Organic electronics has evolved into a well-established research field thanks to major progresses in material sciences during recent decades. More attention was paid to this research field when “the discovery and development of conductive polymers” was awarded the Nobel Prize in Chemistry in 2000. Electronic devices that rely on tailor-made material functionalities, the ability of solution processing and low-cost manufacturing on flexible substrates by traditional printing techniques are among the key features in organic electronics. The common theme while exploring organic electronics, and the focus of this thesis, is that (semi-)conducting polymers serve as active materials to define the principle of operation in devices. This thesis reviews two kinds of organic electronic devices. The first part describes electrochemical devices based on conducting polymers. Active matrix addressed displays that are printed on flexible substrates have been obtained by arranging electrochemical smart pixels, based on the combination of electrochemical transistors and electrochromic display cells, into cross-point matrices. The resulting polymer-based active-matrix displays are operated at low voltages and the same active material is used in the electrochemical transistors as well as in the electrochromic display cells, simply by employing the opto-electronic properties of the material. In addition to this first part, a switchable optical polarizer based on electrochromism in a stretch-aligned conducting polymer is described. The second part reports switchable charge traps in polymer diodes. Here, a device based on a solid-state blend of a conjugated polymer and a photochromic molecule has been demonstrated. The solid state blend, sandwiched between two electrodes, provide a polymer diode that allows reversible current modulation between two different charge transport mechanisms via externally triggered switching of the charge trap density.

The aim of this research was to study a novel, broadband, low cost, low profile and a high-medium gain antenna in the UHF band. This has been achieved through numerical modelling, theoretical investigation and physical measurements. In this study two commercially available antenna systems are investigated in order to compare and establish potential deficiencies in the UHF antenna systems. A number of disadvantages are resolved within a novel antenna system design. The parametric study is performed for each element of the novel antenna system in order to optimise its overall performance. The indoor and outdoor measurements have been carried out in house, in order to validate the predicted results. The novel antenna system is compared to the most popular and commercially available UHF antenna systems. The study demonstrates that the novel antenna system has clear advantages such as broadband, balanced, compact and low cost when compared to the commercial antenna designs studied here. The comparison of the manufacturers' data to the measured results shows a good match, validating the outdoor measurements technique used in this research.

This diploma thesis deals with the influence of teenage girl magazines and school on the self-concept of adolescent girls. Theoretical part aims to bring comprehensive review of current scientific research on the topic of development of self-identity during adolescence where self-concept is created with strong emphasis on physical appearance. The thesis subsequently examine possible disorders that can arise from erroneous self-concept.

This diploma thesis deals with the everyday life of journalists between years 1970 - 1990. It is divided into a theoretical and a practical part. The theoretical part draws mainly from books on sociology, Statistics Office and publications and journals of "The Journalist" ("Novinář") publishing. There are definitions of the key terms and statistic data on media, culture and life style in the first part. It also depicts Czech society in the time of Normalization, as well as professional and social structure of the population, scholar-ship and the position of a journalist in this era. The practical part is devoted to the interviews with journalists and analyses separate aspects of everyday life. This analysis was made with the usage of the qualitative method and compares particular responses of the journalists with the data from the theoretical part.

Orientador: Nelyse Apparecida Melro Salzedas / Banca: Rozinaldo Antonio Miani / Banca: Maria Lúcia Vissotto Paiva Diniz / Resumo: Subjetividade, crônica, ilustração, jornalismo impresso e produção de sentido. O que esses termos têm em comum? Mais do que apresentar uma opinião pessoal, a crônica e a ilustração, frutos de uma indústria cultural que chega ao Brasil em meados do século XX, influenciam outra visão social, uma vez que se caracterizam pela busca incessante em captar um momento da realidade e interpretá-lo por meio do texto ou do traço. Os meios de comunicação atraem a atenção do leitor pelas diferentes maneiras de informar ou comentar uma notícia. Ao longo da evolução do jornalismo impresso, colunas de informação foram adaptadas ao jornal e o uso da ilustração passou a ser um recurso utilizado para produção de sentido na realidade. Tão subjetiva quanto as crônicas, editoriais e comentários, a ilustração hoje é empregada diariamente no meio impresso, devido ao avanço proporcionado pelas novas tecnologias e também pela boa recepção que obteve junto ao público leitor que cada vez mais consume imagens. A partir dessa perspectiva, temos a inegável importância de se estudar a relação entre o texto e a imagem para compreendermos a implicação do verbal e do não verbal através das novas propostas de comunicação. Na presente dissertação, verificaremos a produção de sentido entre determinadas crônicas de Arnaldo Jabor e ilustrações de Cido Gonçalves publicadas no Caderno 2 do jornal O Estado de S. Paulo entre 2006 e 2007. Analisaremos as mesmas como manifestações de uma indústria cultural consolidada e ainda forte. Verificar a relação texto e imagem é o objetivo principal a que nos propomos, refletindo sobre a importância da crônica e da ilustração no meio impresso. Pretendemos analisar as crônicas selecionadas averiguando como essas superam a efemeridade das notícias utilizando outros referenciais para situar os constantes conflitos sociais.

