the aim of this study preparation of the predicted soil maps by using kriging and inverse distance weighting methods in east rangeland of semnan. sampling was done within each unit of sampling parallel transects and 1 vertical transect with 750m length. soil samples were taken from 0-20 cm in starting and ending points of each transect. there were used kriging and inverse distance weighting met...

Abstract This paper deals with the numerical approximation of biharmonic inverse source problem in an abstract setting which measurement data is finite-dimensional. unified framework particular covers conforming and nonconforming finite element methods (FEMs). The analysed through forward problem. Error estimate for solution derived set-up that applies to Morley FEMs. Since ill-posed, Tikhonov reg...
