The Johns Hopkins university will take part in a city-wide blackout from 9:45 till A0:00tonight. Headed by Chief Warden. .Dr...Sidney Painter, wardens, assistant wardens, and first aid representatives for this and other blackouts have been appointed by a faculty committee on Campus Protection, which has been functioning since December 15. In addition, student volunteers in the dormitories are t...
Some criminal suspects claim to have had an alcohol-induced blackout during crimes they have committed. Are alcoholic blackouts a frequently occurring phenomenon, or are they merely used as an excuse to minimize responsibility? Frequency and type of blackout were surveyed retrospectively in two healthy samples (n = 256 and n = 100). Also, a comparison of blood alcohol concentrations was made be...
We propose BlackOut, an approximation algorithm to efficiently train massive recurrent neural network language models (RNNLMs) with million word vocabularies. BlackOut is motivated by using a discriminative loss, and we describe a weighted sampling strategy which significantly reduces computation while improving stability, sample efficiency, and rate of convergence. One way to understand BlackO...
Abstract: Blackouts are among the main threats to the security of electric power systems. Cascading failures are known as the most important agent for creating blackouts. Transmission lines are the basic equipment of power networks that their outage can make subsequent cascading outages. In this paper, based on the application of decision tree a new approach is proposed for online identificatio...
The phenomenon of wet dust in Khuzestan province in February 2016 affected the provincechr('39')s electricity network and caused a widespread blackout. Following the power outage, other infrastructure in the province also suffered, the blackout crisis stimulated widespread social reactions. Accordingly, in this article, using the mixed method methodology, the dimensions and social consequences ...
With the advent of advanced technology in smart grid, the implementation of renewable energy in a stressed and complicated power system operation, aggravated by a competitive electricity market and critical system contingencies, this will inflict higher probabilities of the occurrence of a severe dynamic power system blackout. This paper presents the proposed stochastic event tree technique use...
LPWANs are a class of technologies that have very low power consumption and high range of communication. Along with its various advantages, these technologies also have many limitations, such as low bandwidth, connectionless transmission and low processing power, which has challenged encryption methods in this technologies. One of the most important of these challenges is encryption. The very s...
In order to estimate and evaluate the blackout consequence in distribution network, a comprehensive evaluation index system including seven indexes was built, in which the blackouts loss for both users and power companies are fully considered. A comprehensive evaluation model based on AHP and improved grey clustering decision model was provided to evaluate the blackout consequence of different ...
During extremely hot summer days, air conditioning systems are known as major electricity consumers in residential, commercial and industrial sectors. Moreover, high energy requirement of multiple-chiller plants may cause an interconnected power grid be faced with annual on-peak electrical demand, load-generation mismatch, voltage collapse and catastrophic wide area blackout. Therefore, this pa...
