The 34 chapters of the 2nd edition of How to Gain Gain give a
detailed insight into a collection (54) of the most common gain
producing, constant current generating possibilities, and
electronic noise creation of triodes for audio pre-amplifier
purposes. These chapters also offer complete sets of formulae to
calculate gain, frequency and phase responses, and signal-to-noise
ratios of certain building blocks built-up with this type of vacuum
valve (tube). In all cases detailed derivations of the gain
formulae are also presented. All what is needed are the data sheet
valve characteristic figures of the triode's mutual conductance,
the gain factor and the internal plate (anode) resistance. To
calculate frequency and phase responses of gain stages the
different data sheet based input and output capacitances have to be
taken into account too. To calculate transfer functions and
signal-to-noise ratios for any kind of triode driven gain stage,
including all its bias setting, frequency, phase, and electronic
noise influencing components, example Mathcad 11 worksheets as an
essential simulation tool for each chapter allow easy follow-up and
application of the respective formulae. Free download of all
worksheets is guaranteed from the editor's web-site.
Wheat is produced on a greater area, grown over a wider geographic
range, and traded internationally as a commodity more than any
other arable crop. Wheat alone provides 20% of the calories and
protein in the global human diet. Understanding the interactions
between wheat production, the environment, and human nutrition is
essential for meeting the demands of food security as we approach
the middle of the 21st century. Wheat: Environment, Food and Health
is written by two leading authorities in the field and offers
insights into critical issues such as the sustainability of wheat
production, the challenges of both mitigating and adapting to
environmental change, and the effects of wheat consumption on human
health. Covering a broad range of topics, the authors: Introduce
the historical development and utilization of the wheat crop.
Describe the factors affecting the quality and acceptability of
wheat for different uses. Discuss the soil characteristics that are
required for, and changed by, wheat production. Examine the water,
temperature, and light requirements of wheat systems. Explore the
methods and sustainability of plant breeding and farmer approaches
to improving crop yields. Describe the development, structure, and
composition of wheat grain. Discuss the contribution and impacts,
both positive and negative, of wheat consumption on human health. -
Discuss how modern technologies and new approaches are addressing
the challenges of maintaining wheat production. Wheat: Environment,
Food and Health is an essential resource for researchers and
academics in disciplines including agriculture, plant biology,
applied biology, botany, food science and nutrition, crop
improvement, food security, environmental sustainability, and human
health.
In Sound Propagation: An Impedance Based Approach, Professor
Yang-Hann Kim introduces acoustics and sound fields by using the
concept of impedance. Kim starts with vibrations and waves,
demonstrating how vibration can be envisaged as a kind of wave,
mathematically and physically. One-dimensional waves are used to
convey the fundamental concepts. Readers can then understand wave
propagation in terms of characteristic and driving point impedance.
The essential measures for acoustic waves, such as dB scale, octave
scale, acoustic pressure, energy, and intensity, are explained.
These measures are all realized by one-dimensional examples, which
provide mathematically simplest but clear enough physical insights.
Kim then moves on to explaining waves on a flat surface of
discontinuity, demonstrating how propagation characteristics of
waves change in space when there is a distributed impedance
mismatch. Next is a chapter on radiation, scattering, and
diffraction, where Kim shows how these topics can be explained in a
unified way, by seeing the changes of waves due to spatially
distributed impedance. Lastly, Kim covers sound in closed space,
which is considered to be a space that is surrounded by spatially
distributed impedance, and introduces two spaces: acoustically
large and small space. The bulk of the book is concerned with
introducing core fundamental concepts, but the appendices are
included as the essentials as well to cover other important topics
to extend learning. * Offers a less mathematically-intensive means
to understand the subject matter * Provides an excellent launching
point for more advanced study or for review of the basics * Based
on classroom tested materials developed over the course of two
decades * Companion site for readers, containing animations and
MATLAB code downloads * Videos and impedance data available from
the author's website * Presentation slides available for instructor
use Sound Propagation is geared towards graduate students and
advanced undergraduates in acoustics, audio engineering, and noise
control engineering. Practicing engineers and researchers in audio
engineering and noise control, or students in engineering and
physics disciplines, who want to gain an understanding of sound and
vibration concepts, will also find the book to be a helpful
resource.
This book focuses on opera house acoustics based on subjective
preference theory; it targets researchers in acoustics and vision
who are working in physics, psychology and brain physiology. This
book helps readers to understand any subjective attributes in
relation to objective parameters based on the powerful and workable
model of the auditory system. It is reconfirmed here that the
well-known Helmholtz theory, which was based on a peripheral model
of the auditory system, may not well describe pitch, timbre and
duration as well as the spatial sensations described in this book,
nor overall responses such as subjective preference of sound fields
and the annoyance of environmental noise.
