Film of assembly of sonic and imaginary elements, symbiotic and amalgamated, that transit between temporalities and localities producing memory of the latin american cinema of the years of the 60s and 70s. Memory that is not a subject or a whole movement, but immemorial, absolute and involuntary as the contact of a self and a world. In the movement of looking at the past and dialoguing with it, the files that constitute the film are updated in the present. Archives of Havana, Glauber Rocha, Latin American cinema, and aesthetic and political dimensions tensioned and in relation to the cinematographic language and with the established settlements with the world. Through bibliographical research and a film analysis, we seek to understand how the traces of images (visual and sound) are mobilized by the experience of the filmmaker and performed by the montage At first, we seek to contextualize the film within the context of Brazilian contemporary documentary and to approach it with the concept of filmessay, conceiving the essaistic gesture as the guide of our process of film analysis and bibliographic research. Next, we discuss the appropriation of archives and the unrelated relations of images with memory and history. The poetic-constructive operation of the montage marked by the heterogeneity of materials and their new combinations gains prominence in the figure of the palimpsest that summons in form and gesture the aporia of a past that is not over but still, and continues to be updated in the present. / A pesquisa busca analisar o pensamento ensaístico, o gesto da operação da montagem e a produção de memória no filme-ensaio Rocha que Voa (2002), do cineasta brasileiro Eryk Rocha. Filme de montagem de elementos sonoros e imagéticos, simbióticos e amalgamados, que transitam entre temporalidades e localidades produzindo memória do cinema latino-americano dos anos das décadas de 60 e 70. Memória essa não apenas de um sujeito ou de um movimento todo, mas memória imemorial, absoluta e involuntária enquanto contato de um eu e de um mundo. No movimento de olhar o passado e com ele dialogar, os arquivos que constituem o filme se atualizam no presente. Arquivos de Havana, de Glauber Rocha, do cinema latino-americano, e de dimensões estéticas e políticas tensionadas e em relação com a linguagem cinematográfica e com os agenciamentos estabelecidos com o mundo. A partir da pesquisa bibliográfica e de uma análise fílmica ensaística, buscamos compreender como a forma do filme-ensaio é modulada e como os vestígios de imagens são mobilizados pela experiência fílmica do cineasta. A princípio, buscamos contextualizar o filme no âmbito do documentário contemporâneo brasileiro e aproximá-lo do conceito de filme-ensaio, percebendo seus contornos e camadas que se formam ao conceber o pensamento ensaístico como o norteador de nosso processo de análise fílmica. Em seguida, discutimos a as relações imbrincadas das imagens com a memória e a história possibilitadas pela montagem. A operação poética-construtiva da montagem marcada pela heterogeneidade de materiais e correspondências ganha destaque na figura do palimpsesto que convoca em forma e gesto a aporia de um passado que não foi, mas que é, e que continua se atualizando no presente.

Fraturas da metrópole. Objetividade e crise do romance em Berlin Alexanderplatz / Fractures of the metropolis: Objectivity and the crisis of the novel Berlin Alexanderplatz

