Contribution au réglage de la tension sur un réseau HTA avec producteurs. Apport de la flexibilité de la demande. / Voltage control on a distribution network with distributed generations. Contribution of the demand flexibility

He, Yujun 05 March 2015 (has links)
L’intégration des producteurs décentralisés (DG) dans un réseau de distribution peut modifier le profil de tension et influencer le réglage de tension conventionnel. Pour le bon fonctionnement du réseau, le raccordement des DG ainsi que les charges grosses sont limités par le dimensionnement du réseau. Les travaux de cette thèse ont pour but de proposer une approche du réglage de tension dans un réseau de distribution avec producteur, en appuyant sur la flexibilité de la demande. Les moyens de réglage de tension seront constitués du régleur en charge (OLTC), la régulation de DG ainsi que la demande flexible. Une optimisation centralisée de type MINLP est proposée pour coordonner ces moyens de réglage. Il est montré que si les moyens de l’OLTC et de la puissance réactive ne suffissent pas de lever la contrainte de tension, il faut réduire la puissance active de producteur. Pour le gain de producteur, la demande flexible peut être considérée comme une source active. La modulation de « demand response » (DR) utilisant les charges thermiques est alors proposée au réglage de tension. L’effet de rebond est pris en compte pour les charges thermiques afin de ne pas affecter le profil de tension après l’action de DR. Ces travaux permettent d’envisager un réglage de tension plus active dans le réseau intelligent et augmenter la flexibilité du réseau. / Growth of distributed generations (DG) in actual distribution networks will bring voltage issues that cannot be fixed by conventional voltage control means. For the sake of network safety, the size of DG and load in a distribution network is limited by the network parameters. The research described in this thesis aims to propose a voltage control strategy on distribution networks using the flexibility of demand. The voltage control means will consist of the on load tap changer (OLTC), the regulation of DG, and flexible demand. A centralized optimization of MINLP type is proposed to coordinate these voltage control means. It shows if it is not able to remove the voltage constraint with OLTC and reactive power regulation, then it must reduce the active power of DG. In order not to reduce active power of DG, the flexible demand is considered as an active source to take part in voltage control. The demand response (DR) modulation using thermal loads is thus proposed for voltage control. For the thermal load, the cold load pick-up (CLPU) effect must be taken into account in order not to affect the voltage profile after DR action. This work allows us to consider a voltage control strategy more active in smart distribution network and improve the flexibility of network.

Les méduses : histoire de leur classification, de leurs moyens d'étude et de leur représentation, de l'Antiquité à la fin du XIXème siècle / Jellyfish : history of their classification, their means of study and their representations, from Antiquity to the end of the 19th century

Vial, Danièle 09 November 2018 (has links)
Perçues jusqu’au XIXe siècle comme des masses gélatineuses aux propriétés urticantes, les méduses ont été classées dans le groupe des zoophytes, organismes intermédiaires entre les animaux et les végétaux. Les savants s’en sont alors servis pour démontrer la continuité entre les êtres vivants végétaux et animaux et elles sont devenues des arguments essentiels dans l’établissement de l’échelle des êtres. A partir du XIXe siècle, on découvre, en particulier grâce à la microscopie, la complexité de leur anatomie, ce qui permet enfin de les caractériser de manière positive. Au milieu du XIXe siècle, on met en évidence les différentes phases de leur cycle de vie et l’organisation en colonie de certaines méduses. Les méduses deviennent alors l’un des principaux centres d’intérêt des zoologistes et des embryologistes qui cherchent à trouver la signification évolutive des différentes étapes de leur développement. Le terme de méduse apparaît alors pour désigner un de leurs stades de vie. En parallèle de cette histoire conceptuelle, les différentes étapes de cette classification ont été marquées par des difficultés d’étude qui ont fait que les méduses constituaient un des rares groupes non définis par des caractères positifs à la fin du XVIIIe siècle. En effet, si les expéditions scientifiques ont permis de récupérer de nombreux échantillons, bien vite s’est posé le problème de leur conservation. Face aux difficultés de maintenir leur morphologie et leurs couleurs après leur prélèvement, les images naturalistes de méduses sont donc devenues des objets d’étude essentiels dans la connaissance et la classification de ces organismes. Ces images donnent un reflet de l’évolution conceptuelle et technique, qui a accompagnée la classification des méduses / Perceived until the 19th century as gelatinous masses with stinging properties, jellyfish were classified in the group of zoophytes, intermediate organisms between animals and plants. Scientists then used it to demonstrate continuity between plant and animal living beings and became essential arguments in establishing the scale of beings. From the nineteenth century, we discover, particularly through microscopy, the complexity of their anatomy, which finally allows to characterize them positively. In the mid-nineteenth century, we highlight the different phases of their life cycle and the colony organization of some jellyfish. Jellyfish become one of the main interests of zoologists and embryologists who seek to find the evolutionary significance of the different stages of their development. The term jellyfish then appears to designate one of their life stages. In parallel with this conceptual history, the various stages of this classification were marked by study difficulties which made jellyfish one of the few groups not defined by positive characters at the end of the eighteenth century. Indeed, if the scientific expeditions allowed to recover many samples, quickly the problem of their conservation was posed. Faced with the difficulties of maintaining their morphology and their colors after their collection, the naturalistic images of jellyfish have thus become essential objects of study in the knowledge and classification of these organisms. These images give a reflection of the conceptual and technical evolution, which accompanied the classification of jellyfish

