Noise mapping is the first tool to effectively assess noise exposure, communicating information to citizens, and defining effective action plans for protecting citizens from high noise levels and preserving quiet areas in urban European Community environments. Indeed, strategic noise maps are now required in the European Union for all population centers of more than 250,000 inhabitants, as well as for major roads, railways, and airports, and are becoming required for urban areas with over 100,000 people. Providing a comprehensive reference guide for students, researchers, acoustics consultants, and environmental agencies, Noise Mapping in the EU: Models and Procedures shows how to integrate data with geographical information systems, improve accuracy in model and prediction software, and assess different methods and descriptors for evaluating annoyance and noise exposure. It offers guidance on regulations, communication processes, physical aspects, and application of noise mapping, as well as on communication processes for citizens involved in decision making. Beginning with fundamental concepts in acoustics and a presentation of legal frameworks for noise mapping in Europe, the book covers all the main issues about noise mapping. It presents numerical models for roads, railways, airports, harbours, and industrial sites. The chapters are written by European experts from a range of research institutes, companies, and environmental agencies. Using a practical approach and worked examples, the text discusses control and uncertainty in input data and output results, technical recommendations from working groups, and the Good Practice Guide (GPG) tool. It provides in-depth coverage of geographic information system (GIS) techniques for noise management and the evaluation and management of noise exposure, and concludes by reviewing noise mapping experiences in Europe, communication to the public, and future perspectives for mapping the effects of noise.

What is this sound? What does that sound indicate? These are two questions frequently heard in daily conversation. Sound results from the vibrations of elastic media and in daily life provides informative signals of events happening in the surrounding environment. In interpreting auditory sensations, the human ear seems particularly good at extracting the signal signatures from sound waves. Although exploring auditory processing schemes may be beyond our capabilities, source signature analysis is a very attractive area in which signal-processing schemes can be developed using mathematical expressions. This book is inspired by such processing schemes and is oriented to signature analysis of waveforms. Most of the examples in the book are taken from data of sound and vibrations; however, the methods and theories are mostly formulated using mathematical expressions rather than by acoustical interpretation. This book might therefore be attractive and informative for scientists, engineers, researchers, and graduate students who are interested in the mathematical representation of signals and the applications of Fourier analysis. The book can be described as being practically self-contained but does assume readers are familiar with introductory topics in discrete signal processing, as in the discrete Fourier transform. Hence this book might be also usable as a textbook in graduate courses in applied mathematics on topics such as complex functions. Almost all scientific phenomena are sensed as waves propagating in some space. Over the years, waveform analysis has therefore been one of the resilient academic areas of study and still is seen as fertile ground for development. In particular, waveform analysis based on the theory of linear systems would be a good example where a physical interpretation can be given to the mathematical theory of complex functions in terms of magnitude, angle, poles, and zeros of complex functions. For readers who are interested in the physical aspects of sound and vibration data or elementary formulation of wave equations and their solutions, the book Sound and Signals by M. Tohyama (Springer 2011) is recommended. It can serve as a complementary companion to this present volume or independently as a good reference.

This book offers a mathematical update of the state of the art of the research in the field of mathematical and numerical models of the circulatory system. It is structured into different chapters, written by outstanding experts in the field. Many fundamental issues are considered, such as: the mathematical representation of vascular geometries extracted from medical images, modelling blood rheology and the complex multilayer structure of the vascular tissue, and its possible pathologies, the mechanical and chemical interaction between blood and vascular walls, and the different scales coupling local and systemic dynamics. All of these topics introduce challenging mathematical and numerical problems, demanding for advanced analysis and efficient simulation techniques, and pay constant attention to applications of relevant clinical interest. This book is addressed to graduate students and researchers in the field of bioengineering, applied mathematics and medicine, wishing to engage themselves in the fascinating task of modeling the cardiovascular system or, more broadly, physiological flows.

Markov random field (MRF) modeling provides a basis for the characterization of contextual constraints on visual interpretation and enables us to develop optimal vision algorithms systematically based on sound principles. This book presents a comprehensive study on using MRFs to solve computer vision problems, covering the following parts essential to the subject: introduction to fundamental theories, formulations of various vision models in the MRF framework, MRF parameter estimation, and optimization algorithms. Various MRF vision models are presented in a unified form, including image restoration and reconstruction, edge and region segmentation, texture, stereo and motion, object matching and recognition, and pose estimation. This book is an excellent reference for researchers working in computer vision, image processing, pattern recognition and applications of MRFs. It is also suitable as a text for advanced courses in the subject.
