The U.S. Navy currently has no means to conduct sea mine reconnaissance with assets that are organic to Aircraft Carrier Battle Groups or Amphibious Ready Groups. Magic Lanten is an Airborne Laser Mine Detection System (ALMDS) under development, that is designed to search for floating and shallow moored mines using a helicopter- mounted laser-optic sensor. It is the only ALMDS operationally tested by the Navy to date. This thesis develops a Monte Carlo simulation model called ML-Recon, which is intended for use as a tool to plan mine reconnaissance searches using the Magic Lantern system. By entering fundamental initial planning information, the user can determine the number of uniformly-spaced tracks to fly with a Magic Lantern-equipped helicopter to achieve a certain level of assurance that the area contains no floating or shallow moored mines. By employing Monte Carlo methods, ML-Recon models the three primary stochastic processes that take place during a typical search: the location of the mines, the cross-track error of the helicopter, and the detection/non-detection process of the sensor. By running ML-Recon, the user is given performance statistics for many replications of the search plan that he chooses. This approach is unique in that it provides the user with information indicating how much worse than the mean performance his plan may perform. ML- Recon also gives the user an Opportunity to view an animation of his lan, which he can use to look for tendencies in the lan to contain holes, or holidays. (AN)

In the early years of the twentieth century, the unique new medium of motion pictures was the focus of significant theorization and experimentation at the fringes of the American advertising industry. Alongside the growth of the nickelodeon, and the multiple shifts in the American cinema's business model in the 'transitional era,' various individuals at the margins of the advertising industry attempted, and most often failed, to integrate direct consumer-goods advertising regularly into motion picture theaters. Via techniques as diverse as the glass slide, the commercial trailer, and the advertising wall-clock, cinema patrons of the 1910s witnessed various attempts by merchants and manufacturers to intrude upon their attention in the cinema space. Through research in the trade presses of the cinema, advertising, and various consumer-goods industries, along with archival ephemera from the advertising companies themselves, this dissertation explores these various on and off-screen tactics for direct advertising attempted in silent cinemas, and their eventual minimization in the American cinema experience. Despite the appeal of the new, popular visual medium of cinema to advertisers, concerns over ticket prices, advertising circulation, audience irritation, and the potential for theatrical 'suicide-by-advertising,' resulted, over a mere fifteen years, in the near abandonment of the cinema as an advertising medium. As a transitional medium between the 19th century forms of print and billboarding, and 20th century broadcasting, the silent cinema was an important element in the development of modern advertising theories.

Cette thèse s’inscrit dans le mouvement des études interdisciplinaires portant sur la presse. Son objet est double : la presse de vulgarisation scientifique et les dispositifs optiques. Notre étude débute en 1851, moment de la fondation des premiers titres représentatifs, et s’achève en 1903, période de crise où ces périodiques entament une redéfinition de leurs lignes éditoriales. L’objectif de ce travail est d’étudier la façon dont la presse de vulgarisation scientifique s’empare des dispositifs optiques. Nous montrons que ces dispositifs, mieux que tout autre objet, permettent de comprendre efficacement l’évolution générale de la presse de vulgarisation scientifique dans ses pratiques d’écriture, dans le choix de ses rédacteurs et dans l’évolution des lignes éditoriales. L’étude conjointe de la presse photographique, laquelle se rattache explicitement au mouvement de vulgarisation scientifique, et des périodiques de vulgarisation scientifique généraliste, montre que, si ces deux types de presse cohabitent initialement en s’ignorant largement, ils finissent par se rencontrer et s’influencer mutuellement. Cette thèse visant à offrir une cartographie détaillée des périodiques et du personnel qui y officie, elle s’accompagne d’annexes incluant un répertoire des périodiques traités, ainsi qu’un premier répertoire des personnalités de la vulgarisation scientifique et une chronologie
This dissertation is part of interdisciplinary studies dealing with the press. Its subject-matter is twofold: french popular science newspapers and optical devices. Our study begins in 1851 with the founding of the first popular science magazines, and ends in 1903, year of crisis during which this periodical press begins to redefine its editorial lines.The purpose of this work is to study how the popular science press got hold of optical devices. We show that these devices, better than any other object, allow effectively to understand the general development of the popular science press in its writing practices, in the choice of its writers, and in the evolution of its editorial lines. The joint study of photographic newspapers, which are explicitly linked to the popular science movement, and general popular scientific journals, shows that both types of press initially ignore each other, but eventually meet and influence each other.This dissertation aims at providing a detailed description of this periodical press and its staff: it is accompanied by appendices including a detailed index of those newspapers, and another detailed index of popular science writers. It also includes a chronology

