For junior or senior undergraduate students in Electrical and
Electronic Engineering. This text covers the basics of emerging
areas in power electronics and a broad range of topics such as
power switching devices, conversion methods, analysis and
techniques, and applications. Its unique approach covers the
characteristics of semiconductor devices first, then discusses the
applications of these devices for power conversions. Four main
applications are included: flexible ac transmissions (FACTs),
static switches, power supplies, dc drives, and ac drives.
This book is a comprehensive collection of chemical engineering
terms in a single volume. It covers generally all the chemical
engineering literature and has distinguished features. The book is
a useful reference material for the people both at the schools and
the industry. The author's experience of teaching and research over
the years has realized a must book of this kind. The terms are
written in alphabetical order. Where a term deserves more
elaboration, a rather detailed description is provided. The book
also contains a number of labeled diagrams which may be helpful in
understanding some critical terms.
Triticale (Triticosecale) a hybrid of wheat (Triticum) and rye
(Secale) is an important cereal crop and has more production as
compared to wheat. It has gained importance in fulfilling the
increased food demands of the world. For a breeding programme
genetic variability and the genetic relationship among genotypes is
important. To study this, 70 lines of triticale introduced from
CIMMYT were planted in complete block design. Data was recorded for
plant height, spike length, number of spikelets per spike, number
of grains per spike, number of tillers per meter, grain yields per
meter and 1000 grain weight. The data showing significant
differences was subjected correlation and cluster analysis.
Correlation analysis gave the results that plant height had
negative and non-significant correlation with grain yield per
meter. It was found that spike length had positive and significant
correlation with grain yield per meter. Number of spikelets per
spike and grain yield per meter was reported to have positive and
significant correlation whereas number of grains per spike had
positive and highly significant correlation.
Pea (Pisum sativum L.) is a green pod-bearing plant belongs to
family leguminosae. Peas are highly rich in protein, manganese,
dietary fiber, vitamin C, vitamin K, vitamin B1 and folate. The
high amount of vitamin K1 from green peas makes them very important
for bone health. Peas are widely grown as a cool season vegetable
crop. Pea plants are highly sensitive to the summer heat. Moringa
leaf is also a rich source of ascorbates, carotenoids, phenolics,
potassium and calcium which have plant growth promoting
capabilities and are being applied as exogenous plant growth
enhancers. Antioxidants such as ascorbic acid and glutathione,
which are found at high concentrations in moringa chloroplasts and
other cellular compartments, are crucial for plant defense against
oxidative stress. It is therefore hypothesized that leaf extract
from moringa, having a number of plant growth promoters, mineral
nutrients and vitamins in a naturally balanced composition, which
may promote the pea growth and extend its fruit bearing period.
This study was conducted to monitor the impact of exogenous
application of MLE (moringa leaf extract) on the growth and yield
performance of pea.
This book covers almost every aspect of training and development.
It explains basic concepts of training and development, why
training is necessary? the training methods, activities, exercises,
case studies and role plays use to train employees. In this book
every topic is explained in detail along with discussion exercises
and web links for further reading for each topic given at the end
of every topic. Web links for each topic consists of video
lectures, power point slides, web texts and the like. Besides this,
every topic has it's diagrammatic model at the end of each topic.
These models help readers to have overview of a topic at a single
glance.
Fruit production has been the earliest of food sources meeting the
needs of human race for centuries. Owing to varied climate under
the sun, the fruit production has also got wide range in fruit
types, nutritional values and production technologies. Citriculture
has emerged as one of the major fruit production industries in the
world. Like the other fruits, citrus is known for its versatility
in use. It is used as fresh fruit, its peel is used for the
extraction of essential oils, pulp in extraction of juices and also
along with peel, used to prepare jams, jellies and marmalades.
Owing to the ever increasing pressure from population explosion,
the need has arisen to improve the crop to meet the demands which
have a direct relation with galloping population of the global
world of 21st century. In this research, I have been searching for
an efficient procedure for callus induction, regenerative ability
from different explants in Citrus reticulata Blanco, in order to
provide a basis for genetic improvement. I have studied the effects
of different growth regulators on callus initiation from different
explants and shoot and root development from calli.
The complexity of embedded systems is exploding into two
interrelated but independently growing directions: architectures
complexity/heterogeneity and applications complexity. On the other
hand, time- to-market and design productivity factors are
constantly shrinking. Consequently, the gap between system
complexity and design productivity is constantly increasing. To
reduce this gap, System Level Design (SLD) has shown a lot of
potential. However, it still involves a substantial number of
design challenges. For example, complex applications should be
analyzed at higher abstraction level without any architecture
directives to provide application-architecture mapping guidelines.
Fast performance estimation techniques at cycle-accurate level are
required to estimate the software performance on the target
architecture. Similarly, the performance analysis of parallel
execution on heterogeneous architectures without performing HW/SW
co-simulation is an increasingly challenging problem. This book
explores the holistic view of SLD to ensure an optimal and rapid
design of embedded systems.
Swarm intelligence algorithms are taking the spotlight in the field
of function optimization. In this book our attention centers on a
new framework inspired from the food foraging behavior of honey
bees. Utilizing the Particle Swarm Optimization (PSO) algorithm
within this framework we have developed a novel algorithm called
Honey Bee Foraging Particle Swarm Optimization (HBF-PSO). The
HBF-PSO algorithm and its variants are suitable for solving
multimodal and dynamic optimization problems. We focus on the
niching and speciation capabilities of these algorithms which allow
them to locate and track multiple peaks in multimodal and dynamic
environments. The HBF-PSO algorithm performs a collective foraging
for fitness in promising neighborhoods in combination with
individual scouting searches in other areas. The strength of the
algorithm lies in its continuous monitoring of the whole scouting
and foraging process with dynamic relocation of the bees
(solution/particles) if more promising regions are found. Those
looking for a novel approach to function optimization utilizing the
food foraging behavior of honey bees can benefit from the
information presented in this book.
Employee turnover is an important flow of Human Resource System
that effects organization. An integrated employee retention model
from retention and performance perspective have been proposed and
tested. The broader theoretical framework of retention couples the
traditional napproach with contemporary thinking. A cross-sectional
survey based study is designed to test the integrated model.
Structural equation modeling analysis supports the integrated
perspective.
