Повний текст джерелаIn this thesis, we study the fine properties of solutions to quasilinear elliptic and parabolic equations involving non-local and non-standard growth. We focus on three different types of partial differential equations (PDEs).Firstly, we study the qualitative properties of weak and strong solutions of the evolution equations with non-standard growth. The importance of investigating these kinds of evolutions equations lies in modeling various anisotropic features that occur in electrorheological fluids models, image restoration, filtration process in complex media, stratigraphy problems, and heterogeneous biological interactions. We derive sufficient conditions on the initial data for the existence and uniqueness of a strong solution of the evolution equation with Dirichlet type boundary conditions. We establish the global higher integrability and second-order regularity of the strong solution via proving new interpolation inequalities. We also study the existence, uniqueness, regularity, and stabilization of the weak solution of Doubly nonlinear equation driven by a class of Leray-Lions type operators and non-monotone sub-homogeneous forcing terms. Secondly, we study the Kirchhoff equation and system involving different kinds of non-linear operators with exponential nonlinearity of the Choquard type and singular weights. These type of problems appears in many real-world phenomena starting from the study in the length of the string during the vibration of the stretched string, in the study of the propagation of electromagnetic waves in plasma, Bose-Einstein condensation and many more. Motivating from the abundant physical applications, we prove the existence and multiplicity results for the Kirchhoff equation and system with subcritical and critical exponential non-linearity, that arise out of several inequalities proved by Adams, Moser, and Trudinger. To deal with the system of Kirchhoff equations, we prove new Adams, Moser and Trudinger type inequalities in the Cartesian product of Sobolev spaces.Thirdly, we study the singular problems involving nonlocal operators. We show the existence and multiplicity for the classical solutions of Half Laplacian singular problem involving exponential nonlinearity via bifurcation theory. To characterize the behavior of large solutions, we further study isolated singularities for the singular semi linear elliptic equation. We show the symmetry and monotonicity properties of classical solution of fractional Laplacian problem using moving plane method and narrow maximum principle. We also study the nonlinear fractional Laplacian problem involving singular nonlinearity and singular weights. We prove the existence, uniqueness, non-existence, optimal Sobolev and Holder regularity results via exploiting the C^1,1 regularity of the boundary, barrier arguments and approximation method

Повний текст джерелаThis thesis elaborates on the wealth maximization problem of a small investor who invests in a financial market. Key tools for our studies come across in the form of several classes of BSDEs with particular non-linearities, casting them outside the standard class of Lipschitz continuous BSDEs. We first give a characterization of a small investor''s optimal wealth and its associated optimal strategy by means of a systems of coupled equations, a forward-backward stochastic differential equation (FBSDE) with non-Lipschitz coefficients, where the backward component is of quadratic growth. We then examine how specifying concrete utility functions give rise to another class of non-standard BSDEs. In this context, we also investigate the relationship to a modeling approach based on random fields techniques, known by now as the backward stochastic partial differential equations (BSPDEs) approach. We continue with the presentation of a numerical method for a special type of quadratic BSDEs. This method is based on a stochastic analogue to the Cole-Hopf transformation from PDE theory. We discuss its applicability to numerically solve indifference pricing problems for contingent claims in an incomplete market. We then proceed to BSDEs whose drifts explicitly incorporate path dependence. Several analytical properties for this type of non-standard BSDEs are derived. Finally, we devote our attention to the problem of a small investor who is equipped with several exercise rights that allow her to collect pre-specified cashflows. We solve this problem by casting it into the language of multiple optimal stopping and develop a martingale dual approach for characterizing the optimal possible outcome. Moreover, we develop regression based Monte Carlo algorithms which simulate efficiently lower and upper price bounds.
Seloula, Nour El Houda. "Mathematical analysis and numerical approximation of the Stokes and Navier-Stokes equations with non standard boundary conditions." Pau, 2010. http://www.theses.fr/2010PAUU3030.
Повний текст джерелаThis work of thesis deals with the solving of the Stokes problem, first with boundary conditions on the normal component of the velocity field and the tangential component of the vorticity, next with boundary conditions on the pressure and the tangential component of the velocity field. In each case, we give existence, uniqueness and regularity of solutions. The case of very weak solutions is also treated by using a duality argument. The functional framework that we have choosed is that of Banach spaces of type H(div) and H(rot) or their intersection based on the space Lp, with 1 < p < 1. In particular, we suppose that is multiply connected and that the boundary R is not connexe. We are interested in a first time by some Sobolev inequality for vector fields u 2 Lp(). In a second time, we give some results concerning vector potentials with different boundary conditions. This allow to establish Helmholtz decompositions and Inf-Sup condition when the bilinear form is a rotational product. Due to these non standard boundary conditions, the pressure is decoupled from the system. It is the reason whay we are naturally reduced to solving elliptic problems which are the Stokes equations without the pressure term. For this, we use the Inf-Sup conditions, which plays a crutial role in the existence and uniqueness of solutions. We give an application to the Navier-Stokes equations where the proof of solutions is obtained by applying a fixed point theorem over the Oseen equations. Finally, two numerical methods are proposed inorder to approximate the Stokes problem. First, by means of the Nitsche method and next by means of the iscontinuous Galerkin method. Some numerical results of convergence verifying the theoretical predictions are given

