▼ Dans cette thèse, nous donnons de nouveaux résultats sur la taille moyenne d’enveloppes convexes de points choisis dans un convexe. Cette taille est connue lorsque les points sont choisis uniformément (et indépendamment) dans un polytope convexe, ou un convexe suffisamment «lisse» ; ou encore lorsque les points sont choisis indépendamment selon une loi normale centrée. Dans la première partie de cette thèse, nous développons une technique nous permettant de donner de nouveaux résultats lorsque les points sont choisis arbitrairement dans un convexe, puis «bruités» par une perturbation aléatoire. Ce type d’analyse, appelée analyse lissée, a initialement été développée par Spielman et Teng dans leur étude de l’algorithme du simplexe. Pour un ensemble de points arbitraires dans une boule, nous obtenons une borne inférieure et une borne supérieure de cette complexité lissée dans le cas de perturbations uniformes dans une boule en dimension arbitraire, ainsi que dans le cas de perturbations gaussiennes en dimension 2. La taille de l'enveloppe convexe de points choisis uniformément dans un convexe, peut avoir un comportement logarithmique si ce convexe est un polytope ou polynomial s’il est lisse. Nous construisons un convexe produisant un comportement oscillant entre ces deux extrêmes. Dans la dernière partie, nous présentons un algorithme pour engendrer efficacement une enveloppe convexe aléatoire de points choisis uniformément et indépendamment dans un disque sans avoir à engendrer explicitement tous les points. Il a été implémenté en C++ et intégré dans la bibliothèque CGAL.
In this thesis, we give some new results about the average size of convex hulls made of points chosen in a convex body. This size is known when the points are chosen uniformly (and independently) in a convex polytope or in a "smooth" enough convex body. This average size is also known if the points are independently chosen according to a centered Gaussian distribution. In the first part of this thesis, we introduce a technique that will give new results when the points are chosen arbitrarily in a convex body, and then noised by some random perturbations. This kind of analysis, called smoothed analysis, has been initially developed by Spielman and Teng in their study of the simplex algorithm. For an arbitrary set of point in a ball, we obtain a lower and a upper bound for this smoothed complexity, in the case of uniform perturbation in a ball (in arbitrary dimension) and in the case of Gaussian perturbations in dimension 2. The asymptotic behavior of the expected size of the convex hull of uniformly random points in a convex body is polynomial for a "smooth" body and polylogarithmic for a polytope. In the second part, we construct a convex body so that the expected size of the convex hull of points uniformly chosen in that body oscillates between these two behaviors when the number of points increases. In the last part, we present an algorithm to generate efficiently a random convex hull made of points chosen uniformly and independently in a disk.…

▼ This research set out to investigate and build upon
the foundation for the nonparametric estimation of finite
multivariate mixture models given the conditional independence
assumption, set forth in a series of studies over the last decade.
We proposed a novel formulation of the objective function in terms
of penalized smoothed Kullback-Leibler divergence under a reduced
parameter space. A special optimization landscape and scheme was
discovered in working out the majorizationminimization method for
the estimation problem which leads to a closed form of the
nonlinearly smoothed majorization-minimization (NSMM) algorithm. We
established a sharpened monotonicity property that precisely
measures the distance between successive iterates of the algorithm
and proved the existence of a solution to the main optimization
problem for the first time in literature. The estimation theory for
this basic model together with the special optimization scheme can
be adapted to the investigation of an important extension of the
model that incorporates component-wise independent component
analysis (ICA). The NSMMICA algorithm has been developed and a
discretized version of it, which interweaves NSMM and weighted
FastICA has been implemented in the R package icamix as a
model-based clustering tool. We demonstrated the use of the newly
developed methods/algorithms by applications in image analysis and
unsupervised learning.

