Повний текст джерелаDespite the current abilities of our communication technologies, they remain unable to completely counterbalance feelings of isolation and loneliness. Social touch is essential to human well-being and allows us to develop and strenghten our relationships. It is also powerful channel of emotional communication. This thesis work is aimed at endowing artificial agents with social touch abilities. Whether they are robotic or virtual artificial agents represent new kinds of social entities and are already equipped with many interactional modalities (speech, gestures, facial expressions, etc.). Endowing them with touching abilities could further enhance their abilities to communicate emotions and to bond with humans. More specifically, our main research question is to determine when and how to touch a human is meaningful, autonomous and respectful way. To answer this question, we propose a theoretical structure and a functional implementation of a touching agent, able to dynamically interact with a human in real-time in an immersive environment. We describe a perception module to detect the human’s behaviour, a decision model able to take coherence and acceptability of touch into account, and a haptic interface (SOFTLY) that can be used in the immersive setup to generate haptic feedback. Evaluations of this framework are discussed and hightlight that its abilities are promising, althought there are still clear avenues of improvement for the model

Повний текст джерелаUndulatory wave-based self-propulsion like used by fish may be a suitable alternative to traditional propeller-based propulsion for underwater vehicles. The use of undulatory propulsion implies a certain degree of structural flexibility will be present, hence consideration of both fluid and structure is critical to assessing the behavior of this form of propulsion. In this thesis, a novel segregated fluid-structure interaction (FSI) coupling scheme is developed between a finite element structure solver and a 2D unsteady panel method fluid solver with discrete vortex particle wake approach. The different components of the FSI solver are validated first individually and then as a whole using the case of a flexible two-dimensional plate in pure heave. The scaling law relating input swimming variables and the resulting swimming speed is then reproduced and the importance of drag to these relations is elucidated.A self-propelled swimmer whose beam-like structure and rigid body motions are resolved is then examined under the influence of an imposed bending moment distribution. A curvature-based, delayed proprioceptive feedback is then applied to deform the self-propelled swimmer. Feedback based swimming was found to be distinct from active, imposed bending moment swimming. A simplified one degree of freedom model was found to qualitatively describe the feedback swimmer behavior. A swimmer using muscle-like elements is then assessed to determine the relative importance of different muscle properties with the aim of identifying if the non-linear behavior of muscles is beneficial to self-propulsion. Finally, a three-dimensional, thin plate in pure heave is examined with the aim of determining to what extent an 3D panel method can be used in lieu of computationally expensive viscous flow approaches self-propulsion analysis in 3D

Повний текст джерелаThis dissertation focuses on the interaction in asylum application hearings in Belgium and the written texts generated from this procedure, namely, written accounts of the hearings and decisions. The first goal of this research is to identify the officials’ interactional and discursive practices which may be detrimental to the administration of justice, either because they are prejudicial to the success of the applications, or because they make the asylum agencies’ task of assessing credibility difficult. “Interactional practices” refers to the ways in which officials interact with applicants in the hearings and “discursive practices” refers to the ways of putting the applicants’ statements in writing. The second aim is to check whether the criminalization of the asylum seeker observed by previous studies in the discourse of politicians and in the mass media can be detected at an interactional level and in the way of examining the applications. In order to carry out this research, the entire trajectories of twelve applicants in Belgium were followed, that is, all their hearings, conducted in French, were recorded, and compared with the corresponding written accounts and decisions.

Повний текст джерелаL'objectif de cette thèse était de contrôler un robot porte-endoscope grâce à primitives de commandes " haut-niveau " qui imitent la tâche de l'assistant chargé de manipuler l'endoscope en cœlioscopie classique. Dans un premier temps, j'ai construit un modèle du domaine de la chirurgie cœlioscopie mettant en évidence le rôle de l'assistant qui m'a permis de déterminer les commandes pertinentes pour contrôler un robot porte-endoscope. Je me suis ensuite intéressée à la mise en œuvre de ces commandes, notamment l'une d'entre elles, consacrée au suivi automatique, par le robot, des instruments chirurgicaux à partir de l'analyse des images endoscopiques. La détection des instruments chirurgicaux a d'abord été validée sur des images numérisées de procédures chirurgicales, puis nous avons réalisé un test sur cadavre, plus proche de la réalité clinique, au cours duquel nous avons réussi à suivre un instrument chirurgical avec le robot porte endoscope.

