Maurice Maeterlinck, an author in the cinema of the 1910s and the 1920s: history, sociology and aesthetic
No full textSi l’œuvre littéraire de Maurice Maeterlinck suscite nombre de recherches, ses activités dans le domaine du cinéma sont moins connues et moins étudiées. La présente thèse, qui s’appuie sur les concepts de la sociologie de Pierre Bourdieu, entend combler une lacune en analysant la trajectoire de l’auteur dans le champ cinématographique pendant les années 1910 et 1920, c’est-à-dire la période où il manifeste le plus d’intérêt pour le cinéma. L’étude comprend trois analyses. La première concerne le point de vue de Maurice Maeterlinck, son entrée et son déplacement dans le champ cinématographique. L’auteur consacré dans son champ d’origine développe, dans le nouveau champ investi, des produits dérivés orientés vers le public élargi et diversifié. La deuxième analyse concerne les transformations du champ cinématographique et le point de vue des autres agents, en particulier celui des maisons de production et de distribution. Celles-ci insèrent les adaptations de l’auteur dans une série de produits plus ou moins standardisés, qui leur permettent de se situer dans le champ. La troisième analyse concerne quelques films et projets de films datant des années 1910 et 1920, liés aux œuvres littéraires de Maurice Maeterlinck, comme The Blue Bird (Maurice Tourneur, 1918). Aussi bien les composantes externes (par exemple, la mise en place du projet, la production ou l’exploitation) que les composantes internes (par exemple, la mise en scène ou l’éclairage) sont les indicateurs de la position de l’auteur et les indicateurs du fonctionnement du champ dans son ensemble. / The researches on the literary works of Maurice Maeterlinck are numerous but his activity in the cinema is less known and less studied. The PhD thesis is based on the concepts of the sociology of Pierre Bourdieu ;its purpose is to bring new information by analyzing the trajectory of the author in the cinematic field during the 1910s and the 1920s, when he is the most interested in the cinema. The study includes three analyses. The first one concerns Maurice Maeterlinck's point of view, his entrance and his movement in the cinematic field. The author who is recognized in his first field develops in the new invested field several products who are directed to the widened and diversified public. The second analysis concerns the transformations of the cinematic field and the point of view of the other agents, e.g. the houses of production and distribution. These houses insert the adaptations of the author into a series of more or less standardized products, which allow them to be situated in the field. The third analysis concerns some films and projects of films of the 1910s and the 1920s, adapted from the literary works of Maurice Maeterlinck (e.g. The Blue Bird, Maurice Tourneur, 1918). The external components (the organization of the project, the production or the exploitation) and the internal components (the direction or the lighting) indicate how the author is situated and how the field is organized.Doctorat en Information et communicationinfo:eu-repo/semantics/nonPublishe

Data from: Population structure of the invasive forest pathogen Hymenoscyphus pseudoalbidus
No full textUnderstanding the genetic diversity and structure of invasive pathogens in source and introduced areas is crucial to reveal hidden biological aspects of an organism, to reconstruct the course of invasions and to establish effective control measures. Hymenoscyphus pseudoalbidus (anamorph: Chalara fraxinea) is an invasive and highly destructive fungal pathogen on common ash Fraxinus excelsior in Europe and occurs natively in east Asia. To get insights into the dispersal mechanism and the history of invasion, we used microsatellite markers and characterized the genetic structure and diversity of H. pseudoalbidus populations at three spatial levels: (i) in Europe; (ii) at the epidemic front and (iii) between Europe and Japan. The 1208 European strains form one large population as no evident structure was detected using Bayesian and multivariate clustering analysis. Only the distribution of genetic diversity in space, pairwise population differentiation (GST) and the spatial analysis of principal components revealed a faint geographic pattern around Europe. A significant allele deficiency in most European populations pointed to a recent genetic bottleneck whereas no pattern of isolation by distance was found. Populations from Japan harbored a higher genetic diversity and were genetically differentiated from European ones. Nevertheless, phylogenetic and network analysis clearly demonstrated that individuals from both regions are conspecific. Our data suggest that H. pseudoalbidus was introduced only once by a minimum of two individuals. The potential source region of H. pseudoalbidus is huge and further investigations are required for a more accurate localization of the source population
