Mathematical Modeling and Computational Experiment of the Process the Atmospheric Transport of Salt-Dust Aerosols from the Aral Sea Basin

    2022-03-20 DOI:

Daler Sharipov, Dilshot Akhmedov

Atmospheric transport of salt-dust aerosols is a sophisticated effect mainly depending on the meteorological situation. Since the dried bottom of the Aral Sea is considered as emissions source, precisely the wind removal of aerosol particles is implied here. It should be noted that the wind erosion of the ground cover can be considered as a special case of the hydrodynamics of multiphase flows, which is of particular scientific interest. In this regard, vertical wind profile, which depends on the roughness of the ground cover and the stability of the atmosphere, become to one of essential aspects for outdoor airflow simulations. Thus, the aim of this work is to study the influence of the vertical wind profile on the atmospheric transport of salt-dust aerosols. The results of computational experiments on the airflow characteristics at various heights, values of the ground-level wind speed and the roughness coefficient are presented in the paper. As well as the results of numerical calculations demonstrating the influence of the horizontal and vertical components of the wind speed on the distribution of suspended aerosol particles within the considered area.

Artikova M, Talipova O

This article gave an example of creating a program for translating text into audio. In the conditions of the modern language situation, the national school faces an important task - the formation of the ability to solve various communicative tasks in certain areas and situations of communication by means of language. The ultimate goal of teaching languages at school is the practical mastery of them. Achieving this goal is directly dependent on the use of effective methods, techniques and teaching aids. Now in the public domain there are many speech synthesizers that allow you to convert text into voice. They are developed by a variety of companies and independent users, constantly improving reading algorithms, making the tool even more accurate during its work. For successful playback and additional settings, you will need special software, the functionality of which allows you to implement the task. The program in this article is very similar to one of the google translator functionality. Unfortunately, due to the limited base of google languages, the translator cannot translate some words of the Uzbek language into audio. This article describes the technology and process for creating this software. The software was created in the form of a web application.

    2022-03-25 DOI:

Alijon Guliev

This article proposes the use of a non-invasive method based on measuring the electrical resistance of bioactive points located in the meridians of the human body in diagnosing diabetes. Using analysis of variance, it was found that the existing meridians in the human body are not equally important for diagnosing diabetes, shows that each meridian is actually related to some internal organs in the body. An analysis of variance was carried out, and the influence of one or more factors affecting a random variable in complex situations was assessed by carefully studying various sources that cause differences in the values of a random variable over the same time interval. Practical use has been made, and as a result, it has been found out that there are many cases when only one factor affects the final result, and this factor takes a finite number of values. Numerous computational experiments were carried out on the basis of software products, various situations were tested, and the results were analyzed using a single-factor analysis of variance. It is noted that if a person has a disease before his symptoms are detected, all pathological signs first reach the meridians along the nerve fibers, and then reach the points already existing in these meridians. As a result, the disease leads to a meridional imbalance, and there are sharp changes in the sum of biophysical indicators at points located in the meridians.

Raimkulov Ural, Sayfiyev Eldor, Juraboev Fozil

This article looks at the capabilities of the most common arduino device today, where to use it, and what your platform is capable of. It is explained what knowledge and skills the user should have before using the platform. Arduino platform and the process of working with the arduino microcontroller, as well as ideas on how to create projects using arduino. Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. The Arduino platform has become quite popular with people just starting out with electronics, and for good reason. Unlike most previous programmable circuit boards, the Arduino does not need a separate piece of hardware (called a programmer) in order to load new code onto the board -- you can simply use a USB cable. Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program.

    2022-06-11 DOI:

D.A.Davronbekov, A.F.Khayrullaev

Electricity theft is the biggest problem today, which causes huge losses to electrical panels. In addition, to hide these losses, the price will eventually increase. If we can prevent these thefts, we will be able to save a lot of energy. By tracking the electricity used, you will find out where the best opportunity to save energy is. More than one-third of the electricity generated is lost due to electricity theft, power loss and inefficiency of the distribution system. Prohibited or illegal use of electricity not only has an economic impact, but also hinders the design and modeling stages of the power system. This paper proposes a real-time remote transmission line condition monitoring system to ensure the prospects of safe operation of overhead power lines. The proposed system is designed for low-voltage transmission lines (0.4 - 6 kV) and provides information about the condition of the line between the distribution transformer and the consumer meter. Many households indulge in different forms of electricity theft and illegal tampering of electric metering devices. These lead to distribution system faults and overload as well as loss of revenue by the distribution companies. In particular, the application of sensor network in the remote monitoring system, the use of the modern Arduino Mega microcontroller offers the possibility of more accurate and reliable monitoring of the characteristics of overhead power lines.

