This volume presents a unified approach to constructing iterative methods for solving irregular operator equations and provides rigorous theoretical analysis for several classes of these methods. The analysis of methods includes convergence theorems as well as necessary and sufficient conditions for their convergence at a given rate. The principal groups of methods studied in the book are iterative processes based on the technique of universal linear approximations, stable gradient-type processes, and methods of stable continuous approximations. Compared to existing monographs and...

State-of-the-Art Approaches to Advance the Large-Scale Green Computing Movement

Edited by one of the founders and lead investigator of the Green500 list, The Green Computing Book: Tackling Energy Efficiency at Large Scale explores seminal research in large-scale green computing. It begins with low-level, hardware-based approaches and then traverses up the software stack with increasingly higher-level, software-based approaches.

In the first chapter, the IBM Blue Gene team illustrates how to improve the energy efficiency of a...

Although the particle swarm optimisation (PSO) algorithm requires relatively few parameters and is computationally simple and easy to implement, it is not a globally convergent algorithm. In Particle Swarm Optimisation: Classical and Quantum Perspectives, the authors introduce their concept of quantum-behaved particles inspired by quantum mechanics, which leads to the quantum-behaved particle swarm optimisation (QPSO) algorithm. This globally convergent algorithm has fewer parameters, a faster convergence rate, and stronger searchability for complex problems.

Idealer Einstieg: Theorie und Praxis paralleler numerischer Verfahren anhand klassischer Algorithmen. Dargestellt sind Bereiche der numerischen linearen Algebra als auch der numerischen Analysis. Bei Aufbau und Erstellung paralleler Programme hilft die Programmbibliothek MPI. Anhand der Praktikumsaufgaben konnen Leser ihren Lernerfolg uberprufen. Quelltexte sind auf der Homepage der Autoren zu finden. Ein praxisorientiertes Lehr- und Ubungsbuch fur Mathematiker, Informatiker, Ingenieurwissenschaftler.

Gegenstand des Buches sind Algorithmen zur Losung gangiger Fragestellungen der Analysis und der Linearen Algebra. Die Gliederung erfolgt anhand der mathematischen Objekte, die in den vorgestellten Methoden die zentrale Rolle spielen. So stehen im vorliegenden Buch Zahlen, Vektoren und univariate Polynome im Mittelpunkt, wahrend in einem nachfolgenden Band auf Algorithmen zu Matrizen, Funktionen und multivariaten Polynomen eingegangen wird. Nach einer Wiederholung der mathematischen Grundlagen stehen Entwicklung und Computerrealisierung der Losungsmethoden im Vordergrund.

"Numerik," in zwei Banden, ist eine Einfuhrung in die Numerische Mathematik anhand von Differenzialgleichungsproblemen. Gegliedert nach elliptischen, parabolischen und hyperbolischen Differenzialgleichungen, erlautert sie zunachst jeweils die Diskretisierung solcher Probleme. Als Diskretisierungstechniken stehen Finite-Elemente-Methoden im Raum und (partitionierte) Runge-Kutta-Methoden in der Zeit im Vordergrund. Die diskretisierten Gleichungen motivieren die Diskussion von Methoden fur endlichdimensionale (nicht)lineare Gleichungen, die anschliessend als eigenstandige Themen behandelt...

With an emphasis on problem solving, this book introduces the basic principles and fundamental concepts of computational modeling. It emphasizes reasoning and conceptualizing problems, the elementary mathematical modeling, and the implementation using computing concepts and principles. Examples are included that demonstrate the computation and visualization of the implemented models.

The author provides case studies, along with an overview of computational models and their development. The first part of the text presents the basic concepts of models and techniques for...

This book is about adaptive mesh generation and moving mesh methods for the numerical solution of time-dependent partial differential equations. It presents a general framework and theory for adaptive mesh generation and gives a comprehensive treatment of moving mesh methods and their basic components, along with their application for a number of nontrivial physical problems. Many explicit examples with computed figures illustrate the various methods and the effects of parameter choices for those methods. Graduate students, researchers and practitioners working in this area will benefit...

What makes this book stand out from the competition is that it is more computational. Once done with both volumes, readers will have the tools to attack a wider variety of problems than those worked out in the competitors' books. The author stresses the use of technology throughout the text, allowing students to utilize it as much as possible.

ECMI has a brand name in Industrial Mathematics and organises successful biannual conferences. This time, the conference on Industrial Mathematics held in Eindhoven in June 2004 Mathematics focused on Aerospace, Electronic Industry, Chemical Technology, Life Sciences, Materials, Geophysics, Financial Mathematics and Water flow. The majority of the invited talks on these topics can be found in these proceedings. Apart from these lectures, a large number of contributed papers and minisymposium papers are included here. They give an interesting (and impressive) overview of the important place...
