How gunpowder technology exploded heroes, heroics, and war stories
from 1400 to 1700, and how German writers tried to glue them back
together Guns have been linked with masculinity since their
earliest days on European battlefields, and surviving treatises on
gunpowder from the early fifteenth century describe in detail the
kinds of strong, sober, and God-fearing men who could be trusted to
use this new weapon. As the destructive capacity and military
tactical value of gunpowder became more evident to European peoples
over time, writers--especially German ones--expressed increasing
anxiety aboutthe disruptive potential that gunpowder weapons held
for warrior masculinity, martial ethics, and the aesthetic
traditions of war stories. Focused on early modern German texts of
all kinds, including military manuals,poems, theological treatises,
novels, and broadsheets, Gunpowder, Masculinity, and Warfare in
German Texts, 1400-1700 traces the cultural and literary history of
gunpowder in German-speaking lands from the Hussite Wars into the
literary aftermath of the Thirty Years War. Taking a long view of
this textual and material history, author Patrick Brugh reveals
that early conversations about firearms resonate with those today,
including debates on such topics as questions of masculine ethos
and gun violence, the rights to self-defense and to bear arms, and
the way new technologies change how we tell stories. PATRICK BRUGH
is an affiliate assistant professor of Genderand Sexuality Studies
at Loyola University Maryland and an administrator at Johns Hopkins
University.
This book addresses the nature of sound, focusing on the
characteristics of sound waves in the context of time structures.
This time domain approach provides an informative and intuitively
understandable description of various acoustic topics such as sound
waves travelling in an acoustic tube or in other media where
spectral or modal analysis can be intensively performed. Starting
from the introductory topic of sinusoidal waves, it discusses the
formal relationship between the time and frequency domains,
summarizing the fundamental notions of Fourier or z-transformations
and linear systems theory, along with interesting examples from
acoustical research. The books novel approach is of interest to
research engineers and scientists In particular, the expressions
concerning waveforms including the impulse responses are important
for audio engineers who are familiar with digital signal analysis.
Every chapter includes simple exercises designed to be solved
without the need for a computer. Thus they help reconfirm the
fundamental ideas and notions present in every chapter. The book is
self-contained and concise, and requires only basic knowledge of
acoustics and signal processing, making it valuable as a textbook
for graduate and undergraduate university courses.
This monograph traces the development of our understanding of how
and where energetic particles are accelerated in the heliosphere
and how they may reach the Earth. Detailed data sets are presented
which address these topics. The bulk of the observations are from
spacecraft in or near the ecliptic plane. It is timely to present
this subject now that Voyager-1 has entered the true interstellar
medium. Since it seems unlikely that there will be a follow-on to
the Voyager programme any time soon, the data we already have
regarding the outer heliosphere are not going to be enhanced for at
least 40 years.
How the scientific community overlooked, ignored, and denied the
catastrophic fallout of decades of nuclear testing in the American
West In December of 1950, President Harry Truman gave authorization
for the Atomic Energy Commission to conduct weapons tests and
experiments on a section of a Nevada gunnery range. Over the next
eleven years, more than a hundred detonations were conducted at the
Nevada Test Site, and radioactive debris dispersed across the
communities just downwind and through much of the country. In this
important work, James C. Rice tells the hidden story of nuclear
weapons testing and the negligence of the US government in
protecting public health. Downwind of the Atomic State focuses on
the key decisions and events shaping the Commission's mismanagement
of radiological contamination in the region, specifically on how
the risks of fallout were defined and redefined, or, importantly,
not defined at all, owing to organizational mistakes and the
impetus to keep atomic testing going at all costs. Rice shows that
although Atomic Energy Commission officials understood open-air
detonations injected radioactive debris into the atmosphere, they
did not understand, or seem to care, that the radioactivity would
irrevocably contaminate these communities. The history of the
atomic Southwest should be a wake-up call to everyone living in a
world replete with large, complex organizations managing risky
technological systems. The legacy of open-air detonations in Nevada
pushes us to ask about the kinds of risks we are unwittingly living
under today. What risks are we being exposed to by large
organizations under the guise of security and science?
