Regularized equations of motion can improve numerical integration for the propagation of orbits, and simplify the treatment of mission design problems. This monograph discusses standard techniques and recent research in the area. While each scheme is derived analytically, its accuracy is investigated numerically. Algebraic and topological aspects of the formulations are studied, as well as their application to practical scenarios such as spacecraft relative motion and new low-thrust trajectories.

This book presents theoretical and experimental investigations of mechanical behavior of solids under shock loading and highlights a multi-scale exchange process of energy and momentum between meso and macroscopic hierarchy. It also widely covers experimental approaches for the multi-scale response of solids to impacts including uniaxial strain conditions and high-velocity penetration processes. The content comprises two parts. The first part overviews modeling and theory of dynamically deformed solids from the multi-scale point of view. The second part describes experimental characterization of shock-induced solids and experimental probing of mesostructured and mesoscale dynamic processes in solids. The theory presented in the first part is then verified as it is compared with i) experiments of shock loading into different kinds of solids and ii) probed microstructure of post-shocked specimens by scanning electron microscopy, transmission electron microscopy and optical microscopy. The text is written on the basis of author's lectures at universities and thus is concisely described for postgraduate students. It is also useful for researchers who work on the theory of multi-scale mechanics of solids and engineers who work on testing materials under dynamic loading.

Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can t walk for a year? have sex? smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible for the human body to survive a bailout at 17,000 miles per hour? To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations. As Mary Roach discovers, it s possible to preview space without ever leaving Earth. From the space shuttle training toilet to a crash test of NASA s new space capsule (cadaver filling in for astronaut), Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.

This book demonstrates how to formulate the equations of mechanical systems. Providing methods of analysis of complex mechanical systems, the book has a clear focus on efficiency, equipping the reader with knowledge of algorithms that provide accurate results in reduced simulation time. The book uses Kane's method due to its efficiency, and the simple resulting equations it produces in comparison to other methods and extends it with algorithms such as order-n. Kane's method compensates for the errors of premature linearization, which are often inherent within vibrations modes found in a great deal of public domain software. Describing how to build mathematical models of multibody systems with elastic components, the book applies this to systems such as construction cranes, trailers, helicopters, spacecraft, tethered satellites, and underwater vehicles. It also looks at topics such as vibration, rocket dynamics, simulation of beams, deflection, and matrix formulation. Flexible Multibody Dynamics will be of interest to students in mechanical engineering, aerospace engineering, applied mechanics and dynamics. It will also be of interest to industry professionals in aerospace engineering, mechanical engineering and construction engineering.

This seminal monograph provides the essential guidance that we need to act as responsible ecological citizens while we expand our reach beyond Earth. The emergence of numerous national space programs along with several potent commercial presences prompts our attention to urgent environmental issues like what to do with the large mass of debris that orbits Earth, potential best practices for mining our moon, how to appropriately search for microscopic life, or whether to alter the ecology of Mars to suit humans better. This book not only examines the science and morals behind these potential ecological pitfall scenarios beyond Earth, it also provides groundbreaking policy responses founded upon ethics. These effective solutions come from a critical reframing for scientific settings of the unique moral voices of diverse Buddhists from the American ethnographic field, who together delineate sophisticated yet practical values for traveling through our solar system. Along the way, Buddhists fascinatingly supply robust environmental lessons for Earth, too. As much a work of astrobiology as it is one of religious studies, this book should appeal to anyone who is interested in space travel, our human environment in large scale, or spiritual ecology.

The design processes behind a giant leap for mankind. Neil Armstrong in a space suit on the moon remains an iconic representation of America's technological ingenuity. Few know that the Model A-7L pressure suit worn by the Apollo 11 astronauts, and the Model A-7LB that replaced it in 1971, originated at ILC Industries (now ILC Dover, LP), an obscure Delaware industrial firm.Longtime ILC space suit test engineer Bill Ayrey draws on original files and photographs to tell the dramatic story of the company's role in the Apollo Program. Though respected for its early designs, ILC failed to win NASA's faith. When the government called for new suit concepts in 1965, ILC had to plead for consideration before NASA gave it a mere six weeks to come up with a radically different design. ILC not only met the deadline but won the contract. That underdog success led to its greatest challenge: winning a race against time to create a suit that would determine the success or failure of the Apollo missions-and life or death for the astronauts. A fascinating behind-the-scenes history of a vital component of the space program, Lunar Outfitters goes inside the suit that made it possible for human beings to set foot on the Moon.