The main characteristics of optical fiber amplifiers for optical transmission systems

    2022-09-20 DOI:

Siddikov Isomiddin Khakimovich, Fayzullayeva Barno Bakxadirovna

The article is dedicated to an overview of the various options for optical fiber amplifiers, the principles of their operation, advantages and disadvantages. The article presents drawings of various characteristics of amplifiers and a diagram of a structure with a combined DFB - laser and optical amplifier, and a functional diagram of a FOA - a fiber optic amplifier. When transmitting optical signals over fiber communication lines over long distances, due to scattering and absorption, which attenuate the information signal, it is necessary to use repeater amplifiers in series. We know that there are two types of repeaters – optic-electronic, based on the conversion of “light - electronic signal - light", and fully optical, which have recently become widespread. The main limiting factors in fiber optic transmission systems are attenuation, dispersion, and non-linear optical effects. This chapter deals with devices - optical amplifiers, which compensate for optical power losses that occur in optical fibers, connectors, passive splitters, etc.

Rakhimov B.N., Babajanova A.T., Berdiyev A.A.

Since the parameters of the atmosphere are dynamic, real-time monitoring of meteorological parameters is a difficult task. The measurement time t of the sensors used to measure atmospheric parameters is different, and the measurement period of the sensors used for the system does not end at the same time. This problem reduces the accuracy of data in systems that perform special tasks. In this article, in order to improve the accuracy, a method and algorithms for obtaining θ data at the end of the sensor measurement time for one period and processing the sensor data were developed. The problem of integrating measured data is investigated and a method of temporal data integration is proposed. For synchronous operation of meteorological data, time cycles for measuring meteorological parameters are provided.

Digital Processing of Visual-Sensory Information Using Multichannel EEG

    2022-12-20 DOI:

Kamola Abdurashidova

A relatively new but growing field of EEG application is braincomputer interfaces (BCIs). BCI is a technology that provides communication between the brain and the computer. BCI is a computer system that receives brain signals, analyzes them, and converts them into commands that are sent to an output device to perform the desired action. The main goal of BCI research is to create a new communication path that allows you to directly transmit messages from the brain by analyzing the mental activity of the brain in people with severe neuromuscular diseases, as well as controlling various household electrical appliances using remote control. To measure the EEG signal, a headgear with electrodes (EEG cap) is put on the user's head. To control a machine (computer), the user imagines a specific task, such as moving limbs or forming words. These mental tasks act on patterns of EEG signals and determine characteristic states using special recognition algorithms based on fast Fourier transform (FFT) and neural networks. The resulting templates are broken down into classes and executed as required commands. For example, to control a computer application (such as cursor movement) or a machine (such as a wheelchair), it detects and classifies these patterns into different tasks. This article is devoted to the development of a software tool that analyzes and classifies electrical multichannel EEG signals of the brain in the process of processing visual sensory information based on the above methods and tools.

Kim E.V., Muchtapova G,X., Kuznetsova V. B.

The article presents the results of a study of the digitalization of informative features of erythrocyte images during their adhesion for the purposes of medical microscopic analysis. The contour spectrum of erythrocyte images was chosen as an informative feature. In this paper, we propose an approach to the analysis of the shape of erythrocyte images and, in particular, to solving the problem of analysis when they stick together. The aim of the work is to study the informative features of images of erythrocytes during their adhesion and to develop a methodology for analyzing these images during their adhesion for the purposes of medical microscopic analysis.Thus, the problem of creating automated and relatively inexpensive information complexes for the analysis of blood cells remains relevant.Thus, in the course of the work, the informative signs of images of adherent erythrocytes were studied. The contour spectrum of erythrocyte images was chosen as an informative feature. The features of the spectra during erythrocyte agglutination were obtained. An analysis of the contour spectra of images of adherent erythrocytes makes it possible to answer the question about the number of adherent cells and their area of mutual overlap. These features make it possible to identify a certain dependence, which in turn indicates the possibility of developing an automated system for analyzing blood cells.

