Full textTechnological advances known as part of the integration of power systems bring different physical problems and inevitably introduce linkages between them. The realization of models is very expensive, hence the need for virtual prototyping. This involves engineering, design and multi multi physical scale. In this context, it is necessary to control a particular temperature during the stages of virtual prototyping. The numerical methods can make forecasts heat through the resolution of a very large number of equations. But these costly methods fail to address the optimization of a thermal-electric coupling as in the case of power modules. The macro modeling without mesh is then an interesting alternative for thermal analyses. These analytical models are easy to combine with electrical and mechanical models, to make simulations multi physical fast. Our work is directly in this context. The main idea is the application of "Representation Diffusive" modeling thermal modules and components for power. This approach is effective for the generation of thermal analytical models easy to combine with electric models. From a single transient simulation type finite element (MEF) or finite differences (DF), or an appropriate measure on the system, built on a model thermal representation of state-type input-output compatible with simulators "Circuit". The major advantage of this approach lies in simplifying the thermal model as the cartographic knowledge of the solution is not required. In a first step, a thermal model of a bullet IGBT on a substrate has been developed. The transient response of the maximum temperature of the structure (end of the canal) is evaluated and compared to an extent and this for different pulses power dissipated. An analytical model of a self heating VDMOSFET is built from a single 2D simulation electro thermal type finite element. The comparison of results between the analytical model and simulation elements purposes is satisfactory. Finally, we treat thermal interactions between chips within the power modules. An experimental module allows the necessary steps to build a global model, and a comparison of results

Full textOur aim is concentrated around building ego-centric topometric maps represented as a graph of keyframe nodes which can be efficiently used by autonomous agents. The keyframe nodes which combines a spherical image and a depth map (augmented visual sphere) synthesises information collected in a local area of space by an embedded acquisition system. The representation of the global environment consists of a collection of augmented visual spheres that provide the necessary coverage of an operational area. A "pose" graph that links these spheres together in six degrees of freedom, also defines the domain potentially exploitable for navigation tasks in real time. As part of this research, an approach to map-based representation has been proposed by considering the following issues : how to robustly apply visual odometry by making the most of both photometric and ; geometric information available from our augmented spherical database ; how to determine the quantity and optimal placement of these augmented spheres to cover an environment completely ; how tomodel sensor uncertainties and update the dense infomation of the augmented spheres ; how to compactly represent the information contained in the augmented sphere to ensure robustness, accuracy and stability along an explored trajectory by making use of saliency maps

Full textIntroduced in microbiology in 2005, pangenome approaches aim to compile the entire genomic diversity of a species. In these studies, we generally distinguish within the pangenome, the core genome, i.e. the set of gene families where gene representatives are present in all organisms; and on the other hand, the accessory genome which corresponds to genes specific to certain organisms only. However, we noticed that the concept of the core genome is limiting with a large number of organisms because genes, although functionally essentials, may be absent from some genomes. To deal with this issue, almost all studies use an arbitrary threshold of presence (generally 95%) to define a soft core genome. Moreover, this dichotomy between the core and accessory genome does not account for the many ranges of frequencies at which genes appear in a pangenome. The main goal of this thesis work is to introduce a statistical approach based on a multivariate Bernoulli mixture model coupled with a hidden Markov random field to partition the pangenome in order to be resilient to gene absences and to better distinguish the gene presence/absence patterns. In parallel, several data structures based on pangenome graphs have been developed in recent years. Indeed, exploiting all the information available in genomes and not just the presence of isolated genes is crucial to highlight genomic organization and particularly the regions of genomic plasticity in species. This approach is intended to be the missing link between these new graphic approaches at the sequence scale and the original approaches in isolated gene families. To achieve this, this thesis work therefore focuses on the definition, statistical partitioning and exploitation of a graph of a pangenome as a compact representation of the diversity of the genomic repertoire of prokaryotic species. Finally, this graph is then used to analyze the pangenomic diversity of 439 prokaryotic species

Full textLet U be a compact Lie group and K a closed subgroup such that the quotient space U/K is a compact symmetric space. We apply geometric quantization to the cotangent bundle of U/K, for which we have two natural choices for a polarization: the vertical polarization and the holomorphic polarization. Geometric quantization then gives us two Hilbert spaces, one a space of functions on U/K and the other a space of holomorphic functions on the cotangent bundle which can be identifies with the complexification U^C/K^C. We obtain the BKS pairing between these two spaces, which gives us (in theory) the BKS transform between these two spaces. In order to study whether this BKS transform is unitary, we use in particular the theory of unitary representations of compact Lie groups, which allows us to reduce this question to a question that involves only spherical functions. Uniqueness of spherical functions for a given representation then simplifies the problem enormously. Our method can be applied to compact Lie groups by considering a compact Lie group K as a compact symmetric space: it suffices to take U=K x K and K =diag(K). By using Kirillov's character formula our method allows us to give yet another proof that the BKS transform for compact Lie groups is unitary (our proof is a variation of the proof given by Huebschmann). Our method also allows us to show that the BKS transform is not unitary for an arbitrary compact symmetric space. An explicit counter example is the 5-sphere S^5 seen as symmetric space by taking S^5=SO(6)/SO(5). On the other hand, introducing the parameter hbar as suggested by physics, we show that the BKS transform is asymptotically unitary for all compact symmetric spaces in the limit hbar --> 0

Full textIn this thesis, we study the combinatorial and operator algebraic properties of certain free compact quantum groups. We prove in chapter 2 that the duals of the quantum reflexion groups have, in most cases, the Haagerup property. In chapter 3, we describe the fusion rules of the free wreath product of a discrete group by the quantum permutation group. To do this, we describe the interrwinner spaces berween certain “basic” corepresentations of these free wreath products in terms of non-crossing partitions decorated by the elements of the group . This provides a whole new class of compact quantum groups whose fusions rules are explicitly computed. We give several applications of this result.We prove that, in most cases, the reduced C*-algebras associates with these free wreath products are simple with unique trace. We also prove that the associated II 1 factors are full. To conclude, we extend the result of chapter 2 to the free wreath products of finite groups by the quantum permutation group

Full textThe social intelligence, one of the three intelligence's categories denoted by thorndike in 1920 is this dissertation's subject. Social intelligence means the actions towards others and the behaviors in the interpersonals relationships. Social intelligence has been mesured through two of its components: social self esteem and interpersonal problemsolving. The question is to know the influence of the father on his children's social intelligence. Father's influence will be envisaged through his "educative presence" perceived by his children. The framework used here is the social behaviorism, particularly bandura's social learn theory and the social interactions premises. Relationship between father's "educative presence" and interpersonal problem-solving is positive. Relantionship between father's "educative presence" and social self esteem is more complex
