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...
Objective: The purpose of this study was to investigate the relationship between cognitive emotion and regulation addiction tendency with the mediating roles of loneliness and early maladaptive schemas among students. Method: The present study was descriptive-correlational and structural equations. The statistical population included all students in master degree in Islamic Azad University of Z...
A key aspect of disease prevention and early detection for improved treatment, across a range of medical disciplines, is the development and implementation of prognostic models. Formulating such models, however, involves a range of practical challenges and associated statistical and epidemiological concerns. Although analytical approaches are generally well described for proper design, model de...
conclusions family history as well as baseline bilirubin, ast and hbv dna levels can predict early virological response. the model provides a better tool for response prediction based on the four prognostic factors. results negative family history of hbv infection (p = 0.000235), baseline higher serum tbil (p = 0.038714) and ast (p = 0.020684) concentrations, and lower level of hbv-dna (p = 0.0...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