Shohruh Safarov, Zarif Qodirov

In this article, a mathematical model based on the Hamilton-Ostrogradsky variational principle is presented. Using the Kirkhgoff-Lyav hypothesis, transform the mathematical model in 3D form into his 2D model. The tensor view is used to determine variational representations of potential and kinetic energy, as well as changes in work done by external forces, Cauchy relations, Hooke's law, Lorentz forces, and Maxwell's electromagnetic forces. In this case, the influence of the electromagnetic field on the deformation stress state of the magnetoelastic plate is taken into account. The result was a mathematical model in the form of a system of higher-order differential equations with special derivatives with initial and boundary conditions on the displacements. To solve this problem, we developed computational algorithms, created practical software tools, performed computational experiments, and analyzed the results obtained.

H.N. Zaynidinov, A.M. Rasulov, M.A. Kuchkarov, X.X. Mamirov, T.B. Boltaniyozov

In the present paper, an algorithm to compute an accurate TOF is proposed. The form of the electric signal received by the transducer is obtained from an acoustically-forced underdamped oscillator model, and the analytical solution of the model is proposed as a reference wave. In order to validate the effectiveness of this procedure, an ultrasonic flowmeter system is designed and tested in a flowmeter calibration test rig. It is demonstrated that the use of the presented scheme overcome the average method limitations, and turns out to be a convenient solution in a wide range of conditions. Robust measurements of near-zero flow values are acquired, which allow the achievement of a high dynamic range. The error curve of the proposed system have been obtained, revealing that the absolute value of the relative errors are lower than 2% within all the spectrum of flow rates considered (from 0.2 to 150 m3/h). Results demonstrate that the algorithm provides high-precision measurements within a wide dynamic range. The algorithm is portable and versatile: it can be adapted to different types of transducers without the need of additional measurements, allowing to adjust parameters on-the-fly for an optimal performance of the ultrasonic flowmeter system.

In recent years, the interest in image super-resolution is increased sharply developing the field of research in Image processing. Image super-resolution is a technology that increases the resolution of an image, typically by upscaling it to a higher resolution than the original. This can be achieved using machine learning algorithms such as convolutional neural networks (CNNs) that have been trained on large datasets of high-resolution images. The goal of image super-resolution is to enhance the quality of low-resolution images, making them more precise and detailed. In this paper, image super-resolution concepts, types, and applications were described, also was given brief information about super-resolution frameworks by authors. Super-resolution frameworks are computational approaches or algorithms designed to enhance the resolution and quality of images or videos. These frameworks leverage various techniques, including traditional image processing methods and advanced deep learning techniques, to generate high-resolution versions of low-resolution inputs. They aim to reconstruct fine details, improve image clarity, and enhance overall visual quality. Super-resolution frameworks can be based on convolutional neural networks (CNNs). These frameworks play a crucial role in various applications such as digital photography, imaging, and video processing, where higher resolution and better image quality are desired.

STUDY OF THE FEATURES OF FIBER-OPTIC AMPLIFIERS USED ON EXTENDED COMMUNICATION LINES

    2023-03-18 DOI: 10.61663/tuit23.1.5

D.A. Davronbekov, N.I.Juraeva

Optical amplifiers used in extended fiber-optic communication lines are considered. Optical amplifiers are used on extended fiber-optic communication lines to compensate for the losses created by the fiber transmission medium. These devices provide internal amplification of the optical signal without converting it to electrical form. In this paper, the main properties of doped-fiber amplifiers and Romanov amplifiers, as well as hybrid amplifiers, are considered. Dopant-fiber amplifiers are the most widely used and are a key element in all-optical network technology, as they allow signal amplification over a wide spectral range. Higher signal quality requirements do not allow the use of high-performance modulation formats in communication lines with traditional erbium amplifiers. In addition, in existing communication lines, over time, due to natural causes or due to repair work, losses may increase and operability will be disrupted. The use of hybrid amplifiers in long-range communication systems with dense spectral multiplexing leads to a decrease in the noise level in the receiver, an increase in signal quality and an increase in throughput. Currently, a hybrid amplifier, as well as a broadband Raman amplifier, is used in fiber-optic communication lines. The presence of two types of amplifiers allows you to create more economical solutions.

