in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
the paper presents a mathematical base modeling combined to modified-winding -function-approach (mwfa) for eccentricity fault detection of a round-rotor synchronous machine. for this aim, a 6-pole machine is considered, and the machine inductances are computed by mwfa in healthy and also under eccentricity fault. a numerical discrete-time method has been proposed to machine modeling in voltage-...
The heat transfer process from pellet to coolant is one of the important issues in nuclear reactor. In this regard, the fuel to clad gap and its physical and chemical properties are effective factors on heat transfer in nuclear fuel rod discussion. So, the energy distribution function of electrons with an energy about 0.5 MeV in fuel rod gap in Busherhr’s VVER-1000 nuclear reactor was investiga...
Objective: This study aimed to investigate the role of family function, generation gap and socioeconomic status in addictability of young people. Method: The number of 400 male students from State, Azad and Payam Noor universities was selected through voluntary sampling. Then, they filled out Addiction Susceptibility Questionnaire, Family Assessment Device, and Generation Gap Scale. Results: Th...
in this paper, by using dynamic stochastic general equilibrium, optimal monetary rule derived for central bank of iran. monetary transmission mechanism of the model includes four equations, aggregate demand, aggregate supply, oil price and taylor rule. we have proved that dynamic structure of aggregate demand relation, regarding monetary inflation in iran, is a function of money growth rate. wi...
این تحقیق به منظور یافتن تاثیر دو نوع task به نام های information gap و opinion gap بر روی نوشتار زبان آموزان برون گرا بوده است. به این منظور گروهی از 110 دانش آموز دبیرستانی به پرسشنامه آیزنک پاسخ دادند که از بین آنها 91 دانش آموز برون گرا انتخاب شد. این 91 نفر قبل از شروع کار برای همگون سازی در آزمون پت شرکت کردند. در نهایت دو گروه که یک گروه شامل 32 دانش آموز با opinion gap taskو یک گروه 30 ...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
In this paper, we introduce and study some new single-valued gap functions for non-differentiable semi-infinite multiobjective optimization problems with locally Lipschitz data. Since one of the fundamental properties of gap function for optimization problems is its abilities in characterizing the solutions of the problem in question, then the essential properties of the newly introduced ...
While technical efficiencies of firms that are estimated with respect to a given frontier are comparable, this is not normally valid the case among firms that operate under different technologies. Such problem arises when comparisons of firms from different regions of country are involved. This study uses the concept of the metafrontier function to investigate regional differences in milk produ...
