This essay aims to examinate how the dead woman is described in three swedish crime fiction- novels. The novels included in my study is Stieg Larsson ́s Män som hatar kvinnor, Mons Kallentoft ́s Den femte årstiden and Lars Kepler ́s Stalker. The purpose of this study is to examine these questions: how is the dead woman described, how does the woman relate to prevailing norms in a sex-normative context, who is the dead woman based on socio-cultural identity and how can the killer ́s identity be understood in relation to the victim? Inspired by Judith Butler ́s performativity theory I assume a gender constructivist perspective, that gender is a social construction. I am also inspired of Maria Nikolajeva ́s gender role schedule, which shows what characteristics women are most often attributed in literature. I also add my own properties to the schedule. Thus, the result shows that the dead woman fulfills all conventional female standards. The dead woman is, based on the material, either an unwanted woman or an desired woman. The unwanted woman is subjected to sexual violence, something that the desired woman avoids. When the women are dead, they still meet conventional standards even though their bodies are completely destroyed by their perpetrators. The identity of the murderers can be understood from socio-cultural status and their motives. / Denna uppsats undersöker hur den döda kvinnan beskrivs i tre svenska deckare: Stieg Larssons Män som hatar kvinnor, Mons Kallentofts Den femte årstiden och Lars Keplers Stalker. Syftet med uppsatsen är att besvara dessa frågor: hur beskrivs den kvinna som ska dödas och som sedan dör, hur relaterar kvinnorna som ska dödas och sedan dör till rådande kvinnliga normer i en könsnormativ kontext, vem är den döda kvinnan och hur kan mördarens identitet förstås i relation till offret? För att besvara dessa frågor utgår jag från att kön är en social konstruktion och Judith Butlers performativitetsteori. Dessutom används Maria Nikolajevas könsrollsschema för hur kvinnor oftast skildras i litteratur. Resultatet visar att den döda kvinnan går att dela upp i två kategorier; den önskade kvinnan och den oönskade kvinnan. Båda kategorier av kvinnor relaterar till rådande kvinnliga normer. Den oönskade kvinnan har ingen plats i samhället, lever ensam och utsätts för sexuellt våld innan hon mördas. Den önskade kvinnan fyller en funktion i samhället, saknas av någon när hon dör och utsätts inte för sexuellt våld innan hon mördas. Den döda kvinnan uppfyller alla kvinnliga normer utifrån Nikolajevas schema, oavsett vilken kategori hon tillhör. Mördarnas identiteter går att förstå utifrån socioekonomisk status samt val av offer.

Capture-évolution-éjection de particules par des systèmes binaires (étoile-planète, étoile binaire, étoile-trou noir supermassif, trou noir binaire, ...). Dans une première partie, en utilisant une généralisation de l'application de Kepler, nous décrivons, au travers du cas de 1P/Halley, la dynamique chaotique des comètes dans le système solaire. Le système binaire, alors considéré, est composé du Soleil et de Jupiter. L'application symplectique utilisée permet de rendre compte des différentes caractéristiques de la dynamique : trajectoires chaotiques, îlots invariants de KAM associés aux résonances avec le mouvement orbital de Jupiter,... Nous avons déterminé de façon exacte et semi-analytique l'énergie échangée (fonction kick) entre le système solaire et la comète de Halley à chaque passage au périhélie. Cette fonction kick est la somme des contributions des problèmes à trois corps Soleil-planète-comète associés aux 8 planètes du système solaire. Nous avons montré que chacune de ces contributions peut être décomposée en un terme keplerien associé au potentiel gravitationnel de la planète et un terme dipolaire dû au mouvement du soleil autour du centre de masse du système solaire. Dans une deuxième partie, nous avons utilisé la généralisation de l'application de Kepler pour étudier la capture de particules de matière noire au sein des systèmes binaires. La section efficace de capture a été calculée et montre que la capture à longue portée est bien plus efficace que la capture due aux rencontres proches. Nous montrons également l'importance de la vitesse de rotation du système binaire dans le processus de capture. Notamment, un système binaire en rotation ultrarapide accumulera en son sein une densité de matière jusqu'à 10^4 fois celle du flot de matière le traversant. Dans la dernière partie, en intégrant les équations du mouvement du problème à trois corps restreint plan, nous avons étudié l'éjection des particules capturées par un système binaire. Dans le cas d'un système binaire dont les deux corps sont de masses comparables, alors que la majorité des particules sont éjectées immédiatement, nous montrons, sur les sections de Poincaré, que la trace des particules restant indéfiniment aux abords du système binaire forme une structure fractale caractéristique d'un répulseur étrange associé à un système chaotique ouvert. Cette structure fractale, également présente dans l'espace réel, a une forme de spirale à deux bras partageant des similitudes avec les structures spiralées des galaxies comme la nôtre. / This work is devoted to the study of the restricted 3-body problem and particularly to the capture-evolution-ejection process of particles by binary systems (star-planet, binary star, star-supermassive black hole, binary black hole, ...). First, using a generalized Kepler map, we describe, through the case of 1P/Halley, the chaotic dynamics of comets in the Solar System. The here considered binary system is the couple Sun-Jupiter. The symplectic application we use allows us to depict the main characteristics of the dynamics: chaotic trajectories, KAM islands associated to resonances with Jupiter orbital motion, ... We determine exactly and semi-analytically the exchange of energy (kick function) between the Solar System and 1P/Halley at its passage at perihelion. This kick function is the sum of the contributions of 3-body problems Sun-planet-comet associated to the eight planets. We show that each one of these contributions can be split in a keplerian term associated to the planet gravitational potential and a dipolar term due to the Sun movement around Solar System center of mass. We also use the generalized Kepler map to study the capture of dark matter particles by binary systems. We derive the capture cross section showing that long range capture is far more efficient than close encounter induced capture. We show the importance of the rotation velocity of the binary in the capture process. Particularly, a binary system with an ultrafast rotation velocity accumulates a density of captured matter up to 10^4 times the density of the incoming flow of matter. Finally, by direct integration of the planar restricted 3-body problem equations of motion, we study the ejection of particles initially captured by a binary system. In the case of a binary with two components of comparable masses, although almost all the particles are immediately ejected, we show, on Poincaré sections, that the trace of remaining particles in the vicinity of the binary form a fractal structure associated to a strange repeller associated to chaotic open systems. This fractal structure, also present in real space, has a shape of two arm spiral sharing similarities with spiral structures observed in galaxies such as the Milky Way.