Gabriela Siqueira Bitencourt 21 June 2010 (has links)
Publicado em 1929, o romance Berlin Alexanderplatz de Alfred Döblin foi considerado, desde as primeiras resenhas, um marco na literatura alemã. Sua novidade residia, sobretudo, na utilização das técnicas da colagem e da montagem, por meio das quais os fragmentos recolhidos da metrópole foram inseridos no romance como sua própria matéria formal. Döblin tentou, com isso, deslocar o espaço concedido à metrópole, de objeto de representação a sujeito da enunciação. Essa dissertação analisa a composição formal de sua narrativa para compreender o que o novo espaço angariado pela metrópole, em Berlin Alexanderplatz, implica para o gênero. Esse problema dialoga diretamente com a importante discussão da \"crise do romance\", que animava os debates de então sobre literatura e encontrava franca ressonância também na produção teórica de Döblin, desenvolvida entre 1910 e 1930. Contrapor Berlin Alexanderplatz às questões levantadas nesses textos teóricos torna ainda mais explícita a relação da obra com seu próprio tempo. Ademais, há uma estrita coincidência entre a importância da objetividade em boa parte da teoria de Döblin e os pressupostos do movimento artístico mais característico dos anos da República de Weimar, a Neue Sachlichkeit. Examinar essa convergência ajuda a iluminar os problemas de uma narrativa que oscila, dialeticamente, entre a representação do destino individual e busca uma montagem realista da metrópole. Todos esses diálogos, além do confronto com a tradição do gênero, ajudam a entrever alguns dos elementos que levaram à configuração, nas palavras de Döblin, dessa \"épica da modernidade\". / Published in 1929, Berlin Alexanderplatz, a novel by Alfred Döblin, was considered - since its first reviews - a landmark in German literature. Its novelty resided above all in the use of the techniques of collage and montage, the use of which made possible that fragments collected in the metropolis could be inserted in the novel as its own formal matter. What Döblin has tried to do with that was to displace the position usually afforded to the metropolis, from object of representation to subject of enunciation. This dissertation engages in an analysis of the narrative formal composition in order to understand what this new position - conquered by the metropolis in Berlin Alexanderplatz - implies to the genre. This problem is in constant dialogue with the very important \"crises of the novel\" issue, which supported much of the literary debate of the time and has a corresponding development in Döblin\'s own theoretical production from 1910 to 1930. Contrasting Berlin Alexanderplatz to the questions posed in these theoretical texts makes the relationship of the novel with its own time even more explicit. Moreover there is a strict coincidence between the importance of objectivity in a good deal of Döblin\'s theory and the presuppositions of the most characteristic artistic movement of the Weimer Republic, the Neue Sachlichkeit. To examine this convergence helps us cast some light on the problems of a narrative that dialectically oscillates between the representation of an individual destiny and the search for a realist montage/image of the metropolis. All this dialogues, besides the confrontation with the novel tradition, help us glimpse some of the elements that headed towards the configuration of this, in Döblin\'s own words, \"epic of modernity\".

Sokúrov e a montagem em vida humilde (1997): imagem e representação / -

Breno Morita Forastieri da Silva 22 September 2015 (has links)
Da confluência entre o conceito de texto artístico de Iuri Lotman e a teoria do cinema intelectual de Sergei Eisenstein, este trabalho oferece uma análise do filme Vida humilde (1997) de Aleksandr Sokúrov. De estudos de Eisenstein sobre a lógica composicional do pensamento por imagens, foi compilado um conjunto de ferramentas analíticas a fim de se investigar a imagem geral do filme. Por meio de tais ferramentas, é investigada a relação entre a construção plástica do filme e a percepção da imagem de uma vida humilde. Ainda alinhada à teoria da montagem eisensteiniana, essa imagem é proposta como resultante intelectual de outras três imagens: as da circularidade, da harmonia e da homologia. Desta maneira o filme é esquadrinhado de maneira a salientar os elementos formais que possibilitam sua decodificação como qualidades abstratas. / Through the articulation between the concept of artistic text of Juri Lotman and the theory of intellectual cinema of Sergei Eisenstein, this work offers an analysis of the film Humble life (1997) of Aleksandr Sokurov. Eisenstein\'s studies on the compositional thought on the logic of images, gave rise to a compilation of analytical tools in order to investigate the overall image of the film. Thus, analyzing the relationship between the construction of the plastic film and the overall image of a humble life. Still aligned to Eisenstein\'s theory of montage, this image is proposed as an intellectual result from three other images: circularity, harmony and homology. In this way the film is scanned in order to emphasize the formal elements that enables us to decode it as abstract qualities.

Estudo experimental da migração eletroquímica em soldagem eletrônica Sn/Ag/Cu \"Lead Free\". / Experimental study of eletrochemical migration of electronic soldering Sn/Ag/Cu \"lead free\".

