1. Digital Processing of Two-Dimensional Signals in the Basis of Haar Wavelets Conference: the 19th International Conference. Elmira Nazirova.
Abstract:
This article discusses the use of local systems of basic functions defined on compact carriers. Their effectiveness is shown when solving the problems of discretization of finite signals. Signals can be not only time functions defined at finite intervals, but also functions of arguments of another physical nature, for example, distances along surfaces.


2. Mathematical model and numerical algorithms to analyze gas filtration process in a porous medium. December 2019Journal of Physics Conference Series 1399(5):055036. Elmira Nazirova.
Abstract:
The paper deals with the problem of gas filtration process in a porous medium using a mathematical model of an object; the model is described by a nonlinear partial differential equation and the corresponding boundary and internal conditions. The paper presents the main stages in construction of mathematical model of the process of gas filtration in porous media, taking into account the changes in hydrodynamic parameters of the object of study. To solve the above problem, the following numerical methods have been used: local-one-dimensional schemes and longitudinal-transverse direction schemes. To solve the problem of nonlinear gas filtration in a porous medium, several methods of constructing an iterative process have been checked. To study the responses of the principal parameters of the process, a series of computational experiments on a computer, their analyses and conclusions are given in the paper.