Vliv demografických změn na reálnou úrokovou míru a kapitálové toky / The impact of demographic changes on the real interest rate and international capital flows.

Dybczak, Kamil January 2003 (has links)
The demographic structure seems to change dramatically over the next 50 years in the Czech Republic. The aim of this study is to assess the impact of expected demographic changes on the future development of a real interest rate and international capital flows. In order to simulate the impact of the expected demographic changes upon the mentioned variables we apply a computable overlapping generations model. The real interest rate development is simulated under a closed economy assumption. As a result of the future expected demographic changes labour-capital ratio tends to fall, i.e. the real interest rate diminishes. The range of a change is significantly affected by a public budget closure rule. In case of an endogenous income tax rate, the real interest rate falls down by 0.5 percentage point. On the contrary, the real interest rate decreases by almost 1 percentage point in case when public transfers adjusted. Assuming an open economy, we simulate the impact of the expected demographic changes on the international capital flows between the domestic economy and the rest of the world. In case of increasing ratio of older agents, the aggregate domestic wealth surpasses the demand for capital by domestic firms. As a result a part of domestic capital is exported abroad. Increasing level of net foreign assets contributes to positive change in ratio of the balance of payment to the domestic production in a range from 2 to 5 percentage points over next 40 years if income taxes or public transfers change respectively.

Um estudo sobre o processo de transmissão cultural / An study about the cultural transmission process

