This book provides its reader with a good understanding of the stabilization of switched nonlinear systems (SNS), systems that are of practical use in diverse situations: design of fault-tolerant systems in space- and aircraft; traffic control; and heat propagation control of semiconductor power chips. The practical background is emphasized throughout the book; interesting practical examples frequently illustrate the theoretical results with aircraft and spacecraft given particular prominence. Stabilization of Switched Nonlinear Systems with Unstable Modes treats several different subclasses of SNS according to the characteristics of the individual system (time-varying and distributed parameters, for example), the state composition of individual modes and the degree and distribution of instability in its various modes. Achievement and maintenance of stability across the system as a whole is bolstered by trading off between individual modes which may be either stable or unstable or by exploiting areas of partial stability within all the unstable modes. The book can be used as a reference for academic research on switched systems or used by graduate students of control theory and engineering. Readers should have studied linear and nonlinear system theory and have some knowledge of switched and hybrid systems to get the most from this monograph.

Making a detailed contribution to geographies of air transport and aeromobility, this book examines the practices and processes that produce particular patterns of air transport provision both regionally and globally. In so doing, it updates the seminal contributions of Eva Taylor (1945), Kenneth Sealy (1957), Brian Graham (1995) and others to the study of air transport geography. Leading scholars in the field offer a unique insight into the key developments that have occurred in the field and the implications that these developments have had for geography, geographers, and global patterns of past, present and future air transport.Although globalization and liberalization processes have greatly expanded the demand for air transport over the last two decades, the industry has experienced several major setbacks due to economic, security, and environmental concerns. Many of these impacts have been much more pronounced in some regions, such as North America and Europe while others, such as Asia-Pacific have not been as adversely affected. Accordingly, there is a clear need to examine these recent economic and geopolitical changes from a geographical perspective given the differentiated pattern of effects from global processes. Addressing this need, this volume opens with thematic chapters covering key topics such as the historical geographies, socio-cultural mobilities, environmental externalities, urban geographies, and sustainability of the global air transport industry, followed by regional analysis of the industry in Asia-Pacific, Latin America, Greater Middle East and Africa as well as North America and Europe.

Aeronautical engineers concerned with the analysis of aircraft dynamics and the synthesis of aircraft flight control systems will find an indispensable tool in this analytical treatment of the subject. Approaching these two fields with the conviction that an understanding of either one can illuminate the other, the authors have summarized selected, interconnected techniques that facilitate a high level of insight into the essence of complex systems problems. These techniques are suitable for establishing nominal system designs, for forecasting off-nominal problems, and for diagnosing the root causes of problems that almost inevitably occur in the design process. A complete and self-contained work, the text discusses the early history of aircraft dynamics and control, mathematical models of linear system elements, feedback system analysis, vehicle equations of motion, longitudinal and lateral dynamics, and elementary longitudinal and lateral feedback control. The discussion concludes with such topics as the system design process, inputs and system performance assessment, and multi-loop flight control systems. Originally published in 1990.

Aircraft emissions currently account for ~3.5% of all greenhouse gas emissions. The number of passenger miles has increased by 5% annually despite 9/11, two wars and gloomy economic conditions. Since aircraft have no viable alternative to the internal combustion engine, improvements in aircraft efficiency and alternative fuel development become essential. This book comprehensively covers the relevant issues in green aviation. Environmental impacts, technology advances, public policy and economics are intricately linked to the pace of development that will be realized in the coming decades. Experts from NASA and industry review current technology development in green aviation that will carry the industry through 2025 and beyond. This includes increased efficiency through better propulsion systems, reduced drag airframes, advanced materials and operational changes. Clean combustion and emission control of noise, exhaust gases and particulates are also addressed through combustor design and the use of alternative fuels. Economic imperatives from aircraft lifetime and maintaince logistics dictate the drive for "drop-in" fuels, blending jet-grade and biofuel. New certification standards for such fuels are outlined. Life Cycle Assessments are used to evaluate worldwide biofuel approaches, highlighting that there is no single rational approach for sustainable buildup. In fact, unless local conditions are considered, the use of biofuels can create a net increase in environmental impact as a result of biofuel manufacturing processes. Governmental experts evaluate current and future regulations and their impact on green aviation. Sustainable approaches to biofuel development are discussed for locations around the globe, including the US, EU, Brazil, China and India.

This book presents the most serious and comprehensive study, by far, of American public perceptions about the meaning of space exploration, analyzing vast troves of questionnaire data collected by many researchers and polling firms over a span of six decades and anchored in influential social science theories. It doesn't simply report the percentages who held various opinions, but employs sophisticated statistical techniques to answer profound questions and achieve fresh discoveries. Both the Bush and the Obama administrations have cut back severely on fundamental research in space science and engineering. Understanding better what space exploration means for citizens can contribute to charting a feasible but progressive course. Since the end of the Space Race between the US and the USSR, social scientists have almost completely ignored space exploration as a topic for serious analysis and this book seeks to revive that kind of contribution. The author communicates the insights in a lucid style, not only intelligible but interesting to readers from a variety of backgrounds.

Environmental conditions and pressurized spacesuits expose astronauts to problems of fatigue during lengthy extravehicular activities, with adverse impacts especially on the dexterity, force and endurance of the hands and arms. A state-of-the-art exploration in the field of hand exoskeletons revealed that available products are unsuitable for space applications because of their bulkiness and mass. This book proposes a novel approach to the development of hand exoskeletons, based on an innovative soft robotics concept that relies on the exploitation of electroactive polymers operating as sensors and actuators, on a combination of electromyography and mechanomyography for detection of the users will and on neural networks for control. The result is a design that should enhance astronauts performance during extravehicular activities. In summary, the advantages of the described approach are a low-weight, high-flexibility exoskeleton that allows for dexterity and compliance with the users will.

The need for highly reliable and stable maneuvers for unmanned rotorcrafts (URs) class of unmanned aerial vehicle (UAVs) has increased morbidly for critical situations in real-time search-and-rescue operations for fast situational awareness (SA). A rotorcraft is a heavier-than-air flying machine that obtains its lift from rotors. SA is simply being aware of what is going on around you. This book provides basic approaches for the modeling and simulation of control systems on the basis of equations of motion for various types of models of rotorcrafts (miniature helicopter, intermediate helicopter, coaxial rotor/ducted fan mini-UAV, trirotor mini-UAV, vectored thrust mini-UAV, quadrotor mini-UAV, X4-flyer mini-UAV, eight-rotor mini-UAV) with emphasis on the modeling and simulation of realistic dynamics for fast SA. The effectiveness of the proposed research technique has been verified in field of flight simulation tests for chosen control models of the URs using software package Simulink. From the simulation results it can be seen that the UR models demonstrated an advantage in achieving good maneuverability in controlled flight during missions and good performance for fast stabilization of engines during maneuvers, consequently, fast SA with economy in energy of batteries can be asserted during missions, and the duration of missions can be longer. The principal audiences for this book are faculty members, practitioners, researchers, and graduate and postgraduate students.
