This book basically involves the study of flight parameters, wing beat frequency, moment of inertia, and wing movements for developing various aerodynamic forces which have been calculated. The book is intended for biologists, physicists, nanotechnologists, and aerospace engineers. Resilin, an elastic polymer (4 ) which is present at the base of insect, plays a major role in Neurogenic and Myogenic insect flyers and influences the physiology of flight muscles. Leading edge vortex (LEV) is a special feature of insect flight. Insect wings have stalling angle above 60 degrees as compared to a man-made aeroplane stalling angle which is 16 degree. Reynolds number, the knowledge of LEV, and detailed study of moment of inertia help in developing flapping flexible wings for micro-aerial-vehicles. This book serves as an interface between biologists and engineers interested to develop biomimicking micro-aerial-vehicles. The contents of this book is useful to researchers and professionals alike.

For introductory course in space flight dynamics. A self-contained, integrated introduction to the performance aspects of flight - how to get into space, how to get around in space, and how to return to Earth or land on another planet (as opposed to specialized areas of life support, guidance and control, or communications).

Comets consist of the most primitive material in the solar system and to understand the earliest epoch of solar system formation, we must investigate the nature of this material. Much of what we know of comets presently comes from remote sensing using Earth-based telescopes. The Rosetta mission is poised to make a dramatic advance in our understanding of comets.

This book demonstrates various types of deepwater risers with different motion equations and boundary conditions depending on their different structural configurations. It also discusses the hydrodynamic analysis methods of different deepwater risers. It provides new force and structure models in time and frequency domains of vortex induced force, including that for a downstream riser of the tandem riser, and the rigid oscillating model for steel catenary riser. The highlights of this book are the analysis methods of the rigid oscillating mode of steel catenary riser and the coupling iteration for top-tensioned riser with pipe-in-pipe configuration. This book is interesting and useful to a wide readership in the various fields of ocean engineering and offshore oil & gas development.

This book provides recommendations for thermal and structural modelling of spacecraft structures for predicting thermoelastic responses. It touches upon the related aspects of the finite element and thermal lumped parameter method. A mix of theoretical and practical examples supports the modelling guidelines. Starting from the system needs of instruments of spacecraft, the reader is supported with the development of the practical requirements for the joint development of the thermal and structural models. It provides points of attention and suggestions to check the quality of the models.The temperature mapping problem, typical for spacecraft thermoelastic analysis, is addressed. The principles of various temperature mapping methods are presented. The prescribed average temperature method, co-developed by the authors, is discussed in detail together with its spin-off to provide high quality conductors for thermal models. The book concludes with the discussion of the application of uncertainty assessment methods. The thermoelastic analysis chain is computationally expensive. Therefore, the 2k+1 point estimate method of Rosenblueth is presented as an alternative for the Monte Carlo Simuation method, bringing stochastic uncertainty analysis in reach for large thermoelastic problems.

This text presents the most recent research on fracture and damage of concrete and rock. It provides an improved understanding of the basic physical and mechanical principles of fracture mechanics in these materials with a strong view towards applications in construction engineering and mining engineering. It forms the proceedings of the international conference held in Vienna in November 1992. The background to the book comes from three main areas: fatigue and ageing of complex concrete structures have been responsible both for loss of life and for expenditure running into billions of dollars in recent decades; lack of virgin building land and high property values in cities and urban areas have led to more demolition and recycling of concrete structures, and related environmental problems; and more engineering structures are being built on and in rock mass of low quality and difficult terrain. Rock fracture mechanics has matured to a fully recognized discipline and is now being applied to problems of excavation, tunnelling, blasting and anchoring. FDCR Conferences provide a forum for international, interdisciplinary co-operation and exchange of ideas and experience between scienti

