Étienne Decroux (1898-1991) : "portrait du mime en sculpteur" : figures du corps au croisement des arts du spectacle et des arts plastiques / Étienne Decroux (1898-1991) : "the portrait of a mime as a sculptor" : the portrayal of a body at the intersection of scenic and fine art / Étienne Decroux (1898-1991) : "portrét mima jako sochaře" : zobrazení těla na průsečíku scénického a výtvarného uměníKolářová, Petra 26 September 2015 (has links)
Notre thèse porte sur Étienne Decroux, le créateur du mime corporel. Nous montrons que Decroux s’inspire à la fois du théâtre et de la sculpture pour concevoir son art du mime, qu’il définit comme la statuaire mobile. D’une part, il reprend le concept du masque de Jacques Copeau et celui de la sur-marionnette d’Edward Gordon Craig pour les transposer directement au corps. D’autre part, ses œuvres incarnent les formules de pathos observées dans les statues. La sculpture d’Auguste Rodin est une source d’inspiration centrale dans sa manière de représenter le corps sur scène. De plus, Decroux conçoit le corps comme une suite de prises de vues défilant devant le spectateur. Collaborant avec Étienne-Bertrand Weill qui photographie ses spectacles, il constitue une iconographie du mime pour mieux donner à voir le mouvement du corps en image. Enfin, Decroux considère le corps comme de la matière à sculpter. En s’identifiant aux sculpteurs mythiques, il met en avant l’aspect créateur de son art. Comme Pygmalion, il anime les corps de ses élèves. Comme Prométhée il transforme la société par son art aux aspects politiques. La statuaire mobile représente un concept-clé du mime corporel d’Étienne Decroux qui s’étend de la conception du mouvement sur scène à la prise de position éthique de l’homme dans le monde. / The thesis main subject is Etienne Decroux, the father of corporeal mime. The main objective is to show that Decroux draws on both theatre and sculpture, thus conceiving his art of mime as the mobile statuary. On the one hand, he takes up the concept of mask put forward by Jacques Copeau and Edward Gordon Craig's ubermarionnette, transposing both concepts directly to the body. On the other hand, he embodies the pathos formulas observed in the statues. Decroux was heavily inspired by Auguste Rodin's sculptures in order to represent the body on stage. Moreover, Decroux conceives the body as a series of images which unfold before the audience. Working along with Etienne-Bertrand Weill who photographs his shows, he creates a relevant source of iconography of the mime that unveils the movement of the body in images. Finally, for Decroux, the body is a sculpting material. By identifying himself with the mythical sculptors, he brings forward the creative aspect of his art. Just as Pygmalion, he enlivens the body of his students and, as Prometheus, he transforms the society through his political art. The mobile statuary is then a key concept in the corporeal mime that goes from the conception of the movement on stage to the ideal and the universal in man. / Disertační práce se zabývá osobností Étienna Decroux, tvůrce projektu tělesného mima (mime corporel). Jejím cílem je dokázat, že se Decroux inspiroval divadlem i výtvarným uměním k vytvoření koncepce tzv. „pohyblivé sochy“ (statuaire mobile). Z divadla přebral koncept masky Jacquesa Copeau a koncept nadloutky Edwarda Gordona Craiga, aby je převedl přímo na tělo. Ze sochařství přejímal formule patosu, zejména se inspiroval dílem Augusta Rodina a jeho koncepcí tělesné figury. Decroux pojímal tělo jako sérii obrazů, které se odvíjejí před divákem. Ve spolupráci s fotografem Étiennem-Bertrandem Weillem, který dokumentoval jeho představení, vytvářel ikonografický soubor, jenž zobrazuje mimovo tělo v pohybu. Na druhou stranu chápal tělo jako materiál, který mim modeluje jako sochař. Decroux se ztotožňoval s mytickými sochaři, aby dal najevo svoji roli umělce a tvůrce. Jako Pygmalion „oživoval“ těla svých žáků a jako Prométheus přetvářel společnost svým uměním, které mělo politický náboj. „Pohyblivá socha“ (statuaire mobile) představuje klíčový koncept umění tělesného mima Étienna Decroux, který zahrnuje jak koncepci scénického pohybu, tak etické postavení člověka ve světě.