Luiz Tadeu Freire Mendes 10 June 2009 (has links)
Sabemos que em placas de circuito impresso montadas com tecnologia SMD Surface Mount Device podem ocorrer problemas com a migração eletroquímica. O fenômeno aparece principalmente porque os novos encapsulamentos possuem terminais com espaçamentos muito próximos. A migração eletroquímica pode tornar-se um potencial problema no processo de soldagem eletrônica quando é utilizado a tecnologia Lead Free na montagem das placas. O processo de migração eletroquímica ocorre quando temos metal, isolante e metal, em ambiente de alta umidade e sobre polarização elétrica, o metal deixa a posição inicial em forma de íon e se redeposita sobre o isolante. Em uma placa de circuito impresso, dois terminais adjacentes podem tornar-se eletrodos, dessa forma as dendritas crescem do cátodo para o ânodo. Podem aparecer diferentes morfologias com diferentes elementos envolvidos no processo de migração, dependendo da composição da pasta de solda ou acabamento da placa de circuito impresso. Uma estrutura do tipo pente comb feita sobre laminado FR4 foi utilizada nos experimentos. A distância entre as trilhas foram de 102 e 254 mícrons para simular uma distancia real dos terminais dos dispositivos. Os fatores considerados durante os experimentos foram: A distancia entre os terminais na estrutura (102 ou 254 mícrons), tensão aplicada (2 ou 3 V). Foi observado que a pasta de solda e o acabamento final não influenciam no processo de migração eletroquímica. O Estanho foi o principal metal que migrou. Todos os resultados obtidos nesse estudo concordam com a literatura. / It is well known that in printed circuits boards assembled by SMT technology may occur Electrochemical migration (ECM). This phenomenon appears mainly because the new packaging has the terminals very close. Also the Electrochemical migration may become a potential reliability problem in electronic soldering when lead free technology is used in soldering electronic devices. Electrochemical migration is an electrochemical process where metal on an insulating material, in a humid environment and under an applied electric field, leaves its initial location in ionic form and redeposit. In a PCB two adjacents terminal may behave as electrodes so the dendrites grow from cathode to anode. It can show different morphologies with the different migration elements involved depending on the solder paste composition or PCB surface finishing. A structure with a comb shape printed on FR4 substrate was used in the experiments. The distance between the fingers in the structure was 102 or 254 microns, in order to simulate a real distance between dispositive terminals. The factors considered during the experiments were surface finishing (ENIG or HASL), solder paste composition, distance between terminals (102 or 254 microns) and applied voltage (2 or 3 V). It was observed that the solder paste and the surface finishing dont influence the ECM process. Tin was the main metal that migrates. All the results obtained in these study agrees with the literature.

Contribution à l'évaluation des efforts de coupe avec applications au fraisage de finition / Contribution to the evaluation of cutting forces with applications to finishing milling

Delahaye, Nicolas 21 May 2015 (has links)
L’usinage tient une place considérable dans l’industrie, c’est un des procédés les plus répandu. A ce titre, la maitrise du procédé de fraisage, notamment lors d’une opération de finition, est devenu un enjeu majeur dans le secteur industriel. La compréhension des phénomènes physiques présents lors d’un usinage de finition est un facteur important pour l’optimisation d’un procédé de fabrication par enlèvement de matière.Afin de déterminer les paramètres influents lors d’un usinage de finition, notamment lors d’un fraisage de profil, une nouvelle méthodologie expérimentale sera développée. Ces travaux vont s’articuler autour de trois activités principales :- La mise en place d’une instrumentation capable de recueillir une image des efforts de coupe. Ce dispositif expérimental devra être équipé de capteurs et d’une chaine d’acquisition pour acquérir les composantes des efforts selon les directions x et y.- Le développement d’un nouveau dispositif passe par une étape qualification dans laquelle une série de tests permettra d’établir la capabilité du montage.- Cette étude expérimentale s’accompagne d’une campagne d’essais permettant de définir les paramètres les plus influents lors d’un fraisage de profil de finition. / Machining holds an important place in the industry, this is one the most common process. As thus, mastering the milling process, especially during a finishing operation, has become a major issue in the insdustrial sector. Understanding the physical phenomena present in a finishing machining is an important factor for the optimization of a manufacturing process by removing material.In order to determine the most important factors during a finishing machining, in particular during a profile milling, a new experimental methodology will be developed. This work will focus on three main activities :- The introduction of instrumentation capable of collecting an image cutting forces. This experimental device must be equipped with sensors and an acquisition channel to acquire the components of the forces in the x and y directions.- The development of a new device going through a stage qualification in which a series of tests will establish the capability of experimental device.- This experimental study is accompanied by a series of tests to define the most important parameters in a finishing profile milling

