Recently, criterion functions based on information theoretic measures (entropy, mutual information, information divergence) have attracted attention and become an emerging area of study in signal processing and system identification domain. This book presents a systematic framework for system identification and information processing, investigating system identification from an information theory point of view. The book is divided into six chapters, which cover the information needed to understand the theory and application of system parameter identification. The authors'' research provides a base for the book, but it incorporates the results from the latest international research publications.- Named a 2013 Notable Computer Book for Information Systems by Computing Reviews- One of the first books to present system parameter identification with information theoretic criteria so readers can track the latest developments- Contains numerous illustrative examples to help the reader grasp basic methods

Multigrid Finite Element Methods for Electromagnetic Field ModelingThis is the first comprehensive monograph that features state-of-the-art multigrid methods for enhancing the modeling versatility, numerical robustness, and computational efficiency of one of the most popular classes of numerical electromagnetic field modeling methods: the method of finite elements. The focus of the publication is the development of robust preconditioners for the iterative solution of electromagnetic field boundary value problems (BVPs) discretized by means of finite methods.Specifically, the authors set forth their own successful attempts to utilize concepts from multigrid and multilevel methods for the effective preconditioning of matrices resulting from the approximation of electromagnetic BVPs using finite methods. Following the authors' careful explanations and step-by-step instruction, readers can duplicate the authors' results and take advantage of today's state-of-the-art multigrid/multilevel preconditioners for finite element-based iterative electromagnetic field solvers.Among the highlights of coverage are: Application of multigrid, multilevel, and hybrid multigrid/multilevel preconditioners to electromagnetic scattering and radiation problemsBroadband, robust numerical modeling of passive microwave components and circuitsRobust, finite element-based modal analysis of electromagnetic waveguides and cavitiesApplication of Krylov subspace-based methodologies for reduced-order macromodeling of electromagnetic devices and systemsFinite element modeling of electromagnetic waves in periodic structuresThe authors provide more than thirty detailed algorithms alongside pseudo-codes to assist readers with practical computer implementation. In addition, each chapter includes an applications section with helpful numerical examples that validate the authors' methodologies and demonstrate their computational efficiency and robustness.This groundbreaking book, with its coverage of an exciting new enabling computer-aided design technology, is an essential reference for computer programmers, designers, and engineers, as well as graduate students in engineering and applied physics.

This book explores how population mobility varies among the countries of Asia. While much attention has been given to international migration, movement within countries is numerically much more significant. Coupling innovative methods developed in the global IMAGE project with the contextual knowledge of experts on 15 Asian countries, the book measures and explains how people across Asia differ in the probability of changing residence, the ages at which they move, and the impact of these migrations on the distribution of human settlement within each country. It demonstrates how stage of economic development, coupled with historical events, local contingencies, cultural norms, political frameworks, and the physical environment shape human migration. By using rigorous statistics in a robust comparative framework, this book provides a clear understanding of contemporary migration in Asia for students and academics, and a valuable resource for policy-makers and planners in Asia andbeyond.