Model for transmitting URLLC packets in 5G networks

    2024-04-10 DOI:

Amirsaidov Ulugbek

5G New Radio (NR) will support a new Ultra Reliable Low Latency Communications (URLLC) service designed to support small packets transmission with very strict latency and reliability requirements. Grant-free (GF) scheduling has been proposed for URLLC instead of the traditional high-latency grant-based (GB) scheduling adopted in 4G Long Term Evolution (LTE) networks. Although GF scheduling on shared resources provides lower latency, the ability to achieve the URLLC reliability requirement may be defaced due to the increased probability of collisions. In this paper, the optimal configuration of the modulation-code scheme and the number of retransmissions of Uplink Grant-Free URLLC packets are determined. Analytical expressions have been developed for calculating the service characteristics of URLLC traffic depending on the quality of the communication channel, modulation code scheme (MCS) parameters and the number of resource blocks required to transmit a packet after encoding it.

    2024-06-24 DOI:

Ravshanov N., Tashtemirova N.N., Ubaidullaev M.Sh.

The work solves the conjugate stationary and non-stationary problems of the process of transfer and diffusion of harmful substances in the atmosphere, taking into account the absorption coefficient, which depends on weather-climatic factors and external disturbances, and the coefficient of adhesion of aerosol particles by vegetation, where dual functionals were obtained for them for optimal resolution of industrial facilities in the region and obtained analytical solutions for the above tasks. Numerical calculations were carried out on a computer and it was found that the particle capture parameter by vegetation is significant, which depends on the type and size of vegetation and takes on different values, varies depending on the time of year, and with an increase in the particle capture parameter, the concentration of harmful substances in the atmosphere decreases proportionally. Computational experiments have established that the concentration of harmful substances in the ground layer of the atmosphere decreases over time with an increase in the coefficient of absorption and capture of particles by vegetation, and the process of molecular diffusion of harmful substances in the atmosphere depends on the diffusion coefficient and with an increase in the diffusion coefficient, the area of distribution of harmful substances in the ground layer of the atmosphere increases .

FEATURE SELECTION IN MULTI-OUTPUT CLASSIFICATION USING RECURSIVE FEATURE ELIMINATION: A CASE STUDY ON MEDICAL DATA

    2024-09-18 DOI:

Sharipov D.K., Saidov A.D.

This study investigates the use of Recursive Feature Elimination (RFE) for feature selection in multi-output classification, particularly with a medical dataset. The classification task requires predicting several related binary outcomes simultaneously, making feature selection vital for reducing dimensionality and enhancing model performance. RFE is applied to each target variable, and common features across all targets are identified to refine the feature set while preserving prediction accuracy. A RandomForestClassifier, paired with a MultiOutputClassifier, is used to assess the predictive power of the selected features. The results indicate that RFE improves classification efficiency by removing redundant and irrelevant features, resulting in a model that is both more interpretable and computationally efficient. This method shows potential for optimizing multi-output medical classification tasks, providing advantages in healthcare data analysis.

The article discusses a method for preventing SQL injections and cross-site scripting using the Knuth-Morris-Pratt string matching algorithm. SQL injection and cross-site scripting remain a major threat to data-driven web applications. There are more and more cases where hackers gain unlimited access to the internal database of web applications in order to steal, edit and destroy confidential data. Therefore, measures must be taken to curb the growing threats of SQL injection and XSS attacks. This study presents a technique to detect and prevent these threats using the Knuth-Morris-Pratt string matching algorithm. The algorithm was used to match the user's input string with a stored injection string pattern to detect any malicious code. The implementation was carried out using the PHP scripting language and the Apache XAMPP server. The security level of the method was measured using various test cases of SQL injection, cross-site scripting (XSS), and code injection attacks. The results obtained showed that the proposed technique is able to successfully detect and prevent attacks, register an attack record in the database, block the system by its mac address, and also generate a warning message. Thus, the proposed technique turned out to be more effective in detecting and preventing SQL injections and XSS attacks.

Shohruh Safarov, Mashrab Matlubov

In the article, based on the Hamilton variational principle, a mathematical model of the process of geometric nonlinear deformation of thin magnetoelastic plates with a complex structural shape was developed and calculations were performed. In this case, the three-dimensional mathematical model was transferred to a two-dimensional view using the Kirchhoff-Liav hypothesis. Cauchy's relationship, Hooke's law, Lawrence's force, and Maxwell's electromagnetic tensor were used to determine kinetic and potential energy and work done by external forces. The effects of the electromagnetic field on the deformation stress state of the magnetoelastic plate were observed. As a result, a mathematical model in the form of a system of partial differential equations with initial and boundary conditions was created. To solve the equation, a calculation algorithm was developed using the R-function, Bubnov-Galerkin, Newmark, Gaussian, Gaussian squares, and Iteration numerical methods. Calculations were carried out in various mechanical states of the magnetoelastic plate, its boundaries were fixed, one side was hinged and the other side was free, and numerous results were obtained.

