Sentiment lexicon is very helpful in dimensional sentiment applications. Because of countless Chinese words, developing a method to predict unseen Chinese words is required. The proposed method can handle both words and phrases by using an ADVWeight List for word prediction, which in turn improves our performance at phrase level. The evaluation results demonstrate that our system is effective i...

Novel approach designed in this paper permits the suppression of impulsive noise in multichannel video sequences. It employs the fuzzy logic and vector order statistic methods to detect motion and noise presence during spatial-temporal processing neighbouring video frames, preserving the edges, fine details, as well as colour properties. Numerous simulation results have justified it excellent p...

زمینه و هدف: مدل‌سازی آلاینده‌های زیست محیطی یکی از نیازهای اساسی در زمینه پایش کیفیت هوا محسوب می شود که با بهره‌گیری از نتایج حاصله می‌توان اقدامات پیشگیرانه‌ای جهت بهبود شرایط آتی اتخاذ کرد. ادبیات موجود در زمینه الگوسازی آلاینده‌های زیست محیطی را می توان به دو دسته کلی تقسیم کرد، دسته اول شامل مطالعاتی می‌شود که علاوه بر داده‌های مربوط به آلاینده‌ها با وارد کردن عوامل محیطی از قبیل دمای هوا...

In this research, based on the observed data of Class A pan evaporation and application of non-linear regression (NLR), artificial neural network (ANN), neuro-fuzzy (NF) as well as Stephens-Stewart (SS) methods daily evaporation of Kerman region was evaluated. In the cases of NLR, ANN and NF methods, the input variables were air temperature (T), air pressure, relative humidity (RH), solar radia...

In this paper, a novel rate control algorithm suitable for realtime video encoding is proposed. The proposed algorithm uses mean absolute error (MAE) results of motion estimation (ME) to achieve bitrate control. Neither pre-analysis nor multi-pass encoding is required in our algorithm, which makes realtime hardware implementation possible. A new hardware oriented scene change detection method i...
