Instagram Facebook, Twitter, the impact of publications in social networks of the International Kazakh‑Turkish university named after Khoja Ahmed Yasawi in the period from the beginning of 2022 to the beginning of 2025 on the formation of the image of the university is analyzed in detail using artificial intelligence (AI) tools. In the course of the study, such aspects as the influence of language and visual content on the image, the emotional coloring of publications (sentiment analysis), topic modeling and visual recognition (image recognition) are considered.

The content on social networks is systematically analyzed using AI-based Natural Language Processing (NLP), thematic modeling, sensory analysis and image recognition methods. As a result of the study, the image of the University in the digital information space, methods of communication with the audience and the effectiveness of content were determined.

Based on the results obtained in the article, specific recommendations are given to improve the digital communication strategy of the University. This work is a practical basis aimed at strengthening the image of universities in social networks and the effective use of AI tools.

In addition, the data obtained during the study were visualized and the dynamics of the content and the reaction of the audience were analyzed over time. The proposed methods form an innovative model for evaluating social network content and provide effective mechanisms for promoting the university brand.

2025-07-08T04:35:42+00:00

The Sobel operator is a gradient method used in edge detection. It determines the change in intensity (gradient) in the image, and also calculates changes in the horizontal (x) and vertical (y) directions of the image. And Canny edge detection is an advanced way of finding edges. Both methods are used to detect edges, but each has advantages and disadvantages. It follows several steps and aims to detect stable edges with minimal errors. This study aims to compare the performance of Sobel and Canny edge detection algorithms on different image datasets. Although the Sobel algorithm gave faster results in terms of processing time, the Canny algorithm showed superior performance in terms of accuracy and noise tolerance. In tests on natural, medical, and industrial images, the Canny algorithm provided higher accuracy and noise tolerance compared to Sobel. In terms of processing time, the Sobel algorithm gives faster results. The research results show that the Canny algorithm should be preferred in applications that require high accuracy and noise tolerance, and the Sobel algorithm in cases where fast processing time is important. These results provide key information to help select an appropriate edge detection algorithm in various application scenarios.

DEVELOPMENT OF SHAPE MEMORY ALLOYS USING HIGH ENERGY MILLING OF NITICU BASED POWDERS

2025-06-18T04:11:53+00:00

The paper presents the results of studies on the development of alloys with shape memory effect (SME) based on the NiTiCu system using the high-energy powder milling method. The aim of the study is to obtain microstructured materials with improved functional properties, such as high temperature stability, low phase transition hysteresis and increased cyclic durability. The high-energy milling method allows achieving a uniform distribution of components and the formation of a micro-sized structure, which contributes to the optimization of phase transformations and improvement of the mechanical properties of the alloys. The influence of milling parameters, such as processing time and impact energy, on the microstructure, phase composition and functional properties of the obtained materials were studied. The results demonstrate the promise of using high-energy milling to create NiTiCu alloys with improved performance characteristics, which opens up new possibilities for their application.

INFLUENCE OF TYPES OF MECHANOACTIVATION ON WC ALLOYS

2025-06-26T04:49:28+00:00

This article reviews studies on the effect of mechanical activation (MA) on tungsten carbide-based alloys. MA is widely used in the field of materials science and is aimed at changing the physicomechanical properties of additives in order to increase their reactivity. WC-based hard alloys are widely used in various industries, as they have excellent mechanical properties, exceptional wear resistance, high strength and thermal stability. In this regard, tungsten carbide-based hard alloys are most suitable for the production of cutting tools. In addition, the article provides an analysis of complex types of mechanical activation used in various studies. The effect of types of mechanical activation on the physicomechanical properties of the obtained alloys is also considered. An analysis of the optimal parameters for obtaining hard alloys from powder samples pre-mechanically activated by the spark plasma sintering (SPS) method was carried out, which allows achieving high density and strength of materials. Special attention is also paid to studying the effect of mechanoactivation time and subsequent spark-plasma sintering on the microstructure and mechanical properties of tungsten carbide alloys. Understanding the relationship between mechanoactivation time and the properties of the resulting alloys is crucial for optimizing the production processes of tungsten alloys used in various industrial applications.

SOLVABILITY OF A BOUNDARY VALUE PROBLEM FOR FUNCTIONAL-DIFFERENTIAL EQUATIONS OF PANTOGRAPH TYPE

2025-06-18T05:34:27+00:00

The first equations of the pantograph type were considered in the works of M. Mahler in 1940, which laid the foundation for the use of functional-differential equations with argument compression in number theory. In 1971, J. Ockendon used such equations to model the movement of the current collector of an electric locomotive. In recent decades, pantograph-type equations have been widely used in engineering and construction: adjustable (pantograph) telephone holders, retractable (pantograph) microphone systems, etc.

This article studies a two-point boundary value problem for a system of functional-differential equations of the pantograph type. The parameterization method proposed by Professor D. Jumabayev is used to find a solution. The interval is divided into parts of equal length; the values of the desired function are determined by parameters at the initial point characteristic of each part, and substitutions of a specific form are introduced in the inner intervals.
As a result, the original boundary value problem is formally decomposed into two interrelated subproblems:

a special Cauchy problem for the functional-differential system of the pantograph type;
a system of linear algebraic equations with respect to the input parameters.

The special Cauchy problem for the functional-differential system of the pantograph type and the system of linear algebraic equations with respect to the input parameters obtained in this way form a closed system, and this closed system completely determines the solution of the original boundary value problem. The article presents a computational algorithm based on the above structure and discusses its effectiveness in the numerical analysis of pantograph-type functional-differential models.

ON THE SOLVABILITY OF CERTAIN BOUNDARY VALUE PROBLEMS FOR A NONLOCAL POLYHARMONIC EQUATION WITH BOUNDARY OPERATORS OF FRACTIONAL ORDER

2025-07-07T12:42:32+00:00

This paper investigates the solvability of certain boundary value problems for a nonlocal polyharmonic equation. The nonlocal polyharmonic operator is introduced through a new class of nonlocal polyharmonic operators using involution-type mappings. Boundary value problems with Dirichlet conditions and boundary operators of fractional order are considered. The solvability of a boundary value problem with Dirichlet conditions for the corresponding nonlocal polyharmonic equation is studied. First, the existence and uniqueness of the solution to Problem D are established, and the corresponding theorem is formulated. Based on this theorem, an explicit form of the Green's function and an integral representation of the solution to Problem D are obtained. The second problem under consideration involves boundary operators of fractional order, which are defined using modified Hadamard derivatives. The properties of mutual invertibility of the Hadamard-type integro-differential operators and are presented, and the smoothness of the functions and in Hölder classes is established. Based on these properties of the integro-differential operators, the existence and uniqueness of the solution to the corresponding problem are proved under the condition , and in the case , a necessary and sufficient condition for the existence of a solution is determined. As a result, theorems are proved that confirm the existence and uniqueness of solutions for the problems under consideration.