Diminution of the lithographic process variability for advanced technology nodes / Diminution de la variabilité du procédé lithographique pour les noeuds technologiques avancésSzucs, Anna 10 December 2015 (has links)
A l’heure actuelle, la lithographie optique 193 nm arrive à ces limites de capacité en termes de résolution des motifs dans la fenêtre du procédé souhaitée pour les nœuds avancés. Des lithographies de nouvelle génération (NGL) sont à l’étude, comme la lithographie EUV (EUV). La complexité de mise en production de ces nouvelles lithographie entraine que la lithographie 193 nm continue à être exploitée pour les nœuds 28 nm et au-delà. Afin de suivre la miniaturisation le rôle des techniques alternatives comme le RET (en anglais Resolution Enhancement Technique) tels que l’OPC (Optical Proximity Correction) est devenu primordial et essentiel. Néanmoins, la complexité croissante de design et de la variabilité du procédé lithographique font qu’il est nécessaire de faire des compromis. Dans ce contexte de complexité croissante du procédé de fabrication, l’objectif de la thèse est de mettre en place une méthode de boucles de correction des facteurs de variabilité. Cela signifie une diminution de la variabilité des motifs complexes pour assurer une résolution suffisante dans la fenêtre de procédé. Ces motifs complexes sont très importants, car c’est eux qui peuvent diminuer la profondeur du champ commune (uDoF). Afin d'accomplir cette tâche, nous avons proposé et validé un enchainement qui pourra être plus tard implémenté en production. L’enchainement en question consiste en une méthodologie de détection basée sur la simulation des motifs les plus critiques étant impactés par les effets issus de la topographie du masque et du profil de la résine. En outre cette méthodologie consiste en une diminution et la compensation de ces effets, une fois que ces motifs les plus critiques sont détectés. Le résultat de l’enchaînement complété sont encourageants : une méthode qui détecte et diminue les variabilités du processus lithographique pour des nœuds de technologie de 28nm a été validée. En plus elle pourrait être adaptée pour les nœuds au-delà de 28 nm. / The currently used 193 nm optical lithography reaches its limits from resolution point of view. Itis despite of the fact that various techniques have been developed to push this limit as much aspossible. Indeed new generation lithography exists such as the EUV, but are not yet reliable to beapplied in mass production. Thus in orders to maintain a robust lithographic process for theseshrunk nodes, 28 nm and beyond, the optical lithography needs to be further explored. It ispossible through alternatives techniques: e.g. the RETs (Resolution Enhancement Techniques),such as OPC (Optical Proximity Correction) and the double patterning. In addition to theresolution limits, advanced technology nodes are dealing with increasing complexity of design andsteadily increasing process variability requiring more and more compromises.In the light of this increasing complexity, this dissertation work is addressed to mitigate thelithographic process variability by the implementation of a correction (mitigation) flow exploredmainly through the capability of computational lithography. Within this frame, our main objectiveis to participate to the challenge of assuring a good imaging quality for the process windowlimiting patterns with an acceptable gain in uDoF (usable Depth of Focus).In order to accomplish this task, we proposed and validated a flow that might be laterimplemented in the production. The proposed flow consists on simulation based detectionmethodology of the most critical patterns that are impacted by effects coming from the masktopography and the resist profile. Furthermore it consists of the mitigation and the compensationof these effects, once the critical patterns are detected. The obtained results on the completedflow are encouraging: a validated method that detects the critical patterns and then mitigates thelithographic process variability been developed successfully.

Development of Fiber Bragg Grating Sensor Based Devices for Force, Flow and Temperature Measurement for Emerging Applications in Biomedical DomainShikha, * January 2016 (has links) (PDF)
Efficient and accurate sensing of various parameters is needed for numerous applications. In this regard, different categories of sensors play a significant role and different applications require diverse sensing mechanisms owing to the operating conditions and field constraints. Among the several sensor methodologies available, optical fiber sensors have found significant attention, because of their advantages such as negligible foot print, small mass, immunity to Electromagnetic Interference, etc.
