Featuring easy-to-understand explanations of theory and underlying mathematics principles, this book provides readers with a complete introduction to fluid power, including hydraulics and pneumatics. The differences and similarities between hydraulics and pneumatics are identified, allowing readers to leverage their knowledge en route to new skills. Detailed color illustrations, photographs, and color-enhanced schematics are used effectively to add clarity to discussion of the construction and function of components. A dedicated section on component specifications is featured in each chapter, while realistic numbers are used and problems are stated in such a way as to develop practical system design skills. Knowledge of college-level algebra is assumed, but no trigonometry or calculus is required, making this book ideal for the technologist. Nomenclature, metric prefixes and conversion factors, equations, and graphic symbols are located in handy appendices for use by readers as they progress through the book. An introduction to the industry, plus a comprehensive glossary, is also included for the benefit of those who are just beginning their study of fluid power. Benefits: * Color is used in technical illustrations throughout the book, improving the readers' ability to distinguish between the parts that make up a component. * Schematics feature flow paths traced in color, so that readers can learn to read schematics while gaining an understanding of basic circuit operations. * Equations and examples for US Customary and SI (Metric) units are given separately, providing the flexibility to cover both systems or place more emphasis on one vs. the other. * Component specifications sections are featured in each chapter, offering insight into how components are evaluated and selected from manufacturers' catalogs. * Chapters on components are designed to stand-alone and may be covered in any order, so that they correspond to laboratory ex

This book constitutes a multidisciplinary introduction to the analysis of air defence systems. It supplies the tools to carry out independent analysis. Individual sections deal with threat missions, observability, manoeuvrability and vulnerability. With the support of several examples, the text illustrates 12 air defence process models. These models form the foundation for any air defence system analysis, covering initial detection to kill assessment.

This book offers a timely and compelling explanation for the deterioration of U.S.-China security relations during the Obama Presidency. The U.S.-China relationship has become one of (if not the most) vital features of contemporary world politics, and with arrival the Donald Trump to the White House in 2017, this vital geopolitical relationship sits at a precarious and dangerous crossroads. This book assesses a wide array of sources to systematically unpack the policy rhythms, drivers, and dynamics that defined the course of Sino-American security relations during the Obama-era. It fills several gaps in the literature on international security and conflict and offers a nuanced and innovative comparative approach to examine individual military domains. The case study chapters draw on recent Chinese and English sources - on military doctrine, capabilities, and defense strategy - to build a clear understanding the main sources of U.S.-China misperceptions, and highlight the problems these assessments can create for the conduct of statecraft across strategically competitive geopolitical dyads. The book builds a sobering picture of U.S.-China relations that will appeal to specialists and generalists alike with an interest in future warfare, emerging military-technologies, military studies, arms control, and foreign policy issues in the Asia-Pacific region more broadly.

Discover the universal language of childhood!

"Play, Development, and Early Education" challenges the reader to discover what play is and how to incorporate it into a curriculum for children from toddlerhood through the primary grades. The nature of play as a mode for learning is examined through three core ideas: the quality of play in early childhood, play as a means of self-expression, and play as a channel of communication to achieving social sense. In addition, the text addresses the role of parents in supporting and elaborating play, the direct connections between research and play practice, and the value of play in relation to the total development (cognitive, affective, emotional, social, and physical) of "all" children.

Praise for "Play, Development, and Early Education"
""To say that I am impressed with this text would be making an understatement of the year. We in early childhood education have needed such a text for a long time.""
Dr. Ramona E. Patterson, South Louisiana Community College

""The authors have written an extensive account showing the scope and depth of children's play including the current trends, research, and informed opinions on the importance of childhood play.""
Regina C.M. Williams, Central Ohio Technical College