Djalma Francisco Costa Lisboa de Freitas 27 June 2013 (has links)
Buscamos discutir e identificar os efeitos de três mecanismos de transmissão cultural utilizados pelos participantes em 4 arranjos experimentais: Arranjo Experimental I: a) contato com os materiais produzidos pelas gerações prévias; b) contato com a geração prévia na coparticipação e; c) contato com as gerações prévias através da observação Arranjo Experimental II: contato com os materiais produzidos pelas gerações prévias; Arranjo Experimental III: ) contato com as gerações prévias através da observação e; Arranjo Experimental IV: contato com a geração prévia na coparticipação. Os participantes tiveram de desenhar um Barco em três situações distintas. Cada situação foi identificada como: Fase A, B e C. Desenvolvemos entrevistas curtas nos intervalos de cada fase com vistas a identificar construções de significados de cada participante frente ao que os tocaram nas tarefas. Nosso estudo partiu de uma reorganização do projeto desenvolvido por Caldwell e Millen (2008) onde as autoras buscaram, desde um olhar evolucionista da cultura, identificar a perpetuação de produtos das atividades ao longo das gerações de participantes. Diferentemente de Caldwell e Millen, partimos de uma proposta teórico-metodológica advinda da disciplina nomeada como Psicologia Cultural onde se pretende estudar, discutir e se posicionar perante as complexas relações que as pessoas estabelecem consigo, com os outros e com a cultural em seu mundo, nesta perspectiva as novidades emergentes nas relações ganham maiores destaque em comparação com as regularidades e perpetuações. Com isso, consideramos neste estudo a cultura como sendo estruturas (estabilidades) e processos interativos (variações) que restringem e permitem as ações das pessoas em suas relações transformativas que são estabelecidas em seus mundo. É nesta medida, também, que compreendemos o processo de transmissão cultural como um constructo utilizado para estudarmos como as pessoas apreendem e transformam aspectos culturais de uma geração a outra. Como sínteses dos principais resultados destacamos que: 1) na interação indivíduo(s)-cultura(s) existe uma constate variação possibilitando, restringindo e permitindo a emergência de estabilidades e variações em dinâmicas bidirecionais e multidirecionais de transformação; 2) a observação da geração prévia e o contato com estas gerações através dos artefatos produzidos por elas promovem nítidas estabilidades nas produções e significações dadas pelos participantes da pesquisa em comparação com tarefas realizadas somente em coparticipação; 3) pudemos identificar a emergência de novidades, ora sutis, ora outra, bastante evidentes nas relações estabelecidas entre os participantes; 4) a relação participante-pesquisador-pesquisa ganha dimensões e implicações que merecem maior atenção no estudo de processos culturais, desde metodologias experimentais, em Psicologia Cultural. Portanto, notamos que a forma proposta neste estudo acerca de como vislumbrar a cultura e os caminhos teórico-metodológicos seguidos permitiu-nos trabalhar conceitualmente e experimentalmente sobre o processo de transmissão cultural e, portanto, sobre o estudo de processos culturais. Pudemos observar que além de nos dar indícios de que o processo de transmissão cultural garante a singularidade de cada cultura através da observação da geração prévia em ação, da coparticipação com ela e do contato com artefatos culturais (em diferentes graus e medidas), esta pesquisa nos permitiu questionar e cogitar estudos futuros sobre o fazer científicoexperimental em psicologia cultural / The interest of this research is to discuss and identify the effects of three cultural transmission mechanisms used by participants in 4 experimental arrangements: Experimental Arrangement I: a) contact with the materials produced by tradition; b) contact with the tradition of co-participation, and c) contact with the tradition through observation; Experimental Arrangement II: contact with the materials produced by tradition; Experimental Arrangement III: Contact with the tradition through observation and; Experimental Arrangement IV: Contact with the tradition through co-participation. The participants had to draw a \'boat\' in three different situations. Each situation has been identified as: Phase A, B and C. Interviews were carried out in short intervals of each phase in order to identify constructions meanings, variations and stabilities concerning the interpretation given by each participant in relation to what was noticed in the tasks. Our study was a reorganization of the project developed by Caldwell and Millen (2008) where the authors sought from a cultural evolutionary perspective, identifying the perpetuation of products of activities throughout the generations of participants. Unlike Caldwell and Millen, we from a theoretical and methodological proposal coming from the discipline called Cultural Psychology where intends to study, discuss and understand the complex relationships, in which, people establish themselves, with others and with the world in its cultural field, in this perspective the emergence of novelties in relations gain greater prominence compared to the regularities and perpetuations. Thus, in this study weve considered culture as structures (stabilities) and interactive processes (variations) that constrain and enable the actions of people in their transformative relationships that are established in their world. Also, Cultural transmission is a construct used to understand the process in which cultural aspects are apprehended by people that interact with different cultures or between different generations within a culture. Main Results: 1) the individual(s)-culture(s) relations constraining and enabling the emergence of stability and variations in a dynamic bidirectional and multidirectional process, 2) the observation of the previous generation and contact with these generations through the artifacts produced by they promote more stabilities in products and meanings given by the participants in their tasks in comparison with coparticipation, 3) were able to identify the emergence of novelties, sometimes subtle, sometimes quite evident, in relationships established among the participants, 4) the relationship participantresearcher acquire dimensions and implications that deserve more attention in the study of cultural processes, from experimental methodologies, in Cultural Psychology. Therefore, weve noticed that the form proposed in this study about how to foresee the culture and theoretical-methodological ways followed, allowed us to work conceptually and experimentally on the process of cultural transmission and, therefore, on the study of cultural processes. Weve observed that besides giving us evidence that the process of cultural transmission ensures the uniqueness of each culture through observation of the previous generation in action, the joint participation with it and contact with cultural artifacts (in different degrees and measures), this research allowed us to question and contemplate future studies on the scientific-experimental in cultural psychology

