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...

A Multi - Method Approach to Performing

Software costs are rising, as are problems with software quality and delivering software on schedule and within the development budget; as a consequence more researchers are arguing that substantial empirical investigation is necessary to develop techniques and methods to address these problems. This paper introduces a multi-method approach to conducting empirical research and discusses the ben...

A quick method of performing the Paul-Bunnell test.

(4) In the remaining tubes of each row is placed 0.5 ml. of 0.85% sodium chloride. (5) To the first tube of each row 0.1 ml. of serum is added and mixed thoroughly. (6) Then 0.5 ml. of the diluted serum is carried over into tube 2 and so on until tube 10, the last 0.5 ml. being discarded. (7) To each tube 0.5 ml. of washed fresh sheep cells is added, thus giving a final serum dilution of 1:20 u...
