Spacecraft TT&C and Information Transmission Theory and
Technologies introduces the basic theory of spacecraft TT&C
(telemetry, track and command) and information transmission.
Combining TT&C and information transmission, the book presents
several technologies for continuous wave radar including
measurements for range, range rate and angle, analog and digital
information transmissions, telecommand, telemetry, remote sensing
and spread spectrum TT&C. For special problems occurred in the
channels for TT&C and information transmission, the book
represents radio propagation features and its impact on orbit
measurement accuracy, and the effects caused by rain attenuation,
atmospheric attenuation and multi-path effect, and polarization
composition technology. This book can benefit researchers and
engineers in the field of spacecraft TT&C and communication
systems. Liu Jiaxing is a professor at The 10th Institute of China

Shallow water acoustics (SWA), the study of how low and medium
frequency sound propagates and scatters on the continental shelves
of the worlds oceans, has both technical interest and a large
number of practical applications. Technically, shallow water poses
an interesting medium for the study of acoustic scattering, inverse
theory, and propagation physics in a complicated oceanic waveguide.
Practically, shallow water acoustics has interest for geophysical
exploration, marine mammal studies, and naval applications.
Additionally, one notes the very interdisciplinary nature of
shallow water acoustics, including acoustical physics, physical
oceanography, marine geology, and marine biology. In this
specialized volume the authors, all of whom have extensive at-sea
experience in US and Russian research efforts, have tried to
summarize the main experimental, theoretical, and computational
results in shallow water acoustics, with an emphasis on providing
physical insight into the topics presented.
"Load and Global Response of Ships" gives an introductory
background to naval architecture statistics and strength of
materials. Each subject is treated in detail; starting from the
first principle. The aim of this title was to derive and present
the necessary theoretical framework for predicting the extreme
loads and the corresponding hull girder stresses that a ship may be
subjected to during its operational lifetime.
Although some account is given to reliability analysis, the
present treatment has to be supplemented with methods for detailed
stress evaluation and for structural strength assessment before a
complete structural reliability analysis can be carried out.
The classification societies have issued rules and regulations for
a proper structural analysis of a ship and selection of the
scantlings. Previously, those rules rather explicitly gave formulae
for the thickness of the hull plantings, the size of the stiffeners
etc. Such empirical rules must necessarily be rather conservative
in order to apply to a large variety of ships. With the advent of
powerful computers, the rules have changed. Today, the naval
architect can perform the structural analysis using mainly rational
methods based on first principles. The classification society may
then specify proper safety factors against local global failure
modes, taking into account the consequences of failure and the
analysis procedure used. A cruder method of analysis then
necessitates a larger safety factor. Therefore the effort made by
the experienced naval architect to perform a detailed structural
analysis will be returned not just by a rational structural
arrangement but also often in lower weight of the ship and thus a
higher payload throughout the operational lifetime of the ship.
This analysis has attempted to make explicit one way in which
designers limit the design space by creating rules to which they
expect users to adhere. It is also an attempt to encourage
designers to reconsider the 'rules of use' that they have used in
their designs, so as to reconceptualise potential usage. This can
help design behaviour where rule use is not blindly followed.
By making these rules visible, it is possible to expose the
limitations of current technology, and development design solutions
that do not restrict use to the 'normal' case of action. Rules are
useful to designers because they are simplifications of activity.
Rules encode the normal case, and these are simplistic
representations of work that are, in many cases, accurate enough
for the purpose of design. However, encoding behaviour in rules has
dangers in that they do not encompass the whole range of behaviours
that can be performed. Using examples, this title shows that being
able to break rules means that people are able to engage in a
richer more flexible set of actions (and therefore more appropriate
to contingency) than when they are constrained to a limited range.
This book makes good background reading for much of modern
magnetospheric physics. Its origin was a Festspiel for Professor
Jim Dungey, former professor in the Physics Department at Imperial
College on the occasion of his 90th birthday, 30 January 2013.
Remarkably, although he retired 30 years ago, his pioneering and,
often, maverick work in the 50's through to the 70's on solar
terrestrial physics is probably more widely appreciated today than
when he retired. Dungey was a theoretical plasma physicist. The
book covers how his reconnection model of the magnetosphere evolved
to become the standard model of solar-terrestrial coupling.
Dungey's open magnetosphere model now underpins a holistic picture
explaining not only the magnetic and plasma structure of the
magnetosphere, but also its dynamics which can be monitored in real
time. The book also shows how modern day simulation of solar
terrestrial coupling can reproduce the real time evolution of the
solar terrestrial system in ways undreamt of in 1961 when Dungey's
epoch-making paper was published. Further contributions on current
Earth magnetosphere research and space plasma physics included in
this book show how Dungey's basic ideas have remained explanative
50 years on. But the Festspiel also introduced some advances that
possibly Dungey had not foreseen. One of the contributions
presented in this book is on the variety of magnetospheres of the
solar system which have been seen directly during the space age,
discussing the variations in spatial scale and reconnection time
scale and comparing them in respect of Earth, Mercury, the giant
planets as well as Ganymede.
