····· lezzter Preis 44.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Loop space recognition is well understood in the context of traditional topology, however many principles for loop space characterization can be generalized to contexts besides topological spaces. Quillen introduced model categories as categories that have properties sufficient to define a homotopy theory consistent with the classical notion from topology. These categories can be understood by a class of morphisms called weak equivalences that yield isomorphism in the defined homotopy theory. When a model category possesses sufficiently rich combinatorial properties, the class of weak equivalences can be enlarged in a localization of the category. This work explores recognition principles, consistent with classical loop space recognition, in the context of model categories with localization. Analogues to the classical topological loop functors are provided in these categories with a corresponding recognition principle. ····· 1036118716
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Navier-Stokes equations are the most fundamental equations in Newtonian fluid mechanics. But for the last few decades it has been generally accepted that the Newtonian fluid flow models are not able to explain certain phenomena which has been reported for the fluids flow in industry and other technological applications. Indeed it is the non-Newtonian fluid models which best describe these phenomena. Among the several non-Newtonian fluid models, the second and third grade fluids have received the attention of many researches. Particularly, non-Newtonian fluids with magnetic field under the influence of Hall currents have been investigated more, mainly due to their abundant applications in various industries and different engineering disciplines. The equations describing the motion of these fluids are highly non-linear partial differential equations and therefore present a special challenge to engineers, physicists and mathematicians. Furthermore, due to the non-linearity there are only a few analytical solutions available in the literature. In this report we present some analytic solutions for Oldroyd-B, second and third grade fluids under different geometrical configurations. ····· 1036118691

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The discrete groups which are fundamental groups of manifolds are at the heart of some of the most challenging problems in geometry and topology. These problems have motivated mathematicians to use both geometry and functional analysis (including C -algebras) to study groups. This geometry and functional analysis approach is culminated in the statement of the Baum-Connes conjecture. K- theory is the language of the Baum-Connes conjecture, as well as the setting for most approaches to its proof. The study of K-nuclearity of C -algebras and K-amenability of groups have contributed significantly to our understanding of the Baum-Connes conjecture. Similarly, K-exactness of C -algebras and groups is the K-theoretic version of exactness. Indeed, a group G is called K-exact if the minimal tensor product by Cr G preserves the K-theoretic cyclic six-term exact sequence, regardless of whether it preserves short exact sequences of C -algebras. It is known that every coarsely embeddable group satisfies the coarse Baum-Connes. In this work we investigate the relationship between K-exactness and coarse embeddability of groups into a Hilbert space H. ····· 1036118635

