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...
طراحی و شبیه سازی یک شیفت دهنده فاز میکرو الکترومکانیکی 6 بیتی در باند x مورد بررسی قرار گرفته است. در طراحی این شیفت دهنده ساختار به نسبت جدیدی را با ادغام دو ساختار dmtl و switched-line ارایه داده¬ایم. با توجه به نتایج شبیه سازی، میانگین return loss و insertion loss برای تمامی 64 حالت شیفت فاز در فرکانس ghz 7/9 به ترتیب برابر db 22- و db 06/0- است. همچنین در این فرکانس مقدار موثر خطای فاز برا...
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...
In this research, we propose a bi-objective model for the economic-statistical design of the X-bar and S control charts. The model minimizes out-of-control average time to signal as well as minimizing mean hourly loss-cost where it incorporates the Taguchi loss function. Statistical constraint is considered in the model to achieve desired in-control time to signal. A non-dominated sort...
in this paper, we introduce non-interest profit/loss sharing (pls) banks into a three-period overlapping generations model. two types, (low- and high quality) investments are assumed and capital accumulation and level of output in the steady state is considered. then, administrative rationing is introduced to the model. it is shown that the level of capital accumulation and output in equilibriu...
