Dissemination of Information in Communication Networks

Series : Texts in Theoretical Computer Science. An EATCS Series

2004, Approx. 400 p., Hardcover
ISBN: 3-540-00846-2

About this textbook

With the rapid developments in hardware technologies, distributed computing and the interconnected world became realities, and the term "communication" became central in computer science. Solving communication tasks under different circumstances is the topic of this textbook. It provides an introduction to the theory of design and the analysis of algorithms for the dissemination of information in interconnection networks, with a special emphasis on broadcast and gossip. The book starts with the classic telegraph and telephone communication modes and follows the technology up to optical switches. Despite the rigorous presentation, simplicity and transparency are the main learning features of this book. All ideas, concepts, algorithms, analyses and arguments are first explained in an informal way in order to develop the right intuition, and then they are carefully specified in detail. This makes the content accessible for beginners as well as specialists.

Introduction.- Part I: The Telegraph and Telephone Modes: Fundamentals; Broadcasting; Gossiping; Systolic Communication; Fault-Tolerance.- Part II: Distributed Networks: Broadcast on Distributed Networks; Leader Election in Asynchronous Distributed Networks; Fault-Tolerant Broadcast in Distributed Networks.- References.- Index.

Grammatical Picture Generation
A Tree-Based Approach

Series : Texts in Theoretical Computer Science. An EATCS Series

2004, Approx. 420 p., with CD-ROM, Hardcover
ISBN: 3-540-21304-X

About this textbook

This book introduces the reader to the grammatical theory of picture generation, focussing on issues that are of particular interest for computer scientists. Using picture generation as a vehicle, many of the general ideas of the theory of computation are exemplified by results about (un)decidable, NP-complete, or efficiently solvable problems, normal forms, hierarchies of language classes, and related phenomena. Many of the devices and results discussed in the book extend those known from the literature, or are original ones, including a novel approach to generating colored pictures. The software on the enclosed CD-ROM lets you try out all examples or even extend the system.

Table of contents

Introduction.- Line Drawings.- Collage Grammars.- Iterated Function Systems.- Pictures in a Grid.- Languages of Fractals.- Colored Pictures.- TREEBAG.- Bibliography.- Index.

Statistical and Computational Inverse Problems

Series : Applied Mathematical Sciences , Vol. 160

2004, Approx. 310 p. 50 illus., Hardcover
ISBN: 0-387-22073-9

About this book

This book develops the statistical approach to inverse problems with an emphasis on modeling and computations. The framework is the Bayesian paradigm, where all variables are modeled as random variables, the randomness reflecting the degree of belief of their values, and the solution of the inverse problem is expressed in terms of probability densities. The book discusses in detail the construction of prior models, the measurement noise modeling and Bayesian estimation. Markov Chain Monte Carlo-methods as well as optimization methods are examples that are often non-trivial, but easy to follow. Besides the simple examples, the book contains problems as discretization errors, and statistical model reduction. Furthermore, the techniques are then applied to a number of real world applications such as limited angle tomography, image deblurring, electrical impedance tomography, and biomagnetic inverse problems. The book is intended for researchers and advanced students in applied mathematics, computational physics, and engineering. The first part of the book can be used as a textbook on advanced inverse problems courses.

Table of contents

Inverse Problems and Interpretations of Measurements.- Classical Regularization Methods.- Statistical Inversion Theory.- Nonstationary Inverse Problems.- Classical Methods Revisited.- Model Problems.- Case Studies.

Discrete-Time Markov Chains
Two-time-scale Methods and Applications

Series : Stochastic Modeling and Applied Probability, vol.55 ←Applications of Mathematics よりシリーズ名変更

2005, Approx. 365 p., Hardcover
ISBN: 0-387-21948-X

About this book

This book focuses on the theory and applications of discrete-time two-time-scale Markov chains. Much effort in this book is devoted to designing system models arising from these applications, analyzing them via analytic and probabilistic techniques, and developing feasible computational algorithms so as to reduce the inherent complexity. This book presents results including asymptotic expansions of probability vectors, structural properties of occupation measures, exponential bounds, aggregation and decomposition and associated limit processes, and interface of discrete-time and continuous-time systems. One of the salient features is that it contains a diverse range of applications on filtering, estimation, control, optimization, and Markov decision processes, and financial engineering. This book will be an important reference for researchers in the areas of applied probability, control theory, operations research, as well as for practitioners who use optimization techniques. Part of the book can also be used in a graduate course of applied probability, stochastic processes, and applications.

AN INTRODUCTION TO COMMUTATIVE ALGEBRA
From the Viewpoint of Normalization

Designed for a one-semester course in mathematics, this textbook presents a concise and practical introduction to commutative algebra in terms of normal (normalized) structure. It shows how the nature of commutative algebra has been used by both number theory and algebraic geometry. Many worked examples and a number of problem (with hints) can be found in the volume. It is also a convenient reference for researchers who use basic commutative algebra.

Contents:

Local Rings, DVRs, and Localization
Integral Extensions and Normalization
The Ring AK in K = ?(?)
Algebraic Geometry.

Readership: Graduate students in algebra and number theory.

DYNAMICS AND BIFURCATION OF PATTERNS IN DISSIPATIVE SYSTEMS

Understanding the spontaneous formation and dynamics of spatiotemporal patterns in dissipative nonequilibrium systems is one of the major challenges in nonlinear science. This collection of expository papers and advanced research articles, written by leading experts, provides an overview of the state of the art. The topics include new approaches to the mathematical characterization of spatiotemporal complexity, with special emphasis on the role of symmetry, as well as analysis and experiments of patterns in a remarkable variety of applied fields such as magnetoconvection, liquid crystals, granular media, Faraday waves, multiscale biological patterns, visual hallucinations, and biological pacemakers. The unitary presentations, guiding the reader from basic fundamental concepts to the most recent research results on each of the themes, make the book suitable for a wide audience.

WOODS HOLE MATHEMATICS
Perspectives in Mathematics and Physics

Series on Knots and Everything

The central theme of this volume is the contemporary mathematics of geometry and physics, but the work also discusses the problem of the secondary structure of proteins, and an overview of arc complexes with proposed applications to macromolecular folding is given.
“Woods Hole has played such a vital role in both my mathematical and personal life that it is a great pleasure to see the mathematical tradition of the 1964 meeting resurrected forty years later and, as this volume shows, resurrected with new vigor and hopefully on a regular basis. I therefore consider it a signal honor to have been asked to introduce this volume with a few reminiscences of that meeting forty years ago.” Introduction by R Bott (Wolf Prize Winner, 2000).
