Communication has been one of the deepest needs of the human race throughout recorded
history. It is essential to forming social unions, to educating the young, and to expressing a
myriad of emotions and needs. Good communication is central to a civilized society.
The various communication disciplines in engineering have the purpose of providing technological
aids to human communication. One could view the smoke signals and drum rolls of primitive
societies as being technological aids to communication, but communication technology as we
view it today became important with telegraphy, then telephony, then video, then computer
communication, and today the amazing mixture of all of these in inexpensive, small portable
devices.
Many good textbooks exist on probability and random processes written at the under-
graduate level to the research level. However, there is no one handy and ready book
that explains most of the essential topics, such as random variables and most of their
frequently used discrete and continuous probability distribution functions; moments,
transformation, and convergences of random variables; characteristic and generating
functions; estimation theory and the associated orthogonality principle; vector random
variables; random processes and their autocovariance and cross-covariance functions; sta-
tionarity concepts; and random processes through linear systems and the associated
Wiener and Kalman filters.
This book provides the essential design techniques for radio systems that
operate at frequencies of 3 MHz to 100 GHz and which will be employed in
the telecommunication service. We may also call these wireless systems,
wireless being synonymous with radio, Telecommunications is a vibrant indus-
try, particularly on the ‘‘radio side of the house.’’ The major supporter of this
upsurge in radio has been the IEEE and its 802 committees. We now devote
? . an entire chapter to wireless LANs WLANs detailed in IEEE 802.11. We
also now have subsections on IEEE 802.15, 802.16, 802.20 and the wireless
? . ? metropolitan area network WMAN . WiFi, WiMax,, and UWB ultra wide-
. band are described where these comparatively new radio specialties are
demonstrating spectacular growth.
The Raspberry Pi has become a computing phenomenon. This single-board miniature
computer, first released in February 2012 by the Raspberry Pi Foundation, has grown into
a series of nearly a dozen models that have sold a total of more than 10 million units in
five years.
Inexpensive to buy and to run, Raspberry Pi computers are great for enthusiasts,
good for games, and fun for children. Raspberry Pi computers are also terrific in the
classroom, enabling you to put on each desk an easily-manageable computer on which
students can do everything from learning Internet use and essential office software skills,
through grasping programming basics in an easy-to-learn format, to performing full-on
programming in Python, Java, C, and other languages. Better yet, you can install all the
software needed for those activities automatically alongside the operating system.
In this research, we have designed, developed implemented a wireless sensor
networks based smart home for safe, sound and secured living environment for
any inhabitant especially elderly living alone. We have explored a methodology
for the development of efficient electronic real time data processing system to
recognize the behaviour of an elderly person. The ability to determine the
wellness of an elderly person living alone in their own home using a robust,
flexible and data driven artificially intelligent system has been investigated. A
framework integrating temporal and spatial contextual information for
determining the wellness of an elderly person has been modelled. A novel
behaviour detection process based on the observed sensor data in performing
essential daily activities has been designed and developed.
Electric distribution networks are critical parts of power delivery systems. In recent
years, many new technologies and distributed energy resources have been inte-
grated into these networks. To provide electricity at the possible lowest cost and at
required quality, long-term planning is essential for these networks. In distribution
planning, optimal location and size of necessary upgrades are determined to satisfy
the demand and the technical requirements of the loads and to tackle uncertainties
associated with load and distributed energy resources.
Switched systems are embedded devices widespread in industrial
applications such as power electronics and automotive control. They
consist of continuous-time dynamical subsystems and a rule that
controls the switching between them. Under a suitable control rule, the
system can improve its steady-state performance and meet essential
properties, such as safety and stability, in desirable operating zones.
This book introduces students to the theory and practice of control systems engineer-
ing. The text emphasizes the practical application of the subject to the analysis and
design of feedback systems.
The study of control systems engineering is essential for students pursuing
degrees in electrical, mechanical, aerospace, biomedical, or chemical engineering.
Control systems are found in a broad range of applications within these disciplines,
from aircraft and spacecraft to robots and process control systems.
