Lokalizace Verze D textu "Poema Morale" s využitím aplikace "Linguistic Atlas of Early Middle English" / Localisation of Version D of "The Poema Morale" based on "The Linguistic Atlas of Early Middle English"

Vaňková, Marie January 2016 (has links)
The present MA thesis presents an analysis of version D of the Early Middle English verse sermon known as the Poema Morale. The objectives of the study were to verify the present localisation of D in Western Kent and clarify its relations to two more copies of the same text (T and M). The research consistsed in analysing the language of the text it terms of its dialect and distinguishing between different layers of copying, where possible. The analysis was performed using the electronic tool Linguistic Atlas of Early Middle English, specific procedures included mainly analyses of maps showing the distribution of dialectal features found in D, which were complemented by discussions of forms which D shares with other Kentish texts or versions T and M. The aim of these discussions was the identification of words coming from the exemplar. Evidence supporting the localisation of D in Kent as well as forms presumably taken from the archetype were presented and put in the context of the results of previous studies.

Exemplar based texture synthesis : models and applications / Synthèse de texture à partir d’exemples : modèles et applications

Raad cisa, Lara 03 October 2016 (has links)
Cette thèse s’attaque au problème de la synthèse de texture par l’exemple en utilisant des modèles stochastiques locaux de patchs pour générer de nouvelles images. La synthèse de texture par l’exemple a pour but de générer à partir d’un échantillon de texture de nouvelles images qui sont perceptuellement équivalentes à celle de départ. Les méthodes peuvent se regrouper en deux catégories: les méthodes paramétriques et les non paramétriques à base de patchs. Le premier groupe a pour but de caractériser une image de texture à partir d’un ensemble de statistiques qui définissent un processus stochastique sous-jacent. Les résultats visuels de ces méthodes sont satisfaisants, mais seulement pour un groupe réduit de types de texture. La synthèse pour des images de textures ayant des structures très contrastées peut échouer. La deuxième catégorie d’algorithme découpe, puis recolle de manière consistante des voisinages locaux de l’image de départ pour générer de nouvelles configurations plausibles de ces voisinages (ou patchs). Les résultats visuels de ces méthodes sont impressionnants. Néanmoins, on observe souvent des répétitions verbatim de grandes parties de l’image d’entrée qui du coup peuvent être reproduites plusieurs fois. De plus, ces algorithmes peuvent diverger, reproduisant de façon itérative une partie de l’image de l’entrée en négligeant le reste. La première partie de cette thèse présente une approche combinant des idées des deux catégories de méthodes, sous le nom de synthèse localement Gaussienne. On préserve dans cette nouvelle méthode les aspects positifs de chaque approche: la capacité d’innover des méthodes paramétriques, et la capacité de générer des textures fortement structurées des méthodes non paramétriques à base de patchs. Pour ce faire, on construit un modèle Gaussien multidimensionnel des auto-similarités d’une image de texture. Ainsi, on obtient des résultats qui sont visuellement supérieurs à ceux obtenus avec les méthodes paramétriques et qui sont comparables à ceux obtenus avec les méthodes non-paramétriques à base de patchs tout en utilisant une paramétrization locale de l’image. La thèse s’attache aussi à résoudre une autre difficulté des méthodes à base de patchs: le choix de la taille du patch. Afin de réduire significativement cette dépendance, on propose une extension multi échelle de la méthode. Les méthodes à bases de patchs supposent une étape de recollement. En effet, les patchs de l’image synthétisée se superposent entre eux, il faut donc gérer le recollement dans ces zones. La première approche qu’on a considérée consiste à prendre en compte cette contrainte de superposition dans la modélisation des patchs. Les expériences montrent que cela est satisfaisant pour des images de textures périodiques ou pseudo-périodiques et qu’en conséquence l’étape de recollement peut être supprimée pour ces textures. Cependant, pour des images de textures plus complexes ce n’est pas le cas, ce qui nous a menée à suggérer une nouvelle méthode de recollement inspirée du transport optimal. Cette thèse conclut avec une étude complète de l’état de l’art en génération d’images de textures naturelles. L’étude que nous présentons montre que, malgré les progrès considérables des méthodes de synthèse à base d’exemples proposées dans la vaste littérature, et même en les combinant astucieusement, celles-ci sont encore incapables d’émuler des textures complexes et non stationnaires. / This dissertation contributes to the problem of exemplar based texture synthesis by introducing the use of local Gaussian patch models to generate new texture images. Exemplar based texture synthesis is the process of generating, from an input texture sample, new texture images that are perceptually equivalent to the input. There are roughly two main categories of algorithms: the statistics based methods and the non parametric patch based methods. The first one aims to characterize a given texture sample by estimating a set of statistics which will define an underlying stochastic process. The results of this kind of methods are satisfying but only on a small group of textures, failing when important structures are visible in the input provided. The second category methods reorganize local neighborhoods from the input sample in a consistent way creating new texture images. These methods return impressive visual results. Nevertheless, they often yield verbatim copies of large parts of the input sample. Furthermore, they can diverge, starting to reproduce iteratively one part of the input sample and neglecting the rest of it, thus growing ``garbage''. In this thesis we propose a technique combining ideas from the statistic based methods and from the non parametric patch based methods. We call it the locally Gaussian method. The method keeps the positive aspects of both categories: the innovation capacity of the parametric methods and the ability to synthesize highly structured textures of the non parametric methods. To this aim, the self-similarities of a given input texture are modeled with conditional multivariate Gaussian distributions in the patch space. In general, the results that we obtain are visually superior to those obtained with statistic based methods while using local parametric models. On the other hand, our results are comparable to the visual results obtained with the non parametric patch based methods. This dissertation addresses another weakness of all patch based methods. They are strongly dependent on the patch size used, which is decided manually. It is therefore crucial to fix a correct patch size for each synthesis. Since texture images have, in general, details at different scales, we decided to extend the method to a multiscale approach which reduces the strong dependency of the method on the patch size. Patch based methods involve a stitching step. Indeed, the patches used for the synthesis process overlap each other. This overlap must be taken into account to avoid any transition artifact from patch to patch. Our first attempt to deal with it was to consider directly the overlap constraints in the local parametric model. The experiments show that for periodic and pseudo-periodic textures, considering these constraints in the parametrization is enough to avoid the stitching step. Nevertheless, for more complex textures it is not enough, and this led us to suggest a new stitching technique inspired by optimal transport and midway histogram equalization.This thesis ends with an extensive analysis of the generation of several natural textures. This study shows that, in spite of remarkable progress for local textures, the methods proposed in the extensive literature of exemplar based texture synthesis still are incapable of dealing with complex and non-stationary textures.

