Munakahat education specifically for Madrasah student, the art of persuasive discourse practiced in South Asian and Middle Eastern traditions, has long captivated listeners with its intricate arguments and passionate delivery. However, traditional pedagogy often relies on static texts and rote memorization, failing to capture the dynamism and persuasiveness inherent in live debate fully. This research proposes a transformative approach: reimagining Munakhat education through immersive role-playing in one Madrasah in Indonesia. By merging text-based learning with interactive digital environments, this study explores the potential of virtual reality (VR) technology to foster deeper engagement and mastery of Munakhat skills. Participants practice Munakahat to enter captivating historical scenarios, embodying renowned Munakhat debaters of the past. Within these qualitative immersive settings, they will engage in real-time debates, formulate persuasive arguments, and hone their rhetorical skills in a context miming the charged atmosphere of actual Munakhat competitions. Through this innovative approach, Munakhat education transcends the confines of static texts and enters the vibrant realm of virtual theater. By empowering learners to step into the shoes of historical masters, this research reimagines Munakhat education as a dynamic and immersive journey, igniting a passion for persuasive discourse and cultural understanding.

Mead is a fermented drink with honey as the main ingredient, being called melomel when fruits or grains are added. In this work, the objective was to evaluate the physical-chemical parameters and the antioxidant potential of mead produced with the addition of coffee. Meads were made in a process similar to wine making, involving the operations of preparing the pre-inoculum, the must, yeast inoculation, fermentation and packaging. The meads produced with and without the addition of coffee were subjected to physical-chemical analyzes (moisture, acidity, pH, alcoholic content, reducing sugars, soluble solids (ºBx), ash) and the antioxidant potential (phenolic compounds and total flavonoids, DPPH , ABTS and FRAP). It was observed that for the parameters of pH (3.41), ash (0.04%) and reducing sugar (107.71 g L-1) the mead with coffee obtained higher values compared to the control drink without the addition of the adjunct coffee, which in turn demonstrated higher performance in the moisture (88.26%) and acidity (65.7 mEq L-1, 4.9 g of tartaric acid L-1) analyses. When related to the alcohol content of the drinks, both showed the same significantly value of 11.62% (without coffee) and 13.53% (with coffee). Regarding the properties of phenolic compounds and total flavonoids, the mead with coffee presented higher levels (305.85 mg GA100 mL-1), flavonoids (33.47 mg Q 100 mL-1), DPPH (153.01 mg T  100 mL-1) and FRAP (1236.08 µmol Fe(II) 1000 mL-1). The traditional drink presented ABTS as the best antioxidant activity with 245.67 mg T 100 mL-1. Coffee additives significantly influenced the beverage's physicochemical and bioactive characteristics, promoting its antioxidant potential and functional performance.

Coping with Negative News: Emotional Experience of Doomscrolling
Authors: Kazun Anastasia , Malygina Natalia
Published: December 2024

The majority of news encountered in media spaces tends to be negative. At the same time, the flow of information in the modern world is increasing, and series of successive crises prompting heightened attention to such content. There is such a phenomenon as doomscrolling. This study explores how doomscrollers describe their emotional experience of consuming news and strategies for managing negative emotions. Drawing upon empirical data from 47 interviews with doomscrollers conducted between late 2022 and early 2023. Informants associate negative news consumption with emotions such as anxiety (egotropic and sociotropic), helplessness/powerlessness (low external political efficacy and inability to control one's own life), apathy, and anger. Emotional experiences are often described using medicalized and psychotherapeutic vocabulary. Doomscrollers refer to their emotions as a form of illness, manifesting in the use of specialized terms, references to attempts at regulation with the help of healthcare professionals, and emphasis on the physical health consequences of news consumption. The coping strategies for dealing with these emotions are diverse. Informants may attempt to change their media consumption style by limiting their attention to negative news. At the same time, doomscrollers who maintain a high level of news consumption engage in active discussion and collective emotional experiences and may shift their attention to other daily activities. However, the practices of doomscrollers and the meanings they ascribe to their experiences are highly variable and diverse.
SOCIAL INTERACTION AND POLITICAL TRANSFORMATION OF WAHHABI DA'WAH IN LOMBOK
Authors: Nazar Naamy  , Khairul Aiman Wan Mokhtar Wan
Published: December 2024

