Full textThe objective of the research is to improve the knowledge of dissipative effects and to establish models for predicting the dynamic behavior of mechanical Systems equipped with localized non-linearities or subjected to variable forcing frequency. The manuscript contains two parts. Part I. Hysteresis operator : An original hysteresis operator is proposed. It is employed for modelling localized non-linearities and in particular the load deflection loop of mounts used in vibration isolation. First, an overview on viscous and dry friction models and on existing hysteresis operator models is perfomed. Then, the proposed model is described in details, a particular attention is paid on its mathematical formulation. The applications concern an elastomer and a dry friction mounts. Finally the measured harmony and transient responses of a flexible structure equipped with such mounts permit the validation of the proposed model. Part II. Metric phenomenon : It is shown that a variable forcing frequency applied to a mechanical System creates a damping effect. Broadly speaking, the parameters of the equations of the motion are modified when the motion deforms the reference frame. First, using the concept of the special relativity and an additional axis representing the forcing frequency, it is shown that each degree of freedom of a mechanical System has its proper time. The metric is experimentally identified. The application concerns a one-degree of freedom System subjected to variable harmony excitation. The model is experimentally validated. Then, the concept of the general relativity is used for avoiding the experimental identification of the metric, which depends on the co-ordinates of the Riemannian space. The solution of the variational problem of the metric gives the equations of the geodesy, which are the equations of the motion. The proposed method is experimentally validated using three different mechanical Systems (one-DOF, multi-DOF and continuous Systems)

Full textThe Wasserstein space is the space of probability measures over a given domain endowed with the quadratic Wasserstein distance. In this work, we study variational problems where the unknowns are mappings valued in the Wasserstein space. When the source space is a segment, i.e. when the unknowns are curves valued in the Wasserstein space, we are interested in models where, in addition to the action of the curves, there are some terms which penalize congested configurations. We develop techniques to extract regularity from the minimizers thanks to the interplay between optimal density evolution (minimization of the action) and penalization of congestion, and we apply them to the study of Mean Field Games and the variational formulation of the Euler equations. When the source space is no longer a segment but a domain of a Euclidean space, we consider only the Dirichlet problem, i.e. the minimization of the action (which can be called the Dirichlet energy) among mappings sharing a fixed value on the boundary of the source space. The solutions are called harmonic mappings valued in the Wasserstein space. We prove that the different definitions of the Dirichlet energy in the literature turn out to be equivalent; that the Dirichlet problem is well-posed under mild assumptions; that the superposition principle fails if the source space is no longer a segment; that a sort of maximum principle holds; and we provide a numerical method to compute these harmonic mappings

Full textWe extend the theory of tent spaces from Euclidean spaces to various types of metric measure spaces. For doubling spaces we show that the usual `global' theory remains valid, and for `non-uniformly locally doubling' spaces (including R^n with the Gaussian measure) we establish a satisfactory local theory. In the doubling context we show that Hardy–Littlewood–Sobolev-type embeddings hold in the scale of weighted tent spaces, and in the special case of unbounded AD-regular metric measure spaces we identify the real interpolants (the `Z-spaces') of weighted tent spaces.Weighted tent spaces and Z-spaces on R^n are used to construct Hardy–Sobolev and Besov spaces adapted to perturbed Dirac operators. These spaces play a key role in the classification of solutions to first-order Cauchy–Riemann systems (or equivalently, the classification of conormal gradients of solutions to second-order elliptic systems) within weighted tent spaces and Z-spaces. We establish this classification, and as a corollary we obtain a useful characterisation of well-posedness of Regularity and Neumann problems for second-order complex-coefficient elliptic systems with boundary data in Hardy--Sobolev and Besov spaces of order s in (-1,0)

Full textOur goal is to develop a framework allowing the definition of source code transformations based on dynamic metrics.This framework be integrated to the MAQAO tool suite developed at the UVSQ / ECR.We present a set of source-to-source transformations guidable by the end user and by the dynamic metrics coming from the various MAQAO tools in order to work at source and binary levels.This framework can also be used as a pre-processor to simplify the development by enabling to perform cleanly and automatically some simple but time-consuming and error-prone transformations (i.e .: loop/function specialization, ...)
