Driving single nanoparticles like DNA and proteins by the electrophoretic force through a nanopore in the presence of an electric field produces an ionic current, which passes from the nanopore. The current blockage due to the nanoparticle translocation makes an observable change in the ionic current, which is useful for the study of bio molecules. Many efforts are made to perceive the electro ...
پنل های خورشییدی دارای مشیه ه جریان -ولتاژ غیر خطی بوده و تنها در یک نقطه کار خاص، حداکثر توان را تولید می کنند. این نقطه بهینه توان با تغییر دما و شیدت نور تغییر می کند. روش های مهتلفی برای ردیابی نقطه حداکثر توان به صورت free model و based model معرفی شده است. این تحقیق روش جدیدی جهت بهبود عملکرد ردیابی نقطه حداکثر توان پنل های خورشیدی جدا از شبکه ارائه می دهد و الگوریتم روش پیشینهادی از دو...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Abstract The crawling process of snakes is known to have fascinating tribological phenomena, whereas investigations on their frictional properties depending patterned cuticles are insufficient. In this study, we designed and fabricated biomimetic microstructures inspired by the geometric microunits Achalinus spinalis cuticle using polyurethane acrylate (PUA) material performed its analysis. mic...