The late nineteenth century and early twentieth century were an important period for popular shows involving the moving and projected image, yet there have been few sustained studies that have mapped optical entertainments systematically outside London or that have analysed the influence of such shows on early film exhibition. This thesis has profiled the popular and visual culture of five contrasting South West locations during this period, tracing the development and distribution of magic lantern shows and dioramas as well as identifying the local and touring companies who hosted film on its arrival in the region. Using the local press, the trade press, contemporary publications and ephemera, this thesis has reconstructed an account of local shows and culture which not only deepens our understanding of popular visual entertainments in regional contexts, but which also serves to stand as a comparison to other established urban and metropolitan paradigms and thus to contribute to a wider and more complex national picture. It advances the argument for a broader classification of such shows in response to local findings and for a more nuanced and detailed appraisal and understanding of their provenance and profiles, and the role film played within them. In addition, this thesis interrogates early film exhibition in these resorts following the move to fixed-venue cinemas in the late 1900s and investigates the arrival of cinema and its emergence as a fledgling industry in the region. It offers an overview of investment into the business locally and evidences the varied set of partnerships and individuals responsible for financing the first cinemas here. Responses to the new technologies and local modifications to business models for cinemas and film exhibition are analysed and their diversity examined. Managerial relationships with communities are evidenced as an important contributory factor to the success of many local cinemas, permitting adaptations to the needs of patrons which boosted audiences and increased revenue. The variety of local interpretations of cinema discovered here reflects the social and cultural diversity of these selected sites, and is a key finding of this thesis.

This thesis is about the mobilities of geographical knowledge in the material form of lantern-slides and the forces exerted on these by technological and human factors. Owing to its concern with matter, human- and non-human, and its circulation, the thesis addresses the physics of geographical knowledge. The chapters below investigate the Royal Geographical Society’s (RGS) ongoing tradition of telling stories of science and exploration through words, objects and pictures in the final quarter of the nineteenth century and as geography professionalized and geographical science developed. These processes occurred within the context of a plethora of technological innovations, including the combination of the older medium of the magic lantern and photographic lantern-slides, integral to a wide range of entertainment, scientific and educational performances across Britain. In 1886 the RGS began to engage with the magic lantern. Via this technology and the interactive lecture performances in which it featured, I argue that the Society embraced the medium of photography, thereby engendering transformations in methods of knowledge making and to the RGS collections. I study how these transformations influenced the discipline of Geography as it was re-established at the University of Oxford in 1887. I demonstrate the evolution of the RGS’s Evening, Technical and Young Persons’ lectures, their contingent lantern-slide practices and, consequently, how these moulded, and were moulded by, the RGS Fellowship between c. 1885 and 1924. The chapters below explore how these innovations in visual technologies and practices arose, how they circulated knowledge and their effect on geographies of geographical knowledge making. By harnessing the lantern the RGS attracted an expanding and diversifying audience demographic. The thesis demonstrates the interactive nature of RGS lantern-slide lectures and audiences' important role in shaping the Society’s practices and geographical knowledge. The chapters below argue that it was via the use of the lantern that geography was disseminated to new places. The thesis therefore brings additional perspectives and dimensions to understandings of the circulation of geographical knowledge.

