'This booklet provides a very lucid and versatile introduction to the methods of linear partial differential equations. It covers a wealth of very important material in a concise, nevertheless very instructive manner, and as such it may serve as an excellent guide to further, more advanced and detailed reading in this area of both classical and contemporary mathematics.'zbMATHPartial differential equations arise in many branches of science and they vary in many ways. No one method can be used to solve all of them, and only a small percentage have been solved. This book examines the general linear partial differential equation of arbitrary order m. Even this involves more methods than are known. We ask a simple question: when can an equation be solved and how many solutions does it have?The answer is surprising even for equations with constant coefficients. We begin with these equations, first finding conditions which allow one to solve and obtain a finite number of solutions. It is then shown how to obtain those solutions by analyzing the structure of the equation very carefully. A substantial part of the book is devoted to this. Then we tackle the more difficult problem of considering equations with variable coefficients. A large number of such equations are solved by comparing them to equations with constant coefficients.In numerous applications in the sciences, students and researchers are required to solve such equations in order to get the answers that they need. In many cases, the basic scientific theory requires the resulting partial differential equation to have a solution, and one is required to know how many solutions exist. This book deals with such situations.

Solid Acoustic Waves and Vibration: Theory and Applications is an exciting new book that takes readers inside a fascinating subject. It is charming that there is a complex and delicate structure in characteristic values, which is revealed by introducing a conceptual system including space operator, space-time variable, reference Poisson's ratio, etc., and developing the analytical models for all limiting cases. The dispersion curves of waves in an elastic plate are determined completely, and a systematic and concise description of the fundamental theory of this subject is given. As MEMS and NEMS technology develops, a number of new issues presents, such as the effects of residual stress, thin-film, air captured in micro-air-gaps and coating on the system, which make the problem complicated and spark debates. Micro-diaphragms are modeled by a plate in tension and mounted on air-spring, a general TDK equation of vibration of plates, including free, forced and damped vibrations, and its solutions are developed. The loading effect of coating is modeled by a mass load; a micro-load theory is presented. This book is a summary of the author's long-term research on electromechanical transducers and these related issues, and they provide an excellent description combining theory and application. The principle of electromechanical transducers, which achieve the conversion between mechanical and electrical energy, occupying a particularly important position in the field of robotics and intelligent machines, is elucidated by introducing the concepts of space-time operator, complex transformation factor, inversion impedance, etc., and an unfiled equivalent circuit is presented. The applications in micromachined capacitive ultrasonic transducers (mCUTs, CMUTs) for biomedical imaging and ultrasonic mass resonators (mUMRs) for biochemical sensing, including plate-type, beam-type, nanowire, bulk-wave, LAW and SAW delay-line ultrasonic resonators are described. This interdisciplinary book will be increasingly attractive as MEMS and NEMS technology develops.
