Lamorlette, Aymeric. "Caractérisation macroscopique du milieu végétal pour les modèles physiques de feux de forêts". Thesis, Vandoeuvre-les-Nancy, INPL, 2008. http://www.theses.fr/2008INPL044N/document.
Texto completoThe macroscopic and gigascopic scale description of forest fires allows physical modelings of the propagation which can predict the fire evolution with a better accuracy than usually developed empirical Rothermel-like models. However, those models need fitting for their parameters which cannot be measured directly as the models equations are related to the equivalent media at the considered scale and not related to the air and the vegetal material. The equivalent media properties are related to the inner media properties, but the inner media properties knowledge does not allow directly the equivalent media properties knowledge. This work is then aiming on the vegetal medium reconstruction using fractal geometry. Geometrical parameters measurement methods used in forestry sciences are applied for the vegetal modeling validation. Numerical studies are finally done on the reconstructed structures to fit the relevant macroscopic scale parameters. Those studies also allow us to validate or invalidate the assumptions which have been done for the equivalent medium equation development. Those parameters are: the equivalent medium viscosity, the convective heat transfer coefficient and the extinction coefficient
Emmanuel, Aurélien. "Courbes d'accumulations des machines à signaux". Electronic Thesis or Diss., Orléans, 2023. http://www.theses.fr/2023ORLE1079.
Texto completoThis thesis studies a geometric computational model: signal machines. We show how to draw function graphs using-binary trees. In the world of cellular automata, we often consider particles or signals: structures that are periodic in time and space, that is, structures that move at constant speed. When several signals meet, a collision occurs, and the incoming signals can continue, disappear, or give rise to new signals, depending on the rules of the cellular automaton. Signal-machines are a computational model that takes these signals as basic building blocks. Visualized in a space-time diagram, with space on the horizontal axis and time running upwards, this model consists of calculating by drawing segments and half-lines. We draw segments upwards until two or more intersect, and then start new segments, according to predefined rules. Compared to cellular automata, signal-machines allow for the emergence of a new phenomenon: the density of signals can be arbitrarily large, even infinite, even when starting from a finite initial configuration. Such points in the space-time diagram, whose neighborhoods contain an infinity of signals, are called accumulation points.This new phenomenon allows us to define new problems geometrically. For example, what are the isolated accumulation points that can be achieved using rational initial positions and rational velocities? Can we make so the set of accumulation points is a segment? A Cantor set? In this thesis, we tackle the problem of characterizing the function graphs that can be drawn using an accumulation set. This work fits into the exploration of the computational power of signal-machines, which in turn fits into the study of the computational power of non-standard models. We show that the functions from a compact segment of the line of Real numbers whose graph coincides with the accumulation set of a signal machine are exactly the continuous functions. More generally, we show how signal machines can draw any lower semicontinuous function. We also study the question under computational constraints, with the following result: if a computable signal-machine diagram coincides with the graph of a Lipschitz-function of sufficiently small Lipschitz coefficient, then that function is the limit of a growing and computable sequence of rational step functions

Texto completoPegon, Paul. "Transport branché et structures fractales". Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLS444/document.
Texto completoThis thesis is devoted to the study of branched transport, related variational problems and fractal structures that are likely to arise. The branched transport problem consists in connecting two measures of same mass through a network minimizing a certain cost, which in our study will be proportional to mLα in order to move a mass m over a distance L. Several continuous models have been proposed to formulate this problem, and we focus on the two main static models : the Lagrangian and the Eulerian ones, with an emphasis on the first one. After setting properly the bases for these models, we establish rigorously their equivalence using a Smirnov decomposition of vector measures whose divergence is a measure. Secondly, we study a shape optimization problem related to branched transport which consists in finding the sets of unit volume which are closest to the origin in the sense of branched transport. We prove existence of a solution, described as a sublevel set of the landscape function, now standard in branched transport. The Hölder regularity of the landscape function, obtained here without a priori hypotheses on the considered solution, allows us to obtain an upper bound on the Minkowski dimension of its boundary, which is non-integer and which we conjecture to be its exact dimension. Numerical simulations, based on a variational approximation a la Modica-Mortola of the branched transport functional, have been made to support this conjecture. The last part of the thesis focuses on the landscape function, which is essential to the study of variational problems involving branched transport as it appears as a first variation of the irrigation cost. The goal is to extend its definition and fundamental properties to the case of an extended source, which we achieve in the case of networks with finite root systems, for instance if the measures have disjoint supports. We give a satisfying definition of the landscape function in that case, which satisfies the first variation property and we prove its Hölder regularity under reasonable assumptions on the measures we want to connect

Resumo: Apresentamos um método baseado na Teoria dos Fractais que permite efetuar o cálculo do grau de irregularidade em cada ponto da superfície de uma imagem topográfica. O algoritmo proposto fornece valores que são função da escala de observação, de forma a ignorar irregularidades com tamanhos muito maiores ou muito menores que o valor da escala. Dessa forma, é possível implementar duas funcionalidades: calcular os graus de irregularidade para todos os pixels de uma imagem em uma determinada escala de observação e calcular os graus de irregularidade em diversas escalas para um determinado pixel da imagem. Com a primeira funcionalidade, podemos segmentar a imagem topográfica em regiões de maior ou menor irregularidade quando observada sob uma determinada escala. Com a segunda funcionalidade, podemos estudar a variação do grau de irregularidade de um ponto da imagem quando variamos a escala de observação. Mostramos que esse estudo permite identificar os tamanhos das irregularidades que ocorrem em superfícies topográficas como, por exemplo, os tamanhos médios dos grãos e as distâncias médias entre eles. Um ambiente gráfico foi desenvolvido com a concepção de Orientação a Objetos em C++ para estudo desse algoritmo e pode ser facilmente usado para análise de outros algoritmos similares
Abstract: We describe a method based on the Theory of Fractals to calculate a measure of the degree of irregularity in each surface point of any topographic image. The proposed algorithm gives values that are dependent on the scale of observation so as to ignore irregularities which sizes are much greater or lower than the scale value. Therefore, it is possible to implement two features: calculation of the degrees of irregularity for all the pixels of an image in a given scale of observation and calculation of the degrees of irregularity in many scales of observation for a given image pixel. With the first feature we can segment the topographic image in regions of different degrees of irregularity in a given scale of observation. With the second feature we can study the variation of the degree of irregularity measured for an image pixel while we change the scale of observation. We show that the proposed method allows the identification of the sizes of irregularities that occur in topographic surfaces, such as the mean sizes of the grains
