The aim of the book is to present, in a novel and unified fashion,
the elements of Mechanics in Material Space or Configurational
Mechanics, with applications to fracture and defect mechanics. This
mechanics, in contrast to Newtonian mechanics in physical space, is
concerned with defects such as cracks and dislocations, which are
embedded in the material and might move in it. The level is kept
accessible to any engineer, scientist or graduate student
possessing some knowledge of calculus and partial differential
equations, and working in the various areas where rational use of
materials is essential.
The book reports an extended version of the lectures given by distinguished scholars at the workshop "Fault diagnosis and fault tolerance for dynamic systems" held in conjunction with the 2002 IEEE International Symposium on Intelligent Control in Vancouver, Canada, from 27-30 October 2002. The book collects some of the most recent results in fault diagnosis and fault tolerant systems with particular emphasis on mechatronic systems. Each chapter focuses on either theoretical aspects or applications to different fields of interest in mechatronics such as industrial robotics, underwater vehicles, hydraulic systems, and flight control.
The book presents a synopsis of the main results achieved during
the 3 year EU-project "Advanced Inflight Measurement Techniques
(AIM)" which applied advanced image based measurement techniques to
industrial flight testing. The book is intended to be not only an
overview on the AIM activities but also a guide on the application
of advanced optical measurement techniques for future flight
testing. Furthermore it is a useful guide for engineers in the
field of experimental methods and flight testing who face the
challenge of a future requirement for the development of highly
accurate non-intrusive in-flight measurement techniques.
This book is an introduction to the dynamics of reaction-diffusion
systems, with a focus on fronts and stationary spatial patterns.
Emphasis is on systems that are non-standard in the sense that
either the transport is not simply classical diffusion (Brownian
motion) or the system is not homogeneous. A important feature is
the derivation of the basic phenomenological equations from the
mesoscopic system properties. Topics addressed include transport
with inertia, described by persistent random walks and hyperbolic
reaction-transport equations and transport by anomalous diffusion,
in particular subdiffusion, where the mean square displacement
grows sublinearly with time. In particular reaction-diffusion
systems are studied where the medium is in turn either spatially
inhomogeneous, compositionally heterogeneous or spatially discrete.
Applications span a vast range of interdisciplinary fields and the
systems considered can be as different as human or animal groups
migrating under external influences, population ecology and
evolution, complex chemical reactions, or networks of biological
cells. Several chapters treat these applications in detail.
This revised second edition of a popular handbook for engineers describes the important relationship between high-energy radiation environments, electronic device physics and materials. It is a straightforward account of the problems which arise when high-energy radiation bombards matter and of engineering methods for solving those problems. Radiation effects are a problem encountered in the use of highly engineered materials such as semiconductors, optics and polymers. The finely-tuned properties of these materials may change drastically when exposed to a radiation environment such as a bean of X-rays or electrons, the space environment or the 'hadrons' in CERN's new collider. All of these environments and several more are described. The impact of these environments on microelectronics in computing, data processing and communication is the core of this book (highlighted in chapters on MOS and optical devices). While unashamedly oriented to the engineer-designer and manager, with descriptions in a highly readable form, there is no compromise in physical accuracy when describing high-energy radiation and the effects it produces, such as electronic failure, colour centres and the decay of strength. A great breadth of technical data, needed to make predictions on the spot, is presented, with literature references needed for further research and also a compendium of websites which have been tested and used by authors.
One of the major challenges in current chemistry is to ?nd
molecules able to move charges rapidly and ef?ciently from, for
example, one terminus to another one under the control of an
external electrical, electrochemical or photochemical stimulus.
Nature has provided impressive examples of how these goals are
achieved. The photosynthetic reaction center protein, for instance,
rapidly moves electrons with near unity quantum ef?ciency across a
lipid bilayer membrane using several redox cofactors, and thus,
serves as a model for developing biomimetic analogues for
applications in ?elds such as photovoltaic devices, molecular
electronics and photonic materials. In this context, p-conjugated
oligomeric molecular assemblies are of particular interest because
they provide ef?cient electronic couplings between electroactive
units - donor and acceptor termini - and display wire-like
behavior. In order to make a molecule able to behave as an ideal
molecular wire different requirements need to be ful?lled: i)
matching between the donor (acceptor) and bridge energy levels, ii)
a good electronic coupling between the electron donor and acceptor
units via the bridge orbitals, and iii) a small attenuation factor.
Among the many different p-conjugated oligomers,
oligo(p-phenylenevin- enes) (oPPV), have emerged as a particularly
promising model system that helps to comprehend/rationalize the
basic features of polymeric poly(p-phenyle- vinylenes) and also as
a versatile building block for novel materials with che- cally
tailored properties.
The importance of solid base catalysts has come to be recognized
for their environmentally benign qualities, and much significant
progress has been made over the past two decades in catalytic
materials and solid base-catalyzed reactions. The book is focused
on the solid base. Because of the advantages over liquid bases, the
use of solid base catalysts in organic synthesis is expanding.
