The purpose of this work is to study the thermal stress of the furnace of a fire-tube boiler and its effect on the design of the boiler. To study the effect of thermal stress and furnace proportions on the ratio of heating surface areas, the calculated resistance was tested. Calculations of heat-tube boilers of sectional hot-water boilers with different proportions of the furnace at different thermal loads of the same furnace volume are performed. The calculation of each heating surface is carried out by the method of successive approximations, based in this case on the chord method. In the calculation process, the flue gas temperature at the outlet of the heating surface was first set, and then refined by successive approximations. To reduce the overall balance of the boiler, another global approximation is made when the temperature determined at the outlet of the last heating surface is set at the beginning of the calculation – in the heat balance, where it affects the loss with outgoing gases and the efficiency of the boiler. It is determined that the optimal.

The paper considers the choice of the optimal technology for the construction of tongue-and-groove fencing based on the hierarchy analysis method. Decision-making in construction practice requires consideration of many factors, including internal (cost, reliability, speed of work) and external local conditions (risk of interruptions in the supply of materials, the influence of weather conditions, work in cramped conditions). The hierarchy analysis method makes it possible to formalize the decision-making process by structuring the task in the form of a hierarchy and comparing alternatives in pairs. In the course of the study, a comparative analysis of the technologies of hammering, vibration immersion and static indentation of sheet piles was carried out. Priority vectors for each criterion were calculated, and the consistency of the matrices was checked. The final choice of technology is justified based on the integration of internal and external factors. The results obtained allow us to recommend the optimal technology that takes into account the technical and organizational features of the construction process.

The increase in the length of asphalt concrete roads increases the importance of efficient asphalt concrete plants in road construction. Modern environmental requirements and rising fuel prices determine a decrease in the temperatures of cooking and laying ABS. In foreign and domestic practice of road construction, warm asphalt concrete mixtures are increasingly used, including with the use of zeolite. The prerequisites for the study of warm asphalt concrete using zeolite in the Republic of Tatarstan is the presence of one of the largest deposits of zeolite-containing rocks of the Russian Federation - Tatarsko-Shatrashansky. Pilot production implementation of the research results was carried out during the construction of an experimental section on the highway – the entrance to the locality of Klyuchishchi in the Verkhneuslonsky district of the Republic of Tatarstan with an upper layer of warm asphalt concrete coating using zeolite. The results of the material indicators that meet the regulatory requirements have been obtained.

Image super-resolution is a popular task that aims to translate images from low resolution to high resolution. For this task, convolutional networks are often used. Convolutional neural networks, have a great advantage in image processing. But despite this, often information can be lost during processing and increasing the depth and width of the network can make further work difficult. To solve this problem, data transformation into frequency domain is used. In this paper, the image is divided into high frequency and low frequency regions, where higher priority is given to the former. Then with the help of quality check, and visual evaluation, the method is analyzed and the conclusion regarding the performance of the algorithm is drawn.trial enterprise.

This article identifies the main advantages and disadvantages of using VR simulators to improve the professionalism of employees when performing work at an enterprise (organization). An analysis of existing projects used in various industries was carried out. A description of the developed first aid project is presented. The developed simulator allows you to practice skills in eliminating bleeding in different parts of the body: arm, leg, neck. While working on the project, the main factors influencing the quality of the developed VR simulator were identified. Thus, it was found that VR simulators are not capable of fully simulating fine motor skills of the hands. In addition, the simulator has restrictions on the position of the body in space. Despite the identified shortcomings, the use of the simulator allows you to practice key skills in providing first aid.

This article is dedicated to developing a method for diagnosing depression using the analysis of user behavior in a video game on the Unity platform. The method involves employing machine learning to train classification models based on data from gaming sessions of users with confirmed diagnoses of depression. As part of the research, users are engaged in playing a video game, during which their in-game behavior is analyzed using specific depression criteria taken from the DSM-5 diagnostic guidelines. Subsequently, this data is used to train and evaluate machine learning models capable of classifying users based on their in-game behavior. Gaming session data is serialized and stored in the Firebase Realtime Database in text format for further use by the classification model. Classification methods such as decision trees, k-nearest neighbors, support vector machines, and random forest methods have been applied. The diagnostic method in the virtual space demonstrates prospects for remote depression diagnosis using video games. Machine learning models trained based on gaming session data show the ability to effectively distinguish users with and without depression, confirming the potential of this approach for early identification of depressive states. Using video games as a diagnostic tool enables a more accessible and engaging approach to detecting mental disorders, which can increase awareness and aid in combating depression in society.
