El análisis epistemológico muestra el surgimiento de la noción de variabilidad , como un conocimiento asociado y poco conocido del concepto de función, a lo largo del Siglo XIX. La componente cognitiva destaca las concepciones de los profesores, ampliamente influenciados por los libros de texto y planes de estudio. Demostramos que es posible la aplicación de esta teoría para el rescate de las concepciones que se tienen de un concepto matemático y utilizar el modelo para la transformación de una representación, adaptándolo al diseño de una situación de aprendizaje en la que se toman en cuenta tanto las representaciones, como el análisis preliminar al rescatar un concepto que se ha perdido en la propia evolución de la enseñanza o que no es tomado como eje principal para la construcción de esta noción. ····· 10361137238

Para analizar la categorización mencionada se convino en reinterpretar la acepción de gráfica como una practica establecida por Roth & McGuinn (1997), donde la gráfica es tratada como un objeto retórico para resignificar situaciones propias de la ingeniería.

Dos años después Chvátal presentó una solución a este problema. El propuso que si un galería de arte puede representarse a través de un polígono simple con n vértices, entonces n/3 guardias son siempre suficientes y a veces necesarios para vigilar el interior de la galería de arte. Este resultado atrajo la atención de investigadores en geometría computacional y combinatoria dando como resultado una colección de variantes de este problema y soluciones. Por ejemplo, guardias móviles o con restringida amplitud de visión o si la galería de arte puede representarse a través de un polígono ortogonal o un polígono simple con hoyos o un poliedro ortogonal entre otras variantes.

We have made an extensive study of operators like Ruscheweyh operator D_f(z), S al agean operator Dnf(z), Al-Oboudi generalized S al agean operator Dn_ f(z) and the operator _f(z) defined by using the fractional derivative D_ zf(z). In recent years, there have been many papers in which several subclasses are defined using these operators. These operators help to unify many well known classes of analytic functions and to obtain generalized results. We study several properties of functions of these classes thereby giving a unified approach to proving and at the same time generalizing many results that have been obtained earlier in literature. An attempt has been made to have a detailed study by employing different techniques. ····· 10361135826

By lacunary interpolation we mean to study an interpolation process when non consecutive derivatives are prescribed on a given set of nodes. Here we have considered the existence, uniqueness, explicit representation of a modified weighted (0, 1, 3) and (0, 1, 2, , r - 2, r) interpolations on an arbitrary set of nodes, weighted (0, 2), (0, 1, 3) interpolations on the zeros of nth-Hermite polynomial and a mixed type (0 0, 2) interpolation when function values and weighted (0, 2) are prescribed on the zeros of nth-Hermite polynomials and its derivative respectively. A convergence theorem has been obtained in these cases. The results obtained here are better to some earlier results obtained by several mathematicians in the sense that (i) an artificial looking condition, used for obtaining the explicit representation of the fundamental polynomials, has been replaced by a simple interpolatory condition (ii) the results have been obtained in the case when n is considered to be odd and (iii) an improved quantitative estimate of the interpolatory polynomials has been obtained. ····· 10361135746
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Alternative to the least square coefficient of determination, R-squared OLS, the coefficient of determination based on median absolute deviation, R-squared MAD, is an attractive consideration in the construction of goodness-of-fit test based on regression and correlation, due to its robustness. This book focused on the observations made from the resulting plots and descriptive measures obtained from contaminated standard logistic distribution. Contamination is introduced to investigate perseverance of robustness property of R-squared MAD for samples from the standard logistic distribution. The early section of the book is devoted to the investigation of the symmetricity of the sampling distribution of R-squared MAD and its confidence intervals in the presence of outliers. This is followed by constructing tables of critical values for samples from the standard logistic distribution. Then a power study on the goodness-of-fit test using test statistic ZMAD and ZOLS is conducted via simulation. The results indicated that the test statistic ZMAD is able to discriminate the sample that comes from alternative distributions as the test statistic ZOLS. ····· 10361135492
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The method of layer potentials is one of the classical approaches to solving boundary value problems for (strongly) elliptic equations. This method reduces the original problem to that of inverting an operator of the form `1/2 +K` on appropriate boundary function spaces. Recently, this method has attacted considerable attention both in the theoretical and the applied mathematics. This dissertation deals with the method of layer potentials on domains with conical points from a groupoid point of view. By a desingularization process and integration of a Lie algebroid, we can construct a Lie groupoid that encodes the geometry and singularities of this domain. Then we identify the double layer potential operator K with an invariant family of that Lie groupoid. From this, we can obtain the Fredholmness of the operator `1/2+K`. ····· 10361134574
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Exact solutions to nonlinear evolution equations (NEEs) play an important role in nonlinear physical science, since the characteristics of these solutions may well simulate real-life physical phenomena. One of the benefits of finding new exact solutions to such nonlinear partial differential equations (PDEs) is to give a better understanding on the various characteristics of the solutions. The main task of this work is to show that our proposed methods, improved tanh and sech methods, are very efficient in solving various types of NEEs and PDEs including special equations than using classical tanh and sech methods. This efficiency is because of their rich with the multiple traveling wave solutions than classical tanh and sech methods. From the obtained results, we can not only recover the previous solutions obtained by some authors but also obtain some new and more general solitary wave, singular solitary wave and periodic solutions. Illustrating the theory of nonlinear transmission lines (NLTLs), showing the ability of NLTL to generate solitons and solving the model equation of NLTL in presence of loss are other tasks of this book. ····· 10361134531
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Long before the Global Financial Crisis in the late-2000s, many academics and professionals were discussing the adequacy of using so called Gaussian copula models to evaluate the risk of collateralized debt obligations (CDOs). Many of them pointed out that such models are too simplifying the complicated correlation structure of portfolios. Indeed, this was afterwards identified as one of the key factors spreading the crisis. In this book, we would like to introduce the basic mathematical theory of the copula-based portfolio credit risk models and some of their generalizations. We start by introducing the terms of probability of default and expected loss, as well as some common obligor models. Then we give an example of a duo basket model, followed by mathematical definitions of copulas and various dependence measures. Finally, we focus on threshold models and their limit behavior for the number of loans going to infinity.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book presents applications of the methods known as renormalization group (RG) and scaling in the physics literature to applied mathematics problems after a brief review of the methodology. The first part involves an application to a class of nonlinear parabolic differential equations. First, RG methods are described for determining the key exponents related to the decay of solutions to these equations. The determination of decay exponents is viewed as an asymptotically self similar process that facilitates an RG approach. The methods are also extended to higher order in the small coefficient of the nonlinearity. Finally, the RG results are verified in some cases by rigorous proofs and other calculations. In the second part, the application of RG technique to systems of equations describing interface problems is presented. The temporal evaluation of an interface separating two phases is analyzed for large time. The standard sharp interface problem in the quasi-static limit is studied. The characteristic length of a self-similar system that is a time dependent length scale characterizing the pattern growth is calculated by implementing RG procedure. ····· 10361134166

