Development of Recovery Methods for Spilled Oil under Ice Floes

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

流氷下に流出した原油の回収方法に関する基礎的研究 Development of Recovery Methods for Spilled Oil under Ice

Development of oil and natural gas deposits off Sakhalin's northern coast on the Sea of Okhotsk are currently under way. Should an accident involving a spill of crude oil or other effluents occur during the development of the oil and natural gas deposits that is currently under way off the eastern coast of northern Sakhalin, it can be expected to have an impact on the environment and economy of...

ψ-s correlation and dynamic time warping: two methods for tracking ice floes in SAR images

In recent years, there has been an interest in automating the process of producing maps of the motion of ice floes from SAR images acquired a few days apart. A common approach is to correlate raw pixel values in order to find corresponding features in two images. The problem with this approach is that the search space is often prohibitive when ice floes rotate, as they frequently do. We present...

Detection and Tracking of Oil Under Ice

degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