This book addresses the analysis of musical sounds from the viewpoint of someone at the intersection between physicists, engineers, piano technicians, and musicians. The study is structured into three parts. The reader is introduced to a variety of waves and a variety of ways of presenting, visualizing, and analyzing them in the first part. A tutorial on the tools used throughout the book accompanies this introduction. The mathematics behind the tools is left to the appendices. Part Two provides a graphical survey of the classical areas of acoustics that pertain to musical instruments: vibrating strings, bars, membranes, and plates. Part Three is devoted almost exclusively to the piano. Several two- and three-dimensional graphical tools are introduced to study various characteristics of pianos: individual notes and interactions among them, the missing fundamental, inharmonicity, tuning visualization, the different distribution of harmonic power for the various zones of the piano keyboard, and potential uses for quality control. These techniques are also briefly applied to other musical instruments studied in earlier parts of the book. For physicists and engineers there are appendices to cover the mathematics lurking beneath the numerous graphs and a brief introduction to Matlab (R) which was used to generate these graphs. A website accompanying the book (https://sites.google.com/site/analysisofsoundsandvibrations/) contains: - Matlab (R) scripts - mp3 files of sounds - references to YouTube videos - and up-to-date results of recent studies

Unique, cutting-edge material on structural dynamics and natural forces for offshore structures

Using the latest advances in theory and practice, Dynamics of Offshore Structures, Second Edition is extensively revised to cover all aspects of the physical forces, structural modeling, and mathematical methods necessary to effectively analyze the dynamic behavior of offshore structures. Both closed-form solutions and the Mathematica software package are used in many of the up-to-date example problems to compute the deterministic and stochastic structural responses for such offshore structures as buoys; moored ships; and fixed-bottom, cable-stayed, and gravity-type platforms.

Throughout the book, consideration is given to the many assumptions involved in formulating a structural model and to the natural forces encountered in the offshore environment. These analyses focus on plane motions of elastic structures with linear and nonlinear restraints, as well as motions induced by the forces of currents, winds, earthquakes, and waves, including the latest theories and information on wave mechanics. Topics addressed include multidegree of freedom linear structures, continuous system analysis (including the motion of cables and pipelines), submerged pile design, structural modal damping, fluid-structure-soil interactions, and single degree of freedom structural models that, together with plane wave loading theories, lead to deterministic or time history predictions of structural responses. These analyses are extended to statistical descriptions of both wave loading and structural motion.

Dynamics of Offshore Structures, Second Edition is a valuable text for students in civil and mechanical engineering programs and an indispensable resource for structural, geotechnical, and construction engineers working with offshore projects.

This book presents the first-ever comprehensive analysis of ASEAN space development programs. Written by prominent actors in the region, it goes beyond a mere expose of the history, current status and future plans of ASEAN space technology development and utilization programs, by analyzing the conditions in which a space program can be initiated in the region. It does so in two ways: on the one hand, it questions the relevance of and motivations behind the inception of space development programs in developing countries, and on the other hand, it focuses on the very specific context of ASEAN (a highly disaster-prone area shaped by unique political alliances with a distinctive geopolitical ecosystem and enormous economic potential, etc.). Last but not least, after having analyzed established and emerging space programs in the region, it provides concrete recommendations for any regional or extra-regional developing nation eager to gain a foothold in space. As such, this book offers a valuable resource for researchers and engineers in the field of space technology, as well as for space agencies and government policymakers.

As the sister book to "Introduction to Multicopter Design and Control," published by Springer in 2017, this book focuses on using a practical process to help readers to deepen their understanding of multicopter design and control. Novel tools with tutorials on multicopters are presented, which can help readers move from theory to practice. Experiments presented in this book employ: (1) The most widely-used flight platform - multicopters - as a flight platform; (2) The most widely-used flight pilot hardware - Pixhawk - as a control platform; and (3) One of the most widely-used programming languages in the field of control engi-neering - MATLAB + Simulink - as a programming language. Based on the current advanced development concept Model-Based Design (MBD)process, the three aspects mentioned above are closely linked. Each experiment is implemented in MATLAB and Simulink, and the numerical simula-tion test is carried out on a built simulation platform. Readers can upload the controller to the Pixhawk autopilot using automatic code generation technology and form a closed loop with a given real-time simulator for Hardware-In-the-Loop (HIL) testing. After that, the actual flight with the Pixhawk autopilot can be performed.

The book investigates the role of artificial input delay in approximating unknown system dynamics, referred to as time-delayed control (TDC), and provides novel solutions to current design issues in TDC. Its central focus is on designing adaptive-switching gain-based robust control (ARC) for a class of Euler-Lagrange (EL) systems with minimal or no knowledge of the system dynamics parameters. The newly proposed TDC-based ARC tackles the commonly observed over- and under-estimation issues in switching gain. The consideration of EL systems lends a practical perspective on the proposed methods, and each chapter is supplemented by relevant experimental data. The book offers a unique resource for researchers in the areas of ARC and TDC alike, and covers the state of the art, new algorithms, and future directions.
