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 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.

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%). 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 main goal of the study was to develop and test an effective technology for cattle genotyping by the CSN3 gene based on real-time PCR with hybridization-fluorescence detection. There was developed a method for real-time PCR for cattle genotyping by A and B alleles of the CSN3 gene in the format of hybridization-fluorescence detection, involving the use of two 5/-fluorescence-labeled forward allele-specific primers, one reverse common primer, and one anti-primer labeled with a fluorescence quencher at the 3/-end of the oligonucleotide. As a result of practical studies aimed at testing the developed method, we obtained the technical result provided by the proposed technology, expressed in the effective identification of the desired genotypes due to correct interpretation of these curves of increasing fluorescence intensity, the results reliability of which was also confirmed by the well-known PCR-RFLP analysis technique for Bos taurus genotyping for similar allelic variants of the kappa-casein gene.

Аннотация: В статье представлены анализ и результаты научных исследований техногенных шлаковых отходов свинцового производства. После закрытия и ликвидации завода, оставшиеся отходы в виде шлаков являются источником экологического загрязнения почвы, грунтовых вод и воздуха. Шлаки свинцового производства содержат большое количество токсичных соединений, таких как свинец, цинк, осмий, кадмий, которые являются опасными источниками экологического загрязнения. Утилизация техногенных шлаковых отходов имеет большое значение для снижения отрицательного влияния на безопасность жизнедеятельности и улучшения экологической обстановки региона. В то же время шлаки являются ценным сырьем, содержащим соединения цветных и редкоземельных металлов. В статье показаны результаты лабораторных исследований шлаков по определению качественного и количественного состава ценных компонентов в отходах свинцового производства и возможности дальнейшей их переработки и утилизации. Были проведены исследования материала тяжелой фракции шлака на электронно-зондовом микроанализаторе марки JEOL IXA–8230 Electron Probe microanalyzer. Рентгенодифрактометрический анализ средней пробы шлака выполнен на дифрактометре ДРОН-4 с Cu –излучением, графитовый монохроматор. Из проб были выделены тяжелые фракции и изготовлены полированные искусственные аншлифы (брикеты). Аншлифы изучались под микроскопом марки LEICA DM 2500P и в иммерсионных жидкостях. По результатам исследований выявлено, что в свинцовых шлаках содержится достаточно высокое количество соединений цветных металлов: оксида свинца до 0,7 % и оксида цинка до 8,5 % от весового количества шлака, что позволяет сделать процесс утилизации токсичных отходов свинцового производства технически и экономически целесообразным

Из проб были выделены тяжелые фракции и изготовлены полированные искусственные аншлифы (брикеты). Аншлифы изучались под микроскопом марки LEICA DM 2500P и в иммерсионных жидкостях. По результатам исследований выявлено, что в свинцовых шлаках содержится достаточно высокое количество соединений цветных металлов: оксида свинца до 0,7 % и оксида цинка до 8,5 % от весового количества шлака, что позволяет сделать процесс утилизации токсичных отходов свинцового производства технически и экономически целесообразным
