Zhang, Xiao. "Restoring dynamic spectra corrupted by radio frequency interference : Application to pulsar observation by SKA-pathfinder low-frequency NenuFAR." Electronic Thesis or Diss., Orléans, 2024. http://www.theses.fr/2024ORLE1027.
Full textPulsars are rapidly rotating neutron stars that emit electromagnetic radiation signals received as periodic pulses, thereby acting as cosmic lighthouses. The excellent stability of these periodic signals makes them invaluable tools for assessing the theory of general relativity and for detecting low frequency gravitational waves. However, their observation by radio telescopes can be made difficult by radio frequency interference (RFI) of various origins. These interferences can alter the pulsar signals, which may significantly complicate the detection and precise extraction of their signatures. This thesis aims to propose deep learning techniques to mitigate the impact of RFI in pulsar observations. In particular, this thesis illustrates the interest of these methods in the case of observations carried out by NenuFAR, a pathfinder for the low-frequency segment of the upcoming Square Kilometre Array (SKA).The first part of this thesis begins presenting the astrophysical background of pulsars, emphasizing their importance and role in contemporary astronomy. It then introduces the NenuFAR radio telescope, detailing its technical specifications, observational capabilities, and unique advantages in low-frequency pulsar observations. Lastly, it reviews and summarizes RFI mitigation methods in radio astronomy, analyzing the limitations of existing technologies and identifying the key issues this thesis aims to address. In particular, current RFI mitigation methods often lead to the deletion of data identified as affected by RFI, which inevitably results in a loss of valuable information.In the second part of this thesis, we first present a simulation framework designed to generate RFI-corrupted pulsar observation data. The main goal of this framework is to build a dataset that allows the training of deep learning models, thus circumventing the recurring lack of properly labeled real data.After a thorough review of deep learning and convolutional neural networks, we highlight the shortcomings of existing RFI processing methods, which typically involve identifying and removing data suspected of being corrupted by RFI. To avoid this information loss and address this challenge, we propose a novel approach that consists in formulating the RFI attenuation problem as an image restoration task, aiming at reconstructing RFI-altered signals. Capitalizing on recent advances in deep learning, we show that this task can be efficiently achieved using a network, named RFI-DRUnet, whose architecture is inspired by a high-performance denoising network.In the following chapters, we illustrate the applicability and effectiveness of the proposed approach on simulated and real pulsar observation data, comparing it to current approaches based on deep convolutional neural networks that detect RFI. The results show that the proposed method can effectively restore RFI-corrupted observational signals under various conditions. Furthermore, we discuss the potential impact of this method for improving pulsar chronometry

Full textThis thesis hypothesizes that literary creation, being the ground of a no-structured and undeveloped thought, without any aim to become a generalizing and closed system, allows to put questions and to give several anthropological and cultural interpretations about the human being and the world. Therefore this thesis proposes an analysis of Nancy Huston’s work, novelist of the extreme contemporary, connecting a current feminist perspective on sexual difference with ethical issues and contemporary politics; both referring to the displacement of identity and cultural borders. My work is based on heterogeneous critical sources and reflections: on the one hand the deconstruction post-structuralist notion which lays down the ground for discussions about binary and universalist thought whereas on the other hand stay feminist thinkers inspired by Hanna Arendt’ thought which stresses the value of singularity belonging to a plural community of different beings. Far from reaching a synthesis between these positions Huston’s work appears as an example of articulation of these issues in which both the questioning of sexual difference and poetic relationship are redefined through a practice of thought at work in the literary text

Full textIn this thesis, we have undertaken a stylistic study of metonymy in Emile Zola's following four works : L'Assommoir, Une Page d'Amour, Nana and Pot-Bouille. In so doing, we have selected among the various study fields in stylistics those that allow to examine this figure which is permeating Zola's text. Our aim is to demonstrate that the figure constitutes a prevalence. Moreover, it accounts for the author's ceaseless discursive creativity. The metonymy we have found out throughout these texts shows itself under various typological, grammatical and enunciative forms. Besides, inserted into a literary text, it is the object of considerable pragmatic work on the fictional, thematic and symbolic levels and also on the aesthetic and literary plan. We have realised that a real poetic dimension emanates from the text thanks to the figure called metonymy. First, from the thematic point of view, and thanks to this figure, Zola was able to expose the ridicule of society under the Second Empire. He thus made use of this device in a remarkable way in order to relate literature to science and try to explain the relationship of man with his milieu. Second, thanks to metonymy, a number of lyric and poetic qualities animate the text. If metaphor is the device of imaginary, metonymy is that of “truth and light”, therefore of reality as well as of the imaginary. This characteristic makes metonymy an original trope of the “zolian” text, an actual “novel-poem”

