Published: January 2025

Inverse problem on recovering the coefficient of the right-hand side for a pseudoparabolic equation with a Caputo fractional derivative is studied. Overdetermination condition of the inverse problem is given in integral form. Existence and uniqueness theorems are proved for regular solutions (i.e., having all Sobolev generalized derivatives entering the equation) for a pseudoparabolic equation with the Caputo fractional derivative. Also, we propose an algorithm for numerical solution of the considered inverse problem. Numerical experiments are carried out for a one-dimensional problem, illustrating the obtained theoretical results. Inverse problems with fractional derivatives belong to the class of problems that are associated with determining unknown parameters or functions in mathematical models described by equations with fractional derivatives. Such problems arise in various applications where models with fractional derivatives are used, for example, in mechanics, heat conductivity, biology, finance and other areas.

Published: January 2025

This article deals with the "dynamics" of a rod system (a two-support beam with two cantilevers) with three point masses located along its length that simulate the distributed mass of the structure under the action of a vibratory dynamic load applied to the corresponding mass; this load models the kinematic disturbance that occurs in the chassis structure of vehicles when they move along uneven road surfaces.

Dynamic forces and displacements were obtained by an accurate analytical method of forces based on modal and vibration analysis of the structure operation. Unit and load coefficients of canonical equations were determined by the Mohr formula using the Vereshchagin rule.

A comparative analysis of the parameters of the beam stress-strain state was carried out for absolutely rigid and elastic-pliable support points of the chassis structure.

As a result of the study, the necessary unit and final moment and deflection diagrams were presented. For the comparative analysis of the results of dynamic and static calculations, the values of dynamic coefficients for bending moments in characteristic nodes along the beam length were calculated.

Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Mansurova Madina , Rakhimova Diana
Published: January 2025

Morphological analysis is a crucial task in Natural Language Processing (NLP) that greatly contributes to enhancing the performance of large language models (LLMs). Although NLP technologies have seen rapid advancements in recent years, the creation of efficient morphological analysis algorithms for morphologically complex languages, such as Kazakh, continues to be a significant challenge. This research focuses on designing a morphological analysis algorithm for the Kazakh language, specifically optimized for integration with LLMs. The study will address the following tasks: data corpus collection and processing, selection and adaptation of suitable algorithms, and model training and evaluation. This paper delivers a detailed exploration of using deep learning models for the morphological analysis of the Kazakh language, specifically highlighting Recurrent Neural Networks (RNN) and Transformer models. Because of Kazakh is an agglutinative language, where word formation is achieved by attaching multiple suffixes and preffixes, the task of morphological analysis poses 25 unique challenges for computational models. The performance of Recurrent Neural Networks (RNNs) is evaluated, including those with LSTM and GRU enhancements, in comparison with Transformer models, focusing on their capability to analyze the complex morphology of Kazakh. The results outline the benefits and limitations of each approach for processing agglutinative languages, indicating that RNNs are often more effective for Kazakh morphological analysis, whereas Transformer models may require additional fine-tuning to achieve optimal results with such languages.

They are generalized as a set of laws, theories and other ideas and views. Later, this knowledge is part of the digital data needed to solve other tasks or clarify the previous one. In the past five years, the number of participants in the web-based cyber system has increased dramatically, but cyber security in cyberspace and security on the Internet have become increasingly difficult for Internet users and service providers. A functioning table-based authentication modeling is proposed to protect personal and confidential information of cyber system participants and networks in cyberspace from unauthorized access and to ensure cyber security. Social engineering and low complexity password cracking has been the cause of serious research and discussion in the field of cyber security. In this research, it is highly relevant to carry out modeling and synthesis of authentication in effective data storage and network security in cyberspace. In this work, the authentication procedure, which is one of the main components of cyber security in cyberspace, is modeled on the basis of a functional table. The attributes used in the cyber system are grouped, and research, analysis and experiments are conducted with models for the grouped parts. The purpose of this study is to show that safety increases with the number of attributes and decreases with the chance of repeating the wrong sequence of symptoms.

