Purpose. To develop a simulation model of the motion of a group of objects in three-dimensional space to generate datasets and individual samples for further use in training neural networks and developing a mutual positioning system. Methodology. Analytical review, the automated control theory, imitation modelling. Results. Using Python, a 3D model has been developed. Digital and graphical representations of the linear trajectory of movement for a group of 4 drones based on input data, including coordinates of initial and final points and an error range, have been received. Trajectories with compensated and uncompensated deviations have been compared. Approximation and simplifications have been justified by the goal of enabling the use of the model by those without fundamental knowledge of control theory, system modelling or advanced mathematics. Code testing and benchmarking have also been conducted, proving the financial feasibility of the solution. The model will be used by the authors for further research, including assessing the likelihood of obtaining biassed data from sensors of some drones in a swarm and finding ways to correct it. The source code of the developed model is provided for open access. Scientific novelty. An imitation model of interaction and movement in three-dimensional space for a group of autonomous objects has been proposed. These objects, capable of collective decision-making based on swarm intelligence, aim to compensate for errors or interference. Practical significance. Testing in the AWS cloud environment has demonstrated that even with minimal computational power the proposed imitation model yields adequate results, suitable for neural network training.

Authors:   M.S. Poliakov Institute of Geotechnical Mechanics of the National Academy of Sciences of Ukraine, Vynohradov Yurii
Published: February 2024

Purpose. Improvement of the method of reducing water inflows into mine workings with using com-bined frame-roof bolting to ensure the stability of the mine workings, waterproofing and protection against the collapse of wet contour rocks inside the mine workings. Methods. When solving the problem of water filtration in deformed rock, the method of studying the state of a layered rock massif with a mine working in the presence of water-saturated layers in its vicinity, which was developed by the authors, as well as the finite element method, were used. Research results. As a result of the calculations, the stress values, the zones of inelastic defor-mations, the values of permeability coefficients, water pressure and water inflows have been obtained for the roadways supported with different number of roof bolts. It is shown that the number of roof bolts af-fects all these parameters around the roadway in the rock mass and in the water-saturated seam. If a larg-er number of roof bolts are installed, the processes of crack formation and, accordingly, rock fracturing are slower. After mining, if 3 or more roof bolts installed, intensity of water filtration process is minimal, but after 2-3 days water from the water-saturated seam begins to penetrate deep into the surrounding rocks. Roof bolting significantly reduces these processes, the using of a scheme with 5-9 roof bolts re-strains the movement of water and, most importantly, practically isolates the roadway from water-saturated rocks. Scientific novelty. For the first time, a numerical model has been created and the calculations have been completed for roadways supported with 1-9 roof bolts in conditions of intensive inflows over time from the moment of its building. Practical significance. Research and calculations make it possible to obtain a significant economic effect due to the setting of the optimal number of roof bolts and the reduction of the use of materials for supporting the roadway and, at the same time, to prevent water inflows and increase the stability of road-ways.

Purpose. Improving the safety of rescuers during the performance of assigned tasks by determining the risks of injury and choosing directions for injury prevention. Methodology. The work used a complex research method, which includes an analysis of literary sources, a review of accidents in the units of the State Emergency Service, and an assessment of the risks of injury to rescuers. Results. As a result of the review of literary sources, the possibilities of risk assessment during the performance of tasks as assigned have been analyzed. It was decided to assess the risks of injury to personnel as a result of multiplying the probability of an event by its consequence. An assessment of the risks of injury to rescuers during the dismantling of the rubble of building structures has been carried out using a risk assessment matrix. The result of the identification of hazards, assessment of the probability and severity of the consequences is a quantitative assessment of the risk of occurrence of dangerous events during the liquidation of the consequences of the collapse of building structures, demolition of rubble. Indicators of risk assessment for certain types of hazards, which are more than a certain value, require a review of the existing ones and the adoption of additional measures to reduce injuries. The method of risk assessment, which consists of determining the zone of damage to people, is more informative when performing tasks as assigned by rescuers, which is the direction of further research. Risk assessment information can be used by unit managers and rescue managers to make decisions about the use of measures and means of reducing the impact of hazards on personnel. Scientific novelty of the obtained results lies in the fact that for the first time, for the conditions of emergency and rescue operations, an assessment of the risks of injury to rescuers has been carried out using a risk matrix. Practical significance of the obtained results lies in the possibility of using the principles and approaches to the assessment of the risks of injury to rescuers during emergency rescue operations and the development of measures to reduce injuries.