Повний текст джерелаIn front of the question of possible health effects of electromagnetic fields, and especially those that are caused by use of mobile phone, many research programs have begun in France and all over the world. Thus, this thesis is in the framework of the study of interaction of electromagnetic waves with the biological matter, and relates more precisely to numerical dosimetry. This one is made with an FDTD code. The study of head-phone interaction makes it possible to characterise the standard exposure of a cellular telephone. Thus, the need to use a realistic model of head, in order to take account of the heterogeneity of this last one, led us to realise a numerical model of head with MRI images. Before the dosimetric studies, evolutions have been brought to FDTD code and particular points have been studied: the excitation source, PML boundary condition and uncertainties of the SAR calculation. Then, the influence of the antenna and its position, like the phone position and the use of the hand-free kit, have been observed. The helix antenna is largely used in mobile telephony. To realise a dosimetric study of head-phone system with this antenna, an equivalent model, based on the self-inductive properties of the helix, has been developed. Concerning the exposure systems, we have been interested in a 'localised' system, with a loop antenna. In the framework of the COMOBIO project, French program of the RNRT, this system have been studied and it makes it possible to expose a rat under conditions which approach a standard exposure of cellular phones. At 900 MHz, the influence of the rat's model on the dosimetry of this system has been observed. Moreover, the adaptation of the system to the various frequencies of mobile telephony has been studied, like his dosimetry at 1800 MHz. A second system called 'whole body', using an horn antenna, has also been studied. The performances of those exposure systems have been compared with a plane wave illumination (device 'whole body') and carrousel (device 'head only')

Повний текст джерелаMarseille is changing. For the past twenty years, the city has been investing in various “globalised” sectors, aiming to improve its prospects and rejuvenate its image. Among the transformations that this initiative has led to, the growth of the tourism industry is a notable example. Throughout its history, Marseille has gained a reputation for being a port of call for different migrant populations. How is the city reacting to the arrival of a new form of globalised mobility? What traces does this tourist mobility leave on its sociolinguistic fabric? This thesis aims to address these questions by exploring the links between social dynamics and language use in a setting central to Marseille’s tourist sector: the Marseille Tourist Office and Convention Bureau. Through interactional analyses of encounters between international tourists and tourist advisers, this research proposes a critical look at how language resources are deployed in this context. Special focus is given to analysing how participants select the language of interaction and it is shown how a “sociolinguistic dynamic of efficiency” and a “sociolinguistic dynamic of commodification” underpin these negotiations. These dynamics will be shown to favour, and therefore add value to, a repertoire made up of very few linguistic resources. It will be shown how the language practices in this situation become a part of the touristic context and how they may be considered as a manifestation of the inequality linked to globalisation processes

Повний текст джерелаThis work aims to be a contribution to the numerical techniques used in air quality modelling. Our new multiscale model "MAPOM" (Multiscale Air Pollution Model) simulates mesoscale atmospheric pollutant dispersion. To increase the model accuracy, a new mesh embedding method, allowing grid interactions at the interface, has been implemented and tested. Mass conservation, positivity, and monotonicity are ensured. MAPOM was validated on theoretical test cases. It was then applied over the area of Marseille - Etang de Berre (ESCOMPTE domain). The model and its interactive mesh embedding algorithm were proved to be efficient in handling difficult problems of air quality at mesoscale over complex terrain. The optimization of the memory, and the modular structure of this new model enable a flexible, fast and automatic management of the nested grids, and of the physical and chemical processes

Повний текст джерелаThe work of this thesis consists of two axes. The first concerns the study of interactions of a large number of solitons in fiber laser and the second is the realization of high-power single-mode fiber laser. We observed experimentally different states in a ring fiber laser mode-locked by nonlinear rotation of polarization, where the pulses are under disordered movements, others where the movement is collective. We have identified 5 different states. We point out an analogy with the states of the matter and propose for the first time a classification of dissipative soliton complexes : soliton gas, supersonic soliton gas flow, soliton liquid, soliton pottery stat and soliton crystal. We have investigated multiple-soliton pattern formations in a figure-of-eight fiber laser passively mode-locked through non linear amplifying loop mirror. We have obtained a variety of soliton patterns and states that were previously observed in double-clad fiber lasers passively mode-locked through nonlinear polarization rotation. Our results tend to demonstrate, for the first time, the universality of such soliton states. Indeed, the patterns do not depend on the precise mode locking mechanism. A high power passively mode-locked fitter laser exploiting the nonlinear polarization rotation with an amplifier that delivers 10 W at the output was set up. In multi pulsing regime, we obtained experimentally a fascinating dynamic that combines two states of solitons at the same time, the harmonic mode locking of soliton crystals, when the basic pattern is a crystal. New records in the number of solitons have been obtained for the crystal state 900 pulses and 2. 500 pulses with harmonic mode locking

