There have been significant developments in the field of numerical
methods for diffraction problems in recent years, and as a result,
it is now possible to perform computations with more than ten
million unknowns. However, the importance of asymptotic methods
should not be overlooked. Not only do they provide considerable
physical insight into diffraction mechanisms, and can therefore aid
the design of electromagnetic devices such as radar targets and
antennas, some objects are still too large in terms of wavelengths
to fall in the realm of numerical methods. Furthermore, very low
Radar Cross Section objects are often difficult to compute using
multiple methods. Finally, objects that are very large in terms of
wavelength, but with complicated details, are still a challenge
both for asymptotic and numerical methods. The best, but now widely
explored, solution for these problems is to combine various methods
in so called hybrid methods. Asymptotic and Hybrid Methods in
Electromagnetics is based on a short course, and presents recent
developments in the field.
The requirement of causality in system theory is inevitably
accompanied by the appearance of certain mathematical operations,
namely the Riesz proj-
tion,theHilberttransform,andthespectralfactorizationmapping.Aclassical
exampleillustratingthisisthedeterminationoftheso-calledWiener?lter(the
linear, minimum means square error estimation ?lter for stationary
stochastic sequences [88]). If the ?lter is not required to be
causal, the transfer function of the Wiener ?lter is simply given
by H(?)=? (?)/? (?),where ? (?) xy xx xx and ? (?) are certain
given functions. However, if one requires that the - xy timation
?lter is causal, the transfer function of the optimal ?lter is
given by 1 ? (?) xy H(?)= P ,?? (??,?] . + [? ] (?) [? ] (?) xx +
xx? Here [? ] and [? ] represent the so called spectral factors of
? ,and xx + xx? xx P is the so called Riesz projection. Thus,
compared to the non-causal ?lter, + two additional operations are
necessary for the determination of the causal ?lter, namely the
spectral factorization mapping ? ? ([? ] ,[? ] ),and xx xx + xx?
the Riesz projection P .
This book, in which the term granite is taken in its broadest
sense, collates the most innovative contributions that were
presented at the EUG 8 Meeting, X12 Symposium, held in Strasbourg
during April 1995. It covers a broad range of topics related to the
physical aspects of granite magmatism, which are largely
under-represented in comparison with chemical-oriented approaches.
Nineteen papers span the range from physical properties of granitic
material to several pluton case studies. The first part, Melt and
Magmas: Properties and Segregation', deals mainly with the physical
properties and segregation of melts and magmas, including
laboratory and field data. The second part, Fabrics in Granites',
develops some lively aspects of present-day granite geology, such
as magmatic fabrics at all scales, and analogue and numerical
experiments aimed at modelling magmatic fabrics. The third part,
Emplacement of Granite Plutons: Case Studies', begins with a
general consideration of syntectonic granites, includes a review of
the shape of plutons as inferred from combined fabric and gravity
data, and comprises some spectacular examples of plutons emplaced
along shear zones, in Spain, Sierra Nevada -California- (see the
cover page), Nigeria, and Brazil, or emplaced along subduction
zones, in Japan. Granite is the most abundant rock on the
continental crust, and this unique text is devoted entirely to the
understanding of its origins and emplacement by studying its
internal structures. The book is particularly well-illustrated, and
almost all the illustrations are original. It will serve as an
invaluable reference for geologists, petrologists, geophysicists
interested in the development of thecontinental crust and, more
generally, for earth scientists.
Managing Change is about implementing health care reforms, policies
and programs into everyday practices. The book explores
organizational change in health care as influenced by contemporary
policy and management concepts, and presents and applies
theoretical perspectives.
Robert Brandom's rationalist philosophy of language, expounded in
his highly influential Making It Explicit, has been the subject of
intense scrutiny and debate, establishing him as one of the leading
philosophers of his generation. In A Spirit of Trust, Brandom
presents the fruits of his thirty-year engagement with Hegel. He
submits that the Phenomenology of Spirit holds not only many
lessons for today's philosophy of language, but also a moral lesson
much needed in today's increasingly polarized societies, in the
form of a postmodern ethics of trust. In this outstanding
collection, leading philosophers examine and assess A Spirit of
Trust. The twelve specially commissioned chapters explore topics
including: negation and truth empirical and speculative concepts
experience conflict and recognition varieties of idealism premodern
ethical life and modern alienation a postmodern ethics of trust.
Reading Brandom: On A Spirit of Trust is essential reading for all
students and scholars of Brandom's work and those in philosophy of
language. It will also be important reading for those studying
nineteenth-century philosophy, particularly Hegel and the
Phenomenology of Spirit.
The increasing urgency of environmental issues necessitates the
rethinking of our societal model. This book explores this assertion
by going back in time and pinpointing the turning points in the
evolution of European society that we are currently experiencing.
Productive Economy, Contributory Economy presents an analysis of
the factors affecting the evolution of our societal model, emerging
from sedentarism, which culminated in the industrial age. To
further this evolution, we must allow the common good to prosper:
family, knowledge, innovation, democracy and spirituality. This
book presents a dual contributory and productive economy to be put
into place, as well as the synergy that can be established between
these two spaces of human contribution. It also studies the
instruments of governance that we will need, such as smart money,
as well as the conditions of their success.
This book provides a tutorial on quantum communication networks.
The authors discuss current paradigm shifts in communication
networks that are needed to add computing and storage to the simple
transport ideas of prevailing networks. They show how these
'softwarized' solutions break new grounds to reduce latency and
increase resilience. The authors discuss how even though these
solutions have inherent problems due to introduced computing
latency and energy consumption, the problems can be solved by
hybrid classical-quantum communication networks. The book brings
together quantum networking, quantum information theory, quantum
computing, and quantum simulation.