This sequence of integers counts a variety of combinatorial objects including binary trees and triangulations of regular polygons. Of the hundreds of realizations of the Catalan numbers, the majority can be extended and considered under the scope of the generalized Catalan numbers. The generalized Catalan numbers consider a second parameter in addition to the parameter of the regular Catalan numbers, consequently forming a grid of values instead of a sequence of integers. Although a formula has been developed to determine the generalized Catalan number when given values for the parameters, much is still unknown about the generalized Catalan numbers. This thesis will count the generalized Catalan orbits, defined to be the orbits of the combinatorial objects counted by the generalized Catalan numbers. Two realizations of the generalized Catalan numbers, p-ary trees and the dissection of regular polygons, will be used throughout the study of the generalized Catalan orbits. A variety of techniques will be used to create formulas which describe the number of generalized Catalan orbits in terms of the given parameters. ····· 10361133978

ML is the process of training a system with large number of examples, extracting rules and finding patterns in order to make predictions on new data points (examples). As a first motivation, we develop a model selection tool induced into SVM in order to solve a particular problem of computational biology which is prediction of eukaryotic pro-peptide cleavage site applied on the real data collected from NCBI data bank. Based on our biological example, a generalized model selection method is employed as a generalization for all kinds of learning problems. As the data become heterogeneous and large-scale, single kernel methods become insufficient to classify nonlinear data. Convex combinations of kernels were developed to classify this kind of data. Nevertheless, selection of the finite combinations of kernels are limited up to a finite choice. In order to overcome this discrepancy, we propose a novel method of infinite kernel combinations for learning problems with the help of infinite and semi-infinite programming. ····· 10361133954

Turbulence is observed in natural and engineering applications such as in weather prediction, air pollution, water pollution, aerodynamics and heat exchangers. This work considers an accurate and reliable solutions of turbulent flows. It is concerned with one of the most promising approaches to the numerical simulation of turbulent flows, the subgrid eddy viscosity models. We analyze both continuous and discontinuous finite element approximation of the new subgrid eddy viscosity model. This approach has the advantage that the diffusivity is introduced only on the small scales of the flow.

It is an automatic and vital process that moves food through the digestive tract, urine from the kidneys through the ureters into the bladder, and bile from the gallbladder into the duodenum. The transport phenomenon created by peristalsis is an interesting problem because of its application in understanding many physiological transport processes through vessels under peristaltic motion. Roller and finger pumps using viscous fluids also operate on this principle. Here the tube is passive but is compressed by rotating rollers, by a series of mechanical fingers or by a notating plate.Many researchers considered the fluid to behave like a Newtonian fluid for physiological peristalsis including the flow of blood in arterioles.Flow through a porous medium has been of significant interest in recent years particularly among geophysical fluid dynamics.
