Les premiers comptes rendus de l’histoire du cinéma ont souvent considéré les premiers dessins animés, ou vues de dessins animés, comme des productions différentes des films en prise de vue réelle. Les dessins animés tirent en effet leurs sources d’inspiration d’une gamme relativement différente d’influences, dont les plus importantes sont la lanterne magique, les jouets optiques, la féérie, les récits en images et les comics. Le dessin animé n’en demeure pas moins fondamentalement cinématographique. Les vues de dessins animés de la décennie 1900 ne se distinguent ainsi guère des scènes à trucs sur le plan de la technique et du style. D’abord le fait de pionniers issus de l’illustration comique et du croquis vivant comme Émile Cohl, James Stuart Blackton et Winsor McCay, le dessin animé s’industrialise au cours de la décennie 1910 sous l’impulsion de créateurs venant du monde des comics, dont John Randolph Bray, Earl Hurd, Paul Terry et Max Fleisher. Le processus d’institutionnalisation par lequel le dessin animé en viendra à être considéré comme une catégorie de film à part entière dépend en grande partie de cette industrialisation. Les studios de dessins animés développent des techniques et pratiques managériales spécifiquement dédiées à la production à grande échelle de films d’animation. Le dessin animé se crée ainsi sa propre niche au sein d’une industrie cinématographique dont il dépend toutefois toujours entièrement. Ce phénomène d’individuation repose sur des formules narratives et des personnages récurrents conçus à partir de modèles issus des comics des années 1910. / This dissertation focuses on the institutionalization and industrialization of drawn animation. Animated cartoons are usually seen as being quite different from live action films. They were modelled on traditions found in the realm of magic lantern, opitcal toys, phantasmagoria and comics. Yet, cartoons were fundamentally filmic by nature. Technically and aesthetically, animated films were considered as a category of trick films. In the 1910s, after the pioneering work of Emile Cohl, James Stuart Blackton and Winsor McCay, who were also famous for their work as cartoonists and lightning sketch artists, the nascent industry of animated cartoons recruited talent from the comic strip and the illustration industries, including John Randolph Bray, Earl Hurd, Paul Terry and, later, Max Fleischer. The institutionalization of animated cartoons — that is, the process through which cartoons gained enough visibility so they could be legitimately considered a new category of films — is the result of their industrialization. Animated cartoons studios developed techniques and work management practices that were specific to their needs. While largely dependent on the moving picture industry, animated cartoons created their own niche. This phenomenon of individuation relied heavily on narrative formulas and recurring characters modelled after famous comics of the 1910s.

In this research consumers attitudes towards general food safety and their perceptions of the safety of beef in Japan and Canada are examined. Risk perceptions, the willingness to pay for beef traceability from farm to final consumer and the willingness to pay for animal testing for bovine spongifrom encephalopothy (BSE) are measured through a stated preference exercise, provided as part of national surveys in each country. Japanese respondents continue to have higher risk attitudes and perceptions about beef than Canadian respondents in 2009 as compared to 2006. In each country survey respondents strongly prefer domestic beef over imports from any other country. However, interest in beef from other countries increases as full traceability, or one hundred % animal testing for BSE or both attributes are incorporated into the markets. The willingness to pay increases at a diminishing rate, from either traceability or BSE animal testing to both attributes. In latent class models the Japanese data suggest that there are three distinct classes of survey respondents, where class 1 respondents are characterized as being more trusting and willing to pay for beef from different countries, class 2 respondents strongly prefer domestic beef and their willingness to pay for imported beef does not increase with traceability or animal testing and class 3 respondents would only be willing to pay for traceable and a combination of traceable and animal tested domestic beef. Similarly, Canadian survey respondents can be segregated into two classes. Class 1 consumers are more trusting and will be willing to pay for both domestic and imported beef. Class 2 consumers are more cautious. / Agricultural and Resource Economics

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systems The shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil. In sandy soils, and other fine soils, the ard will at each turn deposit small amounts of roots, soil and debris at the edge of the field, which over the years will build up the walls of the celtic fields. But in boulder-rich soil the ard will constantly have to be lifted and tilted, which means that the material will be released before the ard reaches the edge of the field. Since crops, vegetation, houses, field system areas, etc. are identical or at least similar in both landscape types, they most likely represent the same farming system with hay-meadow – stabling – manure – intensely cultivated fields In most provinces in southern Sweden, the pre-roman celtic fields and clearance cairn areas were replaced by geometrically laid-out strip fields or different kinds of stone-wall complexes enclosing the fields and farms, around AD 200, but not in Småland. There, the clearance cairn areas were used and extended throughout the Iron Age. How can this regional variation be explained? A comparison between the different landscape types reveals no significant differences in tools, crops, houses, etc. that would support that the difference is explained by a shift in farming systems. A more likely hypothesis is that the difference is due to regional pre-state or early-state political structures with an ambition to control land-use. This is based on the observations that 1) within each region the physical appearance of the fossil landscape is very coherent; 2) between the different regions there are significant differences, and; 3) the different systems were introduced approximately simultaneously in the regions Gotland, Öland, Östergötland, Uppland and Västergötland. This hypothesis implies that Småland either had a separate political structure which chose to keep the old clearance cairn land-use system, or lacked a corresponding regional structure.

