This book discusses in detail the special theory of relativity
without including all the instruments of theoretical physics,
enabling readers who are not budding theoretical physicists to
develop competence in the field. An arbitrary but fixed inertial
system is chosen, where the known velocity of light is measured.
With respect to this system a moving clock loses time and a moving
length contracts. The book then presents a definition of
simultaneity for the other inertial frames without using the
velocity of light. To do so it employs the known reciprocity
principle, which in this context serves to provide a definition of
simultaneity in the other inertial frames. As a consequence, the
Lorentz transformation is deduced and the universal constancy of
light is established. With the help of a lattice model of the
special theory of relativity the book provides a deeper
understanding of the relativistic effects. Further, it discusses
the key STR experiments and formulates and solves 54 problems in
detail.
This volume gathers selected contributions from the participants of
the Banff International Research Station (BIRS) workshop Coupled
Mathematical Models for Physical and Biological Nanoscale Systems
and their Applications, who explore various aspects of the
analysis, modeling and applications of nanoscale systems, with a
particular focus on low dimensional nanostructures and coupled
mathematical models for their description. Due to the vastness,
novelty and complexity of the interfaces between mathematical
modeling and nanoscience and nanotechnology, many important areas
in these disciplines remain largely unexplored. In their efforts to
move forward, multidisciplinary research communities have come to a
clear understanding that, along with experimental techniques,
mathematical modeling and analysis have become crucial to the
study, development and application of systems at the nanoscale. The
conference, held at BIRS in autumn 2016, brought together experts
from three different communities working in fields where coupled
mathematical models for nanoscale and biosystems are especially
relevant: mathematicians, physicists (both theorists and
experimentalists), and computational scientists, including those
dealing with biological nanostructures. Its objectives: summarize
the state-of-the-art; identify and prioritize critical problems of
major importance that require solutions; analyze existing
methodologies; and explore promising approaches to addressing the
challenges identified. The contributions offer up-to-date
introductions to a range of topics in nano and biosystems, identify
important challenges, assess current methodologies and explore
promising approaches. As such, this book will benefit researchers
in applied mathematics, as well as physicists and biologists
interested in coupled mathematical models and their analysis for
physical and biological nanoscale systems that concern applications
in biotechnology and medicine, quantum information processing and
optoelectronics.
This book aims to bring together researchers and practitioners
working across domains and research disciplines to measure, model,
and visualize complex networks. It collects the works presented at
the 9th International Conference on Complex Networks (CompleNet) in
Boston, MA, March, 2018. With roots in physical, information and
social science, the study of complex networks provides a formal set
of mathematical methods, computational tools and theories to
describe, prescribe and predict dynamics and behaviors of complex
systems. Despite their diversity, whether the systems are made up
of physical, technological, informational, or social networks, they
share many common organizing principles and thus can be studied
with similar approaches. This book provides a view of the
state-of-the-art in this dynamic field and covers topics such as
group decision-making, brain and cellular connectivity, network
controllability and resiliency, online activism, recommendation
systems, and cyber security.
The book provides both the theoretical and the applied background
needed to predict magnetic fields. The theoretical presentation is
reinforced with over 60 solved examples of practical engineering
applications such as the design of magnetic components like
solenoids, which are electromagnetic coils that are moved by
electric currents and activate other devices such as circuit
breakers. Other design applications would be for permanent magnet
structures such as bearings and couplings, which are hardware
mechanisms used to fashion a temporary connection between two
wires.
This book is written for use as a text or reference by researchers,
engineers, professors, and students engaged in the research,
development, study, and manufacture of permanent magnets and
electromechanical devices. It can serve as a primary or
supplemental text for upper level courses in electrical engineering
on electromagnetic theory, electronic and magnetic materials, and
electromagnetic engineering.
This is the third volume in a three-part series that uses art
photography as a point of departure for learning about physics,
while also using physics to ask fundamental questions about the
nature of photography as an art.
Cold atmospheric plasma (CAP) emerges as a possible new modality
for cancer treatment. This book provides a comprehensive
introduction into the fundamentals of the CAP and plasma devices
used in plasma medicine. An analysis of the mechanisms of plasma
interaction with cancer and normal cells, including a description
of possible mechanisms of plasma selectivity, is included. Recent
advances in the field, the primary challenges and future directions
are also presented.
In recent years, scientists and researchers have been continually
searching for efficient and effective ways to harness solar energy
for heat and power production. The development of solar
technologies and thermal systems are a prevalent area of study, as
they represent a vital step in fully optimizing the potential of
solar energy. Unfortunately, research is still lacking on the
development and application of these solar thermal systems.
Modeling and Optimization of Solar Thermal Systems: Emerging
Research and Opportunities provides emerging research exploring the
theoretical and practical aspects of optimizing the performance of
solar thermal technologies using multicriteria decision-making
techniques. Featuring coverage on a broad range of topics such as
parabolic trough collectors, hybrid solar energy, and thermal
technology, this book is ideally designed for practitioners,
engineers, academicians, researchers, students, industry
professionals, and educators seeking current research on modern
modeling methods of solar thermal systems.