This is a qualitative study that used the clinical method. We interviewed four mothers whose children were treated by the researcher, cases in which there was detected problems or changes in mother-child bond. Data collection occurred through interviews in the form of "History of Life." The data analysis was performed by systematic reading of the interviews and understanding the dynamics of utterances, from which each cases described by categories. The discussion of the cases was based on psychoanalytic theory and concepts of psychic transmission between generations. The work also presents a historical overview about motherhood. The results showed that motherhood has experiences that tare common to mothers interviewed, however own gains settings from the life story of each one. The establishment of an affective bond between mother and child health arises as a result of numerous factors, among which the existence, for the mother of the parental affection in his childhood, a harmonious marital relationship, a pregnancy with a predominance of positive experiences and the ability to reframing of conflicts, which avoids the projection of pathological feature sin the child, preventing changes in the bond with the same. As concluding remarks, stressed the need to develop programs of psychological support during and after pregnancy, both mother and baby to the father, to strengthen family bonds. / O presente estudo teve por objetivo analisar o vínculo afetivo mãe-filho, considerando a história de vida da mãe, incluindo aspectos como as vivências de sua infância, da gravidez, do parto, do puerpério e do relacionamento conjugal. Trata-se de uma pesquisa qualitativa que utilizou o método clínico. Foram entrevistadas quatro mães cujos filhos eram atendidos pela pesquisadora, casos em que se observou haver dificuldades ou alterações no vínculo mãe-filho. A coleta de dados se deu por meio de entrevista em forma de “História de Vida.” A análise de dados foi realizada através da leitura sistemática das entrevistas e da compreensão dinâmica das verbalizações, a partir das quais se descreveu cada caso através das seguintes categorias: caracterização, história familiar, história da relação com o parceiro, vivências da gravidez, vivências do parto e puerpério, relação atual com o pai da criança e relação vincular mãe-filho. A discussão dos casos foi baseada na teoria psicanalítica e nos conceitos da transmissão psíquica entre gerações. O trabalho apresenta ainda um apanhado histórico a respeito da maternidade. Os resultados demonstraram que a maternidade possui vivências que são comuns às mães entrevistadas, contudo ganha configurações próprias a partir da história de vida de cada uma. O estabelecimento de um vínculo afetivo mãe-filho saudável surge como resultado de vários fatores, dentre os quais a existência, para a mãe, de figuras parentais afetivas em sua infância, um relacionamento conjugal harmonioso, uma gravidez com predomínio de vivências positivas e a capacidade de ressignificação dos próprios conflitos, que evita a projeção de aspectos patológicos no filho, prevenindo alterações no vínculo com o mesmo. Como considerações finais, salientou-se a necessidade de se desenvolver programas de apoio psicológico, durante e após a gravidez, tanto à mãe quanto ao pai e ao bebê, a fim de fortalecer os vínculos familiares.

Aims to demonstrate the emergence of a new generation of architects, which can be seen from the criterion of the generations, recognizing it linked to the dynamics of global generations. Moreover, the thesis comprises these architectures such as an emerging complex system, as a set of numerous connections and interactions which act on each other in network, producing qualities or properties characteristic of emergence. These architectural systems work interconnected, forming a collective whole. Some common themes, but not homogeneous, were prioritized in order to baste and sew some consistency to the historic building. Guidelines related to interpretations of context and tectonic dimension were developed as a coherent alternative to this structure, besides emphasis on public and social dimension of architecture, especially when articulated to the difficult circumstances of the Latin American cities. Such analysis has been attentive to the historical process of emergence and affirmation of this new generation, understanding it not as a simple way of continuity or natural evolution of the architectures produced in Latin America since the last century, much less as an attitude of break with the generations past, but rather as a dialectical interpretation between certain modernities that can be resumed and the development of new attitudes inherent to the connection possibilities that these architects make with the global generations. The results achieved signaled efforts of transcendence and overcoming of this supposed dichotomy in an attempt to break through the barriers and shorten distances. / Esta tese aborda as arquiteturas recentes produzidas na América Latina entre 1991 e 2011. Tem por objetivo comprovar o surgimento de uma nova geração de arquitetos que pode ser observada a partir do critério das gerações, reconhecendo-a vinculada à dinâmica das gerações globais. Além disso, a tese compreende estas arquiteturas como um sistema complexo emergente, como um conjunto de numerosas conexões e interações que agem mutuamente em rede, produzindo qualidades ou propriedades características da emergência. Constituem sistemas arquitetônicos que trabalham interconectados, formando um todo coletivo. Alguns temas comuns, porém não homogêneos, foram priorizados no sentido de alinhavar e costurar certa coerência à construção histórica. Pautas vinculadas às interpretações de contexto e dimensão tectônica foram desenvolvidas como uma alternativa bastante coerente para esta estruturação, além da ênfase dada à dimensão pública e social da arquitetura, principalmente quando articulada às difíceis circunstâncias das cidades latino-americanas. Tal análise esteve atenta ao processo histórico de surgimento e afirmação desta nova geração, entendendo-o não como um simples percurso de continuidade ou evolução natural das arquiteturas produzidas na América Latina desde o século passado, e muito menos como uma atitude de ruptura com as gerações anteriores, mas sim, como uma interpretação dialética entre certas modernidades que podem ser retomadas e o desenvolvimento de novas atitudes propositivas inerentes às possibilidades de conexão que estes arquitetos estabelecem no movimento das gerações globais. Os resultados alcançados sinalizaram esforços de transcendência e superação dessa suposta dicotomia, na tentativa de romper as barreiras e encurtar distâncias.

