abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
این پایان نامه با کاربرد داده های نادقیق در تحلیل پوششی داده ها (dea) سروکار دارد. داده های نادقیق بدین معنی است که بعضی داده ها فقط در دامنه ای که مقادیر موردنظر درون کران های تعیین شده قرار دارند مشخص شده اند در حالی که داده های دیگر فقط برحسب رابطه های ترتیبی مشخص شده اند. تحلیل پوششی داده های نادقیق (idea) اندازه گیری کارایی نسبی واحدهای تصمیم گیرنده برای داده های ورودی و یا خروجی که نادقی...
The basic idea of traditional density estimation is to model the overall point density analytically as the sum of influence functions of the data points. However, traditional density estimation techniques only consider the location of a point. Supervised density estimation techniques, on the other hand, additionally consider a variable of interest that is associated with a point. Density in sup...
Functionally graded materials (FGM) in the form of layered structure consisting of yttria stabilized zirconia (8 mol% Y2O3) and nickel were fabricated by spark plasma sintering procedure. The relative density, linear shrinkage and Vickers hardness of each layer of graded materials were measured. The microstructure and the composition of these components were studied. The results obtained show t...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
