electricity price predictions have become a major discussion on competitive market under deregulated power system. but, the exclusive characteristics of electricity price such as non-linearity, non-stationary and time-varying volatility structure present several challenges for this task. in this paper, a new forecast strategy based on the iterative neural network is proposed for day-ahead price...
this paper presents a new coding method for image compression based on jpeg2000 and contourlet transform. jpeg2000 standard is a common standard that uses discrete wavelet transform (dwt) in the compression process. the main problems of dwt are failure to detect curved edges in image and its shortage representation of the ridge and furrow patterns which cause deficiency and block artifacts rema...
در گذشته تمرکز مطالعات دگرآسیبی بیشتر بر روی ارزیابی فعالیت سمیتی بقایای گیاهی و عصاره های آنها صورت می گرفت اما در سال های اخیر از طریق تاسیس و توسعه موسسه های علمی در سرتاسر جهان، پیشرفت های تکنیکی در زمینه این تحقیقات صورت گرفته و دانش دگرآسیبی طی دو دهه اخیر به علت ابداع روش های پیشرفته و همچنین همکاری بین دانشمندان و دستیابی به زیست آزمونهای مناسب، پیشرفت چشمگیری داشته است. از جمله روش های...
this paper proposes a new method for transmission loss allocation. the share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. then, it is applied to the total network transmission lines. in the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introduced...
