Book Description
In the oil and gas industries, large companies are endeavoring to find and utilize efficient structural health monitoring methods in order to reduce maintenance costs and time. Through an examination of the vibration-based techniques, this title addresses theoretical, computational and experimental methods used within this trend.By providing comprehensive and up-to-date coverage of established and emerging processes, this book enables the reader to draw their own conclusions about the field of vibration-controlled damage detection in comparison with other available techniques. The chapters offer a balance between laboratory and practical applications, in addition to detailed case studies, strengths and weakness are drawn from a broad spectrum of information.

Book Description
This paper describes the application of two different computer based optical methods for locating the positions ans amplitudes of nodes and antinodes in vibrating members. In a technique called shadow speckle metrology, artificial speckles are projected at an angle onto a vibrating surface using a 35mm projector and a speckled slide. In the second technique called line broadening, a single line is used for projection. The vibrating surface and the projected images are captured either directly using a vidicon camera/digitizer system, or indirectly using an ordinary camera to record a time average photograph which is digitized subsequently. Computer programs compare these images to images recorded prior to excitation in order to determine the mode shape and the amplitude of vibration. Keywords: Vibration Analysis, Modal Analysis, Speckle Metrology; Reprints.

Book Description
Speckle Metrology presents a diverse and wide collection of metrological speckle techniques and applications. The book discusses both theoretical concepts and experimental methods in speckle-based measurements. Some chapters introduce speckle terminology and the physical characteristics of speckle. Other aspects also covered in the book include methodology, system geometries, data reduction procedures, and specific applications. These applications are discussed in detail in individual chapters, such as structures inspection. Adaptation of speckle measurement techniques in video recording and processing technology is also given emphasis in one chapter. Finally, one chapter is dedicated to a discussion on the speckle interferometer as one of the most used instrument in metrological speckle application. This text is a valuable reference to students in the fields of engineering and applied science.

Book Description
Modern Practice in Stress and Vibration Analysis documents the proceedings of the conference on Modern Practice in Stress and Vibration Analysis organized by the Stress Analysis Group of the Institute of Physics at the University of Liverpool, 3-5 April 1989. The Group has been known in the UK for its contribution in providing meetings with an emphasis on application, covering topics which range widely to include modern numerical techniques and advanced experimentation. The volume contains 34 papers presented by researchers at the conference covering a wide range of topics such as the application of the sensitivity analysis method to structural dynamics; passive and active vibration control for use in vibration suppression in spacecraft; analysis of an ultrasonically excited thick cylinder; and the prediction of vibrational power transmission through a system of jointed beams carrying longitudinal and flexural waves. It is hoped that the contributions published in this book will be of value to the broad community of practitioners in stress and vibration analysis whom the Stress Analysis Group exists to serve.

Book Description
Speckle study constitutes a multidisciplinary area with inherent complexities. In order to conquer challenges such as the variability of samples and sensitive measurements, researchers must develop a theoretical and statistical understanding of both biological and non-biological metrology using dynamic speckle laser. Dynamic Laser Speckle and Applications discusses the main methodologies used to analyze biospeckle phenomena with a strong focus on experimentation. After establishing a theoretical background in both speckle and biospeckle, the book presents the main methodologies for statistical and image analysis. It then deals with the concept of frequency decomposition before moving on to a discussion of fuzzy methods to treat dynamic speckle data. The book dedicates two sections to applications, including agricultural approaches. Additional features include photo images of experiments and software to aid in easy start-up of dynamic speckle usage. A systematic approach to new dynamic speckle laser phenomena, this book provides the physical theory and statistical background needed to analyze images formed by laser illumination in biological and non-biological samples.
