This thesis examines the pop cultural representation of white-collar migrant women (WCMW) through the popular Chinese TV series Ode to Joy. Focusing on various aspects of their lives, this TV series raises many issues about the experiences of WCMW, including perceptions of them as “outsiders” in the megacity, gender inequality, and the tensions between female migrant identity and urban status. This study analyzes those issues by drawing on intersectional theories which examine structural inequalities from the perspective of the interactions of multiple axes of social categories. This thesis asks three major questions: In what way does Ode to Joy represent the experiences of WCMW?; To what extent do issues raised in Ode to Joy impact the wellbeing of WCMW in large cities?, and; What are the “joys” in Ode to Joy for WCMW? In addition to collecting data from the TV series, this study interviewed WCMW informants to provide first-hand accounts of their experiences in an urban culture. By critically analyzing the representation of WCMW characters’ experiences in Ode to Joy, this thesis provides insights on understanding the status of those women in a contemporary Chinese urban setting, thereby filling a gap in academic literature on the pop cultural representation of China’s white-collar migrant women in a Chinese megacity. / Graduate

L'étude des systèmes aux équations différentielles ordinaires vise à prédire le futur des systèmes considérés. La connaissance de l'évolution dans le temps de toutes les variables d' état du modèle permet de prédire de possibles changements radicaux des variables ou des défaillances, par exemple, un moteur peut exploser, un pont peut s'écrouler, une voiture peut se mettre à consommer plus d'essence. De plus, les systèmes dynamiques peuvent contenir des dérivées spatiales et leur discrétisation peut ajouter un très grand nombre d'équations. La résolution des équations différentielles ordinaires est alors une étape essentielle dans la construction des systèmes physiques en terme de dimensionnement et de faisabilité. Le solveur de tels systèmes EDOs doit être rapide, précis et pertinent.En pratique, il n'est pas possible de trouver une fonction continue qui soit solution exacte du problème EDO. C'est pourquoi, des méthodes numériques sont utilisées afin de donner des solutions discrèes qui approchent la solution continue avec une erreur contrôlable. La gestion précise de ce contrôle est très importante afin d'obtenir une solution pertinente en un temps raisonnable.Cette thèse développe un nouveau solveur qui utilise plusieurs méthodes d'amélioration de la vitesse d'exécution des systèmes EDOs. La première méthode est l'utilisation d'un nouveau schéma numérique. Le but est de minimiser le coût de l'intégration en produisant une erreur qui soit le plus proche possible de la tolérance maximale permise par l'utilisateur du solveur. Une autre méthode pour améliorer la vitesse d'exécution est de paralléliser le solveur EDO en utilisant une architecture multicoeur et multiprocesseur. Enfin, le solveur a été testé avec différentes applications d'OpenModelica. / The study of systems of Ordinary Differential Equations aims at predicting the future of the considered systems. The access to the evolution of all states of a system's model allows us to predict possible drastic shifts of the states or failures, e.g. an engine blowing up, a bridge collapsin, a car consuming more gasoline etc. Solving ordinary differential equations is then an essential step of building industrial physical systems in regard to dimensioning and reliability. The solver of such ODE systems needs to be fast, accurate and relevant.In practice, it is not possible to find a continuous function as the exact solution of the real ODE problem. Consequently numerical methods are used to give discrete solutions which approximates the continuous one with a controllable error. The correct handline of this control is very important to get a relevant solution within an acceptable recovery time. Starting from existing studies of local and global errors, this thesis work goes more deeply and adjusts the time step of the integration time algorithm and solves the problem in a very efficient manner.A new scheme is proposed is this thesis, to minimize the cost of integration. Another method to improve the execution speed is to parallelize the ODE solver by using a multicore and a multiprocessor architecture. Finally, the solver has been tested with different applications from OpenModelica.

The demand for using shell theories comes from its efficiency in computational and analytical cost. On another side, new materials that are orthotropic and/or anisotropic in nature are discovered and broadly used in many fields. Many advanced shell theories are developed for these new materials, particularly in the recent decades. A study about the accuracy of these shell theories is very meaningful to build confidence in them for further applications. This study requires a precise benchmark against which shell theories can be tested. This is the main research subjective in this dissertation: to build a set of solutions using the three dimensional (3D) theory of elasticity against which shell theories can be tested for accuracy. The contents of this dissertation to support this research include a comprehensive literature review for the shell theories and recent usage and to find the gaps which need to be filled. These gaps include, among others, the lack of studies on the accuracy of the theories used and the absence of results using the 3D theory, particularly for orthotropic materials. Some of these studies are conducted here. The deficiency of some commercial finite element packages is discussed here. The reasons for the absence of accurate results are investigated. The 3D theory and analyses of isotropic and orthotropic materials of hollow cylinders is investigated here for reliable results.

A nonlinear second order differential equation related to vortex motion is derived. This equation is analyzed using various numerical and analytical techniques including finding approximate solutions using a perturbative approach.

No / Online games require small data of 3D models for low storage costs, quick transmission over the Internet, and efficient geometric processing to achieve real-time performance, and new techniques of facial blendshapes to create natural facial animation. Current geometric modelling and animation techniques involve big data of geometric models and widely applied facial animation using linear interpolation cannot generate natural facial animation and create special facial animation effects. In this paper, we propose a new approach to integrate the strengths of ODE (ordinary differential equation) sweeping surfaces and Newton's second law-based facial blendshapes to create 3D models and their animation with small data, high efficiency, and ability to create special facial effects.