Ο όγκος των δεδομένων που απαιτούνται για τον έλεγχο της ορθής λειτουργίας ενός συστήματος που υλοποιείται σε ένα ολοκληρωμένο κύκλωμα είναι πάρα πολύ μεγάλος. Αυτό συνεπάγεται ότι ο χρόνος που απαιτείται για τον έλεγχο της ορθής λειτουργίας του ολοκληρωμένου κυκλώματος μπορεί να είναι απαγορευτικά μεγάλος. Για τη μείωση του απαιτούμενου χρόνου χρησιμοποιούνται διάφορες τεχνικές συμπίεσης των δεδομένων δοκιμής. Κάποιες από αυτές τις τεχνικές βασίζονται στην αποστολή κοινών δεδομένων δοκιμής ταυτόχρονα σε περισσότερες από μία μονάδες του ολοκληρωμένου κυκλώματος. Στην εργασία αυτή υλοποιούμε μια από αυτές τις τεχνικές που βασίζεται στην ύπαρξη μονοπατιών ολίσθησης (scan paths) στις μονάδες του ολοκληρωμένου κυκλώματος. Για την περαιτέρω μείωση του χρόνου που απαιτείται για τον έλεγχο της ορθής λειτουργίας του ολοκληρωμένου κυκλώματος γίνεται χρονοπρογραμματισμός της σειράς με την οποία θα ελεγχθεί η ορθή λειτουργία των διαφόρων μονάδων του ολοκληρωμένου κυκλώματος. / The volume of data that is required to test a SoC is too much big. This means that the time that is required for testing can be prohibitorily big. For the reduction of required time are used various techniques of data compaction.Some of these techniques are based on broadcasting the same value to all of the cores on a SoC.In this work we use one of these techniques that are based on the existence of scan chains in the core (broadcast scan).For further reduction of time that is required for testing a circuit we use a core testing schedule algorithm.

Os cilindros do laminador estão posicionados horizontalmente e podem ser operados na velocidade de 0,25 m/s, 0,47 m/s, 0,73 m/s e 1,07 m/s. A velocidade de 0,25 m/s produziu uma tira de melhor qualidade. Ligas hipoeutéticas Pb/Sn (Pb–30%Sn, Pb-40%Sn, Pb-50%Sn) e próxima ao ponto eutético (Pb-63%Sn), respectivamente, com intervalo de solidificação de 75 °C, 56 °C, 31 °C e 6 °C de acordo com o diagrama de fases, foram utilizadas nos ensaios experimentais para obter tiras semi-sólidas fundidas e tixoconformadas para comparação. As diversas simulações usando as ligas de Pb/Sn têm revelado a importância do intervalo de solidificação e temperatura de vazamento da liga, da velocidade dos cilindros, da temperatura do bocal junto ao cilindro inferior, da superfície de acabamento dos cilindros e da geometria da panela intermediária (tundish), sobre a qualidade do produto final. A liga Pb-30%Sn com alto intervalo de solidificação em comparação com outras ligas testadas, apresentou maior dificuldade para ser tixolaminada. Isso ocorreu, porque as ligas de alto intervalo de solidificação tendem a formar trincas à quente no final da solidificação. Como resultado, uma pasta metálica plástica é difícil de formar. O caminho provável para obter uma tira semi-sólida fundida de boa qualidade neste caso, é aplicar uma inoculação que produz grãos finos antes do vazamento. O controle para a tixolaminação empregando a liga Sn-37%Pb com intervalo de solidificação menor, e elevada fluidez, é mais rigoroso para obter uma tira contínua. Conseqüentemente, foram utilizadas diferentes temperaturas de vazamento (260, 240 e 220 ºC) para controlar a fluidez e obter o tempo de contato... / This is an experimental study of cast strip rolling from semi-solid material employing a cooling slope which continuously feeds a rolling mill. The cylinders of the rolling mill are positioned horizontally and can be operated at speeds of 0.25 m/s, 0.47 m/s, 0.73 m/s and 1.07 m/s. The lower speed of 0,25 m/s produces a strip of better quality. Hypoeutectic Pb/Sn alloys (Pb-30%Sn, Pb-40%Sn, Pb-50%Sn) and near eutectic point alloys (Pb-63%Sn), with solidification intervals of 75°C, 56°C, 31°C and 6°C respectively, according to the phase diagram, were used in experimental tests to obtain cast semi-solid and thixorolled strips for comparison. Simulations highlighted the necessary control parameters required to obtain good quality of the strip. These were: control alloy solidification interval, pouring temperature, roll speeds, ceramic nozzle temperature at the lower roll, quality of the roll surface finishing and tundish geometry. The Pb-30%Sn alloy, which has a much higher solidification interval in comparison with the other alloys tested, was difficult to thixoroll. This is because alloys with a high solidification interval tend to form hot tears at the end of solidification, and prevent a plastic metallic mush from forming. The probable solution to obtaining a semi-solid fused strip of good quality with this material, is to apply an inoculation that produces fine grains just before the pouring. In contrast, the parameter control for thixorolling of the Sn-37%Pb alloy, with lesser solidification interval and elevated fluidity, needed to be rigorous to obtain a continuous strip. Consequently, several pouring temperatures (260, 240 and 220ºC) were used to vary the fluidity and obtain sufficient alloy-inferior cylinder contact time for complete solidification. The strips obtained by the twin and single roll processing, and conventional rolling were characterized... (Complete abstract click electronic access below)

