VINYL ETHER: A NEW METHOD OF ADMINISTRATION

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...

Thermal dissociation of ethylene glycol vinyl ether.

The pyrolysis of ethylene glycol vinyl ether (EGVE), an initial product of 1,4-dioxane dissociation, was examined in a diaphragmless shock tube (DFST) using laser schlieren densitometry (LS) at 57 ± 2 and 122 ± 3 Torr over 1200-1800 K. DFST/time-of-flight mass spectrometry experiments were also performed to identify reaction products. EGVE was found to dissociate via two channels: (1) a molecul...

The Administration of Ether

The administration of ether.

Ether vapour has stood the test of one hundred years this year and it still holds first place as the safest anaesthetic agent. It has only two indisputable drawbacks in comparison with all other agents; these are inflammability and the dislike most people have for its smell. All other disadvantages so often lauded are by no means proven. It is not suggested for a moment that ether is the first ...

Preparation of vinyl chloride – vinyl ether copolymers via partial etherification from PVC

The chemical modifications of poly (vinyl chloride) with aliphatic and aromatic alcohols compounds have been investigated at room temperature and atmospheric pressure, catalysed by a new green basic catalyst, the Maghnite-K. The presence of ether groups in the products is proven by infra red spectroscopy (IR) as well as by nuclear magnetic resonance spectroscopy (1H NMR), and characterized by i...
