This book compares the cultural politics of the U.S. space and Antarctic programs during the Cold War. It analyzes how culturally salient terms, especially the nationalist motif of the frontier, were used to garner public support for these strategic initiatives and, more generally, United States internationalism during this period.

This book systematically discusses nonlinear interval optimization design theory and methods. Firstly, adopting a mathematical programming theory perspective, it develops an innovative mathematical transformation model to deal with general nonlinear interval uncertain optimization problems, which is able to equivalently convert complex interval uncertain optimization problems to simple deterministic optimization problems. This model is then used as the basis for various interval uncertain optimization algorithms for engineering applications, which address the low efficiency caused by double-layer nested optimization. Further, the book extends the nonlinear interval optimization theory to design problems associated with multiple optimization objectives, multiple disciplines, and parameter dependence, and establishes the corresponding interval optimization models and solution algorithms. Lastly, it uses the proposed interval uncertain optimization models and methods to deal with practical problems in mechanical engineering and related fields, demonstrating the effectiveness of the models and methods.

Within the developed world, airlines have responded to the advice of advocates for corporate social and environmental responsibility (CSER) to use the intertwined dimensions of economics, society and environment to guide their business activities. However, disingenuously, the advocates and regulators frequently pay insufficient attention to the economics which are critical to airlines' sustainability and profits. This omission pushes airlines into the unprofitable domain of CSERplus. The author identifies alleged market inefficiencies and failures, examines CSERplus impacts on international competition and assesses the unintended consequences of the regulations. She also provides innovative ideas for future-proofing airlines. Clipped Wings is a treatise for business professionals featuring academic research as well as industry anecdotes. It is written for airlines (including their owners, employees, passengers and suppliers), airports, trade associations, policy makers, educators, students, consultants, CSERplus specialists and anyone who is concerned about the future of competitive airlines.

While international negotiations to reduce greenhouse gas (GHG) emissions have been less than satisfactory, there is a presumption that a significant level of multi-lateral commitment will be realized at some point. International air and marine travel have been left to one side in past talks because the pursuit of agreement proceeds on the basis of commitment by sovereign nations and the effects of these specific commercial activities are, by their nature, difficult to corral and assign to specific national jurisdictions. However, air travel is increasing and, unless something is done, emissions from this segment of our world economy will form a progressively larger percentage of the total, especially as emissions fall in other activities. This book focuses on fuel. The aim is to provide background in technical and policy terms, from the broadest reliable sources of information available, for the necessary discourse on society's reaction to the evolving aviation emissions profile. It considers what policy has been, why and how commercial air travel is committed to its current liquid fuel, how that fuel can be made without using fossil-source materials, and the barriers to change. It also advances some elements of policy remedies that make sense in providing an environmentally and economically sound way forward in a context that comprehends a more complete vision of sustainability than 'renewable fuels' traditionally have. The goal of Will Sustainability Fly? is to broaden and contextualize the knowledge resource available to academics, policy makers, air industry leaders and stakeholders, and interested members of the public.

This is a long-overdue volume dedicated to space trajectory optimization. Interest in the subject has grown, as space missions of increasing levels of sophistication, complexity, and scientific return - hardly imaginable in the 1960s - have been designed and flown. Although the basic tools of optimization theory remain an accepted canon, there has been a revolution in the manner in which they are applied and in the development of numerical optimization. This volume purposely includes a variety of both analytical and numerical approaches to trajectory optimization. The choice of authors has been guided by the editor's intention to assemble the most expert and active researchers in the various specialities presented. The authors were given considerable freedom to choose their subjects, and although this may yield a somewhat eclectic volume, it also yields chapters written with palpable enthusiasm and relevance to contemporary problems.

This edited volume includes thoroughly collected on sensing and control for autonomous vehicles. Guidance, navigation and motion control systems for autonomous vehicles are increasingly important in land-based, marine and aerial operations. Autonomous underwater vehicles may be used for pipeline inspection, light intervention work, underwater survey and collection of oceanographic/biological data. Autonomous unmanned aerial systems can be used in a large number of applications such as inspection, monitoring, data collection, surveillance, etc. At present, vehicles operate with limited autonomy and a minimum of intelligence. There is a growing interest for cooperative and coordinated multi-vehicle systems, real-time re-planning, robust autonomous navigation systems and robust autonomous control of vehicles. Unmanned vehicles with high levels of autonomy may be used for safe and efficient collection of environmental data, for assimilation of climate and environmental models and to complement global satellite systems. The target audience primarily comprises research experts in the field of control theory, but the book may also be beneficial for graduate students.

This book presents the relationships between tensile damage and fracture, fatigue hysteresis loops, stress-rupture, fatigue life and fatigue limit stress, and stochastic loading stress. Ceramic-matrix composites (CMCs) possess low material density (i.e., only 1/4 - 1/3 of high-temperature alloy) and high-temperature resistance, which can reduce cooling air and improve structure efficiency. Understanding the failure mechanisms and internal damage evolution represents an important step to ensure reliability and safety of CMCs. This book investigates damage and fracture of fiber-reinforced ceramic-matrix composites (CMCs) subjected to stochastic loading, including: (1) tensile damage and fracture of fiber-reinforced CMCs subjected to stochastic loading; (2) fatigue hysteresis loops of fiber-reinforced CMCs subjected to stochastic loading; (3) stress rupture of fiber-reinforced CMCs with stochastic loading at intermediate temperature; (4) fatigue life prediction of fiber-reinforced CMCs subjected to stochastic overloading stress at elevated temperature; and (5) fatigue limit stress prediction of fiber-reinforced CMCs with stochastic loading. This book helps the material scientists and engineering designers to understand and master the damage and fracture of ceramic-matrix composites under stochastic loading.

A fully illustrated study of the Nakajima Ki49 ‘Helen’, the twin-engined bomber of the Pacific War, from Japanese aviation expert George Eleftheriou.

The Nakajima Ki-49 Donryu (‘Dragon Eater’), codenamed ‘Helen’ by the Allies, was a twin-engined Japanese bomber designed to undertake daylight attacks without the protection of escort fighters. Consequently, while it was officially known as the Army Type 100 Heavy Bomber, its formidable defensive armament and armour were so heavy that they restricted the Ki-49 to payloads comparable to those of smaller medium bombers.

While only five heavy bomber sentai (regiments) were equipped with the ‘Helen’, the over 800 Ki-49s built between 1941 and 1944 saw extensive action in Burma, Papua New Guinea, the Philippines, northern India and north Australia.

In an act of desperation, a small number of ‘Helens’ were even employed, unsuccessfully, as kamikaze aircraft against US Navy warships operating off the Philippines and Okinawa.

In this fascinating book, George Eleftheriou provides a comprehensive account of the units that saw action flying the ‘Helen’, based on original Japanese sources. Also featuring high-quality photographs never published before, specially commissioned colour profile artwork, official unit histories and veteran accounts, this title is a must-have for Japanese aircraft enthusiasts.
