Over many years, RF-MEMS have been a hot topic in research at the technology
and device level. In particular, various kinds of mechanical Si-MEMS resonators
and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The
BAW technology has made its way to commercial products for passive RF filters,
in particular for duplexers in RF transceiver front ends for cellular communica-
tions. Beyond their use in filters, micromachined resonators can also be used in
conjunction with active devices in innovative circuits and architectures.

Since the 1990s the EU has been pursuing climate change mitigation targets. Following the
international commitment to the legally binding greenhouse gas reduction under the Kyoto
Protocol, the 2020 policy package consists of a set of binding legislation to ensure that the EU
meets its climate and energy targets for the year 2020. The package sets three key targets: 20%
reduction in greenhouse gas emissions (from 1990 levels), 20% of EU energy from renewables (as
well as a 10% target for renewable fuels) and 20% improvement in energy efficiency. The targets
were set by EU leaders in 2007 and enacted in legislation in 2009 3 . They are also headline targets of
the Europe 2020 strategy for smart, sustainable and inclusive growth.

Resource allocation is an important issue in wireless communication networks. In
recent decades, cognitive radio technology and cognitive radio-based networks have
obtained more and more attention and have been well studied to improve spectrum
utilization and to overcomethe problem of spectrum scarcity in future wireless com-
munication systems. Many new challenges on resource allocation appear in cogni-
tive radio-based networks. In this book, we focus on effective solutions to resource
allocation in several important cognitive radio-based networks, including a cogni-
tive radio-basedopportunisticspectrum access network, a cognitiveradio-basedcen-
tralized network, a cognitive radio-based cellular network, a cognitive radio-based
high-speed vehicle network, and a cognitive radio-based smart grid.

This book is intended for researchers, teachers, and students willing to ex-
plore conceptual bridges between the fields of Automatic Control and Power
Electronics. The need to bring the two disciplines closer has been felt, for
many years, both by Power Electronics specialists and by Automatic Control
theorists, as a means of fruitful interaction between the two scientific com-
munities. There have, certainly, been many steps given in that direction in
the last decade as evidenced by the number of research articles in journals,
special sessions in conferences, and summer courses throughout the world.

This book provides a comprehensive overview of the technology behind the pico-solar revolution
and offers guidance on how to test and choose quality products. The book also discusses how
pioneering companies and initiatives are overcoming challenges to reach scale in the market-
place, from innovative distribution strategies to reach customers in rural India and Tanzania,
to product development in Cambodia, product assembly in Mozambique and the introduction
of ‘pay as you go’ technology in Kenya.

The purpose of this book is to help anyone involved in small-scale geophys-
ical surveys. It is not a textbook in the traditional sense, in that it is designed
for use in the field and concerns itself with practical matters – with the-
ory taking second place. Where theory determines field practice, it is stated,
not developed or justified. For example, no attempt is made to explain why
four-electrode resistivity works where two-electrode surveys do not.

Computer science as an academic discipline began in the 1960’s. Emphasis was on
programming languages, compilers, operating systems, and the mathematical theory that
supported these areas. Courses in theoretical computer science covered finite automata,
regular expressions, context-free languages, and computability. In the 1970’s, the study
of algorithms was added as an important component of theory. The emphasis was on
making computers useful. Today, a fundamental change is taking place and the focus is
more on a wealth of applications. There are many reasons for this change. The merging
of computing and communications has played an important role. The enhanced ability
to observe, collect, and store data in the natural sciences, in commerce, and in other
fields calls for a change in our understanding of data and how to handle it in the modern
setting. The emergence of the web and social networks as central aspects of daily life
presents both opportunities and challenges for theory.

Much has been written concerning the manner in which healthcare is changing, with
a particular emphasis on how very large quantities of data are now being routinely
collected during the routine care of patients. The use of machine learning meth-
ods to turn these ever-growing quantities of data into interventions that can improve
patient outcomes seems as if it should be an obvious path to take. However, the
field of machine learning in healthcare is still in its infancy. This book, kindly
supported by the Institution of Engineering andTechnology, aims to provide a “snap-
shot” of the state of current research at the interface between machine learning and
healthcare.

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
