solution of security constrained unit commitment problem by a new multi-objective optimization method

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...

Photosynthetic Characteristics and Antioxidative Responses in Three Species of Crassulaceae Following Drought Stress

Photosynthetic characteristics and induction of crassulacean acid metabolism (CAM) by drought stress were investigated in Sedum album, Sedum stoloniferum and Rosularia elymaitica from Crassulaceae. Titratable acidity, malate content, phosphoenolpyruvate carboxylase (PEPC) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. Results showed t...

Increasing the Upstream Capacity of Passive Optical Networks by Pulse Amplitude Multiplexing

Pulse Amplitude Multiplexing (PAMx) is proposed to increase the upstream throughput of Passive Optical Networks (PONs). PAMx requires the change of the electronics at the Optical Network Units (ONUs) and Optical Line Terminal (OLT), but not of the optical or distribution network components. This scheme allows the simultaneous transmission of data from multiple ONUs whose power levels have been ...

Creatine kinase MB measured by fluorometric enzyme immunoassay and immunochemiluminescence.

Creatine kinase MB (CK-MB) was measured in serum by a fluorometric enzyme immunoassay on the Stratus analyzer and by an immunochemiluminometric assay using the Ciba Corning Magic Lite System. Both methods were standardized against purified CK-MB, with Stratus underestimating by 20 percent and Magic Lite overestimating by 28 percent. The assays proved sensitive and linear; however, at a CK-MB co...
