This book collects the latest theoretical and technological
concepts in the design and control of various linear machines and
drive systems. Discussing advances in the new linear machine
topologies, integrated modeling, multi-objective optimization
techniques, and high-performance control strategies, it focuses on
emerging applications of linear machines in transportation and
energy systems. The book presents both theoretical and
practical/experimental results, providing a consistent compilation
of fundamental theories, a compendium of current research and
development activities as well as new directions to overcome
critical limitations.
This book discusses a number of important topical technical and
non-technical issues related to the global energy, environment and
socio-economic developments for professionals and students directly
and indirectly involved in the relevant fields. It shows how
renewable energy offers solutions to mitigate energy demand and
helps achieve a clean environment, and also addresses the lack of a
clear vision in the development of technology and a policy to reach
the mandatory global renewable energy targets to reduce greenhouse
gas emissions and stimulate socio-economic development. The book is
structured in such a way that it provides a consistent compilation
of fundamental theories, a compendium of current research and
development activities as well as new directions to overcome
critical limitations; future technologies for power grids and their
control, stability and reliability are also presented.

This book examines a number of topics, mainly in connection with
advances in semiconductor devices and magnetic materials and
developments in medium and large-scale renewable power plant
technologies, grid integration techniques and new converter
topologies, including advanced digital control systems for
medium-voltage networks. The book's individual chapters provide an
extensive compilation of fundamental theories and in-depth
information on current research and development trends, while also
exploring new approaches to overcoming some critical limitations of
conventional grid integration technologies. Its main objective is
to present the design and implementation processes for
medium-voltage converters, allowing the direct grid integration of
renewable power plants without the need for step-up transformers.
To meet the increasing demand of electrical power, the use of
renewable energy-based smart grid is attracting significant
attention in recent years throughout the world. The high
penetration of renewable power in the smart grids is growing its
importance due to its non-finishing, reusable, reliable,
sustainable, lower cost, and available characteristics. The
renewable energy-based smart grid technology may mitigate the
increasing energy demands effectively and efficiently without
hampering the environment. But the uncertain nature of renewable
sources largely affects the operation of the smart grid by
un-stabling the voltage and frequency that may introduces power
quality and reliability problems, which requires special control
techniques. This book investigates the challenges in controlling
renewable energy-based smart grids and proposes different control
techniques to control the voltage and frequency effectively to
improve the power quality and reliability of the power grids. This
book is a valuable resource for readers interested in practical
solutions in smart grids and renewable energy systems.

Hijras of Bangladesh such a minority groups, who suffered from
enormous discrimination, should be called as gender discrimination.
They suffer from different types of social and political
marginalization. The policy makers have never seriously paid any
attention to their problems. The study design was a combination of
survey, observation, FGD and case study. Hijras of Bangladesh are
in a vulnerable position in all aspect of social life. Lack of
education is a major problem for them, because of which they are
not aware of their Human Rights. Because of their different
behaviour, they are neglecting from shelter, work, education and
expression of their own. Throughout this paper, author has
attempted to understand Hijras as they defined themselves. The
facts tried to explore in this study under the title of 'Social
Life of Hijras: A Study from Khulna City of Bangladesh' are mostly
associated with their social life and their problems in daily life.
Automatic Speech Recognition (ASR) has progressed considerably over
the past several decades, but still has not achieved the potential
imagined at its very beginning. Almost all of the existing
applications of ASR systems are PC based. This work is an attempt
to develop a speech recognition system that is independent of any
PC support and is small enough in size to be used in a daily use
consumer appliance. The proposed system would recognize isolated
word utterances from a limited vocabulary, provide speaker
independence, require less memory and be cost-efficient compared to
present ASR systems. In this system, isolated word recognition is
performed by using Vector Quantization (VQ) and Mel-Frequency
Cepstral Coefficient (MFCe. The final system has been implemented
on a vero board with an ATMEGA32 microcontroller. Learning and
recognition algorithm have been used to recognize the speech
utterances.