The purpose of this book is to provide tools for a better
understanding of the fundamental tradeo's and interdependencies in
wireless networks, with the goal of designing resource allocation
strategies that exploit these int- dependencies to achieve
signi?cant performance gains. Two facts prompted us to write it:
First, future wireless applications will require a fundamental
understanding of the design principles and control mechanisms in
wireless networks. Second, the complexity of the network problems
simply precludes the use of engineering common sense alone to
identify good solutions, and so mathematics becomes the key avenue
to cope with central technical problems in the design of wireless
networks. In this book, two ?elds of mathematics play a central
role: Perron-Frobenius theory for non-negative matrices and
optimization theory. This book is a revised and expanded version of
the research monograph "Resource Allocation in Wireless Networks"
that was published as Lecture Notes in Computer Sciences (LNCS
4000) in 2006. Although the general structure has remained
unchanged to a large extent, the book contains - merous additional
results and more detailed discussion. For instance, there is a more
extensive treatment of general nonnegative matrices and interf-
ence functions that are described by an axiomatic model. Additional
material on max-min fairness, proportional fairness, utility-based
power control with QoS (quality of service) support and stochastic
power control has been added.
Since publication of the initial papers in 2006, compressed sensing
has captured the imagination of the international signal processing
community, and the mathematical foundations are nowadays quite well
understood. Parallel to the progress in mathematics, the potential
applications of compressed sensing have been explored by many
international groups of, in particular, engineers and applied
mathematicians, achieving very promising advances in various areas
such as communication theory, imaging sciences, optics, radar
technology, sensor networks, or tomography. Since many applications
have reached a mature state, the research center MATHEON in Berlin
focusing on "Mathematics for Key Technologies", invited leading
researchers on applications of compressed sensing from mathematics,
computer science, and engineering to the "MATHEON Workshop 2013:
Compressed Sensing and its Applications" in December 2013. It was
the first workshop specifically focusing on the applications of
compressed sensing. This book features contributions by the plenary
and invited speakers of this workshop. To make this book accessible
for those unfamiliar with compressed sensing, the book will not
only contain chapters on various applications of compressed sensing
written by plenary and invited speakers, but will also provide a
general introduction into compressed sensing. The book is aimed at
both graduate students and researchers in the areas of applied
mathematics, computer science, and engineering as well as other
applied scientists interested in the potential and applications of
the novel methodology of compressed sensing. For those readers who
are not already familiar with compressed sensing, an introduction
to the basics of this theory will be included.

The fifth volume of Rudolf Ahlswede's lectures on Information
Theory focuses on several problems that were at the heart of a lot
of his research. One of the highlights of the entire lecture note
series is surely Part I of this volume on arbitrarily varying
channels (AVC), a subject in which Ahlswede was probably the
world's leading expert. Appended to Part I is a survey by Holger
Boche and Ahmed Mansour on recent results concerning AVC and
arbitrarily varying wiretap channels (AVWC). After a short Part II
on continuous data compression, Part III, the longest part of the
book, is devoted to distributed information. This Part includes
discussions on a variety of related topics; among them let us
emphasize two which are famously associated with Ahlswede:
"multiple descriptions", on which he produced some of the best
research worldwide, and "network coding", which had Ahlswede among
the authors of its pioneering paper. The final Part IV on
"Statistical Inference under Communication constraints" is mainly
based on Ahlswede's joint paper with Imre Csiszar, which received
the Best Paper Award of the IEEE Information Theory Society. The
lectures presented in this work, which consists of 10 volumes, are
suitable for graduate students in Mathematics, and also for those
working in Theoretical Computer Science, Physics, and Electrical
Engineering with a background in basic Mathematics. The lectures
can be used either as the basis for courses or to supplement them
in many ways. Ph.D. students will also find research problems,
often with conjectures, that offer potential subjects for a thesis.
More advanced researchers may find questions which form the basis
of entire research programs.
This contributed volume contains articles written by the plenary
and invited speakers from the second international MATHEON Workshop
2015 that focus on applications of compressed sensing. Article
authors address their techniques for solving the problems of
compressed sensing, as well as connections to related areas like
detecting community-like structures in graphs, curbatures on
Grassmanians, and randomized tensor train singular value
decompositions. Some of the novel applications covered include
dimensionality reduction, information theory, random matrices,
sparse approximation, and sparse recovery. This book is aimed at
both graduate students and researchers in the areas of applied
mathematics, computer science, and engineering, as well as other
applied scientists exploring the potential applications for the
novel methodology of compressed sensing. An introduction to the
subject of compressed sensing is also provided for researchers
interested in the field who are not as familiar with it.
This book develops a mathematical framework for modeling and
optimizing interference-coupled multiuser systems. At the core of
this framework is the concept of general interference functions,
which provides a simple means of characterizing interdependencies
between users. The entire analysis builds on the two core axioms
scale-invariance and monotonicity.
The proposed network calculus has its roots in power control theory
and wireless communications. It adds theoretical tools for
analyzing the typical behavior of interference-coupled networks. In
this way it complements existing game-theoretic approaches.
The framework should also be viewed in conjunction with
optimization theory. There is a fruitful interplay between the
theory of interference functions and convex optimization theory. By
jointly exploiting the properties of interference functions, it is
possible to design algorithms that outperform general-purpose
techniques that only exploit convexity.
The title "network calculus" refers to the fact that the theory of
interference functions constitutes a generic theoretical framework
for the analysis of interference coupled systems. Certain
operations within the framework are "closed," that is, combinations
of interference functions are interference functions again. Also,
certain properties are preserved under such operations. This,
provides a methodology for analyzing different multiuser
performance measures that can be expressed as interference
functions or combinations of interference functions.