Full textThis research stems from a ten-year experience of Adapted Physical Activities with children and teenagers who were hospitalised in an hemato-oncology ward. This research aims at describing and theorising the impact of ludic adapted physical activities on children, teenagers, the medical staff, and the members of the APA team. The unconscious aspects of the relationships between these intervenants have been studied, where individuals responded in their own way to the difficult time they had to go through. The research emphasises the importance, complexity and particularity of the pedagogical and human relationships - all the more because the APA are proposed to patients whose body also showed signs of suffering from a lethal disease. I attempted to define the nature of the necessary transference between the young patient and the person who engaged him in practising the APA. This was achieved in a constant to and fro between on-the-field practice and analysis of psychanalytical theory. The assumption was that it was necessary to analyse the APA sessions and their effects in light of the transference that had emerged between the patient and the APA teacher. The member of the APA team will then use his unconscious knowledge of this one to one relationship to adapt to the patient, and by this broaden and modify his/her theoretical approach to pedagogy and research
Dalles, Maréchal Anne. "Entre chamanisme, broderies et christianismes : (re)création d’identité chez les Nanaïs dans le bassin de l’Amour, Sibérie Extrême-Orientale." Thesis, Université Paris sciences et lettres, 2020. https://tel.archives-ouvertes.fr/tel-02870550.
Full textSituated on both sides of the Russian-Chinese border, the Nanais are one of the populations living in the Amur region. In China, they are called Hezhe. From the Manchu incursion in the northern part of this region, which was followed by the different Russian attempts at colonization, the Nanais have adapted their way of life, culture and religion as the Amur went through economic, geopolitical and social changes. On both sides of the frontier, as a political and research topic, undergoing russification since the second half of the 19th century, and sinicization before that, the fragmented cultural “identity” of the Nanais is the reflection of these different issues. In this PhD thesis in anthropology, I endeavor to analyze the different modes of expression of « identity » used by the Nanais or the Hezhe to study how disruptions or continuities brought by the region’s recent history to a culture considered as traditional are addressed. In Russia, until the 1970s, according to the Nanai religious shamanistic system, the souls of the living and of the dead were dealt with by a shaman and by complex sets of rituals. Following the end of the soviet regime, since the end of the 1990s, the shamans have disappeared. As a result of their disappearance, to the russification of the way of life and to the arrival of orthodox and protestant missionaries, the Nanai religious practices have become plural. This can be seen in the ritual adaptations made to compensate the shamans’ absence, in the cultural elements considered as essentially “Nanai”, and in the conversions to different forms of Christianity. The question of the perception – be it emic or not – of the Nanai “identity” can therefore be raised. This thesis is divided into three parts. The first one focusses on the transformations brought to the funerary practices and their limits, seen in the presence of harmful souls and spirits. The second one deals with the role of embroideries in the conception of a visible Nanai or Hezhe “identity,” staged for the “safeguarding” of practices considered as native. The third one centers on the conversions to Christian movements established in the region, to show two possible ways of becoming Christian, fluctuating between historical continuity and systemic disruption. The religious and cultural interactions give rise to different forms of indigenous appropriations which ensure the continuity of the shamanistic representations. The transformation of these practices also leads to the emic perception of a « loss » of culture. The question of the perception of disruptions or continuities regarding a culture considered as traditional lies in the analysis of these plural practices. The study of these different aspects enables my analysis to be centered on three main themes: 1) the analysis of the dealing with the spirits and the souls highlights the historical continuity of Nanai shamanistic representations while also underlining the emic perception of the “loss” of culture considered as traditional; 2) the identification of practices considered as essentially “Nanai”, “Hezhe” and/or “traditional” raises the question of what it means to “be Nanai” today (for the Nanais themselves and for the non-Nanais); 3) the adaptation of shamanistic practices and the adoption of new ones show an ambivalent and changing position concerning the desire to break with shamanistic representations or to maintain some of their features. In the study of the funerary adaptations, of cultural demonstrations and of conversions to different forms of Christianity, these three themes show that the plurality of practices actually convey different modes of expressions of the contemporary Nanai “identity”

