Authors: Конкин Н.А. 
Published: February 2025

КВ-связь получает современное развитие благодаря расширенному внедрению IT-технологий и методов активной сенсорной диагностики радиоканалов. Рассмотрена задача применения алгоритма машинного обучения XGBoost для анализа изменчивости верхней границы полосы прозрачности линии связи. Анализируются вопросы длительности периодов прогнозирования максимально применимой частоты для заданных ошибок в случае применения настройки гиперпараметров и без неё. Для реализации алгоритма и его расширенного применения создан класс программ на языке Python. Верификация разработки выполнена на основе экспериментальных данных, полученных в Поволжском государственном технологическом университете на среднеширотной радиолинии протяжённостью 2 600 км. Установлена возможность существенного (7 раз) увеличения периода прогноза.
HF radio communication is further developed due to the use of IT technologies in terms of machine learning and neural networks, as well as the development of sensor diagnostics of radio channels. The paper investigates the application of the XGBoost machine learning algorithm to analyze the variability of the upper limit of the transparency band of a HF communication line (MUF). The goalis to develop an algorithm for determining the optimal periods of MUF prediction in the case of hyperparameter tuning and without it. Based on the prepared MUF time series, the optimal (minimum and maximum possible) periods of MUF forecasting were determined based on training samples compiled from experimental data of radio sounding of short-wave communication channels obtained using equipment on a mid-latitude radio link with a length of 2600 km. A database of machine learning models for the XGBoost algorithm has been formed, which will avoid the procedure for pre-tuning the prediction algorithm. To assess the accuracy of forecasting, the metrics of the mean absolute error (MAE) and the coefficient of determination were used. It has been established that hyperparameter-tuned models for the range from 1 to 7 days give the best result in terms of the mean absolute error metric by 25% (average MAE was 1.43 MHz), in terms of determination coefficient by 8% (average value was 0.94). It was experimentally determined that the minimum forecast period is the range of one day, while the value of the average absolute error was 0.78 MHz (at the peak up to 0.84 MHz), and the coefficient of determination was 0.97 (97% convergence of the forecast model and the practical time course of the MUF). At the same time, the maximum forecast period is 7 days and for it the average MAE value is 0.99 MHz, and the coefficient of determination is 0.95. For the practical implementation of the developed algorithm, a class of programs was created in the Python programming language, which assumes their extended use for frequency support of HF communication systems.

В основу положено измерение комплексных значений напряжённости электрического поля в ряде точек, расположенных в зоне ближнего излучённого поля с последующей реконструкцией пространственного распределения источников излучения. Оценки, полученные в результате проведённого моделирования, показывают возможность надёжного обнаружения и локализации мест «утечки». Проведён анализ возможностей и путей практической реализации измерительной аппаратуры.
Introduction. The operation of industrial installations utilizing microwave technologies inevitably results in the unintentional emission of electromagnetic energy beyond the confines of these installations or even the industrial premises. Often, the design of microwave and high frequency (HF) equipment for industrial applications falls short in providing adequate shielding against electromagnetic field leakage. The existing equipment employed by regulators is primarily designed for measuring overall levels of electromagnetic fields and doesn’t fit for localizing the specific areas where electromagnetic energy 'leakage' occurs. Utilizing the technical equipment used by radio monitoring services for these purposes is impractical due to its high cost, rendering it inaccessible for widespread use in addressing electromagnetic environmental concerns. Consequently, the development of affordable and straightforward methods and tools for identifying and monitoring sources of electromagnetic pollution represents an urgent challenge. The aim of this research is to establish principles and methods for creating equipment capable of detecting and localizing inadvertent microwave radiation emissions originating from industrial and agricultural technological installations. The paper introduces a novel approach for designing equipment aimed at environmental electromagnetic monitoring. This approach revolves around measuring the complex values of electric field strength at multiple points within the vicinity of the radiated field. Subsequently, it involves reconstructing the spatial distribution of radiation sources. Findings. We've developed a novel control methodology that serves as the basis for creating equipment capable of detecting 'leakage' of electromagnetic energy from industrial microwave installations and then pinpointing their source through an innovative process of reconstructing radiation source distribution. Computational modeling has confirmed that the necessary hardware for implementing this measurement system can be developed using readily available components.

Introduction. The reasoning for integrating vulnerability scanners with systems for monitoring information security risks arises from the limitation of using each product independently, as it hinders the establishment of comprehensive protection for critical resources. This outcome is supported by a thorough examination of the currently employed scanners and monitoring systems. This study aims at enhancing the efficiency of data collection from network infrastructure, reduce processing time, and elevate the quality of information security threat management. Research Methodology. To accurately compute output probabilities, the adoption of intelligent analysis methods is proposed. These methods are capable of swiftly processing vast datasets and eliminate the potential influence of human error. Findings. The algorithm presented here holds the potential to enhance the efficiency of information security threat management. This conclusion is supported by the algorithm's capability to establish connections between vulnerabilities and information security threats, thus recognizing them as interdependent entities. Furthermore, the algorithm's design, based on the proposed integration approach, distinguishes between vital and less critical data, streamlining the analysis process. The incorporation of intelligent methods additionally expedites data processing and decision-making. However, even without considering these methods, the proposed algorithm is already effective in substantially reducing the most critical parameters, including time, error probability, and data processing volume. Conclusion.Consequently, integration paves the way for fully automating the information security process.

