International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Waveform Description Language (WDL) was invented to ease the process of porting legacy and/ or new radio waveforms to Programmable / Software Radios. WDL has two primary requirements; 1st it is to provide a rigorous executable behavioural description of waveform signal structures that is unambiguous and yet independent of any particular end item software radio architecture. The 2nd requirement is that the behavioural specification provides a path to automatic code generation for GP’s, DSP’s, and FPFG’s and that the Generated code be tested against the behavioural model.

Análise e interpretação do conto \"Cara-de-Bronze\", escrito por João Guimarães Rosa. Esta obra sintetiza a idéia que o autor tem da poesia, marcada pela extensa tradição de escritos dedicados ao estudo de Saturno e da melancolia. O confronto dessa tradição, a partir da leitura que lhe deu Walter Benjamin, com o conto, descortina aspectos enigmáticos da narrativa, e revela elementos fundamentais da concepção de mundo do autor, importantes para a literatura, a critica literária e a filosofia da arte. / Analysis and interpretation of the short story \"Cara-de-Bronze\" (\"Bronze Face\"), written by João Guimarães Rosa. This work synthesizes the idea the author has towards poetry, remarked by the long tradition of writings dedicated to the study of Saturn and of melancholy. The confront of such tradition, based on the reading by Walter Benjamin, with the short story, unveils enigmatic aspects of the narrative, and reveals essential elements of the author\'s conception of the world, important for literature, literary criticism and the philosophy of art.

The purpose of this study is to analyze the sedimentology and stratigraphy of the Middle Jurassic Preuss Sandstone and re-evaluate past sedimentological interpretations. The Preuss is located in northern Utah, western Wyoming and eastern Idaho and is stratigraphically equivalent to the Entrada Sandstone, which is Callovian in age (Dossett et al., 2014). This study is the first attempt at 1) a sequence stratigraphic framework, 2) a petroleum system analysis and 3) an extraterrestrial analog study for the Preuss. This study frames the Preuss within three broad facies groups: marine, coastal and terrestrial. The marine group includes the open marine and restricted marine facies with associated subfacies, the coastal group includes coastal sabkha and associated subfacies, and the terrestrial group includes alluvial, inland sabkha and eolian facies with associated subfacies. Three sections in northern Utah and one section in eastern Idaho compromise the focus of this study. The three Utah sections were measured and described, and samples were collected from two Utah sections and the Idaho section. The Preuss Sandstone was deposited in an asymmetrical retroarc basin, consequently the Preuss thickens from the east towards west-central Utah and the Jurassic Elko highlands. The deposits are mostly terrestrial, which is in accord with recent sedimentological interpretations, but at odds with the old paradigm, which postulates that the Entrada and Preuss were largely tidal in origin. There are marine transgressions within the trough of the retroarc basin, and the transgressions affect terrestrial sedimentary patterns. During marine incurstions, alluvium shed off the highlands is confined west of the seaway, and does not prograde east of the trough until all the available accommodation is filled. The Preuss was deposited during a complete third-order sequence-stratigraphic cycle that lies within the Lower Zuni II second-order lowstand. The Preuss Sandstone can be used as an outcrop analog for ancient and modern environments both here on Earth and on other planetary bodies. The petroliferous Norphlet Formation along the U.S. Gulf Coast was deposited in an environment very similar to the Preuss, but the Waltherian succession of facies might be slightly different. Likewise, the facies present in the Preuss are analogous to modern arid environments, such as the Persian Gulf. Furthermore, the alluvial, sabkha, eolian and shallow marine facies of the Preuss are highly similar to facies observed in ancient Martian environments and modern environments on Saturn's moon, Titan.

This thesis takes the form of a meta-criticism of the hermeneutics of the art-historical enterprise. I begin with an immanent critique of the discipline, paying careful attention to where art historians shift the interpretive focus in the spectrum of maker--object--viewer. After advocating for an increase in our consideration for the viewer in the present context, I then present a synoptic reception model for the interpretation of images in both their original forms and reproduced states. These two modes of viewing hinge upon spatial constructions: that of real spaces (e.g., museums, galleries, etc.) and virtual spaces (e.g., the Internet and other ephemeral media). Instead of relegating reproduced images to the art-historical basement, I argue for the productive interpretation of reproductions through a staged theoretical intervention between Jacques Derrida, Hans-Georg Gadamer, and Walter Benjamin. In order to demonstrate the use of my reception model, I conclude with a case study of a particular image--Francisco de Goya's Untitled (Saturn Devouring One of his Children) of 1820-1823. From the painting's beginnings in a farmhouse in Spain through the vicissitudes of nearly 200 years of grafting--from mural to canvas, Madrid to Paris and back again, and as a reproduced image in its "afterlife"--I analyze the aura of the image as imputed by its viewers. I argue that each subsequent reproduction of the image does not necessarily cause a loss of aura, but that conversely and paradoxically, aura actually increases. I analyze the act of viewing itself not as a passive act of visual consumption, but as an interactive process of cumulative production. In this fashion, the reproduced image can play a significant role in the formation of identities and possesses the phenomenological potential to lead to increased self-awareness. / text