Produktionsergonomische Bewertung der aktuellen Produktionslinie des Centerwave 6000

van Brackel, Lars 07 October 2019 (has links)
Die Gesundheit von Beschäftigten in Unternehmen wird unter dem Aspekt einer sich verändernden Altersstruktur und sich schneller wandelnden Arbeitsbedingungen zunehmend an innerbetrieblicher Bedeutung gewinnen. Sie ist einer der Schlüssel zur Erhaltung und Förderung der Arbeitsbewältigungsfähigkeit der Mitarbeiter und damit Arbeitsfähigkeit sowie die Leistungsbereitschaft auf der Lebensarbeitszeitachse zu erhalten und somit Kontinuität in einer manuellen Produktion zu erzeugen. Die vorliegende Masterarbeit beschäftigt sich mit der Analyse eines Montagearbeitsplatzes in einem mittelständischen Betrieb, hinsichtlich ergonomischer Belastungsfaktoren. Bei der analysierten Tätigkeit steht die physische Belastung aus Körperzwangshaltung und des Hand-Arm-Schulter Systems im Mittelpunkt, da dieses die wesentlichen Belastungsfaktoren sind. Ein weiterer Aspekt war, dass die hier untersuchte Arbeitsaufgabe eine sehr gute Ausgangsbasis schafft um Rückschlüsse auf die Fertigungs- und Montagebedingungen fast aller anderen Produkte zu ziehen. Die Arbeit gibt somit nicht nur Auskunft über die aktuelle ergonomische Belastung bei der Produktion des Centerwave 6000 und ihrer Verbesserungsmaßnahmen, sondern eröffnet auch die Perspektive einen generellen Gesundheitsgewinn zu erzielen, der auf der Minimierung von vergleichbaren ergonomischen Risikofaktoren in der gesamten Fertigung beruht.

Interaktive Initialisierung eines Echtzeit 3D-Trackings für Augmented Reality auf Smart Devices mit Tiefensensoren

Neges, Matthias, Siewert, Jan Luca January 2016 (has links)
Zusammenfassung Heutige Ansätze des 3D-Trackings für die Registrierung in der realen Welt zum Einsatz von Augmented Reality lassen sich in modellbasierte und umgebungsbasierte Verfahren unterteilen. Umgebungsbasierte Verfahren nutzen den SLAM-Algorithmus zur Erzeugung dreidimensionaler Punktwolken der Umgebung in Echtzeit. Modellbasierte Verfahren finden Ihren Ursprung im Canny edge detector und nutzen aus den CAD-Modellen abgeleitete Kantenmodelle. Wird das modellbasierte Verfahren über Kantendetektion und das umgebungsbasierte Verfahren über 3DPunktewolken kombiniert, ergibt sich ein robustes, hybrides 3D-Tracking. Die entsprechenden Algorithmen der verschiedenen Verfahren sind in heute verfügbaren AR-Frameworks bereits implementiert. Der vorliegende Betrag zeigt zwar, welche Effizienz das hybride 3D-Tracking aufweist, jedoch auch die Problematik der erforderlichen geometrischen Ähnlichkeit von idealem CAD-Modell, bzw. Kantenmodell, und realem Objekt. Bei unterschiedlichen Montagestufen an verschiedenen Montagestationen und mit wechselnden Anwendern ist beispielsweise eine erneute Initialisierung erforderlich. Somit bedingt das hybride 3D-Tracking zahlreiche Kantenmodell, die zuvor aus der jeweiligen Montagestufe abgeleitet werden müssen. Hinzu kommen geometrische Abweichungen durch die Fertigung, die je nach Größe der branchenspezifischen Toleranzen keine hinreichend hohe Übereinstimmung mit den abgeleiteten Kantenmodellen aus den idealen CAD-Modellen aufweisen. Die Autoren schlagen daher den Einsatz parametrisch aufgebauter Mastermodelle vor, welche durch eine interaktive Initialisierung geometrisch Instanziiert werden. Zum Einsatz kommt hier ein mobiler Tiefensensor für Smart Devices, welcher mit Hilfe des Anwenders eine Relation der realen geometrischen Merkmale mit den Idealen des CAD-Modells ermöglicht. Des Weiteren wird in dem dargestellten Konzept die Nutzung von speziellen Suchalgorithmen basierend auf geometrischen Ähnlichkeiten vorgeschlagen, sodass eine Registrierung und Instanziierung auch ohne hinterlegtes Mastermodell ermöglicht wird. Der Beitrag fokussiert sich bei der Validierung auf die interaktive Initialisierung anhand eines konkreten anwendungsnahen Beispiels, da die Initialisierung die Grundlage für die weitere Entwicklung des Gesamtkonzeptes darstellt.

