In this paper a new methodology for determining the optimal level of automation in microgrids is proposed. In traditional distribution networks, automation is referred to the management of the fault in a more efficiently manner especially in medium voltage (MV) distribution network in order to improve the network reliability indices by reduction of average outage duration per consumer and meanw...

To help people who have lost their voice following total laryngectomy, we present a speech restoration system that produces audible speech from articulator movement. The speech articulators are monitored by sensing changes in magnetic field caused by movements of small magnets attached to the lips and tongue. Then, articulator movement is mapped to a sequence of speech parameter vectors using a...

Abstract Forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. This paper studies load consumption modeling in Hamedan city province distribution network by applying ESN neural network. Weather forecasting data such as minimum day temperature, average day temp...

We propose a refinement to existing methods for span-restorable mesh capacity design to increase the capacity efficiency on sparse facility graphs. The resultant designs comprise a special class of restorable network that is intermediate between pure span restoration and path restoration. Most of the efficiency of path restoration is achieved by targeting chain sub-networks that ordinarily requ...

one of the consequences of poor management and operation of irrigation systems, poor water delivery and distribution channels and divisions and consequently improper distribution of water level downstream. the study of simulation and performance evaluation software using hydrodynamic sobek varamin irrigation is done. in order to evaluate the network performance and compare the results of simula...

In this article, a multi-objective function for placement of Distributed Generation (DG) and capacitors with thetap setting of Under Load Tap Changer (ULTC) Transformer is introduced. Most of the recent articles have paidless attention to DG, capacitor placement and ULTC effects in the distribution network simultaneously. Insimulations, a comparison between different modes was carried out with,...

This paper deals with the fundamental problem of estimating the distribution function (df) of the duration of the longest path in the stochastic activity network such as PERT network. First a technique is introduced to reduce variance in Conditional Monte Carlo Sampling (CMCS). Second, based on this technique a new procedure is developed for CMCS. Third, a combined approach of simulation and ap...

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...