This thesis presents a study of the inner plasma disk of Saturn. The results are derived from measurements by the instruments on board the Cassini spacecraft, mainly the Cassini Langmuir probe (LP), which has been in orbit around Saturn since 2004. One of the great discoveries of the Cassini spacecraft is that the Saturnian moon Enceladus, located at 3.95 Saturn radii (1 RS = 60,268 km), constantly expels water vapor and condensed water from ridges and troughs located in its south polar region. Impact ionization and photoionization of the water molecules, and subsequent transport, creates a plasma disk around the orbit of Enceladus. The plasma disk ion components are mainly hydrogen ions H+ and water group ions W+ (O+, OH+, H2O+, and H3O+). The Cassini LP is used to measure the properties of the plasma. A new method to derive ion density and ion velocity from Langmuir probe measurements has been developed. The estimated LP statistics are used to derive the extension of the plasma disk, which show plasma densities above ~20 cm-3 in between 2.7 and 8.8 RS. The densities also show a very variable plasma disk, varying with one order of magnitude at the inner part of the disk. We show that the density variation could partly be explained by a dayside/nightside asymmetry in both equatorial ion densities and azimuthal ion velocities. The asymmetry is suggested to be due to the particle orbits being shifted towards the Sun that in turn would cause the whole plasma disk to be shifted. We also investigate the ion loss processes of the inner plasma disk and conclude that loss by transport dominates loss by recombination in the entire region. However, loss by recombination is still important in the region closest to Enceladus (~±0.5 RS) where it differs with only a factor of two from ion transport loss.

Lightning is an important electrical phenomenon, known to exist in several Solar System planets. Amongst others, it carries information on convection and cloud formation, and may be important for pre-biotic chemistry. Exoplanets and brown dwarfs have been shown to host environments appropriate for the initiation of lightning discharges. In this PhD project, I aim to determine if lightning on exoplanets and brown dwarfs can be more energetic than it is known from Solar System planets, what are the most promising signatures to look for, and if these "exo-lightning" signatures can be detected from Earth. This thesis focuses on three major topics. First I discuss a lightning climatology study of Earth, Jupiter, Saturn, and Venus. I apply the obtained lightning statistics to extrasolar planets in order to give a first estimate on lightning occurrence on exoplanets and brown dwarfs. Next, I introduce a short study of potential lightning activity on the exoplanet HAT-P-11b, based on previous radio observations. Related to this, I discuss a first estimate of observability of lightning from close brown dwarfs, with the optical Danish Telescope. The final part of my project focuses on a lightning radio model, which is applied to study the energy and radio power released from lightning discharges in hot giant gas planetary and brown dwarf atmospheres. The released energy determines the observability of signatures, and the effect lightning has on the local atmosphere of the object. This work combines knowledge obtained from planetary and earth sciences and uses that to learn more about extrasolar systems. My main results show that lightning on exoplanets may be more energetic than in the Solar System, supporting the possibility of future observations and detection of lightning activity on an extrasolar body. My work provides the base for future radio, optical, and infrared search for "exo-lightning".

