Book Description
Excerpt from A d104book of Sound: Being an Account of the Physics of Vibrations With Special Reference to Recent Theoretical and Technical Developments In addition to the large extension of frequency-range, new apparatus and new methods of investigation have been introduced which have completely transformed all branches of the subject. The very important analogy existing between electrical and mechanical vibrating systems is now in general use. Not only are electrical methods extensively applied in the production and reception of mechanical vibrations, but the theory of one is closely interlinked with that of the other. The familiar con ceptions of electrical potential, current, and impedance are now applied with almost equal facility to mechanical systems; we have mechanical filters analogous to electrical filters, and complex mechanical vibrating systems (e.g. Such as a gramophone sound box or a 'loud speaker') are now designed in strict accordance with electrical principles. Electrical methods are extensively used also as a means of amplifying mechanical vibrations, the feeble effects at a sound-receiving surface being converted into electrical currents, amplified electrically and reproduced as mechanical vibrations of greatly increased intensity. It seems desirable that these and the many other important developments should be recorded side by side with the earlier work of Rayleigh and his followers. I have endeavoured to write the book in a manner suited to the requirements of university students, but it is hoped that it may also prove of some value to those interested in the more technical, or applied, aspects of the subject. For those requiring further information a plentiful supply of references to original papers is provided. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
In the 1980’s sonochemistry was considered to be a rather restricted branch of chemistry mainly involving the ways in which ultrasound could improve synthetic procedures, predominantly in heterogeneous systems and particularly for organometallic reactions. This volume traces the evolution of sonochemistry from a century ago when the effects of acoustic cavitation were first reported almost as a scientific curiosity, through the 1980’s to the present. It describes the ways in which scientific interest grew rapidly during the 1990’s with the formation of the European Society of Sonochemistry in 1990 and the launch of a new journal Ultrasonics Sonochemistry in 1994. It also includes two chapters relating to the evolution of the subject as seen through the particular experiences of the authors Tim Mason and Mircea Vinatoru, both pioneers of sonochemistry. One chapter is devoted to the ultrasonically assisted extraction (UAE) of chemicals from plant material. This also illustrates the different ways in which sonochemical technologies can be applied in both batch and flow systems leading to the development of large-scale processing. The other chapter relating to environmental protection shows the wide range of applications of sonochemistry in this important field for both biological and chemical decontamination.

Book Description
This book treats the mechanics of porous materials infiltrated with a fluid (poromechanics), focussing on its linear theory (poroelasticity). Porous materials from inanimate bodies such as sand, soil and rock, living bodies such as plant tissue, animal flesh, or man-made materials can look very different due to their different origins, but as readers will see, the underlying physical principles governing their mechanical behaviors can be the same, making this work relevant not only to engineers but also to scientists across other scientific disciplines. Readers will find discussions of physical phenomena including soil consolidation, land subsidence, slope stability, borehole failure, hydraulic fracturing, water wave and seabed interaction, earthquake aftershock, fluid injection induced seismicity and heat induced pore pressure spalling as well as discussions of seismoelectric and seismoelectromagnetic effects. The work also explores the biomechanics of cartilage, bone and blood vessels. Chapters present theory using an intuitive, phenomenological approach at the bulk continuum level, and a thermodynamics-based variational energy approach at the micromechanical level. The physical mechanisms covered extend from the quasi-static theory of poroelasticity to poroelastodynamics, poroviscoelasticity, porothermoelasticity, and porochemoelasticity. Closed form analytical solutions are derived in details. This book provides an excellent introduction to linear poroelasticity and is especially relevant to those involved in civil engineering, petroleum and reservoir engineering, rock mechanics, hydrology, geophysics, and biomechanics.

Book Description
Composites have been studied for more than 150 years, and interest in their properties has been growing. This classic volume provides the foundations for understanding a broad range of composite properties, including electrical, magnetic, electromagnetic, elastic and viscoelastic, piezoelectric, thermal, fluid flow through porous materials, thermoelectric, pyroelectric, magnetoelectric, and conduction in the presence of a magnetic field (Hall effect). Exact solutions of the PDEs in model geometries provide one avenue of understanding composites; other avenues include microstructure-independent exact relations satisfied by effective moduli, for which the general theory is reviewed; approximation formulae for effective moduli; and series expansions for the fields and effective moduli that are the basis of numerical methods for computing these fields and moduli. The range of properties that composites can exhibit can be explored either through the model geometries or through microstructure-independent bounds on the properties. These bounds are obtained through variational principles, analytic methods, and Hilbert space approaches. Most interesting is when the properties of the composite are unlike those of the constituent materials, and there has been an explosion of interest in such composites, now known as metamaterials. The Theory of Composites surveys these aspects, among others, and complements the new body of literature that has emerged since the book was written. It remains relevant today by providing historical background, a compendium of numerous results, and through elucidating many of the tools still used today in the analysis of composite properties. This book is intended for applied mathematicians, physicists, and electrical and mechanical engineers. It will also be of interest to graduate students.

Book Description
This newest edition adds new material to all chapters, especially in mathematical propagation models and special applications and inverse techniques. It has updated environmental-acoustic data in companion tables and core summary tables with the latest underwater acoustic propagation, noise, reverberation, and sonar performance models. Additionally, the text discusses new applications including underwater acoustic networks and channel models, marine-hydrokinetic energy devices, and simulation of anthropogenic sound sources. It further includes instructive case studies to demonstrate applications in sonar simulation.
