The energy efficiency of network hardware has become a topic of considerable interest in recent years, motivated by the explosive growth of information and communication technology (ICT), and the ever increasing energy costs as well as the need to reduce Greenhouse Gas (GHG) emissions globally. One approach to saving energy in routers is to use dynamic adaptation, and this paper describes the development...
Recently, energy expenditures of the Internet have increased dramatically, raising energy issue of routers an urgent problem in relative research areas. In fact, much device surplus and redundancy are introduced during network planning for rarely appeared traffic peak hours and device failures, wasting energy most of the time. In this work, an energy-aware architecture is proposed for routers, which...
To achieve active control and active management of distribution network, flexible interconnect devices (FID) based on power electronics are proposed to optimize the power flow. This kind of device can be a good supplement to conventional control means due to its ability to regulate the power flow. This paper addresses network reconfiguration with the application of FID for improved flexibility in...
Back-to-back capacitor bank switching is a specific operation which combines an inrush current during a making process and a power frequency current interruption followed by a subsequent DC recovery voltage during a breaking process. For a vacuum interrupter (VI), the dielectric strength is mainly depends on the condition of the contact surfaces which may be damaged by a pre-arcing of the inrush currents...
So far, achieving high data rate has been the primary focus of research in wireless communication systems, without much consideration of energy efficiency. However, many of communication technologies significantly increase system complexity and energy consumption. In addition to the environmental problems that the governments restrict the greenhouse gases and pollution, energy costs also contribute...
This paper deals with the synchronization of MOPA KrF laser system. In this study, the delay and jitter of all parts of MOPA system has been carried out. Specially, delay and jitter of the switches has been tested under various under-voltage and laser energy, the optimization of the switches operating range is obtained. The results were shown that the jitter of switches is less than 3ns and total...