Animated Memories : A case study of the animated documentary 'Saydnaya – Inside a Syrian Torture Prison' (2016) and its potential within social memory

Scheuermann, Melina January 2019 (has links)
Through its ability to create images of non-representable incidents animation expands the range and depth of what documentary can represent and how. This master thesis investigates the potential of animated documentary within social memory exemplified by the interactive animated documentary Saydnaya – Inside a Syrian Torture Prison (Forensic Architecture, 2016). By applying a feminist spatial approach, I aim to contribute to the understanding of the role of animated documentary images within social memory.Embodied and haptic spectatorship as well as haptic materiality are crucial in this case study due to the nature of the virtual screen images and interactive navigation (compared to montage) of the architectural 3D model. Testimonies and evidence presented in documentary film require a discursive establishment of truth. Indexicality is discussed in this regard and eventually a theoretical shift towards movement suggested. I demonstrate that Saydnaya extends the strategies in animated documentary that have been in focus so far, such as representing mental states and subjective experiences, by deploying methods of forensic aesthetics. This opens up novel ways to establish truth claims and persuasion in documentary filmmaking that require future research.

[en] GETTY IMAGES: MONTAGE, CONTROL AND CREATIVE CONSTRUCTION FROM AN AUDIOVISUAL DATABASE / [pt] GETTY IMAGES: MONTAGEM, CONTROLE E CONSTRUÇÃO CRIATIVA A PARTIR DE BANCO DE DADOS AUDIOVISUAL

GUILHERME BENTO DE FARIA LIMA 26 October 2020 (has links)
[pt] Esta tese realiza análise crítica da Getty Images a fim de compreender atualizações de procedimentos de vigilância e controle perpetrados no campo da publicidade. Parte-se da arqueologia das mídias em busca por especificidades do banco de dados audiovisual para compreender protocolos próprios do ambiente virtual organizados a partir da lógica da invisibilidade. Através da análise semiótica de cinco filmes publicitários produzidos para marca pela agência publicitária brasileira, AlmapBBDO, é possível identificar de forma mais aprofundada estratégias de comunicação de valores e princípios da Getty Images. Em consonância com técnicas de montagem, diálogo com linguagem fragmentada e a partir da reapropriação de conteúdo audiovisual são produzidos pequenos vídeos-ensaios que visam revisitar e explorar paradigmas da imagem, bem como contribuir na reflexão do potencial latente dos bancos de dados audiovisual. Concomitantemente, é apresentada a perspectiva de construção criativa de monstros como estratégia publicitária cada vez mais recorrente como etapa da produção audiovisual. Além disso, é desenvolvida uma aproximação entre técnicas cinematográficas e publicitárias que busca sublinhar hibridismos e possíveis interconexões entre as duas áreas. Por fim, são apresentados exemplos que apontam possíveis utilizações da publicidade como forma de resistência e promotora de reflexão crítica diante de conjunturas norteadas por preceitos exclusivamente capitalistas. / [en] This thesis conducts a critical analysis of Getty Images to understand updates to surveillance and control procedures carried out in the field of advertising. It starts from the media archeology in search of specificities of the audiovisual database to understand protocols proper to the virtual environment that are often organized based on the logic of invisibility. Through the semiotic analysis of five advertising films produced for the brand by the Brazilian advertising agency, AlmapBBDO, it is possible to identify in more depth strategies for communicating Getty Images values and principles. In line with montage techniques, dialogue with fragmented language and from the re-appropriation of audiovisual content, small video-essays are produced that aim to revisit and explore paradigms of the image, as well as contribute to the reflection of the latent potential of audiovisual databases. Concomitantly, the prospect of creative construction of monsters is presented as an increasingly recurring advertising strategy as a stage of audiovisual production. Also, an approach is developed between cinematographic and advertising techniques that seeks to underline hybridism and possible interconnections between the two areas. Finally, examples are presented that point to potential uses of advertising as a form of resistance and to promote critical reflection in front of circumstances exclusively guided by capitalist precepts.
