Повний текст джерелаToday, the digital models are usually used in the world of research, but also in industry, health, finance, etc.… The quality of the results will always be connected to the accuracy with which the engineer is able of formalizing the physical phenomena. More specifically in the biomechanical modelling, working with a high number of parameters, making very complicated the standardization of the models. This thesis has an approach of improvement in the quality of the digital models of the human skull through several studies having for aim the analysis of the morphological parameters of the skull and their use for the personalization of a morpho-mechanical model.The method of scan by micro-tomography was used to scan more than 360 samples taken from 10 skulls, and then mechanical tests of compression in quasi-statics and dynamics were led on a part of these samples. The results we obtained allowed us to develop a card of evolution of a number of morphological parameters of the skull based on a polynomial model. A statistical comparative study allowed to highlight the existing links between the morphology and the mechanical behaviour of these samples. Finally, the connection of these two studies allowed to propose a customizable morpho-mechanical model, and to validate it for various finite elements simulations on bones samples and on complete human skull

Повний текст джерелаTwo prophylactic vaccines have demonstrated to prevent infections with the human papillomavirus (HPV). Thus, they have been in the market for the last four years, or so. The three main objectives of the present project were: i) to study in-silico the immunogenicity of one of these vaccines (Gardasil®); ii) to study in-silico the natural history of an HPV infection, and iii) to assess in-silico the potential of the following therapeutic hypothesis : the intramuscular administration of Gardasil® to patients already suffering from a recurrent respiratory papillomatosis would result in a better prognosis thanks to the fact that the HPV-specific immunoglobulins that would bathe the affected tissue would impede the virus to complete its life cycle and, therefore, the disease to progress. The main conclusions are: i) according to our simulations, the minimum serum IgG titer required for hampering the progression of a recurrent respiratory papillomatosis would be 200 mMU/mL ; ii) in order to keep, within a time window of ten years, the anti-HPV IgG titer over the just-mentioned therapeutic-effect threshold, the biggest possible fraction of time and through the administration of the smallest possible number of booster doses, it would be necessary, according to our simulations, to adopt the following vaccination schedule: the basic three doses (at months 0, 2 and 6), followed by three successive booster doses, every six months, until reaching the 24th month, followed by a late final booster dose, 18 months later. iii) incidentally, it would seem to be inappropriate, according to our simulations, to modify the original initial vaccination schedule (at months 0, 2 and 6)

Повний текст джерелаRoad safety is a major issue of public health and personal safety. According to the World Health Organization (WHO), nearly 1.2 million people die each year worldwide due to road accidents (2015). According to accident data, 36.7% of serious injuries are caused by thoracic injuries (Page et al., 2012). The aim of biomechanics in passive safety is to improve our understanding of the human body in order to build better tools for assessing the risk of injury.Numerical human body models are used to virtually simulate the conditions of an accident. Today, they are increasingly used by car manufacturers and equipment manufacturers to better understand injury mechanisms. However, they exist only in few sizes and do not take into account the morphological variations observed in the population.3D medical imaging gives access to the geometries of the different anatomical structures that make up the human body. Today, hospitals are full of 3D images covering a very large part of the population in terms of age, body size and sex.The overall objective of this thesis is to statistically model the 3D geometry of the rib cage from medical images in order to personalize a numerical human body model to simulate car crash conditions.The first objective is to develop a segmentation process based on CT-scans in order to obtain geometric data adapted to the construction of a statistical model of shape of the rib cage.The second objective is to build a statistical model of the shape of the rib cage, taking into account its articulated structure.The third objective is to use the statistical model of the rib cage to deform a numerical human body model, in order to study the influence of certain parameters on the risk of injury
Gavant, Fabien. "Contribution à des architectures de stabilisation d'images basées sur la perception visuelle et la physiologie du tremblement humain." Thesis, Grenoble, 2012. http://www.theses.fr/2012GRENT061/document.
Повний текст джерелаWith the integration of cameras in mobile devices, their democratization and the reduction of the imager’s size, the optical system dimensions and the pixels miniaturization, the photos become more and more subject to motion blur due to the hand tremor. In addition, the requirements in terms of image quality become higher and higher. Hence, in order to reduce this blur, several image stabilization systems have been developed. Nevertheless, they cannot guarantee the sharpness quality of resulting images and in some cases, they show integration difficulties. In order to overcome these limitations, the research work presented in this thesis proposes, first of all, a physiological tremor model that aims to simulate realistic camera shake and secondly, presents a study on visual perception of blur. This study enables the development of a quality metric. Finally, stabilization algorithms and architectures exploiting these new tools are presented. These new architectures reduce the number of external components and ensure sharp stabilized images

