in this article using comparative multi-purpose algorithm of pso, optimum capacity of new resources and their spinning storage is defined. spinning reserve requirements and optimized to maximize profit per unit is determined according to uncertainty. in fact by increasing the level of cost reservation, power supply increases but penalty of blackout decreases. in this paper in has been tried to ...

The distinction between the different causes of blackouts is an important and challenging clinical task. Given that treatment is very diagnosis-specific, therapeutic success depends entirely on the correct categorisation of the problem. However, despite impressive technological advances in brain imaging and improved access to tests such as video-EEG monitoring and tilt-table testing, the act of...

Power had not yet been fully restored following the recent blackout that some were already clamoring that increasing transmission capacity is the best way to avoid a repetition of these events. Others were laying the blame squarely on the deregulation of the electricity supply industry. Should the United States embark on a massive investment program? Should deregulation be abandoned on the grou...

Abstract This study aims to determine the effect of x-ray radiation resulting from solar flares in high-frequency radio wave communications through ionosphere and blackout events that occur over Iraq, located within (38,28) latitude, (38,49) longitude. Using X-ray data during strong X absorption across D for 10 years 2012 2021. The concluded there were 43 x-flare, most which high activity. All ...