Aim. To study the features of the course of pregnancy, childbirth and the postpartum period in patients with iron deficiency anemia (IDA) with and without the use of iron supplements. Design. Retrospective case-control study. Materials and methods. A clinical and statistical analysis of exchange charts and birth histories of women was carried out at the clinical sites of the Department of Obstetrics and Gynecology with the course of perinatology of the Medical Institute of the Patrice Lumumba People's Friendship University of Russia. Pregnant women with IDA (n = 80) were divided into two groups: the 1st (n = 30) included patients who did not take iron supplements, the 2nd (n = 50) included women who received iron supplements after the diagnosis of IDA. Anthropometric, anamnestic, clinical and laboratory data of patients, features of the course of pregnancy, childbirth and the postpartum period were studied. Results. In patients of the 2nd group at the time of detection of IDA, lower levels of hemoglobin, erythrocytes and hematocrit were detected. However, against the background of timely initiation of iron supplementation, women in this group showed statistically significantly better indicators compared to patients who refused to take anti-anemic therapy: lower levels of blood loss during childbirth (p < 0.05), lower odds of hypotonic bleeding (odds ratio (OR) = 4.246; 95% confidence interval (CI) — 1.370–13.155) and obstetric perineal trauma (OR = 4.529; 95% CI — 1.707–12.018), Conclusion. The course of pregnancy, childbirth and the postpartum period in patients with IDA depends on timely treatment. Prescribing iron supplements for IDA in pregnant women helps reduce the frequency of threatened premature births, reduce the risks of pathological blood loss, uterine hypotension during childbirth and in the early postpartum period, as well as obstetric perineal trauma. The elasticity of tissues, in particular the perineum, in women with IDA after the use of iron supplements and normalization of hemoglobin levels corresponds to normal parameters, in contrast to postpartum women who did not receive iron supplements. Key words: iron deficiency anemia, pregnancy, childbirth, complications.

Diabetes and related complications such as hypertension are considered major public health issues throughout the world as they are the most important causes of death and disability and cause huge economic implications for both patients and the public health system. Sufficient management of these complications along with novel patient education and self-care strategies are documented as ideal approaches able to postpone the onset of morbidity and disability and thereby delay the onset of preventable costs. However, contradictions regarding the efficacy of the studied self-care strategies are mentioned, thereby the current study aimed to review self-care strategies as a preventive approach to disease management and improving clinical outcomes in patients with diabetes and hypertension. The findings revealed that self-care through patient education with nursing support can improve medication adherence and lifestyle. However, clinical outcomes have revealed relative inconsistencies that require further studies.
Humanitarian demining: How can UAVs and Internet of Things help?
Authors: Hutsul Taras , Tkach Vladyslav , Khobzei Mykola
Published: February 2024

