pandemics, optimizing contract tracing, and for detection and
diagnosis of diseases, among others. Written by researchers and
professionals with different backgrounds, this book offers a
extensive information and a source of inspiration for
physiologists, engineers, IT scientists and policy makers in the
health and technology sector.
The COVID-19 global pandemic has triggered health insecurity, food
insecurity, and economic insecurity among many others in South
Asia. It has profound impact on every sector of human activities
ranging from the economic to environment. There is a need for a
critical study of the implications of the COVID-19 pandemic for
human security in order to fathom the emerging theoretical and
policy issues in the region. Hence, the book provides an
understanding of the consequences of the COVID-19 global pandemic
for human security in South Asia. This intellectually stimulating
book provides a critical analysis and insights on this contemporary
challenge to policy makers, health professionals, academics,
students, researchers, NGO workers working with health, human
security and anyone interested in health and human security in
South Asia. The book covers major human security areas, i.e. health
security, food security, economic security, and environment issue.
The role of regional cooperation and global health governance is
also covered in the domain of COVID-19. This book fills the
existing knowledge gap on the human security in South Asia in
general and linking with COVID-19 in particular. From the
perspective of policy, the insights of the study would guide the
policy makers in South Asia in reframing their security policies
emphasising human security issues and challenges. Finally, this
book contributes to the evolving debate and discourse on the impact
of the COVID-19 on the South Asian region from a human security
perspective.
This stimulating book examines the key issues - including border
management, water cooperation, and connectivity - challenges and
possibilities in Bangladesh-India relations in the last fifty
years. The book also investigates the role of the 'China factor',
the role of civil society in Bangladesh-India relations and maps
out the future course of actions in Bangladesh-India partnership in
the post-pandemic world. The book contributes to both from
theoretical and policy perspective and therefore will be immensely
useful to the students of International Relations, Political
Science, to academics, researchers, and policymakers with interest
on Bangladesh-India relations, Bangladesh foreign policy, India's
foreign policy in particular, and South Asia in general.
The book reports the results of an impact assessment study of rural
libraries in Bangladesh. The main objective of this study was to
assess the performance and impact of rural libraries on rural
communities in Bangladesh. The book covers literature review
relating to user studies, rural information needs and seeking
behaviour and impact assessment studies, delineates rural library
projects in the developing and developed world, describes the
summary of focus group discussions (FGDs), discusses the rural
library situation in Bangladesh and presents summary of findings,
recommendations and conclusion. The results of this study showed
that rural library services have the potential to make a positive
impact on community development in Bangladesh. The results also
yielded several implications for rural libraries in Bangladesh,
including how their services could be improved to have even greater
impact on the communities they serve. Finally, the book proposes a
model plan for rural libraries which can be replicated to speed up
rural development in Bangladesh and beyond.
Cooperative communication allows several nodes to cooperatively
transmit signals to a particular destination. Using cooperative
communication, wireless networks could mitigate severe channel
impairments arising from multipath propagation. In this case, the
greater benefits are gained by exploiting spatial diversity in the
channel. In this book, an overview on cooperative communication in
wireless networks is presented. Practical issues and challenges in
cooperative communication are identified. Cooperative routing
strategies in different networks (wireless mesh networks, ad hoc
networks and wireless sensor networks) are discussed. However,
cooperative routing strategy in a network with multiple flows may
cause collision among helping nodes and thus, reduce the overall
system performance. In this book, a new routing protocol based on
new routing metric called Contention Sensitive Cooperative Metric
(CSCM) is discussed, which takes contention relationship into
consideration. Finally, the performance of the routing protocol has
been evaluated using simulation. The results demonstrate
significant performance improvement of cooperative communication
while using CSCM.
A Solar Home System includes Solar PV, battery, and solar charge
controller. In most cases solar energy consumer use solar energy at
evening hours, but it is available in day time. So, it is required
to store solar energy into battery. A solar charge controller, or
charge regulator is similar to the voltage regulator. It regulates
the voltage and current coming from the solar panels and goes to
the battery. Most of the batteries are fully charged at 14 to 14.5
volts. On the other hand, battery's life time drastically reduces
due to the discharge over the level of 70%-80% DOD; at this
discharge level the battery voltage normally goes down to 11.5 0.2
volts. Each battery has certain limit of capacity. Battery lifetime
reduces due to overcharging and deep discharging. As battery is a
very expensive component of Solar Home System. So, it is essential
to protect the batteries from over charging and deep discharging.
