In den vergangenen Jahren widmete sich eine stetig steigende Anzahl von Ausstellungen und Reenactments der Vergegenwärtigung und Re-Vision der Geschichte von Performance-Kunst und integrierte Aufführungen in diesen Kontext. Sie sind beweglicher Umgang mit den Performance-Archiven. Sie aktualisieren die Frage nach dem Charakter der Artefakte, auf die sich alte und neue Erzählungen zu und über Geschichte(n) der Performance beziehen und thematisieren ihre Lesbarkeit in je neuen Zusammenhängen. Wie in der Bewegungsspur, die den Zuschauern angeboten wird, Zugänge eröffnet werden, wird anhand von Ausstellungsbeispielen untersucht.

This essay explores the sublime aspects in Edgar Allan Poe’s fictional horror, namely "The Tell-Tale Heart" (1843), "The Fall of the House of Usher" (1839) and "The Raven" (1839). The aim is to show that the sublime – an aesthetic experience articulated by Edmund Burke and Immanuel Kant amongst many – can make the reader oscillate between horror and safety. This essay also examines Poe’s works through the lens of Sigmund Freud’s concept of the uncanny to provide a contrasting, more nuanced analysis and understanding. The evidence presented in the analysis shows that Poe’s masterful use of writing techniques, including literary devices such as irony, demonstrates his unparalleled ability to simultaneously terrify and amaze his readers – the core idea of the sublime. Above all, the narrators in Poe’s works play a critical role in conveying the experience of the sublime, as their transgressive actions provide a lens through which the reader can experience both horror, wonder, and incomprehension. Poe’s works involve conflicts between imagination and reason, and rationality and irrationality, as well as the narrow border between the unfamiliar and the familiar – all concepts that tend to evoke both horror and awe. All combined, they have the power to evoke a feeling of the sublime – a concept that could undermine horror and thus make it more pleasurable to read.

This essay is a contribution to literary history that explores Edgar Allan Poe’s criticism of the transcendentalist movement and its key figure Ralph Waldo Emerson through an analysis of the short stories “The Fall of the House of Usher” and “Never Bet the Devil Your Head.” By using genre criticism to define aspects of the Gothic genre, Poe’s criticism through Gothic tropes is studied together with an intertextual reading of the short stories and historical literary objects such as letters, magazines and literary reviews that details his views on transcendentalism. The purpose of this is to see if Poe used his fictional work to criticize his contemporaries. The analysis finds that “Never Bet the Devil Your Head” includes satirical comments on transcendentalist beliefs, as well one instance of specific criticism that targets Ralph Waldo Emerson as a writer - all of which can be connected to Poe’s non-fictional correspondence with fellow literati. In “The Fall of the House of Usher” Poe utilizes aspects of the Gothic genre that function as opposites to common transcendental beliefs.

During the Apollo 10 and 17 missions NASA astronauts reported that they saw streamers emanating from the surface of the moon. They concluded that the streamers were produced by light scattering from dust particles. The particles are believed to be transported by an ambient electric field. This theorized electric field has never been measured directly, although the electric potential on the surface and above it has. The exact behavior and origin of the electric field is unknown, but has been approximated to be between 1 and 12 V/m. To measure this electrical field a new type of instrument, called Multi Plate Field Mills (MPFM) has been developed. This type of instrument is capable of measuring both the amplitude and directionality of the electrical field. Three of these instruments will be mounted on a 1U CubeSat to be lunched with the PTS mission to the moon scheduled to Q4 2019. In this work the MPFM were characterized. The precision of the instrument for electrical fields applied along the z, y and x axis was found to be 0.6, 1.3, 1.4 (V/m)/(Hz)^(1/2) respectively for measurements in air and 0.14, 0.6, 0.6 (V/m)/(Hz)^(1/2) for measurements in vacuum. This sensitivity outperforms the current state of the art Field Mills and, in addition to that, it provides an assessment of the directionality of the electrical field. / Umeå Lunar Venture

Interpretations of the Politics of Fictive Landscapes in Context: A Comparison of Allan Sekula's Sketch on a Geography Lesson and Martha Rosler's In the Place of the Public Airport Series Throughout this thesis project I examine the geopolitical context(s) of the photographs featured in Martha Rosler's 'In the Place of the Public Airport Series' (1983) and Allan Sekula's series, 'Sketch on a Geography Lesson' (1982). I investigate the manner in which they question the legitimacy of the genre of documentary photography within the post-modern age by emphasizing the documentation of an actual physical place, presenting an alternative to the post-modern notion of photograph merely as another component of simulacra, or the intentional creation of an image without meaning or origin. By looking at photographs that Rosler and Sekula made during the burgeoning stages of post-modern theory, presents a broader interpretation of the development of Marxist documentary photography from the early 1980's to today. One way in which I dialogue with the discourse surrounding documentary photography in the 1980's is to focus on Rosler's and Sekula's intentional choice of material that emphasizes the political dialogue rather than concepts that are abstract and maintain no reference to real life. Furthermore, the period of the 1980's is considered a point in contemporary art history when the political fervor of the 1960's and early 1970's diminished greatly. Departing from this trend, Rosler's and Sekula's work continues to address political ideas throughout the 1980's, creating a bridge to today's photographers, such as Edward Burtynsky and Andreas Gursky who consider aesthetics from a socio-political perspective. / Art History