For the recent years, there has been a growing interest in Lorentz-violating theories. Studies have been carried out addressing the inclusion of Lorentz-violating terms into the Standard Model (SM). This has led to the development of the Standard Model Extension (SME), which is a framework containing modifications that are power-counting renormalizable and consistent with the gauge structure of the SM. More recently, a nonminimal version of the SME was developed for the photon, neutrino, and fermion sector additionally including higher-derivative terms. One of the new properties of this nonminimal version is the lost of renormalizability. In this work, we study the main aspects of a modified Dirac theory in the nonminimal Standard-Model Extension. We focus on two types of operators namely, pseudovector and two-tensor operators. These two operators display an unusual property; they break the degeneracy of spin. This new property becomes manifest in providing two di erent dispersion relations, one for each spin projection. To solve the Dirac equation modified by those operators, we introduce a new method that was suggested by Kostelecký and Mewes in a recent research paper. This method allows to block-diagonalizing the modified Dirac equation and, thus, permits us to obtain the spinors. The objectives of the current work are as follows. First, we will review the main concepts for understanding the SME. Second, we will introduce how to extend the minimal fermion sector to the nonminimal one. Third, we will describe the method that block-diagonalizes the modified Dirac equation and we will compute the field equations. And,finally, we will get the exact dispersion relations and the spinor solutions for operators of arbitrary mass dimension.
Nos últimos anos, houve um aumento significativo no interesse em teorias que violam a simetria de Lorentz. Estudos têm sido realizados na tentativa de incluir termos que violam a simetria de Lorentz no Modelo Padrão (MP). Esta tentativa culminou no surgimento do chamado Modelo Padrão Estendido (MPE). Este modelo contempla todas as possíveis modificações que são consistentes com as propriedades já bem estabelecidas, tais como renormalizabilidade e a estrutura de gauge do MP. Mais recentemente, uma versão não-mínima do MPE foi desenvolvida para os setores dos fótons, neutrinos e para os férmions. Esta versão não-mínima caracteriza-se pela presença de altas derivadas. Uma das novas propriedades nesta versão não-mínima é a perda da renormalizabilidade. Neste trabalho, estudamos os principais aspectos da teoria de Dirac modi cada no MPE não-mínimo. Nós nos concentramos em dois tipos de operadores a saber, operadores pseudovetoriais e tensoriais. Estes dois operadores exibem uma propriedade incomum, eles quebram a degenerescência de spin. Esta nova propriedade manifesta-se, por exemplo, na presença de duas relações de dispersão diferentes, uma para cada projeção do spin. Para resolver a equação de Dirac modi cada por esses operadores, introduzimos um novo método que foi sugerido por Kostelecký e Mewes em um trabalho recente. Este método permite bloco-diagonalizar a equação de Dirac modi cada e, assim, nos fornece uma nova maneira de obter os espinores. Os objetivos do presente trabalho são os seguintes. Primeiro, iremos rever alguns conceitos essenciais para o entendimento do MPE. Segundo, apresentaremos a extens ão do setor fermiônico mínimo para o não-mínimo. Terceiro, descreveremos o método que bloco-diagonaliza a equação de Dirac modi cada e calcularemos as equações de campo. Por fim, calcularemos as relações de dispersão exatas e as soluções espinoriais para cada configuração não-mínima dos operadores citados.

Повний текст джерелаMaster thesis solved differential equation of diffusion of new techniques methods. Having analyzed the standard variable diffusion coefficient parabolic equation solution methods suggested in this work we solve these equations using the so-called "bridge" function. Tried two types of "bridge" functions: tangent hyperbolic and trigonometric. Differential equation, the solution we were looking for a "bridge" function and the amount of products of powers of polynomials: trigonometry "bridge" function and hyperbolic tangent of a "bridge" function. We have received computer-based solutions and the solutions found at the margins. A comparison of hyperbolic tangent trigonometric "bridge" function of the error standard deviations have received, the more accurate the hyperbolic tangent of a "bridge" function approach.

