This study presents a Reinforcement Learning-based algorithm designed to optimise irrigation for Durio Zibethinus (i.e., durian) trees, aiming to maximise tree growth and reduce water usage. Traditional irrigation methods, as well as current machine learning models, often focus only on soil moisture and weather data, neglecting critical factors like actual tree growth. This study proposed a reinforcement learning irrigation (RL-Irr) algorithm incorporating tree growth stages, soil moisture, and weather conditions to determine precise irrigation needs. The algorithm was developed by calibrating the AQUACROP model using data from actual durian plantations where rain-fed irrigation (rain-fed) was practised. Daily irrigation volumes were calculated based on real-time soil moisture, weather forecasts, and weekly tree growth measurements. The reinforcement learning method was used to optimise irrigation schedules, with rewards based on soil moisture, tree growth, rainfall, and weather conditions. The algorithm was tested using AQUACROP simulations and compared against soil moisture balance irrigation (SMB-Irr) and rain-fed. The results showed that the RL-Irr reduced water use by up to 75 percent while maintaining tree growth. These findings suggest the algorithm could significantly improve water efficiency in durian farming, though real-world applications should consider potential model limitations.

Authors: Rao Sudesh , Kulkarni Sanjeev , Bhat Radhakrishna
Published: October 2024

The diagnosis of Diabetic Retinopathy (DR) demands a paradigm shift towards more accurate and efficient solutions to overcome vision impairment. Therefore, the current study introduces a new Modified Regularisation Long Short-term Memory (MR-LSTM) framework approach for DR diagnosis. The proposed framework leverages the power of deep learning and provides a dynamic and robust solution for the early detection of DR, which in turn preserves a patient’s vision. The proposed framework uses a DR Debrecen Dataset from the UCI database with 21 distinct features relevant to retinal health, and employs a series of data preprocessing steps, including data cleaning, normalisation, and transformation, to ensure data quality and compatibility. The MR-LSTM framework excels at capturing temporal dependencies in sequential retinal images, offering a unique advantage in understanding the progression of DR. The MR-LSTM framework is implemented using Python libraries, and the results are compared with those of other popular models. It is observed that the MR-LSTM framework outperforms other models and achieves an accuracy of 97.12 percent and an F1 Score of 98.49. Furthermore, the Receiver Operating Characteristic (ROC) curve reveals an area under the curve of 0.97, highlighting the exceptional ability to discriminate between positive and negative cases of the proposed framework. By revolutionising DR diagnosis with the proposed MR-LSTM framework, it can achieve accurate, timely, and accessible solutions in the fight against vision-threatening conditions.

Published: October 2024

Real-world data is continuously produced andcollected quickly; hence, mining association rules are used tofind relationships between item sets. One of these combinedrule mining techniques is Rare Association Rule Mining(RARM), a method that extracts rare, combined rules with lowsupport but high confidence from the database. Additionally,a large amount of time-sensitive data is created in many fields,and combining valid and outdated data leads to low efficiencyin extracting combined rules. This paper explores a miningmethod that increases rare, combined rules on time-sensitivedata to extract common and rare patterns in the database.The primary approach of the research proposes a new treestructure called ILC-tree, inspired by the LC-tree structurepublished in 2022. Specifically, our approach includes a newtree structure and a fast reconstruction method. The proposedapproach reduces execution time and memory consumptionby approximately 2 times compared to the old tree structure.