Waste to Energy deals with the very topical subject of converting
the calorific content of waste material into useful forms of
energy. It complements and, to a certain degree, overlaps with its
companion volume, "Biomass to Biofuels", since a significant
proportion of biomass converted to energy nowadays originates from
various types of waste. The material in the first, more substantial
part of the volume has been arranged according to the type of
process for energy conversion. Biochemical processes are described
in six articles. These relate to the production of methane by
anaerobic digestion; reactor conversion efficiencies;
investigations on ethanol production from biodegradable municipal
solid waste through hydrolysis and fermentation; hydrogen
production from glucose through a hybrid anaerobic and
photosynthetic process; biodiesel production from used cooking oil
through base-catalyzed transesterification. Conversions by
thermochemical processes are discussed in the subsequent eleven
articles of the volume.These cover combustion, the direct use of
heat energy; using the heat produced in thermal power stations for
steam and, ultimately, electricity generation; municipal solid
waste and refuse-derived fuel. In another article, computational
fluid dynamics modelling is applied to assess the influence of
process parameters and to perform optimization studies. A group of
articles deal with more complex thermochemical processes involving
combustion combined with pyrolysis and gasification. Two articles
focus on biofuels as feed for fuel cells. In the last six articles,
the emphasis is on management and policy rather than technical
issues.
This textbook provides a sound foundation in physical optics by
covering key concepts in a rigorous but accessible manner.
Propagation of electromagnetic waves is examined from multiple
perspectives, with explanation of which viewpoints and methods are
best suited to different situations. After an introduction to the
theory of electromagnetism, reflection, refraction, and dispersion,
topics such as geometrical optics, interference, diffraction,
coherence, laser beams, polarization, crystallography, and
anisotropy are closely examined. Optical elements, including
lenses, mirrors, prisms, classical and Fabry-Perot interferometers,
resonant cavities, multilayer dielectric structures, interference
and spatial filters, diffraction gratings, polarizers, and
birefringent plates, are treated in depth. The coverage also
encompasses such seldom-covered topics as modeling of general
astigmatism via 4x4 matrices, FFT-based numerical methods, and
bianisotropy, with a relativistic treatment of optical activity and
the Faraday and Fresnel-Fizeau effects. Finally, the history of
optics is discussed.
This monograph provides a concise overview of the main theoretical
and numerical tools to solve homogenization problems in solids with
finite elements. Starting from simple cases (linear thermal case)
the problems are progressively complexified to finish with
nonlinear problems. The book is not an overview of current research
in that field, but a course book, and summarizes established
knowledge in this area such that students or researchers who would
like to start working on this subject will acquire the basics
without any preliminary knowledge about homogenization. More
specifically, the book is written with the objective of practical
implementation of the methodologies in simple programs such as
Matlab. The presentation is kept at a level where no deep
mathematics are required.
Advances in Imaging and Electron Physics, Volume 206, merges two
long-running serials, Advances in Electronics and Electron Physics
and Advances in Optical and Electron Microscopy. The series
features extended articles on the physics of electron devices
(especially semiconductor devices), particle optics at high and low
energies, microlithography, image science, digital image
processing, electromagnetic wave propagation, electron microscopy,
and the computing methods used in all these domains.
Integrated Nano-Biomechanics provides an integrated look into the
rapidly evolving field of nanobiomechanics. The book demystifies
the processes in living organisms at the micro- and nano-scale
through mechanics, using theoretical, computational and
experimental means. The book develops the concept of integrating
different technologies along the hierarchical structure of
biological systems and clarifies biomechanical interactions among
different levels for the analysis of multi-scale pathophysiological
phenomena. With a focus on nano-scale processes and biomedical
applications, it is shown how knowledge obtained can be utilized in
a range of areas, including diagnosis and treatment of various
human diseases and alternative energy production. This book is
based on collaboration of researchers from a unique combination of
fields, including biomechanics, computational mechanics, GPU
application, electron microscopy, biology of motile
micro-organisms, entomological mechanics and clinical medicine. The
book will be of great interest to scientists and researchers
involved in disciplines, such as micro- and nano-engineering,
bionanotechnology, biomedical engineering, micro- and nano-scale
fluid-mechanics (such as in MEMS devices), nanomedicine and
microbiology, as well as industries such as optical devices,
computer simulation, plant based energy sources and clinical
diagnosis of the gastric diseases.
This book is a self-contained account of the method based on
Carleman estimates for inverse problems of determining spatially
varying functions of differential equations of the hyperbolic type
by non-overdetermining data of solutions. The formulation is
different from that of Dirichlet-to-Neumann maps and can often
prove the global uniqueness and Lipschitz stability even with a
single measurement. These types of inverse problems include
coefficient inverse problems of determining physical parameters in
inhomogeneous media that appear in many applications related to
electromagnetism, elasticity, and related phenomena. Although the
methodology was created in 1981 by Bukhgeim and Klibanov, its
comprehensive development has been accomplished only recently. In
spite of the wide applicability of the method, there are few
monographs focusing on combined accounts of Carleman estimates and
applications to inverse problems. The aim in this book is to fill
that gap. The basic tool is Carleman estimates, the theory of which
has been established within a very general framework, so that the
method using Carleman estimates for inverse problems is
misunderstood as being very difficult. The main purpose of the book
is to provide an accessible approach to the methodology. To
accomplish that goal, the authors include a direct derivation of
Carleman estimates, the derivation being based essentially on
elementary calculus working flexibly for various equations. Because
the inverse problem depends heavily on respective equations, too
general and abstract an approach may not be balanced. Thus a direct
and concrete means was chosen not only because it is friendly to
readers but also is much more relevant. By practical necessity,
there is surely a wide range of inverse problems and the method
delineated here can solve them. The intention is for readers to
learn that method and then apply it to solving new inverse
problems.
