Abstract:
The possibility of utilizing drill cuttings in the technology of building ceramics is investigated.Using the microscopic and X-ray spectral methods of analysis, the chemical and mineral composition and radiological properties of two samples of drill cuttings – waste gas drilling in the Poltava region – are determined.Using the bioindication method, it is established that the studied drill cuttings are phytotoxic and harm the environment, therefore, they need to be disposed of. According to the radioactivity, the cuttings are investigated, they belong to the materials of the 1st class, which allows using them without restrictions in the construction and production of building materials.The main ceramic-technological characteristics of the cuttings are determined. It is established that one of the cuttings in its composition is pre-burning and burning properties similar to clay rocks, the second cutting is unsintered psammite- aleuropelite material with a high content of calcium and magnesium carbonates, quartz and feldspar. The fundamental possibility of using the studied drill cuttings as the main raw material and mineral additives in the compositions of the masses to obtain wall ceramics with the necessary consumer properties is established.

Abstract:
The possibility of using conventional cutters, in which the super-hard materials Hexanit R acts as the material for the diamond knurling of shaft sections made of steel 10, has been investigated. It is recommended to use damaged replaceable tips with super-hard material as tool blanks, which requires either re-grinding or recycling. The possibility of restoring the working properties of such cutters by regrinding is established, provided that the core of the tool is precisely located relative to the axis of rotation of the workpiece. The design of tooling in the form of a mandrel for fixing the tool on a lathe is proposed. It allows flexible clamping of the tool to the workpiece. Design and operational processing parameters are recommended for diamond knurling using tips made of superhard Hexanit-R material: knurler radius –5 mm; clamping forces – 200 N; feed – 0.05 mm/rev; workpiece rotation frequency – 630 rpm. According to the knurling results, the roughness was Ra 0.8 μm when lubricated with I-20A mineral industrial oil. An increase in the number of passes greater than four did not lead to a significant improvement in surface roughness. No signs of wear, damage to the working surface of the tool after an operating time of 40 hours were found.

Abstract:
E-learning support system is a mandatory attribute of the modern educational process. What criteria laid down in its development depends largely on the effectiveness of further applications of the entire system. The evaluation of the training effect depends on various factors, each of which is determined by many interrelated criteria. In conditions when there are resource constraints (financial or time), the actual becomes the problem of determining the factors (criteria) that have the most significant impact on the effectiveness of e-learning system. The article offers step-by-step method of constructing a model that allows to represent the original set of criteria of evaluation of the training effect of the use of e-learning system in the form of appropriate level of influence grades. Introduces the concept of configuration vector and weight vector configuration, ranking models and based on them describe the procedure of finding the most substantive relationship between the criteria. Provides formulas to calculate appropriate weighting factors for current connections. An indicator of the importance of communication is the change of vector configuration, ranking models, and quantitative characterization of the dominant relations is defined as the difference between the weight coefficients of the respective vectors of the configuration options ranking of the analyzed models. The obtained results can be applied when developing holarchical models, support systems, e-learning, which allow us to quantitatively justify decisions regarding the choice of appropriate alternatives.

Abstract:
The article analyzes the general features of the implementation of SEO optimization, which allows to determine the main aspects of website promotion in search engines. It is indicated that the key goal of SEO should be to increase the position of the site in the ranking of search engines, as well as to increase the rate of conversion of users to regular customers. Separately, the article analyzes unethical optimization methods – black and gray types of SEO, which are used for web resources that are not designed for long-term existence. A study of the basic steps is done to configure HTTPS for the site, which can be used in the process of improving the operation of the web server. This allows to optimize the main and additional processor resources. Two methods of reducing the number of processor operations performed for each client are considered, which are the use of persistent connections, which allow processing several requests within one connection at once, and the reuse of SSL session parameters. The key stages of the methodology for optimizing and promoting the site in search engines have been developed and analyzed, accounting for which ensures increased site efficiency and get a configured and optimized configuration file. The proposed technique is implemented using the Nginx web server as an example, which uses a model with a fixed number of processes.

Abstract:
A systematic analysis of the occurrence of man-made emergencies due to a fire at the facilities is performed. It is established that in the event of fires, the gaseous medium in the premises of the facility serves as a means of transmitting hazardous effects to the facility. The object of influence may be maintenance personnel, technological equipment, units, the design of the room or the object itself. In this case, the state of the object of influence can be characterized by a certain scalar parameter, which in the general case represents the amount of loss (damage or risk) caused to the object by the influence of the danger object. It is shown that the scalar parameter is a certain functional of the states of the hazard object and the gas environment, characterizing the degree of emergency, numerically equal to the amount of losses caused to the object of exposure by the hazard object in the room. The possibility of preventing a man-made emergency due to a fire based on monitoring the parameters of the state of the gas environment in the premises of the facility is substantiated. It is noted that in real conditions there is no information about the indicated disturbances and the state of the hazard object. This is the main difficulty in reliably preventing a man-made emergency due to a fire in the premises of the facility. An experimental verification of the dynamics of the parameters of the state of the gaseous medium in the premises of an object during the combustion of alcohol, paper, wood and fabric in a model chamber is performed. The obtained data indicate that the real dynamics of the temperature, smoke, and CO content of the gaseous medium in the chamber upon ignition of the tested materials is not deterministic, but is clearly unsteady and non-linear with obvious signs of an unsteady trend and random disturbances. It is established that the nature of the random dynamics of the states of the gaseous medium at the time of ignition of materials changes dramatically. Moreover, these changes are of an unequal nature, depending on the type of combustible material. The obtained results indicate the possibility of preventing a man-made emergency due to a fire by means of operational monitoring of the parameters of the gas environment in the premises of the facility.