In this case charge controller plays a vital role to protect this
battery. The research aims to study the design and implementation
of a low cost solar charge controller."
The right to health has been widely recognized by States and
international organizations as fundamental human rights without
which sustainable human development can not be achieved. States are
responsible for the progressive realization of the rights to
health. This paper aims to examine the existing right to health
recognized in the national legislation of Bangladesh along with the
health system and policies. It reviews the right to health
mentioned in the international laws, defines case studies and
analyzes areas for improvement. This legal case study has been
based on literature review from primary and secondary sources and
experience gained through personal communication and group
discussions. The paper concludes that while Bangladesh has made
progress in some of the indicators of health, the realization of
right to health has not gained momentum and needs to be recognized
as a priority area. The recommendations of this legal case study
will help the policy makers of Bangladesh and other developing
countries to develop policies which will reduce the health
inequality and increased access to health for the entire
population.
The main concern of the study was to find out the real picture of
digital information resources among the university libraries of
Bangladesh. It also attempts to find out the existing
infrastructural facilities of the university libraries to run the
digital resources smoothly and also covers the users' behaviors and
knowledge status about digital information resources. Different
digitization and digital library attempts in the libraries of
Bangladesh are also taken place in the current study. The findings
and recommendations from the study should hopefully lead to
clarification of many problems in the formulation of planning and
policy making regarding digital information resources. The
researcher believes that it would help the librarians, policy
makers and concerned authority to develop and implement a suitable
system to accelerate digital resources in Bangladesh.
Efficient generation of combinatorial objects is a well-researched
area. Among them many literature devoted on the combinatorial Gray
code approach where the goal is to find a Hamiltonian path or cycle
in a representative graph of the corresponding combinatorial class.
Another approach namely genealogical tree approach has been
recently introduced where the goal is to find a rooted spanning
tree in the representative graph. Researchers have also focused on
finding general patterns in the generation techniques of
combinatorial classes so that common approaches can be applied to a
large number of related problems. Here, we propose a unifying
framework for combinatorial generation by giving recursive
definition of an abstract combinatorial class. The definition can
be instantiated to an array of specific combinatorial classes
namely n-tuple, combination, integer partition, set partition and
binary trees by specifying the framework parameters appropriately.
As an illustration, we show the instantiation of the combinatorial
class of n-tuples, combinations and balanced parenthesis strings
and also give novel constant-time generation algorithm for each of
them.
Optical amplifiers not only permit propagation of lightwave signals
over thousand of kilometers, they also enables the use of massive
WDM system and have led to the development of lightwave systems
with capacities exceeding 1Tb/s. Fiber nonlinearities plays a very
important role in designing such high capacity lightwave system.
Two such nonlinear effects, cross-phase modulation (XPM) and
self-phase modulation (SPM) are the prime subjects of concern in
this book. XPM and SPM are two phase modulation phenomena subjected
to the nonlinear intensity dependence of the core refractive index.
Dispersion causes these phase modulations to appear as intensity
variation of the propagating signal at the receiving end of the
system. This book is based on the extensive analytical study on
Cross-Phase Modulation (XPM) and Self-Phase Modulation (SPM), which
have a very significant effect on today's high speed DWDM system.
Throughout this book, the authors have presented their research
outcome and relevant theoretical overview. This book will help,
researchers and students who are working with the performance
analysis of optical system due to different fiber nonlinearities.
Deep linguistic processing is a research-intensive area with
several potential applications. Amidst the vast literature on
formal linguistic theory, Head- driven Phrase Structure Grammar
(HPSG) has a unique position, since it combines the best features
of the contemporary approaches as well as establishes an integrated
framework for cross-layer representation of linguistic objects.
There is very few HPSG analysis of Arabic morphological, syntactic
and semantic features. Arabic is the best instance of
nonconcatenative morphology among the living languages. Arabic verb
system shows a rich morphology, capable of lexically expressing
diverse syntactic and semantic phenomena. Formalisms of existing
morphological analyzers for Arabic cannot capture this higher layer
diversity due to a lack of mathematical rigor and expressiveness.
In this book, we discuss the HPSG framework to support rich
nonconcatenative morphology of Arabic verbs. We present HPSG
analysis of the agency of Arabic passives and reflexives as well as
morphologically complex predication of causatives in accordance
with the existing analysis in other languages.
