Book Description
The purpose of the School, the content of which is reflected in this book, is to bring together experiences and knowledge of those acousticians who are particularly sensible to materials and their properties, specifically to those materials that may be called inhomo geneous. The two things together: acoustics and inhomogeneity, define factually a dimension less parameter, AI a, which is the ratio between the sound wavelength and the spatial length of the material where its physical characteristics notably change. An implicit defmition is, therefore, at hand for an inhomogeneous medium, which has the characteristic of a condi tioned definition and sets a looser constraint to the otherwise strict statement of invariance under translations. Composite, biologicai, porous, stratified materials are in the list of inhomogeneous materials, whose technological or structural interest has grown greatly in recent times. Ul trasonic waves offer a means for their investigation, which is valuable for it can be non destructive, continuous in time, spatially localized, dependent on the size of inhomoge neities.

Book Description
This book on the Nondestructive Characterization and Imaging of Wood by Professor Voichita Bucur is truly the most outstanding reference on the subject ever written. Since the origins of mankind, wood has played a key role in the history of humans and other living creatures, ranging from provision of life from trees giving air, heat, light, and food to nourish their bodies to structures to protect them from the elements. Wood has also played a key role in one of the world's primary religions. Nondestructive diagnostics methods have long found application in medi cal practice for examination of the human body in order to detect life threatening abnormalities and permit diagnosis to extend life. Nondestructive testing has been used for many years to insure the safety of machinery, air craft, railroads, tunnels, buildings and many other structures. Therefore, it is timely for a treatise, like the present one, to be written describing how wood can be characterized without employing destructive test methods. Since wood is so valuable to mankind, it is important to know the latest methods to nondestructively characterize wood for all practical applications.

Book Description
Acoustics of Wood offers a detailed treatment of numerous topics that are valuable to those working with wood in architecture, engineering, acoustics, and the crafting of musical instruments. It presents a comprehensive account of the progress and current knowledge concerning wood acoustics, outlining the anatomy and physiology of wood and the specific applications in which its acoustic properties are relevant. Acoustics of Wood reviews state-of-the-art measurement systems and includes material that has not been widely published. Divided into three main parts, the book describes environmental acoustics, presents acoustics methods for the characterization of the elastic behavior of wood, and discusses acoustic methods for the assessment of wood quality.

Book Description
Considerable activity in the acoustics of wood has occurred since the first edition of this book in 1995. An informal survey of a number of the published articles and papers presented at international conferences revealed that the interest of the wood science community is continually increasing. In this context, I felt c- pelled to revise the text in accordance with newer findings and this prompted the addition in the present book of 159 new references added to the existing 850 in the first edition. As a result of the favorable comments upon the first edition, from students and colleagues, I have included a part on mathematical theory related to wave pro- gation in orthotropic solids in the general text, in order to enable the interested reader to follow the essentially physical aspects of the subject. A new chapter related to “acousto-ultrasonics” is introduced; Chapters 4, 5, 6, 8, 9, 10, 11, and 12 have been considerably expanded and a significant redistribution of the subject matter from the earlier edition has been made.

Book Description
Conventional ultrasonic methods based on ultrasonic characteristics in the linear elastic region are mainly sensitive to mature defects but are much less responsive to micro-damage or incipient material degradation. Recently, nonlinear ultrasonic characteristics beyond the linear ultrasonic amplitude range have been studied as a method for overcoming this limitation, and hence, many researchers are engaged in theoretical, experimental, and various application studies. However, the nonlinear ultrasonic characteristics are quite exacting compared to the linear phenomena so that they require vast experience and high proficiency in order to obtain proper experimental data. Actually, many researchers, especially beginners including graduate students, have difficulty in reliably measuring nonlinear ultrasonic characteristics. This book provides key technological know-how from experts with years of experience in this field, which will help researchers and engineers to obtain a clear understanding and high quality data in the nonlinear ultrasonic experiments and applications.
