Ego-motion sensors are commonly used for pose estimation in Simultaneous Localization And Mapping (SLAM) algorithms. Inertial Measurement Units (IMUs) are popular sensors but suffer from integration drift over longer time scales. To remedy the drift they are often used in combination with additional sensors, such as a LiDAR. Pose estimation is used when scans, produced by these additional sensors, are being matched. The matching of scans can be computationally heavy as one scan can contain millions of data points. Methods exist to simplify the problem of finding the relative pose between sensor data, such as the Normal Distribution Transform SLAM algorithm. The algorithm separates the point cloud data into a voxelgrid and represent each voxel as a normal distribution, effectively decreasing the amount of data points. Registration is based on a function which converges to a minimum. Sub-optimal conditions can cause the function to converge at a local minimum. To remedy this problem this thesis explores the benefits of combining IMU sensor data to estimate the pose to be used in the NDT SLAM algorithm.

<p>En este trabajo nos proponemos analizar tres diferentes versiones de una misma historia que le sucede al alter ego de la escritora y periodista española Rosa Montero a mediados de los años setenta. La historia, en sus tres versiones, es contada por este alter ego en la novela <em>La loca de la casa </em>(2003). Nuestro objetivo es demostrar la importancia que la memoria colectiva de España ha tenido para la memoria individual del narrador personaje. Los hechos que le suceden a este alter ego de Montero no habrían tenido lugar si en la España de los años setenta del pasado siglo no hubiesen ocurrido ciertos acontecimientos que los españoles de la generación de la escritora recuerdan muy bien, y que hoy forman parte de la memoria colectiva de la nación. Con la ayuda de este estudio veremos cómo la autora juega con la historia de su vida, mostrándonos que las cosas no siempre son lo que aparentan en el mundo de la literatura. También vamos a analizar el papel de algunos de los personajes secundarios del libro, de gran importancia para el análisis. Hay que subrayar que hemos optado por centrarnos en las partes más autobiográficas de la novela, ya que estas son las que más tienen que ver con la memoria y la imaginación. En este análisis penetramos el mundo de la memoria y la literatura y, al mismo tiempo, el del olvido.</p>

Decisions are performatives - or at least, they share important features with performative utterances that can elucidate our theory of what type of thought they are, and what they do. Namely, decisions have an analogous force to that of performatives, where the force of a propositional attitude or utterance is constituted by (i) its point, or purpose, which is mainly a matter of its direction-of-fit, and (ii) its felicity conditions. The force of both decisions and performatives is to bring into being the states of affairs represented in their intentional contents, merely in virtue of the decision or performative’s occurrence and the satisfaction of the felicity conditions they presuppose. The first chapter of the thesis explicates this general framework, and the second and third attempt to show some of the work it can do for a theory of decisions.

This study is designed to investigate the relationships among affective and cognitive personal qualities leading to psychological resilience among natural disaster survivors. The main assumption of this study is that positive personal qualities might be associated with better psychological adjustment. The study aimed at testing a hypothesized theoretical model accounting for resilience with regard to personal qualities. The sample for this study was composed of individuals who were exposed to earthquakes that occurred in 1999 in Marmara region of Western Turkey. The study hypothesized that the dispositional cognitive and affective constructs (hope, optimism, life satisfaction, self esteem and positive affect) play vital roles in pathways to psychological resilience. Initially hypothesized model based on cognitive-behavioral theoretical foundations was proposed and tested. The cognitive behavior approach holds the idea that thoughts are the determinants of functional and dysfunctional emotions and behaviors. In the model, global self esteem serve as an underlying mechanism that helps to human operate well on the environment. The positive influence of global self esteem can be observed in cognitive process and affective domain in individuals. Simultaneously a person develops an optimistic worldview based on the global self esteem. Self esteem leads a person to construe positive cognitive constructs influencing the general world of view positively and utilize those cognitive. Since thinking patterns influence the affective side of the person, if the person utilizes positive cognitive constructs while interpreting life events, he or she is likely to experience more positive feelings and to be satisfied with life at the same time The hypothesized model was trimmed. Dispositional hope (pathways and agentic thinking), optimism, positive affect, life satisfaction and self-esteem were regarded as independent latent variables while three factors of psychological resilience were valued as the latent dependent variables. Finally, a structural model was suggested to account for the pathways leading to resilience among the Turkish disaster survivors. According to the model, self esteem, dispositional hope and optimism have indirect effect on resilience components via positive affect and life satisfaction. For purposes, the Ego Resilience Scale was adapted into Turkish. Exploratory factor analysis yielded three-factor solution for Turkish disaster survivors and the resilience factors were labeled as Personal Strengths Relating Recovery / Positive Self-Appraisals and Openness to New Experience. The results revealed that the Ego Resiliency Scale is a validated and reliable measure of psychological resilience among Turkish disaster survivors.