This article will discuss the social interaction and political transformation of Wahabi da'wah groups in the Sasak community of Lombok NTB. This research question is how the interaction and political transformation of da'wah groups is how the process of political transformation of da'wah ideology towards resources and facilities of the Wahabi group. This research uses qualitative methods with a case study approach. The primary data in this study were taken from the field related to social interaction and ideology, religion, politics, da'wah, Wahabi groups towards resources and facilities. This study uses the point of view of George Caspar Homans' exchange theory. In social interactions that occur in society, basically there is always a process of exchange and rational calculation. What is exchanged here is cost, benefit, reward, punishment. The results of this study reveal that the interaction and political transformation of da'wah carried out by the Wahabi community no longer uses the ideology of da'wah, but the ideology of da'wah is just a sweetener or a way of camouflage in its political movement. While the political process of da'wah ideology has transformed towards resources and facilities, the decisive idea is that resources and facilities are distributed in Lombok society so that indirectly the Wahabi community gets rewards from people outside the Wahabi community, namely NU and NW. The reward in question is the transfer of ideology from NU and NW to Wahabi ideology. This is because the transformation of Wahhabism has moved towards the movement of resources and facilities

Future changes in sea surface temperature in the East Asian Marginal Seas projected by CMIP6 models
Authors: Jung Heeseok , Jung Euihyun , Jang Chan Joo
Published: December 2024

Future global-mean warming and its intermodel spreads have shown to be greater in the coupled model intercomparison project phase 6 (CMIP6) models than in the earlier generation CMIP5 models, mainly due to increases in both forcing and climate sensitivity. However, regional future changes and their intermodel difference in CMIP6 models have been less known. In this study, we assessed biases in the sea surface temperature (SST) simulated from 30 CMIP6 models and then estimated future SST changes in the near-term (2021-2040) and the mid-term(2041-2060) periods under the scenarios of the low (SSP1-2.6) and high (SSP5-8.5) emissions, by using selected eight CMIP6 models with superior performance in the East Asian Marginal Seas (EAMS). The SST changes in the EAMS are projected to be more pronounced in the mid-term compared to the near-term under global warming. SST is expected to increase by approximately 1.8°C under SSP1-2.6 and by 4.5°C under SSP5-8.5, with the largest increases occurring in the Yellow Sea, East Sea, and East China Sea. Seasonal variations are significant, with summer (August) warming projected to be about 50% greater than winter (February) warming under SSP5-8.5, primarily due to the shallowing of the summer mixed layer. Uncertainty in future SST projections is higher under SSP1-2.6 than SSP5-8.5 because of the stronger signal in the SSP5-8.5 scenario. Spatially, uncertainty is lower in the coastal areas and the Yellow Sea, but higher in the East Sea and the mixed water region (interfrontal zone) between the Kuroshio and Oyashio currents, where ocean currents contribute to greater intermodel variation. In conclusion, the projected future surface warming in the East Asian Marginal Seas (EAMS) is estimated to be approximately twice the global mean, indicating that EAMS is a climate change hotspot with a high level of vulnerability to future global warming.

Authors: Chernenko Serhii , Burnashev Vitalii
Published: December 2024

The article presents an algorithm for determining the orientation angles of an aircraft using data from two optical cameras and a gyroscope triad. The cost functions required for calculating roll, yaw, and pitch are described. A simulation of the algorithm's performance was conducted using real images, along with sequential correction of orientation angles based on the proposed approach. The algorithm takes into account errors from low-accuracy angular velocity sensors. Among the advantages of the method are its independence from the need to detect the horizon line and its low computational resource requirements for the navigation system.
Improving the accuracy of a platformless inertial navigation system for an aircraft during rapid roll rotation
Authors: Hyzhnyak E , Chernyak Mykola
Published: December 2024

The article addresses the problem of enhancing the accuracy of an autonomous strapdown inertial navigation system (SINS) for aircraft with rapid rotation about their longitudinal axis. This rapid rotation stabilizes the aircraft's position along the longitudinal axis while imposing strict requirements on the roll gyroscope's scale factor (SF) error in the SINS. This is essential to ensure that the roll angle error remains on par with the pitch and yaw angle errors.
A novel method for periodic correction of the roll gyroscope's SF within an autonomous SINS is proposed. The method utilizes signals from a single-axis indicator gyrostabilizer based on a microelectromechanical system (MEMS) gyroscope. The correction involves determining the numerical value of the roll gyroscope's SF error during flight and subsequently compensating for its influence on the roll angular velocity measurements.
The functional scheme of the method is presented, along with formulas for calculating the correction coefficient. The efficiency of the proposed approach in improving the accuracy of the SINS is evaluated using a typical inertial module and an indicator gyrostabilizer with a MEMS gyroscope as an example.
The method significantly enhances the accuracy of roll angular velocity and coordinate measurements in an autonomous SINS without requiring expensive precision gyroscopes.
Aeroelastic vibrations control system of an unmanned aircraft
Authors: Bondarenko Oleksander , Shkolnyi Vyacheslav
Published: December 2024

A control system that allows reducing the amplitude and time of aeroelastic oscillations of the wing of an unmanned aircraft by actively changing its shape is proposed. The shape change is achieved by the wing control surfaces. The control system contains a corrective link, which is synthesized by one of the known methods, in particular, logarithmic frequency characteristics. Semi-real-life modeling was carried out in applied mathematical and design software packages. Using the example of wing ailerons and a corrective link in the form of a PID controller, the effectiveness of the aeroelasticity control system was assessed. It is shown that by selecting the proportional and integral coefficients of the corrective link in the control system, it is possible to increase the critical flutter speed of the wing of an unmanned aircraft.

