The aim of this thesis is to introduce and study some chaotic complex nonlinear dynamical systems, for example, complex Chen and Lü systems . There are interesting cases of dynamical systems, where the main variables participating in the dynamics are complex, for example, when amplitudes of electromagnetic fields of laser systems are involved. Another example is when chaos synchronization is used for communications, where doubling the number of variables may be used to increase the content and security of the transmitted information. This monograph is mainly addressed to graduate students and senior researchers interested in the study of complex nonlinear systems. ····· 10361101857

The ill-posedness of the problem is taken into account. First a Fredholm equation is regularized. Then it is transformed to a differential equation in the case where the time interval is {bf R}. A fast algorithm to solve the differential equation by the finite differences is given and a regularized spectral estimation formula is obtained. Then a regularized iterative extrapolation algorithm is introduced and compared with the Papoulis and Gerchberg algorithm. A time-frequency regularized extrapolation algorithm is presented in the two-dimensional case. The Gibbs phenomenon is analyzed. Then the time-frequency regularized extrapolation algorithm is applied to image restoration and compared with other algorithms. ····· 10361101835
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book presents a global bifurcation study of a four-dimensional system of differential equations modeling the Rayleigh-Bernard convection. The Rayleigh and Prandtl numbers are two natural parameters on which the system depends. The investigation of the model proceeds through a combination of theoretical analysis and numerical computations. There are local bifurcations, corresponding to changes in stability of steady patterns, but the main changes are governed by curves of global bifurcations involving homoclinic and heteroclinic dynamics. A numerical investigation identifies codimension-two global bifurcations that organize the bifurcation diagram. Bifurcation analysis makes clear the unfolding of these bifurcations. The book is extracted from the doctoral thesis to the Unviversity of Amsterdam, under supervision of Dr. Ale Jan Homburg. ····· 10361101771
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The topics of this book are dynamical behaviour of a class of discontinuous maps including piecewise linear maps on the 2-torus and planar piecewise isometries, some preliminary symbolic dynamics approach to these maps, and some aspects of symbolic dynamics itself. At first, a class of piecewise linear parabolic maps on the torus are discussed. Then some area-preserving piecewise linear discontinuous maps of the plane are examined. Symbolic descriptions of the dynamics and admissibility conditions for itineraries of a class of linear maps on the 2-torus and some planar piecewise isometries are discussed. For the symbolic dynamical system itself, scrambled sets of shift maps are discussed, and some problems related to maximal scrambled sets are also discussed. For the subshifts generated by the orbit closures of certain non-periodic recurrent points, their chaotic properties are investigated. Moreover, a general and systematic discussion of various symbolic representations of iterated maps through subshifts are presented, and examples of partitions and representations of some discontinuous maps are given. ····· 10361101599
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Calculus is a get way to higher order mathematics. In most countries calculus is introduced as a process involving infinitely many steps which is a paradigm shift to students as their pre-calculus concept involves finite logical steps to solve a problem. This book consist the study examining students difficulties and misconceptions in learning concepts of calculus at preparatory secondary schools. Accordingly, students conception of concepts in calculus, students misconceptions, and factors influencing the teaching-learning of concepts were surveyed. Documentaries, classroom observation, and achievement test were the instruments used for gathering the necessary data.The book has a potential benefit to mathematics teachers in that it provides them information about their students possible misconceptions. Over generalizing a limit just as a function value, the perception that a function must be defined at a point to have a limit at that point, and that a discontinuous function must have an asymptote were identified as misconceptions students have formed. ····· 10361101559
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Fuzzy Topographic Topological Mapping (FTTM) is a model for solving neuromagnetic inverse problem. FTTM consists of four topological spaces which are connected by three homeomorphisms. FTTM 1 and FTTM 2 were designed to present 3-D view of an unbounded single current and bounded multicurrent sources, respectively. It has been showed that FTTM 1 and FTTM 2 are homeomorphic and this homeomorphism will generate another 14 FTTM. There is a conjecture stated that if there exist n numbers of FTTM, then they will generate another new FTTM. In this book, the conjecture is proven by using geometrical features of FTTM. In the process, several definitions are developed. Some geometrical and algebraic properties of sequences of FTTM are identified and proven. A new conjecture is also proposed in this book. Surprisingly, the nonzero sequence of cube with combination of two, three and four FTTM appeared in Pascal s Triangle. ····· 10361101491

Also we present some known results and derive several new ones on the boundedness and the global stability of the solutions of the difference equation We study the global stability, the boundedness nature, and the periodic character of the positive solutions of the difference equation which is interesting in its own right, but which may also be viewed as describing a population model.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In this book the convergence of the multiscale finite element method (MsFEM) for second order elliptic equations with oscillating coefficient in two space dimension is studied. Such equations often arise in composite materials and flows in porous media. The main purpose is to understand the theoretical background of this method and its convergence analysis. The oscillating coefficient is assumed to be of two scales and is periodic in the large scale. The MsFEM is capable of correctly capturing the large scale components of the solution on a coarse grid without accurately resolving all the small scale features in the solution. This is accomplished by incorporating the local microstructure of the differential operator into the finite element base functions. As a consequence, the base functions are adapted to the local properties of the differential operator. ····· 10361101135

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray One of the main problems of quantitative study of proofs is speed-up phenomenon, that is a situation, where two systems are compared such that some theorems have much shorter proof in one of them. For the first time such problem on the proof steps was considered for arithmetical systems by Gödel. Now many results in this field are well-known. In all of them by comparison of two systems for every recursive function can be pointed one formula or infinite set of formula, which has speed-up. We introduce the common notion of proof complexity (by analogy to Blum computational complexity), the notion of ordinary theory and formulate some conditions for any pair of theory, which are enough for possibility of the most generalized (Rabin style) speed-up, i.e. for arbitrary general recursive function there exists n0 such that for every nn0 there is provable in both theories formula n such that its proof complexity in stronger theory is no more than n and in the weaker theory is greater than (n). Many pair systems with above conditions are considered as well as the constructive description of hard provable formulas for some pair systems is given. ····· 10361100988