Solid bases are easier to dispose than liquid bases, separation and
recovery of products, catalysts and solvents are less difficult,
and they are non-corrosive. Furthermore, base-catalyzed reactions
can be performed without using solvents and even in the gas phase,
opening up more possibilities for discovering novel reaction
systems. Using numerous examples, the present volume describes the
remarkable role solid base catalysis can play, given the ever
increasing worldwide importance of "green" chemistry. The reader
will obtain an overall view of solid base catalysis and gain
insight into the versatility of the reactions to which solid base
catalysts can be utilized. The concept and significance of solid
base catalysis are discussed, followed by descriptions of various
methods for the characterization of solid bases, including
spectroscopic methods and test reactions. The preparation and
properties of base materials are presented in detail, with the two
final chapters devoted to surveying the variety of reactions
catalyzed by solid bases.
This book systematizes data on the heterophase states and their
evolution in perovskite-type ferroelectric solid solutions. It also
provides a general interpretation of heterophase and domain
structures on changing temperature, composition or electric field,
as well as the complete analysis of interconnections domain
structures, unit-cell parameters changes, heterophase structures
and stress relief. The description of numerous examples of
heterophase states in lead-free ferroelectric solid solutions is
also included. Domain state-interface diagrams contribute to the
interpretation of heterophase states in perovskite-type
ferroelectric solid solutions and describe the stress relief in the
presence of polydomain phases, the behavior of unit-cell parameters
of coexisting phases, the effect of external electric field etc.
This 2nd edition generalizes the results on the heterophase
ferroelectric solid solutions and the stress relief and presents
new results on heterophase/domain structures and phase contents in
lead-free ferroelectric solid solutions.
Physical models of gas discharge processes in gas flows and
numerical simulation methods, which are used for numerical
simulation of these phenomena are considered in the book.
Significant attention is given to a solution of two-dimensional
problems of physical mechanics of electric arc, radio-frequency,
micro-wave, and optical discharges, as well as to investigation of
electrodynamic structure of direct current glow discharges.
Problems of modern computational magnetohydrodynamics (MHD) are
considered also. Prospects of the different kinds of discharges use
in aerospace applications are discussed. This book is intended for
scientists and engineers concerned with physical gas dynamics,
physics of the low-temperature plasma and gas discharges, and also
for students and post-graduate students of physical and technical
specialties of universities.
This monograph describes plasma physics for magnetic confinement of
high temperature plasmas in nonaxisymmetric toroidal magnetic
fields or stellarators. The techniques are aimed at controlling
nuclear fusion for continuous energy production. While the focus is
on the nonaxisymmetric toroidal field, or heliotron, developed at
Kyoto University, the physics applies equally to other stellarators
and axisymmetric tokamaks. The author covers all aspects of
magnetic confinement, formation of magnetic surfaces,
magnetohydrodynamic equilibrium and stability, single charged
particle confinement, neoclassical transport and plasma heating. He
also reviews recent experiments and the prospects for the next
generation of devices.
Wind Turbine Airfoils and Blades introduces new ideas in the design
of wind turbine airfoils and blades based on functional integral
theory and the finite element method, accompanied by results from
wind tunnel testing. The authors also discuss the optimization of
wind turbine blades as well as results from aerodynamic analysis.
This book is suitable for researchers and engineers in aeronautics
and can be used as a textbook for graduate students.
This volume represents a collection of authoritative reviews by
internationally recognized experts in the field of middle infrared
(mid-IR) coherent sources and their applications. The compilation
describes the fundamental principles and state-of-the-art of
practical solid-state sources in the mid-IR regions of the spectrum
covering the 2-50 m range. Coherent mid-IR sources also offer
important technologies for atmospheric chemistry, free-space
communication, imaging, rapid detection of explosives, chemical and
biological agents, narcotics, as well as for applications in air-
and sea-born security. In comparison to the previous volume on this
subject in 2003, which focused mainly on the design and development
of mid-IR sources, the emphasis in the present volume is shifted
towards applications. The instructive nature of the book makes it
an excellent text for practicing engineers, physicists and graduate
students.
This book provides an interdisciplinary presentation of the current knowledge of pattern formation in complex system, with sufficiently many details, tools, and concrete examples to be useful for the graduate student or scientist entering this area of research.
This book gives an overview of recent advances in the fracture mechanics of polymers (experimental and alternative methods), morphology property correlations (homopolymers, copolymers, blends), hybrid methods for polymer testing and polymer diagnostics, and biocompatible materials and medical prostheses, as well as application examples and limits. The investigation of deformation and fracture behaviour using the experimental methods of fracture mechanics has been the subject of intense research during the last decade. In a systematic manner, each chapter of this book gives a review of the particular aspects. This book will be of great value to scientists, engineers and graduates in polymer materials science.
