Lidén, Konrad January 2021 (has links)
Howdoyoudo (HDYD): How do you do, Howdy! Howdy (HD): Howdy, Howdoyoudo! HDYD: Vi ser ut att få en fin dag idag, tycker du inte? Synd att den måste befläckas med det vanliga smutsgörat. En efterlysning har kommit in. HD: Det har hänt igen? HDYD: Ja, det är samma visa varje gång. En luststyrd elev som oaktsamt klivit in på högskoleterritorium och inte tänkt på konsekvenserna... men räkenskapens tid kommer till alla: textförklaringen måste fram.

En ny mansbild? : En kvalitativ studie av de manliga huvudkaraktärerna i serierna Skam och Normala människor / A new male image? : A qualitative study of the male main characters in the series Skam and Normal People

Karlsson, Wilma, Ekmark, Vendela January 2021 (has links)
I denna uppsats analyseras de manliga huvudkaraktärerna i dramaserierna Skam (2016) och Normala människor (2020) med syfte att undersöka om det finns tendenser för en ny mansbild i media. För att undersöka detta användes teoretiska perspektiv som representation, stereotyper, genus, heteronormativitet och hegemonisk maskulinitet. Ett analysschema skapades utifrån hegemonisk maskulinitet och forskning kring en ny mansbild i media. För att analysera materialet användes kvalitativ innehållsanalys i form av semiotik som metod. Resultatet visade att den manliga huvudkaraktären från Skam upprätthöll fler karaktärsdrag från den hegemoniska maskuliniteten jämfört med den manliga huvudkaraktären från Normala människor. Karaktären från Normala människor uppvisade fler tendenser från en ny mansbild. / In this essay, we analyze the male main characters in the drama series Skam (2016) and Normal People (2020) with the aim of examining whether there are tendencies for a new male image in the media. To investigate this, theoretical perspectives such as representation, stereotypes, gender, heteronormativity and hegemonic masculinity were used. An analysis scheme was created based on hegemonic masculinity and research on a new male image in the media. To analyze the material, qualitative content analysis in the form of semiotics was used as a method. The results showed that the male main character from Skam maintained more character traits from the hegemonic masculinity compared to the male main character from Normal people. The character from Normal people showed more tendencies from a new male image.

[pt] A INTERRELAÇÃO ENTRE EXPERIÊNCIAS, CRENÇAS E AÇÕES NA AULA DE LÍNGUA ESTRANGEIRA: VIVÊNCIAS DE UMA PROFESSORA DE FRANCÊS E DE UM PROFESSOR DE INGLÊS / [en] THE INTERRELATION BETWEEN EXPERIENCES, BELIEFS AND ACTIONS IN THE FOREIGN LANGUAGE CLASS: EXPERIENCES OF A FRENCH TEACHER AND AN ENGLISH TEACHER