In the category of optical fiber sensors, Fiber Bragg Grating (FBG) sensors have found importance in many fields such as health monitoring of civil structures, environmental monitoring involving gas & humidity sensing, monitoring parameters like pressure, tilt, displacement, etc. In the recent times, FBGs have found applications in biomedical, biomechanical and biosensing fields.
A FBG is a periodic change of the refractive index of the core of a single mode optical fiber along its longitudinal axis. The periodic modulation in the index of refraction is obtained by exposing a photosensitive germanium-doped silica fiber to an intense UV laser beam. FBGs, in the basic form, can sense strain and temperature. However, in recent years, several newer sensing applications of FBGs have been demonstrated. Some of the main features of the FBG sensor which qualify them for diverse sensing applications are high sensitivity, large operational bandwidth, multiplexing & multi modal sensing capability, etc.
In this thesis work, FBG sensor based devices have been developed for newer applications in bio-medical fields for the measurement of force, flow and temperature.
Particularly, novel transduction methodologies have been proposed, in order to convert the measurand parameter into a secondary parameter that can be sensed by the FBG sensor.
The evaluation of the force required for a spinal needle to penetrate various tissue layers from skin to the epidural space is vital. In this work, a novel technique for dynamic monitoring of force experienced by a spinal needle during lumbar puncture using Fiber Bragg Grating (FBG) sensor has been developed. The Fiber Bragg Grating Force Device (FBGFD) developed, measures the force on the spinal needle due to varied resistance offered by different tissue layers during its traversal.
The effect of gauge of the spinal needle used for the lumbar puncture procedure affects the force required for its insertion into the tissue. The FBGFD developed, has been further utilized for a comparative study of the force required for lumbar puncture of various tissue layers with spinal needle of different gauges. The results obtained may serve as a guideline for selection of suitable gauge spinal needle during lumbar puncture minimizing post puncture side effects on patients.
The pulmonary function test carried out using a spirometer, provides vital information about the functional status of the respiratory system of the subject. A Fiber Bragg Grating Spirometer (FBGS) has been developed which has the ability to convert the rate of air flow into a shift in wavelength that can be acquired by the FBG sensor. The FBGS can dynamically acquire the complete breathing sequence comprising of the inhalation phase, pause phase and exhalation phase in terms of the air flow rate along with the time duration of each phase. Methods are adopted to analyse and determine important pulmonary parameters using FBGS and compare these parameters with those obtained with a commercially available hospital grade pneumotachograph spirometer.
Thermal imaging is one of the emerging non-invasive neuro-imaging techniques which can potentially indicate the boundaries of a brain tumor. The variation in tissue surface temperature is indicative of a tumor existence. In this work a FBG temperature sensor (FBGTS) has been developed for thermography of a simulated tissue using Agar material. The temperature of the embedded heater which mimics a brain tumor along with the surface temperature of the tissue model, is acquired using FBGTSs simultaneously. Further, the surface temperatures are studied for varying heater temperatures as well as varying positions of the heater in the simulated tissue model.
To conclude, FBG based devices have been developed in this work, for applications in biomedical domain, with appropriate transduction methodologies for sensing different parameters such as force, flow and temperature.

