In this case, information about the object with the help of the decision maker is described in the form of a membership function that takes its values on a set of non-negative numbers. Three groups of preference relation models are considered, such as: clear preference relations, fuzzy preference relations, linguistic preference relations.</p> Kamolov E. R.

As a result, the level of students' mathematical knowledge increases, and they begin to study all topics of mathematics more deeply</p> Nafasov Ganisher Abdurashidovich, Eshkuvatov Kozim Copyright (c) 2024 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6519 Sun, 08 Dec 2024 00:00:00 +0000 Teaching The Basics Of The Internet Of Things In A Distance Format https://geniusjournals.org/index.php/ejpcm/article/view/6539 <p>The article considers the experience of teaching the basics of the Internet of things in a distance format. The authors describe the chosen approach, the tools used, and the learning outcomes. Simulators such as Wokwi have been used to create virtual models of IoT devices and systems. The process of creating and debugging projects, as well as setting up automation scripts using the Google Colab cloud platform, is described. In conclusion, the authors summarize the results of the experiment and give recommendations for organizing IoT distance learning.</p> Ruzimurodov Ikhtiyor Nishanovich, Nishonov Sardor Ixtiyor ogli Copyright (c) 2024 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6539 Wed, 18 Dec 2024 00:00:00 +0000 Specific Vibration Of A FluidConducting Toroidal Shell https://geniusjournals.org/index.php/ejpcm/article/view/6550 <p>In this work, the problem of specific vibration of the fluid-conducting toroidal shell is solved. The object of the research is to evaluate the ideal fluid and the composite toroidal shell with rheagogic properties, their characteristic (or special) vibrations and dynamic characteristics. Research methods. The integral differential equations with eigenvalues are reduced to the system of ordinary differential equations. To solve these equations, freezing method, separation of variables method, Muller's method, and Godunov's orthogonal projection methods were used. The reliability of the obtained results is based on the correct formulation of the spectral limit problem, the rigor of the derived mathematical expressions, the use of based solution methods and the evaluation of the accuracy of the solutions, as well as comparisons with the solutions of other mathematical</p> Toyirov Gayrat Fozilovich , Jurayev Shukhrat Isroilovich Copyright (c) 2024 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6550 Mon, 09 Dec 2024 00:00:00 +0000 Formation Of Methodological Components For Solving NonStandard Problems In Mathematics https://geniusjournals.org/index.php/ejpcm/article/view/6551 <p>Below in this article, an opinion is expressed about the necessary, targeted introduction of methodological innovations aimed at solving non-standard problems on the topic of mathematics “Pythagorean Theorem” among students of general secondary education, special and presidential schools.</p> Ubaydulloyev Farrukh Barakayevich Copyright (c) 2024 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6551 Mon, 16 Dec 2024 00:00:00 +0000 Limit calculation technology using linear substitutions https://geniusjournals.org/index.php/ejpcm/article/view/6596 <p>The article discusses the issues of simplifying the calculation of some non-standard sequences and limits of functions using linear substitutions, lemmas, and theorems.</p> Abdusalom Khakimov Copyright (c) 2025 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6596 Sun, 29 Dec 2024 00:00:00 +0000 Features Of Optical And MagnetoOptical Spectra Of Rare-Earth Ions Ho3+ And Tb3+ In Garnet Crystals https://geniusjournals.org/index.php/ejpcm/article/view/6560 <p>The article is devoted to the analysis of the results of experimental and theoretical studies of the relationship between magneto-optical and optical-magnetic effects with the features of the Stark structure of the energy spectra of non-Kramers RE ions in garnet crystals.</p> U.R.

In many cases, ordinal statistics are used as estimates in problems of estimating unknown parameters. In order to check the properties of these estimates and to assess their error, it is necessary to know the distributions of ordinal statistics. Therefore, the study of ordinal statistics and their distributions is of great importance. This qualification thesis is devoted to these issues.</p> Gulnoz Sayfulloyeva, Shokirova Durdona, Ibragimova Dildora, Bozorboyeva Dildora Copyright (c) 2025 https://creativecommons.org/licenses/by-nc/4.0 https://geniusjournals.org/index.php/ejpcm/article/view/6598 Sun, 29 Dec 2024 00:00:00 +0000
