Abstract Currently, in various fields of science and technology, there is a fairly large number of methods for predicting reliability indicators, which differ in the set of tasks to be solved and the features of the mathematical apparatus used. When developing a methodology for calculating the reliability of an electric machine, one of the main stages is the development of a mathematical model, in which it is possible to take into account the factors, the impact of which directly affects the technical condition and the level of operational safety. Taking into account the disturbing influences during the implementation of the technological process is possible provided that the means of automation are used. The performed analysis of statistical data on traction motor failures made it possible to substantiate the advisability of warming up, since a significant number of electrical part failures occur in the autumn - winter - spring periods of time. This feature of the distribution of failures is to a certain extent due to the direct wetting of the insulation and a decrease in its dielectric strength. This process is associated with a sharp drop in external and internal temperatures when placing the locomotive at the depot, which contributes to the appearance of condensate on the insulation, its further destruction. The measure proposed in the article for warming up traction electrical equipment is aimed at an integer reduction in the failures of the electrical part of the electric motors under consideration.

This study examines the impact of public expenditure on economic growth in Russia. Fiscal multipliers for various items of government spending are calculated by means of our macroeconomic model of the Russian economy. Resources for fiscal stimulus and optimization are analyzed. In this study we assess Russia’s fiscal sustainability in conditions of various levels of oil prices. We conclude that fiscal stimulus is ineffective in Russia, while fiscal sustainability in conditions of a sharp drop in oil prices is relatively low.

A number of books on Pakistan's economy have recently been published, but most of them do hot provide the latest statistical data or keep pace with events and development during the 1970's. The book under review, however, has admirably fulfilled the requirements. It covers a vast range of subjects concerning economic development in the country during the recent past The book is divided into nine parts and covers such diverse areas as development, industry, the price situation and the impact of inflation, Pakistan's planning and development effort, trade priorities and balance of payments situation, .taxation* foreign aid, and socio-economic reforms. The analysis is general, broadbased, and historical in perspective and a large amount of data have been put together. To bring out a clearer picture international comparisons are made whereever possible, especially in the last part of the book where the author reiterates on the need for a "New World Economic Order".

The mode of development of the COVID-19 pandemic in Russia and the impact of the epidemic on the areas of scientific research, education and functioning of the fuel and energy complex are discussed. The official statistics revealed evidence both of effectivity of the taken anti-epidemic measures in Moscow and of possible cases of incorrectness of statistical data. The social situation and the mode of development of the epidemic in Moscow and in the regions of Russia are essentially different, that reduces the effectiveness of anti-epidemic measures introduced uniformly throughout the whole country. The conditions of the pandemic and quarantine are difficult for everyone, but organizations and persons with a more modern informational character of production adapt to them more easily. In general, it can be suggested that the epidemic besides the very essential losses gives an important impulse for social-economic and political modernization of the society.

Selection Of

Studying the historical facts of past wars and armed conflicts and natural and man-made emergencies, today in the Republic of Kazakhstan one of the most important security issues is the preparation and organization of the evacuation of the population from possible dangerous zones, taking into account the emergence of new threats to the country’s security. The paper presents an algorithm for constructing universal scales of the distribution function of opportunities by types of support and rebuilding them into subject scales using display functions. The purpose of the paper is to determine the integral indicators characterizing the possibility of accommodation of the evacuated population and the impact on resources during relocation. On the subject scales of cities and districts of the region, indicators of the possibility of relocation of a certain amount of the evacuated population by types of support and indicators characterizing the impact on the district’s resources during resettlement of a certain amount of the evacuated population are determined. It was concluded that the use of integrated indicators allows the selection of areas to accommodate the evacuated population without the use of statistical data, in conditions of incomplete and inaccurate information. The presented method does not replace traditional methods based on classical methods of territory assessment by the level of life sustenance, but also allows their reasonable combination with the experience of specialists in this field, taking into account the incompleteness, uncertainty, and inconsistency of the initial data of the study area, which does not allow the application of existing methods.

The research presented in the article, which includes methods, models, and conclusions, contains synthetic and analytical model solutions concerning the problems of the technical maintenance and wear of residential buildings with a traditional construction. The cause and effect relationships between the occurrence of damage in the elements of tenement houses (treated as proof of their maintenance conditions), and the size of the technical wear of these elements were determined using a representative and purposefully selected sample of 102 residential buildings erected during the second half of the nineteenth and early twentieth centuries in Wroclaw’s “Downtown” district. Quantitative damage analysis, which was carried out using empirical (visual) methods of assessing the technical condition of a building, indicates the type and size of damage to the building’s elements that are characteristic for the relevant maintenance conditions. Research concerning the cause–effect relationships (“damage–technical wear”) in observed states allows for a numerical approach to the impact of building maintenance conditions on the degree of the technical wear of its components. The maintenance and exploitation conditions determine the degree of the technical wear of the elements of an old residential building. The exploitation condition of these buildings is manifested by damage to elements caused by water and moisture penetration, which is especially important for poorly maintained buildings. The article shows that the age of the elements of an old residential building with a traditional construction is of secondary importance in the process of the intensity of losing its serviceability value. It was calculated that no more than 30% of the damage of building components is explained by the passage of time, and it is therefore not age that determines the course of the technical wear of the elements of the analyzed tenement houses.
