  • This paper presents the application of anAutomatic Phase Balancing Device (APBD) to reduce current unbalance in low voltage distribution networks. The proposed algorithm allowsus to calculate the unbalanced level and to conduct the automatic phase balancing device during load variations. This device was then applied to a low voltage feeder of Cau Giay district (Viet Nam). Results show that the unbalanced current is always maintained lessthan 15 %.

  • This paper investigates a Distributed Generators (DG) connected to distribution networks offering multiple benefits for grids and environments in the case of renewable sources used. Nevertheless, this task requires an appropriate planning and control strategy, if not several drawbacks can issue, including voltage rise problems and increased power losses. To overcome such disadvantages, this paper proposes a coordinated voltage control CVC method for distribution networks with multiple distributed generators.

  • For campus networks, Cisco recommends a hierarchical network design that distributes networking function at each layer through a layered organization. The hierarchical model enables the design of a modular topology using “building blocks” that are scalable and allow the network to meet evolving business needs. The hierarchical model is based on a modular design, which is easy to scale, understand, and troubleshoot because it follows a deterministic traffic pattern. The principle advantages of the hierarchical model are:...

  • Many services running on modern digital telecommunications networks require accurate synchronization for correct operation. For example, if switches do not operate with the same clock rates, then slips will occur and degrade performance. Telecommunication networks rely on the use of highly accurate primary reference clocks which are distributed network wide using synchronization links and synchronization supply units.

  • In the recent years the electrical power utilities are undergoing rapid restructuring process worldwide. Indeed, with deregulation, advancement in technologies and concern about the environmental impacts, competition is particularly fostered in the generation side thus allowing increased interconnection of generating units to the utility networks. These generating sources are called as distributed generators (DG) and defined as the plant which is directly connected to distribution network and is not centrally planned and dispatched.

  • Th e prime objective for writing the fi rst edition of this book was to provide an up-to-date text at a reasonable cost. We also felt that there was a signifi cant gap in the literature for a book that off ered a broad strategic framework as well as a clear and straightforward description of the basic functions and elements related to logistics and distribution. In the second edition of the book, published in 2000, we provided a signifi cant revision of the original text.

  • Telecommunications is now the fastest changing part of the IT industry, encompassing vast disciplines from distributed systems to real-time applications. I have had the pleasure of being involved in what I believe is the most exciting time in its history. It wasn’t always this way, as telecommunications started out as a novelty: ‘‘An amazing invention, but who would want to use one?’’ – US President Rutherford B. Hayes after making a telephone call from Washington D.C. to Philadelphia. Interestingly however, in 1879, the first telephone was installed in the White House.

  • The following 3 questions all refer to the scenario below: The company Certkiller manufactures and imports fasteners like bolts and nuts. The company's network consists of a main campus composed of three separate building that are less than 150 meters apart, connected with Category 5e copper wiring. Network access as well as distribution takes place by means of 100 Mbps hubs, and the core is a 100 Mbps Layer-2 switch. The company has been in existence for 8 years and thus development in the network resulted in a series of steps that involved minimal planning.

  • Since the introduction of the personal computer in the early 1970s, businesses have found more uses and applications for technology in the workplace. With the introduction of local- area networks, file sharing, and print sharing in the 1980s, it became obvious that distributed computing was no longer a passing fad. By the 1990s, computers became less expensive, and innovations such as the Internet allowed everyone to connect to computer services worldwide. Computing services have become large and distributed.

  • Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed over a wide geographical area, indoor or outdoor