This article examines cybersecurity issues that affect the efficient and fully functional operation of information systems which have rapidly integrated into human activities today. It analyzes approaches to identifying and eliminating cybersecurity threats not only during the creation of information systems but also at the stage of their architecture formation. The application of STRIDE, CWE, and OWASP methodologies and their shortcomings are highlighted. It should be noted that a comprehensive analysis and description of the information system`s services in threat modeling leads to the maximum formalization of potential threats. It is known that the software development lifecycle is recognized as a standard for all programmers. However, cybersecurity experts acknowledge that even in this scheme, there are insufficient stages that account for all cybersecurity threats. To address this, it is proposed to identify cybersecurity threats at the initial stages and define measures to eliminate them by introducing additional processes into the lifecycle of SDLC information system development. In this regard, it is important to develop a metamodel of information system elements and formalize the forms of activity.

The Importance of Artificial Intelligence in Information Systems

Nazarova Gulchexra, Boboqulov Abbos

Evolution of AI definition; AI has a history much longer than is commonly understood, in fields from science and philosophy ranging all the way back to ancient Greece (Dennehy, 2020), but its modern iteration owes much to Alan Turing (Turing, 1950) and conference in Dartmouth College in 1956 (McCorduck, 2004), where the term Artificial Intelligence was officially coined and defined by John McCarthy at the time as the science and engineering of making intelligent machines. Russel and Norvig (2020) referred to it as the the birth of artificial intelligence. One of the initial paradigms of AI was that it revolved around high-level cognition. Not the ability to recognise concepts, perceive objects, or execute complex motor skills shared by most animals, but the potential to engage in multi-step reasoning, to understand the meaning of natural language, to design innovative artefacts, to generate novel plans that achieve goals, and even to reason about their own reasoning (Langley, 2011). This general human like intelligence was referred to as strong AI (Kurzweil, 2005). For strong AI, the primary approach has centred on symbolic reasoning, that computers are not simply numeric calculators but rather general symbol manipulators. As noted by Newell and Simon (1976) in their physical symbol system hypothesis, intelligent behaviour appears to require the ability to interpret and manipulate symbolic structures. While this approach showed promise initially (Newell & Simon, 1963), many branches of AI have retreated from this approach due its difficulty and the lack of progress coming in to the 21st century. It remains yet uncertain on when and if strong AI will be made a reality.

This paper first describes the methods for creating and implementing L-systems, conducting research on the various graphs generated by them. Since the number of graphs generated based on the basic principles is limited, this paper aims to gradually diversify the L-system rules through various operations such as context switching and inheritance modification, producing a wide range of new, unexpected plant-like and abstract forms. The resulting artistic figures are then processed and applied to the design of textile patterns using the image processing software Photoshop. This research not only improves the algorithm and graphics of L-systems, but also provides a new perspective on the production of textile patterns.

Kuchkarov Muslimjon

The problem of misallocation of cache lines in processors is studied based on the specific features of memory organization in multi-core and multi-processor systems of distributed systems. Incorrect allocation of cache lines leads to sequential execution of tasks that should be executed in parallel on several cores. It is difficult to determine the problem, and its presence can cause a sharp decrease in the performance of the entire system. In many seismic studies, scientists` efforts are aimed at finding reliable signs of seismic hazard. Abrupt changes in one or another parameter are called abrupt effects, emissions or anomalies, through which the principle of prediction can be implemented - this means predicting the place, strength and time of a future seismic event. The use of distributed systems in the implementation of predictions with the help of machine learning, digital processing of large volumes of digital signals, ensures fast and high-quality determination of results. To increase the speed, it is necessary to develop parallel algorithms.

The purpose of the study is to develop mathematical methods and algorithms for taking into account the uncertainties of the initial parameters when solving the transport problem in the exchange of information between corporate information systems. The research methods are based on the use of linear algebra, mathematical statistics and linear programming. Numerical modeling methods were used in the work to verify the performance of the proposed solutions. The mathematical expectation matrix and the covariance matrix are considered as such parameters. The covariance matrix characterizes the distribution of the initial parameters of the problem, which ultimately leads to a difference in the cost of transporting goods from the planned values. The presence of random parameters in the considered formulation of the problem is considered as a risk. The article presents a mathematical formulation of the problem, in which the optimization criterion is risk, and the total cost of transportation is taken into account as an additional constraint in the problem statement. For any selected value of the total cost, it is possible to estimate the probability that the random variable will fall into a certain interval. The article considers an example of solving the transport problem in the proposed formulation, taking into account the uncertainty of the initial values.

