  • Modeling and experimental study of influence of pressure in the gas supply system of plasma installation on the flow velocity

    The article is devoted to the study of the flow rate depending on the pressure in the gas supply system of the plasma head. The problem was solved by conducting a computer experiment with subsequent verification of the results by a full-scale experiment. The laboratory plasma installation MAK-10 assembled on the basis of the IMET UB RAS, used in the processes of coating, powder production and surface modification of parts, was simulated. The computer experiment was carried out using the SolidWorks Flow Simulation software package. As a result of the work performed, the distribution of the flow rate along its axis was demonstrated during the operation of the plasma installation with a pressure in the gas supply system of 0.1; 0.2 and 0.3 MPa. Recommendations for conducting coating, powder production and surface modification processes have been developed, which have practical benefits for consumers of process equipment.

    Keywords: mathematical model, flow, velocity, pressure, plasma method, powder production, coating, surface modification

  • Development of a system for detecting areas with defects in the development of corn crops based on photos from UAVs

    In this work, the developed system for detecting areas with defects in the development of corn crops was investigated from a photograph taken by an unmanned aerial vehicle (UAV) using computer vision. To solve the problem of detecting such sites, the structures of the YOLOv5 and YOLOv8 neural networks were considered. The use of the developed software will reduce labor and time costs for image analysis, which in turn will reduce the response time when problem areas are detected in agricultural fields to achieve higher yields.

  • Organizational and methodological aspects of the survey of enclosing structures of buildings

    The article discusses the organizational aspects of the inspection of building envelopes and structures within the framework of construction and technical expertise using an instrumental measuring method. The implementation of a comprehensive field survey in identifying certain structural defects is necessary, however, the methods used by experts have significant differences in the accuracy of the results provided and the simplicity and ease of implementation, which affects the progress of the work.

  • Experience with the YOLOv5 neural network for sunflower plant detection

    This article describes the results of research on the possibility of detecting sunflower plants from photographs taken by a UAV. The solution to this problem will allow automated control of an important agricultural parameter - seedling density. The problem is complicated by the limited amount of training sample and "disturbances" associated with field weeding. As the result we obtain that the YOLOv5m neural network is capable on a sample of 122 pictures to qualitatively detect plants with an error of 0.077% of training. Artificially increasing the sample to 363 pictures reduces the learning error to 0.063%. Disturbances reduce the detection efficiency of sunflower plants in the test images. It is possible to increase the detection efficiency either by adding original images to the training sample or by artificially enlarging the sample.

  • Problems of construction and technical expertise in determining the volume and cost of actually qualitatively performed works

    The construction industry at all times was one of the most popular, as it is closely connected with the life of people. The stronger the population of our planet grows, the more it becomes necessary to erect an ever larger number of be it industrial or residential buildings and structures. This article discusses the problems of technical expertise in determining the volume and cost of actually high-quality work performed. The main problem is that most of the works carried out during construction (repair) are hidden and it is not possible to verify them, therefore, the expert in this examination is forced to be guided by the acts of examination of hidden works and the journal of the work. One of the main causes of disputes between the customer and the contractor is the overestimated volume of work performed, as well as poorly executed work.

  • Features of technical operation of cultural heritage objects

    This article discusses the features of technical operation of cultural heritage objects. The relevance of the topic is that cultural heritage objects, like any real estate objects, need constant measures to maintain the working condition, as well as to preserve consumer properties, and this action requires special attention and rational approaches. Guided by the guidelines for the operation of cultural heritage objects of the peoples of the Russian Federation, the owner or other legal owner of the cultural object must comply with the requirements of regulatory documents for the preservation of the object in order to increase its service life. Thanks to a comprehensive approach to improving the method of restoration of objects of historical and architectural significance, it is possible to increase the interest of tourists to cultural objects and ensure their safety.