A fortuna crítica de À la recherche du temps perdu sempre teve como um dos seus principais motes a relação da obra com outras artes, ou seja, uma construção estética baseada em uma relação de homologia estrutural com outros sistemas artísticos, dentre eles a música, a arquitetura, a própria literatura e a pintura. Essa construção faz com que a obra venha constantemente acompanhada do epíteto de museu imaginário. Especificamente, o nome do pintor holandês Johannes Ver Meer tem um lugar privilegiado na estética proustiana. Entretanto, nem todas as telas são mencionadas ao longo da narrativa. Somada a isso, a tessitura da escritura de Marcel Proust revela-se como um saber fortemente indiciário. Assim, a partir de índices que percorrem epístolas de Proust, textos críticos e a própria narrativa de À la recherche du temps perdu, esta tese cujo recorte de leitura é especificamente o episódio da lanterna mágica e seus desdobramentos defende que uma das telas de Ver Meer, a saber, A arte da pintura, é uma ausência epistêmica que, no entanto, faz-se presente, deixando inscritos na obra seus efeitos de significação. A fim de compreendermos essa presença-ausente, esta tese recorre ao conceito de letra, conforme o ensino de Jacques Lacan, os textos freudianos nos quais esse conceito estava em latência e os esclarecimentos e avanços feitos por Jacques Derrida, especificamente em seus textos da década de sessenta do século passado. Por efeitos de significação, concebe-se a ideia de que A arte da pintura realiza-se como uma ideia ausente, mas pungente no que tange aos efeitos estéticos de esmero do detalhe e dos processos descritivos, implicando uma relação de similitude entre o narrador em seu quarto, em lincipit de À la recherche du temps perdu e no episódio da lanterna mágica, e um artista em seu ateliê, presente na tela de Ver Meer, que incidirá em uma poética do detalhe.
The critical fortune of À la Recherche du Temps Perdu has always had, as one of its main threads, the relationship of work with other art forms, in other words, an aesthetic construction based on a relationship of structural homology with other Arts, including music, architecture, literature itself and painting. This ensures that the work is constantly accompanied by the epithet of the imaginary museum. Specifically, the name of the Dutch painter Johannes Ver Meer has a privileged place in the Proustian aesthetic. Nevertheless, not all canvases are mentioned during the narrative. Added to this, the tone of the Marcel Proust text reveals itself as a clear, evidentiary wisdom. Therefore, from indices that permeate the Proust missives, critical texts and the narrative of À la Recherche du Temps Perdu, this thesis, the scope of which is limited specifically to the episode of the Magic Lantern and its ramifications, argues that one of Ver Meers canvases, namely that of the Art of Painting, is epistemically absent, however it makes its presence felt through its effects of significance on the piece. In order to understand this absent-presence, this thesis uses the concept of the letter, according to the teachings of Jacques Lacan, Freudian texts in which this concept was latent, and in the clarifications and advances made by Jacques Derrida in his writings of the 1960s. For purpose of meaning, one has conceived the idea that The Art of Painting be like a missing yet poignant idea touching the aesthetic effects of minute detail and of the descriptive processes, implying an affinity in relationship between the narrator in his chamber, in l\'incipit of la Recherche du Temps Perdu and the episode of the Magic Lantern, and the artist in his studio, present on Ver Meers canvas, reflected in a poetic detail.

