چکیده
Abstract The tribological performances of perfluoroalkylpolyethers (PFPE) with graphene (Gr), WS 2 , and the mixture Gr (Gr + ) before after ultraviolet (UV), atomic oxygen (AO), proton (Pr) irradiations were investigated. composition structure PFPE, Gr, also analyzed to understand effects irradiation on behaviors PFPE additives. results indicated that serious deterioration degradation took place was transformed amorphous carbon Pr irradiation, surface oxidation occurred under AO Pr. Moreover, compared additized addition exhibited excellent friction wear reduction UV irradiations. Graphical

Synthesis of Ultrathin WS2 Nanosheets and Their Tribological Properties as Lubricant Additives
In this paper, ultrathin WS2 nanosheets with thickness of about 5 nm were successfully prepared by a facile solid phase reaction method. The as-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). On the basis of experimental results obtained under different reaction durations, a possible formation mec...

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