Published: January 2025

This paper discusses the use of the Lattice Boltzmann equations method with free energy based on the phase field approach and implemented in the D3Q27 scheme for modeling the dynamics of a three-component fluid flow in a three-dimensional cavity. Based on this method, a program has been created and it has been verified using a test problem that includes modeling the separation of a ternary liquid mixture. The results demonstrate the dependence of the mixture separation on time, the influence of surface tension and gravity. For example, at a high surface tension, the separation of the components occurs faster. Data on the average kinetic energy of the flow and the rate of energy dissipation under various conditions are also presented. In addition, an analysis of
the performance of the developed software is performed, including a comparison of the serial and parallel versions of the program. Particular attention is paid to the physical aspects of the model: the transition regions between the components are described using a phase parameter changing according to the Cahn-Hilliard equation. The method allows one to model complex structures and predict the time it takes for the system to reach a stable state. The results confirm the correctness and efficiency of the proposed approach for studying the dynamics of multicomponent fluids

Published: January 2025

The choice of future profession is an important stage in the life of every high school student. Changes in the labor market transform models and methods of career selection which lead to changes in the professional preferences of young people. Throughout the career decision-making process, high school students may encounter conflicts between their interests, personal plans, and external circumstances. The article provides insights from a sociological study conducted among high school students. The study aims to examine the process of forming professional preferences of high school students. The sample size is 558 high school students. The socio-demographic structure of the respondents covers all important characteristics such as gender, type of school, nationality, and place of residence. According to the re-sults obtained, the majority of students have made some degree of determination regarding their profes-sional choice. The influence of career guidance work is evident in making decisions about future profes-sions. High school students who independently undergo career guidance activities show comparatively high decisiveness in comparison with high school students who are limited to career guidance activities within the school. Most high school students have seen changes in their professional preferences over the past three years, largely influenced by shifts in the labor market and guidance from parents, teachers. The data obtained can be used to optimize the organization of career guidance work in schools and to forecast the professional choices of school youth. The theoretical significance is associated with a deeper understanding of the process of forming professional preferences of high school students, taking into account various factors and decision-making about profession choice.

Distrust in the relationship between the citizen and the state leads to the dominance of manipulative-gaming interaction, which hinders both the development of civic identity and the establishment of partnerships between the citizen and the state. The aim of the article is a further conceptualization the doctrine of healthy and deformed relations between the individual and the state (in particular, analysis of the manipulative-gaming interaction between the citizen and the state. The theoretical model of “civic games” presented earlier is complemented by the concept of symmetrical and asymmetrical games prac-ticed in the relations between the individual and the state. This concept is substantiated by the descrip-tion of games initiated by the state: a game that is a “mirror image” of the civic game “Parasite”, as well as the asymmetrical game “Fighting Corruption”.The scientific value of the article is related to the application of the doctrine of transactional analysis to the relations between the citizen and the state; its practical value lies in the disclosure of forms of manipulative- gaming interaction, which opens up the possibility of finding ways to replace it with rational partnerships. Eric Berne’s transactional analysis and the self-agency’s approach were used as the methodological basis for our research. Conclusion: manipulative-gaming interaction replace a healthy relationship between the individual and the state. It expresses itself in the so-called games (in Berne’s understanding), which are a surrogate for healthy relationships and are aimed at achieving a psychological (political) benefits that imitates the solution of existing problems. The author analyzes a pair of symmetrical games – “Parasite” and “Give me everything for your own benefit” – as well as an asymmetrical game initiated by the state – “Fighting Corruption”.

A new system to the spectroscopy analysis with multiple X-ray of free electron laser
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Khalil Al-Aish Thair Abdulkareem , Amjed Kamil Hanady
Published: January 2025

The primary goal of this paper is the possibility of improving spectroscopy analysis using a new mechanism that has the ability to detect small crystalline defects and the fast transitions that occur within electronic states, which contributes significantly to the development of various fields and applications of scientific knowledge. The working mechanism is summed up by obtaining two laser pulses with specific specifications within the x-ray range, by creating an executive program (SAMXFEL) using the MATLAB program for the purpose of simulation. This system allows the investigation of rapid changes in the structure of matter. By analyzing the simulation results, two pulses of electron lasers were obtained with wavelengths ranging from (0.316535, 0.114399) nm and powers (927686, 927683) watts, in addition to pulse durations within (1.05512, 0.38133) atto-seconds that ensures that the target material is protected from damage. The proposed system in this paper is mainly based on the spectral and spatial separation of the two pulses to interpret the scattered and diffracted X-rays. The spatial separation allows multiple X-ray pulses to be emitted from different angles of the sample. X-ray diffractography using multiple simultaneous pulses from different angles becomes possible without loss of photon energy generated by the spectrometer.
Extraction of the radii of 9-Be, 10-B and 11-B nuclei in the approximation of the strongly absorbing nucleus model in elastic scattering reactions of deuterons
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Dyachkov Vyacheslav
Published: January 2025