The history of active mine use spans nearly two centuries. In this relatively short historical period, mines have become a global problem. Explosive objects and mines, remnants of wars and military conflicts, continue to pose a threat to people residing in these areas for a long time. As of the beginning of 2023, the State Emergency Service of Ukraine reported that approximately 40% of the territory (over 250,000 km2) had been mined. In terms of the extent of mined land, the United Nations classifies Ukraine among the most heavily mined countries. The scale of mine contamination surpasses countries where military conflicts have lasted for decades. The invention and improvement of mines have contributed to the development of methods to counter them. Today, more than fifty different methods and their modifications are known, but none guarantee a 100% success rate, underscoring the relevance of further scientific research. The creation and use of unmanned aerial vehicles (UAVs) have been a significant breakthrough in the field of intellectual achievements. Innovations manifest in all aspects, from modern composite materials to state-of-the-art navigation equipment and software. UAVs are actively deployed in various areas of human activity, demonstrating excellent results. The primary advantage of UAVs in humanitarian demining is the safety they provide, allowing individuals to operate in hazardous conditions beyond physiological and psychophysiological capabilities. The Internet of Things (IoT) is a relatively new combination of information and telecommunications technologies whose popularity is rapidly growing, opening up previously unexplored possibilities for practical applications. UAV and IoT technologies do not fall into the traditional classification of humanitarian demining methods. However, they serve as a connecting link for implementing, based on them or with their direct participation, other technological solutions (including geoinformation system (GIS), neural networks, artificial intelligence, Big Data, etc.). The prospects of implementing 5G communication networks in Ukraine will enhance spatial accuracy when combining both technologies, which is especially crucial for humanitarian demining. The recent advancements in communication technologies, such as 5G, and programs like the IoT, play a crucial role in aerial communication using UAVs. Depending on the application and operational region, UAVs have also been utilized to enhance coverage and throughput in 5G wireless communication. In such cases, UAVs act as intermediate nodes or flying base stations. This helps conduct operations in remote and challenging-to-reach locations. The idea of integrating cloud computing with UAVs enhances their role by providing additional computational capabilities.
Implementing the Search Algorithm of the Correlation Interferometer Direction Finder through the GNU Radio Software Platform
Authors: Polikarovskykh Oleksiy , Hula Ihor
Published: February 2024

In the realm of modern radio equipment development, the integration of Software Defined Radio (SDR) systems, encompassing both software and hardware components, has become widespread. SDR systems, particularly, find applications in the creation of direction finders for radio signal sources. The effectiveness of direction finding and the identification of radio radiation sources largely hinge on the technical specifications of the equipment. For contemporary systems aimed at detecting the location of radio radiation sources, direction finders based on a correlation interferometer prove to be highly suitable. These direction finders excel in performing direction finding for a wide array of radio signals, capable of recognizing broadband modulated signals. They can simultaneously process and identify several signals within a single frequency channel, originating either from a singular source of radio signals (coherent) or from multiple sources (incoherent). SDR technology enables programmable reconfiguration of a radio receiver through software. Such receivers boast a broadband radio frequency component with a significant dynamic range, a high-speed Analog-to-Digital Converter (ADC) path, a robust signal processor, and a specialized digital filtering path. SDR receivers are adaptable to signals of various standards and frequencies, depending on the specific tasks at hand. The GNU RADIO software platform stands out as the most flexible open-source software platform for SDR systems. This article delves into the utilization of the GNU RADIO software platform to implement the search algorithm for the direction finder of the correlation interferometer. The Ettus USRP N210 SDR platform was selected for implementing the direction finder using the correlation interferometer algorithm. This study introduces a two-channel software-controlled model of the direction finder, operating according to the correlation interferometer algorithm. The measurement results for the placement angle of radio signal sources yielded an individual absolute error ranging from 2 to 4 degrees, with an average absolute error of about 3 degrees. These results are quite commendable for such mobile two-channel systems. While systems with four or more channels boast higher accuracy, they tend to have lower economic feasibility.
Periodicity of Timeseries Generated by Logistic Map. Part I
Authors: Krulikovskyi Oleh , Haliuk Serhii
Published: February 2024

In the paper, the periodicity of pseudo-chaotic implementations in fixed-point calculations is studied using the example of a logistic equation. It was established that with 32-bit represented numbers (three bits - the whole part, 29 bits - the fractional part), the maximum length of the observed cycle is L_(max )< 2^14 iterations, and the space of possible states of the chaotic system after the completion of the transition process is limited S≈2^14 different numbers. Histograms of the duration of transient processes preceding the exit of the trajectory into a cyclic orbit are constructed. It was found that the maximum durations of the transition process do not exceed (2Lmax, 4Lmax). The paper also demonstrates and substantiates the expediency of using a dynamic threshold when forming binary sequences based on chaotic numbers using the threshold method. It is shown that the criterion for the balance of the binary representation of chaotic sequences enables the optimal choice of the number of high-order bits that must be discarded in order to obtain a uniform distribution. Approaches to increase the cyclicity of period of digital implementations of chaotic systems are analyzed. It is shown that the period of the external disturbance must be coordinated with the durations of the cycles observed in the chaotic system. The results of the work show the limitations of chaotic systems, which must be correctly taken into account when using them in cryptography.