Scientific article summarization model with unbounded input length
Authors: Steblianko Oleksandr , Shymkovych Volodymyr , Kravets Peter , Novatskyi Anatolii , Shymkovych Lyubov
Published: December 2024

In recent years, the exponential growth of scientific literature has made it increasingly difficult for researchers and practitioners to keep up with new discoveries and developments in their fields. Thanks to this, text summarization has become one of the primary tasks of natural language processing. Abstractive summarization of long documents, such as scientific articles, requires large neural networks with high memory and computation requirements. Therefore, it is all the more important to find ways to increase the efficiency of long document summarization models.
The objects of this research are long document summarization transformer models and the Unlimiformer cross-attention modification. The article reviews the basic principles of transformer attention, which constitutes the primary computational expense in transformer models. More efficient self-attention approaches used for long document summarization models are described, such as the global+sliding window attention used by Longformer. The cross-attention mechanism of Unlimiformer, which allows a model to have unbounded input length, is described in detail. The objective of the study is the development and evaluation of a long document summarization model using the Unlimiformer modification. To achieve this goal, a Longformer Decoder-Encoder model pretrained on the arXiv dataset is modified with Unlimiformer cross-attention. This modification can be applied without additional model fine-tuning, avoiding the cost of further training a large sequence length model.
The developed model was evaluated on the arXiv dataset using the ROUGE-1, ROUGE-2 and ROUGE-L metrics. The developed model showed improved results compared to the baseline model, demonstrating the viability of using this approach to improve long document summarization models.
Software for collecting and analyzing metrics in highly loaded applications based on the Prometheus monitoring system
Authors: Stetsenko Inna , Myroniuk Anton
Published: December 2024

This paper emphasizes the importance of collecting metrics during application operation for early detection of potential problems. The undisputed leader in this area is the Prometheus monitoring system, which, combined with Grafana – a platform for visualizing collected data in numerous graphs – becomes an indispensable tool for programmers and site reliability engineers. However, the average value of a certain metric is often unrepresentative, because it does not reflect a comprehensive picture. Instead, collecting metrics in terms of various quantiles over a long period is useful to identify even single instabilities. Still, the use of standard tools in the Python ecosystem may require a lot of server resources and long preliminary analysis, which can be quite costly for businesses from a financial point of view. That is why the development of a new approach for collecting and analyzing metrics in highly loaded applications based on the Prometheus monitoring system is relevant.
The research aims to improve the efficiency of storing metrics across different quantiles, which will create additional opportunities for further analysis.
A review of existing approaches for calculating quantile values on large data sets was conducted. Their comparative characteristics in terms of speed and memory usage were also presented. The chosen method was adapted for use with the real-time data stream and implemented as a Python extension for the official Prometheus library. It opens up opportunities for comprehensive monitoring of highly loaded systems in terms of both server resource usage and the quantity and quality of collected useful data. This solution can be easily implemented on large projects requiring continuous tracking of various metrics to ensure stable and uninterrupted service operation.

Today, in the telecommunications industry, service is one of the fundamental concepts. Building a service architecture is a key stage in the service life cycle. Information systems of telecommunications providers are designed, implemented and supported by IT companies based on the End-to-End model. This requires the IT company to solve a number of complex problems. In these conditions, building a service architecture, implementing and providing a service are divided into subproblems. Solutions to subproblems must be integrated to determine the coordinated activities of both the IT company and the provider. In this case, it is necessary to take into account the goals of IT companies, providers and their customers in such a way that it is beneficial to all parties. One of such subproblems is the formation of service packages that the IT company offers to providers. The article proposes formal models for the subproblem of forming service packages that allow taking into account the interests of the IT company and providers. These are multi-criteria nonlinear mathematical programming models. To solve the subproblem of forming service packages, a two-stage algorithm and a modified version of the guided genetic algorithm are proposed. The use of these methods allows us to take into account the interests of the IT company and providers. Also, such important factors that affect the formation of packages as the base price of the service, service dependency, discount system, resource and other constraints of the IT company and providers are taken into account.
The two-stage algorithm at the first stage uses classical algorithms for solving the knapsack problem, and at the second stage implements a compromise scheme to improve the solution. The second of the proposed methods uses three types of tools in combination. The first tool controls the convergence of the genetic algorithm. The second tool determines the choice of the best solutions taking into account the features of the multi-criteria problem. The third tool allows to obtain the best solutions to the optimization problem with the simultaneous choice of a discount strategy. Experimental studies have confirmed the effectiveness of the proposed methods. Their ability to form the basis of the technology of forming service packages as a component of the platform for supporting the life cycle of services is also confirmed.