Previous issue date: 2009-06-30 / Financiadora de Estudos e Projetos / The formation of equivalent stimuli classes is a psychological phenomenon that has important characteristics for the experimentation of processes involving symbolic behavior acquisition. This kind of behavior has been the target of a wide variety of contemporary studies which have also demonstrated the possibility of such approach to generate symbolic behavioral repertoires based only on the teaching of some relations between stimuli. It is vital to investigate the parameters that optimize the establishment of equivalent stimuli classes desired by the researcher when defining the behavior to be installed through the procedure of matching-to-sample (MTS). Studies in the area have widely shown that after training A1B1 and B1C1, there is an emergency of some relations, such as B1A1, C1B1, A1C1 and C1A1, which demonstrate, respectively, the properties of reflexivity, symmetry, transitivity and equivalence. One of the parameters that determine the effectiveness of a procedure on class formation is the type of control relation exercised by the comparison stimuli in MTS attempts. Therefore, the present study aimed to identify the role of specific types of training of conditional discriminations in the establishment of relations of control for selection and rejection. Study participants were two teenagers with Down syndrome. The training consisted on MTS sessions with and without mask in two training types: non-nodular and nodular. The former occurred by presenting stimuli which function was either model or comparison only, and the latter was characterized by presenting stimuli with dual function, i.e. model and comparison simultaneously. Verification testing of the control relations established at baseline was made after non-nodular training and after nodular training, and only then verification testing of behavioral emergency was made. Two stimuli sets involved attempts with mask, while other two consisted of attempts without a mask. The experiment was specifically designed in a way that the training of a stimuli set with mask has occurred almost simultaneously with the training of a stimuli set without mask. Thus, the influence of historical undesirable variables was avoided on deductions made from performance comparison of the two different attempts (with or without mask). Results demonstrated, generally, that the training procedure used was very effective in teaching and formation of classes, what made difficult even to compare the greater effectiveness of the procedures with or without use of mask in the training of conditional relations. It is suggested the replication of this study, with a larger number of participants of this same population, so that it is possible to evaluate the data generality. / A formação de classes de estímulos equivalentes é um fenômeno psicológico que possui características importantes para a experimentação de processos relacionados à aquisição do comportamento simbólico. Esse tipo de comportamento tem sido alvo de uma grande variedade de estudos contemporâneos que tem demonstrado, inclusive, a possibilidade desse tipo de abordagem em gerar repertórios comportamentais simbólicos com base no ensino de apenas algumas relações entre estímulos. É de fundamental importância investigar os parâmetros que aperfeiçoam o estabelecimento das classes de estímulos equivalentes desejadas pelo pesquisador, ao definirem o comportamento instalado por meio do procedimento de matching-to-sample (MTS). Estudos da área verificaram amplamente que, após o treino de A1B1 e B1C1, há emergência de algumas relações, tais como, B1A1, C1B1, A1C1 e C1A1, que demonstram, respectivamente, as propriedades de reflexividade, simetria, transitividade e equivalência. Um dos parâmetros que determinam a efetividade de um procedimento na formação de classes é o tipo de relação de controle exercido em tentativas de emparelhamento com o modelo. A partir disso, o presente estudo teve como objetivo identificar o papel de tipos específicos de treino de discriminações condicionais no estabelecimento de relações de controle por seleção e rejeição. Participaram do estudo dois jovens com síndrome de Down. O treino consistiu em sessões de MTS com e sem máscara, aonde houve treinos dos tipos não nodular, com um estímulo apresentando função única de modelo ou de comparação exclusivamente, e houve também treino do tipo nodular, caracterizado por estímulos com dupla função, ou seja, modelo e comparação simultaneamente. Os testes de verificação das relações de controle estabelecidas na linha de base foram feitos após o treino não nodular, em seguida, após o treino nodular, e só então os testes de verificação de emergência comportamental foi aplicado. Duas estruturas envolveram tentativas com máscara, enquanto as outras duas estruturas constituíram-se de tentativas sem máscara. O desenho experimental foi especificamente planejado para que, o treino de uma estrutura de treino com máscara ocorresse quase simultaneamente com o de uma estrutura sem máscara. Desse modo, evitou-se o papel de variáveis históricas indesejáveis para a inferência derivada da comparação do desempenho nos dois tipos diferentes de estruturas e tentativas. Os resultados mostraram, de um modo geral, que o procedimento de treino empregado foi bastante eficiente no ensino e formação de classes, o que dificultou, inclusive, a comparação da maior efetividade do procedimento com ou sem uso de máscara no treino das relações condicionais. Sugere-se que o estudo, embora extenso no que diz respeito ao ensino e teste de relações, considerando ainda o tipo de população envolvida, seja replicado com um número maior de participantes para que a generalidade dos dados seja avaliada.

Variaciones sobre la Bye House de John HejdukBarberá Pastor, Carlos 20 May 2014 (has links)
El objeto de estudio del trabajo titulado Variaciones sobre la Bye House de John Hejduk es la casa Wall House 2; proyectada entre 1972 y 1974 para la ciudad de Ridgefield, en Connecticut (U.S.A), y construida sobre el año 2000 en la ciudad de Groningen, en Holanda.
