ect of the properties of anisotropic materials and the norm ratios may be used as a criterion to represent the anisotropy degree of the properties of materials. Finally, comparison of all methods are done in order to determine similarities and differences between them. As a result of this comparison process, it is proposed that the spectral method is a non-linear decomposition method which yields non-linear orthogonal decomposed parts. For symmetric second rank and fourth rank tensors, this case is a significant innovation in decomposition procedures in the literature.

Повний текст джерелаLet K be a compact Lie group acting on the unit sphere Sⁿ by isometries. We show how an upper bound on the principal curvatures of one orbit can be used (but is not sufficient) to obtain a lower bound for the diameter of the orbit space Sⁿ/K. Then we show that there is an orbit Kp with principal curvatures bounded from above by 4√ 14.

Повний текст джерелаThe cuspidal automorphic representations of the linear group over the rationals are, in a certain sense, "the final objects" in the theory of automorphic forms. Among these, a distinguished subclass are the algebraic representations. The complexity of such a representation is measured by two numbers, its motivic weight w and its conductor N. It is then natural to try to make lists of automorphic algebraic representations with small conductor and small weight. Chenevier and his coauthors succeeded in making such lists for motivic weight up to 23 and conductor N=1. The next logical case to consider is that of conductor N=p, a single prime. The first main result of this thesis is an explicit list of all such representations with motivic weight up to 17 and conductor N=2; there are 10 of them. This result can be extended under the additional hypothesis of self-duality up to motivic weight 19. There are similar results for prime conductor up to 17 (in which the weight bound becomes lower as the conductor becomes higher). Making exhaustive lists of automorphic representations (up to a certain motivic weight and conductor) involves two steps: firstly find the "footprints" of the representations in question; secondly, prove that the list is complete. For the first step, we use the theory of Arthur, which allows for the construction of many relevant representations from classical modular forms. (First the classical object leads to a representation of an orthogonal or symplectic group, which can then be transferred to a general linear group.) For the second step, we use an analytic method known as the explicit formula of Riemann-Weil-Mestre. For small weight and conductor, the lower bound provided by the constructive method coincides with the upper bound provided by the explicit formula, and hence one has obtained a complete list of automorphic representations. Along Arthur's theory, the relevant transfer for this thesis is that of split orthogonal groups SO₂ₙ₊₁ to GL₂ₙ. Since the goal is to construct representations of GL₂ₙ with prime conductor, a precise understanding of the representations of SO₂ₙ₊₁ with prime conductor is required. This is where the local part of the thesis comes in. We are able to classify the irreducible, admissible, tempered representations of SO₂ₙ₊₁(F) of prime conductor, where F is a p-adic field. We are furthermore able to characterize such representations according to a conjecture of Gross (which is then proven in the given case). This is the second main result of this thesis

Повний текст джерелаLa seconde est relative à la réduction du nombre de simulations demandé par la méthode Monte-Carlo classique de propagation d'incertitude. La technique utilisée ici est basée sur une représentation d'une sortie de modèle incertaine comme un développement de polynômes orthonormaux de variables d'entrées. Un autre point clé dans la modélisation intégrée d'impacts est de développer des stratégies de réduction des émissions en calculant des matrices de transfert sur plusieurs années de simulation. Une méthode efficace de calcul de ces matrices a été ainsi développée, notamment en définissant des scénarios "chimiquement" représentatifs.
L'ensemble de ces méthodes a été appliqué au modèle POLAIR3D, modèle de Chimie-Transport développé dans le cadre de cette thèse.

Multimedia database systems are becoming increasingly important with the advent of broadband networks, high-power PC’s, audio/video compression standards, and many applications, such as digital libraries and trademark and copyright databases. In this study, an image retrieval system using orthogonal wavelet representation is proposed. In the proposed system, a color image is represented in the RGB color coordinate system so that three component images can be extracted from the color image. Based on the frequency coefficients, each component image is segmented into 10 bands, i.e., one low frequency band and nine high frequency bands, by 3-level orthogonal wavelet representation first, and the coefficients of the low frequency band are extracted as the image feature and the coefficients of the nine high frequency bands are extracted as the image texture features. In the image retrieval stage, the distance measure between a query image and a target image in the image database system will be the weighted sum of squared errors of two sets of coefficients of the image texture features extracted from nine high frequency bands. To obtain the better retrieval precision, different high frequency coefficients with different importances in orthogonal wavelet representation will receive different weights. Based on the experimental results obtained in this study, the performance of the proposed system is better than that of two comparison systems. This shows the feasibility of the proposed system.