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The theory of binomial enumeration is variously called the calculus of finite differences or the Umbral calculus. This theory studies the analogies between various sequences of polynomials pn and the powers sequence xn. The subscript n in pn was thought of as the shadow ( Umbra means Shadow in Latin, whence the name umbral calculus) of the subscript n in xn, and many parallels were discovered between such sequences.At the very outset a brief explanation of the term modern umbral calculus is given. A large part of applied analysis is concerned with the study of certain sequences of special polynomials. Some of the most important of these sequences are associated with the names of Jacobi, Gegenbauer, Legendre, Chebyshev, Bessel, Laguerre, Hermite and Bernoulli. All of these sequences and many more, fall into a special class. Boas and Buck, in their work on polynomial expansions of analytic functions, used the term sequence of generalized Appell type for members of this class. ····· 1036118327
für 49.41€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Mathematics is most often associated with the task of solving equations. Indeed, many problems in biology, economics, physics, and engineering involve equations and mathematics is the one to provide methods for solving them. But any equation of the form f(x) = 0 can be transformed into a new problem by a simple transformation: F(x) = f(x)+x = x. Points that remains invariant under the action of a function are called fixed points. When interested in the existence of solutions to generalized real life problems the question can be translated into asking about whether the problem has fixed points. ····· 1036118311
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The function concept is one of the fundamental constructs in school mathematics and teachers need to have a firm and flexible grasp of this construct. Dr Nyikahadzoyi investigated prospective high school mathematics teachers understanding of this construct. A sophisticated conceptual framework using historical sources and constructs from mathematical learning theories was constructed to guide the investigation. This framework was applied to prospective teachers responses to items related to functions. The conclusion reached is that prospective teachers hold primarily a process conception of a function and this influences the pedagogical decisions that they make. The thesis moves beyond the level of description of students understanding of the concept of a function. A revised conceptual framework is proposed. This is the major strength of this dissertation. The revised framework will in fundamental ways influence haw learning experiences will be organized for prospective teachers to graduate with a flexible understanding of the concept of a function. ····· 1036118300
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Starting with the pioneering work of Schoenberg [1], the theory of spline functions and its applications have received much international importance and reorganization in recent years. We very often come across the interpretations of phenomenon in scientific studies which are generally described by functions. Often such functions do not have nice mathematical properties like differentiability, integrability etc. The absence of these useful mathematical properties makes it very difficult to handle with these functions which are so crucial for the study. Thus, in the direction of studies of these functions we replace these functions by an approximating functions having nice mathematical properties. Spline functions are essentially piecewise polynomial functions which meet certain smoothness requirement. The different pieces of spline functions of a certain order provide much greater degree of freedoms in comparison to polynomial functions of the same order. The choice of these degree of freedom in spline functions makes them quite flexible. ····· 1036118277
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book deals with the theoretical and the computational aspects of the classical Tower of Hanoi Problem (THP) and its multi-peg generalization. Chapter 1 reviews the classical THP in its general form with n( 1) discs and 3 pegs, with the algorithms, both recursive and iterative. Chapter 2 considers the multi-peg generalization with n discs and p pegs, and gives some local-value relationships satisfied by M(n,p), kmin(n,p) and kmax(n,p), where M(n,p) is the presumed minimum number of moves, and kmin(n,p) and kmax(n,p) are the optimal partition numbers, and presents a recursive algorithm Chapter 3 gives the closed-form expressions for M(n,4), kmin(n,4) and kmax(n,4), and gives an iterative algorithm based on the divide-and-conquer approach. It is shown that, for n 6, the presumed minimum solution is the optimal solution. Chapter 4 extends the results of Chapter 3 to find the explicit forms of M(n,p), kmin(n,p) and kmax(n,p), and establishes the equivalence of four formulations of the multi-peg THP. The divide-and-conquer approach has also been extended. ····· 1036118251

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book presents a review and development of classification and knowledge-based methods. It focuses on linearly and nonlinearly separable binary classification problems, which are then generalized to solve multi-categorical discrimination problems. In the case of nonlinearly separable classification problems, kernel functions are used to calculate the similarity or dissimilarity of the input vectors and the functional values are used to create a positive definite kernel matrix and reduced kernel matrix. Using a regularized least squares cost function the resulting optimization problem is expressed as a single unconstrained optimization problem which can be solved by matrix and/or iterative numerical methods. Advantages of this formulation include the explicit expressions used in the classification weights of the classifier(s) the model`s ability to incorporate several classes in a single formulation and to provide quick solutions to the optimal classification weights for multi-categorical separation and its ability to provide solutions without the use of specialized solver software. ····· 1036118224
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray We consider a Lorentz transformation in which the moving frame moves with uniform velocity in an arbitrary direction. Transformation matrix for such a transformation is found in the book of Misner et al and also that of Weinberg. We use this matrix to show that the volume element and a differential operator are invariant. We use these in turn to define other differential operators in an invariant manner. These operators are used in the study of electromagnetism. Another topic that may find application to topics in physical sciences is Irrotational vectorfields on a Surface in Euclidean space . It is shown that parallel surfaces preserve such a vectorfield and also that every real valued differentiable function on a sphere generates an irrotational vectorfield. A change of metric of a 2-dimensional Riemannian manifold leads to an invariant tensorfield, the vanishing of which leads to the conclusion that the geometrical object represented by the manifold is a torus. A parametric hyper-helicoid with Weierstrass type representation is another significant topic discussed in some detail. ····· 1036118047

Infinitesimals are infinitely small quantities, which in the words of Ber-noulli, are so small that `if a quantity is increased or decreased by an infinitesimal, then the quantity is neither increased nor decreased. Mathematicians approached the concept of infinitesimals with various methods, the Greek method of exhaustion, the method of indivisibles of the early modern ages, the geometry of indivisibles, the differentials of Leibnitz (that are intuitive infinitesimals). Their history is a synthesis of three parts, of philosophical, mathematical and physical part. In this book we will see some basic elements of these three stories. ····· 1036118023