A transmissão psíquica e a constituição do vínculo conjugal / Psychic transmission and constitution of marital bond

Maria Lucia de Souza Campos Paiva 27 March 2009 (has links)
Na contemporaneidade, mulheres e homens estabelecem diversos tipos de vínculos amorosos. Já não podemos dizer que existe um modelo único de casamento e família, tampouco fazer previsões a respeito da durabilidade de uma relação matrimonial. Durante muitos anos os estudos acadêmicos focaram a questão do rompimento do vínculo conjugal. Este trabalho foi justamente realizado a respeito dos casais que permanecem casados por muitos anos. Assim, o objetivo geral desta tese foi estudar a transmissão psíquica entre as gerações e a interferência da mesma na constituição e manutenção do vínculo conjugal. Pretendemos entender as influências que os casais receberam das famílias de origem e como elas interferiram na possibilidade de o casal desenvolver uma identidade conjugal própria, enfocando tanto as influências conscientes como as inconscientes. Abordamos, então, o mecanismo de transmissão psíquica intergeracional e transgeracional na formação e manutenção do vínculo conjugal. Utilizamos a psicanálise como referencial teórico, mais precisamente as formulações teóricas de René Kaës. O método utilizado foi o clínico-qualitativo, proposto por Turato (2003). A pesquisa foi realizada com dois casais casados entre vinte e trinta anos e que não estavam em processo terapêutico. A coleta de dados foi feita por meio de entrevista semiaberta, com os dois em conjunto, e pela aplicação das pranchas 2, 4, 7RH, 7MF, 19 e 16 do Teste de Apercepção Temática, com cada cônjuge, separadamente. Com base no material coletado, evidenciamos a presença do declínio do masculino nas várias gerações das famílias de origem desses casais e apontamos para a transmissão psíquica transgeracional da fragilidade masculina. As principais conclusões indicam que as heranças psíquicas transgeracionais foram determinantes na constituição do vínculo conjugal para esses casais pesquisados e dificultaram o estabelecimento de uma identidade conjugal e familiar própria. / This study deals with couples that remain married for many years. The general objective of this dissertation is to study the psychical transmission between generations and its interference in the constitution and maintenance of the marital bond. The purpose is to understand the influence couples receive from their originating families and how it interfered with the possibility of the couple to develop their own marital identity, focusing on both conscious and unconscious influences, dealing with the intergenerational and the transgenerational mechanisms of psychical transmission in the construction and maintenance of the marital bond. The theoretical reference is based on Freud; specifically, the theoretical formulations of René Kaës. The method used was the clinical-qualitative, proposed by Turato (2003). The research was performed with two couples, married for 20 to 30 years and were not participating in therapeutic treatment. Data was obtained through a semi-open interview with the couple, and the application of cards 2, 4, 7RH, 7MF, 19, and 16 of the Thematic Apperception Test. Based on the collected material, it became evident the decline of the male persona in the various generations of the couples originating families and the psychical transgenerational transmission of male fragility. The main conclusions indicate the mental transgenerational legacy was a determinant in the marriage constitution of the studied couples, making the establishment of their own marital and family identity difficult.

