Full textThe research work carried out in this thesis is part of a context of vehicle electrification in response to environmental concerns. This thesis focuses on the modeling and optimization of commutator machines used in powertrains of small electric vehicles. This kind of machines represents an alternate solution due to their competitiveness, robustness and reliability mainly due to the absence of power electronics. Nevertheless, they require compensation windings and commutation poles to improve their performances. Commutator power supply makes it necessary to take into account electrical dynamics in numerical magnetic modeling by finite elements. That is why, it is crucial to develop a model allowing a strong coupling in the sense of the variational formulation, of magnetic problem, external electrical circuit and finally current flow problem at the commutator interface. In this context, the use of a modeling opensource platform ONELAB has led to the development of an original model that performs projection of physical properties and sources on a fixed mesh. This method avoids remeshing during iterative processes such as geometric optimization or movement modeling. This method has led to the dynamic coupling of the magnetic problem and the external electrical circuit to the current flow formulation at the commutator interface as well as to prospects for multi-physical simulations at this interface. Finally, the choice of an optimization algorithm adapted to the numerical models (black box with a high evaluation cost) allowed the development of a tool for the design of commutator machines adapted to many topologies in order to fulfill industrial requirements

Full textCell ability to sense mechanical properties of their microenvironment is crucial for tissue homeostasis which means their capacity to maintain mechanical integrity as they are submitted to external forces.Integrins have been highlighted as mechanotransducers able to form micro-scale structures called focal adhesion sites which mechanically link cells to the extracellular matrix by recruiting various adaptors. Both b1 and b3 integrins have been identified as the principal actors of tensional homeostasis. However as the resulting mechanotransduction processes are intrinsically dynamic, the respective and cooperative roles b1 and b3 integrins need to be addressed over time and space.In the present work, coupling time-resolved traction force microscopy and genetics approaches, we investigated the respective role of b1 and b3 integrins in active force generation at the single cell level. Our findings show that b1 integrins has an essential role in generation of cellular traction forces, b1 integrin-generated force is negatively regulated by b3 integrins which impacts the redistribution of b1 integrin containing adhesion through its ability to bind to talin and kindlin, b3 integrin supports min-scale temporal regulation of cellular contractile activity generated by b1 integrin. Finally, cell mechanical equilibrium relies on the ability of cells to maintain a fixed contractile moment.I also participated in two others studies in the framework of collaborations in which I used the traction force microscopy as a diagnostic tool to observe the effect of contractile forces in the formation of the aortic lumen and the formation of proplatelets. I was able to confirm that the protein amotL2 connecting the contractile fibers to VE-cadherin, is involved in intercellular forces necessary for the formation of the aortic lumen. And in a second collaboration, where I found by using traction force microscopy that the contractility of megakaryocytes via its actomyosin system, is necessary for the formation proplatelets
Duvernoy, Marie-Cécilia. "Mécanique de croissance d'une micro-colonie bactérienne." Thesis, Université Grenoble Alpes (ComUE), 2015. http://www.theses.fr/2015GREAY074/document.
Full textIn this work, we propose a framework to understand the morphogenesis of two-dimensional microcolonies. In particular, we have explored how growth and adhesion of individual cells compete during microcolony extension. We have shown (i) that isolated cells display an asymmetry in their adhesion, which is higher at the old pole, (ii) that bacterial elongation can result in pushing forces inside the colony. Since the combination of these two effects is expected to produce mechanical stress at the scale of the microcolony, we have developed a method to measure the resulting adhesion forces using deformable substrates. We have demonstrated that focal adhesions are dynamically established and ruptured, with a bias towards the old poles. We have also probed the role of adhesion in the shape of the colony. We have shown that polar adhesion drives the transition from a linear to a two-dimensional growth after the first division. At larger colony sizes, the level of adhesion continues to correlate with the global shape of the colony. Finally, adhesion is involved in the transition from a two-dimensional to a three-dimensional colony. Taken together, our results suggest that the expression of adhesins and their location at the surface of the cells could be levers by which bacteria actively modulate the shape of the group in which they reside
