Creation of automated jobs for ''Loans and deposits in the banking system'' in the Delphi environment. [Текст] / G. T. Jussupbelova // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №5. - P. 61-67

Borland Delphi -- OLE technologies -- institutional structures -- deposit insurance system
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

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

machine learning methods -- modeling of machine learning method -- network equipment failure forecasts -- LAN
Аннотация: The article discusses three methods for predicting network equipment failures and the impact of the data array of input controllers. The purpose of the article is to reveal the relevance of the approach proposed by the authors to the use of large-amount of data in the chosen method of machine learning and to make a comparative analysis of the final values with the works of other world researchers. In the first section, the authors analyze the work of scientists from the Beijing University of Post and Telecommunications, noting the strengths and weaknesses of their method. In Section 2, the authors analyze the Holt-Winters method for developing algorithms for analyzing network traffic, which was applied by researchers from the Tomsk State University of Control Systems and Radio Electronics. In section 3, the authors applied the method of random trees in the modeling of machine learning methods of Rapid Miner Studio. The authors have carried out work with a large amount of data, and a comparative analysis of the results of modeling the method. The importance of using large amounts of information to train a model of network equipment failure forecasts is proved. In the final section, the authors highlight the need to improve forecasting models for its further implementation in the working environment. Also, the authors emphasize that the two articles considered by international researchers are a special case, as well as their chosen method for predicting failures in the LAN system.

Аннотация: The article presents experimental results obtained by studying the magnetoresistance of n-type silicon with an electron concentration of. nе=3,1-1013см-3 in the temperature range of 77.4-300K.There is a negative longitudinal magnetoresistance due to the redistribution of electrons between thevalleys. Experimental results are compared with existing theories and a good agreement is obtained bothquantitatively and qualitatively. At H=350 kE, the energy gap between the lowest Landau subzones is 7 MeV.These experimental results obtained in n-type silicon clearly demonstrate the reliability of the mechanismof negative magnetoresistance caused, indeed, by the pumping of current carriers between the valleys of theconduction band, shifting along the energy scale in a quantizing magnetic field at different speeds. The isenergetic surface of the bottom of the silicon conduction band consists of six ellipsoids located on the mainaxes of the cube, which causes anisotropy of the effective mass and relaxation time. The latter determines thefeatures of galvanomagnetic effects. Especially magnetoresistance is the most sensitive to the anisotropy ofthe is energetic surface. The influence of the latter on magnetoresistance is most clearly revealed in the regionof strong magnetic fields, where magnetoresistance is saturated.

Аннотация: The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

In order to adapt for mass cultivation, algae were first grown in greenhouse conditions. The algae were cultivated within 12 days. The produc-tivity in the tubular cultivator with stirring of Sp.platensis was 3.8 g / l, protein (73.0%), and Sp.laberinthiformis was 2.6 g / l of protein (63.1%). Similar studies were carried out in the open-air conditions that showed an increase in the amount of illumination causes a significant restructuring of the entire photosynthetic apparatus of algae. The accumulation of Sp.labyrinthiformis 2.7 g / l a.d.c., protein 62.21%, and Sp.platensis 4.08 g / l, protein 75.3%, were within 10 days. The content of protein and carotenes sharply increases in comparison with the greenhouse conditions. It was found that the addition of Sp.platensis suspension, as a protein-vitamin supplement for the bulls’ feedstuff, stimulates physiological processes that improves the biochemical parameters of their blood, the digestibility coefficient of nutrients by 8-9%, positive mineral balance, increases live weight gain (17.4%) and slaughter yield of the bulls (3.6%). So, the suspension of Sp.platensis is recommended for use as a protein-vitamin supplement in livestock farms that will allow having a significant economic effect in livestock farming, in average 20-25% profits per yearly.

Аннотация: The qualitative and quantitative compositions of the valuable biologically active substances, species and strains of microalgae are related the genus of CyanobacteriaSp.platensis and Sp.labgrinthifosmis that were isolated from local nature and grown in semi-production facilities were considered. In order to adapt for mass cultivation, algae were first grown in greenhouse conditions. The algae were cultivated within 12 days. The produc-tivity in the tubular cultivator with stirring of Sp.platensis was 3.8 g / l, protein (73.0%), and Sp.laberinthiformis was 2.6 g / l of protein (63.1%).