To study the cluster states of light nuclei, in this work, the radii of 9Be, 10B and 11B nuclei were calculated using elastic scattering of deuterons with energies from 11 MeV to 28 MeV. From the oscillations of Fraunhofer-type nuclear diffraction patterns of experimental angular distributions of differential cross sections of elastically scattered deuterons on target nuclei, the free parameters of the complex angular momentum method were determined using fits to the single-valued minimum Pearson values. Moreover, the array of experimental data points was not always unambiguous, and this led to difficulties in the quality of fitting free parameters, which affected the results of radius calculations. The results of the radii are presented in the paper, the values of which were compared with the values of the world literature data. The obtained calculated values of the radii of nuclei for 9Be are in satisfactory agreement with the exception of some values. For 10B and 11B, there is a systematic excess of the obtained radii over the literature values. It is possible that such excess is due to the fact that when calculating the radii of the nuclei under study, the structure of the deuterons and their own radius, which increases the radius of interaction, were not taken into account.

It can be implemented via FPGA with a fast ADC and digital algorithm or a microcontroller with a peak detector circuit using an analog electrical circuit. MCA is widely applied in field work, nuclear medicine, and accelerator experiments. This work focuses on developing a lowcost alpha and gamma spectrometric system for experimental physics and field work, such as recording radiation and monitoring nuclear facility surroundings. Modern microcircuits, with small size and low power consumption, enable simpler and cheaper analog signal processing circuits that process signals in real-time without digital conversion delays. The spectrometric amplifier (SA) and peak detector (PD) were modeled and prototyped. A Python-based real-time data acquisition program was developed. Signals are recorded on the STM32F407 microcontroller’s ADC and transmitted via USB to a PC. An experiment obtaining the Ra226 alpha source spectrum verified the MCA’s functionality.

Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Abdullayev Jo`shqin , Sapaev Ibrokhim
Published: January 2025

This study provides a detailed analysis of the temperature-dependent electrophysical properties and current-voltage (I-V) characteristics of p-n junction structures based on Silicon (Si) and Gallium Arsenide (GaAs). The investigation spans a temperature range of 0–1000 K, examining key parameters such as bandgap, mobility, intrinsic carrier concentration, and I-V characteristics. Advanced modeling and calibration techniques were employed to reveal intricate thermal dependencies of these parameters and their impact on device behavior. The results demonstrate that recombination currents dominate at low forward biases (0.1–0.3 V), characterized by an ideality factor near 2, while diffusion currents prevail between 0.3–0.7 V, with an ideality factor approaching 1. At higher voltages, high-injection conditions emerge. In Si, diffusion mechanisms dominate from 0.4–0.7 V, while in GaAs, recombination remains the primary mechanism up to 1.2 V. These findings are corroborated by semi-logarithmic I-V curves, illustrating the distinct transitions between current mechanisms. This comprehensive study highlights the robustness of the proposed models in accurately capturing the temperature-dependent behavior of these materials. The insights gained offer valuable implications for optimizing p-n junction-based devices across a wide temperature range. Future research will extend these models to explore more advanced semiconductor structures and operational scenarios.

Published: January 2025

This study investigates the mechanisms and patterns of crevice corrosion in heat exchangers made from 06KhN28MDT alloy (analogous to AISI 904L steel) in model water systems of industrial enterprises. Using mathematical models, the relationship between activation potentials (Ecrev), repassivation potentials (Erep), and free corrosion potentials (Ecor) with the alloy’s chemical composition and structural components was established. It was found that Ecrev shifted positively with increasing levels of Mn, Cr, Cu and dg (mean austenite grain diameter), and decreasing levels of C, Si, Ni, Ti, Mo, VS (sulfide volume), and VN (titanium nitride volume). Cr, Mo, and dg were identified as having the most significant influence on Ecrev, Erep and Ecor. The study also highlights the importance of chromium in improving the protective properties of the oxide film, and the reduction of local corrosion damage near titanium carbonitrides intersecting austenite grain boundaries. The study concludes that the alloy’s resistance to crevice corrosion in recycled water systems improves with higher concentrations of Cr, Mo, and dg. The mathematical models developed in this research can be applied to predict the corrosion resistance of heat exchangers made from 06KhN28MDT alloy in industrial water systems.