Polatov Askhad, Sapayev Shikhnazar, Matyakubov Marks

The distribution of the temperature field of elements of three-dimensional structures is examined in the article and the influence of non-homogeneities on the temperature field in three-dimensional axisymmetric structures is studied. Based on the variational formulation of the problem, a finite element model for solving axisymmetric problems of heat distribution in three-dimensional bodies was built based on the finite element method; a computational algorithm of the solution and the software were implemented. Shape functions corresponding to linear triangular elements are used in the finite element solution to the problem. They ensure its continuity at the boundary with neighboring elements since this distribution is linear along any side of the triangle and with the same change in value at the nodes, the same changes will occur along the entire inner boundary. A discrete finite element mesh model is a set of parameters that consist of the total number of finite elements and mesh nodes, arrays of their node coordinates, and node numbers of finite elements. To verify the reliability of the results obtained, a computational experiment was conducted, related to the study of the effect of the increase in the number of finite elements on the convergence of solutions. Analysis of the experimental results confirms the numerical convergence of temperature values as the finite element mesh is refined. At the initial stage of the study, the influence of temperature distribution for homogeneous structural elements was studied.

Halimov Shahzod

- This study investigates the gas motion through the froth of a prototype bi-dimensional flotation cell. Using advanced video and image analysis techniques, surface velocity data obtained with a Visiofroth system were validated by comparing them with manual tracking results of bubble motion on the froth surface. Images for manual tracking were captured using a high-speed video camera. Additionally, discharge velocity profiles were analyzed as a function of froth height over the launder lip under different froth Crowder angles and superficial air rates. An increasing froth discharge velocity from the lip level to the top of the froth was observed. Air recovery was estimated using the velocity profile and compared with values derived from surface velocity estimation. Results indicated differences from 24% to 47% in air recovery when froth flow area at the lip was considered. However, both approaches displayed similar trends under varying JG and froth Crowder angles. Using top-of-froth velocity alongside the froth flow area at the Visiofroth location resulted in air recovery values closer to those obtained from the discharge velocity profile at the lip.

Charos Khidirova, Alevtina Muradova

This paper presents a comprehensive study of defuzzification methods designed specifically for intuitionistic fuzzy sets (IFS), which extend traditional fuzzy sets by incorporating an additional dimension of uncertainty – hesitation. The research analyzes and compares three main classes of defuzzification techniques: centroid-based, score function-based, and hesitation-driven methods. Each approach is evaluated in terms of its ability to transform fuzzy data, described by membership, non-membership, and hesitation degrees, into meaningful crisp outputs that support more accurate decision-making. A significant contribution of this study is the application of the centroid-based defuzzification method in the medical domain, specifically for cardiovascular disease prediction. The paper outlines a framework where patient data is modeled using IFS and converted into a single risk score, enhancing clinical decision-making by quantifying uncertainty in diagnostic parameters. The results demonstrate that incorporating hesitation into defuzzification processes can yield more nuanced, reliable outcomes compared to traditional methods. The findings underscore the importance of selecting appropriate defuzzification strategies depending on the decision context and highlight the potential for applying IFS-based models in other complex and uncertain environments. The paper concludes with suggestions for future research, including hybrid techniques and broader applications in decision-support systems.

The article explores the potential of virtual reality (VR) and augmented reality (AR) technologies in the context of developing literary tourism in Uzbekistan. It presents a project aimed at creating a digital resource that comprehensively reflects the country's literary heritage through the development of a multilingual electronic platform and a mobile application based on VR and AR technologies. The study examines both conceptual and practical aspects of the digitalization of literary heritage, focusing on the creation of the "Literary Guide" electronic platform. The paper outlines technological solutions, including the implementation of virtual tours and the integration of marker-based and spatial AR technologies, and identifies key literary landmarks—specifically, the house-museums of prominent writers in Tashkent and Samarkand—covered by the project. The importance of innovative digital tools is emphasized for the promotion of cultural assets, enhancement of tourist experiences, and stimulation of post-pandemic development in the tourism sector. The results presented may serve as a foundation for further research and the adoption of similar initiatives in the field of cultural tourism.