The article examines the strategic approaches of public authorities to the introduction of educational trajectories for social entrepreneurship. It analyses foreign experience in this field, in particular on the examples of Great Britain, the USA, Singapore, Germany, Spain, and the Netherlands. The possibilities of applying foreign experience in Ukraine, taking into account national specifics and existing challenges, such as the socio-economic situation, decentralisation reform, limited resources, and the need to adapt best practices, are outlined. Directions for improving the public administration of educational trajectories of social entrepreneurship are proposed. These directions include regulatory support, institutional support, financial and personnel support, intensification of international cooperation, and the introduction of a monitoring system. Each of these areas is considered in detail, and their importance for creating favourable conditions for the training of specialists in the field of social entrepreneurship is substantiated. The research is based on the analysis of literary sources, comparative analysis, induction, and analysis of statistical data. The necessity of a systematic approach to the public administration of educational trajectories of social entrepreneurship is substantiated, which involves the harmonisation of the efforts of state authorities and local self-government, a clear delineation of their powers and responsibilities, as well as the coordination of actions of various departments and institutions at all levels. The study aims to contribute to the formation of an effective ecosystem for the development of social entrepreneurship in Ukraine through the development of educational infrastructure and the training of qualified personnel using strategic approaches of public authorities. Particular attention is paid to the role of education as a key tool for the dissemination of ideas of social entrepreneurship and the formation of the necessary competencies. Mechanisms of public-private partnerships are considered to ensure effective interaction between public authorities, educational institutions, businesses, and non-governmental organisations. The need to establish specialised educational training centres and incubators for social entrepreneurship is emphasised. The article outlines the prospects for the implementation of the proposed strategic approaches and their potential impact on the development of social entrepreneurship in Ukraine.

Published: October 2024

The educational process and the acquisition of key competencies and skills during training ensure that vocational education and training (VET) students meet employers' requirements. Despite the state of war in Ukraine, the demand for workers in the labour market remains quite high. The purpose of the article is to analyse the relationship between some components of the educational process and learning conditions with the employment of VET graduates. For this, the results of the monitoring study of career trajectories of VET graduates were used, which was conducted by means of a survey during October-November 2023. The conducted analysis showed that among the surveyed graduates, who at the time of the survey worked in the profession acquired in a VET institution, the vast majority (87.4% of the respondents) used and constantly use the knowledge and skills they acquired during their studies in their work. The results of the factor analysis indicated that for graduates who were employed in their respective fields at the time of the survey, the most significant was the educational process (group classes, e-learning through electronic resources (textbooks), theoretical, practical, and individual classes, etc.), the components of which they had enough during their studies. Also, for the surveyed graduates, the connection between theory and practice and industrial training is important, which, according to their estimates, was very useful during their studies. However, the surveyed graduates did not consider the study conditions (such as the learning materials, the availability of necessary technical equipment, the condition of the facilities, the accommodation provided, the balanced nutrition, and the scholarship amount) to be significant. The direction of further research is conducting a survey of employers and VET graduates, which will allow a comprehensive assessment of the compliance of the graduates with the needs of the labour market and their professional implementation.

Published: October 2024

Emergencies in hospitals, including in-hospital cardiac arrest (IHCA), necessitate effective response systems for monitoring vital signs such as heart rate and oxygen saturation. This study aims to develop and evaluate a Heart Rate and Oxygen Saturation Internet of Things (HROS-IoT) system utilizing the MAX30102 sensor and ESP32 microcontroller for real-time health monitoring. The system transmits data to the Blynk application via WiFi, enabling remote monitoring. Testing involved comparing the HROS-IoT system's performance against the commercial LK87 oximeter in measuring heart rate and oxygen saturation before and after meals with five participants. Results indicated that the HROS-IoT system produced heart rate measurements with an average error of 5.2 BPM before meals and 11.3 BPM after meals. Oxygen saturation readings showed an average error of 1% before meals and after meals. Despite minor discrepancies influenced by individual physiological differences and environmental conditions, the HROS-IoT system consistently delivered reliable data. The system's real-time monitoring capability and remote data access enhance proactive health management in hospitals. This study demonstrates the potential of the HROS-IoT system to improve patient outcomes and safety, suggesting further refinements for better accuracy and integration into healthcare settings.