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The aim of this work is to evaluate the reliability of the urban public transport using as a study case the bus structural corridor in the João Naves de Ávila Avenue, one of the main avenues in Uberlândia, MG, Brazil. Two softwares, Simulation and Assignment of Traffic in Urban Road Networks SATURN and Dynamic Route Assignment Combining User Learning and Microsimulation DRACULA, both developed by the University of Leeds UK, were used to simulate and conclude about the influence of the deployment of the corridor on the bus route. Here it is presented an analysis on the reliability for the public transport along the avenue, where a bus-only lane and thirteen boarding and alighting stations were built, through indicators such as travel time, punctuality and regularity, among others. Through the simulation of various scenarios, this work also presents an analysis on how reliability indicators were affected by the proposed changes. Finally, a comparison between the travel time before and after the construction of the bus corridor allowed a conclusion to be reached on the actual benefits brought on by the deployment of a structural bus corridor in medium sized cities. / Este trabalho tem como objetivo avaliar a confiabilidade do transporte coletivo urbano por ônibus tendo como base o corredor estrutural de ônibus da Avenida João Naves de Ávila, uma das principais vias da cidade de Uberlândia, MG. Para tanto, foram utilizados os programas computacionais Simulation and Assignment of Traffic in Urban Road Networks SATURN e Dynamic Route Assignment Combining User Learning and Microsimulation DRACULA. Os programas, ambos desenvolvidos pela Universidade de Leeds, na Inglaterra, foram usados na execução das simulações necessárias para concluir quanto ao efeito que a implantação do corredor de ônibus acarretou sobre a linha de ônibus que percorre a avenida. É apresentada uma análise sobre a confiabilidade do transporte coletivo urbano na avenida, onde foi implantada uma faixa exclusiva para ônibus e treze estações de embarque e desembarque, por meio de indicadores como tempo de viagem, regularidade e pontualidade, entre outros. Além do cenário básico, foram propostos cenários variados a fim de verificar como os indicadores de confiabilidade seriam afetados. Por fim, esse trabalho traz a comparação entre os tempos de viagem antes e após a implantação do corredor e visa concluir sobre os benefícios reais da implantação de um corredor de ônibus em cidades médias. / Mestre em Engenharia Civil

Parmi les différents plasmas spatiaux, le vent solaire et les magnétogaines planétaires représentent les meilleurs laboratoires pour l’étude des propriétés de la turbulence. Les fluctuations de densité dans le vent solaire étant faibles, à basses fréquences ces dernières sont généralement décrites par la théorie de la MHD incompressible. Malgré son incompressibilité, l’effet de la compressibilité dans le vent solaire a fait l’objet de nombreux travaux depuis des décennies, à la fois théoriques,numériques et observationnels.Le but de ma thèse est d’étudier le rôle de la compressibilité dans les magnétogaines planétaires(de la Terre et de Saturne) en comparaison avec un milieu beaucoup plus étudié et moins compressible (quasi incompressible), le vent solaire. Ce travail a été réalisé en utilisant des données in-situ de trois sondes spatiales, Cassini, Cluster et THEMIS B/ARTEMIS P1.La première partie de mon travail a été consacrée à l’étude des propriétés de la turbulence dans la magnétogaine de Saturne aux échelles MHD et sub-ionique, en comparaison avec celle de la Terre en utilisant les données Cassini et Cluster respectivement. Ensuite j’ai appliqué la loiexacte de la turbulence isotherme et compressible dans le vent rapide et lent en utilisant les données THEMIS B/ARTEMIS P1, afin d’étudier l’effet et le rôle de la compressibilité sur le taux de transfert de l’énergie dans la zone inertielle. Enfin, une première application de ce modèle dans la magnétogaine de la Terre est présentée en utilisant les données Cluster. / Among the different astrophysical plasmas, the solar wind and the planetary magnetosheathsrepresent the best laboratories for studying the properties of fully developed plasma turbulence.Because of the relatively weak density fluctuations (∼ 10%) in the solar wind, the low frequencyfluctuations are usually described using the incompressible MHD theory. Nevertheless, the effectof the compressibility (in particular in the fast wind) has been a subject of active research withinthe space physics community over the last three decades.My thesis is essentially dedicated to the study of compressible turbulence in different plasma environments,the planetary magnetosheaths (of Saturn and Earth) and the fast and slow solar wind.This was done using in-situ spacecraft data from the Cassini, Cluster and THEMIS/ARTEMISsatellites.I first investigated the properties of MHD and kinetic scale turbulence in the magnetosheathof Saturn using Cassini data at the MHD scales and compared them to known features of thesolar wind turbulence. This work was completed with a more detailed analysis performed in themagnetosheath of Earth using the Cluster data. Then, by applying the recently derived exactlaw of compressible isothermal MHD turbulence to the in-situ observations from THEMIS andCLUSTER spacecrafts, a detailed study regarding the effect of the compressibility on the energycascade (dissipation) rate in the fast and the slow wind is presented. Several new empirical lawsare obtained, which include the power-law scaling of the energy cascade rate as function of theturbulent Mach number. Eventually, an application of this exact model to a more compressiblemedium, the magnetosheath of Earth, using the Cluster data provides the first estimation of theenergy dissipation rate in the magnetosheath, which is found to be up to two orders of magnitudehigher than that observed in the solar wind.