Authors: Karim Abbas Ibrakhim
Published: January 2025

The dielectric barrier discharge (DBD) plasma is one of the branches of plasma produced at atmospheric pressure. It is easy to use in the laboratory, where the dielectric barrier discharge was built from a copper electrode with a glass insulator in front of one of the electrodes. The plasma was generated between the two electrodes at a high applied voltage ranging between (5-9) kV using a high voltage power supply and at a (7) kHz frequency. To perform the spectral characterization of the plasma produced by the dielectric barrier discharge (DBD) system and calculate the plasma parameters, a gradually increasing voltage (5-9) kV was used with a fixed frequency of (7) kHz in the first case, and in the other case, the frequency was changed (5-9) kHz with a constant applied voltage of (8) kV. The results showed that the increased applied voltage and frequency value led to an increase in the spectral intensity of (N2) of the plasma generated between the two electrodes, ranging from (296.44 - 715) nm. As well as an increase in the plasma electron temperature (Te) (0.895-1.436) eV and (0.922-0.522) eV, and the resulting plasma number density (ne) (5.485-9.541) x1016 cm-3 and (4.856-8.090) x1016 cm-3 in both cases, respectively, as well as the rest of the other plasma parameters.

Research on the Effect of Microplastics on Phosphorus in Soil and Water Environment
Authors: Bai Xiaomei , Zhang Zhen , Yang Qi , Qian Xiaoyan
Published: January 2025

Microplastics are a kind of emerging pollutants that are very widely distributed in soil and water. Phosphorus in soil and water often exceeds the standard due to phosphorus fertilizer. This paper summarizes the interaction of microplastics on phosphorus in water and soil from the aspects of aging, particle size, and species of microplastics. The results show that phosphorus adsorption of microplastics is related to the particle size and type of microplastics. The larger the particle size of the microplastics, the lower the adsorption capacity of phosphorus. Aging microplastics can improve the adsorption capacity of microplastics. After entering the water and soil environment, they may combine with phosphorus to form complexes, thus changing the migration behavior of phosphorus. Microplastics can be used as the carrier of phosphorus, promoting the migration of phosphorus in the soil and water environment under the action of water flow and wind power, so that the pollution range of phosphorus is expanded. Microplastics may affect the chemical form transformation of phosphorus in the soil and water environment. Due to the different types of microplastics, the adsorption intensity of phosphorus is also different.

Authors: Peng Jian
Published: January 2025

The strategic integration of “new industrialization” between Shenzhen and Hong Kong has shown a positive trend. Based on their respective comparative advantages, the two regions have established an orderly industrial division system. The deep integration of Shenzhen’s manufacturing industry with Hong Kong’s service industry has jointly promoted the prosperous development of the regional economy. In the Lok Ma Chau Loop area, the Shenzhen-Hong Kong Science and Technology Innovation Cooperation Zone is thriving, with a series of strategic emerging industrial projects successively landing, serving as a model for scientific and technological innovation cooperation between the two regions. Meanwhile, as an important platform for Shenzhen-Hong Kong cooperation, the Qianhai Shenzhen-Hong Kong Modern Service Industry Cooperation Zone has attracted a large number of Hong Kong-funded enterprises, becoming the forefront of economic interaction between Shenzhen and Hong Kong. However, while the strategic integration of “new industrialization” between Shenzhen and Hong Kong has achieved significant results, it also faces numerous challenges. Firstly, there is still considerable room for improvement in the alignment of systems and standards. Shenzhen and Hong Kong have significant differences in their economic, legal, and administrative systems, lacking a unified coordination mechanism and planning layout, which has led to a slow process of optimizing resource allocation. Secondly, Shenzhen faces “bottleneck” key technology challenges in its industrial development, with the lack of core technological breakthroughs becoming a bottleneck restricting industrial upgrading. Hong Kong, on the other hand, faces issues of industrial structural hollowing-out and simplification, with a fragile economic system due to the lack of manufacturing support. This paper aims to delve deeply into the current situation and challenges of the strategic integration of “new industrialization” between Shenzhen and Hong Kong, and by analyzing the advantages and disadvantages of cooperation between the two regions, proposes a development path for jointly building a world-class strategic industrial cluster.