Authors: Wijayanto Febri , Santoso Banu
Published: October 2024

Penelitian ini bertujuan menganalisis kualitas layanan (QoS) pada routing loops antara Open Shortest Path First (OSPF) dan Enhanced Interior Gateway Routing Protocol (EIGRP) menggunakan Spanning Tree Protocol (STP) untuk mencegah loop dalam topologi jaringan. OSPF adalah protokol routing dinamis dengan algoritma link-state, sedangkan EIGRP adalah protokol hybrid yang menggabungkan algoritma link-state dan distance vector. Masalah utama pada protokol routing adalah routing loop, yang dapat menyebabkan kemacetan jaringan dan gangguan komunikasi. Penelitian ini menguji empat skenario routing pada IPv6. Hasilnya menunjukkan bahwa EIGRP tanpa STP memiliki throughput 93.973 Bytes dengan delay 0.147ms, sedangkan OSPF tanpa STP memiliki throughput 94.056 Bytes dengan delay 0.180ms. EIGRP dengan STP menghasilkan throughput 93.922 Bytes dengan delay 0.150ms, dan OSPF dengan STP menghasilkan throughput 94.056 Bytes. STP tidak meningkatkan throughput secara signifikan tetapi memperbaiki delay pada OSPF. Tidak ada paket yang hilang dalam semua skenario. Jitter terendah dimiliki oleh OSPF tanpa STP sebesar 0.011ms, sedangkan jitter tertinggi pada EIGRP dengan STP sebesar 0.0124ms. Penelitian ini menunjukkan bahwa pemilihan protokol routing dan penerapan STP memengaruhi kinerja jaringan IPv6 tergantung pada prioritas throughput atau delay.

Echo Location: Distances to Galactic Supernovae From ASAS-SN Light Echoes and 3D Dust Maps

Published: October 2024

Light echoes occur when light from a luminous transient is scattered by dust back into our line of sight with a time delay due to the extra propagation distance. We introduce a novel approach to estimating the distance to a source by combining light echoes with recent three-dimensional dust maps. We identify light echoes from the historical supernovae Cassiopeia A and SN 1572 (Tycho) in nearly a decade of imaging from the All-Sky Automated Survey for Supernovae (ASAS-SN). Using these light echoes, we find distances of 3.6±0.1 kpc and 3.2−0.2+0.1 kpc to Cas A and Tycho, respectively, which are generally consistent with previous estimates but are more precise. These distance uncertainties are primarily dominated by the low distance resolution of the 3D dust maps, which will likely improve in the future. The candidate single degenerate explosion donor stars B and G in Tycho are clearly foreground stars. Finally, the inferred reddening towards each SN agrees well with the intervening column density estimates from X-ray analyses of the remnants.
Analytical justification of the thermochemical interaction between blast reagents and carbon-containing products under the influence of magnetic fields
Authors: Lozynskyi V. H , Falshtynskyi V. S
Published: October 2024

Purpose. To justify and develop a model that describes the effect of magnetic treatment of blast reagents and carbon-containing products on the gasification process for predicting the intensification of gas formation. Methodology. The study involves theoretical modeling based on experimental data to investigate the influence of magnetic fields on the underground coal gasification process and co-gasification of coal and carbon-containing products. The Arrhenius equation was used to estimate the rate constants of gasification reactions in the temperature range of 800–1,000 °C. The effect of the magnetic field was incorporated by adjusting the activation energy (Ea). The results of analytical and experimental studies were processed using methods of computer and mathematical modeling. Findings. The results show that the application of magnetic fields significantly intensifies the gasification process of carbon containing products. Increasing the reactivity of the blast reagents, particularly water and oxygen, leads to a higher overall yield of combustible gases. The use of magnetic fields in the gasification process substantially increases the reaction rate (k) due to the reduction in activation energy (Ea), improving the overall efficiency of gasification. Originality. For the first time, an analytical model has been developed to describe the effect of magnetic treatment of blast reagents and carbon-containing products on the gasification process in the temperature range of 800–1,000 °C. The obtained reaction rates follow an exponential trend. The established and correlation-validated pattern shows the relationship between changes in the approximation coefficient (F ) and the change in the carbon fraction (C, %) during the magnetic treatment of blast components within the specified temperature range. Practical value. The results of this study can be applied to enhance the efficiency of industrial gasification processes, particularly underground coal gasification and co-gasification of coal and carbon-containing productss.