Authors: Beraudo Elisa , Oliinyk Yurii
Published: December 2024

The study focuses on the development and implementation of an automated system for scalping strategies in cryptocurrency markets. Scalping, a high-frequency trading strategy, aims to generate profits from small price fluctuations. The primary goal of the research is to create an automated trading bot that addresses critical issues such as latency, risk management, scalability, and reliability in real-world market conditions. To achieve this, the following objectives were defined: develop a novel scalping method, implement a software solution to integrate the method into an automated trading system, and evaluate its effectiveness through experimental testing.
The research methodology utilized technical indicators, including the Exponential Moving Average (EMA) and Volume Weighted Average Price (VWAP). Pseudocode was created to illustrate the decision-making process, incorporating key parameters such as smoothing factors, time periods, and thresholds for trade execution. The software architecture consists of modules: Binance exchange integration, data collection and management, strategy analysis, trade execution, and historical data storage. Technologies such as PostgreSQL, Redis, WebSocket, and Python libraries (Pandas, NumPy, TA-Lib) were employed to ensure the robustness and efficiency of the system.
Experiments were conducted using the BTC/USDT trading pair, known for its high liquidity and volatility. The system was tested on hardware featuring an Intel Core i7-10700K processor, 32 GB of RAM, and a 1 Gbps network connection. A comparative analysis between the scalping strategy and a trend-following strategy demonstrated the advantages of scalping in volatile markets. The scalping bot executed 15 trades (13 successful) within two hours, achieving a total profit of 120 USDT.
Performance metrics, including latency (15–50 ms), signal processing time, CPU utilization(5–55%), and memory usage (120–2100 MB), were measured. The results confirmed the system's modular architecture and its ability to scale linearly with increasing trading volumes.
The findings validate the effectiveness of the proposed method and the reliability of the developed system in real-world conditions. Future research may focus on optimizing algorithms to reduce resource consumption and integrating advanced risk management techniques to enhance performance.

Published: December 2024

The article is devoted to the study and application of modern tools for Continuous Integration and Continuous Deployment (CI/CD) in the educational field. Automating the processes of software deployment and testing is a relevant task for both improving the educational process and developing DevOps skills among students. Significant attention is given to studying the core principles of CI/CD, including automated testing, code quality monitoring, and integration with source code repositories.
Popular CI/CD platforms such as Jenkins, GitLab CI/CD, and GitHub Actions are utilized to automate the educational process and train students. These tools enable the creation and deployment of applications using Docker technologies, which allow real-world scenarios to be modeled. A significant emphasis is placed on the scalability and adaptability of solutions, which enhance the efficiency of resource usage.
A methodology for implementing CI/CD into an educational course is proposed, including integration with project management platforms and version control systems such as Git, with Gitea as an example. The main stages include setting up automated builds, testing, and deployment, which enable students to practice the principles of continuous integration and delivery. From the perspective of improving the efficiency of the educational process, the proposed methodology allows for the automation of assignment verification. The problems of Gitea and Jenkins integration are considered. A way for integrating these tools through locally installed Jenkins and Gitea with private code repositories has been proposed. Recommendations are provided for organizing the educational process through practical and laboratory work focused on real-world scenarios of software deployment and test automation.
The results of the study confirm the effective use of CI/CD tools for educational purposes, ensuring the development of competencies required for working in modern IT teams. The use of CI/CD increases awareness of cybersecurity and optimizes DevOps processes.
The Tragic Downfall and Peculiar Revival of Quaternions
Authors: Brezov Danail
Published: December 2024

On October 16th 1843 the prominent Irish mathematician Sir William Rowan Hamilton, in an inspired act of vandalism, carved his famous i2=j2=k2=ijk=−1 on the Brougham Bridge in Dublin, thus starting a major clash of ideas with the potential to change the course of history. Quaternions, as he called his invention, were quite useful in describing Newtonian mechanics, and as it turned out later - also quantum and relativistic phenomena, which were yet to be discovered in the next century. However, the scientific community did not embrace this new approach with enthusiasm: there was a battle to be fought and Hamilton failed to make a compelling case probably because he was standing alone at the time. Although Quaternions were soon to find useful applications in geometry and physics (with the works of Clifford, Cayley, Maxwell, Einstein, Pauli, and Dirac), the battle seemed lost a few decades after Hamilton’s death. But a century later computer algorithms turned the tides, and nowadays we witness a revived interest in the subject, prompted by technology.
