Sonic and Photonic Crystals


Book Description

Sonic/phononic crystals termed acoustic/sonic band gap media are elastic analogues of photonic crystals and have also recently received renewed attention in many acoustic applications. Photonic crystals have a periodic dielectric modulation with a spatial scale on the order of the optical wavelength. The design and optimization of photonic crystals can be utilized in many applications by combining factors related to the combinations of intermixing materials, lattice symmetry, lattice constant, filling factor, shape of the scattering object, and thickness of a structural layer. Through the publications and discussions of the research on sonic/phononic crystals, researchers can obtain effective and valuable results and improve their future development in related fields. Devices based on these crystals can be utilized in mechanical and physical applications and can also be designed for novel applications as based on the investigations in this Special Issue.




Electronic Circuits


Book Description

Electronic Circuits covers all important aspects and applications of modern analog and digital circuit design. The basics, such as analog and digital circuits, on operational amplifiers, combinatorial and sequential logic and memories, are treated in Part I, while Part II deals with applications. Each chapter offers solutions that enable the reader to understand ready-made circuits or to proceed quickly from an idea to a working circuit, and always illustrated by an example. Analog applications cover such topics as analog computing circuits. The digital sections deal with AD and DA conversion, digital computing circuits, microprocessors and digital filters. This editions contains the basic electronics for mobile communications. The accompanying CD-ROM contains PSPICE software, an analog-circuit-simulation package, plus simulation examples and model libraries related to the book topics.

Degrees of Reiki


Book Description

Degrees of reiki is guide to the use and practice of Reiki. It offers a variety of ways of using Reiki that will encourage the reader to use their own intuition when applying reiki to their particular needs. It is not a complete work as Reiki is beyond being confined to one way or practice and is far greater than what can be understood and encompassed by one person. However it is hoped that this book will extend the reader`s knowledge and use of reiki and open their minds to the vast possibilities that Reiki offers.

Electronic Servicing and Repairs


Book Description

This new title is based upon Trevor Linsley's successful Electronics for Electricians and Service Engineers and completely updates the previous text by taking into account the recent changes in the City and Guilds courses including 2240, 2360 and 2351. The new edition also incorporates hardware topics from the popular course, C&G 7261 Information Technology making this an indispensable reference for all those taking C&G courses. Trevor Linsley appproaches the subject in a practical, non-mathematical way, enabling both trainee and practising electricains and service engineers to relate electronics to their own experience. 'Electronic Servicing and Repairs' includes an expanded chapter on testing and fault diagnosis, incorporates PLCs and CAD software and introduces automatic text equipment (ATE). Communication and security systems are completely updated - the section on TV receivers, satellite TV, VCRs, CD players and cable TV has been expanded and a new chapter has been devoted to alarm systems.




Understanding and Servicing CD Players


Book Description

Written specifically with service technicians and engineers in mind, this book is designed as a bench-side companion and guide to the principles involved in repairing and adjusting CD players. Engineers will find this a helpful companion to the various service manuals. The text takes a problem solving approach with numerous examples, circuit diagrams and line drawings. Engineers who need to achieve a better understanding of CD technology will find this book an essential tool for fault diagnosis, adjustment and repair. This book not only covers the mechanical design but also the integrated circuits within a CD player. It is written for immediate application and is well illustrated, so it should become a welcome addition to the rack of tools available to the service engineer. Ken Clements has extensive experience of the service industry both as a service manager and later in technical training with Sony and Pioneer.
