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

The article presents methods and algorithms for analyzing and evaluating the effectiveness of business processes of enterprises using a system of balanced indicators. Due to the increased requirements for the efficiency of the functioning of organizations, the process approach based on the development of a process management system is becoming more popular. The activity of organizations is considered as a set of business processes with reference to structural divisions. The effectiveness of informatization and automation of algorithms for the work of enterprise entities primarily depends on the degree of formalization of business processes of organizations and readiness to implement management systems that meet the modern requirements of the digital economy.

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: According to UN estimates, the shortage of safe drinking water can become one of the most acute and pressing problems. The specificity of this problem for Russia is not a shortage of water resources, but their pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring its condition and properties. During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region, studied the dependence of the quality characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of drinking water were drawn. During the experiment, the authors found that in terms of organoleptic indicators, drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt content is mainly due to the presence of hardness salts. Having made the necessary analyses, the authors found that the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations.

Аннотация: Универсальные стрессовые белки (Universal Stress Proteins, USP) являются потенциальными участниками процессов, контролирующих морфогенез растений, в которых важная роль отводится фитогормонам. В данном исследовании был выполнен поиск генов USP Arabidopsis thaliana, изменяющих свою экспрессию в ответ на действие фитогормонов. Выявлены 15 генов USP, экспрессия которых дифференциально регулируется двумя и более фитогормонами. Причем, накопление транскриптов у большинства из исследованных генов наблюдали при действии гормонов, участвующих в формировании устойчивости растений к стрессу – абсцизовой кислоты, этилена и метилжасмоната. В то же время ауксины и гиббереллины – гормоны, регулирующие рост растений, – подавляли экспрессию изученных генов USP. Полученные результаты выявили потенциальные гены USP, чья функциональная активность напрямую или опосредовано может быть связана с фитогормон-зависимыми процессами, обеспечивающими жизнедеятельность растений в нормальных и стрессовых условиях.

Аннотация: In the present paper, the issues of studying the influence of complex activation of grouting fluid on the structure and properties of the hardened cement paste and concrete are considered. The problem is relevant for manufacturing of building materials. In the paper, there was used the method of applying in the concrete mix composition of the elementary chemical substances undergone special physical treatment by means of mechanomagnetic activation. For more profound study of the structure formation processes in the hardened cement paste, the method of differential thermo gravimetric analysis has been used. As the research results have shown, the concrete samples on the activated electrolyte solutions are characterized by improved strength. In addition, on the base of differential thermo gravimetric analysis, it was proven that in the studied samples of the hardened cement paste on the electrolyte solutions activated by the method of mechanomagnetic treatment, the less calcium hydroxide and the more hydrated calcium silicate with amorphous and fine crystalline is formed. The obtained results for cement composites could be applied when manufacturing effective binder for concretes and mortars in the production of building materials and structures.

The obtained results for cement composites could be applied when manufacturing effective binder for concretes and mortars in the production of building materials and structures.
