‘Mr Watson, come here, I want to see you.’
It’s been almost 150 years since Alexander Graham Bell said these
immortal words on the first ever phone call, to his assistant in the
next room. Between 10 March 1876 and now, the world has changed beyond
recognition. And telecommunications, which has played a fundamental
role in this change, has itself evolved into an industry that was the
sole preserve of science fiction.
When the world’s first modern mobile telephone network was launched in
1979, there were just over 300 million telephones. Today, there are
more than eight billion, most of which are mobile. Most people in most
countries can now contact each other in a matter of seconds. Soon we’ll
all be connected, to each other, and to complex computer networks that
provide us with instant information, but also observe and record our
actions. No other phenomenon touches so many of us, so directly, each
and every day of our lives.
This book describes how this transformation came about. It considers
the technologies that underpin telecommunications – microcircuits,
fibre-optics and satellites – and touches on financial aspects of the
industry: privatisations, mergers and takeovers that have helped shape
the $2-trillion telecom market. But for the most part, it’s a story
about us and our need to communicate.
Soft-Switching Technology for Three-phase Power Electronics
Converters Discover foundational and advanced topics in
soft-switching technology, including ZVS three-phase conversion In
Soft-Switching Technology for Three-phase Power Electronics
Converters, an expert team of researchers delivers a comprehensive
exploration of soft-switching three-phase converters for
applications including renewable energy and distribution power
systems, AC power sources, UPS, motor drives, battery chargers, and
more. The authors begin with an introduction to the fundamentals of
the technology, providing the basic knowledge necessary for readers
to understand the following articles. The book goes on to discuss
three-phase rectifiers and three-phase grid inverters. It offers
prototypes and experiments of each type of technology. Finally, the
authors describe the impact of silicon carbide devices on
soft-switching three-phase converters, studying the improvement in
efficiency and power density created via the introduction of
silicon carbide devices. Throughout, the authors put a special
focus on a family of zero-voltage switching (ZVS) three-phase
converters and related pulse width modulation (PWM) schemes. The
book also includes: A thorough introduction to soft-switching
techniques, including the classification of soft-switching for
three phase converter topologies, soft-switching types and a
generic soft-switching pulse-width-modulation known as Edge-Aligned
PWM A comprehensive exploration of classical soft-switching
three-phase converters, including the switching of power
semiconductor devices and DC and AC side resonance Practical
discussions of ZVS space vector modulation for three-phase
converters, including the three-phase converter commutation process
In-depth examinations of three-phase rectifiers with compound
active clamping circuits Perfect for researchers, scientists,
professional engineers, and undergraduate and graduate students
studying or working in power electronics, Soft-Switching Technology
for Three-phase Power Electronics Converters is also a must-read
resource for research and development engineers involved with the
design and development of power electronics.
Traffic Anomaly Detection presents an overview of traffic anomaly
detection analysis, allowing you to monitor security aspects of
multimedia services. The author's approach is based on the analysis
of time aggregation adjacent periods of the traffic. As traffic
varies throughout the day, it is essential to consider the concrete
traffic period in which the anomaly occurs. This book presents the
algorithms proposed specifically for this analysis and an empirical
comparative analysis of those methods and settle a new information
theory based technique, named "typical day analysis".
The communication field is evolving rapidly in order to keep up
with society's demands. As such, it becomes imperative to research
and report recent advancements in computational intelligence as it
applies to communication networks. The Handbook of Research on
Recent Developments in Intelligent Communication Application is a
pivotal reference source for the latest developments on emerging
data communication applications. Featuring extensive coverage
across a range of relevant perspectives and topics, such as
satellite communication, cognitive radio networks, and wireless
sensor networks, this book is ideally designed for engineers,
professionals, practitioners, upper-level students, and academics
seeking current information on emerging communication networking
trends.
Bio-inspired computation, especially those based on swarm
intelligence, has become increasingly popular in the last decade.
Bio-Inspired Computation in Telecommunications reviews the latest
developments in bio-inspired computation from both theory and
application as they relate to telecommunications and image
processing, providing a complete resource that analyzes and
discusses the latest and future trends in research directions.
Written by recognized experts, this is a must-have guide for
researchers, telecommunication engineers, computer scientists and
PhD students.
With the rapid progress in networking and computing technologies, a
wide variety of network-based computing applications have been
developed and deployed on the internet. Flexible and effective
service provisioning for supporting the diverse applications is a
key requirement for the next generation internet. However, the
current internet lacks sufficient capability for meeting this
requirement, mainly due to the ossification caused by tight
coupling between network architecture and infrastructure.
Service-Oriented Architecture (SOA), which has been widely adopted
in cloud computing via the Infrastructure-as-a-Service (IaaS),
Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS)
paradigms, may be applied in networking to decouple network
architecture and infrastructure; thus offering a promising approach
to addressing some fundamental challenges to the next generation
Internet. In general, such a service-oriented networking paradigm
is referred to as Network-as-a-Service (NaaS). This book presents
the state of the art of the NaaS paradigm, including its concepts,
architecture, key technologies, applications, and development
directions for future network service provisioning. It provides
readers with a comprehensive reference that reflects the most
current technical developments related to NaaS.
Are Information and Communications Technologies (ICTs) helpful or
detrimental to the process of design? According to Aristotle, the
imagination is a mental power that assists logical, sound
judgments. Design, therefore, incorporates both reason and
imagination. Challenging ICT Applications in Architecture,
Engineering, and Industrial Design Education posits imagination as
the central feature of design. It questions the common assumption
that ICTs are not only useful but also valuable for the creation of
the visual designs that reside at the core of architecture,
engineering design, and industrial design. For readers who believe
this assumption is right, this book offers an alternative
perspective.
