To date, the socio-economic situation in the country creates for the population quite significant obstacles in the implementation of tasks for the purchase of housing and other real estate through mortgage lending. However, when it comes to collecting the amounts owed on the loan, banks are faced with an analysis of the prospects for the sale of mortgaged property, as a result of which, in most cases, come to the conclusion that the original sale price of the mortgaged property with the realities of the market. In the article, the authors consider the judicial practice of determining the initial price of the mortgaged property and analyze the situation in which there is a need for judicial value examination, as well as give the main aspects of the methodology of this type of expertise. The purpose of the article is to form a clear idea of the reader about the process of resolving the dispute arising from the breach of obligations under the loan agreement.

The Minsk Motor Plant D-245 engines are the most widely used in automobiles and tractor manufacturing in Russia and neighboring countries. These engines are installed on cars of the GAZ and MAZ family, PAZ buses, special equipment manufactured by Amkodor, MTZ tractors, etc. A turbocharger is one of the engines units affects power and environmental performance. The presence of a large number of engines under consideration makes it important for repair enterprises to improve the technological process of repairing turbochargers. A large number of technologies for repair rotor shaft of the turbocharger have been developed to date. However, there is no technology to restore the outer surface of the rotor seal sleeve after they touch the hole of the middle housing. The article presents the results of calculating the stress-strain state of the rotor shaft of a turbocharger, taking into account the installation of an additional (repair) part as a turbine seal sleeve. The analysis of the created solid-state model was carried out using of the SolidWorks Simulation system. The calculation was carried out at various shaft diameters for bearings. The study found that the voltage in dangerous sections of the rotor shaft with the installed repair sleeve is higher than without it. However, they are much lower than the permissible torsional stresses. Therefore, the probability of destruction of the rotor shaft during normal operation of the turbocharger, due to the occurrence of a resonance phenomenon, even with the minimum allowable diameter, will be very small. The presented data allow the use of this repair method to restore the operability of the rotor shaft of the TKR-6 turbocharger.

In this work, the author has compiled a list of requirements and corresponding indicators that must be taken into account in the process of creating the university timetable and estimates of the significance of each of these indicators are obtained. The task is to formulate directly the timetable formation procedure on the basis of the list of indicators and assessments of their importance. It is supposed to consider the possibility of solving this problem based on the use of its formalized model. To form a model, it is first necessary to formalize all the requirements from their list. There is considered an example of some of these requirements that briefly describe the procedure for their formalization.

An algorithm for determining the lower confidence limit (NDH) for the minimum value of the hardness of a set of machine parts by calculation is developed. For processing of statistical data of the hardness measurements used a three-parameter Weibull distribution is offered. The transition from sample data to population data is carried out by the graphical method. According to the algorithm, NDH was found for the minimum hardness value with confidence probabilities p=0.9; 0.92;0.93;0.94.

Dosing of various substances and materials are widely used in the chemical, petrochemical, food, medical, pharmaceutical, agro-industrial complex and other branches of science and technology. Research and development of new intellectual property objects, including those aimed at increasing the share of labor automation in this area, are actively conducted in many countries of the world. This determines the need for accelerated development of domestic technologies and equipment competitive in the Russian and foreign markets for automated dosing and packaging of various substances and materials, including liquid, bulk, puree, viscous and others. Based on a systematic patent information search, a systematic analysis of technologies, machines and equipment for dosing in industry, agriculture and the social sphere has been performed. A knowledge base has been compiled and systematized in the field of technologies and equipment for dosing in industry, agriculture and the social sphere. The results can be used to develop new technical solutions for improving equipment and technologies used in various fields of science and technology

The authors propose to consider an interesting solution for finding real estate using GIS - technologies. This method can significantly reduce the time it takes to select a property. This article shows how the data processing capabilities of scientific computing tools for Python and the visualization and analysis capabilities of ArcGIS geospatial data can be used to build a model that generates a short list of houses that meet the needs and desires of potential buyers. And although the choice of a house is purely individual, there are a lot of common factors. Such as the total area, the number of floors and rooms, the presence of a garage and much more. Also, when buying a house, you are looking for proximity to services such as food, pharmacies, emergency rooms, child care facilities, parks, etc. You can use the ArcGIS API geocoding module for Python to search for such objects at a given distance around the house. This method suggests combining all the necessary conditions into one system, which will significantly reduce the list of real estate objects on the market and choose the most optimal options.

The basis of solving the problem of automatic takeoff and landing of helicopters is the problem of orientation of the aircraft relative to the landing site. Existing approaches are based on a combination of satellite positioning technology and sensors. Such solutions have a significant drawback - low positioning accuracy. In this regard, it is necessary to develop new methods that provide low computational complexity and high positioning accuracy relative to the landing site. The article provides an overview of modern solutions in the field of autonomous control of aircraft. The concept of a method for solving the problem of orientation of a helicopter relative to the landing pad is proposed. The approach is based on the use of a camera following the heliport sign. Determining the landing site is based on the theory of fuzzy sets and complex linguistic variables. Complex linguistic variables have three-dimensional membership functions, thus avoiding the problem of uncertainty. Simplification of the computational process is achieved through the use of projections of sections of three-dimensional membership functions.

This article analyzes strategies to overcome the risks of a breakdown in the life of a young family. Based on the results of an empirical study conducted in the Rostov region, the authors of the article identify micro- and macro-strategies for overcoming the risks of destroying the life world of a young family within the framework of cognitive, value, and behavioral levels. The authors conclude that an important role in overcoming cognitive-value risks is given to microsocial strategies, where the family occupies key positions. Macro-social strategies are represented by the work of social institutions such as the state, the media, and education. According to the authors, the symbiosis of the selected strategies is the most effective for reducing the risks of the collapse of the life world of a young family.
