Available in PDF, EPUB and Kindle. Book excerpt: SAW devices are widely used in multitude of device concepts mainly in MEMS and communication electronics. As such, SAW based micro sensors, actuators and communication electronic devices are well known applications of SAW technology. For example, SAW based passive micro sensors are capable of measuring physical properties such as temperature, pressure, variation in chemical properties, and SAW based communication devices perform a range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, and convolvers. In recent decades, SAW based low-powered actuators and microfluidic devices have significantly added a new dimension to SAW technology. This book consists of 20 exciting chapters composed by researchers and engineers active in the field of SAW technology, biomedical and other related engineering disciplines. The topics range from basic SAW theory, materials and phenomena to advanced applications such as sensors actuators, and communication systems. As such, in addition to theoretical analysis and numerical modelling such as Finite Element Modelling (FEM) and Finite Difference Methods (FDM) of SAW devices, SAW based actuators and micro motors, and SAW based micro sensors are some of the exciting applications presented in this book. This collection of up-to-date information and research outcomes on SAW technology will be of great interest, not only to all those working in SAW based technology, but also to many more who stand to benefit from an insight into the rich opportunities that this technology has to offer, especially to develop advanced, low-powered biomedical implants and passive communication devices.

Download or read book Sound of Stones written by Fang Xueyang and published by Ekho Verlag. This book was released on 2022-12-31 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on researching the chime stone, a percussion instrument carved from stone that originated in ancient China. In antiquity, people regarded the chime stone as an important musical instrument because its presence indicated the wealth and status of the tomb owners. In the late Neolithic Age, people discovered the differences between each type of stone and their sound qualities. Chime stone manufacture focused on the timbre of the natural stone, as opposed to both materials and sounding based selection in later periods, which formed a part of making a perfect and delicate chime stone. In the earlier period the chime stone was only a musical instrument for producing rhythmic sound, but as time went by, chime stones gradually became melodic instruments and were played with string, wind, and other percussion instruments in ensemble. The book is divided into 10 chapters. Chapter 1 provides a comprehensive view of existing research, sets out the aims of the present research alongside material sources and methodology, elaborates the theoretical framework of the book, and clarifies terminology in both English and Chinese. A summary of the main chime stone finds of the Yellow River andthe Yangtze River valley areas, together with geographical features of these distributions, is provided in Chapter 2. Chapters 3 to 8 contain an in-depth discussion of the chime stones unearthed from those regions, including classification and typology, shape, manufacture, assemblage and performance of the chime stones as well as the detailed tone measurementand analysis. Chapter 9 examines the acoustic properties of chime stones. Chapter 10 looks at the use and function of chime stones, which includes the role of chime stones in ancient ensembles, cultural context, use in ritual music, and the symbolic meaning of chime stones in ancient China.

Available in PDF, EPUB and Kindle. Book excerpt: IMAGE TRACKS AT HALIFAX by L.B. Felsen All living kind much effort spend Some model modes, some model rays, To cope with their environment Some feel that spectra all portrays. Some use their eyes, some use their nose Then there are those who with despatch, To sense where other things repose. Take refuge in the ocean wedge. For one group, nothing's more profound Than to explore the world with sound. If things get messy, randomize. These audio diagnosticians What's partly smooth, determinize. You ponder, is it this or that? Go by the name of acousticians. And wish you were a lowly bat They regularly meet to check Whether their sonogram's on track. The meeting's hosts did treat us well. With images stored in their packs, They let the climate cast its spell. This year they came to Halifax. No weath'ry hope was placed in vain. There they combined with ocean types We were exposed to wind and rain, And each could hear the other's gripes. We glimpsed blue sky through clouds dispersed. A meeting naturally does start But rainy sequence was reversed: Reviewing present state of art. The ocean types would like it wet What we found out is where it's at: Yet they got stuck with sun instead. We cannot hope to match the bat Each confrence has the same refrain: Computer printouts by the reams It has been fun to meet again.

Download or read book Noise of Polyphase Electric Motors written by Jacek F. Gieras and published by CRC Press. This book was released on 2018-10-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling the level of noise in electrical motors is critical to overall system performance. However, predicting noise of an electrical motor is more difficult and less accurate than for other characteristics such as torque-speed. Recent advances have produced powerful computational methods for noise prediction, and Noise of Polyphase Electric Motors is the first book to collect these advances in a single source. It is also the first to include noise prediction for permanent magnet (PM) synchronous motors. Complete coverage of all aspects of electromagnetic, structural, and vibro-acoustic noise makes this a uniquely comprehensive reference. The authors begin with the basic principles of noise generation and radiation, magnetic field and radial forces, torque pulsations, acoustic calculations, as well as noise and vibration of mechanical and acoustic origin. Moving to applications, the book examines in detail stator system vibration analysis including the use of finite element method (FEM) modal analysis; FEM for radial pressure and structural modeling; boundary element methods (BEM) for acoustic radiation; statistical energy analysis (SEA); instrumentation including technologies, procedures, and standards; and both passive and active methods for control of noise and vibration. Noise of Polyphase Electric Motors gathers the fundamental concepts along with all of the analytical, numerical, and statistical methods into a unified reference. It supplies all of the tools necessary to improve the noise performance of electrical motors at the design stage.
Download or read book Suspended Music written by Lothar von Falkenhausen and published by Univ of California Press. This book was released on 1994-03-16 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chinese made the world's first bronze chime-bells, which they used to perform ritual music, particularly during the Shang and Zhou dynasties (ca. 1700-221 B.C.). Lothar von Falkenhausen's rich and detailed study reconstructs how the music of these bells—the only Bronze Age instruments that can still be played—may have sounded and how it was conceptualized in theoretical terms. His analysis and discussion of the ritual, political, and technical aspects of this music provide a unique window into ancient Chinese culture. This is the first interdisciplinary perspective on recent archaeological finds that have transformed our understanding of ancient Chinese music. Of great significance to the understanding of Chinese culture in its crucial formative stage, it provides a fresh point of departure for exploring later Asian musical history and offers great possibilities for comparisons with music worldwide.