Introduction. Definition of germinating capacity and viability of seeds is of significant importance for introduction. There are no references to American larch (Larix laricina L.) in the standards for definition the sowing qualities of seeds and for determination the degree of quality for the seeds of coniferous species (12 kinds of larches are included). The goal of the research is to study the variability of morphological characters of cones, needles and seeds of American larch (Larix laricina L.) as well as to carry out the analysis for sowing qualities of seeds of American larch, growing under the conditions of introduction. Objects and methods of research. American larch was introduced in the Main Botanical Garden (Moscow) in 1956. Fifty nine trees were grown from the seeds brought from the USA and Canada. Germinating capacity, viability, and degree of quality of seeds were determined in accordance with the international standards. The samples of cones and needles for the research purposes were collected in the sunny side of the bottom of tree crowns. Results. There is a substantial similarity between American and European larches on the dynamics of seed germination. This makes it possible to use the recommendations of the standards for European larch to define the germinating capacity of the seeds of American larch. Germinative energy and germinating capacity of the seeds of American larch were 8 and 15,8 % accordingly. Using the requirements of the standards for determination the degree of quality of seeds of European larch, the seeds of American larch may be designated as the seeds of 2 degree of quality. The share of viable and germless seeds of American larch under the conditions of introduction is very close to the figures for European larch. To estimate the seed qualities of American larch, it is possible to use the parameters recommended GOST 14161-86 (Government Standard) for the seeds of European larch. Conclusion. Under the conditions of introduction, low germinating capacity of seeds is determined. It is explained with the particularity, typical for Larix Mill at large and Americal larch in particular. It is recommended to use GOSTs (Government Standards) elaborated for European larch.

Цель исследований заключалась в изучении влияния технологических факторов при получении растительного пластика на основе шелухи проса (Panicum miliaceum) и оценки его физико-механических свойств. Установлено, что требуется разработка определённого подхода к получению растительного пластика на основе шелухи проса (использование других режимов прессования, использование различных модификаторов). Изучена динамика изменения свойств изделий по отношению к активному грунту в течение трёх недель. Дана оценка биостойкости получаемых материалов по отношению к активному грунту. Выявлены низкие прочностные свойства и водостойкость у изделий на основе растительного пластика на основе шелухи проса после испытаний на биостойкость, что косвенно подтверждает возможную эксплуатацию данных материалов в местах, подверженных биологической деградации только после соответствующей антисептической обработки.
Introduction. Nowadays a large amount of secondary wastes of plant origin are generated. One of the ways to treat the wastes is to get the plant-based plastics without any binding material (RP-BS). The main danger for plant-based plastics in the process of storage and operation is the tendency to bio-damage which is caused by different fungi. The purpose of this study was to experimentally evaluate the biodegradation of plant-based plastics without binders on the basis of agrarian wastes in active soil to the change of physical and mechanical properties. Objects and methods of research. Products made of RP-BS and based on pearl millet husks were the object of the research. The objects of comparison were products of RP-BS on the basis of pearl millet husks and products made of wood plastic without binders (RP-BS) based on wood sawdust. Active soil (a mixture of sand, horse manure and garden soil (equal quantity)) was used to assess the biodegradation. The studied samples of RP-BS and DP-BS were placed in a container with active soil. The duration of exposure of samples in active soil at room temperature was 14 days. Before and after testing for biodegradation in active soil, the initial physical and mechanical properties of RP-BS and DP-BS samples were determined. Research results. The dynamics of changes in the properties of products in relation to the active soil within 3 weeks was studied. Bio-resistance of the obtained materials in relation to the active soil was assessed. For RP-BS on the average (for all batches) the hardness reduction was 70 %, the number of elasticity – 47 %, compressive modulus of elasticity – 80 %, breaking stress – 68 %, yield strength – 68 %. Conclusion. Low strength properties and water resistance of the products based on plant plastics on the basis of pearl millet husks after bio-resistance tests were revealed. It indirectly confirms the possible operation of these materials in places subject to biological degradation only after the appropriate antiseptic treatment.

Background Cryotherapy, long used for its pain-relieving and anti-inflammatory effects, is widely applied in sports medicine, physiotherapy, and postoperative care. Advances in cryotherapy methods, including the use of topical vapocoolant sprays, offer enhanced pain management and support recovery from musculoskeletal injuries by alleviating pain and reducing swelling in a targeted manner. Hypothesis/Purpose The primary aim was to assess both immediate and sustained pain relief in subjects with mild to moderate musculoskeletal complaints. Study Design Observational cohort study. Methods Fifty-nine participants with mild to moderate musculoskeletal pain participated in a three-week observational study evaluating a cryotherapy spray. Pain and range of motion (ROM) were assessed using the Visual Analogue Scale (VAS) and goniometer measurements at multiple time points, including T-1 (before treatment), T0 (beginning of treatment), T2-min, T5-min, T10-min, T15-min, T30-min, T60-min, T7-days, T14-days, while participants were actively receiving treatment exclusively with the cryotherapy spray, and T21-days (1 week after treatment cessation). Acceptability Test and additional subjective questionnaires evaluated participants analysis of cooling sensation and product tolerance. Data were analyzed using Cumulative Logit Mixed Models (CLMM) and the non-parametric Friedman test for repeated measures. Results The cryotherapy spray significantly reduced pain (VAS) from baseline (p < 0.001, Hedges’ g = -1.90) and improved joint mobility (ROM) with derived scores increasing from 3 (3–4) to 4 (4–4) by Day 21 (p < 0.001). Rapid pain relief was reported by 35% of participants within 10 seconds, with 80% experiencing relief within three minutes. Comfort ratings were consistently high, with 95% of participants expressing satisfaction at Day 0, rising to 99% by Day 14. Global efficacy satisfaction measured by a subjective Likert scale also increased from 75% at baseline to 95% by Day 14. No adverse events were reported. Conclusion This study supports the effectiveness of the cryotherapy spray in reducing pain and improving joint mobility, with both immediate and sustained benefits. High patient satisfaction and a favorable safety profile suggest its potential for clinical use. Further controlled studies could confirm its efficacy in broader populations. Level of Evidence Level 3