Há três décadas, os sistemas de informação corporativos eram projetados para apoiar a execução de tarefas pontuais. Atualmente, esses sistemas também precisam gerenciar os fluxos de trabalho (workflows) e processos de negócio de uma organização. Em comunidades científicas de físicos, astrônomos, biólogos, geólogos, entre outras, seus sistemas de informações distinguem-se dos existentes em ambientes corporativos por: tarefas repetitivas (como re-execução de um mesmo experimento), processamento de dados brutos em resultados adequados para publicação; e controle de condução de experimentos em diferentes ambientes de hardware e software. As diferentes características dos dois ambientes corporativo e científico propiciam que ferramentas e formalismos existentes ou priorizem o controle de fluxo de tarefas, ou o controle de fluxo de dados. Entretanto, há situações em que é preciso atender simultaneamente ao controle de transferência de dados e ao controle de fluxo de tarefas. Este trabalho visa caracterizar e delimitar o controle e representação do fluxo de dados em processos de negócios e workflows científicos. Para isso, são comparadas as ferramentas CPN Tools e KEPLER, que estão fundamentadas em dois formalismos: redes de Petri coloridas e grafos de workflow orientados a atores, respectivamente. A comparação é feita por meio de implementações de casos práticos, usando os padrões de controle de dados como base de comparação entre as ferramentas. / Three decades ago, business information systems were designed to support the execution of individual tasks. Todays information systems also need to support the organizational workflows and business processes. In scientific communities composed by physicists, astronomers, biologists, geologists, among others, information systems have different characteristics from those existing in business environments, like: repetitive procedures (such as re-execution of an experiment), transforming raw data into publishable results; and coordinating the execution of experiments in several different software and hardware environments. The different characteristics of business and scientific environments propitiate the existence of tools and formalisms that emphasize control-flow or dataflow. However, there are situations where we must simultaneously handle the data transfer and control-flow. This work aims to characterize and define the dataflow representation and control in business processes and scientific workflows. In order to achieve this, two tools are being compared: CPN Tools and KEPLER, which are based in the formalisms: colored Petri nets and actors-oriented workflow graphs, respectively. The comparison will be done through implementation of practical cases, using the dataflow patterns as comparison basis.

Durant cette thèse, nous avons principalement travaillé sur deux sujets liés à l'analyse de la performance GPU (Graphics Processing Unit - Processeur graphique). Dans un premier temps, nous avons développé une méthode analytique et un outil d'estimation temporel (TEG) pour prédire les performances d'applications CUDA s’exécutant sur des GPUs de la famille GT200. Cet outil peut prédire les performances avec une précision approchant celle des outils précis au cycle près. Dans un second temps, nous avons développé une approche pour estimer la borne supérieure des performances d'une application GPU, en se basant sur l'analyse de l'application et de son code assembleur. Avec cette borne, nous connaissons la marge d'optimisation restante, et nous pouvons décider des efforts d'optimisation à fournir. Grâce à cette analyse, nous pouvons aussi comprendre quels paramètres sont critiques à la performance. / In this thesis work, we have mainly worked on two topics of GPU performance analysis. First, we have developed an analytical method and a timing estimation tool (TEG) to predict CUDA application's performance for GT200 generation GPUs. TEG can predict GPU applications' performance in cycle-approximate level. Second, we have developed an approach to estimate GPU applications' performance upper bound based on application analysis and assembly code level benchmarking. With the performance upper bound of an application, we know how much optimization space is left and can decide the optimization effort. Also with the analysis we can understand which parameters are critical to the performance.