Rather than examining only the civil or military side of the US
space program, as have many books in the past, "Space, the Dormant
Frontier" takes a unique look at the space program as a whole. Part
of the book's treatise is that the two communities must stop
ignoring each other if the US space program is to move forward
beyond being a science project, jobs program, or political
football. How the program got into its current, semi-desperate
state is also examined, as history has given space a legacy once
glorious, now an albatross. The authors include information and
analysis on the military and civil space programs, challenge the
perspective of the Washington Beltway analyst with vested interests
in the status quo, and make policy recommendations based on
realism, rather than idealism.
This multi-contributed volume provides a practical,
applications-focused introduction to nonlinear acoustical
techniques for nondestructive evaluation. Compared to linear
techniques, nonlinear acoustical/ultrasonic techniques are much
more sensitive to micro-cracks and other types of small distributed
damages. Most materials and structures exhibit nonlinear behavior
due to the formation of dislocation and micro-cracks from fatigue
or other types of repetitive loadings well before detectable
macro-cracks are formed. Nondestructive evaluation (NDE) tools that
have been developed based on nonlinear acoustical techniques are
capable of providing early warnings about the possibility of
structural failure before detectable macro-cracks are formed. This
book presents the full range of nonlinear acoustical techniques
used today for NDE. The expert chapters cover both theoretical and
experimental aspects, but always with an eye towards applications.
Unlike other titles currently available, which treat nonlinearity
as a physics problem and focus on different analytical derivations,
the present volume emphasizes NDE applications over detailed
analytical derivations. The introductory chapter presents the
fundamentals in a manner accessible to anyone with an undergraduate
degree in Engineering or Physics and equips the reader with all of
the necessary background to understand the remaining chapters. This
self-contained volume will be a valuable reference to graduate
students through practising researchers in Engineering, Materials
Science, and Physics. Represents the first book on nonlinear
acoustical techniques for NDE applications Emphasizes applications
of nonlinear acoustical techniques Presents the fundamental physics
and mathematics behind nonlinear acoustical phenomenon in a simple,
easily understood manner Covers a variety of popular NDE techniques
based on nonlinear acoustics in a single volume

This book reports on an outstanding thesis that has significantly
advanced the state-of-the-art in the automated analysis and
classification of speech and music. It defines several standard
acoustic parameter sets and describes their implementation in a
novel, open-source, audio analysis framework called openSMILE,
which has been accepted and intensively used worldwide. The book
offers extensive descriptions of key methods for the automatic
classification of speech and music signals in real-life conditions
and reports on the evaluation of the framework developed and the
acoustic parameter sets that were selected. It is not only intended
as a manual for openSMILE users, but also and primarily as a guide
and source of inspiration for students and scientists involved in
the design of speech and music analysis methods that can robustly
handle real-life conditions.
This book offers an essential introduction to the notions of sound
wave topology, duality, coherence and wave-mixing, which constitute
the emerging new science of sound. It includes general principles
and specific examples that illuminate new non-conventional forms of
sound (sound topology), unconventional quantum-like behavior of
phonons (duality), radical linear and nonlinear phenomena
associated with loss and its control (coherence), and exquisite
effects that emerge from the interaction of sound with other
physical and biological waves (wave mixing). The book provides the
reader with the foundations needed to master these complex notions
through simple yet meaningful examples. General principles for
unraveling and describing the topology of acoustic wave functions
in the space of their Eigen values are presented. These principles
are then applied to uncover intrinsic and extrinsic approaches to
achieving non-conventional topologies by breaking the time reversal
symmetry of acoustic waves. Symmetry breaking can impart
topological immunity to wave degradation from imperfection
scattering and catalyze controlled coherence. In the intrinsic case
and the phonon representation of acoustic waves, the
self-interaction/interference of a wave through its supporting
medium exposes the notion of duality in the quantum statistics
(i.e. boson vs. fermion characterized by the symmetry of multiple
particle states) and how the quantum analogue behaviors of sound
can be exploited in the form of novel sound-based information
transfer and processing devices. By considering media that mix
different types of waves, the book addresses the interaction of
sound with other physical and biological waves but also brings to
light examples of extrinsic processes that can lead to symmetry
breaking. The coherent conversion of sound into other types of
waves as well as the sound-induced non-conventional topology of
elastic, electronic, spin and biological waves are presented in the
case of media exhibiting elasto-electronic, photo-elastic,
magneto-elastic effects and biological mechano-transduction.

