  • Programming the robot controller to implement the technological process of laser cutting

    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.

  • Overview of modern technologies for recycling construction waste

    The article analyzes modern approaches and technologies for recycling and recycling of building materials. Such types of waste as reinforced concrete, brick, glass, wood, plastic, etc. are considered. Special attention is paid to innovative methods of processing to obtain secondary raw materials (recycling). It is shown that the most promising technologies are the crushing of concrete, brick and reinforced concrete for reuse in construction, the melting of scrap metal, glass and plastic, the processing of wood waste into slabs and fuel. There is an insufficient level of application of innovative solutions in Russia. A set of measures has been proposed to improve the efficiency of construction waste disposal: the introduction of advanced technologies, the construction of waste recycling plants, the adoption of a targeted state program, and the improvement of environmental culture.

  • Optimal cutting of rolled metal in the context of two-dimensional design of bar structures

    Bar structures are widespread in construction due to their economy, freedom of design shapes and sizes. As a result, automation of design and calculation of such structures is an urgent task. As part of the study, the task of developing a software module that generates a map of optimal cutting of rolled metal based on the results of calculations of rod structures has been implemented. The algorithm under consideration takes into account such features of the cutting optimization problem as taking into account the width of the blade, the possibility of using half the size of the rolled product, support for optimization of several sections, and welding of parts in case the length of the workpiece is exceeded. The software module is developed using JavaScript and C# languages. The ability to automatically generate cutting maps based on the results of optimization of rod structures increases the efficiency of designing building structures.

  • Analysis of standard models of titanium oxide-based memristors for use in artificial intelligence systems

    The article discusses standard models of titanium dioxide-based memristors. A memristor is similar to a memory resistor and demonstrates a nonlinear resistance characteristic in which the charge parameter is a state variable. They can be used to create new types of electronic devices with high energy efficiency and performance, as well as to create machines that can learn and adapt to changing environmental conditions and in many practical applications: data storage memory (binary and multilevel), switches in logical electronic circuits, plastic components in neuromorphic artificial systems intelligence based on nanoelectronic components. It has been shown that when voltage is applied to charged ions, they begin to drift, and the boundary between the two regions shifts. When a sinusoidal alternating voltage of a given frequency is applied to the memristor, the shape of the volt-ampere characteristic (VAC) resembles a Lissajous diagram centered at the origin.

  • Using fuzzy cognitive maps to solve the problem of municipal development

    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.

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.

  • Designing mechanisms for network data exchange between intelligent autonomous robots based on distributed key-value storage

    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.

  • Intelligent support for adaptive construction of project trajectory

    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.