Utilizing data from the Kepler Mission, we analyze a flickering phenomenon in the symbiotic variable star CH Cygni. We perform a spline interpolation of an averaged lightcurve and subtract the spline to acquire residual data. This allows us to analyze the deviations that are not caused by the Red Giant’s semi-regular periodic variations. We then histogram the residuals and perform moment calculations for variance, skewness, and kurtosis for the purpose of determining the nature of the flickering. Our analysis has shown that we see a much smaller scale flickering than observed in the previous literature. Our flickering scale is on the scale of fractions of a percent of the luminosity. Also, from our analysis, we are very confident that the flickering is a product of the accretion disc of the White Dwarf.

O livro é composto na forma de uma narrativa histórica daquela que o astrônomo chamou sua guerra contra Marte, trabalho exaustivo de análise e interpretação dos dados previamente coletados pelo grande observador Tycho Brahe que teve como resultado a descoberta das duas primeiras leis dos movimentos planetários que levam o nome de Kepler. Mostramos que, à luz da Defesa de Tycho contra Ursus, tratado póstumo escrito por Kepler cerca de uma década antes da publicação da Astronomia nova, a estrutura narrativa desta última revela-se como a exposição de um método de pesquisa, segundo o qual o astrônomo percorreu o caminho que leva dos movimentos observados do planeta à determinação de seu percurso real em torno do Sol. Procuramos destacar os principais elementos constituintes deste método, reconstruindo o caminho que leva à descoberta da forma elíptica da órbita do planeta / Abstract: We present an exposition on the New astronomy, published by the german astronomer Johannes Kepler in 1609. The book is composed in the form of a historical narrative of Kepler's war on Mars, exhaustive work of analysis and interpretation of data relative to the planet previously collected by the great obderver Tycho Brahe, which resulted on the discovery of the two first laws of planetary motion that bear Kepler¿s name. We have shown here that in light of Tycho¿s defence against Ursus, posthumous work written by Kepler about a decade before the publication of the New astronomy, the historical narrative presented in the latter is the blueprint of a method, by means of which the astronomer derived the true orbit of Mars around the Sun from the observed motions of the planet. We have attempted to provide an account of the main elements of this method, reconstructing the path that leads to the discovery of the elliptical shape of the planet's orbit / Doutorado / Doutor em Filosofia

Harmony, in a mathematical context, refers to proportion, order and symmetry. In a musical context, harmony indicates a logical succession of the sounds. In a spiritual context, it denotes an approach to the divine, peace. Johannes Kepler´s work Harmonices mundi (1619) presents a harmonious composition of these three contexts set in the astronomical scene of the seventeenth century. In this book Kepler shows the existing mathematical relation between the planets periods of revolution and their respective distances from the Sun or as we know at the present time, the third law of the planetary motion, harmonic law, or Kepler s third law. Based on his own previous conclusions, essentially the ones published in Mysterium Cosmographicum (1596), and on the hypothesis of a relationship between the musical note frequency and the velocities of the planets in its orbits, Kepler made use of a theoretical structure typical of his period, which includes the Pythagoras mystics, the Platonic philosophy, the Euclidian geometry, the Ptolemaic music theory, and the Copernican heliocentricism. The aim of this dissertation is to examine the theoretical and epistemological basis used by Kepler on the development of the harmonic law , and to discuss its significance in the keplerian cosmology and for the astronomy of the period / Um dos significados da palavra consonância é harmonia. Harmonia, no contexto matemático, remete-se a proporção, ordem e simetria. No contexto musical, harmonia indica uma sucessão lógica dos sons. No contexto espiritual, denota aproximação com o divino, paz. A obra de Johannes Kepler (1571 1630), Harmonices mundi (1619), é uma composição harmoniosa destes três contextos aplicados ao cenário astronômico do século XVII. É neste livro que Kepler apresenta a relação matemática existente entre os períodos de revolução dos planetas e suas respectivas distâncias em relação ao Sol ou como conhecemos nos dias atuais, terceira lei do movimento planetário, lei harmônica ou terceira lei de Kepler. Baseando-se em suas conclusões anteriores, principalmente as que foram publicadas no Mysterium Cosmographicum (1596), e na hipótese de uma ligação entre as freqüências das notas musicais e as velocidades assumidas pelos planetas ao longo de suas trajetórias, Kepler utilizou-se de um arcabouço teórico característicos de sua época: a mística pitagórica, a filosofia platônica, a geometria euclidiana, a teoria musical de Ptolomeu e o heliocentrismo de Copérnico. O objetivo desta dissertação é examinar a fundamentação teórica e epistemológica empregada por Kepler na elaboração da lei harmônica , bem como discutir sua relevância na cosmologia kepleriana e para a astronomia da época
