How the public image of the Soviet cosmonaut was designed and reimagined over timeIn this book, Cathleen Lewis discusses how the public image of the Soviet cosmonaut developed beginning in the 1950s and the ways this icon has been reinterpreted throughout the years and in contemporary Russia. Compiling material and cultural representations of the cosmonaut program, Lewis provides a new perspective on the story of Soviet spaceflight, highlighting how the government has celebrated figures such as Yuri Gagarin and Valentina Tereshkova through newspapers, radio, parades, monuments, museums, films, and even postage stamps and lapel pins. Lewis's analysis shows that during the Space Race, Nikita Khrushchev mobilized cosmonaut stories and images to symbolize the forward-looking Soviet state and distract from the costs of the Cold War. Public perceptions shifted after the first Soviet spaceflight fatality and failure to reach the Moon, yet cosmonaut imagery was still effective propaganda, evolving through the USSR's collapse in 1991 and seen today in Vladimir Putin's government cooperation for a film on the 1985 rescue of the Salyut 7 space station. Looking closely at the process through which Russians continue to reexamine their past, Lewis argues that the cultural memory of spaceflight remains especially potent among other collective Soviet memories.

The author's approach is one of continuum models of the aerodynamic flow interacting with a flexible structure whose behavior is governed by partial differential equations. Both linear and nonlinear models are considered although much of the book is concerned with the former while keeping the latter clearly in view. A complete chapter is also devoted to nonlinear theory. The author has provided new insights into the classical inviscid aerodynamics and raises novel and interesting questions on fundamental issues that have too often been neglected or forgotten in the development of the early history of the subject. The author contrasts his approach with discrete models for

the unsteady aerodynamic flow and the finite element model for the structure. Much of the aeroelasticity has been developed with applications formerly inmind because of its enormous consequences for the safety of aircraft.

Aeroelastic instabilities such as divergence and flutter and aeroelastic responses to gusts can pose a significant hazard to the aircraft and impact its performance. Yet, it is now recognized that

there are many other physical phenomena that have similar characteristics ranging from flows around flexible tall buildings and long span bridges, alternate energy sources such as electric power generation by smart structures to flows internal to the human body.

From the foreword:

"For the theorist and applied mathematician who wishes an introduction to this fascinating subject as well as for the experienced aeroelastician who is open to new challenges and a fresh viewpoint,

this book and its author have much to offer the reader."

This book provides a systematic and standardized approach based on the authors' over 30 years of research experience with weight function methods, as well as the relevant literature. Fracture mechanics has become an indispensable tool for the design and safe operation of damage-tolerant structures in many important technical areas. The stress intensity factor-the characterizing parameter of the crack tip field-is the foundation of fracture mechanics analysis. The weight function method is a powerful technique for determining stress intensity factors and crack opening displacements for complex load conditions, with remarkable computational efficiency and high accuracy. The book presents the theoretical background of the weight function methods, together with a wealth of analytical weight functions and stress intensity factors for two- and three-dimensional crack geometries; many of these have been incorporated into national, international standards and industrial codes of practice. The accuracy of the results is rigorously verified, and various sample applications are provided. Accordingly, the book offers an ideal reference source for graduate students, researchers, and engineers whose work involves fracture and fatigue of materials and structures, who need not only stress intensity factors themselves but also efficient and reliable tools for obtaining them.

This book presents a systematic introduction to particle damping technologies, which can be used to effectively mitigate seismic-induced and wind-induced vibration in various structures. Further, it offers comprehensive information on the latest research advances, e.g. a refined simulation model based on the discrete element method and a simplified simulation model based on equivalent principles. It then intensively studies the vibration attenuation effects of particle dampers subjected to different dynamic loads; in this context, the book proposes a new damping mechanism and "global'' measures that can be used to evaluate damping performance. Moreover, the book uses the shaking table test and wind tunnel test to verify the proposed simulation methods, and their satisfactory damping performance is confirmed. To facilitate the practical engineering application of this technology, optimization design guidelines for particle impact dampers are also provided. In closing, the book offers a preliminary exploration of semi-active particle damping technology, which holds great potential for extension to other applications in which the primary system is subjected to non-stationary excitations.