Se dedican dos capítulos para analizar la Wall House a partir del material publicado en Mask of Medusa y Five Architects. Los capítulos se titulan "Presentación de la Wall House 2 (Bye House) de John Hejduk" y "Una visita a la Wall House 2 de papel". En estos dos apartados, se pone en orden la información sobre la Wall House disponible en los documentos.
En estos dos primeros capítulos la casa, de papel, es visitada a través de los libros donde aparece el proyecto.
En el capítulo tercero, "Una visita a la Wall House 2 construida en Groningen", se describe la visita a la casa construida en Holanda. Se comparan las explicaciones sobre la experiencia en el interior de la casa con algunas explicaciones que Hejduk da sobre la experiencia arquitectónica. Se considera que la casa surge de un proyecto y de un proceso que la origina.
En el capítulo 4, titulado "La Wall House 2 como instrumento musical", se compara el proyecto de la Wall House con algunos dibujos sobre instrumentos musicales que Hejduk plantea a los estudiantes de la Escuela de Arquitectura de New York. En este capítulo se introduce la concepción de la casa como un instrumento musical. Es, en parte, un prólogo al planteamiento de la tesis doctoral, es un preludio a la exposición, donde la Wall House empieza a presentarse desde la particularidad de la casa al compararla con la música.
El capítulo siguiente analiza las relaciones que vinculan el proceso de la transformación de un cuadrado, sobre el cual se fundamenta la casa, con otros proyectos anteriores, como son las Texas Houses, las Diamond Houses y otras Wall Houses.
El último capítulo, "La Casa para el Habitante que se Negó a Participar en la Wall House 2", es una continuación del anterior / Barberá Pastor, C. (2009).

Nebezpečná metoda 19 / The Dangerous Method # 19Staněk, Jiří Unknown Date (has links)
I'm working with photographs of Sigmund Freud's apartment and creating their pseudo reconstruction. I'm trying through technique of linocut uncover light from black and white photos taken by documentarist Edmund Engelman in Vienna in 1938. I'm revealing volumes of individual fragments, which light falls on. Exposed light I keep for myself, for some melancholy reasons, and store it in glass jars. It is negative and final linocut represents positive. Atmosphere of pictures from Edmund Engelman's book has a big influence on me as well as Robert Longo's cycle Freud Drawings. Their atmosphere is catalyst for my own art solution.

Kirurgiskt munskydd : En förstudie kring material, konstruktion och återanvändbara möjligheter / Surgical face mask : A feasibility study on materials, construction and reusable possibilitiesStröm, Sara, Svenson, Julia January 2020 (has links)
I december 2019 rapporterades de första fallen av ett virus benämnt som covid-19 i Wuhan, Kina. Viruset sprider sig snabbt och i takt med den okontrollerade spridningen blir också trycket på sjukvården allt högre. Samtidigt som vården gör allt i sin makt för att räcka till så rapporteras det om global brist på skyddsutrustning. Tillverkningen av ett kirurgiskt munskydd, från fiber till färdig produkt, består av ett omfattande system och kräver material av specifika fibrer som framställs i avancerade processer. Att skapa ett munskydd som besitter möjligheten för återanvändning hade varit ett alternativ i syfte att minska risk för att munskydd tar slut samtidigt som engångsförbrukning minimeras. Syftet med denna studie är att studera och analysera materialval, framställning, konstruktion och krav för kirurgiska munskydd. Studien syftar också till att undersöka alternativa möjligheter till att skapa ett återanvändbart munskydd. Val av metod för insamling av material har haft sin utgångspunkt i litteraturstudier av främst vetenskaplig karaktär. Då ämnet är högaktuellt har nyhetsartiklar från betrodda dagstidningar varit av värde. Intervjuer av kvalitativ läggning genomfördes i syfte att skapa en överskådlig inblick i vårdarbetet. Ett kirurgiskt munskydd fungerar som en skyddande barriär mot överföring av smittämnen mellan personal och patient och är generellt uppbyggt i tre olika lager. Det inre lagret, mittenlagret, är tillverkat genom en process kallad nonwoven meltblown medan de två yttre lagren, det övre och det undre, tillverkas genom en process kallad nonwoven spunbond. Dessa tre lager kalendreras sedan samman och bildar själva filtermediet som därefter veckas och sys i en konverteringslinje. Munskydd är en engångsvara och slängs direkt efter användning. Nawar Kadi, som är professor på Textilhögskolan i Borås, arbetar för tillfället med ett projekt som syftar till att utveckla ett delvis tvättbart munskydd som fungerar att återanvända. I dagsläget finns många aspekter att beakta och frågor att besvara innan projektet går att förverkliga i praktiken men med