The fields of Big Data and the Internet of Things (IoT) have seen
tremendous advances, developments, and growth in recent years. The
IoT is the inter-networking of connected smart devices, buildings,
vehicles and other items which are embedded with electronics,
software, sensors and actuators, and network connectivity that
enable these objects to collect and exchange data. The IoT produces
a lot of data. Big data describes very large and complex data sets
that traditional data processing application software is inadequate
to deal with, and the use of analytical methods to extract value
from data. This edited book covers analytical techniques for
handling the huge amount of data generated by the Internet of
Things, from architectures and platforms to security and privacy
issues, applications, and challenges as well as future directions.
As the journey of quality is the journey of continual improvement,
that's why the author has tried his level best to make the study as
prolific as possible. The study is a quality step in the curriculum
engineering because quality textbooks play a dynamic role in the
holistic development of the young capital. The historical analysis
shows that nations sustain their ideologies through curriculum
up-gradation, synchronization, synthesis and innovation. Quality
Assurance in Textbook Development is based on TQM approach in
textbook development. The study is focused on the process of
applying tools for quality assurance in developing textbook for
primary level. In light of comparative study, analysis and
benchmarking of the curricula and review of textbooks of different
countries, attempt has been made to guide the process of textbook
development through flow charts, fish bone diagrams, gap analysis
and spider charts. The study also helps in need analysis, planning,
development and evaluation of quality textbook development.
Furthermore, the study provides some guiding principles which can
be employed purposefully for quality textbook development at any
level.
The amino and hydroxy anthraquinones possess numerous chemically
and biologically significant properties and as a group are also of
considerable practical importance in the production of dyes &
intermediates and as model compounds to gain fundamental
information. These derivatives of anthraquinones have found
important applications as prominent family of pharmaceutically
active and biologically relevant chromophores. A detailed and
comprehensive study of electronic absorption spectra of
anthraquinone and its hydroxy and amino derivatives and their
theoretical interpretation are presented. The effect of solvents on
the electronic absorption spectra of anthraquinones is studied
using twenty four solvents of different polarities. A careful study
of the effect of solvents on the electronic spectra of
anthraquinones reveals that the hydrogen bonding effects are of
considerable importance in understanding the spectral shifts in the
charge transfer transitions. The spectral shifts in various
solvents indicate that their values mainly depend on the strength
of the hydrogen bonds between the substituent groups and the
solvent molecules and the extent of the intramolecular hydrogen
bonding.
Semiconductor clusters have one extraordinarily important property
that on doping and on changes in size, their properties change
appreciably and in a controllable way. Current research into
semiconductor clusters is focused on the properties of thin films
having nanometre range grain size. The wide range of optical and
electrical properties of II-VI group compounds make them an
important class of materials and competing candidates for silicon
and other semiconductor materials in photovoltaic and
optoelectronic applications. In this monograph, the structural,
spectroscopic and optoelectronic properties of Cadmium Sulfide,
Cadmium Telluride and Zinc Oxide thin films are studied in detail.
The effects of substrate and grain size on structural and optical
properties of these materials are also discussed. Moreover, the
synthesis of CdS nanoparticles and fabrication of ZnO thin films by
the sol-gel methods and their spectroscopic characterization are
described. The ab-initio DFT calculations are carried for the
computations of the DOS and band structures of the CdS hexagonal
wurtzite, CdTe zinc blende and ZnO hexagonal wurtzite. Effect of Cd
dopping in ZnO is also studied theoretically.
Fullerenes are the third allotrope of carbon and have received much
attention due to their unique properties. In this monograph on
'Optical Gain and Relaxation Mechanism of Fullerenes in Solutions',
the effect of concentration of Fullerenes C60 and C70 molecules on
their fluorescence spectra are studied in detail. Moreover,
Forster's Resonance Energy Transfer (FRET) from different dyes to
the fullerenes are investigated and it has been found that
Fullerene C60 -Coumarin C440 pair and also Fullerene C70 -
Quinizarine pair may be used as spectroscopic rulers. Time Resolved
Spectra of both the fullerenes in pure as well as in mixture form
were measured and the results show that the optical gain is
concentration-dependent and only Fullerene C70 shows positive gain,
which can be used as a lasing material.