experiments, observations, calculations, and analytical data from
five astro-sciences, astronomy, astrobiology, astrogeology,
astrophysics, and cosmochemistry. Beginning with the origin of
elements, and moving on to cover the formation of the early Solar
System, the giant impact model of the Earth and Moon, the oldest
records of life, and the possibility of life on other planets in
the Solar System, this interdisciplinary reference provides a
complex understanding of the planets and the formation of life.
Synthesizing concepts from all branches of astro-sciences into one,
the book is a valuable reference for researchers in astrogeology,
astrophysics, cosmochemistry, astrobiology, astronomy, and other
space science fields, helping users better understand the
intersection of these sciences.

weapons can be intercepted and electronically jammed. It offers a
thorough, up-to-date survey of sophisticated weapon and electronic
warfare (EW) systems, and covers all the latest technological
advances in this rapidly-changing area. Brand new material includes
deep explanations of cutting-edge techniques, as well as an
introduction to information operations and information warfare. The
book explores a broad spectrum of defence equipment. It explains
how these systems operate, the advantages and drawbacks of each
system, and the theories on which these systems are based.
The thesis presents a tool to create rubble pile asteroid simulants
for use in numerical impact experiments, and provides evidence that
the asteroid disruption threshold and the resultant fragment size
distribution are sensitive to the distribution of internal voids.
This thesis represents an important step towards a deeper
understanding of fragmentation processes in the asteroid belt, and
provides a tool to infer the interior structure of rubble pile
asteroids. Most small asteroids are 'rubble piles' - re-accumulated
fragments of debris from earlier disruptive collisions. The study
of fragmentation processes for rubble pile asteroids plays an
essential part in understanding their collisional evolution. An
important unanswered question is "what is the distribution of void
space inside rubble pile asteroids?" As a result from this thesis,
numerical impact experiments can now be used to link surface
features to the internal structure and therefore help to answer
this question. Applying this model to asteroid Steins, which was
imaged from close range by the Rosetta spacecraft, a large
hill-like structure is shown to be most likely primordial, while a
catena of pits can be interpreted as evidence for the existence of
fracturing of pre-existing internal voids.
This book provides an overview of paste tailings disposal at mine
sites. It deals comprehensively with the characterization of
sulphide-rich tailings, geotechnical and microstructural behaviour,
surface tailings disposal applications, underground paste
backfilling, and case studies. The authors place emphasis on the
characterization, monitoring, disposal and treatment, as well as
environmental considerations of problematic sulphidic tailings. The
framework is supported by worldwide case studies.
This thesis describes the studies on the solar interior where
turbulent thermal convection plays an important role. The author
solved, for the first time, one of the long-standing issues in
solar physics, i.e., the maintenance mechanism of the solar
differential rotation in the near-surface shear layer. The author
attacked this problem with a newly developed approach, the reduced
speed of sound technique, which enabled him to investigate the
surface and deep solar layers in a self-consistent manner. This
technique also made it possible to achieve an unprecedented
performance in the solar convection simulations for the usage of
the massively parallel supercomputers such as the RIKEN K system.
It was found that the turbulence and the mean flows such as the
differential rotation and the meridional circulation mutually
interact with each other to maintain the flow structures in the
Sun. Recent observations by helioseismology support the author's
proposed theoretical mechanism. The book also addresses the
generation of the magnetic field in such turbulent convective
motions, which is an important step forward for solar cyclic dynamo
research.