Ce mémoire analyse les différentes formes d'anglophilie que l'on retrouve chez Stéphane Mallarmé. Edgar Poe est grandement responsable de l'attachement du poète français pour la langue anglaise. En effet, celui-ci affirme dans sa correspondance avoir appris cette langue afin de "mieux lire Poe". Cette étude le mène à devenir professeur d'anglais à Tournon où il connaît en 1866 sa "crise". À ce moment-là, le poète voit sa conception de la poésie se transformer radicalement. Durant la décennie suivante, il entreprend des travaux philologiques ainsi que des traductions. La "décennie anglaise" voit Mallarmé se doter d'outils scientifiques afin de résoudre la crise déclenchée quelques années plus tôt. Cette démarche participe à l'œuvre poétique qu'il produira par la suite puisqu'elle replie le langage sur lui-même, séparant ainsi le signifiant de son référant. L'effacement langagier, qu'il met alors sur pied, permet au poète de préserver l'Idéal du grand Œuvre tout en admettant l'impossibilité de sa réalisation. Notre travail étudie d'abord les textes que Mallarmé consacre à Poe. Le sonnet "Tombeau d'Edgar Poe" écrit en 1877, le texte en prose paru dans Divagations en 1897 et les quelques références qui apparaissent dans les Vers de circonstance, publication posthume, dessinent une image héroïque du poète tout en redéfinissant son rôle. Synthèse des mythes grecs et chrétiens, le poète conçu par Mallarmé lutte avec son verbe contre les effets du temps. Les traductions que Mallarmé fait des poèmes de Poe entre 1862 et 1889 permettent à l'auteur français de manipuler la matière sonore d'une façon nouvelle. Sacrifiant le critère de fidélité au profit de la mélodie, le poète essuiera les reproches de critiques du XIXe et du XXe siècle avant de trouver des appuis chez certains traducteurs de poésie dont Yves Bonnefoy. Les ouvrages philologiques de Mallarmé, quant à eux, étudient la langue anglaise comme une langue étrangère. À partir de ces textes, le poète développera le mythe d'une langue autre qui donnerait accès à un monde jusqu'ici inaccessible. De plus, le travail de réécriture qui se fait dans ces ouvrages annonce la "disparition élocutoire du poète" que nous retrouverons plus tard dans "Crise de ver". Finalement, la lecture que Mallarmé fait de Poe l'aide à concevoir l'Œuvre pure ainsi que l'effacement langagier. En mettant la mort au centre de son œuvre, le poète américain prépare la voie à l'écriture hermétique de Mallarmé.

This dissertation develops and analyzes several techniques for improving channel estimation and tracking performance in distributed multi-input multi-output (D-MIMO) wireless communication systems. D-MIMO communication systems have been studied for the last decade and are known to offer the benefits of antenna arrays, e.g., improved range and data rates, to systems of single-antenna devices. D-MIMO communication systems are considered a promising technology for future wireless standards including advanced cellular communication systems. This dissertation considers problems related to channel estimation and tracking in D-MIMO communication systems and is focused on three related topics: (i) characterizing oscillator stability for nodes in D-MIMO systems, (ii) the development of an optimal unified tracking framework and a performance comparison to previously considered sub-optimal tracking approaches, and (iii) incorporating independent kinematics into dynamic channel models and using accelerometers to improve channel tracking performance. A key challenge of D-MIMO systems is estimating and tracking the time-varying channels present between each pair of nodes in the system. Even if the propagation channel between a pair of nodes is time-invariant, the independent local oscillators in each node cause the carrier phases and frequencies and the effective channels between the nodes to have random time-varying phase offsets. The first part of this dissertation considers the problem of characterizing the stability parameters of the oscillators used as references for the transmitted waveforms. Having good estimates of these parameters is critical to facilitate optimal tracking of the phase and frequency offsets. We develop a new method for estimating these oscillator stability parameters based on Allan deviation measurements and compare this method to several previously developed parameter estimation techniques based on innovation covariance whitening. The Allan deviation method is validated with both simulations and experimental data from low-precision and high-precision oscillators. The second part of this dissertation considers a D-MIMO scenario with $N_t$ transmitters and $N_r$ receivers. While there are $N_t imes N_r$ node-to-node pairwise channels in such a system, there are only $N_t + N_r$ independent oscillators. We develop a new unified tracking model where one Kalman filter jointly tracks all of the pairwise channels and compare the performance of unified tracking to previously developed suboptimal local tracking approaches where the channels are not jointly tracked. Numerical results show that unified tracking tends to provide similar beamforming performance to local tracking but can provide significantly better nullforming performance in some scenarios. The third part of this dissertation considers a scenario where the transmit nodes in a D-MIMO system have independent kinematics. In general, this makes the channel tracking problem more difficult since the independent kinematics make the D-MIMO channels less predictable. We develop dynamics models which incorporate the effects of acceleration on oscillator frequency and displacement on propagation time. The tracking performance of a system with conventional feedback is compared to a system with conventional feedback and local accelerometer measurements. Numerical results show that the tracking performance is significantly improved with local accelerometer measurements.

