Note on small singular values of sequences of matrices
(Amer Inst Physics, 2014)
In this paper, some sequences of matrices for matrix pencils are considered. Properties of small singular values of these matrices are investigated. Estimates for singular values are obtained. The result of computer ...
Well-posedness of a fourth order of accuracy difference scheme for the Neumann type overdetermined elliptic problem

In the present paper, inverse elliptic problem with Neumann type overdetermination is discussed. A fourth order of accuracy difference scheme for the solution of this identification problem is presented. Stability, almost ...
Finite Difference Approximations of First Order Derivatives of Complex-valued Functions
(Amer Inst Physics, 2018)
In this study, we generalize the well-known finite difference method to compute derivatives of a real-valued function to approximate complex derivatives w(z) and w((z) over bar) for complex-valued function w. Exploring ...
Approximation of the inverse elliptic problem with mixed boundary value conditions
(Amer Inst Physics, 2014)
The inverse problem for the multidimensional elliptic equation with Neumann-Dirichlet conditions are presented. For the approximate solution of this inverse problem the first and second order of accuracy in t and in space ...
The Determination of the Pulse Pile-up Reject (PUR) Counting for X and Gamma Ray Spectrometry
(Amer Inst Physics, 2017)
The collection the charged particles produced by the incident radiation on a detector requires a time interval. If this time interval is not sufficiently short compared with the peaking time of the amplifier, a loss in the ...

Three-dimensional modeling of women's talus bone
(International Multidisciplinary Scientific Geoconference, 2013)
In this study, semi-automatic region-based digital image processing techniques were used to create 3-dimensional (3D) virtual model of talus bone. 5 ballerinas and 5 sedentary women have voluntarily been involved in to the ...