Documentation of our cultural heritage is experiencing an explosion
of innovation. New tools have appeared in recent decades including
laser scanning, rapid prototyping, high dynamic range spherical and
infrared imagery, drone photography, augmented and virtual reality
and computer rendering in multiple dimensions. These give us
visualisations and data that are at once interesting, intriguing
and yet sometimes deceptive. This text provides an objective and
integrated approach to the subject, bringing together the
techniques of conservation with management, photographic methods,
various modelling techniques and the use of unmanned aerial
systems. This interdisciplinary approach addresses the need for
knowledge about deploying advanced digital technologies and the
materials and methods for the assessment, conservation,
rehabilitation and maintenance of the sustainability of existing
structures and designated historic buildings. Furthermore, this
book actively provides the knowhow to facilitate the creation of
heritage inventories, assessing risk, and addressing the need for
sustainability.In so doing it becomes more feasible to mitigate the
threats from inherent and external causes, not only for the built
heritage but also for moveable objects and intangible heritage that
suffer abandonment and negligence as well as looting and illegal
trafficking. The book is written by a team of international experts
based upon their practical experience and expertise. It therefore
creates a unique book that encapsulates the knowledge of this
discipline required by anyone working in this field.
Roughly defined as any property other than pitch, duration, and
loudness that allows two sounds to be distinguished, timbre is a
foundational aspect of hearing. The remarkable ability of humans to
recognize sound sources and events (e.g., glass breaking, a
friend's voice, a tone from a piano) stems primarily from a
capacity to perceive and process differences in the timbre of
sounds. Timbre raises many important issues in psychology and the
cognitive sciences, musical acoustics, speech processing, medical
engineering, and artificial intelligence. Current research on
timbre perception unfolds along three main fronts: On the one hand,
researchers explore the principal perceptual processes that
orchestrate timbre processing, such as the structure of its
perceptual representation, sound categorization and recognition,
memory for timbre, and its ability to elicit rich semantic
associations, as well as the underlying neural mechanisms. On the
other hand, timbre is studied as part of specific scenarios,
including the perception of the human voice, as a structuring force
in music, as perceived with cochlear implants, and through its role
in affecting sound quality and sound design. Finally, computational
acoustic models are sought through prediction of psychophysical
data, physiologically inspired representations, and audio
analysis-synthesis techniques. Along these three scientific fronts,
significant breakthroughs have been achieved during the last
decade. This volume will be the first book dedicated to a
comprehensive and authoritative presentation of timbre perception
and cognition research and the acoustic modeling of timbre. The
volume will serve as a natural complement to the SHAR volumes on
the basic auditory parameters of Pitch edited by Plack, Oxenham,
Popper, and Fay, and Loudness by Florentine, Popper, and Fay.
Moreover, through the integration of complementary scientific
methods ranging from signal processing to brain imaging, the book
has the potential to leverage new interdisciplinary synergies in
hearing science. For these reasons, the volume will be
exceptionally valuable to various subfields of hearing science,
including cognitive auditory neuroscience, psychoacoustics, music
perception and cognition, but may even exert significant influence
on fields such as musical acoustics, music information retrieval,
and acoustic signal processing. It is expected that the volume will
have broad appeal to psychologists, neuroscientists, and
acousticians involved in research on auditory perception and
cognition. Specifically, this book will have a strong impact on
hearing researchers with interest in timbre and will serve as the
key publication and up-to-date reference on timbre for graduate
students, postdoctoral researchers, as well as established
scholars.

Acoustics deals with the production, control, transmission,
reception, and effects of sound. Owing to acoustics being an
interdisciplinary field, this book is intended to be equally
accessible to readers from a range of backgrounds including
electrical engineering, physics and mechanical engineering.
This book introduces the fundamentals of acoustic wave motion.
It addresses in a clear and systematic way some of the most
difficult parts of acoustics for beginners, such as the widely
different approximations due to the wide frequency range, the
apparently arbitrary choice between the use of analytical solutions
to the wave equation with boundary conditions, and the
fundamentally different energy-based considerations used in noise
control. As a result, it provides readers with a self-contained
source of information on acoustics which can be used for self-study
or as a graduate course text.
Key features: Places an emphasis on detailed derivations based
on the fundamental laws of physics and interpretations of the
resulting formulas.Avoids, where possible, electrical and
mechanical equivalent circuits, so as to make it accessible to
readers with different backgrounds.Introduces duct acoustics, sound
in enclosures, and sound radiation and scattering.Contains a set of
appendices which includes material on signal analysis and
processing as these tools are essential for the modern
acoustician.

Few decorative crafts can claim to be more ancient than stone
carving, with the earliest carved objects being dated well into
prehistory. The greatest monuments to human civilization, from the
temples of ancient Mesopotamia and Egypt to the great cathedrals of
Medieval Europe, are richly ornamented with decorative relief and
sculpture carved in stone. Alan Micklethwaite, a stone carver with
many years' experience in the conservation of historic monuments
and sculpture, introduces the reader to the techniques and
methodology of restoration stone carving, from simple relief to
complex sculpture in the round, set against a sound conservation
philosophy. The book provides a thorough understanding of stone as
a material and describes its use in sculpture and the agents of its
decay, as well as the method by which disfigured carvings can be
forensically reconstructed, resulting in the re-emergence of
beautifully carved historic architectural sculpture. The book is
intended as a detailed introduction to restoration stone carving,
and is aimed at those who are learning to carve stone or have an
interest in pursuing a career in the conservation of stone
sculpture and ancient monuments. While having a depth of detail
which will allow it to serve as a reference manual for the
professional, it will also inspire the beginner and fuel the
interest of those who harbour a desire to pursue traditional
crafts.