La lumière représente un thème récurrent dans A la recherche du temps perdu – on note en particulier l’importance de la lanterne magique dès l’ouverture du roman ; elle sert fréquemment de métaphore à la création artistique : aussi ai-je choisi d’étudier ce motif tant du point de vue des manifestations de la lumière elle-même que de celui de sa dimension symbolique dans l’œuvre, m’appuyant sur des analyses lexicologiques et stylistiques. Je travaille dans un premier temps sur les mots de la lumière créatrice qui regroupent le substantif lumière lui-même dont je propose une analyse sémasiologique, ainsi que certains de ses parasynonymes (entre autres : soleil, lune, jour, clarté, lueur, éclairage, ombre, reflet, rayon…) par une recherche de paradigmes de substitution dans l’œuvre. Puis, dans un deuxième temps, j’observe si dans leur structure même les phrases de Proust intègrent des propriétés de la lumière (phrases trajectoires à l’instar d’un rayon lumineux ; phrases transvertébration ; phrases vitraux), puisque les notions d’optique et de fragmentation apparaissent essentielles dans la vision du monde de l’auteur. Je dégage enfin des figures (métaphore, syllepse et antanaclase dans leur rôle stylistique, ainsi que certains fonctionnements de la coordination et) que j’analyse plus spécialement dans la mesure où elles réalisent dans un cadre plus large que celui de la phrase des caractéristiques de la lumière ; on découvre alors que l’art photographique et ses techniques peuvent éclairer de façon métaphorique l’art de Proust, l’auteur de La Recherche en appelant de façon de plus en plus insistante au cours du roman à l’image du développement photographique
Light is a recurring theme throughout Remembrance of Things Past - the magic lantern's importance is to be noted from the novel's beginning. Light is often used as a metaphor for artistic creation. Thus, I have chosen to study this motif focusing on light-induced patterns as well as how it becomes symbolic in the context of the novel. I will use lexicological and stylistic analysis to do so.I have first worked on words connected to creative light for which I will propose a semiasiological analysis including of the substantive light itself. I have also focused on some its para synonymous terms such as sun, moon, day, brightness, glow, lighting, shade, glint, beam...by looking for paradigms used instead in the novel.Secondly, I have examined whether some of light's properties – path sentences like rays of light ; transvertebration, stained glass window sentences - are part of the structure of Proust's sentences, since focus and fragmentation structure the author' insight into his world.Finally, I have selected literary devices - metaphors, syllepses and antanaclases in their stylistic function as well as some uses of the coordination conjunction and – and analysed them in so far as they convey the characteristics of light beyond the structure of sentences. The art of photography and its techniques are then shown metaphorically shedding light and interplaying with the art of Proust, the author of Remembrance of Things Past, progressively conjuring the image of photographice development process

The present work arises as part of the first systematic investigation on hand-painted magic lantern glass slides resorting to multi-analytical techniques combined with critical analysis of historical written sources on the painting materials and techniques used to produce them. The magic lantern was an optical instrument, used to project images from the seventeenth to the twentieth centuries, that attained great success with high impact on entertainment, science, religion and advertisement. In the framework of this work, five hand-painted magic lantern glass slides from the National Museum of Natural History and Science (University of Lisbon) were studied. The glass support, the colourants and organic media were characterised. The glass was analysed by Micro-Energy Dispersive X-Ray Fluorescence, and the oxide quantification unveiled that the glass belongs to the soda-lime silicate type and was possibly produced between 1870 and 1930 in England. Additionally, considering the standardized size of the slides and the similarity of the subjects represented with other English slides from the nineteenth century, it was possible to narrow the production period of this collection between 1870 and 1900. Ultraviolet-Visible, Micro-Raman and Micro-Fourier Transform Infrared spectroscopies allowed the characterisation of the colourants. The colour palette is composed of Prussian blue, an anthraquinone red lake pigment of animal origin (such as cochineal carmine), an organic yellow whose identification was not yet possible and a carbon-based black pigment. The remaining colours – green, purple and brown – were achieved by mixing the pure pigments. Through infrared analysis, a terpenoid resin such as shellac was identified. The detection of metal carboxylates was essential to assess the state of conservation of the paints. The identification of the main risks that might endanger the collection in study was made, as well as a risk assessment scale. Preventive conservation guidelines were proposed taking into consideration the literature on the preservation of the different materials that compose the magic lantern slides, as well as the results of surveys submitted to national and international museums that hold similar collections.
