Mathematical Models of Socio-Economic Processes
Valuation of machines with a randomly decreasing service life
Resumo
We consider machines that are subject to a Poisson failure stream and whose operational characteristics deteriorate during operation. The market value of the new machine and its assigned service life are known. In case of machine failure, its remaining service life is abruptly shortened by a random value distributed according to a power law. A new model has been built that links the dynamics of the market value of the machine with its remaining service life. This is not enough for a practical valuation, since appraisers often only know their age about cars. However, the machines of the same age may be in different condition, and here appraisers have to rely on the dependence of the average cost of machines on age. We have obtained formulas for constructing similar dependencies, according to which experimental calculations have been carried out. It is shown that such dependencies change little when the discount rate and the assigned service life change, although they differ with different coefficients of service life variation.

Digital transformation of the healthcare system
Resumo
The article provides a brief analysis of the directions of development of the digital economy in the country as a whole, and in the field of health care, in particular, studies theoretical and methodological approaches to the use of information technologies in medicine. It is shown that at first, digital transformation in healthcare was mainly associated with the automation of routine processes. Along with automation, digitalization is now in full swing, aimed at creating intelligent production systems that can adapt to changes in real time. But it should be emphasized that digital technologies are primarily designed to improve the healthcare system, improve quality and effectiveness of medical care. The introduction of digital technologies in medicine does not mean that they will completely replace the doctor.

On interrelation of organizational approaches to strategic analysis in the context of natural monopoly issues
Resumo
The issues of organizational approaches interrelation developed within the framework of general organizational science/ tektology (organizational dialectics as its key component), and in the theory of natural monopoly are considered, with the expansion of the analytical possibilities for application. The methodological provisions of the strategic analysis of organizational transformations, based on organizational dialectics, are presented. The directions for the synthesis of organizational approaches are shown in terms of introducing into strategic analysis the elements of accumulated organizational experience regarding structural changes of railway transport in natural monopoly spheres, clarification the procedures for selecting activities in conjunction with procedures for natural monopoly identification, and expanded opportunities for interpreting identification results based on the ideas of organizational dialectics. The possibilities of involving in the analysis of organizational dynamics a combination of analytical mechanisms of tektology, and the elements of methodological potential of natural monopoly theory, which focused on diagnostics of organizational transformations, are determined.

Classification of a scanned document type using the dynamic time warping method
Resumo
The work addresses an important problem in the field of automatic document image recognition: determining the type of a scanned document from a predefined set of possible types. The proposed document classification method compares parallel projections of the input image with reference projections of templates from the target set, which can be generated using just a few document image samples. The matching is performed using a dynamic time warping algorithm. The classification method requires neither prior binarization of the sample, nor keyword extraction or recognition, nor detection of geometric primitives. However, it does require preliminary image deskewing. Experiments were conducted on a manually normalized dataset of business documents comprising eight distinct types, achieving a classification accuracy of 99.79%. For the same images normalized automatically, the accuracy reached 99.76%. For the document type with the largest average image size (2479х3589 pxs), the average processing time is 12.31±1.53 ms on a PC with an AMD Ryzen 5 5600X CPU, 64GB RAM.

The use of correlation adaptometry techniques to evaluate the effectiveness of the treatment
Resumo
The method of correlation adaptometry was used to process physiological and biochemical data in patients with varying degrees of obesity during diet therapy, as well as in patients with various types of heart surgery. The effectiveness of diet therapy is shown and the effectiveness of the performed operations is evaluated using the technique of correlation adaptometry.

A systems analysis of the significance of factors influencing the epidemiological situation of tuberculosis in Russia
Resumo
A systematic analysis of the interrelationships between the indicators of the epidemic situation of tuberculosis (EST) and economic, demographic and climatic factors has shown that the effectiveness of managing this situation depends on the totality of factors that must be taken into account when developing optimal management strategies both in the Russian Federation and in other countries characterized by significant heterogeneity of regional characteristics. With significant differences between regions, management strategies should be based primarily on specific values of the dynamics of the studied factors within each region, rather than on generalized indicators of the country as a whole. Along with economic indicators, important determinants of EST in the subjects of the Russian Federation are the temperature regime and population density. The general economic level, which determines the quality of life in the constituent entities of the Russian Federation, has a stronger impact on EST than targeted financing of anti-tuberculosis measures.

Information Technologies
Increasing the speed of DBMS operations using hardware FPGA accelerators
Resumo
The article provides an overview of a way to speed up data processing operations in a DBMS using an FPGA. An overview of FPGA capabilities, FPGA usage architectures is performed, and practical examples of FPGA usage are considered. The advantages and disadvantages of using FPGA are determined. A number of problems and alternative technologies were noted, which significantly slowed down the use of FPGAs in industrial DBMS and data storage systems. Using FPGA to speed up data processing in a DBMS, it can be argued that the approach allows you to speed up database operations related to query processing, data compression and encryption, and parallel data processing. However, the use of FPGAs also complicates the system as a whole, does not allow for flexible and quick reconfiguration of the system's functionality, and increases the total cost of ownership. In further research, it is planned to consider alternative technologies for accelerating data processing operations.

Development of an SVM model for predictive maintenance of metal-cutting equipment
Resumo
This article is devoted to the development of a machine learning model for optimizing cutting tool maintenance using the support vector machines (SVM). The paper considers the main stages of creating a multiclass classification model from pre-processing of raw signals to selection of hyperparameters. The choice of the algorithm is determined by computational efficiency, as well as the possibility of working with data with nonlinear structure. As a result of testing the model, the average accuracy reached 81%. The obtained results demonstrate that the algorithm based on the method of support vectors can handle the task in conditions of limited computational power.
