This book includes six chapters on wind turbine icing. For wind turbines operating in cold regions, icing often occurs on blade surfaces in winter. This ice accretion can change the aerodynamic shape of the blade airfoil, causing performance degradation and loss of power generation, even leading to operational accidents. This book focuses on the recent research progress on wind turbine icing. Chapters address such topics as the effect of icing conditions on the icing distribution characteristics of a blade airfoil for vertical-axis wind turbines, power loss estimation in wind turbines due to icing, wind turbine icing prediction methods, especially those using machine learning, the icing process of a single water droplet on a cold aluminum plate surface, the main theories of the icing adhesive mechanism, and theoretical and experimental studies on the ultrasonic de-icing method for wind turbine blades. This book is a valuable reference for researchers and engineers engaged in wind turbine icing and anti-icing research.

This book focuses on the multifaceted reality of social and health constraints and health services access among migrants in China, by originally exploring the social strata, social networks, and the understanding of health and health services among migrants. Furthermore, this book investigates the health constraints and health services access of rural-urban migrants in the absence of equal social protection by the government. It argues that the main obstacles to access health services are not only the shortage of financial resources among rural-urban migrants, but also lie in the institutional blindness regarding health security provision, rural-urban dualism and the household registration system in China. The book highlights the key function that social networks play in health and health services access among migrants in China, which has rarely been discussed in previous studies. And it also discusses the understanding of health among migrants, and further analyses that althoughmany migrants have not formed proper understanding of the connotation of health and have limited knowledge of health, prime responsibility should not be put on the migrants because their poor understanding of health mainly results from their rural perspective while health and health services access depend on the social-economic environment in which they live and work.This book would be of interest to people in migration studies, social exclusion and social welfare studies and to people interested in rural-urban migration and health in China.

This book comprehensively and systematically introduces the microstructure characteristics of plant fibers and the manufacturing process, interface characteristics, mechanical behaviors and physical properties of plant fiber reinforced composites, as well as their engineering demonstration applications. Plant fibers derived from natural resources have been thrust into the global spotlight as environment-friendly materials with attractive advantages of renewability, biodegradability, high specific strength and modulus and good sound absorption and heat insulation performance, and have become promising alternative to traditional synthetic fibers in making fiber-reinforced composites with structure-function integration. This book combines the basic theory with engineering applications for highlighting the unique research method for plant fiber reinforced composites with hierarchical structure. It is intended for undergraduate and graduate students who are interested in natural fiber composites, and scientific researchers and engineers looking to develop the design and manufacture of green composites in the fields of aerospace, railway transportation vehicles, automotive engineering and civil infrastructures.
