    Mathematical modeling, numerical methods and program complexes (technical sciences). Geopolitical situation analysis of a number of episodes of the American Revolution in the context of applying structural balance and mathematical modeling methods. Structural balance management can help to find the most optimal strategies for interacting parties. This approach is used in a set of disciplines.

  • Simulation of the design activity diversification of innovative enterprise

    The article discusses options for solving the problem of slowing down the operating cycle of programmable logic controllers that occurs when implementing complex algorithms. For most modern programmable logic controllers, the operating cycle directly depends on the volume of the user program. The program is executed pseudo-parallel, so the complexity of the algorithm affects the slowdown of the cycle indirectly, through an increase in the code volume. The growth of the program leads to a slowdown in the controller's response to changes in the state of the inputs. In some cases, controller developers provide programmers with options that allow them to disrupt the natural order of the operating cycle, thereby reducing the response time. The advantages and disadvantages of such methods are discussed in detail in this article. As an alternative way to reduce the controller's response time, the possibility of transferring the execution of a part of the algorithm to the operator's touch panel is considered. Modern touch panels, in addition to their main task - implementing the human-machine interface, have many additional functions, including the ability to use macros. The main functionality of macros is given and the possibility of exchanging data between the controller and the panel is demonstrated. This feature is a prerequisite for delegating some of the functions of the panel controller. The limitations and risks that arise when using this approach are discussed in detail, and situations in which it is preferable to use this method are identified.

  • Evaluation of the effectiveness of a data set expansion method based on deep reinforcement learning

    The article presents the results of a numerical experiment comparing the accuracy of neural network recognition of objects in images using various types of data set extensions. It describes the need to expand data sets using adaptive approaches in order to minimize the use of image transformations that may reduce the accuracy of object recognition. The author considers such approaches to data set expansion as random and automatic augmentation, as they are common, as well as the developed method of adaptive data set expansion using a reinforcement learning algorithm. The algorithms of operation of each of the approaches, their advantages and disadvantages of the methods are given. The work and main parameters of the developed method of expanding the dataset using the Deep-Q-Network algorithm are described from the point of view of the algorithm and the main module of the software package. Attention is being paid to one of the machine learning approaches, namely reinforcement learning. The application of a neural network for approximating the Q-function and updating it in the learning process, which is based on the developed method, is described. The experimental results show the advantage of using data set expansion using a reinforcement learning algorithm using the example of the Squeezenet v1.1 classification model. The comparison of recognition accuracy using data set expansion methods was carried out using the same parameters of a neural network classifier with and without the use of pre-trained weights. Thus, the increase in accuracy in comparison with other methods varies from 2.91% to 6.635%.

  • Concepts of «symbiosis» of architecture, design objects and monumental and decorative art in the interiors of public buildings in the context of renovation of industrial buildings

    The concept of symbiosis of architecture, design objects and monumental and decorative art in the interiors of public buildings in the context of renovation of industrial facilities is aimed at preserving the historical identity of buildings, adapting them to modern functions and creating a unique aesthetic where architectural forms, design solutions and artistic elements form a single whole. Renovation of industrial facilities involves a number of challenges: the need to maintain a balance between history and innovation, the integration of artistic and functional aspects, as well as compliance with environmental standards. The use of recycled materials, hybrid technologies and "smart" interiors makes it possible to cope with these tasks. The concept of three components contributes to the creation of spaces that become cultural and social centers. Such projects inspire, emphasize the value of architectural heritage and open up new perspectives for the sustainable development of the urban environment, contributing to the formation of emotionally rich and functionally significant interiors that reflect the spirit of the times and preserve the connection with the past.

  • Determination of urban planning factors influencing the efficiency of water use

    The emergence of the city was associated with the need to organize water use, organize irrigation works, create its facilities, which in turn required the management of the organization of these works and the creation of facilities for the exploitation of water in agriculture. Finding an average balance between demand and availability of resources was a priority, especially for areas experiencing water shortages. Then, the reliability of available resources in conditions of drought or shortage became a key issue in order to cope with climate variability. In parallel, climate change will affect the spatial distribution and timing of water availability. As a result, in the future, water shortage in cities may become a much more serious problem, which may jeopardize the achievement of the UN Sustainable Development Goals (SDGs), especially "Sustainable Cities and Communities". Historically, since settlements were located some distance from water sources, a variety of sources and technologies for collection, transportation, treatment and waste collection emerged. Population growth and technological developments have led to the emergence of new forms of alternative resources capable of meeting the needs and specific requirements of water-related activities.

  • Computational study of the deformability parameters of truss structures using wood

    Determining the deformability of the bearing structures of the coating, as an indicator of the use of the stiffness of the cross-section of the elements, is an urgent task, which is aimed at solving the current work. The purpose of the article is a comparative calculation of frame structures under the assumption of a different coating truss solution. The following types of load-bearing roof trusses should be considered: segment truss, trapezoidal truss, triangular truss. The calculation of frames using wood as load-bearing structures for the total effect of permanent and short-term loads causing maximum vertical deformations is given. In this paper, the coefficients of using the rigidity of truss structures using wood are determined and the dependence of the stiffness value on the type of outline of the coating truss is established. A comparison of the calculation results with the normative maximum permissible values allowed us to establish the most effective type of outline of the wooden roof truss.

  • Dependence of the tourist flow on the area of specially protected natural territories of the islands

    Based on statistical data, the article presents a solution to the problem of finding an empirical function that establishes a link between the tourist flow and the proportion of the area of specially protected areas from the total territory of the island. For the analysis, data was collected on 14 islands with a developed tourism industry. Power functions are obtained for two groups of islands with different areas. The obtained dependencies make it possible, at the stage of urban planning analysis of the territory, to determine the permissible value of the tourist flow, which ensures tourist activity based on the principles of sustainable tourism. Using this function, the maximum value of the allowable tourist flow for the island of Socotra has been set, the development of which is focused on the tourism industry.