Well-being at work is of major public interest, and justice at the workplace can be a key factor contributing to employees and managers feeling well. Research has found direct relationships between organizational justice perceptions and work and health outcomes. With research on the justice–health link still emerging, this thesis examines the moderating and mediating processes for the effects of justice perceptions on work outcomes and especially health outcomes. As little is known about those who enact justice, the antecedents and consequences of justice enactment are also studied. In Study I, the relationships between organizational justice and work and health outcomes were in focus, as the moderating role of job characteristics was investigated utilizing the demand–control(–support) model. Organizational justice and job characteristics were associated with work and health outcomes within and across time. The multiplicative effects showed that the organizational justice effects were stronger when perceived job demands were high, job control was low or social support was low. Study II examined the processes through which justice perceptions translate into health outcomes. Building on the allostatic load model, mental preoccupation with work was found to be a relevant mediator of the justice–health relationship, with locus of control moderating the mediated relationships. Study III focused on the actor perspective. Investigating predictions based on the deontic model of justice and ego-depletion theory, moral regard and justice self-efficacy predicted justice enactment positively, and justice enactment had positive effects on feeling professionally recognized but also negative health consequences for the actors themselves. This thesis contributes to advancing the emergent justice–health research stream by providing insights into the processes underlying these aspects, and by incorporating this stream into the actor perspective. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 3: Submitted.</p>

Ce travail, correspondant à l'un des trois volumes de mon Habilitation à Diriger des recherches soutenue le 20 novembre 2012 à l'Université Paris1-Sorbonne, expose les différentes étapes de mon itinéraire scientifique. Il permet de porter un regard réflexif sur les travaux antérieurs et de proposer de nouvelles thématiques pour les années à venir.

Les travaux conduits dans le cadre de cette thèse ont pour but d'étendre le champ de validité des simulations de trafic en milieu urbain et péri-urbain, avec notamment une meilleure prise en compte du contexte de conduite, de l'hétérogénéité des véhicules (deux-roues motorisés, véhicule léger, poids lourd, etc.) et des comportements des conducteurs en termes d'occupation de l'espace au sol. Le but est de produire en simulation des comportements observés en situation réelle tels que les phénomènes de faufilement (deux-roues, véhicules d'urgence, cas des intersections). Nous abordons, la simulation du trafic routier en considérant une approche comportementale fondée sur les systèmes multi-agents. Des travaux précédents ont proposé des solutions non génériques, notamment pour le cas particulier des deux-roues motorisés. Nous proposons un nouveau modèle d'agent permettant de mieux prendre en compte le contexte de conduite et les comportements des conducteurs en termes d'occupation de l'espace. Nous dotons l'agent d'une représentation ego-centrée de l'environnement fondée sur le concept d'affordance. Nous utilisons ainsi les affordances pour identifier les actions possibles, en termes d'occupation de l'espace, offertes par l'environnement. Nous les utilisons en- suite pour construire une représentation ego-centrée de la situation. Le modèle d'agent proposé a été implémenté avec Archisim. Cette implémentation a permis de reproduire une situation de trafic réelle et de comparer les données simulées avec celles recueillies sur le terrain. Différentes expérimentations ont été menées afin d'évaluer la qualité de la solution proposée.