More than presenting a personal opinion, chronics and illustrations, offspring of a cultural industry that arrives in Brazil in the beginning of the 20th century, influence other social vision, once they are characterized by a restless search to capture a moment of reality and interpret it through text or illustration. The means of communication attracts the reader's attention through different ways of informing or commenting a piece of news. During the evolution of printed journalism, columns of information were adapted to the newspaper and the use of illustration started being a resource used in the construction of a new production of meaning over the reality. As subjective as the chronics, editorials and comments, the illustration is used nowadays in a daily basis in the printed media, due to the evolution enabled by the new technologies and also by the good acceptance which received along to the readers which more and more consumes images. From this perspective, there is the undeniable importance of studying the relationship between text and image to understand the implication of the verbal and non-verbal through the new propositions of communication. In the present dissertation, we are going to check the production of meaning among determined chronics by Arnaldo Jabor and the illustrations of Cido Gonçalves published in Caderno 2 of the O Estado de S. Paulo newspaper between 2006 and 2007. We will analyze them as manifestations of a consolidated and strong cultural industry. Checking the relationship between text and image is the main objective proposed, reflecting over the importance of chronics and illustration in the printed media. We intend to analyze the selected chronics noticing how they overcome the ephemerity of the news using other referentials to site ...(Complete abstract click electronic address below) / Mestre

La thèse s’inscrit dans le cadre du projet de recherche collaborative VEADISTA (Veille à distance et alerte intelligente) qui repose sur la conception d’une technologie ergonomique à bas coût. L’objectif de cette thèse est de concevoir et de réaliser des capteurs de température et de pression imprimés sur support flexible pour des applications biomédicales. Ils doivent être adaptés à une intégration sur un transpondeur passif télé-alimenté, conformables pour s’adapter au bras du patient, bas coût et permettant un transfert technologique vers l’industrie.Des prototypes de tests ont été réalisés dans le but d’identifier la topologie et la couche active les plus prometteuses pour la réalisation des capteurs de température en tout imprimé sur support souple. A l’issue de cette étude préliminaire, une thermorésistance à base d’encre d’argent a été réalisée par jet d’encre sur un substrat flexible. La caractérisation de ces capteurs a permis d’évaluer leur sensibilité et d’attester de leur bonne linéarité.Des tests préliminaires sur des capteurs commerciaux ont ensuite été effectués pour démontrer qu’il était possible de détecter le rythme cardiaque avec un capteur de pression. A la suite de cette étude, des capteurs de pression sur support souple ont été fabriqués en utilisant la technologie jet d’encre. Ces capteurs ont été caractérisés électriquement sous contrainte mécanique contrôlée. Pour aboutir à ces résultats, de nombreux développements technologiques ont été réalisés autour de la technique d’impression par jet d’encre. La maîtrise du triptyque encre-tête d’impression-substrat est en effet indispensable pour l’obtention de motifs de qualité. / This thesis is a part of the collaborative research project VEADISTA (Remote monitoring of vital parameters and smart alerts) based on the conception of an ergonomic technology at low-cost.The objective of this thesis is to design and to realize printed temperature and pressure sensors on flexible support for biomedical applications. Subsequent to this, these sensors must be suitable to an integration on a passive transponder remotely powered, conformable to fit the patient's arm, low cost and allowing a technological transfer towards industry.Prototype tests were realized in order to identify the most promising topology and active layer to achieve printed temperature sensors on flexible support. At the end of this preliminary study, a RTD based on a silver ink was performed by inkjet on a flexible substrate (Kapton). The characterization of these sensors allowed to assess their sensitivity and to attest to their good linearity.The preliminary tests on commercial sensors were then made to demonstrate that it was possible to detect the heart rate with a pressure sensor. Following this study, pressure sensors were manufactured on flexible support using inkjet technology. These sensors were electrically characterized under controlled mechanical constraint. To achieve these results, many technological developments were realized around the inkjet printing technique. The mastery of the ink – inkjet head – substrate interaction is indeed essential for obtaining good printed quality and functional sensors.

A indústria têxtil brasileira viveu seu apogeu econômico nas décadas de 1950, 1960 e 1970. Seus expressivos números, associados ao clima eufórico nacionalista, contribuíram para transformar esse setor num segmento importante para a consolidação de sentidos acerca da existência de uma identidade nacional, que se teria dado por meio da produção de estampas genuinamente brasileiras. Com base nessa hipótese, esta pesquisa dedica-se a explorar o processo de produção de sentidos nacionalistas e patrióticos implantados e difundidos por imagens, tendo como metodologia principal a investigação dos processos internos da indústria e a observação da divulgação dada à atuação da indústria têxtil naquele período. Procura-se comprovar que os sentidos produzidos foram decorrentes bem mais de um discurso eficiente do que de uma criação autêntica ou genuína que tenha havido nesse setor. / The Brazilian textile industry reached its apogee in the period 1950-1970. The widespread impact it made in a climate of euphoric nationalism, led to this sector being turned into a means of strengthening feelings about the existence of a particular Brazilian national identity, which it achieved by producing printed designs that were genuinelyBrazilian. On the basis of this supposition, this research project is devoted to exploring the way nationalistic and patriotic feelings have been instilled and spread through images, by employing a methodology that mainly involves investigating the inner processes of industrialisation and the observation of the promotion of the textile industry in that period. The study seeks to support the view that the feelings that have been evoked, arise more from an effective discourse than any authentic or genuine creation that has taken place in this sector.
