Complex Methods for Partial Differential Equations

INTERNATIONAL SOCIETY FOR ANALYSIS, APPLICATIONS AND COMPUTATION Volume 5

The book contains review chapters as well as state-of-the-art research chapters on topics ranging from complex elliptic
first-order systems and second-order systems with regular or singular coefficients to overdetermined systems in several complex variables and partial differential equations in Clifford analysis.
Different boundary value problems are studied. Applications to crack problems in elasticity theory to cusped bars, plates, and
shells are given. Wavelet transformations are constructed in Banach spaces and used to identify complex analysis from the
viewpoint of geometry. Fixed-point problems, even in abstract Banach spaces, are investigated with respect to an optimal domain
of existence for the solution.

Audience: Researchers working in the field as well as scientists interested in the applications.

Semi-Markov Models and Applications

It is now clear that semi-Markov processes play an increasingly crucial role in business and industry; this is partially due to the fact that, with the powerful mathematical software now existing, the numerical treatment of basic integral equations is easier and so leads to more concrete applications; moreover the development of topics such as non-homogeneous models and statistical estimation make it possible to construct more adequate models of real-life problems and to calibrate the basic parameters of the models more accurately from real data.

This book presents many original models that are or could be truly useful for applications in real-life problems, and the editor hopes that it will contribute to the stimulation of new interactions between the theoretical development and the applications of
semi-Markov models.

Audience: This book should constitute a basic reference for researchers of this important field of stochastic modelling.

A Mathematical Structure for Emergent Computation

NONCONVEX OPTIMIZATION AND ITS APPLICATIONS Volume 36

An understanding of emergent computation requires a profound revision of the most fundamental ideas. A noticeable attempt of
such a rethinking is a world view in which natural systems are seen not as separate entities but as integrated parts of a unified whole.
The book for the first time presents such a mathematical structure, which remarkably is based on integers as the single
concept. As integers are considered to be the most fundamental entities irreducible to something simpler, this makes the
mathematical structure a final theory, and thus we do not have to look for its explanation in terms of deeper concepts. The book is not only applicable to models of computation and optimization but also has scientific consequences, as it contributes to a rethinking of the most fundamental ideas about nature.

Audience: The book is written at a level suitable for advanced undergraduate students and graduate students as well as research
workers and practitioners in computer science information technology, mathematics and physics. The book is suitable as a
reference or as supplementary reading material for an advanced graduate course. Only a basic knowledge of calculus is required.

Design Considerations of Time in Fuzzy Systems

APPLIED OPTIMIZATION Volume 35

This book is outstanding for several reasons: it observes the role of time in fuzzy proposition calculations, provides calculation error analysis for small density of inference processing and gives numerous examples of fuzzy sets and systems programming with time incorporated into a fuzzy inference machine based on MATLAB and Mathematica packages. Major contributions in the
field so far have only dealt with the JK fuzzy flip-flop; however, in this book the author covers analysis and simulation of various
memory devices such as Delay, Trigger, Set–Reset etc. Simulations of fuzzy memory modules built with given memory cells are also presented.

Audience: Readers from undergraduate to postgraduate level can comprehend the material of the book as it does not require
high-level mathematics, yet it covers the entire spectra of fuzzy sets and possibility logic as related to time.

Practical Applications of Fuzzy Technologies

THE HANDBOOKS OF FUZZY SETS Volume 6

Since the late 1980s, a large number of very user-friendly tools for fuzzy control, fuzzy expert systems, and fuzzy data analysis have emerged. This has changed the character of this area and started the area of `fuzzy technology'. The next large step in the
development occurred in 1992 when almost independently in Europe, Japan and the USA, the three areas of fuzzy technology,
artificial neural nets and genetic algorithms joined forces under the title of `computational intelligence' or `soft computing'. The
synergies which were possible between these three areas have been exploited very successfully.

Practical Applications of Fuzzy Sets focuses on model and real applications of fuzzy sets, and is structured into four major parts:
engineering and natural sciences; medicine; management; and behavioral, cognitive and social sciences. This book will be useful for practitioners of fuzzy technology, scientists and students who are looking for applications of their models and methods, for topics of their theses, and even for venture capitalists who look for attractive possibilities for investments.

Vector Variational Inequalities and Vector Equilibria
Mathematical Theories

NONCONVEX OPTIMIZATION AND ITS APPLICATIONS Volume 38

The book deals with the mathematical theory of vector variational inequalities with special reference to equilibrium problems. Such models have been introduced recently to study new problems from mechanics, structural engineering, networks, and industrial management, and to revisit old ones. The common feature of these problems is that given by the presence of concurrent objectives and by the difficulty of identifying a global functional (like energy) to be extremized. The vector variational inequalities have the advantage of both the variational ones and vector optimization which are found as special cases. Among several applications, the equilibrium flows on a network receive special attention.

Audience: The book is addressed to academic researchers as well as industrial ones, in the fields of mathematics, engineering,
mathematical programming, control theory, operations research, computer science, and economics.

Parallel Algorithms for Linear Models
Numerical Methods and Estimation Problems

ADVANCES IN COMPUTATIONAL ECONOMICS Volume 15

Parallel Algorithms for Linear Models provides a complete and detailed account of the design, analysis and implementation of
parallel algorithms for solving large-scale linear models. It investigates and presents efficient, numerically stable algorithms for
computing the least-squares estimators and other quantities of interest on massively parallel systems.

The monograph is in two parts. The first part consists of four chapters and deals with the computational aspects for solving
linear models that have applicability in diverse areas. The remaining two chapters form the second part, which concentrates on
numerical and computational methods for solving various problems associated with seemingly unrelated regression equations (SURE) and simultaneous equations models.

The practical issues of the parallel algorithms and the theoretical aspects of the numerical methods will be of interest to a broad
range of researchers working in the areas of numerical and computational methods in statistics and econometrics, parallel
numerical algorithms, parallel computing and numerical linear algebra. The aim of this monograph is to promote research in the
interface of econometrics, computational statistics, numerical linearalgebra and parallelism.
