This book addresses space science and communication - one of the
main pillars of space science sustainability, an area that has
recently become of great importance. In this regard, research and
development play a crucial role in sustainability development.
However, obtaining essential data in the physical world to
interpret the universe and to predict what could happen in the
future is a challenging undertaking. Accordingly, providing valid
information to understand trends, evaluate needs, and create
sustainable development policies and programs in the best interest
of all the people is indispensable. This book was prepared in
conjunction with the fifth meeting of the 2017 International
Conference on Space Science and Communication (IconSpace2017), held
in Kuala Lumpur, Malaysia on 3-5 May 2017 to introduce graduate
stuandents, researchers, lecturers, engineers, geospatialists,
meteorologists, climatologists, astronomers and practitioners to
the latest applications of space science, telecommunications,
meteorology, remote sensing and related fields. The individual
papers discuss a broad range of space science and technology
applications, e.g. the formation of global warming from space,
environmental and remote sensing, communication systems, and smart
materials for space applications.
This is a follow-on book to the introductory textbook "Physics of
the Solar Corona" previously published in 2004 by the same author,
which provided a systematic introduction and covered mostly
scientific results from the pre-2000 era. Using a similar structure
as the previous book the second volume provides a seamless
continuation of numerous novel research results in solar physics
that emerged in the new millennium (after 2000) from the new solar
missions of RHESSI, STEREO, Hinode, CORONAS, and the Solar Dynamics
Observatory (SDO) during the era of 2000-2018. The new solar space
missions are characterized by unprecedented high-resolution
imaging, time resolution, spectral capabilities, stereoscopy and
tomography, which reveal the intricate dynamics of
magneto-hydrodynamic processes in the solar corona down to scales
of 100 km. The enormous amount of data streaming down from SDO in
Terabytes per day requires advanced automated data processing
methods. The book focuses exclusively on new research results after
2000, which are reviewed in a comprehensive manner, documented by
over 3600 literature references, covering theory, observations, and
numerical modeling of basic physical processes that are observed in
high-temperature plasmas of the Sun and other astrophysical
objects, such as plasma instabilities, coronal heating, magnetic
reconnection processes, coronal mass ejections, plasma waves and
oscillations, or particle acceleration.
This authoritative new resource explores the communications aspect
of electronic warfare and presents the major technical issues that
drive the practice of land EW to help practitioners with their work
in the field. The book offers a detailed understanding of the
structure of tactical communications electronic warfare systems,
the relationship between these systems and their targets, and the
likely future development path of land electronic warfare. Written
in a clear, easy-to-understand style, with accessible descriptions
of tactical communications EW techniques, the book is a useful
reference for technical and non-technical professionals alike.
This book provides a comprehensive introduction to the theory and
practice of spherical microphone arrays, and was written for
graduate students, researchers and engineers who work with
spherical microphone arrays in a wide range of applications. The
new edition includes additions and modifications, and references
supplementary Matlab code to provide the reader with a
straightforward start for own implementations. The book is also
accompanied by a Matlab manual, which explains how to implement the
examples and simulations presented in the book. The first two
chapters provide the reader with the necessary mathematical and
physical background, including an introduction to the spherical
Fourier transform and the formulation of plane-wave sound fields in
the spherical harmonic domain. In turn, the third chapter covers
the theory of spatial sampling, employed when selecting the
positions of microphones to sample sound pressure functions in
space. Subsequent chapters highlight various spherical array
configurations, including the popular rigid-sphere-based
configuration. Beamforming (spatial filtering) in the spherical
harmonics domain, including axis-symmetric beamforming, and the
performance measures of directivity index and white noise gain are
introduced, and a range of optimal beamformers for spherical
arrays, including those that achieve maximum directivity and
maximum robustness are developed, along with the Dolph-Chebyshev
beamformer. The final chapter discusses more advanced beamformers,
such as MVDR (minimum variance distortionless response) and LCMV
(linearly constrained minimum variance) types, which are tailored
to the measured sound field. Mathworks kindly distributes the

Electroacoustic transducers (EAT) are devices, which transform
electric energy to energy of acoustic fluctuations. Principles of
action, design of transducers for work in air and water as well as
for non-destructive control are described in the book. New
technologies of designing EAT, not only expanding designing
possibilities, are described. They also allow to create transducers
with improved characteristics. In particular, methods to increase
target capacity (sound pressure), decrease working (resonant)
frequency of transducers and expand frequencies of projectors and
sound receivers are developed. Methods and control units of
transducers in batch production of transducers are described, too.
