Energy and power are fundamental concepts in electromagnetism and
circuit theory, as well as in optics, signal processing, power
engineering, electrical machines, and power electronics. However,
in crossing the disciplinary borders, we encounter understanding
difficulties due to (1) the many possible mathematical
representations of the same physical objects, and (2) the many
possible physical interpretations of the same mathematical
entities. The monograph proposes a quantum and a relativistic
approach to electromagnetic power theory that is based on recent
advances in physics and mathematics. The book takes a fresh look at
old debates related to the significance of the Poynting theorem and
the interpretation of reactive power. Reformulated in the
mathematical language of geometric algebra, the new expression of
electromagnetic power reflects the laws of conservation of
energy-momentum in fields and circuits. The monograph offers a
mathematically consistent and a physically coherent interpretation
of the power concept and of the mechanism of power transmission at
the subatomic (mesoscopic) level. The monograph proves
(paraphrasing Heaviside) that there is no finality in the
development of a vibrant discipline: power theory.
Algebraic and Combinatorial Computational Biology introduces
students and researchers to a panorama of powerful and current
methods for mathematical problem-solving in modern computational
biology. Presented in a modular format, each topic introduces the
biological foundations of the field, covers specialized
mathematical theory, and concludes by highlighting connections with
ongoing research, particularly open questions. The work addresses
problems from gene regulation, neuroscience, phylogenetics,
molecular networks, assembly and folding of biomolecular
structures, and the use of clustering methods in biology. A number
of these chapters are surveys of new topics that have not been
previously compiled into one unified source. These topics were
selected because they highlight the use of technique from algebra
and combinatorics that are becoming mainstream in the life
sciences.
Maple is a comprehensive symbolic mathematics application which is
well suited for demonstrating physical science topics and solving
associated problems. Because Maple is such a rich application, it
has a somewhat steep learning curve. Most existing texts
concentrate on mathematics; the Maple help facility is too detailed
and lacks physical science examples, many Maple-related websites
are out of date giving readers information on older Maple versions.
This book records the author's journey of discovery; he was
familiar with SMath but not with Maple and set out to learn the
more advanced application. It leads readers through the basic Maple
features with physical science worked examples, giving them a firm
base on which to build if more complex features interest them.
This book uses art photography as a point of departure for learning
about physics, while also using physics as a point of departure for
asking fundamental questions about the nature of photography as an
art. Although not a how-to manual, the topics center around
hands-on applications, sometimes illustrated by photographic
processes that are inexpensive and easily accessible to students
(including a versatile new process developed by the author, and
first described in print in this series). A central theme is the
connection between the physical interaction of light and matter on
the one hand, and the artistry of the photographic processes and
their results on the other. This is the third volume in this
three-part series that uses art photography as a point of departure
for learning about physics, while also using physics as a point of
departure for asking fundamental questions about the nature of
photography as an art. It focuses on the physics and chemistry of
photographic light-sensitive materials, as well as the human
retina. It also considers the fundamental nature of digital
photography and its relationship to the analog photography that
preceded it.
This book on finite element-based computational methods for solving
incompressible viscous fluid flow problems shows readers how to
apply operator splitting techniques to decouple complicated
computational fluid dynamics problems into a sequence of relatively
simpler sub-problems at each time step, such as hemispherical
cavity flow, cavity flow of an Oldroyd-B viscoelastic flow, and
particle interaction in an Oldroyd-B type viscoelastic fluid.
Efficient and robust numerical methods for solving those resulting
simpler sub-problems are introduced and discussed. Interesting
computational results are presented to show the capability of
methodologies addressed in the book.
Quartic anharmonic oscillator with potential V(x)= x(2) + g(2)x4
was the first non-exactly-solvable problem tackled by the
newly-written Schroedinger equation in 1926. Since that time
thousands of articles have been published on the subject, mostly
about the domain of small g(2) (weak coupling regime), although
physics corresponds to g(2) ~ 1, and they were mostly about
energies.This book is focused on studying eigenfunctions as a
primary object for any g(2). Perturbation theory in g(2) for the
logarithm of the wavefunction is matched to the true semiclassical
expansion in powers of : it leads to locally-highly-accurate,
uniform approximation valid for any g(2) [0, ) for eigenfunctions
and even more accurate results for eigenvalues. This method of
matching can be easily extended to the general anharmonic
oscillator as well as to the radial oscillators. Quartic, sextic
and cubic (for radial case) oscillators are considered in detail as
well as quartic double-well potential.
This book demonstrates Microsoft EXCEL-based Fourier transform of
selected physics examples. Spectral density of the auto-regression
process is also described in relation to Fourier transform. Rather
than offering rigorous mathematics, readers will "try and feel"
Fourier transform for themselves through the examples. Readers can
also acquire and analyze their own data following the step-by-step
procedure explained in this book. A hands-on acoustic spectral
analysis can be one of the ideal long-term student projects.
