This book presents the proceedings of the Symposium on
Fluid-Structure-Sound Interactions and Control (FSSIC), (held in
Tokyo on Aug. 21-24, 2017), which largely focused on advances in
the theory, experiments on, and numerical simulation of turbulence
in the contexts of flow-induced vibration, noise and their control.
This includes several practical areas of application, such as the
aerodynamics of road and space vehicles, marine and civil
engineering, nuclear reactors and biomedical science, etc.
Uniquely, these proceedings integrate acoustics with the study of
flow-induced vibration, which is not a common practice but can be
extremely beneficial to understanding, simulating and controlling
vibration. The symposium provides a vital forum where academics,
scientists and engineers working in all related branches can
exchange and share their latest findings, ideas and innovations -
bringing together researchers from both east and west to chart the
frontiers of FSSIC.
This monograph analyses in detail the physical aspects of the
elastic waves radiation during deformation or fracture of
materials. It presents the methodological bases for the practical
use of acoustic emission device, and describes the results of
theoretical and experimental researches of evaluation of the crack
growth resistance of materials, selection of the useful AE signals.
The efficiency of this methodology is shown through the diagnostics
of various-purpose industrial objects. The authors obtain results
of experimental researches with the help of the new methods and
facilities.
This thesis investigates the sound generated by solid bodies in
steady subsonic flows with unsteady perturbations, as is typically
used when determining the noise generated by turbulent
interactions. The focus is predominantly on modelling the sound
generated by blades within an aircraft engine, and the solutions
are presented as asymptotic approximations. Key analytical
techniques, such as the Wiener-Hopf method, and the matched
asymptotic expansion method are clearly detailed. The results allow
for the effect of variations in the steady flow or blade shape on
the noise generated to be analysed much faster than when solving
the problem numerically or considering it experimentally.
This book presents selected papers from the 2nd Workshop on
"Durability of Composites in a Marine Environment", which was held
in Brest, France in August 2016. Providing an overview of the state
of the art in predicting the long-term durability of composite
marine structures, it addresses modelling water diffusion; damage
induced by water accelerated testing, including durability in
design; in-service experiences; ocean energy; and offshore
applications. Ensuring long-term durability is not only necessary
for safety reasons, but also determines the economic viability of
future marine structures, and as such, the book is essential
reading for all those involved with composites in the marine
industry, from initial design and calculation through to
manufacture and service exploitation. It also provides information
unavailable elsewhere on the mechanisms involved in degradation and
how to take account of them.
Throughout history, states have tried to create the perfect
combatant with superhuman physical and cognitive features that are
akin to those of comic book superheroes. However, the current
innovations have nothing to do with the ones from the past and
their development goes beyond a simple technological perspective.
On the contrary, they are raising the prospect of a human
enhancement revolution that will change the ways with which future
wars will be fought and may even profoundly alter the foundations
upon which our modern societies are built on. This book, which
discusses the full ethical implications of these new technologies,
is a unique contribution for students and scholars who care about
the morality of warfare. -- .
Senior level/graduate level text/reference presenting state-of-the-
art numerical techniques to solve the wave equation in
heterogeneous fluid-solid media. Numerical models have become
standard research tools in acoustic laboratories, and thus
computational acoustics is becoming an increasingly important
branch of ocean acoustic science. The first edition of this
successful book, written by the recognized leaders of the field,
was the first to present a comprehensive and modern introduction to
computational ocean acoustics accessible to students. This
revision, with 100 additional pages, completely updates the
material in the first edition and includes new models based on
current research. It includes problems and solutions in every
chapter, making the book more useful in teaching (the first edition
had a separate solutions manual). The book is intended for graduate
and advanced undergraduate students of acoustics, geology and
geophysics, applied mathematics, ocean engineering or as a
reference in computational methods courses, as well as
professionals in these fields, particularly those working in
government (especially Navy) and industry labs engaged in the
development or use of propagating models.
Single-channel hands-free teleconferencing systems are becoming
popular. In order to enhance the communication quality of these
systems, more and more stereophonic sound devices with two
loudspeakers and two microphones are deployed. Because of the
coupling between loudspeakers and microphones, there may be strong
echoes, which make real-time communication very difficult. The best
way we know to cancel these echoes is via a stereo acoustic echo
canceller (SAEC), which can be modelled as a two-input/two-output
system with real random variables. In this work, the authors recast
this problem into a single-input/single-output system with complex
random variables thanks to the widely linear model. From this new
convenient formulation, they re-derive the most important aspects
of a SAEC, including identification of the echo paths with adaptive
filters, double-talk detection, and suppression.
This book is the collection of papers from the latest International
Uranium Mining and Hydrogeology Conference (UMH VII) held in
September 2014, in Freiberg, Germany. It is divided to five
sessions: Uranium Mining, Uranium and Phosphates, Clean-up
technologies for water and soil. Uranium and daughter nuclides and
basic research and modeling. Each session covers a wide range of
related topic and provides readers with up to date research and
solutions on those matters.
This book concentrates on the subject of health monitoring
technology of Liquid Rocket Engine (LRE), including its failure
analysis, fault diagnosis and fault prediction. Since no similar
issue has been published, the failure pattern and mechanism
analysis of the LRE from the system stage are of particular
interest to the readers. Furthermore, application cases used to
validate the efficacy of the fault diagnosis and prediction methods
of the LRE are different from the others. The readers can learn the
system stage modeling, analyzing and testing methods of the LRE
system as well as corresponding fault diagnosis and prediction
methods. This book will benefit researchers and students who are
pursuing aerospace technology, fault detection, diagnostics and
corresponding applications.
