a type of coaxial cable used to connect nodes on an Ethernet network. The10 refers to the transfer rate used on standard Ethernet, 10 megabits per second. The base means that the network uses baseband communication rather than broadband communications,and the 2 stands for the maximumlength of cable segment, 185 meters (almost 200). This type of cable is also called “thin”Ethernet, because it is a smaller diameter cablethan the 10base5 cables.
Telecommunications is one of the fastest growing business sectors of modern
information technologies. A couple of decades ago, to have a basic understanding
of telecommunications, it was enough to know how the telephone
network operated. Today, the field of telecommunications encompasses a
vast variety of modern technologies and services. Some services, such as
the fixed telephone service in developed countries, have become mature,
and some have been exploding (e.g., cellular mobile communications and
Topology Control in Wireless Ad Hoc and Sensor Networks makes the case for topology control and provides an exhaustive coverage of TC techniques in wireless ad hoc and sensor networks, considering both stationary networks, to which most of the existing solutions are tailored, and mobile networks. The author introduces a new taxonomy of topology control and gives a full explication of the applications and challenges of this important topic.
Power engineering is the oldest and most traditional of the various areas within
electrical engineering, yet no other facet of modern technology is currently undergoing
a more dramatic revolution in technology or business structure. Perhaps
the most fundamental change taking place in the electric utility industry is the
move toward a quantitative basis for the management of service reliability.
The growing interest in the application of artificial intelligence (AI) techniques to
power system engineering has introduced the potentials of using this state-of-the-art
technology. AI techniques, unlike strict mathematical methods, have the apparent
ability to adapt to nonlinearities and discontinuities commonly found in power
systems. The best-known algorithms in this class include evolution programming,
genetic algorithms, simulated annealing, tabu search, and neural networks.
In the last three decades many papers on these applications have been published.
Specifies the electrical, mechanical, procedural, and functional requirements for activating, maintaining, and deactivating the physical link between end systems. Examples of physical link characteristics include voltage levels, data rates, maximum transmission distances, and physical connectors.
The use of neural networks is permeating every area of signal processing. They can provide powerful means for solving many problems, especially in nonlinear, real-time, adaptive, and blind signal processing. The Handbook of Neural Network Signal Processing brings together applications that were previously scattered among various publications to provide an up-to-date, detailed treatment of the subject from an engineering point of view.
A comprehensive introduction to the most popular class of neural network, the multilayer perceptron, showing how it can be used for system identification and control. The book provides readers with a sufficient theoretical background to understand the characteristics of different methods, and to be aware of the pit-falls so as to make the correct decisions in all situations. This is a very application-oriented text that gives detailed and pragmatic recommendations to guide users through the plethora of methods suggested in the literature.
There is an upward trend that human activities involve more electric power nowadays
and for years to come. And we will soon be facing shortage of electricity supply if we
rely solely on non-renewable power generation from fossil fuels such as coals.
Renewable energy generation has proven effective in meeting the demand.
Interface converter, for converting RS-232 to RS-422 and RS-485, with electrical isolation, 2 channels
Bidirectional, wireless, 2400 MHz transmission system (European version), consisting of 2 transceivers (transmitter and receiver) and two antennas with connecting cable
Fieldline Modular Wireless IO set, consisting of: Wireless IO base station for one Wireless IO terminal and Wireless IO device, 8 digital inputs, 8 digital outputs
This book covers fundamental aspects of electric circuits that form the core of many engineering disciplines. In particular, basic circuit elements and their characteristics are presented when connected in an electric network. In addition, techniques to analyse and solve electric circuits are explained in a simple manner and examples are shown to demonstrate each strategy. DC as well as AC circuit analysis is provided with a brief account of filters in the end.
Anyone looking for information about power outages in Germany needs to consult the “Availability Statistics” published by the association of German electricity network operators (VDN) within the German Energy and Water Association (BDEW). This is where the power industry keeps a tally of “incidents”, by which it generally means mains power failures.
Telecommunication networks are not static.
In order to support evolving service offerings,
they must evolve in size, shape and complexity.
Initial network design should consider the
need for expansion and growth. Proper design
plays a critical role in determining whether a
network is an effective revenue generator, or
whether it loses profitability through excess
labour costs and missed service opportunities.
FlexDSX™ cross-connect products provide
the necessary network flexibility.
Since then Dr. Hans Berger discovered the electrical properties of the brain, it was considered
ability to communicate outside personswith device only through the use of the brain
wave (Vidal, 1973).
Brain computer interface technology is aimed at communicating with users outside
computer equipment through electroencephalographic signals as the command source
(Wolpaw, JR, et al, 2000), (Birbaumer, N, et al, 2000).
This document provides an overview of wireless networking technologies and wireless handheld devices
most commonly used in an office environment and with today’s mobile workforce. This document seeks
to assist agencies in reducing the risks associated with 802.11 wireless local area networks (LAN),
Bluetooth wireless networks, and handheld devices.
ADC’s Extend™ Optical/Electrical Line Extender transports support E3/DS3/STS-1 signals over
