EMATs for Science and Industry

Noncontacting Ultrasonic Measurements

By: Masahiko Hirao,Hirotsugu Ogi

EMATs for Science and Industry comprises the physical principles of electromagnetic acoustic transducers (EMATs) and the applications to scientific and industrial ultrasonic measurements on materials. The text is arranged in four parts: -PART I is intended to be a self-contained description of the basic elements of coupling mechanism along with practical designing of EMATs for various purposes. There are several implementations to compensate for the low transfer efficiency of the EMATs. Useful tips to make an EMAT are also presented. -PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of contactless nature of EMATs and is the most successful amplification mechanism for precise velocity and attenuation measurements. -PART III applies EMAR to studying the physical acoustics. New measurements emerged on three major subjects; in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, and acoustic nonlinearity evolution. -PART IV deals with a variety of individual topics encountered in industrial applications, for which the EMATs are believed to the best solutions.

Electromagnetic Acoustic Transducers

Noncontacting Ultrasonic Measurements using EMATs

By: Masahiko Hirao,Hirotsugu Ogi

This second edition provides comprehensive information on electromagnetic acoustic transducers (EMATs), from the theory and physical principles of EMATs to the construction of systems and their applications to scientific and industrial ultrasonic measurements on materials. The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts: PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs’ low transfer efficiency are provided, along with useful tips on how to make an EMAT. PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs’ contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation. PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution. PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications.

Transboundary Game of Life

Memoir of Masahiko Aoki

By: Masahiko Aoki

The central part of this book is an English version of the memoir of Masahiko Aoki that was published in Japanese in 2008 (青木昌彦『私の履歴書人生越境ゲーム』日本経済新聞出版社). In this memoir, Aoki goes over his life as a young boy immediately after World War II, as an activist who opposed the rearmament of Japan under the US-Japan Security Alliance, as a student of Marxist economics first and then modern mathematical economics, as a graduate student at Minnesota, as a young economist at Stanford, Harvard, and then Kyoto, as a central faculty member to develop comparative institutional analysis at Stanford, and as an institutional builder who established the Stanford Kyoto Center, the Research Institute of Economy, Trade, and Industry, the Virtual Center for Advanced Studies Institution in Tokyo, and the Center for Industrial Development and Environmental Governance in Beijing. Until now the memoir has been available only in Japanese and in Chinese. The English edition will allow more young social scientists to touch the life and the work of Masahiko Aoki and be inspired to make their own versions of the “transboundary game of life.”
