3D aerodynamic analysis of awing with 2- way fluid-structure interaction. [Текст] / O. Sayakov // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №4. - P. 129-134

Кл.слова (ненормированные):
NACA 23012 airfoil -- Fluid-Structure Interaction -- ANSYS -- strongly coupling study -- deformation of the wing
Аннотация: the aircraft wings facing different weather conditions start to deform and oscillate with an unpredictable velocity and amplitude. Most of the previous studies were conducted assuming the wing as a rigid body.However, the wing analysis with Fluid-Structure Interaction(FSI)has significant effectson the results. This paper compares the strongly coupled 2-way FSI analysisof the flexible wing with a geometry of NACA 23012and a rigid body 2D winganalysis. Both studies were carried out at a Mach number of 0.075 and Reynolds number of 0.6×106for different angles of attack.Moreover, the analysis of the wing deformation at the start of the flight is also presented. Finally, it was shownthat FSI analysis gives closer results to the experimental measurements, proving the worthiness of the extra efforts of the two-way FSI analysis

Аннотация: At present, work in all areas is computerized and automated. All data is stored in a database. It is very comfortable and provides stability. For example, in the early 1980 - early 1990, all documents were filled in manually. It was a long process. When stored in the archives, there were layers of paper. And they could disappear and wear out. And the database data recorded by the computer is stored for a long time and does not take up much space, and you can store a very large amount of data.

Sentiment analysis of Kaspi product reviews. [Текст] / K. Yerassyl // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №5. - P. 68-73

Кл.слова (ненормированные):
sentiment analysis -- classification -- text analysis -- reviews -- data collection
Аннотация: Customer reviews are the key to the success functionality for the companies. A producer will gain the true result of his products from the customer feedback. What should the seller do to achieve good quality for his product? Just by looking at the stars and reading the usual text, the seller will not be able to improve their product well enough, because different people can understand the same text in different ways. That’s why, the seller can improve the wrong part of their product and make their product worse. Sentimental analysis can be applied here. He can make necessary changes to his product according to the feedback. However, it is common to see when most client may inadequately overestimate or underestimate the mark. To avoid the confusion, it is better to analyze the text. This paper focus on the sentiment feedback analysis and finding the relationship between reviews and ratings on the basis of data collected from ”Kaspi.kz” marketplace. These data streams are cleaned and analyzed and reviews is got through opinion mining. We used several algorithms to find the best one. The experiments have shown 92% accuracy in the sentimental analysis