Повний текст джерелаCorneodesmosin (CDSN) is a protein of corneodesmosomes, the intercellular junctions specific to the cornified layer of the epidermis. Two serine- and glycine-rich domains of the protein may fold into peculiar adhesive secondary structures called "glycine" loops. In the cornified layer, progressive cleavages of CDSN and other corneodesmosomal adhesive proteins allow the desquamation process. We showed that CDSN displays homophilic adhesive properties as its expression at the surface of L fibroblast induces cell aggregation. Structure/function analysis of the protein using overlay binding assays and surface plasmon resonance evidenced that its N-terminal glycine loop domain is necessary for CDSN-CDSN interaction (KD= 11,3 æM). Molecular filtration analysis with full-length and different truncated mutants of the protein demonstrated that CDSN is able to spontaneously form large homo-oligomers in vitro also dependent of the N-terminal domain. These results show the adhesive properties of glycine loop structures and suggest a role for CDSN in reinforcing cohesion in the cornified layer. By producing and using various antibodies raised against CDSN, we localized and characterized proteolysis-induced CDSN fragments in the epidermis. The successive cleavage of its extremities and the elimination of its N-terminal glycine loop domain contribute to desquamation. We also showed the involvement of two serine proteases of the kallikrein family in the proteolysis of CDSN and other adhesive proteins of corneodesmosomes. Based on our and others published results, we proposed that a precisely controlled protease-protease inhibitor balance regulates desquamation. This work contributes to a better understanding of molecular basis of corneocyte cohesion and of desquamation physiology

Повний текст джерелаStochastic wave formulations and models are the most common tools for the assessment and forecast of sea surface conditions. Their ability to account for some of the processes encountered by waves during their evolution remains however a central question. Among other processes, the wave dissipation is for instance still poorly quantified and traditional methods for wave measurements fail to proper insight into its physics in a wide range of conditions. In this context, the work presented in this PhD aims to explore available observation techniques for their application to several quantitative aspects of the dissipation of wave energy, and particularly for short wave modulated by strong tidal currents, for short wave modulated by longer waves. This work takes advantage of the BBWAVES oceanic campaigns, especially planned to explore questions related to wave and current interactions. Data from a large variety of sensors are analyzed. The campaign provides the ground for the test of a new design of drifting buoy aimed at measuring waves in areas of strong tidal current. Its performances are verified and the description it provides of the area is explored. From simultaneous measurements, it was possible to highlight the actual inaccuracies in wave model capabilities as well as the contribution of the error contained in the atmospheric modeling over strong tidal currents to the misevaluation of sea states. This work also used an extensive dataset from a stereo video experiment in the Black Sea to investigate wave breaking in bimodal sea state conditions. These measurements have revealed the influence of long wave modulation over short wave breaking

Повний текст джерелаTo improve our knowledge of the processes and interactions which occur in Arctic between atmosphere, sea ice and ocean, an EQUIPEX funding was granted to the IAOOS project. This improvement will be reached by deploying a network of multi-instrumented buoys. For the atmospheric analyses an innovative backscattering LiDAR meeting with constraints of the project and arctic environment has been developed. An analytical model of signal to noise ratio in clear sky led to the instrumental key parameters, and numerical simulations helped in improving the system performances. An evolutive prototype has been realized within the tight planning of this EQUIPEX. The first whole equiped buoy was deployed close to the north pole in April 2014 and worked until the beginning of December 2014. A second deployment of two buoys, including a polarized version, was then realized within the N-ICE campaign from January to June 2015. These first campaigns gave first statistics of aerosols and clouds distribution in the central arctic region with an autonomous LiDAR. First results show frequent aerosols layers in mid-troposphere during spring, as well as a high occurence of very low clouds. LiDAR measurements were also used to estimate downwelling longwave and shortwave at surface. Results obtained from these first deployments and comparisons with analysis and outputs from the WRF model show a first overview of what can be expected from this network of multi-instrumented buoys in the central arctic region