Exploring Gravitational Waves Recordings with Machine Learning Techniques
No full textThe study of Gravitational Waves (GWs) opened a new window of possibilities to improve our understanding of the Universe. GWs provide suitable astronomical messengers for studying events that were not possible before through electromagnetic radiation, or in other cases complementing their observations. Ground-based interferometers like LIGO have been recording multiple GW events since the first detections in 2015. Despite the success of Earth-based observatories, the space limitations and noise sources on Earth point toward the need of building a spaceborne interferometer. The Laser Interferometer Space Antenna (LISA) is a planned project that will provide us with such a detector and will allow gaining access to lower frequency bands and more types of GW sources. To make the most out of LISA’s strengths, it is important to identify and develop alternative data analysis tools which are more appropriate for low latency searches of GWs than the current ones in use. Machine Learning techniques are a promising candidate since they can provide high accuracies, higher speeds, and a lower computational cost. Therefore, they can be used for the development of Low Latency Detectors (LLD) of GWs, which will be used to analyze the LISA recordings. I propose to build a prototype LLD by using a Sliding Window Algorithm, which makes use of Convolutional Neural Networks (CNNs) as its classification mechanism. To implement the LLD, I first create datasets composed of synthetic GW recordings of two different GW source types: Galactic Binaries (GBs) and Merging Blackhole Binaries (MBHBs). Then, I transform these recordings originally represented only in the time domain, into the frequency domain, and the time-frequency domain and train two different ML architectures (CNNs and Fully-Connected Neural Networks) using both the original and the transformed data. A performance evaluation is done to select the best combination of ML architecture and domain representation for solving the detection task. The chosen combination is then used as the classifier mechanism of the LLD acting in windows of five days duration. The LLD is tested on one-year-long recordings with different levels of noise. The analysis suggests that the time-frequency domain representations offer the most promising results for detecting both types of sources (GBs and MBHBs) reaching high accuracies in recordings with low to moderate signal-to-noise ratio (SNR).Applied Geophysics | IDEA Leagu

The cisanthropic figurine - Liminal humanity and affective contagion in animation cinema
No full textThis thesis aims at answering an apparently simple question: How come "cartoony" characters always seem to be able to trigger better affective responses than more realistic ones (therefore avoiding the uncanny valley). By linking classical animated cartoons to their print cartoon ancestors, the author is able to call upon the array of studies on caricature perception to build a new understanding of animated character design, summed up into a type of character called cisanthropic figurine
Digitalisierung in der Schweizer Wirtschaft: Ergebnisse der Umfrage 2016. Eine Teilauswertung im Auftrag des SBFI
No full text[...] Im Dienstleistungssektor ist das Verbreitungsmuster signifikant anders als in der Industrie, erwartungsgemäß insbesondere bei den Produktionstechnologien. Der Baubereich ist beträchtlich weniger digitalisiert als Industrie und Dienstleistungen. Die markantesten Unterschiede bezüglich der Technologieverbreitung scheinen aber größenbedingt zu sein, wobei der technologische Vorsprung der großen Firmen gegenüber den KMU besonders auffallend ist. Die Digitalisierungstechnologien finden breite Verwendung in verschiedenen Unternehmensbereichen. Mit Ausnahme des F&E-Bereichs, der nur für F&E-treibenden Firmen relevant ist, werden die Technologien in allen anderen Bereichen etwa im gleichen Ausmaß eingesetzt. Interessanterweise ist die aufgabenmäßige Beanspruchung von Digitalisierungstechnologien ziemlich ähnlich zwischen Industrie und Dienstleistungssektor. Für Vernetzungszwecke, Automatisierung und Überwachung wird Digitalisierung häufiger bei Industrie- als bei Dienstleistungsfirmen eingesetzt, die Unterschiede sind aber nicht gross. IT-gestützter Austausch von Informationen mit externen Partnern ist häufiger bei Dienstleistungs- als bei Industriefirmen anzutreffen. Verarbeitung von (internen und externen) Informationen wird im gleichen Ausmaß in beiden Sektoren durch Digitalisierung gestützt. Merkliche Unterschiede bestehen zwischen dem Bausektor und den anderen Sektoren. Die Digitalisierung ist im Bausektor bei allen Aufgaben niedriger. [...