This definitive guide covers the design and application of absorbers and diffusers in acoustics. Surface diffusion is a relatively young subject area, and diffuser design, application and characterisation are often not well understood. Although there is greater knowledge of absorption, it is also informed by new research. As two of the main design tools for altering the acoustic conditions of rooms, the correct use of absorbers and diffusers is important to the creation of quality acoustics. This text details the evolution and the current state of the art in diffuser and absorber research and application. It covers a range of practical and theoretical aspects, with extensive examples of installations and case studies to cater to practitioners working in the measurement, modelling and design of rooms, semi-enclosed spaces as well as in noise control. It is also invaluable for students and researchers wanting a grounding in acoustic treatment, as well as understanding the latest developments. All chapters have been revised and brought up to date in this new edition, with new applications, absorbers and diffusers featured. Sustainability, portable vocal booths, and fast time domain models for diffusers are just a few of the new sections. Improved techniques for measurement and prediction are included, as well as bringing old methods up-to-date with the latest refinements from standards and research. Most of the prediction methods in the book are now linked to open source implementations and downloadable MATLAB scripts, enabling readers to exploit the knowledge in this book more readily in design and research.

This book presents the signal processing algorithms that have been developed to process the signals acquired by a spherical microphone array. Spherical microphone arrays can be used to capture the sound field in three dimensions and have received significant interest from researchers and audio engineers. Algorithms for spherical array processing are different to corresponding algorithms already known in the literature of linear and planar arrays because the spherical geometry can be exploited to great beneficial effect. The authors aim to advance the field of spherical array processing by helping those new to the field to study it efficiently and from a single source, as well as by offering a way for more experienced researchers and engineers to consolidate their understanding, adding either or both of breadth and depth. The level of the presentation corresponds to graduate studies at MSc and PhD level. This book begins with a presentation of some of the essential mathematical and physical theory relevant to spherical microphone arrays, and of an acoustic impulse response simulation method, which can be used to comprehensively evaluate spherical array processing algorithms in reverberant environments. The chapter on acoustic parameter estimation describes the way in which useful descriptions of acoustic scenes can be parameterized, and the signal processing algorithms that can be used to estimate the parameter values using spherical microphone arrays. Subsequent chapters exploit these parameters including in particular measures of direction-of-arrival and of diffuseness of a sound field. The array processing algorithms are then classified into two main classes, each described in a separate chapter. These are signal-dependent and signal-independent beamforming algorithms. Although signal-dependent beamforming algorithms are in theory able to provide better performance compared to the signal-independent algorithms, they are currently rarely used in practice. The main reason for this is that the statistical information required by these algorithms is difficult to estimate. In a subsequent chapter it is shown how the estimated acoustic parameters can be used in the design of signal-dependent beamforming algorithms. This final step closes, at least in part, the gap between theory and practice.

Produced sand causes a lot of problems. From that reasons sand production must be monitored and kept within acceptable limits. Sand control problems in wells result from improper completion techniques or changes in reservoir properties. The idea is to provide support to the formation to prevent movement under stresses resulting from fluid flow from reservoir to well bore. That means that sand control often result with reduced well production. Control of sand production is achieved by: reducing drag forces (the cheapest and most effective method), mechanical sand bridging (screens, gravel packs) and increasing of formation strength (chemical consolidation). For open hole completions or with un-cemented slotted liners/screens sand failure will occur and must be predicted. Main problem is plugging. To combat well failures due to plugging and sand breakthrough Water-Packing or Shunt-Packing are used.

This Festschrift dedicated to the 60th birth anniversary of Prof. Sandip K. Chakrabarti, a well-known Indian astrophysicist, presents a collection of contributions by about fifty scientists who work on diverse topics in contemporary astrophysics and space science including new and low-cost balloon borne experiments, planetary science, astrochemistry and the origin of life, ionospheric research and earthquake predictions, relativistic astrophysics around black holes, and finally, the observational signatures and radiative properties of compact objects. All the authors are well known scholars in their respective subject and are all PhD students of Prof. Sandip K. Chakrabarti. The book demonstrates a two-dimensional evolution of research areas triggered by Sandip Chakrabarti over the past few decades. The first dimension represents the evolution and diversification of Chakrabarti's own research in which new students were trained. A second dimension arises from the evolution of the research topics pursued by Chakrabarti's fifty odd doctoral students, many of whom have become renowned scientists in their own right, after starting with a certain subject under Chakrabarti and then migrating to completely new subjects with dexterity. The editors have compiled and edited the articles appropriately to some extent to suit the spirit of this Festschrift on the one hand and to keep balance in diverse topics on the other. Thus this volume also provides an overview for whosoever wishes to enter the important subjects of compact objects, astrochemistry, ionospheric science or space exploration in near space. New graduates, PhD scholars, teachers and researchers will benefit from this volume. Moreover it is a record of tremendous success of a school in a range of vast topics.

