In the context of rapid urbanization of society, modeling the processes of sustainable urban development has attracted considerable attention from scientists. This paper presents a study of fuzzy cognitive maps (FCMs) as an interdisciplinary model for simulating urban development processes. This highlights the versatility of FCM in integrating expertise and quantifying the impact of indicators that shape urban space, from infrastructure and housing to environmental sustainability and community well-being. The study uses a synthesis of an extensive literature review and expert opinions to create and refine a cognitive map tailored for municipal development. The methodology outlined formulates a systematic approach to selecting concepts, assigning weights, and validating the model. Through collaboration with cross-disciplinary experts, the study confirms the value of FCM for identifying cascading effects in the decision-making process when shaping urban development strategies. Recognizing the limitations of expert methods and the fuzzy nature of data, the article argues for the effectiveness of FCM in not only identifying but also addressing emerging urbanization problems. Ultimately, this article contributes a nuanced perspective to strategic planning discourse by advocating for the use of NCC as a management decision support tool that can assist policymakers in achieving a sustainable and equitable urban future.

Stepper motors are often used in automated laser cutting systems. The control circuit of a stepper motor requires a special electronic device - a driver, which receives logical signals as input and changes the current in the motor windings to provide motion parameters. This research study evaluated stepper motor drivers to determine the feasibility of their use - PLDS880, OSM-42RA, OSM-88RA. To control the system, software code was written, which was connected to the controller via a link board. With each driver, in different modes, optimal parameters were selected (initial speed, final speed and acceleration), that is, the movement of the carriage without stalling for ten passes with a minimum travel time. The results of the experiments are presented in the form of tables.

In this paper, we reviewed and analyzed various time series forecasting models using data collected from IoT mobile devices. The main attention is paid to models describing the behavior of traffic in telecommunication systems. Forecasting methods such as exponential smoothing, linear regression, autoregressive integrated moving average (ARIMA), and N-BEATS, which uses fully connected neural network layers to forecast univariate time series, are covered. The article briefly describes the features of each model, examines the process of their training, and conducts a comparative analysis of the quality of training. Based on data analysis, it was noted that for the UDP protocol, the ARIMA model has the best learning quality, for the TCP protocol - linear regression, and for the HTTPS protocol - ARIMA.

The possibility of architectural and spatial organization of a series of urban interiors located along the route of communication between buildings and faculties of university complexes of an “integrated” and “distributed” type is being considered. Requirements for such transit spaces are being formed. Options for a scenario for organizing such spaces are proposed, which is an algorithm for the spatial formation of successive functional zones and the student’s consciousness throughout the process of movement and learning. “Architectural-environmental modules” are proposed as a structural unit, including various equipment options and small architectural forms - as a means of organizing spatial scenarios. A typology of similar modules has been developed for various transit zones and types of urban spaces. This approach allows us to form and support the brand of the university as a unified communication space.

Water saturation of soils in the area of foundations is accompanied by a deterioration in their bearing capacity and is often detected only with the appearance of the first signs of deformation. Effective monitoring of soil conditions helps reduce escalating damage. For this purpose, a variant of dynamic penetration was developed and applied, which made it possible to establish a fivefold reduction in the resistance of soils to indenter penetration in the water-saturated zone in comparison with their natural state. The approach provides rapid mapping of the state of the soil mass in areas of expected soaking, for example, in the area of backfilling of foundations. The results are applicable for monitoring soil soaking in technogenic conditions and are of interest to a wide range of specialists in the field of construction.

This work examines the functioning of a team of agents united through a network, and considers the architecture of a distributed data processing system based on an overlay network. The goal of this work is to develop a comprehensive solution that provided signal preprocessing, reliability of data storage and transmission, and high speed of decision making. The distributed key-value storage Etcd has been integrated with the implemented overlay network client by using the tun interface on each agent. The client encapsulates the transmitted IPv4 data packets for further sending through the underlying IPv6 network using a protocol that ensures reliable delivery. The solution considered in the work allows you to autonomously create quickly deployable network exchange mechanisms and guarantee data delivery with an acceptable delay in conditions of interference, jitter, fluctuations in packet delivery delay, and packet non-delivery.

The article is devoted to the problems of managing the implementation of multi-scenario, multi-stage projects under conditions of uncertainty. The proposed approach is based on representing the project model in the form of a scenario network. The developed fuzzy linguistic model of a project stage is a set of linguistic variables corresponding to the stage indicators and external factors influencing the subsequent implementation of the project. The decisive rules for choosing the arc of transition to the next stage are constructed in the form of fuzzy products, the left parts of which are fuzzy statements regarding the preference of possible options. The constructed decision support procedure is based on the use of the Mamdani fuzzy inference algorithm, which has high interpretability. The proposed approach allows for multi-scenario planning and adaptability of management of the implementation of multi-stage projects.

The large-scale development of Russia's lands led to the creation of a railroad network. Along with the laying of the railroad, the entire transportation infrastructure, such as bridges, tunnels and overpasses, was erected. Many structures are already more than 100 years old. The structures are deteriorating and approaching the end of their life cycle. It is therefore necessary to reconstruct or dismantle these structures. Due to the increased freight traffic between China, Russia and Western Europe, it is necessary to reconstruct all tunnels on the BAM. This paper presents one of the tunnel reconstruction options and investigates by mathematical modeling the stress-strain state of the system "array-construction" by which the tunnel can be reconstructed.

Currently, a large amount of research is devoted to the use of polymer composite materials applied for increasing the strength and durability of reinforced concrete elements. In compressed reinforced concrete columns, the bearing capacity depends on the eccentricity of the external force application and the corresponding stress-strain state, as well as on the arrangement and quantity of composite materials bonded to the surface of the structure. The choice of the arrangement scheme of composite materials depending on the stress state of the structure is of current interest for researchers. At the same time, studies conducted on centrally compressed elements often have contradictory effects. The main purpose of this study is to perform numerical experiment of a digital model for the centrally compressed concrete column reinforced with composite materials. The calculation results for 3 short columns with different reinforcement schemes are presented. It is shown that the use of composite materials to reinforce structures increases the bearing capacity up to 10%. Based on the study results, recommendations on the optimal schemes of reinforcement with composite clamps of inflexible columns reinforced in the transverse direction are proposed.