BRUNA GONCALVES PAVAM 12 July 2021 (has links)
[pt] Inserido no campo da Linguística Aplicada Contemporânea (Moita Lopes, 2006, 2013), atravessado pelos princípios da Prática Exploratória (Allwright, 2006; Miller, 2006, 2013) e orientado pelos estudos de Crenças no ensino-aprendizagem de línguas estrangeiras (Barcelos e Abrahão, 2006; Silva, 2010), o presente estudo analisa a interrelação entre experiências, crenças e ações a partir da interpretação das vivências de dois professores de uma instituição pública de ensino. Dentro de uma perspectiva qualitativa e interpretativa (Denzin & Lincoln, 2006), trata-se de uma pesquisa reflexiva de cunho autoetnográfico, da qual eu, professora de francês, e meu colega da disciplina de inglês somos praticantes-participantes. Alinhada às áreas de estudo supracitadas e ao paradigma qualitativo-interpretativo, que compreendem a produção de conhecimento como estando entrelaçada com as práticas vivenciadas em contextos socio-historicamente situados, não ambiciono propor soluções generalistas baseadas em verdades homogeneizantes. A motivação para esta pesquisa surge em 2018, no contexto de um projeto de turmas de readequação idade-série, na instituição na qual meu colega e eu atuamos. Trata-se de um projeto de correção de fluxo escolar em cujo contexto desenvolvemos um trabalho interdisciplinar por nós nomeado Docência em Parceria. Os dados foram gerados a partir da gravação em áudio de uma conversa reflexiva, cujos excertos selecionados para análise estão apresentados em função dos temas emergentes da interação. Meu enfoque se volta aos entendimentos relativos às crenças sobre o ensino-aprendizagem (de línguas estrangeiras) que meu colega e eu coconstruímos reflexivamente na ocasião dessa conversa. / [en] Inserted in the field of Contemporary Applied Linguistics (Moita Lopes, 2006, 2013), interwoven by the principles of Exploratory Practice (Allwright, 2006; Miller, 2006, 2013) and guided by the studies of Beliefs in the teaching-learning of foreign languages (Barcelos and Abrahão, 2006; Silva, 2010), the present study analyzes the interrelationship between experiences, beliefs and actions based on the interpretation of the experiences of two teachers from a public educational institution. Within a qualitative and interpretive perspective (Denzin & Lincoln, 2006), this is a reflective research of an autoetnographic nature, of which I, a French teacher, and my colleague, an English teacher, are participating practitioners. In line with the aforementioned areas of study and the qualitative-interpretative paradigm, which understands the production of knowledge as being intertwined with the practices experienced in socio-historically situated contexts, I do not aim to propose general solutions based on homogenizing truths. The motivation for this research arises in 2018, in the context of a project of age-grade readjustment classes, at the institution in which my colleague and I work. This is a flow correction project in the school context in which we developed an interdisciplinary work that we named Teaching in partnership. The data were generated through a reflective conversation, whose excerpts selected for analysis are presented according to the themes emerging from the interaction. My focus is on the understandings related to the beliefs about foreign language teaching-learning that my colleague and I co-constructed reflexively at the time of this conversation.

[pt] DESENVOLVIMENTO E CONTROLE DE UM ACOPLADOR ELÁSTICO BASEADO EM ELASTÔMEROS PARA SEA / [en] DESIGN AND CONTROL OF AN ELASTOMER-BASED ELASTIC COUPLING FOR SEA