Advanced Development of Smoothed Finite Element Method

▼ The
smoothed finite element method (S-FEM) was
recently proposed to bring softening effects into and improve the
accuracy of the standard FEM. In the S-FEM, the system stiffness
matrix is obtained using strain smoothing technique over the
smoothing domains associated with cells, nodes, edges or faces to
establish models of desired properties. In this dissertation, it
will introduce several aspects of advanced development and
applications of S-FEM in solid mechanics. The idea, main work and
contribution are included in four aspects as following:(1) A
Generalized Stochastic Cell-based S-FEM (GS_CS-FEM): The cell-based
S-FEM is extended for stochastic
analysis based on the generalized
stochastic perturbation technique. Numerical examples are presented
and the obtained results are compared with the solution of Monte
Carlo simulations. It is found that the present GS_CS-FEM method
can improve the solution accuracy with high-efficiency for
stochastic problems with large uncertainties.(2) An effective
fracture
analysis method based on the VCCT implemented in CS-FEM:
The VCCT is formulated in the framework of CS-FEM for evaluating
SIF’s and for modeling the crack propagation in solids. The
one-step-
analysis approach of the VCCT is utilized based on the
assumption of stress field equivalence under infinitesimal
perturbations. The significant feature of the present approach is
that it requires no domain integration but attains same level of
accuracy compared to the standard FEM using the interaction
integral method. Numerical examples are provided to validate the
effectiveness of fracture parameter evaluation as well as to
predict the crack growth trajectories.(3) Smoothing techniques
based crystal plasticity finite element modeling of crystalline
materials: A framework and numerical implementation for modeling
anisotropic crystalline plasticity using strain smoothing
techniques is presented to model anisotropic crystalline plasticity
with rate-independence. The edge-based strain smoothing technique
is extended to deal with finite strains in a nonlinear incremental
integration procedure based on the Newton-Raphson scheme. Several
representative examples are studied to demonstrate the capability
of proposed method as well as the integration algorithm for
capturing the strain localization and dealing with plastic
incompressibility. The proposed method is also implemented to
explore the mesoscopic and macroscopic elaso-plastic behavior of
polycrystalline aggregates.(4) A novel beta finite element method
(ßFEM) of coupled edge/face and node based smoothing techniques:
Smoothing domains generated upon both edges (faces for 3D) and
nodes are employed to construct a
smoothed model. In this work, a
novel S-FEM is proposed, in which an adjustable parameter ß is
introduced to control the ratio of the area of
edge-based/face-based and node-based smoothing domains. It is found
that the nearly exact solution in strain energy can be obtained by
tuning the parameter, making use of the important property that the
exact solution is bonded by…

▼ Significant time and cost savings can be realized through the use of virtual simulation of testing procedures across diverse areas of research and development. Fully detailed virtual truck models using the simplified off-road rigid-ring model parameters may further increase these economical savings within the automotive industry. The determination of the off-road rigid-ring parameters is meant to facilitate the simulation of full vehicle models developed by Volvo Group Trucks Technology. This works features new FEA (Finite Element
Analysis) tire and SPH (
Smoothed Particle Hydrodynamics) soil interaction modeling techniques. The in-plane and out-of-plane off-road rigid-ring parameters are predicted for an RHD (Regional Haul Drive) truck tire at varying operating conditions. The tire model is validated through static and dynamic virtual tests that are compared to previously published literature.
Both the in-plane and out-of-plane off-road rigid-ring RHD parameters were successfully predicted. The majority of the in-plane parameters are strongly influenced by the inflation pressure of the tire because the in-plane parameters are derived with respect to the mode of vibration of the tire. The total equivalent vertical stiffness on a dry sand is not as heavily influenced by the inflation pressure compared to predictions on a hard surface. For perspective, at 110 psi, the dry sand total vertical stiffness is nearly nine times smaller than that determined on the hard surface, while the lateral stiffness on soft soil (Dry Sand) is at a minimal of three times higher than that of the corresponding values tested on a hard surface. The cornering stiffness is primarily load dependant because the inflation pressure is only noticeably influential at high vertical loads. More importantly, the soil builds in front of the tire, creating what is called a bulldozing effect, during high slip angles. The additional lateral force of the soil exerted onto the tire during cornering maneuvers may contribute to higher than expected results and may be confirmed through future investigation of the cohesion of the soil model.

Three-Dimensional Bedrock Channel Evolution with Smoothed Particle Hydrodynamics.