This textbook provides a detailed introduction to the use of
software in combination with simple and economical hardware (a
sound level meter with calibrated AC output and a digital recording
system) to obtain sophisticated measurements usually requiring
expensive equipment. It emphasizes the use of free, open source,
and multiplatform software. Many commercial acoustical measurement
systems use software algorithms as an integral component; however
the methods are not disclosed. This book enables the reader to
develop useful algorithms and provides insight into the use of
digital audio editing tools to document features in the signal.
Topics covered include acoustical measurement principles, in-depth
critical study of uncertainty applied to acoustical measurements,
digital signal processing from the basics, and
metrologically-oriented spectral and statistical analysis of
signals. The student will gain a deep understanding of the use of
software for measurement purposes; the ability to implement
software-based measurement systems; familiarity with the hardware
necessary to acquire and store signals; an appreciation for the key
issue of long-term preservation of signals; and a full grasp of the
often neglected issue of uncertainty in acoustical measurements.
Pedagogical features include in-text worked-out examples,
end-of-chapter problems, a glossary of metrology terms, and
extensive appendices covering statistics, proofs, additional
examples, file formats, and underlying theory.
This book provides results of analysis of typical solar events,
statistical analysis, the diagnostics of energetic electrons and
magnetic field, as well as the global behavior of solar flaring
loops such as their contraction and expansion. It pays particular
attention to analyzing solar flare loops with microwave, hard
X-ray, optical and EUV emissions, as well as the theories of their
radiation, and electron acceleration/transport. The results
concerning influence of the pitch-angle anisotropy of non-thermal
electrons on their microwave and hard X-ray emissions, new spectral
behaviors in X-ray and microwave bands, and results related to the
contraction of flaring loops, are widely discussed in the
literature of solar physics. The book is useful for graduate
students and researchers in solar and space physics.

relationship with fundamental biological processes. This book
provides insight on the chemistry, structures, model systems, and
techniques employed for studying membrane properties and processes.
A major focus is on the prominence of membranes in diverse
physiological processes and disease, as well as applications of
membranes and biomimetic membrane systems in varied disciplines.
The book aims to illuminate the significance and beauty of membrane
science, and serve both as an entry point for scholars wishing to
embark on membrane research, as well as scientists already working
in the field.
This book highlights the manufacturing and applications of acoustic
textiles in various industries. It also includes examples from
different industries in which acoustic textiles can be used to
absorb noise and help reduce the impact of noise at the workplace.
Given the importance of noise reduction in the working environment
in several industries, the book offers a valuable guide for
companies, educators and researchers involved with acoustic
materials.