Повний текст джерелаCraniosynostosis, the premature fusion of one or more cranial sutures, is a common birth defect (1/2500 live births) that results in abnormalities in skull shape and sometimes in neurological deficiencies (Wilkie, 1997; Wilkie and Morriss-Kay, 2001). Mutations in TWIST1, which encodes a class II basic helix-loop-helix (bHLH) transcription factor, cause Saethre-Chotzen syndrome, associated with coronal synostosis (El Ghouzzi et al. 1997; Howard et al. 1997). We recently discovered a new craniosynostosis gene, TCF12, which encodes a class I bHLH transcription factor. Tcf12 causes.Saethre-Chotzen syndrome and asyndromic coronal synostosis. (Sharma, Fenwick, Brockop, et al., 2013). We show that a reduction in the dosage of Twist1 and Tcf12 in mouse causes coronal synostosis, and we suggest that the Twist1 and Tcf12 form heterodimers whose dosage is critical for coronal suture development. We also demonstrate that Twist1 is required in both neural-crest and mesoderm-derived tissues for the normal coronal suture development. Moreover, we show that in the coronal suture, Twist1 excludes Notch2 thus maintaining suture patency. and we show that beta-catenin also plays a role in the maintenance of suture patency by regulating Jagged1. Finally, we identified Aggrecan, Goosecoid, Gucy1a3 and Gucy1b3 as Twist1-regulated genes that could have an impact on the normal development of the coronal suture

Повний текст джерелаThe petroleum exploration in deep water induces many challenges. Some of these problems are due to the extremely long structure that links the platform to the wellhead (risers). The depth increase makes the structure more slender, and consequently much more flexible, and its dynamical behavior may be described by an infinite dimensional system. Two associated problems are studied in this report: the positioning of the bottom structure, to connect it to the wellhead (reentry operation), and the vortex induced vibrations of these slender structures. The first part of this thesis is dedicated to the control of the reentry operation. Two different strategies of motion planning are proposed. The first one is based on a finite dimensional model obtained by a modal approach. The other one considers that the behavior of the structure is close to the behavior of the Bernoulli's historical cable equation, completed with a damping factor. The proposed approximate solutions of this PDE are directly used in the control design. Two different closed loop controls are proposed: one using a Lyapunov function, and another tracking system that uses the system inversion to calculate the tracking feedback. The second part is dedicated to the study of the structure's undergoing vortex induced vibrations (VIV) and to their control. It presents a first control strategy to reduce the VIV. This control strategy is based on a modal analysis of the system equations. The control system generates a displacement in phase opposition to the VIV, attenuating the VIV because of an anti-resonance effect. The simulation results are confirmed by experiments done on a reduced scale setup

The DAZ (Deleted in AZoospermia) gene family contains two autosomal genes, BOULE, and DAZL(DAZ like) and the Y chromosome DAZ gene. DAZ gene encoded potential RNA binding protein that is exclusively expressed in the prenatal and the postnatal germ cell lineage. In the previous study, disruption of those genes would contribute to the loss of the differentiation and migration of primordial germ cells then resulted in meiotic arrest and infertility. In this study, we set out to investigate the expression, dimerization, and interaction of these proteins by co-expression of BOULE and DAZL in mouse testis cells. In immunohistochemistry assay, BOULE is expressed in spermatocyte and DAZL is mainly expressed in spermatogonia and spermatocyte. The DAZL and BOULE protein were colocalized in mouse differential germ cells, including 4N(Leptotene stage)、2N(Spermatogonia、Primary Spermatocyte)、1N(Secondary Spermatocyte、Spermatid) cells. The results of Fluorescence Resonance Energy Transfer assay showed that DAZL in GC1, 293T, BOULE2 in TM4、293T, and BOULE1 in GC1, 293T have dimerization of each other. The BOULE1/DAZL, BOULE2/DAZL in GC1, BOULE1/DAZL in TM3, BOULE2/DAZL in TM4, BOULE1/DAZL, and BOULE1/BOULE2 in 293T have colocalized at the sites of cells. The physiological means in cell of dimerization and colocalization among DAZL, BOULE1, and BOULE2 need future investigation.

Повний текст джерелаThe synthesis of an open flame in a virtual 3D environment, remains to this day an arduous task, requiring a wise balance between realism and processing cost. In this M. Sc. thesis, we present a set of techniques for its simulation in real time while also modeling the interaction with external forces. Our goal is to minimize the cost while preserving a convincing appearance, thus facilitating integration of the techniques into existing systems without unduly affecting their performance. A velocity field is extracted from a spring-mass simulation which contributes to moving chains of particules that are used in modeling the flame shape through the configuration of a NURBS surface. In light of the importance they have on our perception of combustion, we also take care to duplicate the lighting, shadows and bloom the flame gives rise to.

