Work with individual atoms and molecules aims to demonstrate
that miniaturized electronic, optical, magnetic, and mechanical
devices can operate ultimately even at the level of a single atom
or molecule. As such, atomic and molecular manipulation has played
an emblematic role in the development of the field of nanoscience.
New methods based on the use of the scanning tunnelling microscope
(STM) have been developed to characterize and manipulate all the
degrees of freedom of individual atoms and molecules with an
unprecedented precision. In the meantime, new concepts have emerged
to design molecules and substrates having specific optical,
mechanical and electronic functions, thus opening the way to the
fabrication of real nano-machines. Manipulation of individual atoms
and molecules has also opened up completely new areas of research
and knowledge, raising fundamental questions of "Optics at the
atomic scale," "Mechanics at the atomic scale," Electronics at the
atomic scale," "Quantum physics at the atomic scale," and
"Chemistry at the atomic scale." This book aims to illustrate the
main aspects of this ongoing scientific adventure and to anticipate
the major challenges for the future in "Atomic and molecular
manipulation" from fundamental knowledge to the fabrication of
atomic-scale devices.

Resource allocation in wireless networks is traditionally
approached either through information theory or communications
networks. To break down the barriers between these distinct
approaches, this book (whose preparation is carried out under the
auspices of the EC Network of Excellence in Wireless Communications
NEWCOM++) bridges the physical and network layers by providing
cross-layer resource allocation techniques, models and
methodologies.
Cross-Layer Resource Allocation's unique approach allows
optimisation of network resources and will enable engineers to
improve signal quality, enhance network and spectrum utilization,
increase throughput, and solve the problem of shadowing. Topics
covered include different views of spectral efficiency, the role of
spatial diversity, of delay in resource allocation, and possible
extensions to OFDMA systems.
This will be an ideal reference on cross-layer resource allocation
between the PHY and MAC layers for R&D and network design
engineers and researchers in universities dealing with sensor
networks and cognitive systems.

type of measurements used, together with samples of the performance
measurements attained.
The book will enable you to answer vital questions such as:
* How long will my network remain alive given the amount of sensing
required of it?
* For how long should I set the sleeping state of my motes?
* How many sensors should I distribute to meet the expected
requirements of the application?
* What type of throughput should I expect as a function of the
number of nodes deployed and the radio interface chosen (whether it
be Bluetooth or Zigbee)?
* How is the Packet Error Rate of my Zigbee motes affected by the
selection of adjacent frequency sub bands in the ISM 2.4GHz
band?

A large amount of natural or artificially produced physical
phenomena are exploited for practical applications, even though
several of them give rise to unpleasant consequences. These
ultimately manifest themselves under form of malfunction or
definitive failure of components and systems, or environmental
hazard. So far, manifold categories of inadvertent or deliberate
sources have been discovered to simultaneously produce useful
effects in some ways but adverse ones in others. In particular,
responsible for the growing interest in the last decades for
Electromagnetic Compatibility (EMC) has been the progressive
miniaturisation and sensitivity of electronic components and
circuits, often operating in close proximity to relatively powerful
sources of electromagnetic interference. Potential authors of books
on the subject-matter are fully aware of the fact that planning
production of manageable handbooks capable to treat all the EMC
case studies of practical and long-lasting interest could result in
a questionable and difficult undertaking. Therefore, in addition to
textbooks providing a thorough background on basic aspects, thus
being well-tailored for students and those which want to get in
contact with this discipline, the most can be made to jointly
sustain a helpful and practicable publishing activity is to supply
specialised monographs or miscellanies of selected topics. Such
resources are preferentially addressed to post-graduate students,
researchers and designers, often employed in the forefront of
research or engaged for remodelling design paradigms. Hence, the
prerequisite for such a class of publications should consist in
arousing critical sense and promoting new ideas. This is the object
of the present book which tries to rather discuss special subjects,
or throw out suggestions for reformulating conventional approaches,
than to appear as a reference text. A common motivation encouraged
the contributors to bringing together a number of accounts of the
research that they have undertaken over the late years: willing to
fill the important need of covering EMC topics rather proper to
transmission and distribution of electric power than, more usually,
to Electronics and Telecommunication Systems.
- EMC topics for Power Systems, at last
- Investigating EMC features of distributed and/or complex
systems.
- A broad body of knowledge for specific applications.
- A stimulating support for those which are engaged in the
forefront of research and design.
- An example of how breaking ideas should be encouraged and proudly
applied.
- A fruitful critique to overcomplicated and unpractical
models.
- A comprehensive resource to estimate the important role of EMC at
lower frequencies.
Since the 1970's, there has been a great deal of research effort
spent on studying
chaotic systems and the properties of the chaotic signals
generated. Characterized by their wideband, impulse-like
autocorrelation and low cross-correlation properties, chaotic
signals are useful spread-spectrum signals for carrying digital
information. Spectrum spreading has become one of the most popular
modulation techniques for high-speed wireless communications. It
makes use of signals of very wide bandwidth to carry information at
relatively low data rates, and possesses advantages such as low
probability of interception, resistance to jamming, multiple-access
capability and mitigation to multipath effect, which are
particularly important in a wireless scenario. In addition to
enjoying the aforementioned benefits, chaotic signals can be
generated using simple circuitries, thus lowering the cost of
transceivers.
Early study of chaos-based communication systems was focused on a
single-user case. In the past few years, more effort has been put
on investigating systems with multiple-access capability, which is
a key feature of spread-spectrum communication systems. This book
presents a detailed study of some multiple-access schemes used for
chaos-based communications, and evaluates their performance. In
addition, the effectiveness of the multiuser detection techniques,
whose primary objective is to reduce interference between users and
hence improve performance, is evaluated in the context of
multiple-access digital communication systems.
* Hot research topic
