This book analyzes the impact of scientific computing
in science and society over the coming decades. It presents
advanced methods that can provide new possibilities to
solve scientific problems and study important phenomena in
society. The chapters cover Scientific computing as the third
paradigm of science as well as the impact of scientific computing
on natural sciences, environmental science, economics, social
science, humanistic science, medicine, and engineering. Moreover,
the book investigates scientific computing in high performance
computing, quantum computing, and artificial intelligence
environment and what it will be like in the 2030s and 2040s.
This volume studies electron resonant tunneling in two- and
three-dimensional quantum waveguides of variable cross-sections in
the time-independent approach. Mathematical models are suggested
for the resonant tunneling and develop asymptotic and numerical
approaches for investigating the models. Also, schemes are
presented for several electronics devices based on the phenomenon
of resonant tunneling. Devices based on the phenomenon of electron
resonant tunneling are widely used in electronics. Efforts are
directed towards refining properties of resonance structures. There
are prospects for building new nano size electronics elements based
on quantum dot systems. However, the role of resonance structure
can also be given to a quantum wire of variable cross-section.
Instead of an "electrode - quantum dot - electrode" system, one can
use a quantum wire with two narrows. A waveguide narrow is an
effective potential barrier for longitudinal electron motion along
a waveguide. The part of the waveguide between two narrows becomes
a "resonator" , where electron resonant tunneling can occur. This
phenomenon consists in the fact that, for an electron with energy
E, the probability T(E) to pass from one part of the waveguide to
the other part through the resonator has a sharp peak at E = Eres,
where Eres denotes a "resonant" energy. Such quantum resonators can
find applications as elements of nano electronics devices and
provide some advantages in regard to operation properties and
production technology. The book is addressed to mathematicians,
physicists, and engineers interested in waveguide theory and its
applications in electronics.
This book deals with theoretical aspects of modelling the
mechanical behaviour of manufacturing, processing, transportation
or other systems in which the processed or supporting material is
travelling through the system. Examples of such applications
include paper making, transmission cables, band saws, printing
presses, manufacturing of plastic films and sheets, and extrusion
of aluminium foil, textiles and other materials. The work focuses
on out-of-plane dynamics and stability analysis for isotropic and
orthotropic travelling elastic and viscoelastic materials, with and
without fluid-structure interaction, using analytical and
semi-analytical approaches. Â Also topics such as fracturing
and fatigue are discussed in the context of moving materials. The
last part of the book deals with optimization problems involving
physical constraints arising from the stability and fatigue
analyses, including uncertainties in the parameters. The book is
intended for researchers and specialists in the field, providing a
view of the mechanics of axially moving materials. It can also be
used as a textbook for advanced courses on this specific topic.
Considering topics related to manufacturing and processing, the
book can also be applied in industrial mathematics.
The importance of accuracy verification methods was understood at
the very beginning of the development of numerical analysis. Recent
decades have seen a rapid growth of results related to adaptive
numerical methods and a posteriori estimates. However, in this
important area there often exists a noticeable gap between
mathematicians creating the theory and researchers developing
applied algorithms that could be used in engineering and scientific
computations for guaranteed and efficient error control. Â
The goals of the book are to (1) give a transparent explanation of
the underlying mathematical theory in a style accessible not only
to advanced numerical analysts but also to engineers and students;
(2) present detailed step-by-step algorithms that follow from a
theory; (3) discuss their advantages and drawbacks, areas of
applicability, give recommendations and examples.
This book focus on critical infrastructure protection. The chapters
present detailed analysis of the issues and challenges in
cyberspace and provide novel solutions in various aspects. The
first part of the book focus on digital society, addressing
critical infrastructure and different forms of the digitalization,
strategic focus on cyber security, legal aspects on cyber security,
citizen in digital society, and cyber security training. The second
part focus on the critical infrastructure protection in different
areas of the critical infrastructure. The chapters cover the
cybersecurity situation awareness, aviation and air traffic
control, cyber security in smart societies and cities, cyber
security in smart buildings, maritime cyber security, cyber
security in energy systems, and cyber security in healthcare. The
third part presents the impact of new technologies upon cyber
capability building as well as new challenges brought about by new
technologies. These new technologies are among others are quantum
technology, firmware and wireless technologies, malware analysis,
virtualization.
This volume contains thirteen articles on advances in applied
mathematics and computing methods for engineering problems. Six
papers are on optimization methods and algorithms with emphasis on
problems with multiple criteria; four articles are on numerical
methods for applied problems modeled with nonlinear PDEs; two
contributions are on abstract estimates for error analysis; finally
one paper deals with rare events in the context of uncertainty
quantification. Applications include aerospace, glaciology and
nonlinear elasticity. Herein is a selection of contributions
from speakers at two conferences on applied mathematics held in
June 2012 at the University of Jyväskylä, Finland. The first
conference, “Optimization and PDEs with Industrial
Applications” celebrated the seventieth birthday of Professor
Jacques Périaux of the University of Jyväskylä and
Polytechnic University of Catalonia (Barcelona Tech) and the second
conference, “Optimization and PDEs with Applications”
celebrated the seventy-fifth birthday of Professor Roland Glowinski
of the University of Houston. This work should be of interest to
researchers and practitioners as well as advanced students or
engineers in computational and applied mathematics or mechanics.
