در این تحقیق، لایه های نازک دوتایی in2o3:s و in2s3:sn به روش اسپری پایرولیزیز بر روی بستر های شیشه-ای تهیه شده اند و تاثیر تغییرتراکم گوگرد و قلع بر روی خواص ساختاری، الکتریکی، اپتیکی،ترموالکتریکی و فوتورسانایی این لایه ها بررسی شد. برای تهیه لایه نازک in2o3:s میزان ناخالصی سولفور با نسبت اتمی [s]/[in]= 0-0.2-…-1.5 در محلول اولیه تغییر داده شد. نتایج xrd نشان می دهد که در تراکم پایین سولفور، فا...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Data envelopment analysis (DEA) is a nonparametric approach to evaluate theefficiency of decision making units (DMU) using mathematical programmingtechniques. Almost, all of the previous researches in stochastic DEA have been usedthe stochastic data when the inputs and outputs are normally distributed. But, thisassumption may not be true in practice. Therefore, using a normal distribution wi...
