Avec le développement de la méthode adjointe, il est aujourd'hui possible de calculer rapidement, et indépendamment du nombre de paramètres de forme, le gradient des fonctions d'intérêt par rapport à ces paramètres. Cette étude concerne l'utilisation des dérivées ainsi obtenues pour perfectionner les algorithmes d'optimisation locale et globale. Dans une première partie, il s'agit d'utiliser ces gradients pour la construction de modèles de substitution, et de profiter de ces modèles pour réduire le coût des méthodes d'optimisation globale. Plusieurs types de modèles sont présentés et combinés à un algorithme de type " évolution différentielle " en utilisant la méthode EGO (Efficient Global Optimization). Cette procédure est appliquée à l'optimisation de fonctions mathématiques, puis à des cas test d'optimisation aérodynamique autour de profils d'aile. Les résultats sont concluants : l'utilisation d'un modèle de substitution permet de réduire sensiblement le nombre d'évaluations nécessaire du modèle physique, et la prise en compte des gradients accentue ce résultat. Dans la seconde partie de ce travail, la méthode adjointe est utilisée pour calculer le gradient des fonctions d'intérêt par rapport aux coordonnées des noeuds de la surface du profil. Un algorithme d'optimisation locale est alors appliqué en utilisant ces points comme paramètres de l'optimisation et le champ de gradient lissé comme direction de descente. Si l'étude est encore à approfondir, les résultats sont encourageants. optimisation aérodynamique de forme méthode adjointe modèle de substitution krigeage machine à vecteurs de support (SVR) co-krigeage optimisation globale efficace (EGO) amélioration espérée optimisation sans paramétrisation

513	The creation and manifestation of reality through the re-enactment of subconscious conclusions and decisions Opperman, Michiel Christiaan 31 March 2005 (has links) The Creation and Manifestation of Reality-theory was developed for this study. This theory provides an answer to why high functioning people experience problems at work, develop relationship problems, and other dysfunctions that occur in their lives. It provides an explanation as to why this happens: at a certain point in our existence a critical incident (or Initial Sensitising Event) or a series of repeated incidents is perceived by the person as traumatic. During this time of high emotion the child forms a subconscious conclusion, followed by a subconscious decision. The Hypnotic Blueprint is an accumulation of all the different subconscious conclusions and decisions formed over time at a time of intense emotionality, during which the psyche feared for its survival, repressed, gated and banished into the borders of the person's subconscious mind. Numerous other incidents occur through life that reinforce and bolster the original Hypnotic Blueprint. Simultaneously, conflicting ego-states are formed, attempting to balance the state of disequilibrium. Later in life, the original Blueprint is triggered, through the Symptom Activating Event, at a sub-conscious level and starts to operate in the person's life, attracting the circumstances and people who best replay or re-enact the original trauma on a symbolic level. This pattern will be recreated in the person's life, and will most often be the reason why the person enters therapy, or the presenting problem. Life acts as a mirror of the inner world or the psyche of the person. The inner world is mirrored by the other world, or reality. By changing our inner reality, we impact or transform our outer reality. To complete the Creation and Manifestation of Reality-theory, the Imago Developmental Stages identified by Harville Hendrix, were integrated, namely Attachment, Exploration, Identity and Competence. The therapeutic modality suggested is de-hypnotising. The study does not intend to measure the success of the therapy, but rather to establish and test the validity of the Creation and Manifestation of Reality-theory on case studies, using the Life History approach. / Educational Studies / DED(PSYCHOLOGY OF EDUCATION) Creation Manifestation Reality Hypnotic Blueprint Subconscious Conclusion Subconscious Decision Repression Re-Enactment of Patterns Ego-States Imago Relationship Therapy Heart-Centered Hypnotherapy Transpersonal Psychology God 616.8914 Hendrix, Harville Hypnotism--Therapeutic use Subconsciousness Emotions--Psychological aspects Imago relationship theory Interpersonal relations Marital psychotherapy

Above all, it pursues the comparison of two novels Život střídá smrt ("Life Becomes Death") by Petr Prouza and Nebe nemá dno ("Heaven is Bottomless") by Hana Andronikova. Both unique books belong to key Czech novels with the topic of death. Moreover, both of them deal with death from the point of personal experience, which means they are strongly autobiographical. The dissertation concentrates on creative processes and topical aspects, grasps autobiographical elements of both novels and all the identities and differences in the approach to the same topic. Therefore, the dissertation is devoted to listing the works of art dealing with death, further on to the analyses, interpretation and comparison of the novels Život střídá smrt ("Life Becomes Death") and Nebe nemá dno ("Heaven is Bottomless") together with the reflexion of reader's experience.
