This book was born from the perception that there is much more to spectrum use
and sharing than one sees reflected in publications, whether academic, commercial
or political. the former – in good research style – tend towards reductionism and
concentrate on specific, detailed aspects. commercial publications tend to empha-
size the positive aspects and they tend to put promise above practice. Given the ever
increasing pace of technology development and recent successes of new wireless
technologies, some pundits predict large-Scale spectrum scarcity, potentially lead-
ing to economic catastrophe. Although economic theory has a hard time explaining
recent events that shook the world economy, the notion of spectrum scarcity is intui-
tively acceptable, even if not correct or immediately relevant.

This text, ESD Basics: From Semiconductor Manufacturing to Product Use was initiated on
the need to produce a text that addresses fundamentals of electrostatic discharge from the
manufacturing environment to today’s products. As the manufacturing world evolves, semi-
conductor networks Scale, and systems are changing, the needs and requirements for reliabi-
lity and ESD protection are changing. A text is required that connects basic ESD phenomena
to today’s real world environment.

As we enter the next millennium, there are clear technological patterns. First, the
electronic industry continues to Scale microelectronic structures to achieve faster
devices, new devices, or more per unit area. Secondly, electrostatic charge, electrostatic
discharge (ESD), electrical overstress (EOS) and electromagnetic emissions (EMI)
continue to be a threat to these Scaled structures. This dichotomy presents a dilemma
for the scaling of semiconductor technologies and a future threat to new technologies.
Technological advancements, material changes, design techniques, and simulation can
fend off this growing concern – but to maintain this ever-threatening challenge, one must
continue to establish research and education in this issue.

Micro-Electro-Mechanical Systems (MEMS) are miniature systems composed
ofintegratedelectricalandmechanicalpartstosenseand/orcontrolthingsonaμmScale.
The concept of MEMS is attributed to Richard Feynman’s famous talk on December
29th, 1959 [2,3]. Dr. Feynman foresaw many aspects of future MEMS development
with his insight in microphysics. In particular, material properties in the μm Scale are

The large-Scale deployment of the smart grid (SG) paradigm could play a strategic role in
supporting the evolution of conventional electrical grids toward active, flexible and self-
healing web energy networks composed of distributed and cooperative energy resources.
From a conceptual point of view, the SG is the convergence of information and
operational technologies applied to the electric grid, providing sustainable options to
customers and improved security. Advances in research on SGs could increase the
efficiency of modern electrical power systems by: (i) supporting the massive penetration
of small-Scale distributed and dispersed generators; (ii) facilitating the integration of
pervasive synchronized metering systems; (iii) improving the interaction and cooperation
between the network components; and (iv) allowing the wider deployment of self-healing
and proactive control/protection paradigms.

This book is written for engineers involved in the operation, control, and
planning of electric power systems. In addition, the book provides information and
tools for researchers working in the fields of power system security and stability. The
book consists of two volumes. The first volume provides traditional techniques for the
stability analysis of large Scale power systems. In addition, an overview of the main
drivers and requirements for modernization of the traditional methods for online
applications are discussed. The second volume provides techniques for online security
assessment and corrective action studies. In addition, the impact of variable generation
on the security of power systems is considered in the second volume. The first volume
may be considered as a background builder while the second volume is intended for
the coverage of edge techniques and methods for online dynamic security studies.

Battery systems for energy storage are among the most relevant technologies of the
21 st century. They – in particular modern lithium-ion batteries (LIB) – are enablers
for the market success of electric vehicles (EV) as well as for stationary energy
storage solutions for balancing fluctuations in electricity grids resulting from the
integrationofrenewableenergysourceswithvolatilesupply 1 .BothEVandstationary
storage solutions are important because they foster the transition from the usage
of fossil energy carriers towards cleaner renewable energy sources. Furthermore,
EV cause less local air pollution and noise emissions compared to conventional
combustion engine vehicles resulting in better air quality especially in urban areas.
Unfortunately, to this day, various technological and economic challenges impede a
broad application of batteries for EV as well as for large Scale energy storage and
load leveling in electricity grids.

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.
