This book describes the development of the power matching problem. It starts with the derivative-free proof of conjugate matching, goes through the nonlinear, resistive maximum power theorem and its reversal, extension of the concept of equivalence in the case of nonlinear circuits, application of the nonlinear, and resistive maximum power theorem for diode measurement. The author treats practically important special cases of nonlinear, dynamic power matching with applications, and the most general solution that is not realizable. Discusses the derivative-free proof of conjugate matching, the problem of equivalence in nonlinear circuits; Covers applications of the theory presented, such as maximum power load of a microwave power amplifier, image parameter matching, and application of power matching for economical problems; Includes proof of existence of the scattering matrix and causality of linear, passive circuits; Includes a table containing all known formulae for power matching.

Soft Power written by Hendrik W. Ohnesorge and has been published by Springer Nature this book supported file pdf, txt, epub, kindle and other format this book has been release on 2019-11-22 with Political Science categories.
This book explores the phenomenon of soft power in international relations. In the context of current discourses on power and global power shift s, it puts forward a comprehensive taxonomy of soft power and outlines a methodological roadmap for its empirical study. To that end, the book classifies soft power into distinct components - resources, instruments, reception, and outcomes - and identifies relevant indicators for each of these categories. Moreover, the book integrates previously neglected aspects into the concept of soft power, including the significance of (political) personalities. A broad range of historical examples is drawn upon to illustrate the effects of soft power in international relations in an innovative and analytically differentiated way. A central methodological contribution of this book consists in highlighting the value of comparative-historical analysis (CHA) as a promising approach for empirical analyses of the soft power of different actors on the international stage. By introducing a comprehensive taxonomy of soft power, the book offers an innovative and substantiated perspective on a pivotal phenomenon in today’s international relations. As the forces of attraction in world politics continue to gain in importance, it provides a valuable asset for a broad readership. This book was the winner of the 2021 ifa (German Institute for Foreign Cultural Relations) Research Award on Foreign Cultural Policy. “In this important and thoughtful book, Hendrik Ohnesorge explains and advances our knowledge of the ways that soft power, public diplomacy, and charismatic personal diplomacy are shaping the international relations of our global information age.” Joseph S. Nye, Jr., Harvard University and author of The Future of Power