Повний текст джерелаNumerical modelling and simulation of interfaces in fluid and solid mechanics are at the heart of many applications, such as cell biology (deformation of red blood cells), petroleum engineering and seismic (reservoir modelling, presence of faults, wave propagation), aerospace and civil engineering etc. This thesis focuses on the approximation of interface and interphase problems in fluid mechanics by means of the NXFEM method, which takes into account discontinuities on non-aligned meshes.We have first focused on the development of NXFEM for nonconforming finite elements in order to take into account the interface between two media. Two approaches have been proposed, for Darcy and Stokes equations. The first approach consists in modifying the basis functions of Crouzeix-Raviart on the cut cells and the second approach consists in adding some stabilization terms on each part of a cut edge. We have studied them from a theoretical and a numerical point of view. Then we have studied the asymptotic modelling and numerical approximation of interphase problems, involving a thin layer between two media. We have first considered the Darcy equations in the presence of a highly permeable fracture. By passing to the limit in the weak formulation, we have obtained an asymptotic model where the 2D fracture is described by an interface with adequate transmission conditions. A numerical method based on NXFEM with conforming finite elements has been developed for this limit problem, and its consistency and uniform stability have been proved. Numerical tests including a comparison with the literature have been presented. The asymptotic modelling has been finally extended to Stokes equations, for which we have justified the limit problem. Finally, we have considered the mechanical behaviour of red blood cells in order to better understand blood rheology. The last part of the thesis is devoted to the modelling of the membrane of a red blood cell by a non-Newtonian viscoelastic liquid, described by the Giesekus model. For an interphase problem composed of two Newtonian fluids (the exterior and the interior of the red blood cell) and a Giesekus liquid (the membrane), we formally derived the limit problem where the equations in the membrane are replaced by transmission conditions on an interface

Повний текст джерелаThis thesis is devoted to showing the existence of global-in-time solutions to some nonlinear equations, including the wave-Klein-Gordon equations and the Dirac equations. For the wave-Klein-Gordon-Dirac equations, based on the hyperboloidal foliation method we establish several global stability results, explore the asymptotic behaviors of these solutions, and study how the solutions are affected when some mass parameters go to certain limits. As an application, we can prove that several physical models are globally stable: the Dirac-Klein-Gordon model, the Dirac-Proca model, the Klein-Gordon-Zakharov model, the U(1) model of electroweak interactions and so on. In Part I, we study the electroweak standard model. We first prove the global nonlinear stability results for the U(1) model, where we obtain uniform energy bounds (modulo a slow logarithm growth). Next we move to the full standard model, and get global stability results in some special cases. In Part II, we analyse a class of coupled wave-Klein-Gordon equations with critical nonlinearities, and prove the existence of global-in-time solutions which enjoy sharp pointwise decay property. Besides we study a class of Klein-Gordon equations with possibly vanishing mass, and prove sharp pointwise decay results which are uniform in its mass. In Part III, we mainly investigate the hyperbolic Fourier transform, and derive a new L2-type estimate for waves

Повний текст джерелаDissertation examines mutual influence between cold dark matter sector and extended Higgs sector in two popular supersymmetric generalizations of the Standard Model (MSSM, NMSSM). The study is focused on the relic density and direct detection of dark matter as well as on the LHC search for new physics. Special emphasis has been placed on estimation of experimentally allowed parameter space of the models under consideration. Subsequently, Boltzmann equation for relativistic species is derived and applied to the analysis of hot dark matter in S.~Weinberg's Higgs portal model. The results obtained with our method are also compared with some popular approximations of dark matter relic density calculation.

