This book integrates concepts from physical acoustics with those from linear viscoelasticity and fractional linear viscoelasticity. Compressional waves and shear waves in applications such as medical ultrasound, elastography, and sediment acoustics often follow power law attenuation and dispersion laws that cannot be described with classical viscous and relaxation models. This is accompanied by temporal power laws rather than the temporal exponential responses of classical models. The book starts by reformulating the classical models of acoustics in terms of standard models from linear elasticity. Then, non-classical loss models that follow power laws and which are expressed via convolution models and fractional derivatives are covered in depth. In addition, parallels are drawn to electromagnetic waves in complex dielectric media. The book also contains historical vignettes and important side notes about the validity of central questions. While addressed primarily to physicists and engineers working in the field of acoustics, this expert monograph will also be of interest to mathematicians, mathematical physicists, and geophysicists.
This book explains how the Columbia model of sociology, which was based on the methodology of P.F. Lazarsfeld, became a dominant sociological school of thought in American and European postwar sociology. Providing an overview of Lazarsfeld’s inventions and his methodological, organisational, and institutional innovations, it describes the means by which a particular model of sociology was gradually adopted in departments headed by Lazarsfeld and in the work of his successors. With attention to the use by Lazarsfeld of methodological texts published by prestigious publishing houses in his research and teaching, his activity in international organisations – including the UN – his collaboration with figures such as Robert K. Merton and Raymond Boudon, and his attempts to show how the roots of his empirical research methodology lay in the work of early European scholars, this volume shows how a particular sociological paradigm came to prevail over others for more than a decade. It will therefore appeal to scholars of sociology with interests in the history of the discipline and questions of research methodology.
The International Symposium of Acoustical Imaging has been widely recognized as the premier forum for presentations of advanced research result in both theoretical and experimental development. Held regularly since 1968, the symposium brings together international leading researchers in the area of acoustical imaging. The proceedings from the 25th meeting contains articles on the following topics: Mathematics and Physics of Acoustical Imaging, Transducers and Arrays, Nondestructive Evaluation, Geophysical and Underwater Ultrasonics, Microscopy and Microscanning, Scattering by Blood and Tissue, Medical and Biological Image Formation, Tissue Characterization, Tissue and Motion and Blood Flow, Elasticity Imaging, Hard Tissues, and Novel and Emerging Methods.
As the title of the book indicates, this is primarily a book on partial differential equations (PDEs) with two definite slants: toward inverse problems and to the inclusion of fractional derivatives. The standard paradigm, or direct problem, is to take a PDE, including all coefficients and initial/boundary conditions, and to determine the solution. The inverse problem reverses this approach asking what information about coefficients of the model can be obtained from partial information on the solution. Answering this question requires knowledge of the underlying physical model, including the exact dependence on material parameters. The last feature of the approach taken by the authors is the...
In this book, we present a dozen state of the art developments for ultrasound imaging, for example, hardware implementation, transducer, beamforming, signal processing, measurement of elasticity and diagnosis. The editors would like to thank all the chapter authors, who focused on the publication of this book.
Originally published in English in 1962, this book presents in clear language an account of the growth of sociology from its earliest roots in the Enlightenment, through the 19th century philosophers in Germany, positivists in France, social workers in England, the theorists in America, through the pioneering days of the early and middle part of the 20th century.
This book provides a comprehensive understanding of how intelligent data-driven techniques can be used for modelling, controlling, and optimizing various power and energy applications. It aims to develop multiple data-driven models for forecasting renewable energy sources and to interpret the benefits of these techniques in line with first-principles modelling approaches. By doing so, the book aims to stimulate deep insights into computational intelligence approaches in data-driven models and to promote their potential applications in the power and energy sectors. Its key features include: an exclusive section on essential preprocessing approaches for the data-driven model a detailed overvie...
Atherosclerosis is a subject of enormous contention for cardiologists and in general for all medical doctors. With this publication we have given you a concise "state-of-the-art" look at the world of atheroma. Many other elements could be included and so it is only a brief analysis of "today" (the preventive medicine era) and "tomorrow" (transforming the cure medicine era into the care medicine era) but also remembering "yesterday" (the ex-cathedra medicine era). Let's hope our arteries are free from atherosclerotic events: have a good read!
