Development of Software and Hardware Complex based on Theoretical Modeling and Experimental Study of Linearly Extended Energy Facilities on their Technical Condition

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, […]

Neural Network Architecture Development for Time Series Forecasting

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 […]

Application of Spectral Clustering Methods in Pipeline Systems Graph Models

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 […]

Technical Quality Analysis of Trunk Pipeline

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 […]

Analysis of Structure and Tectonics Based on Architecture and Design

Abstract The article describes the problem of attention increase to descriptive analysis of world design products in educational and industrial, in creative and design practice. The study revealed the rules according to which the products of designer’s creative activity are formed. To address the issues of studying design and tectonics using the example of compositional […]

Cracks Pattern Formation and Thermomechanical Fatigue in Die Steels

Abstract Investigations are given of the influence of thermal, thermochemical treatment of die steels on the development of thermomechanical fatigue cracks depending on the temperature-force effects characteristic of hot deformation dies. As the evaluation criteria for the thermomechanical fatigue resistance of surface hardened die steels, the moment of nucleation, their quantity, and the depth of […]

Chip-Based Radio-Frequency Tag

Abstract The article is devoted to the problem associated with the operation of radio frequency tags within the UHF range in close contact with various media. The principle of RFID system operation is explained, design features and UHF RFID tag reading for metal objects are considered. They considered one of the possible options to improve […]

Qualitative Assessment of Soils Based on Hydrophysical Parameters

Abstract A qualitative assessment of the main types of zonal soils is necessary to assess the potential fertility of agricultural land. Soil bonitet analysis is used for cost-effective agriculture, determining the resource potential of agricultural land. Despite the many works devoted to soil evaluation, the definition of objective criteria and soil rating scales have not […]

Removal of Hardening Salts by Nanofiltration Composite Membranes

Abstract For removal of hardness salts, composite nanofiltration membranes with a “nylon-PS” polystyrene (PS) surface layer, a cellulose acetate (AC) surface layer on a nylon “nylon-AC” substrate, and a cellulose acetate surface layer on a polytetrafluoroethylene (PTFE) substrate were obtained “PTFE-AC”. To increase the retention capacity, several layers of polymer particles were applied to the […]
