one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...

روش AN-EUL روشی خودکار برای برآورد هم‌زمان عمق، اندیس ساختاری(Structural Index) و مکان منبع‏های مغناطیسی است. اندیس ساختاری شکل کلی منبع را برآورد می‏کند. اساس این روش ترکیب روش‏های سیگنال تحلیلی و واهمامیخت اویلر(Euler Deconvolution) است. در این روش از جای‌گذاری مشتق‏های مرتبه‏ گوناگون معادله اویلر در معادله سیگنال تحلیلی میدان پتانسیل، روابطی کلی برای محاسبه عمق و اندیس ساختاری منبع در محل من...

magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...

the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
