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.
The 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

This 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

Ciobotarescu, Simona. "Synthesis, molecular modeling and photochromic behaviour of polysiloxanes containing azo-groups with different geometries." Thesis, Angers, 2020. http://bu.univ-angers.fr/Contact.
The 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

In this work a gate sizing tool is developed using problem optimization techniques based on Geometric Programming. To size the gates in a circuit, first, the logic gates are modeled using the RC switch model and the delay is calculated using Elmore delay model, which produces posynomial functions, enabling the problem solution by geometric programming. For each port a scale factor is set that multiplies the transistors width, where the variables that represent the scale factors are the problem optimization variables. Gate sizing developed in this work is for CMOS circuits and is configurable to several CMOS manufacturing technologies. Moreover, the optimization can be done in two ways, minimizing delay restricting area or by minimizing area restricting circuit delay. In this work, gate sizing tests were made considers two different technologies, 45nm and 350nm, where the results were compared with the sizing available in a typical standard-cell library. For 45nm technology, the gate sizing proposed in this work considering delay minimization, obtained a reduction, in average, of 21% in delay, keeping the same area and power values of the sizing provided by standard-cells library. After, it was made an area optimization restricting delay to the value found at delay minimization. This optimization allowed an average reduction of 28.2% in area and 27.3% in power consumption, compared to the values obtained by delay minimization. This shows that by making the minimization of delay followed by the minimization of area, the smallest delay and the smallest area for the circuit is found, where an optimization does not prevent the other. The same optimizations were made for 350nm technology, where gate sizing considering delay minimization achieved a reduction, on average, of 4.5% in delay, keeping power consumption and area values similar to the values given using the sizes found in a commercial standard-cell library in 350nm. The area minimization, restricting delay to the value given by delay minimization, was able to reduce the area in 29.9% and power at 28.5%, on average.

This thesis mainly addresses three major aspects such as systematization and structural analysis, geometric and kinematic formulation and control strategies. The first part of the thesis is dedicated to the development of a systematization approach for reconfigurable mechanisms with respect to their structural parameters such as mobility, connectivity, redundancy and number of overconstraints. These parameters help us to understand the mechanism and to systematize it according to type of motion, whether the mechanism is overconstrained or non-overconstraint, redundant or non-redundant, with/without internal mobilites, etc. To resolve the practical problems of modeling, control, simulation and development of the robot, the structural parameters are required. Various types of singularities are also systematized and analyzed by taking into account the structural parameters. Further to know the relative location of robot links, we need to compute the geometric model. We use Travel Coordinate System method to determine the position and orientation of links at each instant. To find out the linear and angular velocities of links, we need to formulate the kinematic equations for the robot under consideration. The control part is dedicated to the development of trajectory generation and control strategies, based on actuation redundancy. The challenging task is to develop an advanced control law in order to synchronize several actuators to have a smooth transition from one assembly mode to another without causing wear and tear to the robot. Choice of actuated joints also plays a vital role in ensuring high performance and controllability of the mechanism when crossing singular configurations. In this thesis we focus on the 8-bar single loop mechanism to illustrate the developments achieved in the three parts mentioned above. It has been shown that, this mechanism exhibits an interesting capacity to reconfigure. It has two degrees of mobility in a general configuration but needs at least five motors to be fully controlled in all singular configurations

Nos dias atuais, os componentes eletrônicos estão cada vez mais potentes e com mais dispositivos integrados e há a necessidade de uma dissipação térmica mais eficiente. Os atuais ventiladores e dissipadores de calor usando ar como fluido de trabalho estão ficando obsoletos. Por este motivo, torna-se necessário o desenvolvimento de um sistema mais eficiente. Existem três técnicas principais em estudo nesta área: resfriamento líquido, trocadores de calor compostos por microcanais e jatos sintéticos como transmissores de quantidade de movimento ao fluido. Entretanto, a análise em pequena escala encontra limitações experimentais de modo que uma abordagem por Dinamica de Fluidos Computacional (Computational Fluid Dynamics – CFD) é mais recomendável para caracterizar e validar o desempenho dos jatos sintéticos. O objetivo principal deste trabalho é realizar uma análise fluidodinâmica de jatos sintéticos e caracterizar a troca térmica de jatos sintéticos colidindo sobre uma superfície aquecida, através de simulação numérica. A flexibilidade da aproximação numérica também possibilita o estudo da sensibilidade do design a vários parâmetros físicos e geométricos, tais como o número de Reynolds, a frequência do atuador, o número de Prandtl, a distância da placa aquecida ao orifício da cavidade, o formato do orifício do atuador, a profundidade da cavidade e a espessura da placa do orifício. Os resultados caracterizam o efeito dos parâmetros físicos e geométricos de interesse na formação do jato e na dissipação térmica. O conhecimento agregado neste estudo permitiu determinar uma correlação para o número de Nusselt em função da frequência adimensional – o número de Strouhal – do número de Reynolds, do número de Prandtl e da distância adimensional da superfície aquecida ao orifício. Assim, é possível prever o comportamento de tais jatos sobre a superfície aquecida, e assim contribuir para os atuais estudos nesta linha de pesquisa. Os resultados apresentados tem então aplicação em estudos posteriores, de maior complexidade de design com atuadores combinados com trocadores de calor de aletas, coolers e micro canais, resultando em avanços na área de resfriamento de microchips.
Current electronic components are becoming ever more potent and densly integrated, which requires further increases in the efficiency of heat dissipation. With current fan-based heat dissipation techniques with air as the working fluid becoming outdated, there is a pressing need to develop more eficient methods to cope with demand. So far, three techniques have been the primary focus of studies in this area: liquid cooling, microchannel heat exchangers and synthetic jets used to promote increased momentum transfer. Analysis of such devices at the small physical scale of electronic components is somewhat problematic in experimental form so that a computational fluid dynamics (CFD) approach is recommended. The main objective of this study is thus to utilize a CFD approach to establish the performance characteristics of a synthetic jet impacting against a heated surface. The flexibility of a numerical approach also allows the examination of the sensibility of the design with respect to several physycal and geometric parameters such as Reynolds number, pulsing frequency, jet orifice shape and size, cavity size and distance between the heated surface and the device. Such results, provide insight in the effect of physical and geometric parameters in the jet formation and heat dissipation. The combined knowledge of this study allowed the development of a practical correlation for the Nusselt number based on the Strouhal number (normalized pulsing frequency), Reynolds number, Prandtl number and the distance between the heated surface and the synthetic jet. This result allows improved predictions of a jet impacting against a heated surface and, consequently, adds an important contribution to other studies in this area. It is expected that the results presented here will be the starting point for further work, in which increasingly complex geometries such as actuators combined with heat exchangers equipped with fins, coolers or microchannels are examined to further improve the knowledge in the field of electronic cooling.