▼ Bedrock channels are responsible for balancing and communicating tectonic and climatic signals across landscapes, but it is difficult and dangerous to observe and measure the flows responsible for removing weakly-attached blocks of bedrock from the channel boundary. Consequently, quantitative descriptions of the dynamics of bedrock removal are scarce. Detailed numerical simulation of violent flows in three dimensions has been historically challenging due to technological limitations, but advances in computational fluid dynamics aided by high-performance computing have made it practical to generate approximate solutions to the governing equations of fluid dynamics. From these numerical solutions we gain detailed knowledge of the motions and forces of flowing water, which deepens our understanding of earth processes responsible for shaping landscapes.
By simulating hydraulic forces generated by flowing water in bedrock channels with interconnected zones of weakness, I explore the implications of fluvial stresses, boulder impact, and rock fabric heterogeneity on landscape form. I use a
Smoothed Particle Hydrodynamics (SPH) solver to simulate flow over landscapes and I use stress-strength
analysis to calculate earth fabric failure using the Failure Earth Response Model (FERM). SPH modeling is used to simulate the hydraulic mobilization of a boulder in a bedrock channel and to quantify the forces associated with its subsequent rolling, sliding, and impact two-meter freefall. FERM model results reveal that strength gradients in fractured bedrock topographies exert more control on volume of eroded material and channel form than the overall strength of the surrounding bedrock.
Finally, SPH model results are calibrated with three-dimensional water velocity measurements collected by an acoustic doppler current profiler in the Penobscot River. SPH modeling is used to explore the influence of in-stream logging structures on channel velocity, which has implications for the habitat of federally-protected diadromous fish species in the Penobscot River. Model results show that even at low discharges, the presence of in-stream structures changes the velocity structure at ~10
2 m length scales.

▼ São analisados nesta dissertação problemas em teoria dos jogos, com enfoque no efeito que perturbações acarretam em jogos. A análise suavizada (smoothed analysis) é utilizada para tal análise, e dois tipos de jogos são o foco principal desta dissertação, jogos bimatrizes e o problema de atribuição de tráfego (Traffic Assignment Problem.) O algoritmo de Lemke-Howson é um método utilizado amplamente para computar um equilíbrio Nash de jogos bimatrizes. Esse problema é PPAD-completo (Polynomial Parity Arguments on Directed graphs), e existem instâncias em que um tempo exponencial é necessário para terminar o algoritmo. Mesmo utilizando análise suavizada, esse problema permanece exponencial. Entretanto, nenhum estudo experimental foi realizado para demonstrar na prática como o algoritmo se comporta em casos com perturbação. Esta dissertação demonstra como as instâncias de pior caso conhecidas atualmente podem ser geradas e mostra que a performance do algoritmo nestas instâncias, quando perturbações são aplicadas, difere do comportamento esperado provado pela teoria. O Problema de Atribuição de Tráfego modela situações em uma rede viária onde usuários necessitam viajar de um nodo origem a um nodo destino. Esse problema pode ser modelado como um jogo, usando teoria dos jogos, onde um equilíbrio Nash acontece quando os usuários se comportam de forma egoísta. O custo total ótimo corresponde ao melhor fluxo de um ponto de vista global. Nesta dissertação, uma nova medida de perturbação é apresentada, o Preço da Anarquia Suavizado (Smoothed Price of Anarchy), baseada na análise suavizada de algoritmos, com o fim de analisar os efeitos da perturbação no Preço da Anarquia. Usando esta medida, são estudados os efeitos que perturbações têm no Preço da Anarquia para instâncias reais e teóricas para o Problema de Atribuição de Tráfego. É demonstrado que o Preço da Anarquia Suavizado se mantém na mesma ordem do Preço da Anarquia sem perturbações para funções de latência polinomiais. Finalmente, são estudadas instâncias de benchmark em relação à perturbação.
This thesis analyzes problems in game theory with respect to perturbation. It uses smoothed analysis to accomplish such task and focuses on two kind of games, bimatrix games and the traffic assignment problem. The Lemke-Howson algorithm is a widely used algorithm to compute a Nash equilibrium of a bimatrix game. This problem is PPAD-complete (Polynomial Parity Arguments on Directed graphs), and there exists an instance which takes exponential time (with any starting pivot.) It has been proven that even with a smoothed analysis it is still exponential. However, no experimental study has been done to verify and evaluate in practice how the algorithm behaves in such cases. This thesis shows in detail how the current known worst-case instances are generated and shows that the performance of the algorithm on these instances, when perturbed, differs from the expected behavior proven in theory. The Traffic Assignment Problem models a situation in a road network where users want to…