FELIPE REBELO LOPES 02 October 2023 (has links)
[pt] Questões de segurança têm sido fatores cruciais para que robôs se tornem aptos a trabalhar em colaboração com seres humanos. Esse esforço envolve um controle de força mais refinado e uma certa flexibilidade nas juntas para que a adaptação dos robôs ao ambiente real e às atividades comuns dos seres humanos seja efetiva. Uma das tecnologias com esse objetivo é o Atuador Elástico em Série (SEA - Series Elastic Actuator), que apresenta um bom desempenho para controle de força, tolerância a impactos causados por agentes externos, baixa impedância, e a redução de vibrações mecânicas. Em um SEA, um elemento elástico passivo é adicionado entre o motor e o elo acionado, a fim de gerar flexibilidade. Este elemento pode ser uma mola, ou outro elemento deformável com flexibilidade caracterizada por sua geometria e pela elasticidade do material utilizado. Esta tese propõe um Atuador Elástico em Série Baseado em Elastômero (eSEA), cuja flexibilidade é obtida a partir de um elastômero depositado entre dois elementos metálicos: um interno acoplado ao atuador, e o outro externo acoplado ao elo. O eSEA foi projetado e avaliado por software de CAD e Elementos Finitos, com o intuito de obter a flexibilidade desejada para a aplicação. Foram produzidas duas versões do eSEA, com duas durezas diferentes: 10 e 55 Shore A. Testes estáticos com células de carga foram executados para caracterizar a rigidez dos eSEA. Os eSEA foram instalados em manipuladores robóticos especialmente desenvolvidos para essa tese. Experimentos compararam o desempenho das técnicas de controle com e sem a influência dos eSEA, mostrando que o uso dos eSEA diminuiu os erros de posicionamento do manipulador e possibilitou o controle de força sem a necessidade de sensores específicos. A fim de criar um modelo para que a estimativa do torque seja mais precisa a partir do eSEA, foram realizadas técnicas de identificação para estimar uma função de transferência que melhor representa o alongamento da borracha. E combinados com modelos NARX e NARMAX do erro de estimativa, gerou-se um modelo híbrido para o elemento elástico no qual soma-se a função de transferência com o erro modelado. / [en] Safety issues have been crucial factors for robots to become able to work in collaboration with humans. This effort involves more refined force control and a certain flexibility at the joints, for the robots to better adapt to real environments and common human tasks. A technology with this objective is the Series Elastic Actuator (SEA), which presents good performance for force control, tolerance to impacts caused by external agents, low impedance, and dampening of mechanical vibrations. In an SEA, a passive elastic element is added between the motor and the driven link, in order to generate a desired flexibility. This element can be a spring, or else another deformable element with flexibility characterized by its geometry and material elasticity. This thesis proposes an Elastomer-Based Series Elastic Actuator (eSEA), whose flexibility is obtained from an elastomer deposited between two metallic elements: an internal element attached to the actuator, and an external element attached to the link. The eSEA was designed and evaluated by CAD and Finite Element software, in order to obtain the desired flexibility for the application. Two versions of the eSEA were produced, with two different hardnesses: 10 and 55 Shore A. Static tests with load cells were then executed to characterize the stiffness of the eSEA. The eSEA elements were installed on robotic manipulators especially developed for this thesis. Experiments compared the performance of control techniques with and without the influence of eSEA, showing that the use of the eSEA reduced manipulator positioning errors and enabled force control without the need for specific sensors. In order to create a model for more accurate torque estimation from eSEA, identification techniques were performed to estimate a transfer function that best represents the rubber elongation. And combined with NARX and NARMAX models of the estimation error, a hybrid model was generated for the elastic element in which the transfer function is added together with the modeled error.

[pt] DESAGREGAÇÃO DO CONSUMO DE ENERGIA ELÉTRICA PARA CONSUMIDORES RESIDENCIAIS USANDO SÉRIES DE FOURIER E UM MODELO DE OTIMIZAÇÃO INTEIRA MISTA / [en] ENERGY DISAGGREGATION FOR RESIDENTIAL CONSUMERS USING FOURIER SERIES AND A MIXED INTEGER OPTIMIZATION MODEL

MARILIA ZACARIAS COSTA DE OLIVEIRA 15 September 2020 (has links)
[pt] Este trabalho apresenta um método de Monitoramento Não Intrusivo de Carga de Aparelhos elétricos (do inglês Non-Intrusive Appliance Load Monitoring – NIALM) supervisionado, usando técnicas de análise de estados estacionários, para desagregação do consumo elétrico residencial a partir de uma única medição, sem a necessidade de instalação de medidores individuais nos dispositivos. A metodologia proposta divide o problema em duas etapas. Inicialmente, há um pré-processamento para identificação e desagregação dos aparelhos que apresentam comportamento periódico, modelados a partir da estimação dos parâmetros da série de Fourier. Na etapa seguinte, os resultados obtidos são combinados a um modelo de otimização linear-inteiro misto para desagregação dos equipamentos não-periódicos, buscando minimizar a diferença entre a curva de carga total lida e a soma das curvas de carga desagregadas por dispositivo. Uma aplicação didática é realizada para validação do método proposto com dados reais e, por fim, é apresentada uma análise de viabilidade econômica da migração para a tarifa branca aplicada no Brasil. Os resultados mostram que, ao utilizar dessa metodologia, é possível que o usuário avalie se há ou não vantagem em deslocar parte do seu consumo de energia para fora do horário de ponta para obter benefício na sua fatura de energia elétrica. / [en] This work presents a supervised Non-Intrusive Appliance Load Monitoring (NILM) method, or energy disaggregation, for residential consumption, which aims to decompose the aggregate energy consumption data collected from a single measurement point into device-level consumption estimation using steady state analysis techniques with no need to install individual meters on appliances. The proposed methodology considers two steps to face the problem. Firstly, periodical appliances are modeled from the estimation of Fourier series parameters and extracted from the total power measured. Secondly, the results obtained are combined with a Mixed Integer Linear Programming proposed to disaggregate the remaining appliances, which minimize the difference between the total aggregated load and the sum of the estimated load curves per appliance. A study case is performed with a real case to validate the proposed method and indicates that the model can be useful for practical applications, such as helping evaluate the possibility of the consumers changing the modality of their tariff contract from the conventional tariff to the new Brazilian modality called white tariff.

