In order to develop more efficient types of gears, further investigations into the theories of engagement is necessary. Up until now most of the research work on the theories of engagement has been carried out separately on different groups, and based on individual types of profiles. This book aims at developing some universal theories, which can not only be used for all types of gears, but can also be utilized in other fields such as sculptured surfaces. The book has four characteristics: the investigations are concentrated on mismatched tooth surfaces; all the problems are dealt with from a differential geometry point of view; most theories and algorithms are universal in application; and the algorithms are easy to follow and can be used in real situations. In the process of developing the algorithms, the authors have introduced some mathematical methods which are believed to be innovative with regard to the theories of engagement known so far. A theoretical treatment is presented throughout the book, supported by numerical examples and experiments. With the computer programmes listed at the end of the volume, any of the proposed methods can be easily utilized in practice. The book is intended for postgraduate students, lecturers, professors, or research staff in mechanical/manufacturing engineering, mathematics and R&D departments of research institutes and universities. It should also be useful for engineers working in the gear manufacturing sector of industry.

Distribution of Statistical Observables for Anomalous and Nonergodic Diffusions

This book investigates statistical observables for anomalous and nonergodic dynamics, focusing on the dynamical behaviors of particles modelled by non-Brownian stochastic processes in the complex real-world environment. Statistical observables are widely used for anomalous and nonergodic stochastic systems, thus serving as a key to uncover their dynamics. This study explores the cutting edge of anomalous and nonergodic diffusion from the perspectives of mathematics, computer science, statistical and biological physics, and chemistry. With this interdisciplinary approach, multiple physical applications and mathematical issues are discussed, including stochastic and deterministic modelling, analyses of (stochastic) partial differential equations (PDEs), scientific computations and stochastic analyses, etc. Through regularity analysis, numerical scheme design and numerical experiments, the book also derives the governing equations for the probability density function of statistical observables, linking stochastic processes with PDEs. The book will appeal to both researchers of electrical engineering expert in the niche area of statistical observables and stochastic systems and scientists in a broad range of fields interested in anomalous diffusion, especially applied mathematicians and statistical physicists.

Microwave photonic signal processing has attracted significant interest in diverse areas including communications, radars, sensors, instrumentations and so on. This is because it offers the prospect of realising extremely high multigigahertz sampling frequencies, overcoming inherent electronic bottlenecks for processing wide bandwidth signals. Besides that, it also has the supplementary advantages of tunability, reconfigurability and immunity to electromagnetic interference. This book presents two novel Sagnac loop based microwave photonic notch filters and two novel photonic microwave phase shifters. The performance of these processors is significantly improved compared with previous approaches, such as the resolution and the group delay of the notch filter, and the bandwidth and the complexity of the phase shifter. This book is intended for researchers and graduate students in the fields of photonics, optical engineering and microwave photonics.