rätt förutsättningar, ekonomisk stöttning och framförallt beprövade metoder med bakomliggande forskning är möjligheten till att skapa ett återanvändbart munskydd inte långt borta. / In December 2019, the first cases of a virus called covid-19 were reported in Wuhan, China. The virus is spreading rapidly and in connection with the uncontrolled spread, the pressure on healthcare is also increasing. At the same time as healthcare is doing everything in its power to suffice, a global lack of protective equipment is reported. The manufacture of a surgical face mask, from fiber to finished product, consists of a comprehensive system and requires materials of specific fibers produced in advanced processes. Creating a face mask that possesses the possibility of reuse would have been an alternative with the aim of reducing the risk of face mask ending while minimizing disposable consumption. The purpose of this study is to analyze material selection, manufacture, construction and requirements for surgical face masks. The study also aims to explore alternative ways of creating a reusable face mask. The choice of method for collecting material has been based on literature studies of a primarily scientific nature. As the topic is highly current, news articles from trusted newspapers have been of value. Qualitative interviews were conducted with the aim of providing a clear insight into the healthcare work. A surgical face mask serves as a protective barrier against the transmission of infectious agents between staff and patients and is generally constructed in three different layers. The inner layer is made by a process called nonwoven meltblown, while the two outer layers, the upper and the lower, are made by a process called nonwoven spunbond. These three layers are then calendered together to form the filter media, which is then pleated and seamed in a converting line. The surgical face mask is a disposable item and is discarded immediately after use. Nawar Kadi, who is a professor at Textilhögskolan in Borås, is currently working on a project aimed at developing a partially washable face mask that thus functions to reuse. At present, there are many aspects to consider and questions to answer before the project can be realized in practice but with the right conditions, financial support and proven methods with underlying research, the possibility of creating a reusable face mask is not far away.

Ultra precision metrology : the key for mask lithography and manufacturing of high definition displaysEkberg, Peter January 2011 (has links)
Metrology is the science of measurement. It is also a prerequisite for maintaining a high quality in all manufacturing processes. In this thesis we will present the demands and solutions for ultra-precision metrology in the manufacturing of lithography masks for the TV-display industry. The extreme challenge that needs to be overcome is a measurement uncertainty of 10 nm on an absolute scale of more that 2 meters in X and Y. Materials such as metal, ceramic composites, quartz or glass are highly affected by the surrounding temperature when tolerances are specified at nanometer levels. Also the fact that the refractive index of air in the interferometers measuring absolute distances is affected by temperature, pressure, humidity and CO2 contents makes the reference measurements really challenging. This goes hand in hand with the ability of how to design a mask writer, a pattern generator with a performance good enough for writing masks for the display industry with sub-micron accuracy over areas of square meters. As in many other areas in the industry high quality metrology is the key for success in developing high accuracy production tools. The aim of this thesis is therefore to discuss the metrology requirements of mask making for display screens. Defects that cause stripes in the image of a display, the so called “Mura” effect, are extremely difficult to measure as they are caused by spatially systematic errors in the mask writing process in the range of 10-20 nm. These errors may spatially extend in several hundreds of mm and are superposed by random noise with significantly higher amplitude compared to the 10-20 nm. A novel method for measuring chromium patterns on glass substrates will also be presented in this thesis. This method will be compared to methods based on CCD and CMOS images. Different methods have been implementedin the Micronic MMS1500 large area measuring machine, which is the metrology tool used by the mask industry, for verifying the masks made by the Micronic mask writers. Using alternative methods in the same system has been very efficient for handling different measurement situations. Some of the discussed methods are also used by the writers for calibration purposes. / QC 20110517