Twentieth century American fiction assimilates archetypes of traditional mythologies, in particular the hero archetype, to create a contemporary mythology which relays social issues relevant to its age. This is first approached by creating a theoretical framework, which primarily consists of both Jungian theories of the collective unconscious and the model on which Joseph Campbell based his conception of the archetype in what is known as myth criticism. The theoretical framework also introduces and describes the graphic novel and its use of characterisation distinctive to post-modern fiction. The Sandman, which is the subject of this study, is then contextualised against the backdrop of the evolution of the American comic book, with its influence of folklore, mythology and visual presentation. Through an overview and analysis of The Sandman series as a whole, as well as a reading of its pivotal narrative, The Kindly Ones, this thesis explores the way in which The Sandman fulfils its purpose of integrating an archetypal hero into contemporary mythology. This is achieved by validating claims proposing the existence of a contemporary mythology through an analysis of Morpheus, The Sandman's protagonist and his unique heroic journey. The conclusion reached is that The Sandman indeed represents a contemporary mythology that contains a new form of social commentary, incorporating archetypes from traditional mythology and re-evaluating the role of the hero in this day and age. / Afrikaans and Theory of Literature / M.

Title: Measurement of Time-Dependent CP Violation in B0 → ηcK0 S at Belle Experi- ment, Optimization Studies of the Belle II Vertex Detector Author: Zbyněk Drásal Department: Institute of Particle and Nuclear Physics Supervisor: Dr. Zdeněk Doležal, IPNP Supervisor's e-mail address: Zdenek.Dolezal@mff.cuni.cz Abstract: This doctoral thesis deals with two independent topics. In the first part we present a measurement of branching ratio(s) and time-dependent CP violation parame- ters in B0 (B± ) → ηcK0 S(K± ), ηc → p¯p. The values of CP violation parameters have been found as follows: sin 2φ1, denoted as an SCP parameter, equals: SCP = 0.68+0.38 −0.46±0.13syst, the direct CP violation parameter, denoted as an ACP , is: ACP = 0.00+0.23 −0.31 ± 0.08syst. These results have been obtained with the final data sample of 772×106 B ¯B pairs collected at Υ(4S) resonance with a Belle detector at the KEKB e+ e− asymmetric collider machine in Japan. In the second part, we present our approach to the Monte Carlo (MC) simula- tion of Belle II vertex detector and its response to high energy particles. Belle II represents an upgrade of current Belle experiment and its designed vertex detector will consist of 2 layers of Depfet pixel detectors (PXD) and 4 layers of double-sided silicon micro-strip detectors (SVD).