Valdemar” (1845), “Mesmeric Revelation,” (1844) and “A Tale of the Ragged Mountains” (1844) written by Edgar Allan Poe ( 1809-1849), mainly some related to the mesmerism between 18th and 19th centuries. This thesis contains of an introduction and three chapters. Chapter 1 presents Franz Anton Mesmer (1734-1815) and a therapeutic procedures on mesmerism as well as passes, magnets, wands, baquet, magnetized water, and magnetization of animals, trees, objects are used for treatment of diseases. As well as, the followers of Mesmer, as, A.M.J.C.Puységur (1751-1825), J.P.F.Deleuze (1755-1835), Du Potet (1796-1881). Chapter 2 is based on mesmerism, and trance, induced somnambulism, as methods and experiments adopted by magnetists Charles Poyen (?-1844), John Elliotson (1791-1868), James Esdaile (1808-1859), Robert H. Collyer (1814-1891) that used these resources for surgical procedures, mesmeric analgesia. Chapter 3 presents the author Edgar Allan Poe through of mesmeric tales, in view of dialogues of characters Valdemar and Vankirk have suffered from tuberculosis, and Bedloe is subject to severe bouts of neuralgia, and submitted to mesmeric sleep, by physicians Dr. Templeton Dr. P., Dr. D. e Dr. F. e M. P, e Mr. Theodore L., to meet these practices. Likewise, there were authors have used this therapeutic as, Dumas, Balzac, Victor Hugo, Thomas de Quincey, Elizabeth Barrett Browning, in the sense, scholars such as, Harriet Martineau, Chauncy Hare Townshend. Therefore, final remarks on the mesmeric tales related to the medicine. These short stories display a focus of scientific subjects, as mesmerism, diseases, somnambulism, and passes / Esta tese analisa os contos “O Caso do Sr. Valdemar” (1845), “Revelação Mesmeriana” (1844), e “Uma Estória das Montanhas Ragged” (1844) de Edgar Allan Poe (1809-1849), abordando aspectos do mesmerismo entre os séculos XVIII e XIX. Esta tese é constituída de uma introdução e mais três capítulos. O Capítulo 1 apresenta um contexto acerca da terapêutica do mesmerismo por Franz Anton Mesmer (1734-1815), as técnicas utilizadas, como passes magnetos, varinhas, baquet, água magnetizada para o tratamento de doenças, e a magnetização de animais, árvores e objetos. E os seguidores da sua doutrina, como, A.M.J.C.Puységur (1751-1825), J.P.F.Deleuze (1755-1835), Du Potet (1796-1881). O Capítulo 2 está embasado nos desdobramentos do mesmerismo em função do sonambulismo induzido, analgeisa mesmérica, sendo adotados por alguns magnetizadores da época, como Charles Poyen (?-1844), John Elliotson (1791-1868), James Esdaile (1808-1859), Robert H. Collyer (1814-1891) que empregavam esses recursos para intervenções cirúrgicas. O Capítulo 3 apresenta o autor, Edgar Allan Poe, por meio dos contos mesméricos, tendo em vista os relatos dos personagens Valdemar, Vankirk, que padeciam de tuberculose, e Bedloe, que sofria de nevralgia, sendo submetidos ao estado de transe pelos médicos Templeton, Dr. P., Dr. D., Dr. F., M. P. e Theodore L., que vão ao encontro dessas práticas. Além disso, algumas pessoas influentes que fizeram uso dessa terapêutica, no caso, Dumas, Balzac, Victor Hugo, Thomas de Quincey, Elizabeth Barrett Browning, Harriet Martineau, e Chauncy Hare Townshend. Finalmente, as considerações finais acerca do mesmerismo, e dos contos mesméricos que abordam em face da medicina, as doenças, o sonambulismo, e os passes
