Soon after Samuel Morse’s telegraphing device led to a deployed electri-
cal telecommunications system in 1843, waiting lines began to form by those
wanting to use the system. At this writing queueing is still a significant factor in
designing and operating communications services, whether they are ...
It is more than a decade since GSM was first commercially available. After some unexpected delay, it
seems that finally UMTS is here to stay as a 3G system standardised by 3GPP, at least for another ten
years. UMTS will enable multi-service, multi-rate and flexible IP native-based mobile technologie ...
When 3GPP started standardizing the IMS a few years ago, most analysts expected the
number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were
ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly
after that). While those predictions ...
The first practical examples of mobile communications were used in many countries like
the USA, the UK and Germany in military services, and played a significant role in the
First World War to transfer important information from the front to headquarters to take
further actions. Good and secure wire ...
n the first part of this book, we give an introduction to the basic applications of wireless com-
munications, as well as the technical problems inherent in this communication paradigm. After a
brief history of wireless, Chapter 1 describes the different types of wireless services, and works
out the ...
It has been over a decade since the Chinese publication of Line Loss in Electric Power Systems. To keep pace
with technological developments, I started a revision as early as 2002, following the main principles that the
theoretical framework and characteristics of the first edition should be retaine ...
This book is based on a Ph.D. research that has been conducted at the Delft
University of Technology in the Netherlands in collaboration with Dutch Electricity
& Gas Distribution Network Operator, Stedin. This book was written as a result of
wider interest that was shown by different industry groups ...
With the continued growth in the world's population, there is a need to ensure availability of
enough food to feed everyone. Advances in science and technology have helped not only to
increase food production, but also to reduce food wastage. However, the latter has the
potential to be improved to a ...
RFID (radio-frequency identification) is the use of a wireless non-contact system
that uses radio-frequencyelectromagnetic fields to transfer datafrom a tag attached
to an object, for the purposes of automatic identification and tracking [38]. The
basic technologies for RFID have been around for a l ...
There exist two essentially different approaches to the study of dynamical systems, based on
the following distinction:
time-continuous nonlinear differential equations ⇋ time-discrete maps
One approach starts from time-continuous differential equations and leads to time-discrete
maps, which are ob ...
