A reproducible method is presented for the autonomous determination of the coordinates of the base stations of fourth-generation mobile radio networks and the parameters of their sectors, based solely on field observations of the modem without using time delay and methods for estimating the angles of arrival of the signal. The approach combines robust allocation of an informative "core" of measurements, weighted minimization of distances and aggregation at the site level, providing stable estimates in urban environments. Experimental verification in a real scene demonstrates a significant reduction in localization error compared to the basic centroid and median methods, which confirms the practical applicability of the proposed solution.

The article discusses the current threats posed by unmanned aerial vehicles and their impact on the development of the legal and regulatory framework for construction safety in Russia. Based on an analysis of regulatory documents, the article explores the phenomenon of law substitution and the obsolescence of the legal and regulatory framework for construction safety. The author proposes an initial approach to addressing these issues by modernizing the legal framework for building and structure safety. To achieve this, the author has formulated new concepts that are recommended for inclusion in the key law and that lay the foundation for a new institution of unmanned (anti-drone) security in the construction industry.

Electrocardiogram (ECG)-based biometric authentication systems offer intrinsic resistance to spoofing due to their physiological uniqueness. However, their performance in dynamic real-world settings, such as wearable devices or stress-induced conditions, is often compromised by noise, electrode displacement, and intra-subject variability. This study proposes a novel hybrid framework that enhances robustness, ensuring high authentication accuracy and reliability in adverse conditions, through integrated wavelet-based signal processing for noise suppression and a deep-learning classifier for adaptive feature recognition. The system employs preprocessing, QRS complex detection, distance–deviation modeling, a statistical comparison method that quantifies morphological similarity between ECG templates by analyzing amplitude and shape deviations and an averaging-threshold mechanism, combined with a feedforward Multi-Layer Perceptron (MLP) neural network for classification. The MLP is trained on extracted ECG features to capture complex nonlinear relationships between waveform morphology and user identity, ensuring adaptability to variable signal conditions. Experimental validation on the ECG-ID dataset achieved 98.8% accuracy, 95% sensitivity, an Area Under the Curve (AUC) of 0.98, and a low false acceptance rate, outperforming typical wearable ECG authentication systems that report accuracies between 90% and 95%. With an average processing time of 8 seconds, the proposed method supports near real-time biometric verification suitable for healthcare information systems, telehealth platforms, and IoT-based access control. These findings establish a scalable, adaptive, and noise-resilient foundation for next-generation physiological biometric authentication in real-world environments

Experimental studies have been conducted on a method for obtaining a highly dispersed water-air mixture for flotation wastewater treatment using vortex mixing devices. In the course of experimental studies, the patterns of changes in the circumferential (radial) flow velocities of a single-phase liquid (pure water) in the annular space of the barrel of a vortex mixing device at different diameters of the central rod were determined. Experimental studies were carried out at different heights of the H trunk (0.5 m, 1 m, 1.5 m and 2 m) with and without enamel coating of the flow part

The purpose of the article is to study the possibility of the influence of various factors affecting the process of eliminating a water pipeline accident based on its modeling using fuzzy logic methods. The article discusses various options for managing the process of eliminating a water pipeline accident and, during the analysis, determines a set of qualitative parameters that are used in the fuzzy inference model based on the Mamdani method. To build a mathematical model, 37 products were formulated with the help of a group of experts, so that the model can work with selected qualitative variables as with quantitative ones and track the changes that occur in the process. The result of the inference cycle is a clear value of the parameters describing the possible actions necessary to eliminate the accident. The resulting mathematical model allows you to analyze the input parameters at a qualitative level, gives a qualitative representation of the result at the output, which will increase the effectiveness of actions aimed at eliminating a water pipeline accident. The quality of functioning of the described model is verified by a group of experts.

The article is devoted to the problem of verification of distributed algorithms using formal methods. The classical leader selection algorithm in ring topology, the ring algorithm, is chosen as the object of research. For its analysis, the specification language of the Temporal Logic of Actions (TLA+) is used. The paper presents a detailed formal model of the algorithm, describing its states and transitions, taking into account the features of distributed systems, such as the lack of shared memory. The key properties of correctness are formulated and proved: the uniqueness of the leader (the property of security), the finality of elections (the property of liveliness) and consent. The correctness of the specification was confirmed using the model model verifier of the language of temporal logic of actions, which exhaustively checked all achievable states for the model with three processes. The results demonstrate the effectiveness of the Time Logic Specification language (TLA+) for providing a high degree of confidence in the reliability of distributed systems.

The principles for constructing a spatial feature map are described, incorporating geometric characteristics such as the terrain roughness index and a fuzzy traversability index. A modular structure of the following blocks is proposed: data preprocessing, geometric property computation, segmentation, and decision-making. Test results demonstrate the advantage of combining kinematic and sensor-based models for autonomous navigation in complex environments.