This dissertation investigates art and architecture journals as spaces of discursive construction and as privileged instruments of transnational circulation. Its focus are the relations between the Brazilian and French scenes from 1930 to 1960, with particular emphasis on the transformations undergone after the end of the Second World War, both in artistic and critical production, in the reciprocal representation of two different cultural contexts and in the negotiation of their places within the new geopolitical order. Widely distributed in South America, André Bloc’s journals are closely linked to his militancy in favour of the synthesis of the arts and of geometric abstraction. During post-war reconstruction in France, abstraction and synthesis of the arts are perceived as the driving forces of a great humanist and universalist renewal, and they are simultaneously at the core of the Brazilian journals launched in the early 1950s, which were engaged in defining the qualities of an authentic and modern national art. Following the various stakes at play in these two cultural scenes, a decentralized and post-Occidentalist perspective brings to light the different meanings attributed in Europe and in Latin America to the same theoretical vocabulary, contributing to the formulation of diverse but mutually dependent narratives concerning Brazilian art and architecture. As “constructed” spaces, the journals mirror new cartographies which furnish the basis for rethinking the relations between centre(s) and periphery(ies), while different discourses about art and architecture prefigure as many aesthetic, social and political models

This study propose a Geometric Recursive Pattern Synthesis system, using the Planetary Surround Model to draw closed symmetrical geometric patterns. The system is based on HTML and Javascript. Users can quickly generate all kinds of geometric recursive patterns by adjusting different parameters. Then arrange, combine, color the generated patterns to create a perfect pattern work with personal style. In addition to the pattern synthesis, the generating process of the Planetary Surround Model can also be understood through animation playback.

Traditional supervised machine learning classifiers are challenged to learn highly skewed data distributions as they are designed to expect classes to equally contribute to the minimization of the classifiers cost function. Moreover, the classifiers design expects equal misclassification costs, causing a bias for underrepresented classes. Thus, different strategies to handle the issue are proposed by researchers. The modification of the data set managed to establish since the procedure is generalizable to all classifiers. Various algorithms to rebalance the data distribution through the creation of synthetic instances were proposed in the past. In this paper, we propose a new oversampling algorithm named G-SOMO, a method that is inspired by our previous research. The algorithm identifies optimal areas to create artificial data instances in an informed manner and utilizes a geometric region during the data generation to increase variability and to avoid correlation. Our experimental setup compares the performance of G-SOMO with a benchmark of effective oversampling methods. The oversampling methods are repeatedly validated with multiple classifiers on 69 datasets. Different metrics are used to compare the retrieved insights. To aggregate the different performances over all datasets, a mean ranking is introduced. G-SOMO manages to consistently outperform competing oversampling methods. The statistical significance of our results is proven.

Synthetic Aperture Radar (SAR) is an active microwave remote sensing systemregardless of the influence of weather and the time of detecting. It is a very important source of remote sensing data using SAR to acquire the high-resolution on imagery for general or military purposes. Due to the fact that the land changes rapidly and the cost is increased, the use of effective measuring techniques to survey the land has become more significant. This paper focuses on the precise determination of the satellite orbit parameters from the MPH (MainProduct Header) documented by ERS-1. The main features developed here is for the geometric calibraction of the remote sensing imagery, which contributes to thesatellite orbit precision. Furthermore, affer the preciser orbit parameters aredecided, the resampling imagery makes registration with the relief map. As acomplementary information, the data of the land can be appropriately justifed.
