A sensor network consists of many low-cost, low-power, and multifunctional sensor nodes. One of the most important issues in sensor networks is to increase network lifetime, and there have been researches on the problem. In this paper, we propose a routing mechanism to prolong network lifetime, in which each node adjusts its transmission power to send data to its neighbors. We model the energy ...

Power quality monitors (PQM) are required to be installed in a power supply network in order to assess power quality (PQ) disturbances such as voltage sags. However, with few PQMs installation, it is difficult to pinpoint the exact location of voltage sag. This paper proposes a new method for identifying the voltage sag source location by using the artificial neural network (ANN). Radial basis ...

This document defines requirements for standards specifications for Energy Management. The requirements defined in this document are concerned with monitoring functions as well as control functions. Monitoring functions include identifying energy-managed devices and their components, as well as monitoring their Power States, Power Inlets, Power Outlets, actual power, Power Attributes, received ...

  Background : Cement industry has many process units. Basically all of these units can be considered as a source of noise. Since noise pollution is defined based on its offensive hearing effects, the importance of the noise sources depends directly on the number of workers in the unit.   Materials and Methods : An experimental study has been done at Tehran cement factory to recogn...

in distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. in this paper, the hybrid shuffled frog leaping algorithm (hsfla) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. high accuracy and ...