[pt] Após identificar que uma trinca de fadiga permanecia fechada durante parte do ciclo, Elber assumiu que o dano era induzido apenas pela fração do carregamento acima da carga necessária para abrir a trinca. Diversos modelos foram propostos utilizando o Delta Keff como força motriz da propagação, como os modelos da faixa plástica (strip-yield), que são amplamente utilizados para prever vida residual de componentes trincados. Embora o fenômeno do fechamento da trinca esteja provado, sua real importância na propagação da trinca de fadiga ainda é controversa. Outros mecanismos, além do fechamento da trinca, foram utilizados na tentativa de explicar os efeitos de sequência do carregamento na propagação em amplitude variável como o campo de tensão residual à frente da trinca. Mesmo após mais de 50 anos de pesquisas desde a proposição da primeira regra de propagação por Paris ainda não há consenso nem sobre o mecanismo nem sobre a modelagem. Esse trabalho tem como objetivo apresentar uma modelagem para prever propagação da trinca de fadiga com base na hipótese de que o dano acumulado por deformação plástica seria a força motriz para propagação. A modelagem proposta se diferença de outros modelos de acúmulo de dano por permitir que o contato existente entre as superfícies da trinca exerça influência sobre as deformações plástica à frente de sua ponta. Os resultados mostram que a modelagem proposta possui capacidade de reproduzir curvas de propagação semelhante ao modelo strip-yield. / [en] After identify that a fatigue crack remains closed during part of the load cycle, Elber assumed the damage was induced only by the cycle part over the load required to open the crack. Several models were developed based on Delta Keff as the strip-yield ones, which are widely used to predict residual lives of cracked components. Although the crack closure phenomenon is well proven its actual significance for the propagation is still controversial. Others mechanisms, beyond the crack closure, were used in trying to explain the sequence effects on variable amplitude crack propagation like the residual stress field ahead of the crack tip. However even after more than 50 years of research since the first propagation rule proposed by Paris there is no neither about the mechanism neither about modelling. This work has the aim of present a modelling to predict fatigue crack growth based on the hypothesis that the damage accumulated by cyclic plastic strain would be propagation the drive force. The modelling proposed differs from others damage accumulation models by allowing the existed contact between the crack surfaces to exercise its influence on plastic strain ahead of the crack tip. The results show that the proposed model is able to reproduce propagation curves similar to the model strip-yield.

L’Organisation Mondiale de la Santé (OMS) a fixé en 1998 la concentration maximale en arsenic dans l’eau de consommation à 10 ppb (μg/L). Dans le monde, plus de 100 millions de personnes sont exposées à des concentrations supérieures à 50 ppb. La toxicité, l’omniprésence et la mobilité de l’arsenic entraînent la nécessité de pouvoir le doser immédiatement sur le terrain. Il existe actuellement deux méthodes de dosage de terrain commercialisées. La première, onéreuse, est basée sur la voltammétrie (> 7000 €). La seconde à environ 2 €/analyse se présente sous le format de bandelette. Elle permet la mesure de teneurs en arsenic avoisinant les 10 ppb, mais nécessite la génération d’arsine (forme la plus toxique), l’utilisation de bromure de mercure et donne jusqu’à 33% de faux positifs. L’entreprise Novassay souhaite développer une nouvelle méthode de dosage de l’arsenic simple, rapide et efficace pouvant être utilisée directement sur le terrain. Ce travail présente dans un premier temps, un nouveau protocole issu d’une optimisation de la méthode dite au bleu de molybdène et de l’utilisation d’une membrane filtrante permettant une lecture colorimétrique sur support solide. Dans un deuxième temps, seront présentés les résultats obtenus sur le développement d’une méthode de dosage inédite de l’arsenic par l’intermédiaire de nanoparticules d’or. Dans cette partie, une molécule imaginée à partir de la structure d'un complexant naturel de l’arsenic sera synthétisée. Les tests de dosage de l’arsenic avec cette molécule seront réalisés sur deux types de nanoparticules d’or, les premières stabilisées au citrate, les secondes stabilisées au xylane. / In 1998, the World Health Organization (WHO) set the maximum concentration of arsenic in drinking water at 10 ppb (μg/L). In the world, more than 100 million people are exposed to concentrations upper than 50 ppb. The toxicity, ubiquity and mobility of arsenic imply the need to be able to dose it immediately on the field. There are currently two commercially available field dosing methods. The first, expensive, is based on voltammetry (> €7000). The second at about €2/analysis is available in the strip format. It allows the measurement of arsenic concentrations close to 10 ppb but requires the generation of arsine (the most toxic form of arsenic), the use of mercury bromide and gives up to 33% false positives. Novassay wants to develop a new simple, fast and efficient arsenic method that can be used directly in the field. Firstly, this work shows a new protocol resulting from an optimization of the molybdenum blue method and the use of a filtering membrane allowing a colorimetric reading on a solid support. In the second part of this work, the results obtained on the development of a novel method of dosing arsenic by the utilisation of gold nanoparticles will be presented. In this part, an imagined molecule from the structure of a natural complexant of arsenic will be synthesized. The arsenic assay with this molecule will be performed on two types of gold nanoparticles, the first stabilized with citrate, the second stabilized with xylan.
