Written at an intermediate level in a way that is easy to understand, Fundamentals and Applications of Ultrasonic Waves, Second Edition provides an up-to-date exposition of ultrasonics and some of its main applications. Designed specifically for newcomers to the field, this fully updated second edition emphasizes underlying physical concepts over mathematics. The first half covers the fundamentals of ultrasonic waves for isotropic media. Starting with bulk liquid and solid media, discussion extends to surface and plate effects, at which point the author introduces new modes such as Rayleigh and Lamb waves. This focus on only isotropic media simplifies the usually complex mathematics involved, enabling a clearer understanding of the underlying physics to avoid the complicated tensorial description characteristic of crystalline media. The second part of the book addresses a broad spectrum of industrial and research applications, including quartz crystal resonators, surface acoustic wave devices, MEMS and microacoustics, and acoustic sensors. It also provides a broad discussion on the use of ultrasonics for non-destructive evaluation. The author concentrates on the developing area of microacoustics, including exciting new work on the use of probe microscopy techniques in nanotechnology. Focusing on the physics of acoustic waves, as well as their propagation, technology, and applications, this book addresses viscoelasticity, as well as new concepts in acoustic microscopy. It updates coverage of ultrasonics in nature and developments in sonoluminescence, and it also compares new technologies, including use of atomic force acoustic microscopy and lasers. Highlighting both direct and indirect applications for readers working in neighboring disciplines, the author presents particularly important sections on the use of microacoustics and acoustic nanoprobes in next-generation devices and instruments.

Ultrasonic Methods for Measurement of Small Motion and Deformation of Biological Tissues for Assessment of Viscoelasticity - Hideyuki Hasegawa - Bog -

Ultrasonic Methods for Measurement of Small Motion and Deformation of Biological Tissues for Assessment of Viscoelasticity - Hideyuki Hasegawa - Bog -

In this monograph, an accurate ultrasonic method for measurement ofsmall motion and deformation of biological tissue is described. In thedisplacement estimation based on the phase change of echoes, the displacementestimates are biased when the center frequency of the RF echochanges. Such an apparent change in the center frequency could be causedby the interference of echoes from scatterers. To reduce the influence ofthe center frequency variation on the estimation of motion and deformation,an error correcting function, which does not require the assumptionthat the center frequency distributions in 2 different frames are the same,was introduced. As a result, the proposed method provides better strainestimates in comparison with conventional phase-sensitive correlationmethods.This monograph also shows examples of applications of this method tomeasurement of small motion and deformation of biological tissues. Thismethod can be applied to measurement of elasticity of dynamic tissues,such as the artery. Also, elastic properties of static tissues can be also measuredby combining with actuation using the acoustic radiation force.

Physical Ultrasonics of Composites - Stanislav Rokhlin - Bog - Oxford University Press Inc - Plusbog.dk

Physical Ultrasonics of Composites - Stanislav Rokhlin - Bog - Oxford University Press Inc - Plusbog.dk

This book is a rigorous introduction to the characterization of composite materials by means of ultrasonic waves. Composites are treated here not simply as uniform media, but as inhomogeneous layered anisotropic media with internal structure characteristic of composite laminates. The objective here is to concentrate on exposing the singular behavior of ultrasonic waves as they interact with layered, anisotropic materials, materials which incorporate those structural elements typical of composite laminates. This book provides a synergistic description of both modeling and experimental methods in addressing wave propagation phenomena and composite property measurements. After a brief review of basic composite mechanics, a thorough treatment of ultrasonics in anisotropic media is presented, along with composite characterization methods. The interaction of ultrasonic waves at interfaces of anisotropic materials is discussed, as are guided waves in composite plates and rods. Waves in layered media are developed from the standpoint of the "Stiffness Matrix", a major advance over the conventional, potentially unstable Transfer Matrix approach. Laminated plates are treated both with the stiffness matrix and using Floquet analysis. The important influence on the received electronic signals in ultrasonic materials characterization from transducer geometry and placement are carefully exposed in a dedicated chapter. Ultrasonic wave interactions are especially susceptible to such influences because ultrasonic transducers are seldom more than a dozen or so wavelengths in diameter. The book ends with a chapter devoted to the emerging field of air-coupled ultrasonics. This new technology has come of age with the development of purpose-built transducers and electronics and is finding ever wider applications, particularly in the characterization of composite laminates.

Empires of Light - Niharika Dinkar - Bog - Manchester University Press - Plusbog.dk

Empires of Light - Niharika Dinkar - Bog - Manchester University Press - Plusbog.dk

In his Reflections on the Revolution in France , Edmund Burke discerned a ‘new conquering empire of light and vision’ that he associated with the rhetoric of Enlightenment thought. This book expands on Burke’s protean metaphor, examining the role of light in imperial optics through a study of nineteenth-century Indian visual practices. Light was central to the visual politics and imaginative geographies of empire, beyond its simplistic valorisation as a symbol of knowledge and progress in post-Enlightenment narratives. Geographical spaces were mapped in terms of ‘cities of light’ and ‘hearts of darkness’, and ‘the civilising mission’ frequently employed iconographies of torches or the lifting of the veil to indicate a passage into rationality. Empires of light describes how an imperial regime deployed light and visibility as technologies of colonial control. Taking in the industrialisation of light (in homes, streets, theatres) and its instrumentalisation through an industry of representation (photography, film, magic lanterns, theatrical lighting), the book examines the works of celebrated painter Ravi Varma (1848–1906) and the colonial subjects – from elite artists to subalterns – produced by the encounter with imperial technologies of vision.Theoretically sophisticated and richly illustrated with many previously unpublished images, Empires of light makes a substantial contribution to our understanding of visual culture in colonial India. It is essential reading for students and scholars of South Asian art history, film and media studies.