515	Jointly Ego Motion and Road Geometry Estimation for Advanced Driver Assistance Systems Asghar, Jawaria January 2021 (has links) For several years, there has been a remarkable increase in efforts to develop an autonomous car. Autonomous car systems combine various techniques of recognizing the environment with the help of the sensors and could drastically bring down the number of accidents on road by removing human conduct errors related to driver inattention and poor driving choices. In this research thesis, an algorithm for jointly ego-vehicle motion and road geometry estimation for Advanced Driver Assistance Systems (ADAS) is developed. The measurements are obtained from the inertial sensors, wheel speed sensors, steering wheel angle sensors, and camera. An Unscented Kalman Filter (UKF) is used for estimating the states of the non-linear system because UKF estimates the state in a simplified way without using complex computations. The proposed algorithm has been tested on a winding and straight road. The robustness and functioning of our algorithm have been demonstrated by conducting experiments involving the addition of noise to the measurements, reducing the process noise covariance matrix, and increasing the measurement noise covariance matrix and through these tests, we gained more trust in the working of our tracker. For evaluation, each estimated parameter has been compared with the reference signal which shows that the estimated signal matches the reference signal very well in both scenarios. We also compared our joint algorithm with individual ego-vehicle and road geometry algorithms. The results clearly show that better estimates are obtained from our algorithm when estimated jointly instead of estimating separately. autonomous car ego-vehicle road geometry estimation Advanced Driver Assistance Systems sensor fusion Unscented Kalman Filter.

Using the medium of film, I, therefore, seek to produce knowledge regarding the internalized gaze of the oppressor, and self-objectification, caused by the capitalist heteropatriarchy. Thus, I am drawing from cyborg feminism, and the second wave of sexual difference theory’s concept of becoming, expanded upon by the Italian-Australian philosopher Rosi Braidotti. I further use the French sociologist Pierre Bourdieu’s notion of masculine domination and the American philosopher Gayle Rubin’s charmed circle, in creating a theoretical framework, and using the methods of cultural and feminist film analysis to contextualize the films and locate the subjectification of the women. The movies that I will be analyzing are the Japanese director and poet Sion Sono’s Antiporno (アンチポルノ, 2016) and the Japanese director and photographer Mika Ninagawa’s Helter Skelter (ヘルタースケルター, 2012), which both center around two women and their struggle in becoming-cyborg, in relation to power, trauma, sexuality, technology, and beauty ideals in ‘modernized’ Japan. In that sense, I will study the phenomenon of operating outside the lines of social norms of femininity and desire. internalized gaze of oppression Sion Sono Mika Ninagawa Antiporno Helter Skelter Japanese cinema film analysis gender plastic surgery beauty standards body commodification self-objectification Japan becoming cyborg feminism the charmed circle masculine domination j-horror pinku egia ego guro nansensu shojo manga BDSM Gender Studies Genusstudier
517	Im Spiegel: Eine philosophische Reise zu den Grenzen der Welt Schmidt, Johannes, Rosenthal, Michael 07 November 2013 (has links) Es gibt Situationen, in denen das Leben seine Glaubwürdigkeit verliert. Lukian erfährt dies am eigenen Leib. Er kann nicht glauben, dass sein Großvater gestorben ist. Und dann liegt da auf einmal diese geheimnisvolle Papierrolle unter seinem Bett. Ihr Inhalt stellt all das in Frage, was Lukian bisher selbstverständlich erschien. Was ist der Mensch – nur eine Marionette in einem großen Theaterstück? Die Suche nach Antworten treibt ihn auf eine abenteuerliche Reise zu den Wurzeln unserer Kultur. Er trifft auf die großen Denker der Vergangenheit und diskutiert mit ihnen über die Freiheit des Willens und die Existenz des Ichs. Ein kleiner, unscheinbarer Spiegel begleitet ihn dabei. Zunächst erscheinen in ihm nur rätselhafte Umrisse. Doch nichts bleibt, wie es ist – auf dem Weg zum Ende der Welt. info:eu-repo/classification/ddc/102 ddc:102