Holographic dualities are at the forefront of contemporary physics
research, peering into the fundamental nature of our universe and
providing best attempt answers to humankind's bold questions about
basic physical phenomena. Yet, the concepts, ideas and mathematical
rigors associated with these dualities have long been reserved for
the specific field researchers and experts. This book shatters this
long held paradigm by bringing several aspects of holography
research into the class room, starting at the college physics level
and moving up from there.
The introduction of cross diffusivity opens many questions in the
theory of reactiondiffusion systems. This book will be the first to
investigate such problems presenting new findings for researchers
interested in studying parabolic and elliptic systems where
classical methods are not applicable. In addition, The
Gagliardo-Nirenberg inequality involving BMO norms is improved and
new techniques are covered that will be of interest. This book also
provides many open problems suitable for interested Ph.D students.
This book highlights new developments in the wide and growing field
of partial differential equations (PDE)-constrained optimization.
Optimization problems where the dynamics evolve according to a
system of PDEs arise in science, engineering, and economic
applications and they can take the form of inverse problems,
optimal control problems or optimal design problems. This book
covers new theoretical, computational as well as implementation
aspects for PDE-constrained optimization problems under
uncertainty, in shape optimization, and in feedback control, and it
illustrates the new developments on representative problems from a
variety of applications.
This book provides a concise introduction to both the special
theory of relativity and the general theory of relativity. The
format is chosen to provide the basis for a single semester course
which can take the students all the way from the foundations of
special relativity to the core results of general relativity: the
Einstein equation and the equations of motion for particles and
light in curved spacetime. To facilitate access to the topics of
special and general relativity for science and engineering students
without prior training in relativity or geometry, the relevant
geometric notions are also introduced and developed from the ground
up. Students in physics, mathematics or engineering with an
interest to learn Einstein's theories of relativity should be able
to use this book already in the second semester of their third
year. The book could also be used as the basis of a graduate level
introduction to relativity for students who did not learn
relativity as part of their undergraduate training.
This book provides a set of theoretical and numerical tools useful
for the study of wave propagation in metamaterials and photonic
crystals. While concentrating on electromagnetic waves, most of the
material can be used for acoustic (or quantum) waves. For each
presented numerical method, numerical code written in MATLAB (R) is
presented. The codes are limited to 2D problems and can be easily
translated in Python or Scilab, and used directly with Octave as
well.
This book contains an extensive illustration of use of finite
difference method in solving the boundary value problem
numerically. A wide class of differential equations has been
numerically solved in this book. Starting with differential
equations of elementary functions like hyperbolic, sine and cosine,
we have solved those of special functions like Hermite, Laguerre
and Legendre. Those of Airy function, of stationary localised
wavepacket, of the quantum mechanical problem of a particle in a 1D
box, and the polar equation of motion under gravitational
interaction have also been solved. Mathematica 6.0 has been used to
solve the system of linear equations that we encountered and to
plot the numerical data. Comparison with known analytic solutions
showed nearly perfect agreement in every case. On reading this
book, readers will become adept in using the method.
Containing an extensive illustration of the use of finite
difference method in solving boundary value problem numerically, a
wide class of differential equations have been numerically solved
in this book.
In the last years there have been great advances in the
applications of topology and differential geometry to problems in
condensed matter physics. Concepts drawn from topology and geometry
have become essential to the understanding of several phenomena in
the area. Physicists have been creative in producing models for
actual physical phenomena which realize mathematically exotic
concepts and new phases have been discovered in condensed matter in
which topology plays a leading role. An important classification
paradigm is the concept of topological order, where the state
characterizing a system does not break any symmetry, but it defines
a topological phase in the sense that certain fundamental
properties change only when the system passes through a quantum
phase transition. The main purpose of this book is to provide a
brief, self-contained introduction to some mathematical ideas and
methods from differential geometry and topology, and to show a few
applications in condensed matter. It conveys to physicists the
basis for many mathematical concepts, avoiding the detailed
formality of most textbooks.
Uncertainties in GPS Positioning: A Mathematical Discourse
describes the calculations performed by a GPS receiver and the
problems associated with ensuring that the derived location is a
close match to the actual location. Inaccuracies in calculating a
location can have serious repercussions, so this book is a timely
source for information on this rapidly evolving technology.
For a physicist, "noise" is not just about sounds, but refers to
any random physical process that blurs measurements, and in so
doing stands in the way of scientific knowledge. This book deals
with the most common types of noise, their properties, and some of
their unexpected virtues. The text explains the most useful
mathematical concepts related to noise. Finally, the book aims at
making this subject more widely known and to stimulate the interest
for its study in young physicists.