Light emitting diodes (LEDs) are already used in traffic signals,
signage lighting, and automotive applications. However, its
ultimate goal is to replace traditional illumination through LED
lamps since LED lighting significantly reduces energy consumption
and cuts down on carbon-dioxide emission. Despite dramatic advances
in LED technologies (e.g., growth, doping and processing
technologies), however, there remain critical issues for further
improvements yet to be achieved for the realization of solid-state
lighting. This book aims to provide the readers with some
contemporary LED issues, which have not been comprehensively
discussed in the published books and, on which the performance of
LEDs is seriously dependent. For example, most importantly, there
must be a breakthrough in the growth of high-quality nitride
semiconductor epitaxial layers with a low density of dislocations,
in particular, in the growth of Al-rich and and In-rich GaN-based
semiconductors. The materials quality is directly dependent on the
substrates used, such as sapphire, Si, etc. In addition, efficiency
droop, growth on different orientations and polarization are also
important. Chip processing and packaging technologies are key
issues. This book presents a comprehensive review of contemporary
LED issues. Given the interest and importance of future research in
nitride semiconducting materials and solid state lighting
applications, the contents are very timely. The book is composed of
chapters written by leading researchers in III-nitride
semiconducting materials and device technology. This book will be
of interest to scientists and engineers working on LEDs for
lighting applications. Postgraduate researchers working on LEDs
will also benefit from the issues this book provides.
This book examines the intersection of Organizational Behavior
Management (OBM) and Industrial and Organizational Psychology (I/O
Psychology). It argues that, whilst OBM and I/O Psychology have
developed simultaneously, they have done so with minimal
integration. I/O Psychology, a somewhat older field, has evolved to
become widely accepted, both influencing management and social
sciences and being affected by them. It can be viewed as a
research-oriented subject that is closely aligned with human
resources functions. With regards to the intersection of I/O
Psychology with OBM, some practices are more closely related than
others; and of those that are related, some are relatively
consistent with OBM practices, while others are very inconsistent.
Most I/O Psychology interventions focus on many people
simultaneously, seeking to ensure that one intervention affects
multiple employees as a cost-efficient way to improve
organizations, while OBM is usually better than I/O Psychology at
improving the behaviors of individuals and smaller groups or
workers. This book provides a framework for understanding
differences and similarities between I/O Psychology and OBM, and as
such is an innovative compendium for students, scholars, applied
psychologists, and human resource specialists. It was originally
published as a special issue of the Journal of Organizational
Behavior Management.
In the last decade, optically functionalized materials have
developed rapidly, from bulk matters to structured forms. Now we
have a rich variety of attractive advanced materials. They are
applied to optical and electrical devices that support the
information communication technology in the mid 21-th century.
Accordingly, it is quite important to have a broad knowledge of the
optical properties of advanced materials for students, scientists
and engineers working in optics and related fields. This book is
designed to teach fundamental optical properties of such advanced
materials effectively. These materials have their own peculiarities
which are very interesting in modern optical physics and also for
applications because the concepts of optical properties are quite
different from those in conventional optical materials. Hence each
chapter starts to review the basic concepts of the materials
briefly and proceeds to the practical use. The important topics
covered in this book include: quantum structures of semiconductors,
spintronics, photonic crystals, surface plasmons in metallic
nanostructures, photonic metamaterials, liquid crystal materials,
organic LED materials and magnet-optics.
This book introduces the use of industrial CMOS processes to produce arrays of nanomechanical cantilever transducers with on-chip driving and signal conditioning circuitry. These cantilevers are familiar from Scanning Probe Microscopy (SPM) and allow the sensitive detection of physical quantities such as forces and mass changes. The book is divided into three parts. First fabrication aspects and the mechanisms of cantilever resonators are introduced. Of the possible driving and sensing mechanisms, electrothermal and magnetic excitation, as well as piezoresistive detection and the use of MOS transistors for the deflection detection are introduced. This is followed by two application examples: The use of resonant cantilevers for the mass-sensitive detection of volatile organic compounds, and force sensor arrays for parallel Scanning Atomic Force Microscopy (AFM) of large areas.
Lissajous Figures are produced by combining two oscillations at
right angles to each other. The figures, drawn by mechanical
devices called Harmonographs, have scientific uses, but are also
enjoyed for their own beauty. The author has been working with
harmonographs since his undergraduate days, has built several of
them, lectured about them and has written articles about them. This
book is intended for people who enjoy physics or art or both.
Certainly physics professionals, both students and faculty members,
will enjoy reading about an interesting byway of physics. The book
is mainly designed for the reader who has some scientific literacy,
but who may not be a scientist. If your mathematics is rusty, a
preliminary section on mathematics supplies the necessary
background for reading the rest of the book.
The PUILS series delivers up-to-date reviews of progress in
Ultrafast Intense Laser Science, a newly emerging interdisciplinary
research field spanning atomic and molecular physics, molecular
science and optical science which has been stimulated by the recent
developments in ultrafast laser technologies. Each volume compiles
peer-reviewed articles authored by researchers at the forefront of
each their own subfields of UILS. Every chapter opens with an
overview of the topics to be discussed, so that researchers
unfamiliar to the subfield as well as graduate students can grasp
the importance and attractions of the research topic at hand. These
are followed by reports of cutting-edge discoveries. This eighth
volume covers a broad range of topics from this interdisciplinary
research field, focusing on molecules interacting with ultrashort
and intense laser fields, advanced technologies for the
characterization of ultrashort laser pulses and their applications,
laser plasma formation and laser acceleration.