"...a comprehensive and well written book, which...will be useful
reading for both researchers entering the field and experienced
specialists looking for new ideas....a valuable and long-lasting
contribution to experimental mechanics." - Stepan Lomov, KU Leuven
This expert volume, an enhanced Habilitation thesis by the head of
the Materials Testing Research Group at the University of Augsburg,
provides detailed coverage of a range of inspection methods for
insitu characterization of fiber-reinforced composites. The failure
behavior of fiber reinforced composites is a complex evolution of
microscopic damage phenomena. Beyond the use of classical testing
methods, the ability to monitor the progression of damage insitu
offers new ways to interpret the materials failure modes. Methods
covered include digital image correlation, acoustic emission,
electromagnetic emission, computed tomography, thermography,
shearography, and promising method combinations. For each method,
the discussion includes operational principles and practical
applications for quality control as well as thoughtful assessment
of the method's strengths and weakness so that the reader is
equipped to decide which method or methods are most appropriate in
a given situation. The book includes extensive appendices covering
common experimental parameters influencing comparability of
acoustic emission measurements; materials properties for modeling;
and an overview of terms and abbreviations.
The authors review the past 20 years work in this field, and
bring together for the first time details of the technology
available and being developed to provide totally reusable launch
vehicles for the future exploitation and exploration of space.
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 provides an introduction to the physics of interstellar
gas in the Galaxy. It deals with the diffuse interstellar medium
which supplies a complex environment for exploring the neutral gas
content of a galaxy like the Milky Way and the techniques necessary
for studying this non-stellar component. After an initial
exposition of the phases of the interstellar medium and the role of
gas in a spiral galaxy, the authors discuss the transition from
atomic to molecular gas. They then consider basic radiative
transfer and molecular spectroscopy with particular emphasis on the
molecules useful for studying low-density molecular gas.
Observational techniques for investigating the gas and the dust
component of the diffuse interstellar medium throughout the
electromagnetic spectrum are explored emphasizing results from the
recent Herschel and Planck missions. A brief exposition on dust in
the diffuse interstellar medium is followed by a discussion of
molecular clouds in general and high-latitude molecular clouds in
particular. Ways of calibrating CO observations with the molecular
hydrogen content of a cloud are examined along with the dark
molecular gas controversy. High-latitude molecular clouds are
considered in detail as vehicles for applying the techniques
developed in the book. Given the transient nature of diffuse and
translucent molecular clouds, the role of turbulence in the origin
and dynamics of these objects is examined in some detail. The book
is targeted at graduate students or postdocs who are entering the
field of interstellar medium studies.
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.
Following the first comprehensive transdisciplinary dialogue on
humans in outer space which resulted in "Humans in Outer Space -
Interdisciplinary Odysseys", the European Science Foundation (ESF),
the European Space Agency (ESA), and the European Space Policy
Institute (ESPI) have continued and deepened this transdisciplinary
dialogue, which can now be found in Humans in Outer Space -
Interdisciplinary Perspectives. Going further than regarding humans
as better-than-robot tools for exploration, it investigates the
human quest for odysseys beyond Earth's atmosphere and reflects on
arising issues related to Europe's role among the States conducting
human exploration. It provides perspectives related to governance,
management of space exploration, space settlements, the role of
astronauts in the future as well as related to the encounter of
extraterrestrial life.
Aero and Vibroacoustics of Automotive Turbochargers is a topic
involving aspects from the working fields of thermodynamics of
turbomachinery, aerodynamics, rotordynamics, and noise propagation
computation. In this broadly interdisciplinary subject,
thermodynamics of turbomachinery is used to design the turbocharger
and to determine its operating conditions. Aerodynamics is needed
to study the compressor flow dynamics and flow instabilities of
rotating stall and surge, which can produce growling and
whining-type noises. Rotordynamics is necessary to study rotor
unbalance and self-excited oil-whirl instabilities, which lead to
whistling and constant tone-type noises in rotating floating
oil-film type bearings. For the special case of turbochargers using
ball bearings, some high-order harmonic and wear noises also
manifest in the rotor operating range. Lastly, noise propagation
computation, based on Lighthill's analogy, is required to
investigate airborne noises produced by turbochargers in passenger
vehicles. The content of this book is intended for advanced
undergraduates, graduates in mechanical engineering, research
scientists and practicing engineers who want to better understand
the interactions between these working fields and the resulting
impact on the interesting topic of Aero and Vibroacoustics of
Automotive Turbochargers.
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 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.
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.
