Кл.слова (ненормированные):
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 overall acceptability decreases when adding the non-roasted amaranth flour in a product. The main weakness of this study was the paucity of size of our panel (10 people). With a small sample size, caution must be applied, as the findings might not be transferable to show objective data.

Physicochemical and antioxidant properties of humic acids of low-mineralized peloids of the Tuzkol deposit. [Текст] / Zh. К. Кairbekov, I. M. Jeldybayeva, D. Z. Аbilmazhinova, S. M. Suimbayeva // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №3. - P. 48-53

Low-mineralized sludge sulphide mud (peloids) -- humic -- fulvic -- hymatomelanic -- humic acids -- antioxidant activity
Аннотация: As a result of studies it was found that the peloids of the deposit of Tuzkol Lake (Republic of Kazakhstan) are high quality medium-sulfide, weakly alkaline sludge muds. It was found that peloid-derived humic acid contains 49.63 % oxygen, 22.37% carbon, 9.65 % silicon and 6.26% calcium; it also contains Na, Mg, Al, Fe and an insignificant amount of S, Cl, K, F. Electron microscopy and IR spectroscopy analysis of the molecular structure of humic substances of peloids indicated that their macromolecule consists of framework olefinic and aromatic fragments with a substantial proportion of unoxidized aliphatic groups, as well as aromatic structures containing carboxyl groups. The findings of amperometric detection of the antioxidant properties of humic acids suggest that they have antioxidant activity, which will make it possible to use them as a biologically active substance for medicines.

bentonite -- montmorillonite -- sorption -- desorption -- degree of sorption -- Mn2 +and V4 +cations
Аннотация: the process of sorption of Mn2 +and V4 +cations by bentonite of the Tagan deposit studied depending on various factors (T, oC; τ, min; S: L ratio; CMnand CV, mg/l). It was found that bentonite exhibits sorption properties with respect to the studied cations in a wide range of pH values (from 1 to 10). The highest degree of their sorption is achieved at the consumption of bentonite 1.5 g per 100 mass. p.of metal-containing solution. The influence of the nature of the cation on the sorption capacity of Tagan bentonite was established. The most intense increase in the degree of sorption of manganese (II) occurs in 15 min with an increase in temperature to 35оС.The highest degree of sorption of V4 +cations is achieved in 60 min at 25°C in weakly concentrated vanadium-containing solutions (50 mg/l V4 +). Bentonite from the Tagandeposit exhibits a lower sorption capacity with respect to V4 +cations as compared to Mn2 +cations, which is due to the nature of the cation.