Повний текст джерелаAn occupation that requires handling loads combined with large elevation of the arms is associated with the occurrence of shoulders musculoskeletal disorder. The analysis of these joint movements is essential because it helps to quantify the stress applied to the musculoskeletal structures. This thesis provides an innovative model which allows the estimation of the shoulder complex kinematics and used it to analyze the joints kinematics during lifting tasks. It is organized into three sub-objectives. The first aim is the development and validation of a kinematic model the most representative as possible of the shoulder complex anatomy while correcting soft tissue artifacts through the use of global optimization. This model included a scapulothoracic closed loop, which constrains a scapular dot contact to be coincident with thoracic gliding plane modeled by a subject-specific ellipsoid. In the validation process, the reference model used the gold standard for direct measurements of bone movements. In dynamic movements, the closed loop model developed generates barely more kinematic errors that errors obtained for the study of standard movements by existing models. The second aim is to detect and quantify the shoulder articular movements influenced by the combined effects of two risk factors: task height and load weight. The results indicate that many peaks of joint angles are influenced by the interaction of height and weight. According to the different initial and deposits heights when the weight increases, the kinematics changes are substantial, in number and magnitude. The kinematic strategies of participants are more consistent when the weight of load increase for initial height lift at hips level compared to shoulders level, and for a deposit at eye level compared to shoulders. The third aim is to investigate the magnitude and temporality of the maximum peak vertical acceleration of the box. The significant joints movements are characterized with a principal component analysis of joint angle values collected at this instant. In particular, this study highlights that elbow flexion and thoraco-humeral elevation are two correlated invariant joint movements to all lifting tasks whatever the initial and deposit height, and weight of the load. The realism of the developed shoulder model and kinematics analyzes open perspectives in occupational biomechanics and contribute to risk prevention efforts in health and safety.
Une activité professionnelle qui exige de manipuler des charges combinée à de grandes élévations des bras augmente les chances de développer un trouble musculo-squelettique aux épaules. L’analyse de ces mouvements articulaires est essentielle car elle contribue à quantifier les contraintes appliquées aux structures musculo-squelettiques. Cette thèse propose un modèle innovant qui permet l’estimation de la cinématique du complexe de l’épaule, et l’utilise ensuite afin d’analyser la cinématique de levers de charge. Elle s’organise en trois sous-objectifs. Le premier concerne le développement et la validation d’un modèle cinématique le plus représentatif possible de l’anatomie du complexe de l’épaule tout en corrigeant les artéfacts des tissus mous par une optimisation multi-segmentaire. Ce modèle avec une fermeture de boucle scapulo-thoracique, impose à un point de contact scapulaire d’être coïncident au plan de glissement thoracique modélisé par un ellipsoïde mis à l’échelle pour chaque sujet. Le modèle qui a été utilisé comme référence lors des comparaisons du processus de validation bénéficie du « gold standard » de mesures directes des mouvements osseux. Le modèle développé en boucle fermée génère à peine plus d’erreurs cinématiques lors de mouvements dynamiques que les erreurs obtenues par les modèles existants pour l’étude de mouvements standards. Le second identifie et quantifie les mouvements articulaires de l’épaule influencés par la combinaison des effets de deux facteurs de risques : les hauteurs importantes d’agencement de la tâche (hauteurs de saisie et de dépôt) et les masses de charges (6 kg, 12 kg et 18 kg). Les résultats indiquent qu’il existe de nombreux pics d’angles articulaires qui sont influencés par l’interaction des deux effets. Lorsque la masse augmente, les modifications cinématiques sont plus importantes, en nombre et en amplitude, selon les différentes hauteurs de saisies et de dépôts de la charge. Les participants varient peu leur mode opératoire pour une saisie à hauteur des hanches en comparaison des épaules, et pour un dépôt à hauteur des yeux en comparaison aux épaules avec une charge plus lourde. Un troisième s’intéresse au pic maximal d’accélération verticale de la charge dans son intensité et sa temporalité. Basée sur une analyse en composante principale des valeurs d’angles articulaires à cet instant, elle permet de caractériser les mouvements articulaires significatifs. Cette étude met notamment en évidence que la flexion du coude et l’élévation thoraco-humérale sont deux mouvements articulaires corrélés invariants à toutes les tâches de lever en hauteur quelles que soient la hauteur de dépôt et la masse de la charge. Le souci de réalisme du modèle développé et les analyses cinématiques menées ouvrent des perspectives en biomécanique occupationnelle et participent à l’effort de prévention des risques en santé et sécurité.