This veteran analyst offers an appraisal of investment opportunities in a wide array of space-related activities. NASA will no longer be a major factor in the commercialization of space. . . . There are a few futuristic projections, such as mining asteroids by robots and collecting antimatter, but the author is more concerned with the application of current or near-future high technology, i.e., products like ELVs (inexpensive expendable launch vehicles), and services with demonstrably large market potential, such as a remote sensing satellite network that could be subsribed to by every personal computer owner on earth. "Choice"

The Challenger disaster, according to this provocative new book, signaled the end of NASA's domination of space--at least for commercial purposes. David P. Gump claims that after two decades of doldrums, the space industry is about to enter the new era of free enterprise. NASA's tediously slow pace, writes Gump, will be leapfrogged by dozens of private initiatives that will create a new orbital economy. "Space Enterprise" outlines the parameters for the development and growth of a new space industry fueled by the competitiveness of private enterprise. This historic shift from government to private leadership in space is evidenced in the many large and small companies already planning private space stations and battling to create their own launches at far lower costs than NASA's projects.

The book begins with an engrossing account of the causes of the Challenger failure. Gump goes on to demonstrate how NASA's failure opened the door to space as the next economic frontier. On-orbit research labs will create new medicines, electronic crystals, and superconducting alloys. Solar power satellites, built with materials mined on the Moon, will provide low-cost nonpolluting electricity to cities on Earth. "Space Enterprise" is a map to the opportunities of the new space age.

This book focuses on the theory and design methods for guidance, navigation, and control (GNC) in the context of spacecraft rendezvous and docking (RVD). The position and attitude dynamics and kinematics equations for RVD are presented systematically in accordance with several different coordinate systems, including elliptical orbital frame, and recommendations are supplied on which of these equations to use in different phases of RVD. The book subsequently explains the basic principles and relative navigation algorithms of RVD sensors such as GNSS, radar, and camera-type RVD sensors. It also provides guidance algorithms and schemes for different phases of RVD, including the latest research advances in rapid RVD. In turn, the book presents a detailed introduction to intelligent adaptive control and proposes corresponding theoretical approaches to thruster configuration and control allocation for RVD. Emphasis is placed on the design method of active and passive trajectory protection in different phases of RVD, and on the safety design of the RVD mission as a whole. For purposes of verification, the Shenzhou spacecraft's in-orbit flight mission is introduced as well. All issues addressed are described and explained from basic principles to detailed engineering methods and examples, providing aerospace engineers and students both a basic understanding of, and numerous practical engineering methods for, GNC system design in RVD.

This innovative monograph explores a new mathematical formalism in higher-order temporal logic for proving properties about the behavior of systems. Developed by the authors, the goal of this novel approach is to explain what occurs when multiple, distinct system components interact by using a category-theoretic description of behavior types based on sheaves. The authors demonstrate how to analyze the behaviors of elements in continuous and discrete dynamical systems so that each can be translated and compared to one another. Their temporal logic is also flexible enough that it can serve as a framework for other logics that work with similar models. The book begins with a discussion of behavior types, interval domains, and translation invariance, which serves as the groundwork for temporal type theory. From there, the authors lay out the logical preliminaries they need for their temporal modalities and explain the soundness of those logical semantics. These results are then applied to hybrid dynamical systems, differential equations, and labeled transition systems. A case study involving aircraft separation within the National Airspace System is provided to illustrate temporal type theory in action. Researchers in computer science, logic, and mathematics interested in topos-theoretic and category-theory-friendly approaches to system behavior will find this monograph to be an important resource. It can also serve as a supplemental text for a specialized graduate topics course.