In this work the method is presented by solving the axisymmetric Laplace`s equation. Later the Grad-Shafranov Equation(GSE) is solved by means of this powerful technique. The GSE is a simplification of ideal MHD in two dimensions. The resulting equation is a nonlinear, elliptic partial differential equation. The GBEM is well suited for solving this type of equations in `irregular domains` such as unbounded and irregular shape domains. ····· 10361100934
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book studies the performance of distributed detection systems by means of large deviation techniques under two distinct models. In the first model, the error performance is investigated as the number of sensors tends to infinity by assuming that the i.i.d. sensor data are quantized locally into m-ary messages and transmitted to the fusion center for binary hypothesis testing. It is found that when the second moment of the post-quantization log-likelihood ratio is unbounded, the Neyman-Pearson error exponent becomes a function of the test level whereas the Bayes error exponent remains unaffected. Also shown is that in Bayes testing, the equivalence of absolutely optimal and best identical-quantizer systems is not limited to error exponents but extends to the actual Bayes errors up to a multiplicative constant. In the second model, the null and alternative distributions become spatially correlated Gaussian, differing in the mean. The issue considered includes whether contiguous marginal likelihood ratio quantizers are optimal. It is shown that this is not true in general, and a sufficient condition is obtained under the case of a single observation per sensor. ····· 10361100746
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray A physical state in a domain is often described by a model containing a linear partial differential equation. As an example of this, consider the steady state temperature distribution in a homogenous isotropic body. The problem, called Dirichlet`s problem, is to find a function u, given that u=f in the interior of the body and u=g on the surface (where u denotes the laplacian of u). The solution depends on f and g, but also on the geometry of the surface S. If the given functions f and g, as well as the subset S of 3-space, are smooth enough, then there exists a unique solution. However, since there are numerous non-smooth structures in nature, it is clear that the study of Dirichlet`s problem in the case when f, g and S are less smooth becomes an important task. Function spaces defined on subsets of n-space originates from the study of Dirichlet`s problem in the non-smooth case of f, g and S. An important class of functions in this respect are Besov spaces, defined in n-space in the 60`s. In the 80`s Besov spaces were extended to d-sets, typically fractal sets with non-integer local dimension d. In this book we extend Besov space theory to sets with varying local dimension. ····· 10361100712

The work has been compiled in the form of seven chapters with each chapter focusing on the development of traffic flow model towards real world. Some qualitative properties together with linear stability analysis have been studied. Motivated by the importance of traffic modeling, in this book a series of flow situations to uncover some of the fundamental aspects of traffic flow are examined. Finite difference method is used as a tool to solve the governing system of highly nonlinear partial differential equations. Numerical solutions so obtained are analysed and interpreted physically. The results are displayed in form of graphs.

It can be considered as a counterpart of the study of the classical Euclidean elastic curves. The basic idea here is to replace the Euclidean space with an affine space. We try to develop some properties about the affine curve which is invariant under some specific subgroups of the affine groups A(2) and A(3). We consider the critial curves of the curvature energy functionals related to the affine curvature or centroaffine curvature of the nondegenerate curve or starlike curve repectively. We completely solve the motion equation by using the Jacobi elliptic functions and finally solve the structure equation by using Killing fields and the classification of the special linear group for the starlike curves. ····· 10361100262
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This work traces the development of the theory of types from its origins in the early 20th century through its various forms until the mid 1950s. Attention is paid to the reception of this theory after the publication of the second edition of Whitehead and Russell s `Principia Mathematica`. I examine the decline of the theory over four decades, focusing on its modification by logicians such as Ramsey, Carnap, Church, Quine, Gödel, and Tarski. Finally, the view of the theory of types as a many-sorted first-order theory is discussed. It is shown that a revival of the ramified theory of types in the 1950s coincided with the consideration of cumulative type hierarchies which substantially altered the form of the theory. The theory was altered even more drastically in its change from a many-sorted theory to a one-sorted theory. This final standardization made it not much different from first-order Zermelo-Fraenkel set-theory. The theory of types, whose developments are traced in this work, therefore lost its prominence as the foundation for mathematics and logic. This historical analysis will be of interest primarily to those working in the History and Philosophy of Mathematics. ····· 10361100250

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The growth of population, indiscriminate establishment of industries, auto-mobiles etc., are some of the major causes for the atmospheric pollution, besides power shortage. There is a growing concern that pollution together with accelerated growth and development of nations may alter the climate due to the release of large amount of soot, carbon emission and other pollutants into the atmosphere in the form of ultra-fine dust particles which are suspended in the atmosphere called aerosols. They play an important role in the atmospheric processes favouring cloud formation due to large size aerosols and having adverse effects on health, depending on their size due to coagulation process. This book focuses on mathematical modelling of dispersion of aerosols in the presence/absence of electric field and first order chemical reaction using different dispersion models. The problems addressed here are representative of aerosol removal mechanisms. In order to keep the environmental problems mathematically tractable few simplifying assumptions have been made to the extent that they do not obscure the actual phenomena which was purportedly modelled in a restrictive yet representative sense. ····· 1036199981· 1 · ::::: · 9 ·· 10 ·· 11 ·· 12 ·· 13 ·· 14 ·· 15 · ::::: · 29 ·