Comment parents et grands-parents influencent l’apprentissage du "bien manger" chez l’enfant : contribution de la transmission intergénérationnelle dans le contexte de la consommation alimentaire / How parents and grandparents influence food consumption learning by children : the role of the intergenerational transmission in the context of food consumption

Josion-Portail, Margaret 03 December 2014 (has links)
La question de la transmission intergénérationnelle du « bien manger » se trouve aujourd’hui au cœur des préoccupations des pouvoirs publics, qui souhaitent promouvoir auprès des jeunes générations une conception de la « bonne » alimentation dépassant le cadre de l’équilibre alimentaire ; or, paradoxalement, la littérature sur le rôle des acteurs familiaux dans le développement des connaissances de l’enfant liées à cette conception élargie de la « bonne » alimentation est assez succincte. A l’appui d’études documentaire, qualitative et quantitative menées auprès de parents et de grands-parents, cette recherche analyse le rôle des grands-parents, et parents, dans l’apprentissage du « bien manger » chez l’enfant. Les contributions de ce travail se situent à plusieurs niveaux (1) définition et conceptualisation du construit du « bien manger » (2) identification du rôle spécifique des grands-parents dans la transmission du « bien manger » à l’enfant (3) comparaison entre les parents et les grands-parents des représentations sociales du « repas où les enfants ont bien mangé » et des pratiques de transmission (4) analyse des variables explicatives des pratiques de transmission intergénérationnelle du « bien manger » (représentations du « bien manger », générativité, centralité du rôle parental et grand-parental, reconnexion au passé personnel). / Recently, the question of how to develop the intergenerational transmission of “eating well“ practices, conceived more broadly than “eating healthy”, has received greater attention from public policy makers. However, quite surprisingly, the academic literature in this area is rather scarce. Adopting different methodological approaches – document content analysis, qualitative analysis and quantitative analysis - , this research sheds light on how the intergenerational transmission contributes to children’s learning of “eating well” within families, and on the particular role of grandparents, in comparison with parents, in this process. Theoretical contributions are provided at different levels (1) we define and conceptualize the “eating well” construct (2) we identify the specific role of grandparents in the intergenerational transfer of “eating well” (3) we compare the structure of social representations of “a meal where children have eaten well”, as well as transmission practices, between grandparents and parents; (4) we measure the influence of relevant variables (representations, generativity, parental and grandparental role centrality and reinvolvement with personal past) on intergenerational transmission of practices related to “eating well”.

Relectures des générations intellectuelles aux Etats-Unis : la vie et l’œuvre de Howard Zinn ( 1922- ) / Remapping intellectual generations in the United States : The Life and Work of Howard Zinn ( 1922- )

Ivol, Ambre 30 November 2009 (has links)
La vie et l’oeuvre de Howard Zinn cristallisent un ensemble de dynamiques contradictoires. Issu d’une génération marquée par la Grande Dépression et la Seconde Guerre mondiale, il deviendra – à la différence d’autres figures publiques de sa génération – une figure phare de la nouvelle gauche et de son pendant historiographique, la nouvelle histoire sociale. Hissé ainsi au rang d’intellectuel engagé suite aux mouvements sociaux des années 1960, il reste pourtant influencé par la Weltanschauung de son temps. Or loin d’être une trajectoire atypique au sein de sa classe d’âge, un tel parcours permet d’éclairer autrement les comportements collectifs de cette génération, notamment en permettant de s’extraire d’une grille de lecture encore largement axée sur des identités culturelles spécifiques. A ce titre, il permet une relecture des générations intellectuelles aux Etats-Unis associant des communautés trop souvent dissociées selon une approche idéologique plus inclusive. / Howard Zinn’s life and work embodies contradictory dynamics. Though himself from a generation which came of age during the Great Depression and World War Two, he became a leading figure of the New Left as well as a representative of the new social history. He indeed rose to prominence as a public intellectual through his involvement in the social movements of the 1960s, while remaining influenced by the Weltanschauung of his own times. Far from being atypical for his age group, his trajectory sheds new light on the collective behavior of this generation. Indeed, it points to the possibility of going beyond a historiography which has been largely informed by specific cultural identities. By moving away from an approach too narrowly ideological, the study of Howard Zinn’s life and work will offer a more inclusive approach to generational issues in the United States.
