Metaheuristics for Resource Deployment under Uncertainty in Complex Systems analyzes how to set locations for the deployment of resources to incur the best performance at the lowest cost. Resources can be static nodes and moving nodes while services for a specific area or for customers can be provided. Theories of modeling and solution techniques are used with uncertainty taken into account and real-world applications used.The authors present modeling and metaheuristics for solving resource deployment problems under uncertainty while the models deployed are related to stochastic programming, robust optimization, fuzzy programming, risk management, and single/multi-objective optimization. The resources are heterogeneous and can be sensors and actuators providing different tasks. Both separate and cooperative coverage of the resources are analyzed. Previous research has generally dealt with one type of resource and considers static and deterministic problems, so the book breaks new ground in its analysis of cooperative coverage with heterogeneous resources and the uncertain and dynamic properties of these resources using metaheuristics.This book will help researchers, professionals, academics, and graduate students in related areas to better understand the theory and application of resource deployment problems and theories of uncertainty, including problem formulations, assumptions, and solution methods.

The book examines concurrent green initiatives and their spillover effects on environmental conservation and management to reveal their impact on conservation effectiveness, drawing on a range of international case studies. Green initiatives are programs, payments, or endeavors that restore, sustain, or improve nature’s capacity, with examples including payments for ecosystem services and the development of nature reserves and protected areas. This book explicitly examines concurrent green initiatives, where initiatives overlap either geographically or in terms of recipients of multiple payments. The book provides a detailed analysis of case studies in the USA and China, including the USA-based Conservation Reserve Program and the Environmental Quality Incentives Program, and the China based Grain-to-Green Program and the Forest Ecological Benefit Compensation Fund. Through this comparison, the book shows the impact of concurrent green initiatives, including additional or unintended benefits for conservation and local communities as well as negative spillover effects. The book complements these case studies by drawing on other global examples ranging in size from local to continental, including planting native trees and shrubs in Australia and green initiatives in the Baltic Sea region. Overall, this book demonstrates the importance of analyzing concurrent green efforts to better understand both the positive and negative impacts to ensure the optimal effectiveness of these policies and programs for conservation and environmental management. This book will be of great interest to students and scholars of environmental conservation and management, land use, ecosystem services and environmental policy, as well as policymakers and practitioners working on environmental initiatives and programs.

Why do political elites in authoritarian regimes, even within the same country, engage in different levels of predatory behavior, whereby some foster vibrant capitalism and others suffocate the innovative private sector? This book proposes a theory of localized property-rights protection under authoritarianism. By combining in-depth fieldwork with archival research and quantitative data analysis, Qi Zhang and Mingxing Liu discuss the post-1949 conflicts between dominant and marginalized factions in the Chinese province of Zhejiang. These conflicts resulted in systemic vulnerabilities among the marginalized local cadres, thus motivating them to form alliances with their grassroots constituents. They therefore provided their constituents with quasi-public goods, such as property-rights protection, to increase their odds of political survival. Zhang and Liu argue that this framework can apply both to the Mao era and to the current reform era, and it also can be extended beyond China to a wider context.

Since the 1997 Kyoto protocol of reduction of greenhouse gas emissions, the development of novel refrigerators has been a priority within the scientific community. Although magnetocaloric materials are promising candidates, they still need a large magnetic field to induce a giant ΔT as well as powerful and costly magnets. However, in electrocaloric materials (ECMs) a temperature change may be achieved by applying or removing an electric field. Since a giant electrocaloric effect on ferroelectric thin films was reported in Science in 2006, researchers have been inspired to explore such effect in different ferroelectric thin films. This book reviews electrocaloric effects observed in bulk materials as well as recent promising advances in thin films, with special emphasis on the ferroelectric, antiferroelectric and relaxor nature of ECMs. It reports a number of considerations about the future of ECMs as a means of achieving an efficient, ecologically sustainable and low cost refrigerator.

This book is designed primarily to meet two objectives. It is intended to serve as a textbook for a one-semester university course for graduate or senior undergraduate students in the physical sciences, electrical engineering and other related disciplines, or it may be used as a reference book for those who are working in the field. For those intending to use the book for self-study, a general knowledge of electromagnetism, electrical circuitry and plasma and discharge physics is necessary. In order to meet these diverse objectives, the authors have attempted to make the book reasonably compact so that it can fit in a one-semester schedule while retaining its comprehensiveness in serving as a reference book. The contents are arranged so that theory and practice are proportionally balanced and each topic consists of essentially four basic elements: fundamental principles, mathematical expressions and formulas, examples and illustrations, numerical data and applications. In order to keep its compactness, lengthy theoretical discussions and detailed mathematical derivations are avoided whenever possible.