▼ [Truncated abstract] The hydrodynamics of wave impact on offshore structures is not well understood. Wave impacts often involve large deformations of water free-surface. Therefore, a wave impact problem is usually combined with a free-surface problem. The complexity is expanded when the body exposed to a wave impact is allowed to move. The nonlinear interactions between a moving body and fluid is a complicated process that has been a dilemma in the engineering design of offshore and coastal structures for a long time. This thesis used experimental and numerical means to develop further understanding of the wave impact problems as well as to create a numerical tool suitable for simulation of such problems. The study included the consideration of moving boundaries in order to include the coupled interactions of the body and fluid. The thesis is organized into two experimental and numerical parts. There is a lack of benchmarking experimental data for studying fluid-structure interactions with moving boundaries. In the experimental part of this research, novel experiments were, therefore, designed and performed that were useful for validation of the numerical developments. By considering a dynamical system with only one degree of freedom, the complexity of the experiments performed was minimal. The setup included a plate that was attached to the bottom of a flume via a hinge and tethered by two springs from the top one at each side. The experiments modelled fluid-structure interactions in three subsets. The first subset studied a highly nonlinear decay test, which resembled a harsh wave impact (or slam) incident. The second subset included waves overtopping on the vertically restrained plate. In the third subset, the plate was free to oscillate and was excited by the same waves. The wave overtopping the plate resembled the physics of the green water on fixed and moving structures. An analytical solution based on linear potential theory was provided for comparison with experimental results. ... In simulation of the nonlinear decay test, the SPH results captured the frequency variation in plate oscillations, which indicated that the radiation forces (added mass and damping forces) were calculated satisfactorily. In simulation of the nonlinear waves, the waves progressed in the flume similar to the physical experiments and the total energy of the system was conserved with an error of 0.025% of the total initial energy. The wave-plate interactions were successfully modelled by SPH. The simulations included wave run-up and shipping of water for fixed and oscillating plate cases. The effects of the plate oscillations on the flow regime are also discussed in detail. The combination of experimental and numerical investigation provided further understanding of wave impact problems. The novel design of the experiments extended the study to moving boundaries in small scale. The use of SPH eliminated the difficulties of dealing with free-surface problems so that the focus of study could be placed on the impact forces on fixed and…

▼ In recent years, the advancement of computerized
modeling has allowed for the creation of extensive pneumatic tire
models. These models have been used to determine many tire
properties and tire-road interaction parameters which are either
prohibitively expensive or unavailable with physical models. More
recently, computerized modeling has been used to explore tire-soil
interactions. The new parameters created by these interactions were
defined for these models, but accurate soil constitutive equations
were lacking. With the previous models, the soil was simulated
using Finite Element Analysis (FEA) with soil material models
requiring calibration and validation. Furthermore, the meshless
modeling method of Smooth Particle Hydrodynamics (SPH) may be a
viable approach to more accurately simulating large soil
deformations and complex tire-soil interactions. For this thesis, a
rigid tire model is used to perform an extensive sensitivity study
on the previously used FEA soft soil (dense sand) in order to
determine the importance of mesh size, soil plot size, and edge
constraints. Then, parameters for SPH particles are determined for
either complete or partial replacement of FEA elements in the soil
model. Rolling resistance tests are conducted with a rigid tire
model for different SPH and FEA/SPH soil models and compared to the
previously determined best FEA soil model. Replacement of FEA
elements with SPH particles is found to be the key variable as
using a deeper amount of SPH particles increases rolling resistance
while increasing the SPH particle density has little effect on
rolling resistance. These results are then replicated using a
pneumatic tire model. For further validation, pressure-sinkage
tests are conducted with the FEA and SPH soils to explore the
differences in the two soil modeling methods. Also,
shear-displacement tests are conducted with the SPH soil—a test
which cannot easily be performed with an FEA soil model. These
shear tests show that the SPH soil behaves more like a clay in
initial shearing and more like a sand by exhibiting increased
shearing due to vertical loading. Furthermore, both the
pressure-sinkage and shear-displacement tests still indicate that a
larger particle density is unnecessary.

▼ Algorithms that have good worst-case performance are not always the ones that perform best in practice. The
smoothed analysis framework is a way of analyzing algorithms that usually matches practical performance of these algorithms much better than worst-case
analysis. In this thesis we apply
smoothed analysis to two classes of algorithms: minimum-cost flow algorithms and belief propagation algorithms. The minimum-cost flow problem is the problem of sending a prescribed amount of flow through a network in the cheapest possible way. It is very well known, and over the last half a century many algorithms have been developed to solve it. We analyze three of these algorithms (the successive shortest path algorithm, the minimum-mean cycle canceling algorithm, and the network simplex algorithm) in the framework of
smoothed analysis and show lower and upper bounds on their
smoothed running-times. The belief propagation algorithm is a message-passing algorithm for solving probabilistic inference problems. Because of its simplicity, it is very popular in practice. However, its theoretical behavior is not well understood. To obtain a better theoretical understanding of the belief propagation algorithm, we apply it to several well-studied optimization problems. We analyze under which conditions the belief propagation algorithm converges to the correct solution and we analyze its
smoothed running-time.

