The method of chimeric meshes is applied to simulate the propagation of elastic perturbations in media containing porous and fractured inclusions. A model of a linearly elastic isotropic medium is considered, which describes the state of a geological rock. The grid-characteristic method with the third-order accurate Rusanov scheme is used for numerical modeling of the dynamic propagation of elastic disturbances. Special attention is paid to the presence of separate inclusions of pores or fractures, which introduce heterogeneity into the medium and can substantially influence the response of elastic disturbances. The use of the chimera grid method allows for both the position and shape of such inclusions to be described explicitly, taking into account their influence on the propagation of elastic disturbances. As a result of the conducted investigation, a methodology for numerical modeling of the propagation of elastic disturbances in media with porous and fractured inclusions was developed, which can be used to assess the influence of such inclusions on the dynamic response of elastic disturbances. The presented results can be applied in geophysical and seismic research related to modeling the dynamics of various processes in soils and rocks.

A quantum model for the interaction of a collectivized conduction electron with a crystal field in a homogeneous and isotropic deformed polycrystalline sample, taking into account the spin-orbit interaction, is proposed. A dynamic equation of motion of the conduction electron spin in a stress-strained metal is obtained. It is shown that under conditions of inhomogeneous torsion in the stationary case, the average spin of conduction electrons is oriented predominantly along the current density vector. The maximum value of the spin-orbit interaction is observed when the torsion axis is orthogonal to the current density vector.

A dynamic 3D thermoelectric model has been developed to calculate the temperature field and emitter current density in the comb structure of a heterojunction bipolar transistor (HBT) with the length of the emitter metallization paths comparable to the size of the crystal, taking into account the inhomogeneous distribution of current density under the emitter paths caused by a voltage drop on the resistance of the current-carrying metallization. The model is based on an iterative solution in the COMSOL Multiphysics software environment of a non-stationary heat equation together with a system of equations for the distribution of electric potential along the emitter path and the current density under the path. It is shown that during the action of the heating power pulse in the HBT, the distribution of temperature and current density along the emitter tracks change character, respectively, from homogeneous and monotonically decreasing to non-monotonically changing. At the same time, the maximum temperature and current density reach stationary values with a rate significantly exceeding the rate of overheating increase with homogeneous heating of the structure, and the maxima of temperature and current density in the process of self-heating shift from the beginning to the center of the tracks. The proposed model can be used to evaluate the thermomechanical stresses in the structure of the HBT and the limiting electrical parameters in the pulsed modes of operation of the HBT.

The application of a grid-characteristic method is proposed for numerical simulation of the movement of rolling stock along a railway track laid on an earth and a bridge. In the study, the railway track is presented using a dynamic system of equations of the theory of elasticity of hyperbolic type. The grid-characteristic method relies on the characteristic properties of the system under consideration and uses finite-difference schemes of high order of accuracy to obtain a space-time solution. The features of railway structures are considered by changing the boundary conditions and conditions at the contact borders. To simulate the areas of contact of wheel pairs of rolling stock with the rail – the "wheel-rail" system – a previously developed pressure boundary condition is applied, modified so as to consider multi-element rolling stock. As a result of computer simulation of the movement of rolling stock along the railway track of various types, full-wave stress distribution in the track structure is obtained, which makes it possible to predict dangerous sections of rolling stock movement.

The methods for the artificial hydraulic structures condition monitoring using trace microwave radiometers are considered, in order to timely detect places of underground leaks to ensure trouble-free operation. Several practical examples of the use of microwave radiometers on various ground-based mobile carriers are described. The characteristics of microwave radiometers used in practice for hydrological monitoring of earthen dams are given. The possibility of detecting potentially dangerous sections of dams, places of erosion of the dam cover, possible places of underground leaks is shown. The possibility of combining microwave radiometers with other means of remote sensing, such as optical video cameras, thermal infrared cameras and georadars, is being considered. The advantages of multisensory sensing to increase the reliability of detecting places of underground leaks are substantiated.

The dependence of the XML markup of a digital document in the ODT format on the tool that was used to create it is considered. Not only specialized tools are used in comparison, but also those that do not directly work with the ODT format to identify the most vulnerable spots. The features of extracting data from the structural elements of the document, such as tables, lists and images, are also described. The implementation of an algorithm for obtaining style attributes used to create a system for automated normative control of digital documents is proposed and described. It is revealed that the non-strict standard of the ODT format led to the dependence of XML markup on the text editor that was used to create the document. And, as a result, to a limited number of tags that can be relied upon when developing document parsing algorithms. However, the task is feasible, as demonstrated in the article. Likewise, the default values, the description of the algorithm for bypassing the document in blocks and structural elements form the basis for preparing data for the subsequent creation of a classifier and automation of the process of normative control. Thus, the algorithm proposed in the article and the analysis of XML markup performed are effective tools for solving the problem of creating an automated document standard control system, and the algorithm has the potential for further improvement.

Today the apparatus for modelling non-stationary time series is most in demand in various areas of human activity: meteorology, sociology, medicine, financial market research, and a number of others. The general scientific problem of modelling such series is associated with solving the problem of identification, namely, obtaining such model parameters that would provide a high degree of accuracy and adequacy of the model. However, the problem of bias of least square method (LSM) estimates arises when solving the problem of parametric identification of distributed dynamic processes. There are various possible solutions to this problem. If the time series is trend-stationary, then these may be "ostationation" methods, which are generally difficult to apply. It is possible to use dimensionality reduction methods, but in this case we will still get biased estimates. In our previous works, it was shown that the problem of biased estimates can be solved using the conservativeness condition. The aim of this work was to investigate the possibility of using the conservativeness condition to improve the quality of estimates of the parametric identification problem, as well as to compare these results with the solution of the problem, in the case of applying a filter to it, as well as ridge regression.

The article is devoted to the construction of a mathematical model for delaying claims in a queue in the form of a queuing system (QS) described by right-shifted hyper-Erlang and second-order Erlang distributions. This article is a logical continuation of the previous works of the author. In the article, the Erlang distribution is considered as a special case of the more general Gamma distribution law, in contrast to the normalized Erlang distribution. These two forms of the Erlang distribution differ in numerical characteristics, except for the coefficient of variation. To solve the problem, we used the method of spectral solution of the Lindley integral equation.
