Based on the research activities of the six-year NASA human performance modeling project, Human Performance Modeling in Aviation provides an in-depth look at cognitive modeling of human operators for aviation problems. This book presents specific solutions to aviation safety problems and explores methods for integrating human performance modeling into the aviation design process. The text compares the application of five different models to two classes of aviation problems: pilot navigation errors during airport taxi operations and approach and landing performance with synthetic vision systems. This results in a comprehensive summary of the capabilities of each model and of the field in general.

With air travel a regular part of daily life in North America, we tend to take the infrastructure that makes it possible for granted. However, the systems, regulations, and technologies of civil aviation are in fact the product of decades of experimentation and political negotiation, much of it connected to the development of the airmail as the first commercially sustainable use of airplanes. From the lighted airways of the 1920s through the radio navigation system in place by the time of World War II, this book explores the conceptualization and ultimate construction of the initial US airways systems.The daring exploits of the earliest airmail pilots are well documented, but the underlying story of just how brick-and-mortar construction, radio research and improvement, chart and map preparation, and other less glamorous aspects of aviation contributed to the system we have today has been understudied. Flying the Beam traces the development of aeronautical navigation of the US airmail airways from 1917 to 1941. Chronologically organized, the book draws on period documents, pilot memoirs, and firsthand investigation of surviving material remains in the landscape to trace the development of the system. The author shows how visual cross-country navigation, only possible in good weather, was developed into all-weather "blind flying." The daytime techniques of "following railroads and rivers" were supplemented by a series of lighted beacons (later replaced by radio towers) crisscrossing the country to allow nighttime transit of long-distance routes, such as the one between New York and San Francisco. Although today's airway system extends far beyond the continental US and is based on digital technologies, the way pilots navigate from place to place basically uses the same infrastructure and procedures that were pioneered almost a century earlier. While navigational electronics have changed greatly over the years, actually "flying the beam" has changed very little.

Promotes a green approach to chemistry and chemical engineering for a sustainable planet With this text as their guide, students will gain a new outlook on chemistry and engineering. The text fully covers introductory concepts in general, organic, inorganic, and analytical chemistry as well as biochemistry. At the same time, it integrates such concepts as greenhouse gas potential, alternative and renewable energy, solvent selection and recovery, and ecotoxicity. As a result, students learn how to design chemical products and processes that are sustainable and environmentally friendly. Green Chemistry and Engineering presents the green approach as an essential tool for tackling problems in chemistry. A novel feature of the text is its integration of introductory engineering concepts, making it easier for students to move from fundamental science to applications. Throughout this text, the authors integrate several features to help students understand and apply basic concepts in general chemistry as well as green chemistry, including: Comparisons of the environmental impact of traditional chemistry approaches with green chemistry approaches Analyses of chemical processes in the context of life-cycle principles, demonstrating how chemistry fits within the complex supply chain Applications of green chemistry that are relevant to students' lives and professional aspirations Examples of successful green chemistry endeavors, including Presidential Green Chemistry Challenge winners Case studies that encourage students to use their critical thinking skills to devise green chemistry solutions Upon completing this text, students will come to understand that chemistry is not antithetical to sustainability, but rather, with the application of green principles, chemistry is the means to a sustainable planet.

This unique volume attempts to answer one of mankind's oldest puzzles -- why the moon appears to be larger and closer on the horizon than when it is high in the sky. Over the centuries, many viable solutions have been proposed for this psychological phenomenon. The Moon Illusion presents papers by major theorists striving to explain the illusion and providing commentaries on the works of others. Research on the moon illusion has been scattered throughout journals in many disciplines including philosophy, physiology, physics, and psychology. As the first publication to present a comprehensive treatment of the problem, this book is of vital interest to professionals whose major concern is visual perception, experimental psychology, or the neurosciences. Of additional interest to those whose focus is physics or astronomy.
