The Basolateral Amygdala (BLA) has modulatory effects on working and reference memory. The aim of this study was the evaluation of effects of dopaminergic system in the BLA of rats on working and reference memory behaviors. The number of working and reference errors and time spent in the arms by rats were measured in the radial arm maze according to DSWS protocol. The animals were cannulated in...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
study about political attitude and gender differences seems necessary, because of essential role of the political attitude in political behavior, and importance of gender differences for researchers in the field of women's studies. considering to this scientific necessity, this study investigates the role of university reference groups in college students' political attitudes accordin...

یکی از زمینه¬های تحقیقاتی با اهمیت در حوزه پردازش تصاویر، ارزیابی کیفیت تصویر می¬باشد. امکان کاهش کیفیت تصاویر هنگام انتقال، پردازش و فشرده¬سازی وجود دارد. تاکنون نظر انسان به عنوان قابل اعتماد¬ترین روش برای ارزیابی کیفیت تصویرمی باشد اما این روش علاوه بر محدودیت¬هایی که دارد بسیار وقت¬گیر و هزینه بر می¬باشد. هدف الگوریتم¬های ارزیابی کیفیت تصویر، طراحی مدل محاسباتی است که مانند انسان، قادر به پ...
اندازه¬گیری کیفیت تصاویر برای طراحی سیستم¬های پردازش تصویر که به طور بالقوه قادر به مقیاس¬بندی کیفیت بصری می¬باشند، بسیار با اهمیت است. برخی از اندازه¬گیری¬ها به توسعه¬دهندگان اجازه¬ی بهینه¬سازی طراحی¬هایشان برای ارائه¬ی بهترین کیفیتبا کمترین هزینه را می¬دهد. این پایان¬نامه در ارتباط با الگوریتم¬های خودکاری است که کیفیت تصاویر دیجیتال را بدون در دسترس داشتن هیچ¬¬گونه اطلاعاتی در مورد تصویر اصلی...