Повний текст джерела(7011101), Ricki Lauren McKee. "Implementing Common Core Standards for Mathematics: Focus on Problem Solving." Thesis, 2019.
Знайти повний текст джерелаUtilizing action research as the methodology, this study was developed with the ultimate goal of describing and reflecting on my implementation of one aspect of the Common Core State Standards for Mathematics (CCSSM) in an algebra classroom. This implementation focused on the Problem-Solving Standard of Mathematical Practice (SMP) as described in CCSSM (Making sense of problems and persevere in solving them). The research question that guided my work was the following: How is the Common Core State Standards for Mathematics (CCSSM) Problem-Solving Mathematical Standard enacted in an algebra class while using a Standards-based curriculum to teach a quadratics unit?
I explored this by focusing on the following sub-questions:
- Q1. What opportunities to enact the components of the Problem-Solving Mathematical Standard are provided by the written curriculum?
- Q2. In what way does the teacher’s implementation of the quadratics unit diminish or enhance the opportunities to enact the components of the Problem-Solving Mathematical Standard provided by the written curriculum?
- Q3. In what ways does the teacher’s enactment of problem-solving opportunities change over the course of the unit?
Reviewing the literature related to the relevant learning theories (sociocultural theory, the situated perspective, and communities of practice), I outlined the history of CCSSM, National Council of Teachers of Mathematics (NCTM), National Research Council (NRC), and the No Child Left Behind Act of 2001. Exploring the details of CCSSM’s Standards of Mathematical Content (SMCs) and Standards of Mathematical Practice (SMPs), I discussed problem solving, the Problem Solving Components (PSCs) listed in the Problem-Solving SMP of CCSSM, teaching through problem solving, and Standards-based curricula, such as College Preparatory Mathematics (CPM) which is the algebra curricula I chose for this study.
There are many definitions of the construct problem solving. CCSSM describes this construct in unique ways specifically related to student engagement. The challenge for teachers is to not only make sense of CCSSM’s definition of problem solving and its components, but also to enact it in the classroom so that mathematical understanding is enhanced. For this reason, studies revealing how classroom teachers implemented CCSSM, especially in terms of problem solving, are necessary.
The Critical Theoretic/Action Research Paradigm is often utilized by researchers trying to improve their own practice; thus, I opted for an action research methodology because it could be conducted by the practitioner. These methods of data collection and analysis were employed in order to capture the nature of changes made in the classroom involving my teaching practice. I chose action research because this study met the key tenets of research in action, namely, a collaborative partnership concurrent with action, and a problem-solving approach.
While I knew how I wanted to change my classroom teaching style, implementing the change was harder than anticipated. From the onset, I never thought of myself as an absolute classroom authority, because I always maintained a relaxed classroom atmosphere where students were made to feel comfortable. However, this study showed me that students did view my presence as the authority and looked to me for correct answers, for approval, and/or for reassurance that they were on the right track. My own insecurities of not knowing how to respond to students in a way to get them to interact more with their group and stop looking to me for answers, while not being comfortable forcing students to talk in front of their peers, complicated this study. While it was easy to anticipate how I would handle situations in the classroom, it was hard to change in the moment.
The research revealed the following salient findings: while the written curriculum contained numerous opportunities for students to engage with the Focal PSCs, the teacher plays a crucial role in enacting the written curriculum. Through the teacher’s enactment of this curriculum, opportunities for students to engage with the Focal PSCs can be taken away, enacted as written, or enhanced all by the teacher. Additionally, change was gradual and difficult due to the complexities of teaching. Reflection and constant adapting are crucial when it comes to changing my practice.
As a classroom teacher, I value the importance of the changes that need to be made in the classroom to align with CCSSM. I feel that by being both a teacher and a researcher, my work can bridge the gap between research and classroom practice.Ncube, Nhlanhla Brian. "Comparing the equator principles' IFC performance standard 6 and the South African mining and biodiversity guideline to identify areas of overlap and gaps to improve biodiversity conservation in the mining sector." Thesis, 2015. http://hdl.handle.net/10539/19283.
Повний текст джерелаEnvironmental degradation and pollution continue to characterise the mining sector in South Africa despite a robust legislative framework which is aimed at enhancing sustainable mining practices. Of particular concern is the impact of mining on biodiversity. During 2013 the Departments of Environmental Affairs and Mineral Resources, together with the South African Mining and Biodiversity Forum, an alliance of stakeholders from industry, conservation organisations and government facilitated by the Chamber of Mines of South Africa, released the South African Mining and Biodiversity Guideline (SAMBG), which aim to mainstream biodiversity into the mining sector. The guideline seek to integrate biodiversity considerations into planning processes and manage biodiversity through the lifecycle of a mine, and so contribute to better outcomes. In addition to the guideline, mining companies that obtain funding from financial institutions that are signatory to the Equator Principles are required to implement IFC Performance Standard 6 (IFC PS6) which also deals with biodiversity conservation. There is a concern that the SAMBG adds further to the burgeoning pile of standards, guidelines and best practices that mining companies are required to meet, but without necessarily adding anything new. This research project deals with this concern through a review of the SAMBG to assess their potential contribution to biodiversity conservation and to determine, through a comparative analysis, whether any overlaps and gaps exist between the guideline and IFC PS6. A qualitative methodology was used to understand how the Aichi Biodiversity Targets are addressed by the SAMBG. Based on this review a conclusion as to the role of the SAMBG amongst the range of guidelines and standards was drawn. The research indicated that there is alignment between the SAMBG, the IFC PS6, the Aichi Biodiversity Targets and South African national environmental legislation. They all aim to achieve a similar outcome, the conservation and sustainable use of biodiversity, but provided different levels of detail and are targeted at slightly different audiences.
