Sciannandrone, Daniele. « Acceleration and higher order schemes of a characteristic solver for the solution of the neutron transport equation in 3D axial geometries ». Thesis, Paris 11, 2015. http://www.theses.fr/2015PA112171/document.
Texte intégralThe topic of our research is the application of the Method of Long Characteristics (MOC) to solve the Neutron Transport Equation in three-dimensional axial geometries. The strength of the MOC is in its precision and versatility. As a drawback, it requires a large amount of computational resources. This problem is even more severe in three-dimensional geometries, for which unknowns reach the order of tens of billions for assembly-level calculations.The first part of the research has dealt with the development of optimized tracking and reconstruction techniques which take advantage of the regularities of three-dimensional axial geometries. These methods have allowed a strong reduction of the memory requirements and a reduction of the execution time of the MOC calculation.The convergence of the iterative scheme has been accelerated with a lower-order transport operator (DPN) which is used for the initialization of the solution and for solving the synthetic problem during MOC iterations.The algorithms for the construction and solution of the MOC and DPN operators have been accelerated by using shared-memory parallel paradigms which are more suitable for standard desktop working stations. An important part of this research has been devoted to the implementation of scheduling techniques to improve the parallel efficiency.The convergence of the angular quadrature formula for three-dimensional cases is also studied. Some of these formulas take advantage of the reduced computational costs of the treatment of planar directions and the vertical direction to speed up the algorithm.The verification of the MOC solver has been done by comparing results with continuous-in-energy Monte Carlo calculations. For this purpose a coupling of the 3D MOC solver with the Subgroup method is proposed to take into account the effects of cross sections resonances. The full calculation of a FBR assembly requires about 2 hours of execution time with differences of few PCM with respect to the reference results.We also propose a higher order scheme of the MOC solver based on an axial polynomial expansion of the unknown within each mesh. This method allows the reduction of the meshes (and unknowns) by keeping the same precision.All the methods developed in this thesis have been implemented in the APOLLO3 version of the neutron transport solver TDT

Texte intégralThis thesis focuses on a specific pathology affecting the abdominal section of the aorta, known as abdominal aortic aneurysm (AAA). An aneurysm involves a persistent and localized weakening of the vessel wall, leading to enlargements and bulges, causing recirculation and turbulence of blood flow.Our thesis outlines a methodology for geometric modeling of abdominal aneurysms. The process involves acquiring CT images, reconstructing the aorta 3D geometry, and isolating the aneurysm. The modeling phase begins by identifying and approximating the centerline of the aortic vessel using B-spline functions. The aortic wall is then partitioned and profiled using Fourier series.To evaluate its effectiveness, the developed technique is applied to a dataset of CT scans from patients. Reconstructions obtained from the scans are also presented as examples to detail each step of the procedure. In addition, a quantitative evaluation and rationale behind modeling parameters are explained. Then, as a first application, the modeling is integrated into a registration process for clinical diagnosis and follow-up.The geometrical modeling procedure developed is used in a pipeline for hemodynamic simulations and risk assessment, employing a reduced-order modeling approach to construct a reduced solution space. Simulations, utilizing parameterized geometries, are conducted under realistic conditions, and risk indicators are computed and linked to the geometrical representation using Radial Basis Functions interpolant. Finally, predictions on risk indicators are obtained for an unknown geometry. The results, despite being promising, can be further improved by appropriately augmenting the initial dataset.To address the aforementioned scarcity of clinical data, we devised an automated workflow for generating synthetic geometries. This approach allows for the identification of relevant geometry parameters and involves machine learning to generate a virtual patient population consistent with the original data. In addition to improving the predictive capability of reduced models, the method can also be applied prospectively for in-silico trials and studies involving virtual patient populations

This research aimed to investigate how the GeoGebra software can provide the development of creative, intuitive and visual abilities in the statement of theorems of synthetic geometry. The research was carried out with five students of the first year of high school in a state school of Rio Grande do Sul. This is a qualitative research carried out in the computer lab; data collection was obtained through the records of the constructions carried out by students and analyzed existing protocols in the software itself. The investigative activities, developed in workshop mode, consisted of four specific theorems of plane geometry, chosen at random and feasible to be offered to students of elementary school. The research results showed that the activities provided through the GeoGebra software, the development of creativity, the use of intuitive thinking and visualization as a way of analyzing the operation of ideas in the formulation of conjectures, which contributed to the construction of theorems, providing meaningful learning. Also, it indicates synthetic geometry as a way to perform logical statements of theorems, developing reasoning skills and justifications. In turn, the results showed that the use of GeoGebra software, used in construction, was key to achieving the goals in the research.

Texte intégralThe herein thesis represents a complex study of photosensitive azopolysiloxanes and rejoins both theoretical and experimental techniques. The theme revolves around the azopolymer’s mass transport phenomenon induced by the photoisomerization of azobenzenes. Trans- to cis conversion of azobenzene and its derivatives is a reversible light actuated process that enables the rearrangement of surrounding matter at nano and micro level. This property is exploited to fabricate surface relief gratings (SRG) with certain geometrical features. The present studies are directed to comprehension of this complex mechanism, subject to great controversial among different research groups. The parameters that control the process are addressed and analyzed. Experimental study comprises the synthesis and characterization of four azopolysiloxanes which are then analyzed for the capacity to obtain SRG. Photochromic behaviour is evaluated through irradiation experiments at different light intensity, in the presence or absence of an assistance light that supposedly intensifies isomerization. Computer simulation focuses on diffusion of the molecules in the system: one azobenzene – like molecule (molecular motor) diluted in the host medium. Molecular modeling calculations are performed for motors with different lengths and with various isomerization times (fast or slow isomerization) in order to define the relation between these parameters and diffusion. Providing experimental and theoretical info on azopolymers is part of the SRG formation insight

Texte intégralIn the present work, we tried to investigate the conics in the synthetic, analytical and projective contexts, as well as to know some applications and properties of these curves. In the synthetic approach, it was emphasized a lithe of the historical aspects, the works made by Apollonius and Dandelin, a characterization for tangent and normal lines and re ecting properties. In the analytical approach, the Cartesian, polar and parametric equations were described, as well as the applications in the Kepler Laws. In the projective approach, the concepts of projective plane, projective point, projective line and projective applications were used to give meaning to the conic in the projective universe, in addition the Theorews of Pascal and Brianchon were demonstrated.
No presente trabalho, procurou-se investigar as cônicas nos contextos sintético, analítico e projetivo, bem como conhecer algumas aplicações e propriedades dessas curvas. Na abordagem sintética, foram enfatizados um pouco do aspecto histórico, os trabalhos feitos por Apolônio e Dandelin, uma caracterização para retas tangentes e normais e as propriedades refletoras. Na abordagem analítica, foram descritas as equações cartesianas, polares e paramétricas, como também as aplicações nas Leis de Kepler. Na abordagem projetiva, foram trabalhados os conceitos de plano projetivo, ponto projetivo, reta projetiva e aplicações projetivas para dar significado as cônicas no universo projetivo, além disso foram demonstrados os teoremas de Pascal e Brianchon.
