'ien-hsin, in which memory is the central theme, is representative of the creative expansion of the novel in Taiwan after 1987. Taking on an analysis of her novels, the dissertation interrogates on the one hand what the desire, or even the obsession, to relate the past points to, and on the other hand, how in turn, this literature reinvents its own memory. In an attempt to enlighten questions related to memory and identity which haunt a society in mutation, the dissertation is articulated around the many aspects of memory, time and their related forms. Through this articulation, the analysis presents the forms of politicisation, as well as the forms of depoliticisation and a-politicisation, which have emerged on the contemporary scene of literature in Taiwan. The analysis further presents how these forms are mostly associated with the torments and mutations of history. With the aim of accommodating the analysis of the social conditions of literary production with the study of the elementary forms of writing, the research is based on a double approach associating linguistic and cultural translation. It is then possible to consider within this framework a strategy of the border which allows to swing over between two different cultures, offering to shed a light of Taiwanese literature within the French intellectual context.

Optimalizace interferencí v celulárních komunikačních systémech / Interference Optimization in Cellular Communication Systems

Kassem, Edward January 2019 (has links)
Tato práce je rozdělena do šesti kapitol. První kapitola vysvětluje rozdíly mezi fyzickou vrstvou uplinků systémů LTE a LTE Advanced, zkoumá charakteristiky kanálu komunikace D2D v rámci sítě LTE Advanced, a navrhuje mechanismy optimalizace interferencí. Rovněž je v práci prezentována struktura softwarově definované rádiové platformy, která může být využita pro vyhodnocení rádiových kanálů. Druhá kapitola hodnotí a porovnává výkony uplinkové části fyzické vrstvy systému LTE a LTE Advanced. V prostředí MATLAB je implementována struktura LTE Advanced vysílače a přijímače se všemi stupni zpracování signálu. Generované signály obou výše uvedených systémů jsou přenášeny přes různé modely kanálu ITU-R. Byly používány různé techniky odhadu kanálů a detekce signálu pro obnovení vysílaného signálu. Výsledky jsou prezentovány formou křivek BER a křivek datové prostupnosti. Třetí kapitola navrhuje způsob opakování frekvencí v celulární síti (frequency-reuse) se třemi úrovněmi výkonu, který se využívá jako typ pokročilé metody snižování interferencí. Jsou ukázány normalizované kapacitní hustoty buněk a jejich podoblastí se třemi různými případy distribuce uživatelů uvnitř buněk. Je zobrazena korelace mezi celkovou kapacitou a poloměrem každého regionu. Dosažené výsledky navrhovaného schématu jsou porovnávány s tradiční technikou opakovaného použití frekvence (Reuse-3). Čtvrtá kapitola se zabývá výzkumem alternativní metody optimalizace interferencí. Bylo provedeno ověření kooperačních metod snímání rádiového spektra ve čtyřech různých reálných prostředích: venkovní-interiérové, vnitřní-venkovní, venkovní-vnitřní a venkovní-venkovní. Navržený systém je testován pomocí zařízení Universal Software Radio Peripheral (USRP) a obsahuje dva typy detektorů; energetický detektor a statistický detektor založený na Kolmogorově-Smirnovově testu, které byly implementovány na přijímací straně. Jedním z hlavních požadavků komunikace D2D je znalost charakteristik impulzních odezev rádiového kanálu. Pátá kapitola proto představuje metodu měření kanálu pomocí Zadoff-Chu sekvencí ve frekvenční oblasti jako alternativní techniku k měření kanálu v časové nebo frekvenční doméně. Pomocí navržené metody se základní charakteristiky kanálu, jako je časové rozšíření kanálu (RMS delay spread, mean excess delay), útlum šířením a koherenční šířka pásma extrahují v (až 20x) kratším čase ve srovnání s klasickou metodou měření kanálu ve frekvenční doméně. Jsou také zkoumány charakteristiky venkovních statických rádiových kanálů na vzdálenost několika kilometrů pro pásma UHF a SHF s ko-polarizovanou horizontální a vertikální konfigurací antény. Šestá kapitola uzavírá tezi a shrnuje závěry.

論王逸《楚辭章句》的形成. / Study of the formation of Wang Yi's Chuci Zhangju / CUHK electronic theses & dissertations collection / Lun Wang Yi "Chu ci zhang ju" de xing cheng.

January 2010 (has links)
Chuci Zhangju was compiled by Wang Yi (ca.90--ca.158) in the Eastern Han Dynasty(25--220) as an agglomeration of Chuci studies since Qin and Han Dynasties. Chuci Zhangju gathered QuYuan (ca.343--ca.277BC) and other authors' work since the Warring States period and its annotation style---Zhangjuti has been receiving high praise. / On the modern Chuci research, Chuci Zhangju is generally viewed as a mere ancillary annotation, while compared to canonical Chuci. As a result, there is no specialized work focus on Chuci Zhangju. Only scattered academic works are found, and their core concerns are doctrine of canonical texts and literary commentaries, while explanations of words and textual criticism were included sometimes. As a lack of comprehensive analysis of Chuci Zhanju is observed, my following research is carried out in four parts, including textual, annotation, the order of arrangement and interpretation analysis. / This thesis is divided into seven chapters. Chapter One is the introduction, a brief review of Wang Yi's life story and compositions, probing into the motives of Wang Yi's Chuci Zhangju. Chapter Two covers the formation process from the text Chuci to Chuci Zhangju, centering on the inherited relation between two texts. Chapter Three discusses the order of arrangement of Chuci Zhangju, suggesting that the order is related to Chuci Shiwen so as to analyze the structural system of canonical texts and its commentaries. Chapter Four centers on Wang Yi's commentaries, and further clarifies how Wang Yi has responded to predecessors' debate on QuYuan during Han Dynasty period, in order to construct and reinforce the authority for his interpretation. Chapter Five focuses on the rhymed annotation, pointing out the correlation between it and its features, forms, times, and predecessors. Chapter Six analyses the disputes over the issue Yi-yun and Huo-yue, suggesting that the existing text has been amended by people of former times, and has little relation with Wang Yi indeed. Chapter Seven is the conclusion, summarizing the key points and the major findings of the thesis. / 陳鴻圖. / Adviser: Yiu Kwan Wong. / Source: Dissertation Abstracts International, Volume: 73-03, Section: A, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (p. 150-167). / Electronic reproduction.
