~~212,00€~~ 190,80€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 Fractional differential equations (FDEs), owing to their modeling potential in different branches of science and engineering, are attracting the attention of researchers. The concept of a fractional derivative is an extension of the classical derivative to a non-integer order derivative. Various types of fractional derivatives have been introduced, each being a generalization of an earlier version or having a certain advantage in a particular application. The present book consists of seven chapters selected to represent some of the current research trends in the area of fractional differential equations. The first two chapters present overviews of the stability theory of fractional differential equations and fractional-order difference equations, respectively. The next two chapters review existence results for two-point boundary value problems of nabla fractional difference equations and impulsive FDEs with variable moments of impulse, respectively. Chapter 5 introduces finite difference schemes for fractional diffusion equations. The tempered -Hilfer fractional derivative is used in Chapter 6 to study fuzzy random functional integro-differential equations. Chapter 7 deals with applications in FDEs of quantum-symmetric differential operators formulated via Raina functions.

J-Shaped Distributions And Their Applications

de Mohammad Ahsanullah

125,88€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 In many fields of research, such as, biology, computer science, control theory, economics, engineering, genetics, hydrology, medicine, number theory, statistics, physics, psychology, reliability, risk management, etc., the shapes of probability distributions of non-normal data exhibit J-shaped distributions. The shapes of such distributions may be skewed to the left or the right depending on whether a large percentage of data is at the lower or upper extreme. In this book, we have studied the J-shaped distributions and their applications. As a motivation, we have discussed several real-world examples which can be modeled through J-shaped distribution. We have presented the mathematical formulation of the family of J-shaped probability distributions which was first proposed by Topp and Leone (1955). We also have discussed several variations of Topp-Leone’s family of J-shaped distribution. We have considered the general form of J-shaped distribution and derived its moments independently. We also have discussed other distributional properties of the J-shaped distribution. Some distributional properties of order statistics of the J-shaped distribution such as moment, variance, product moments, and covariance are also provided. To describe the shapes of the J-shaped distribution, the plots of the and for various values of the parameter have been provided. Entropy provides an excellent tool to quantify the amount of information (or uncertainty) contained in a random observation regarding its parent distribution (population). A large value of entropy implies greater uncertainty in the data. As such, Shannon entropy of the J-shaped distribution is provided. The distributional properties of order statistics of the J-shaped distribution such as moment, variance, product moments, and covariance, have also been presented. The numerical computations of these for selected values of the parameters are provided. The distributional properties of the record values of the J-shaped distribution are also investigated. Some discussions on the sum, product and ratio of the J-shaped distributions are provided. Characterizations of the J-shaped distribution are given by using the method of truncated moment, order statistics and record values.

Students who learn about computational techniques in other courses subsequently realize the scope of partial differential equations beyond paper and pencil. Our book is significantly different from the existing ones. We introduce both analytical theory, including the theory of classical solutions and that of weak solutions, and introductory techniques of ill-posed problems with reference to weak solutions. Besides, since computational techniques are commonly available and are currently used in all practical applications of partial differential equations, we incorporate classical finite difference methods and finite element methods in our book.