The traditional folk arts in Taiwan have undergone political and economic transitions; as a result, traditional temple activity Din Tao is facing the crisis of inheritance. This study investigated the historical changes of Chen-Shin-She Martial Arts Club, as well as the formation and layout culture, inheritance, and prospect of Lion Dance. The author performed a comprehensive document analysis, conducted in-depth field interviews, and participated in the Nanyao Temple Er-Ma-Wu on-foot pilgrimage in 2017. The author observed and documented the 7-day and 6-night trip (from March 12, 2017 to March 18, 2017), and reached the following conclusions: 1. Historical changes This study clarified the dependence relationship. Chen-Shin-She Martial Arts Club formally became the guardian team for Matsu’s sedan of Changhua Nanyao Temple in 1946 to ensure the safety of incense holders and worshippers. 2. Formation and layout culture of Lion Dance Although the movements of rituals, “khi - bé,” “chiap - bé,” and “lok - bé” are the same, their meanings are different. The meaning of “khi - bé” ritual is to inform ancestors and gods in the temple and pray for successful performance of Lion Dance and safe return of members. The meaning of “chiap - bé” is to represent the temple to welcome the Lion Dance performers. The meaning of “lok - bé” is to inform ancestors and gods in the temple and pray for successful performance of Lion Dance and safe return of all of the members in the guardian team. Keywords: Lion Dance, formation and layout, Chen-Shin-She Martial Arts Club
Breton, Mahité. "Hic et Nunc : forces et limites de l'esprit chez Ivan Illich." Thèse, 2015. http://hdl.handle.net/1866/18449.
Full textThis thesis explores the foundations of Ivan Illich’s thinking and its implications for language and for our ways of relating to one another. His thinking is rooted in a singular vision of the human being as a creature who achieves perfection by establishing a relationship that is free and fully incarnate. I explore this fundamental idea through three major lines of thought running through Illich’s oeuvre : relations between self and other; the role of institutions; the practice of language. In the first chapter I examine this vision through Illich’s way of thinking together with friends, a convivially practiced search for truth. He thus places himself in the filiation of the Good Samaritan from the parable of the Gospels. In Illich’s highly personal interpretation, which stands outside the mainstream Christian tradition, this parable bears on the relationship between faith and reason. In Illich’s view, Jesus reveals that no rule dictates who is my neighbor: the Samaritan’s gesture of charity toward the Jew is completely gratuitous and comes from a deeply felt unease (Illich refers to the Hebrew word rhacham, often translated as mercy). In the second chapter I discuss the worldview that results from such an interpretation. For Illich, the Gospels open up a unique opportunity to be with each other beyond the rules that frame various groups (clan, tribe, nation etc). This thinking leads him to perceive the institutions and organizations of Western society as resulting from a perversion of that opportunity, because they seek to guarantee—through a structure or a service—precisely what should remain a freely-chosen, personal inclination. Illich demonstrates that by renouncing any guarantee and power in the world, we can still be with each other and live up to our personal inclination as creatures. Jean-Luc Nancy’s thinking on being-one-with-another offers here a counterpoint to Illich’s intuition and shows how this intuition goes beyond the Christian tradition by fully adhering to the human condition. Finally, in the third chapter, I approach language as the intangible reverse side of the irreducible condition of being with one another. According to Illich, the language we speak has also been corrupted through institutionalization. He traces the origin of this corruption to the Middle Ages, with the emergence of the notion of "mother tongue" and of its transmission via teaching. Through both his practice and his writing, however, Illich shows that uncorrupted speech remains possible, when punctuated by the silence of asceticism and listening. The iv words of Paul Celan on the persistence of speech in a corrupt world relays and responds to Illich’s thoughts on this theme, thus opening a rich dialogue on the possibility—always present, but never guaranteed—to speak with one another. Interwoven throughout these themes is the temporal dimension of hic et nunc, the here and now between us, which constantly surfaces in Illich’s writings yet remains difficult to grasp with the human mind.