Mathematische Modellierung ist ein wichtiges Werkzeug biologischer Forschung geworden, was sich in der Entstehung von Systembiologie widerspiegelt. Eine erfolgreiche Anwendung mathematischer Methoden auf biologische Fragen erfordert die Zusammenarbeit zwischen experimentell und theoretisch arbeitenden Wissenschaftlern, auch um sicherzustellen, dass die Biologie im Modell adäquat dargestellt wird. Ich präsentiere hier zwei Untersuchungen zur Anpassung von Saccharomyces cere- visae an hyperosmotische Bedingungen: Eine biologisch detailgetreue Beschreibung der Signaltransduktion zur Aktivierung von Hog1 und ein Model, das Anpassung an osmotischen Stress in zellulärem Zusammenhang beschreibt. Die Studie zur Osmoadaptation in zellulären Kontext impliziert, dass Hog1 und Fps1, zwei wichtige Bausteine dieses Adaptationsvorgangs, miteinander in Wechselwirkung treten und dies zur Anpassung beiträgt. Dieses Ergebnis wird durch die Integration verschiedener Hefestämme mit zum Teil gegensätzlich wirkenden Mutationen ermöglicht. Diese Studie offenbart des weiteren, dass die Rolle von Glycerol in der langfristigen Anpassung bisher überschätzt wurde. Die hier präsentierten Ergebnisse zeigen, dass Glycerol als ’Not’-Osmolyt eingesetzt wird und andere Stoffe, z.B. Trehalose, erheblich zu dauerhafter Osmoadaptation beitragen. Durch die Betrachtung des Zustands mehrerer zellulärer Mechansimen wird deutlich, dass Osmoadaptation stark vom Kontext abhängig ist und nicht perfekt ist. Der Preis schlägt sich in langsamerem Wachstum nieder. Zeitabhängige Sensitivitätsanalyse des Modells untermauert diese Hypothese. Die gewählte Perspektive ermöglicht die Betrachtung von intrazellulären Signaltransduktionskomponenten, Metaboliten und des Wachstums. Der Vergleich mit einer Studie, die Anpassung an osmotischen Stress als perfekte Adaptation auf Grund eines vereinfachten Modells beschreibt, hebt die Rolle der gewählten Perspektive zum Verständnis biologischer Systeme hervor. / Mathematical modeling has become an important tool in biology, reflected in the emergence of systems biology. Successful application of mathematical methods to biological questions requires collaboration of experimental and theoretical scientists to identify and study the problem at hand and to ensure that biology and model match. In this thesis, I present two studies on adaptation to hyperosmotic conditions in the yeast Saccharomyces cerevisae: A biologically faithful description of the signaling pathways activating Hog1 and a model integrating the effects of Hog1-activity and cellular metabolism, describing osmoadaptation in cellular context. The study of osmoadaptation in cellular context suggests that Hog1 and Fps1, two crucial components of adaptation, interact upon hyperosmotic stress. This finding is facilitated by incorporating multiple strains with mutations leading to partly oppositional phenotypes. This study further reveals that the role of glycerol in long term adaptation has been overestimated so far. According to the results presented here, glycerol is utilized as an ’emergency’ osmoprotectant and other compounds, e.g. trehalose, contribute significantly to osmoadaptation. Accounting for the state of multiple cellular mechanisms (Hog1-activity, glycolysis, growth) shows that adaptation to hyperosmotic stress and the impact of the individual mechanisms of adaptation is context dependent and that adaptation to sustained osmostress is not perfect, the expense reflected in a reduced growth rate in hyperosmotic medium. Time-dependent sensitivity analysis supports the notion of context. The perspective chosen allows observations on intracellular signaling components, metabolites and growth speed. Comparison with a study that describes osmoadaptation as perfect adaptation highlights the role of this perspective for the conclusions drawn, thus emphasizing the importance of an integrative perspective for understanding biological systems.

Das Ziel der Diplomarbeit bestand darin eine Testumgebung zur Orchestrierung von Geo Web Services aufzubauen. Dabei diente die Diplomarbeit "Orchestrierung von Web Services" von Jäger/Weidenhagen als Grundlage. Um ein Verständnis für dieses Gebiet zu bekommen, werden zu Beginn die Grundlagen betrachtet. Rechtliche Aspekte zum Thema Orchestrierung werden angegeben, um die Wichtigkeit des Themas zu unterstreichen. Eingängige Standards wie SOAP und WSDL werden in ihren Kernpunkten erläutert. Insbesondere bei SOAP wird näher darauf eingegangen. Neben den OWS besteht auch die Möglichkeit Geo-Datenbanken in Diensteketten einfließen zu lassen. Dafür werden exemplarisch Dienste aufgesetzt, die dies ermöglichen. Weiterhin werden die Benutzerschnittstellen von Web Services (und auch Diensteketten) untersucht. Die Option eines Clients mittels Scriptsprachen wird beschrieben. Dabei erwies sich PHP am geeignetsten. Auf diese Weise kann für jede Dienstekette eine dynamische Webseite gestaltet werden, die eine graphische Schnittstelle für den Nutzer bietet.
