Measurement of Isotopic Ratio by Balance Method

Measurement of Mixture Mass Ratio by Acoustic Emission Method

The article deals with solid particle flow measurement by acoustic emission method (AE). The particle, that impacts a waveguide, generates impulse AE. AE signal, measured by a piezoelectric wide-band sensor mounted at the end of the waveguide, carries information about parameters of impacting particles (specific mass, velocity, dimensions). The article is a follow-up to formerly performed measu...

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 Survey on Current Methods of Carpal Height Ratio Measurement and Suggestion of a New Method

Background & Aims: Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram' Methods: This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiogr...

Rapid measurement of soil water by gravimetric method

Quantitative Determination of Isotopic Abundance Ratio of

O-Toluic acid (OTA) and m-toluic acid (MTA) are two isomers of toluic acid that act as an important organic intermediates, mostly used in medicines and pesticides. The aim of the study was to evaluate the impact of biofield energy treatment on isotopic abundance ratios of 2 H/ 1 H, 13 C/ 1 2C, (PM+1)/PM and 18 O/ 16 O, (PM+2)/PM, in toluic acid isomers using gas chromatography-mass spectrometry...