The last two decades have seen unprecedented developments in marine science and technology. Large scale, international long-term scientific programmes have emerged for monitoring the state of the ocean environment and the rapid development of the offshore oil industry has provided the technological means for a range of other maritime developments. The purpose of this book is to review key developments in this field. Three major themes are developed throughout the book: the key importance of technical developments in ocean management; the application of these developments to specific sea uses ranging from fish farming to the deep sea disposal of industrial waste; and the long term general issues raised - and to some extent solved - by science and technology. This book should be of interest to students and professionals involved in maritime studies, oceanography, offshore engineering and environmental science.

"Of all the men who attacked the flying problem in the 19th century, Otto Lilienthal was easily the most important. His greatness appeared in every phase of the problem. No one equaled him in power to draw new recruits to the cause; no one equaled him in fullness and dearness of understanding of the principles of flight; no one did so much to convince the world of the advantages of curved wing surfaces; and no one did so much to transfer the problem of human flight to the open air where it belonged." These words were spoken by Wilbur Wright, who successfully accomplished the first powered flight together with his brother Orville in 1903 on the sand dunes of the Outer Banks off the coast of North Carolina. Wilbur was talking about the most important of their predecessors, Otto Lilienthal. Lilienthal attracted worldwide attention due to the spectacular photographs showing him in flight, made possible by technology that had only just been developed by him. This fortuitous union between a pioneer of aviation and the pioneers of so-called "instantaneous photography" is responsible for the immense contemporary popularity of Lilienthal's flights around the globe, the first ever free flights performed by man. This book traces the life of the German aviation pioneer, focusing on the designs of his many aircraft and the photographic documentation that has survived. The presentation ends with a remarkable research project conducted by one of the authors, right up to and including his own training exercises with Lilienthal's "normal soaring apparatus" and "large biplane". This project offered new insight into Lilienthal's work, and also led to a spectacular aerial meeting of Lilienthal's 1895 biplane and the Wright brothers' 1902 biplane at a historic location on the Outer Banks. The book provides access to video material, largely stemming from this project.

Perhaps no one in history has played the role of scientist as celebrity with as much skill--and as much deception--as Wernher von Braun. America's leading rocket expert and most enthusiastic advocate of space travel, he had a closet full of secrets that would have shocked his colleagues and millions of admirers if they had been told during his lifetime. "Wernher von Braun: The Man Who Sold the Moon" is the first critical biography of the young German aristocrat who created Hitler's most advanced terror weapon, the V-2 rocket, and who came to the U.S. under the Army's Project Paperclip to develop missiles as a central weapon of the Cold War. The book reveals that factions of the U.S. Army, in their zeal to have von Braun's team of scientists working for American interests, covered up what they knew about his complicity in Nazi causes and abetted him in the perpetuation of the myth he carefully created about his past.

Declassified Army documents and war crime transcripts, as well as the discovery of Europe of Dora concentration camp survivors' accounts, and von Braun's published writings and personal papers, have enabled biographer Dennis Piszkiewicz to document von Braun's career more fully than any previous historian. The man who tirelessly promoted space travel, worked with NASA to collaborate with Walt Disney creating television programs and the Tomorrowland section of Disneyland, and put the first astronauts on the moon, was actually a member of the Nazi party, held a rank in the SS equivalent to that of Major, and was an accomplice in the use of slave labor from the Dora concentration camp to produce his V-2 rocket. When the Third Reich collapsed, von Braun unashamedly switched his allegiance to the victor, and adroitly distanced himself from his Nazi partners. By going on to promote NASA and sell the American people on his dreams of space exploration, he became the man who sold the moon--a man who began his brilliant career by selling his soul to the Nazis.

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.