Given the universal interest in whether extraterrestrial life
has developed or could eventually develop, it is vital that an
examination of planetary habitability go beyond simple assumptions.
This book has resulted from a workshop at the International Space
Science Institute (ISSI) which brought together experts to discuss
the multi-faceted problem of how the habitability of a planet
co-evolves with the geology of the surface and interior, the
atmosphere, and the magnetosphere.
The central aim of the "Sunrise "project is to understand the
structure and dynamics of the magnetic field in the solar
atmosphere. The magnetic field is the source of solar activity,
controls the space environment of the Earth and causes the
variability of solar irradiance, which may be a significant driver
of long-term changes of the terrestrial climate. Interacting with
the convective plasma flow, the magnetic field in the solar
photosphere develops intense field concentrations on scales below
100 km, which are crucial for the dynamics and energetics of the
whole solar atmosphere. These spatial scales cannot be studied
systematically from the ground because of image distortions due to
atmospheric turbulence. The balloon-borne "Sunrise" telescope has,
for the first time, provided measurements of the magnetic structure
of the solar atmosphere on its intrinsic spatial and temporal
scales. The book gives an overview about the instrumentation and
the successful flight in 2009.
All the chapters from the previous edition have been revised and
enlarged to include in most cases new fireworks formats. Four new
chapters have been added to this third edition: in a new chapter,
Chemistry of Fireworks Compositions, Dr Takeo Shimizu examines the
use of materials and binders in the manufacturing process and how
to control reactions. The chapter on Fireworks Displays, examines
the evolution of displays and modern uses throughout the world. The
new chapter on Gunpowder deals with its uses since ancient times to
date. The legislative framework for fireworks control in Great
Britain, United States, Canada and the European Union are discussed
in the new Legislation chapter. In addition, this third edition
includes a glossary with more than three hundred fireworks terms
and numerous photographs, some from the historical archives of the
Brocks Fireworks.
Space junk crashing into Earth is a real and escalating danger.
Milne provides the first synthesis of the interdisciplinary work of
the scientific community, which has been investigating how the
satellite industry can be protected from manmade and natural space
hazards. The result is an invaluable book for those concerned with
space missions and space disasters, those worried about cosmic
radiation and its effects on humans, members of the Spaceguard
defense movement, and anyone concerned with defense and
international cooperation efforts in general.
Tens of millions of objects may exist in space, ranging in size
from grains of sand to entire rocket boosters. Many fireballs seen
in the skies, often thought to be UFOs, are in fact manmade debris.
Plutonium and other highly toxic fuels from failed Russian craft
have already contaminated inhabited areas of Central Asia. Natural
hazards such as comet particles can travel at 100 times the speed
of a bullet and can severely damage satellites. There is also the
danger of spaceweather effects, such as cosmic rays, that could
interfere with a spacecraft's electronics and interrupt the global
transmission of telephones and television.
The aim of this book, with its superb step by step photographs and
detailed diagrams is to enable every owner to understand the
workings of an outboard motor (2 or 4 stroke) and be able to fix it
with relative ease. It includes: an explanation of the different
parts that make up the engine and how they interact; how fuel is
transformed into propulsion; regular maintenance and repair
worksheets to help even the most mechanically ignorant to work on
their outboard engine with confidence; the most common causes of
breakdown; troubleshooting tables to allow you to diagnose and fix
the most common engine problems and advice on how to winterize your
outboard in one short afternoon. After reading this book, your
outboard will no longer be a potential bother to you but an ally
for better boating.
When Chinese alchemists fashioned the first manmade explosion
sometime during the tenth century, no one could have foreseen its
full revolutionary potential. Invented to frighten evil spirits
rather than fuel guns or bombs,neither of which had been thought of
yet,their simple mixture of saltpeter, sulfur, and charcoal went on
to make the modern world possible. As word of its explosive
properties spread from Asia to Europe, from pyrotechnics to
battleships, it paved the way for Western exploration, hastened the
end of feudalism and the rise of the nation state, and greased the
wheels of the Industrial Revolution.With dramatic immediacy,
novelist and journalist Jack Kelly conveys both the distant time in
which the devil's distillate" rose to conquer the world, and brings
to rousing life the eclectic cast of characters who played a role
in its epic story, including Michelangelo, Edward III, Vasco da
Gama, Cortes, Guy Fawkes, Alfred Nobel, and E. I. DuPont. A
must-read for history fans and military buffs alike, Gunpowder
brings together a rich terrain of cultures and technological
innovations with authoritative research and swashbuckling style.
This book provides a broad overview of spaciousness in music
theory, from mixing and performance practice, to room acoustics,
psychoacoustics and audio engineering, and presents the derivation,
implementation and experimental validation of a novel type of
spatial audio system. Discussing the physics of musical instruments
and the nature of auditory perception, the book enables readers to
precisely localize synthesized musical instruments while
experiencing their timbral variance and spatial breadth. Offering
interdisciplinary insights for novice music enthusiasts and experts
in the field of spatial audio, this book is suitable for anyone
interested in the study of music and musicology and the application
of spatial audio mixing, or those seeking an overview of the state
of the art in applied psychoacoustics for spatial audio.
This book focuses on the theory and design of special space orbits.
Offering a systematic and detailed introduction to the hovering
orbit, spiral cruising orbit, multi-target rendezvous orbit,
initiative approaching orbit, responsive orbit and earth
pole-sitter orbit, it also discusses the concept, theory, design
methods and application of special space orbits, particularly the
design and control method based on kinematics and astrodynamics. In
addition the book presents the latest research and its application
in space missions. It is intended for researchers, engineers and
postgraduates, especially those working in the fields of orbit
design and control, as well as space-mission planning and research.