The safe parameters of recreational areas during their construction in the watered residual space of the quarry were established taking into account the physical and mechanical properties of embankments made of sand, loam, and crushed rock by determining the stability of their slopes. The obtained results are necessary for the implementation of project works on the development of technological schemes for the reclamation of the residual spaces of construction materials quarry for the recreational direction of post-mining. Originality. The influence of the height of the rock embankment formation on the stable angle of inclination of the watered slope was established, which allowed determining that with an increase in the aggregates embankment height from 20 to 80 m, the safe angle of the slope will decrease from 46 to 26°. It was determined that the lowest FOS indicator is 0.57 when using sand rocks for an embankment height of 80 m at a water content of 40 %. It was established that with partial flooding of the rock embankment by 45–50 % for sandy, loamy and rocky rocks, there is a significant decrease in the coefficient of the reserve of stability by 1.4–1.5 times, in contrast to the absence of water or complete flooding, which confirms the negative impact of partial flooding of embankments and reducing the stability of their slopes. Practical value. It was determined that when forming an embankment 20 m high from loamy rocks, the volume of reclamation works will be 1.34 times less compared to sandy rocks, but 1.02 times larger than rocky rocks. When the height of the embankment increases to 80 m, the volume of reclamation works when replacing loam with sand will increase to 1.87 and 1.12 times when using crushed stone. However, taking into account the market value of materials, when using loam, the cost of construction will decrease by 2.5 times compared to sandy rocks and 3.2 times – to crushed stone, with an embankment height of 20 m. When the embankment height increases to 80 m, the cost of materials will increase by 3.5 and 3.8 times when loamy rocks are replaced by sand or crushed stone, respectively.

Purpose. Developing a technology for managing cyber risks based on their improved classification by the level of impact on the occurrence of an extreme situation. Methodology. To achieve the goal, general scientific and special methods of cognition were used in the study: dialectical and systemic approaches, analysis and synthesis, logical generalization and grouping, structural-logical method, iterative approach, modeling, method of formal representations of uncertainty. Findings. A cyber risk management technology has been developed, consisting of four main stages: analysis of cyber threats (context establishment; security audit; formation of scenario concepts); scenario modeling (threat decomposition; scenario formation; setting criteria; setting probability estimates of concepts (variables); building a network architecture; formation of a private threat model; scenario analysis); risk assessment; object classification. The proposed approach to cybersecurity risk management provides vulnerability detection and risk assessment (risk potential) and simplifies the development of management solutions to prevent events affecting cybersecurity. Originality. The proposed technology differs from the existing ones by focusing on identifying those vulnerabilities and cyber threats that, according to their improved classification by the level of impact on the occurrence of an extreme situation, can lead to serious disruptions in the functioning of critical information infrastructure of the national economy. Practical value. The practical significance of the study lies in the fact that the proposed cyber risk management technology is one of the tools for preventing the realization of risks in cyberspace and the basis for strengthening the information security of economic entities in particular and the national economy as a whole.

Purpose. To determine the relationship between innovation and infrastructure to support entrepreneurship as factors of growth of economic opportunities, based on the results of empirical research. Methodology. The case method and modern tools of econometric research were used to create an economic-mathematical model that assesses the relationship between economic opportunities and indicators of economic innovation. The research is based on the results of the Gallup 75 Years Anniversary Survey on current and future economic opportunities, as well as Global Innovation Index (GII) indicators. Findings. Creating favorable conditions for doing business and developing entrepreneurship is critically important for the economic recovery of Ukraine. The high level of entrepreneurial activity among Ukrainians emphasizes the importance of the development of innovative infrastructure and business support. The developed models can be used to forecast the economic capabilities of the population, which will contribute to the return of citizens and the development of the national economy. Thus, innovations and an effective infrastructure to support entrepreneurship play a key role in ensuring sustainable economic growth and social well-being in Ukraine. The results of the study can become the basis for developing strategies for economic development and solving migration problems in the post-war period. Determinants of the growth of economic opportunities of the population (human capital) are determined. The suggested GII parameters most correlate to positive feedback on economic opportunities and growth over the next 25 years. Originality. For the first time, the relationship between economic opportunities, the development of innovations and the development of infrastructure at the enterprise has been empirically proven. Statistically significant predictors of current and future economic opportunities of the population are substantiated and relevant economic and mathematical models for their evaluation and forecasting are developed. Practical value. The results of the study are particularly relevant in the context of solving the migration crisis caused by Russia’s military aggression against Ukraine. The return of citizens who have left the country depends on the creation of favorable conditions for business and the development of entrepreneurship. The developed models can be used to forecast the economic opportunities of the population in different countries, which will allow effective management of migration processes and promote the development of national economies. This will ensure the creation of a favorable business environment, which is critical for sustainable economic growth and social well-being.
