The main tools of internet marketing in public administration in the conditions of global digitalization

Formulation of the problem. The year 2020 convinced the whole world that the Internet is one of the best channels for transmitting information, selling goods and providing services, because thanks to its use, a certain part of businesses avoided bankruptcy, and some companies were able to increase sales and, most importantly, meet the needs of almost all spheres of life in society in crisis conditions.

THE OPTIMIZATION OF COMPUTER EQUIPMENT DURING THE MODERNIZATION OF THE UNIFIED SYSTEM OF CENTRALIZED CONTROL AND MEASUREMENTS OF THE SKS-7 NETWORK USING THE RESOURCES OF THE DATA PROCESSING CENTER

The architecture of the unified system of centralized control and measurements of the SKS-7 network is outdated, the technologies used to organize its work and implement data storage need to be updated and optimized, because the current state of the system causes a decrease in speed and performance, as well as a critical drop in reliability. Considering the factors, there is also a need to modernize the software and hardware of the IP protocol analysis and monitoring system.

Modeling of the modes of operation of wind energy installations in hybrid power supply systems

The article presents modern schemes for the organization of wind-solar power supply systems. Available approaches to managing the energy-dynamic process of operation of wind power plants as part of hybrid power supply systems are given, and modern research on this topic is given. The results of the development of a mathematical model of the energy-dynamic processes of the hybrid wind-solar power supply system, which includes wind power plants, solar panels, and a battery energy storage system. The universal structural diagram of such a system is substantiated.

Optimization of the infrastructure of the distributed information system of goods accounting

An existing goods accounting information system was assessed for possible infrastructure optimization. A various parts of the system were analyzed to improve infrastructure costs without having a significant degradation of non-functional requirements. Modeling of the optimized system was performed, and evaluation of the infrastructure costs was made. Several optimization directions were evaluated, analyzed and either recommended or rejected.

Optimization of Thermal Subsystem of Thermo Transducers for Measuring the Temperature of Gas Flows

The error of measuring the temperature of gas flows by contact methods consists of two main components: 1) the error that occurs in the process of measuring the physical quantity into which the temperature is converted (the error of the measuring means); 2) errors arising in the process of converting the temperature into a measured physical value using a thermo transducer.

Optimization of Hydrolysis in Ethanol Production from Bamboo

This research involved optimizing acid hydrolysis in the development of ethanol, a promising alternative energy source for restricted crude oil, from lignocellulosic materials (bamboo). The conversion of bamboo to ethanol can mainly be accomplished through three process steps: pretreatment of bamboo wood for the removal of lignin and hemicellulose, acid hydrolysis of pretreated bamboo for the conversion of cellulose into sugar reduction (glucose) and fermentation of sugars into ethanol using anaerobic Saccharomyces cerevisiae.

Optimization of Isocratic Ion Chromatography Methods for Simultaneous Inorganic Anions and Carboxylic Acids Determination

As a part of preliminary studies, the possibility of quantitative oxidation of aldehydes to carboxylic acids and their determination by isocratic ion chromatography with conductometric detection has been tested.

COMPARATIVE ANALYSIS OF MONOLITHIC AND CYCLIC NOISE-PROTECTIVE CODES EFFECTIVENESS

Comparative analysis of the effectiveness of monolithic and cyclic noise protective codes built on "Ideal Ring Bundles" (IRBs) as the common theoretical basis for synthesis, researches and application of the codes for improving technical indexes of coding systems with respect to performance, reliability, transformation speed, and security has been realized. IRBs are cyclic sequences of positive integers, which form perfect partitions of a finite interval of integers. Sums of connected IRB elements enumerate the natural integers set exactly R-times.

A Modeling Study of Operating Conditions and Different Supports on Fe-Co-Ce Nanocatalyst and Optimizing of Light Olefins Selectivity in the Fischer-Tropsch Synthesis

This study demonstrates the effect of operating conditions (Red-GHSV, inlet H2/CO, Oprat-GHSV) and the effect of Fe-Co-Ce nanocatalyst support. A statistical model using the response surface methodology (RSM) was applied with the target of achieving higher olefins selectivity in Fischer-Tropsch synthesis, which indicates the interaction effects of factors. The conditions under which three objectives optimization for maximizing olefins and minimizing paraffins and methane were determined.

Application of Response Surface Method to Copper Cementation by Metallic Aluminum Particles

In the present study, the interactive effects of the process variables containing copper concentration, temperature, and time on the efficiency of copper cementation by metallic aluminum particles were examined by using response surface methodology (RSM). It was observed that the efficiency of cementation increased with an increase in the initial concentration of copper, temperature and time. The multiple regression analysis to the experimental data was applied to see the interactive effects of process variables. The second-order polynomial equation was obtained.