Mission and hospitality : a literary ethnography of the Pauline Churches

Brouwer, Leendert 11 1900 (has links)
This study explores the practice of hospitality within the Pauline churches and links this practice with mission. It is theoretically informed by Käsemann’s (1963) emphasis on the unity of the church as “an eschatological datum.” While highlighting faith, Käsemann downplays the role of organization and religious practices. Neither he nor missiological studies deal with the practice of hospitality within this context. Hospitality has been interpreted in the literature primarily as an ethic one should adopt towards strangers. Alternatively, this study interprets it as a ritual-like practice aimed at family, friends and strangers in the context of meal gatherings. The question is whether it served as an instrument of koinonia, a practice aimed to create, maintain and extend the Pauline churches as an open network, without denying the role of kerygma. This enquiry utilizes two methodological approaches to answer this question. First of all, it uses Stark’s (1996) network theory of conversion, in order to provide a framework for hospitality in early Christian mission. Secondly, it uses Bell’s (1992) ritual theory in order to interpret meal fellowship in the Pauline churches. Presupposing that science is a conversation, the relationship between missiology and anthropology is depicted as a conversation, ideally an ongoing conversation. This conversation is possible and potentially coherent because the “basic convictions” of both disciplines, respectively love and power, do not contradict each other. The key contribution of this study is that it shows that several practices in the Pauline churches such as welcoming, foot washing, seating order, distribution of portions, etc. qualify as ritual-like. This finding establishes the ritual-like character of meal fellowship within the Pauline churches. Yet, these practices were found ambiguous. They were not simply an instrument to achieve social integration or the transmission of beliefs. While they set the meal off from daily reality, they did not resolve the tension within the churches. Paul knew that this tension was part of a larger apocalyptic picture, the battle between Christ and Satan. Through ritual-like practice he participated in this battle, employing a “poetics of power” that fostered the church as an open network. / Christian Spirituality, Church History and Missiology / D.

Variation phonologique régionale en interaction conversationnelle / Mental representations of regional phonological variation in conversational interaction

Aubanel, Vincent 21 January 2011 (has links)
C'est dans l'interaction sociale, lieu d'occurrence premier du langage parlé (Local, 2003) que la parole est apprise, qu'elle est produite quotidiennement et qu'elle évolue. De nouvelles approches interdisciplinaires de l'étude de la parole, notamment la sociophonétique ou les récents développements de l'interaction conversationnelle, ouvrent de nouvelles perspectives dans la modélisation du traitement de la parole. Une question centrale à cette entreprise est la caractérisation des représentations mentales associées aux sons de la parole. Pour traiter cette question, nous utilisons l'approche exemplariste du traitement de la parole, qui propose que les sons de la parole sont mémorisés en incorporant des informations contextuelles détaillées. Nous présentons une nouvelle tâche interactionnelle, GMUP (pour "Group ’em up"), destinée à recueillir les réalisations de matériel phonologique finement contrôlé produit par deux interactants dans un cadre expérimental écologiquement valide. Les variables phonologiques décrivent les différences existant entre deux variétés de français parlé, le français standard et le français méridional. Des outils de reconnaissance automatique de la parole ont été développés pour évaluer la convergence phonétique, observable de l'évolution des représentations mentales, à deux niveaux de granularité : au niveau catégoriel de la variable phonologique et au niveau plus fin, subphonémique. L’emploi de mesures acoustiques détaillées à grande échelle permet de caractériser finement les différences inter-individuelles dans l'évolution de la forme des réalisations acoustiques associées aux représentations mentales en interaction conversationnelle. / It is in social interaction, the primary site of the occurrence of spoken language (Local, 2003) that speech is learned, that it is produced everyday and that it evolves. New interdisciplinary approaches to the study of speech, particularly in sociophonetics and in recent developments in conversational interaction, open new avenues for modeling speech processing. A central question in this enterprise relates to the caracterization of the mental representations of speech sounds. We address this question using the exemplarist approach of speech processing, which proposes that speech sounds are stored in memory along with detailed contextual information. We present a new interactional task, GMUP (which stands for "Group ’em up"), designed to collect realizations of highly-controlled phonological material produced by two interactants in an ecologically valid experimental setting. The phonological variables describe differences between two varieties of spoken French, Northern French and Southern French. Automatic speech recognition tools were developed to evaluate phonetic convergence, an observable of the evolution of the mental representations of speech, at two levels of granularity: at the categorical level of the phonological variable and at a more fine-grained, subphonemic level. The use of large-scale detailed acoustic measures allows us to finely caracterize interindividual differences in the evolution of the acoustic realizations associated with the mental representations of speech in conversational interaction.
