Автор: M. Kato

Год издания: 

This book will serve as an ideal guide to the relatively new and complex field of bioelectromagnetics for students and researchers interested in the interaction of biological systems and electromagnetic fields. Coverage details:(1) biological responses of human and animals, both in vivo and in vitro methodologies, to magnetic and/or electromagnetic field exposure, (2) characteristics of effective fields, (3) hypotheses to explain possible mechanisms of interaction between the fields and cells, and (4) induced current in ELF and induced heat in RF fields as key interaction mechanisms.

Bringing Strategy Back. How Strategic Shock Absorbers Make Planning Relevant in a World of Constant Change Bringing Strategy Back. How Strategic Shock Absorbers Make Planning Relevant in a World of Constant Change

Автор: Jeffrey Sampler L.

Год издания: 

Reconsider Strategy and Make Planning Relevant In Bringing Strategy Back, strategy expert Jeffrey Sampler cuts through the clutter to reveal exactly why the usual tools of strategy are so sorely out of sync with our needs: windows of opportunity close far faster than they once did, many of these opportunities are smaller than they once were, growth rates are uneven across markets, and today's competition is more asymmetrical than ever. The upshot for managers is that they need to reorient their approach to absorb the shocks and surprises that strike at a moment's notice. Only then can strategic planning reliably play its part. Leaders all around the world at organizations of any size and type will benefit by shedding their obsolete notions about strategy and becoming more resilient. Bringing Strategy Back rises to the challenge and presents a new prescriptive model. It introduces four «strategic shock absorbers» that enable leaders to build resilient organizations that can withstand even the most unexpected global turbulence. Based on the author's in-depth research in the world's most tempestuous markets, the model delivers several must-have qualities that interact and work together in an ongoing process: Accuracy, Agility, Momentum, and Foresight. With this new framework, Bringing Strategy Back shows how to be prepared and proactive, rather than reactive, even when the future is uncertain.

Field Computation for Accelerator Magnets. Analytical and Numerical Methods for Electromagnetic Design and Optimization Field Computation for Accelerator Magnets. Analytical and Numerical Methods for Electromagnetic Design and Optimization

Автор: Stephan Russenschuck

Год издания: 

Written by a leading expert on the electromagnetic design and engineering of superconducting accelerator magnets, this book offers the most comprehensive treatment of the subject to date. In concise and easy-to-read style, the author lays out both the mathematical basis for analytical and numerical field computation and their application to magnet design and manufacture. Of special interest is the presentation of a software-based design process that has been applied to the entire production cycle of accelerator magnets from the concept phase to field optimization, production follow-up, and hardware commissioning. Included topics: Technological challenges for the Large Hadron Collider at CERN Algebraic structures and vector fields Classical vector analysis Foundations of analytical field computation Fields and Potentials of line currents Harmonic fields The conceptual design of iron- and coil-dominated magnets Solenoids Complex analysis methods for magnet design Elementary beam optics and magnet polarities Numerical field calculation using finite- and boundary-elements Mesh generation Time transient effects in superconducting magnets, including superconductor magnetization and cable eddy-currents Quench simulation and magnet protection Mathematical optimization techniques using genetic and deterministic algorithms Practical experience from the electromagnetic design of the LHC magnets illustrates the analytical and numerical concepts, emphasizing the relevance of the presented methods to a great many applications in electrical engineering. The result is an indispensable guide for high-energy physicists, electrical engineers, materials scientists, applied mathematicians, and systems engineers.

Numerical Analysis in Electromagnetics. The TLM Method Numerical Analysis in Electromagnetics. The TLM Method

Автор: Pierre Saguet

Год издания: 

The aim of this book is to give a broad overview of the TLM (Transmission Line Matrix) method, which is one of the “time-domain numerical methods”. These methods are reputed for their significant reliance on computer resources. However, they have the advantage of being highly general. The TLM method has acquired a reputation for being a powerful and effective tool by numerous teams and still benefits today from significant theoretical developments. In particular, in recent years, its ability to simulate various situations with excellent precision, including complex materials, has been demonstrated. Application examples are included in the last two chapters of the book, enabling the reader to draw conclusions regarding the performance of the implemented techniques and, at the same time, to validate them. Contents 1. Basis of the TLM Method: the 2D TLM Method. 2. 3D Nodes. 3. Introduction of Discrete Elements and Thin Wires in the TLM Method. 4. The TLM Method in Matrix Form and the Z Transform. Appendix A. Development of Maxwell’s Equations using the Z Transform with a Variable Mesh. Appendix B. Treatment of Plasma using the Z Transform for the TLM Method.