Kan kvinnor prata om något annat än män? : En jämförande narrativ analys av Tv-serierna Skilda världar och SKAM / Can women talk about anything other than men? : A comparative narrative analysis of the TV series Skilda världar and SKAM

Jevrell, Eleonora January 2017 (has links)
“Can women talk about anything but men? – a comparative narrative analysis of the television series “Skilda världar” and “SKAM””   The purpose of this study is to compare how young women are portrayed in two different Scandinavian television shows. Especially which roles they are given as young women in different decades since the television shows were aired with a 19-year time difference. The first one being the Swedish “Skilda världar” and the second one is the Norwegian international internet success “SKAM”. Theories used in this study are postmodern theories and gender theories. Anja Hirdmans Tilltalande Bilder (2001) are used to explains how women are presented in the media. It follows by a subchapter on how women are portrayed in TV series and soap operas. The theories and previous research served as tools for the analysis. A narrative method has been used, with Vladimir Propps functions to make indentations. The three first episodes of each series has been analysed with 1-4 indentations. In addition to Propps functions the actant-modell of Algirdas J. Greimas has been used to explain the roles of the characters. The result of the study shows a difference between the main young female characters. Sandra, the main female character of “Skilda världar” is much more controlled by her family. She’s to a greater extent treated like an object than the female main character in “SKAM”, Eva. Eva shows more moral courage and independency. Both of the leading female roles have a dream of liberating themselves. They have various types of liberations but with similar elements. Sandra wants to free herself from the oppressing demands of her home, and find passion and love through a relationship. Eva wants to become more independent from her boyfriend and create an own social circle. Heterosexual relationships are the subconscious centre in both of their stories.

Développement d'une méthode de caractérisation 3D des fissures de fatigue à l'aide de la corrélation d'images numériques obtenues par tomographie X / Development of a method for 3D characterisation of fatigue crack using digital volume correlation on X-ray microtomography images