The world focusses on the gory aspects of the war on terror,
unmindful of a far more insidious form of combat taking place
elsewhere. It is an unglamorous but far more deadly war; the
warriors are pieces of digital code and the battlefield is
Cyberspace. E-Jihad is the story of that conflict. It traces the
origin of this form of warfare to the very same location from where
the first computer virus emerged; Pakistan. Unlike the virus which
was just a juvenile prank, the new code is designed for a specific
purpose; to fight evil. It is Jihad in its pristine form. This is
not a book, it is a magical flying carpet woven in words. Climb
aboard for an amazing journey across the world crisscrossing
Pakistan, Afghanistan, Europe, America, Asia and the Middle East.
As you travel this wondrous, convoluted route, learn how the first
digital warrior was deployed on the World Wide Web. Gain a stunning
insight into net-centric warfare and its evolution. Learn about
Islam, Muslims, Jihad and how the nature of War has changed.
E-Jihad is a work of fiction. You may elect to believe otherwise.
The book is about the anthropological inquiry in the domain of
politics, that would opened the way to delineate the ethnic issues
with ethnicists' and nationalists' own perspective. However, by
focusing on the role of intelligentsia and nationalists to conceive
nationalist doctrine and then made possible the outreach of that
doctrine is unique way of looking 'into past through present' by
focusing on the status of contemporary Saraiki nationalism. The
search for an ideological basis of the Pakistani state or nation
has to go beyond Islamic universalism and the two-nation theory and
look for a non-coercive territorial Pakistani identity born out of
the free interplay of diverse ethnic identities that throng the
Pakistani socio-cultural universe. However, the research is
comprehensive that not only enfolds the relationship of language
with identity, culture, ethnicity, and nationalism and emergence of
ethno-lingual nationalist movements along with real causes of
ethnicity in Pakistan, but also comprehensively understands the
emergence and establishment of Saraiki nationalism, the cultural,
political and administrative grievances of Saraiki community.
A supervisory hybrid control design approach is proposed for the
operation and control of a wind energy conversion and battery
storage system during grid-connected and in islanded operation. A
finite hybrid-automata based modeling paradigm for the system is
presented. The proposed model defines the allowable operating
states and inter-state transition paths managed by the supervisory
control layer. The subject system has been partitioned into three
independent system modules using a modular control design approach.
The supervisory control layer combines and configures control
schemes of the constituent modules to suite the requirements of
operation during any one operating state of the system. Transition
management strategies implemented through the supervisory control
layer ensure smooth inter-state transitions and bumpless switching
among regulators. Detailed mathematical models of the system are
provided in each operating state. Frequency domain linear analysis
and time domain electromagnetic transient simulations are presented
for the microgrid system under steady state and dynamic operating
conditions including temporary faults on the utility grid.
Electromagnetics for Electrical Machines offers a comprehensive yet
accessible treatment of the linear theory of electromagnetics and
its application to the design of electrical machines. Leveraging
valuable classroom insight gained by the authors during their
impressive and ongoing teaching careers, this text emphasizes
concepts rather than numerical methods, providing
presentation/project problems at the end of each chapter to enhance
subject knowledge. Highlighting the essence of electromagnetic
field (EMF) theory and its correlation with electrical machines,
this book: Reviews Maxwell's equations and scalar and vector
potentials Describes the special cases leading to the Laplace,
Poisson's, eddy current, and wave equations Explores the utility of
the uniqueness, generalized Poynting, Helmholtz, and approximation
theorems Discusses the Schwarz-Christoffel transformation, as well
as the determination of airgap permeance Addresses the skin effects
in circular conductors and eddy currents in solid and laminated
iron cores Contains examples relating to the slot leakage
inductance of rotating electrical machines, transformer leakage
inductance, and theory of hysteresis machines Presents analyses of
EMFs in laminated-rotor induction machines, three-dimensional field
analyses for three-phase solid rotor induction machines, and more
Electromagnetics for Electrical Machines makes an ideal text for
postgraduate-level students of electrical engineering, as well as
of physics and electronics and communication engineering. It is
also a useful reference for research scholars concerned with
problems involving electromagnetics.