518	Subjekt Meißner, Hanna 25 April 2017 (has links) Subjekt ist die folgenreiche Selbstbeschreibung des modernen Menschen, mit der sich dieser als Grundlage von Erkenntnis und als Ursache von Handlungen setzt. Die historischen Ursprünge dieses selbstreferenziellen Verständnisses gehen nicht zuletzt auf Descartes'' Verankerung der Selbstgewissheit des 'Ich' im eigenen Denken zurück und finden in Kants Verortung der Bedingungen der Möglichkeit von Erkenntnis im apriorischen Denkapparat eine paradigmatische Begründung. Seit der zweiten Hälfte des 20. Jahrhunderts erfährt der emphatische Subjektbegriff eine Kritik und wird dezentriert. Insbesondere feministische und postkoloniale Kritiken verweisen auf die inhärente Gewaltsamkeit von Subjektivierungsweisen und deren Begründungen in sexistischen und rassistischen Klassifikationen. info:eu-repo/classification/ddc/301 ddc:301
519	DRONAR: Obstacle echolocation using ego-noise / DRONAR: Egenljudsekolokalisering av hinder Nilsson, Henrik January 2023 (has links) You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. This thesis proposes to use microphones, listening to the drone’s own noise, to estimate the distance to surrounding obstacles. An obstacle echolocation solution for multi-rotor aerial vehicles (MAVs) using ego-noise is developed. The MAV’s noise is captured and auto-correlated to detect echoes at different time delays. This signal is whitened to remove structured measurement noise resulting from the narrow-band components of the MAV’s noise. By recording the MAV’s noise using multiple microphones, a time of arrival (TOA) estimate of the obstacle position is achieved. A beamforming-based solution is used to calculate this estimate. A series of simplified proof-of-concept experiments show that ego-noise echolocation is possible and that the developed solution works in a controlled environment. A prototype implementation of a realistic system is also created. Four signal fusion alternatives are compared, though no best alternative is found for all situations. More work is needed to apply the findings of this work in a robust way, but the principle is shown to work.

520	Alzheimer's Disease Narratives and the Myth of Human Being Rieske, Tegan Echo 11 December 2012 (has links) Indiana University-Purdue University Indianapolis (IUPUI) / The ‘loss of self’ trope is a pervasive shorthand for the prototypical process of Alzheimer's disease (AD) in the popular imagination. Turned into an effect of disease, the disappearance of the self accommodates a biomedical story of progressive deterioration and the further medicalization of AD, a process which has been storied as an organic pathology affecting the brain or, more recently, a matter of genetic calamity. This biomedical discourse of AD provides a generic framework for the disease and is reproduced in its illness narratives. The disappearance of self is a mythic element in AD narratives; it necessarily assumes the existence of a singular and coherent entity which, from the outside, can be counted as both belonging to and representing an individual person. The loss of self, as the rhetorical locus of AD narrative, limits the privatization of the experience and reinscribes cultural storylines---storylines about what it means to be a human person. The loss of self as it occurs in AD narratives functions most effectively in reasserting the presence of the human self, in contrast to an anonymous, inhuman nonself; as AD discourse details a loss of self, it necessarily follows that the thing which is lost (the self) always already existed. The private, narrative self of individual experience thus functions as proxy to a collective human identity predicated upon exceptionalism: an escape from nature and the conditions of the corporeal environment.
