Abstract This article presents the results of experimental studies of a fully developed turbulent air flow in a round pipe with superimposed flow pulsations. The time-averaged static pressure losses and instantaneous velocity values on the pipe axis were measured in a wide frequency range of superimposed harmonic pulsations of the air flow in three modes […]
Abstract The article presents the structural diagram of the static mathematical model for vapor compression cooling system (VC CS), which is the sequence of units with known transfer functions of thermal processes and the static mathematical model that allows to calculate the static characteristics of the considered CS in the form of cooling capacity dependence […]
Abstract This paper discusses the problems of accounting for the amount of oil in tanks. Various types of oil storage tanks, as well as instruments for controlling its amount, are analysed. Based on the studies conducted, the most suitable level gauges for use in various types of oil tanks were identified. Although visual inspection may […]
Abstract The article presents a developed algorithm for the manipulator drive control system using a processor. This algorithm consists of three parts: – the functioning algorithm of the manipulator drive control system, in order to ensure the movement of the workpiece along a given path; – the functioning algorithm of the manipulator drive control system, […]
Abstract The article substantiates the need for introducing into the international scientific circulation the author’s definition of the legal and psychological phenomenon of “safe computer attack”, which is proposed to understand the state of the subjects of information legal relations that are aware of the danger of violation and the importance of ensuring the security […]
Abstract This article discusses the implementation of a comprehensive program for the technical re-equipment of oil and gas production. The methods of combating the formation of ARPD in wells, intensive introduction of new equipment and technology, automation tools and automated production control systems into production were analyzed and reviewed. Based on the analysis, it was […]
Abstract One of the key areas of development of the Russian economy is to increase energy efficiency, according to the Energy Strategy of Russia for the period until 2030. Our country has a huge potential for energy conservation, and its implementation will significantly reduce the energy intensity of the country’s GDP without increasing energy capacity, […]
Abstract The paper reveals the results of studies on the development of neural network architecture for time series forecasting. Three types of neural networks were investigated: radial network, convolutional network, and multilayer perceptron. The main objective of this study is to identify, based on a comparative analysis, the architecture of a neural network, which is […]
Abstract Among the many tasks on graphs, studies related to partitioning an initial graph into a predetermined number of connected disjoint components have found wide practical application – graph clustering, for example, is used in computer networks, transport, pattern recognition, and in many other areas. The decomposition methods of graph structures make a significant contribution […]
Abstract The current level of technology development concerning technical, informational and organizational services in the field of the linear part of trunk pipeline technical condition diagnostics has significantly increased the control reliability and productivity [1]. Thus, tens of thousands of defects, including those of an operational nature, are detected annually only via in-line inspection. Since […]
