Regularization of the Solution of a Cauchy Problem for a Hyperbolic Equation
Autor: T. V. Bugueva, V. A. Dedok, V. G. Romanov
Publikováno v: Journal of Applied and Industrial Mathematics. 15:118-128
Given a hyperbolic equation with variable coefficients, we construct a regularizing algorithm to solve the problem of continuation of the wave field from the boundary of the half-plane inside it. We introduce some $$N$$ -approximate solutions and est

A numerical method of determining permittivity from the modulus of the electric intensity vector of an electromagnetic field
Autor: V. G. Romanov, V. A. Dedok, A. L. Karchevsky
Publikováno v: Sibirskii zhurnal industrial'noi matematiki. 22:48-58
The system of equations of electrodynamics is considered for a nonmagnetic nonconducting medium. For this system, the problem is under study of determining the permittivity e from the given modulus of the electric intensity vector of the electromagne

Regularization of the Solution of the Cauchy Problem: The Quasi-Reversibility Method
Autor: T. V. Bugueva, V. A. Dedok, V. G. Romanov
Publikováno v: Journal of Applied and Industrial Mathematics. 12:716-728
Some regularization algorithm is proposed related to the problem of continuation of the wave field from the planar boundary into the half-plane. We consider a hyperbolic equation whose main part coincideswith the wave operator, whereas the lowest ter

Reconstruction of Permittivity from the Modulus of a Scattered Electric Field
Autor: V. A. Dedok, A. L. Karchevsky
Publikováno v: Journal of Applied and Industrial Mathematics. 12:470-478
We present a numerical algorithm for determining the inhomogeneities of permittivity from the strength modulus of a scattered electric field. The algorithm was tested on simulated noisy data and revealed its practical operability.

Inverse problems of anomalous diffusion theory: An artificial neural network approach
Autor: A. N. Bondarenko, T. V. Bugueva, V. A. Dedok
Publikováno v: Journal of Applied and Industrial Mathematics. 10:311-321
The results are presented of computer simulation of the operation of a three-layer perceptron trained for solving inverse problems of anomalous diffusion theory. Several types of inverse problems are considered, including the problem of determining t

An efficiency estimate for a hierarchical reconstruction method in the problem of reconstructing the locations of discrete scattering centers from a set of projections
Autor: V. A. Dedok, L. A. Oinking, M. P. Tokarev, A. N. Bondarenko
Publikováno v: Journal of Applied and Industrial Mathematics. 7:335-343
Under consideration is the problem of determining a maximal set for a family of points from a restricted collection of their two-dimensional projections. This problem arises naturally in the applications of physical hydroaerodynamics to optical diagn