Race to the Moon is a suspenseful thriller about the 30-year clash
between the United States and the Soviet Union to be the first to
put a man on the moon. This true account is heavy with intrigue,
espionage, and controversy. Beginning with a 1961 pledge by
President John F. Kennedy to plant the Stars and Stripes on the
lunar surface by the end of the decade, the story flashes back to
the first days of World War II. At that time, England was tipped
off by a high Nazi official that the Third Reich was developing
revolutionary long-range rockets. This same source clandestinely
provided documents that shocked British scientists: The Germans
were 25 years ahead of England and the United States in rocket
development! And then, in September 1944, 60-foot-long V-2 rockets,
for which there was no defense, began raining down on London,
causing enormous destruction and loss of life. Even while the
fighting was still raging in Germany in the spring of 1945, a
handful of young U.S. Army officers scored a colossal coup: They
connived to steal 100 of the huge V-2s that had been found in an
underground factory. They were dismantled and slipped by train out
of Germany, destination White Sands, New Mexico. Then began a
no-holds-barred search for German rocket scientists in the chaos of
a defeated Third Reich, with the Americans and British on one side
and the Russians on the other. Within weeks of the close of the
war, Wernher von Braun and 126 of his rocket team members were
corraled, shipped to the United States, and began working secretly
on missile development. At the same time, the Soviets literally
kidnapped other German rocket scientists and sent them to Russia to
continue their space work. In the years ahead, Wernher von Braun
and his German rocket team, nearly all of whom became naturalized
citizens of the United States, collaborated with American
scientists to overcome enormous space achievements by the
Soviets--and bungling by Washington politicians--to send Neil
Armstrong scampering about on the moon in 1969.
This book highlights the symmetry properties of acoustic fields and
describes the gauge invariance approach, which can be used to
reveal those properties. Symmetry is the key theoretical framework
of metamaterials, as has been demonstrated by the successful
fabrication of acoustical metamaterials. The book first provides
the necessary theoretical background, which includes the covariant
derivative, the vector potential, and invariance in coordinate
transformation. This is followed by descriptions of global gauge
invariance (isotropy), and of local gauge invariance (anisotropy).
Sections on time reversal symmetry, reflection invariance, and
invariance of finite amplitude waves round out the coverage.

The story of the people who designed, built, launched, landed, and
are now operating the Mars rover "Curiosity"
Award-winning science writer Rod Pyle provides a behind-the-scenes
look into the recent space mission to Mars of "Curiosity"--the
unmanned rover that is now providing researchers with unprecedented
information about the red planet. Pyle follows the team of
dedicated scientists whose job it is to explore new vistas on Mars.
Readers will also join "Curiosity," the most advanced machine ever
sent to another planet, on its journey of discovery. Drawing on his
contacts at NASA and the Jet Propulsion Laboratory, the author
provides stunning insights into how this enthusiastic team of
diverse individuals uses a revolutionary onboard laboratory of
chemistry, geology, and physics instruments to unravel the profound
secrets of the Red Planet.
Readers will meet: Robert Manning, chief engineer for every rover
mission since "Pathfinder"; John Grotzinger, the chief scientist of
the entire mission; Vandi Tompkins, the software designer who keeps
the rover on track; Bobak Ferdowsi, famed "Mohawk Guy" from Mission
Control; Adam Steltzner, the Elvis-like Entry, Descent and Landing
Lead; Al Chen, chief of flight dynamics and the voice of JPL during
"Curiosity"'s treacherous landing; and many others.
And of course, Pyle describes the adventures of the "Curiosity"
rover itself, from landing through the first samples, drilling, and
discovering a habitable past on the planet, to reaching the
ultimate target: Mount Sharp, in the center of Gale Crater.
America is once again at the forefront of a new space age and
"Curiosity" is just the beginning of many exciting new discoveries
to come.
Presents a comprehensive synopsis of the current state of cosmic
rays, their modulation and their effects in the Earth's atmosphere.
Leading scientists in the field assess the current state of our
understanding of the spatial and temporal variations of galactic
and anomalous cosmic rays in the Heliosphere, and their relation to
effects of the Sun. The main objective is to understand the spatial
and temporal variation of galactic and anomalous cosmic rays in the
light of recent observations, theory and modeling by identifying
the key mechanism(s) of cosmic ray modulation and how changes on
the Sun relate to changes in the observed characteristics of cosmic
rays in the Heliosphere; examining the current long-lasting solar
minimum and understand its implications for solar-cycle variations
and long-term variations; and interpreting the long-term variations
of cosmogenic radionuclides in terms of solar variability and
climate change on Earth. This volume is aimed at graduate students
active in the fields of solar physics, space science, and cosmic
ray physics. Originally published in Space Science Reviews journal,
Vol. 176/1-4, 2013.
