Wireless networking is undergoing a transformation from what has
been primarily a medium for supporting voice traffic between telephones,
into what is increasingly becoming a medium for supporting traffic among
a variety of digital devices transmitting media of many types (voice,
data, images, video. etc.) Wireline networking underwent a similar
transformation in the 1990s, which led to an enormous build-up in the
capacity of such networks, primarily through the addition of new optical
fiber, switches and other infrastructure.

This book paves the path toward fourth generation (4G) mobile communica-
tion by introducing mobility in heterogeneous IP networks with both third
generation (3G) and wireless local area networks (WLANs), which is seen as
one of the central issues in the becoming 4G of telecommunications networks
and systems. This book presents a thorough overview of 3G networks and
standards and discusses interworking and handover mechanisms between
WLANs and the Universal Mobile Telecommunication System (UMTS).

Contamination and electrostatic discharge (ESD) are now becoming recognized as factors
affecting yield and reliability in an ever-increasing number of industries. Whereas contam-
ination traditionally was recognized as affecting the semiconductor, disk drive, aerospace,
pharmaceutical, and medical device industries, today such industries as automobile and
food production are also discovering the benefits of contamination control. ESD control
has experienced a similar growth in applications.

A revolution in power industries, including generation, transmission and distribution, driven by
environmental and economic considerations, is taking place all over the world. The smart grid allows for
integration of diverse generation and storage options, reduced losses, improved efficiencies, increased
grid flexibility, reduced power outages, allowing for competitive electricity pricing and integration of
electric vehicles and overall becoming more responsive to market, consumer and societal needs. It is
bringing profound changes to both power systems and many related industries.

Today, electric power transmission systems should face many demanding chal-
lenges, which include balancing between reliability, economics, environmental,
and other social objectives to optimize the grid assets and satisfy the growing
electrical demand.
Moreover, the operational environment of transmission systems is becoming
increasingly rigorous due to continually evolving functions of interconnected
power networks from operation jurisdiction to control responsibly – coupled with
the rising demand and expectation for reliability.

Radio frequency identifi cation (RFID) technology is a wireless communication
technology that enables users to uniquely identify tagged objects or people.
RFID is rapidly becoming a cost-effective technology. This is in large part
due to the efforts of Wal-Mart and the Department of Defense (DoD) to
incorporate RFID technology into their supply chains. In 2003, with the aim
of enabling pallet-level tracking of inventory, Wal-Mart issued an RFID
mandate requiring its top suppliers to begin tagging pallets and cases, with
Electronic Product Code (EPC) labels. The DoD quickly followed suit and
issued the same mandate to its top 100 suppliers. This drive to incorporate
RFID technology into their supply chains is motivated by the increased ship-
ping, receiving and stocking effi ciency and the decreased costs of labor, storage,
and product loss that pallet-level visibility of inventory can offer.

We are in the era of ubiquitous computing in which the use and development of Radio Frequency Iden-
tification (RFID) is becoming more widespread. RFID systems have three main components: readers,
tags, and database. An RFID tag is composed of a small microchip, limited logical functionality, and an
antenna. Most common tags are passive and harvest energy from a nearby RFID reader. This energy is
used both to energize the chip and send the answer back to the reader request. The tag provides a unique
identifier (or an anonymized version of that), which allows the unequivocal identification of the tag
holder (i.e. person, animal, or items).

In this new edition of the book, only minor changes were made to the original
nine chapters but three new chapters treat topics of increasing interest to GPS
users and equipment developers. One topic, improving the GPS receiver sensi-
tivity may extend their operations into buildings, which is becoming important
for emergency rescue and urban warfare.

Control systems are becoming more important every day. At the beginning, the in-
dustry used sequential controls for solving a lot of industrial applications in control
systems, and then the linear systems gave us a huge increase in applying automatic
linear control on industrial application. One of the most recent methods for control-
ling industrial applications is intelligent control, which is based on human behavior
or concerning natural process.

n recent years, there have been many books published on power system optimization.
Most of these books do not cover applications of artifi cial intelligence based methods.
Moreover, with the recent increase of artifi cial intelligence applications in various fi elds,
it is becoming a new trend in solving optimization problems in engineering in general
due to its advantages of being simple and effi cient in tackling complex problems. For this
reason, the application of artifi cial intelligence in power systems has attracted the interest
of many researchers around the world during the last two decades. This book is a result
of our effort to provide information on the latest applications of artifi cial intelligence
to optimization problems in power systems before and after deregulation.