Lachambre, Joël 27 May 2014 (has links)
Ce mémoire présente une méthode mise au point pour caractériser et analyser des fissures de fatigue présentant un fort caractère tridimensionnel dans des matériaux métalliques opaques. L'analyse consiste à déterminer avec précision la position du front de la fissure étudiée et à mesurer des valeurs de facteurs d'intensité des contraintes le long du front par projection sur les séries de Williams du champ de déplacement issu de la corrélation numérique d'images 3D obtenues par tomographie aux rayons X. La corrélation d'images 3D numériques est utilisée afin de mesurer le champ de déplacement en volume lors de la mise sous chargement d'une éprouvette fissurée fatiguée. La corrélation d'images nécessitant un mouchetis, le matériau retenu pour les expériences est la fonte à graphite sphéroïdal car il présente un mouchetis 3D naturel (les nodules de graphites) parfaitement imagé par tomographie aux rayons X. Le cyclage est appliqué à l'aide d'une machine de fatigue in situ permettant d'alterner des phases de propagation de la fissure avec des acquisitions tomographiques sous différentes charges. L'introduction d'un défaut artificiel (une entaille obtenue par usinage laser) permet de maîtriser l'amorçage et la propagation de la fissure in situ. La méthode de corrélation d'images 3D numériques employée dans ces travaux étant basée sur des éléments finis, nous avons cherché à tirer profit de différents outils développés dans le cadre de cette méthode. Les surfaces libres sont spécifiées afin de bien conditionner le maillage et un enrichissement dans l'esprit des X-FEM permet de renseigner la fissure dont la position est repérée grâce à la trace laissée dans le résidu de corrélation entre l'image avant cyclage et la dernière image acquise. Une régularisation mécanique est également introduite dans le calcul sous forme d'un filtre de longueur d'onde choisie. Le champ de déplacement mesuré avec précision est ensuite projeté sur les séries de Williams augmentées des termes correctifs de Leblond et Torlai qui prennent en compte la courbure du front de la fissure. L'annulation du terme super-singulier d'ordre -1 des séries de Williams est utilisée pour détecter la position du front de la fissure. Une procédure itérative a été mise en place afin de concilier l'enrichissement et la courbure du front avec la projection sur les séries de Williams. Une fois la position du front 3D de la fissure déterminée et les valeurs des facteurs d'intensité des contraintes associées calculées, les résultats obtenus sont confrontés à la littérature. / This manuscript describes a methodology used to compute Stress Intensity Factor values along the curved front of a fatigue crack inside a nodular cast iron. An artificial defect is introduced at the surface of a small sample. The initiation and growth of a fatigue crack from this defect during constant amplitude cycling is monitored in situ by laboratory x-ray tomography. The method for processing the 3D images in order to compute SIF values is described in detail. The results obtained show variations of the stress intensity factor values along the crack front.

Evasió i exili interior en l'obra de Joan Miró: 1939-1945

Reus Morro, Jaume 07 July 2004 (has links)
L’interès d’aquesta investigació s’ha centrat en dos aspectes complementaris de l’obra de Joan Miró, del període de 1939 a 1945. Un és la producció artística i l’altre és el procés auto reflexiu. El període de la trajectòria vital i professional objecte d’anàlisi, el de major tensió emocional per a l’artista i la seva família, està marcat per inflexions significatives, però també per continuïtats. Miró fou capaç de superar l’opressió d’un ambient hostil gràcies a una severa auto disciplina en el treball, una recapitulació sobre el propi llenguatge artístic i un inèdit procés d’auto reflexió escrit. Pel que fa a la producció, hem destacat amb una especial significació dues sèries: Constellations (1940-41) i la Sèrie Barcelona (1941-1944). L’obra realitzada en aquest període és un dels exemples més interessants de com les característiques evasives, de l’absurd o tocades pel seu particular humour grotesc, suposen un contrapès al carregat ambient que l’envolta / El interés de nuestra investigación se ha centrado en dos aspectos complementarios de la obra de Joan Miró, comprendida entre el período 1939 y 1945.

Por lo que se refiere a la producción, hemos destacado con una especial significación dos series: Constellations (1940-41) y la Sèrie Barcelona (1941-1944). La obra realizada en este período es uno de los ejemplos más interesantes de como las características evasivas, del absurdo o tocadas por su particular humour grotesco, suponen un contrapeso al cargado ambiente que le rodea / The interest of our research is located in two complain aspects of Joan Miró’s work, between 1939 and 1945. One aspect is the artistic production and the other one is the self reflexive process. This vital and professional period is the most emotional tension for the artist and his family, and it is distinguished by important changes but also by continuities. Miró was into the most strict anonymous. He was able to overcome the oppression of a hostile atmosphere because he impose himself a hard auto discipline of work, a recapitulation about his artistic language, and an unpublished process of written reflection. In concerning the artistic production, we have studied two series because its special signification: Constellations (1940-41) and the Sèrie Barcelona (1941-44). The works made in this period of time are one of the most interesting examples of evasive trends, absurd or with a particular and grotesque humour. This attributes were the counter balance to the loaded climate