▼ Tato disertační práce se věnuje problematice zobrazení signálu v časo-frekvenční oblasti s konstantním rozlišením. V teoretickém úvodu jsou shrnuty možnosti zobrazení signálu v čase a frekvenci. Zejména je soustředěna pozornost na srovnání krátkodobé Fourierovy transformace (STFT) s Wignerovou-Villeovou distribucí (WVD). Druhá zmíněná dosahuje výrazně lepšího rozlišení, a to zejména pro lineárně frekvenčně modulovaný signál. Dále je podrobně popsána nevýhoda WVD, kterou je přítomnost interferencí plynoucích z výpočtu okamžité autokorelační funkce. Tyto interference jsou způsobeny přítomností více složek signálu nebo jeho nelineární modulací. Následně je rozebrána celá řada metod, kterými je možné zmíněné interference potlačit, ovšem za cenu ztráty rozlišení. Jednou z možností potlačení je využití vyhlazené pseudo Wignerovy-Villeovy distribuce. Ta je v práci dále využita pro analýzu potlačení interferencí při různé filtraci v časo-frekvečním prostoru. Jsou použity různé typy vícesložkových signálů a také různé typy nelineárních modulací. Na základě provedené analýzy je navržena metoda, využívající sadu různě vyhlazených pseudo Wignerových-Villeových distribucí, která odhaduje časo-frekvenční reprezentaci signálu s vysokým rozlišením a minimálními interferencemi. Pro porovnání dosažených výsledků s jinými metodami jsou srovnány v literatuře používané kvantitativní metriky. Pro výběr vhodné metriky je navržena vlastní metrika. Ta je aplikovatelná na simulované signály a využívá střední kvadratickou odchylku. Na základě srovnání je vybrána Stankovićova metrika jako nejvhodnější pro porovnání výsledků. Vybraná metrika je nejdříve použita pro určení vhodného minimálního počtu využitých různě vyhlazených pseudo Wignerový-Villeových distribucí. Pomocí vybrané metriky je navržená metoda porovnána s dalšími metodami. Těmi jsou STFT s optimalizovanou délkou okna, S-metoda s optimalizovaným parametrem a optimalizační metoda využívající radiálního Gaussova jádra (RGK). Zmíněné metody jsou porovnány na sadě signálů použité dříve pro analýzu potlačení interferencí. Navíc je k signálům přidán také šum. Nakonec jsou metody srovnány také na reálném signálu netopýřího echa. V závěru je shrnuto, že navrhovaná metoda předčí porovnávané metody co do potlačení interferencí a kvality rozlišení.; The doctoral thesis focuses on signal representation in the time-frequency domain with constant resolution. In theoretical introduction the possibilities of displaying a signal in time and frequency are summarized. Attention is concentrated on comparison of short-time Fourier Transform (STFT) and Wigner-Ville Distribution (WVD). The latter achieves a significantly better resolution, especially for a linearly modulated signal. The disadvantage of WVD, which is the presence of interferences resulting from the calculation of the instantaneous autocorrelation function, is described in detail. These interferences are due to the presence of multiple components in the signal or its non-linear modulation. Subsequently, several methods are discussed,…

▼ This thesis has two main objectives. The first is to propose multivariate methods for the study of socioeconomic inequalities in mortality in small areas. The second is to study socioeconomic inequalities in mortality in small areas of several Spanish cities. Four different studies were conducted to attain these objectives: two of them focussed on the methodological aspects and the other two being empirical studies focussed on the study of inequalities. The first methodological study proposes the Bayesian factor
analysis to calculate a deprivation index. Additionally, this study concludes that ignoring the uncertainty obtained in the estimation of the index may result in a misclassification bias when the areas are grouped according to quantiles of the index. In the second methodological study the SANOVA model has been reformulated enabling the introduction of a covariate in the model. Also, this reformulation permits the decomposition of the variance of the studied patterns into the sum of variances of all the model components. Finally, the other studies show the existence of socioeconomic inequalities in total mortality and mortality by specific causes in eleven major Spanish cities. In addition, for ischemic heart disease these inequalities appear to increase slightly over time.