Повний текст джерелаIn this thesis, we present the evolutions made to the Discontinuous Galerkin solver Teta-CLAC – resulting from the IRMA-AxesSim collaboration – during the HOROCH project (2015-2018). This solver allows to solve the Maxwell equations in 3D and in parallel on a large amount of OpenCL accelerators. The goal of the HOROCH project was to perform large-scale simulations on a complete digital human body model. This model is composed of 24 million hexahedral cells in order to perform calculations in the frequency band of connected objects going from 1 to 3 GHz (Bluetooth). The applications are numerous: telephony and accessories, sport (connected shirts), medicine (probes: capsules, patches), etc. The changes thus made include, among others: optimization of OpenCL kernels for CPUs in order to make the best use of hybrid architectures; StarPU runtime experimentation; the design of an integration scheme using local time steps; and many optimizations allowing the solver to process simulations of several millions of cells

Повний текст джерелаAutomakers are lawfully required to achieve a minimum level of security which is checked during standardized crash tests. This results in a limited number of scenarios, which do not take individual specificities into account. This dissertation evaluates real human behaviour during the pre-crash phase, by means of a driving simulator. The experiment, integrating an unavoidable accident, studied the behaviour of 76 drivers, of which 40 drivers on a dynamic simulator. Concerning this group, 43 acquisition channels dedicated to drivers were added. From the results, one can retain that the crash can be predicted for half of the drivers through the observation of their behaviour and their interaction with the car. Due to swerving manoeuvres, 25% of the drivers have their forearm just in front of the steering wheel at the time of crash. This situation may compromise the efficiency of the airbags, that is verified experimentally on a static bench, by the deployment of airbags in front of a Hybrid III-50% dummy. The throwing of the arm causes an impact of 120 g to the head. In a second stage, the integration of left upper limbs from PMHS reveals that the situation is likely to generate fractures in the forearm. A numerical model has been designed to estimate the consequences of the atypical position during a frontal crash at 50km/h. The head acceleration reaches 270 g, synonymous with high lesion risks. Finally, a technological modification of the airbags is proposed to reduce this risk. The assumption is made that the use of remote sensors technologies can allow an early detection of the crash and therefore slower triggering of airbags. Tested experimentally and then numerically, this technical evolution reduces the violence of the impact to respect the injury criteria

Повний текст джерелаConsiderable research and development efforts are currently focused on automated vehicles that could free drivers from driving tasks and allow them to perform new activities (e.g. working, sleeping). Such activities would benefit from new seating configurations. However, even if a high level of safety is expected for these future vehicles, accidents will continue to occur. Current protective devices are designed for a driving position. They may require modifications to maintain the current level of protection for new occupant positions. This thesis aims to identify the risks and opportunities in terms of occupant protection associated with new positions that could appear with automated vehicles. The analyses used digital human models for applied traffic safety which have proven to be a relevant risk assessment tool. Particular attention was paid to assessing the validity of the models after repositioning. The work provided a better understanding of the restraint mechanisms in reclined configurations during a frontal impact. These positions appear to be critical with a difficult restraint of the pelvis or loading of the lumbar spine depending on the seat angle. The occupant response was also significantly affected by the initial position of the pelvis. These results can be used to help design and evaluate new restraint systems. In order to better understand the comfortable position in these reclined configurations, an experimental study was carried out using a multi-adjustable seat. These experiments enabled, on the one hand, to identify the comfort seat configurations, and on the other hand to establish the relationships between these seat configurations and the position of the internal skeleton and in particular for the pelvis. These results can in particular help the positioning of occupants during physical or digital tests. Overall, this work shows the strong interaction between comfort and safety for the design of new passenger cars
Guillot, Olivier. "Maillage multirésolution de surfaces : modélisation et maillage de formes humaines 3D." La Rochelle, 2008. http://www.theses.fr/2008LAROS232.
Повний текст джерелаIn this thesis, we developped a surface subdivision that handles different kind of natural discontinuities of surfaces (darts, corners, creases and bounds) and the irregularities of the mesh that represents it. The aim of such a subdivision is to create limit surfaces that keep the natural discontinuities in order to enhance the quality of the multiresolution analysis based on that subdivision. We use the square root 3-subdivision because the resulting meshes grow slower. The multiresolution analysis by wavelets of a mesh of surface split the low frequencies and the higher ones, in order to obtain an approximation of the mesh and "details". Details can be truncated without creating great losses in the result of the synthesis. This property permits data compression of the details. Because the wavelet function is based on our square root 3-subdivision it handles natural discontinuities of the surfaces. This gives even smaller details for meshes with sharp edges. In order to analyse a mesh n times, this mesh must have a topology compatible with n subdivisions. If the surface contains discontinuities, n should be even. We built software tools in order to create a remeshing method that generates meshes compatible with those topologies. All this features are available in MEFP3C
