Application of Information Technologies and Programming Methods of Embedded Systems for Complex Intellectual Analysis

Abstract

An information model is outlined, which represents an intelligent system of metallographic analysis in the form of a set of subsystems, the interaction of which ensures the performance of metallographic analysis functions. The structure of the information storage subsystem for metallographic analysis is presented. The deployment model of an intelligent metallographic analysis system is proposed and described. The paper outlines the approach to the presentation of an expert subsystem for metallographic quality control of metals based on a neural network. The process of finding a close precedent in metallographic analysis with reference to a multilayer neural network is described. An intelligent metallographic analysis system is described, which based on proposed information model. A specialized software of an intelligent metallographic analysis system is presented. The functioning results of the developed system for processing images of steel microstructures to determine the steel quantitative parameters is presented.

Influence of melt treatment parameters on the characteristics of modified cast iron in the metallurgical industry using data mining methods

“…Based on the results of all nine experiments of the design matrix, using the well-known formulas [11] (these formulas were also used in [12][13][14][15][16][17]) and using the constants, all regression coefficients, their variances and root-meansquare errors were calculated, and then the confidence intervals for each group of coefficients at a significance level of α=0.05.…”

The development of an interactive database for assessing the ecological and geomorphic state of aquatic ecosystems

“…Such a database can become an important basis for creating an automated system for recording and monitoring the state of inland waterways of the Russian Federation [4]. It will be a key component of the automated interaction of participants in the process of vessel traffic along the inland waterways, including interaction with automated vessel traffic control systems and in the project of creating a unified multiservice network of basin authorities of the inland waterways and with other systems [5][6][7][8][9].…”

“…It is determined by possible migration and changes in the composition of services, as well as by the type of identification. If such situations arise, a reclassification is needed [8,9,10].…”

“…where n1 is the number of pairwise independent services in the first class involved in identification, m1 is the number of pairwise incompatible services in the first class involved in identification, n2 is the number of pairwise independent services in the second class involved in identification, m2 is the number of pairwise incompatible services in the second set involved in identification [7][8][9]. The main information available to the user at the first stage of the development of an intelligent database, as part of the triad, is the information contained in electronic maps.…”

Evaluation and Procedure for Estimation of Interharmonics on the Example of Non-Sinusoidal Current of an Induction Motor With Variable Periodic Load

“…higher harmonics (HH), as well as between the constant component and the fundamental harmonic. Based on the generalization of the best practices of international organizations involved in the regulation and modeling of non-sinusoidal processes with frequencies that are not multiples of the base one, the paper [3] defines a range of problems in the section of power quality indicators, which include malfunction of devices and control systems. One of the sources of interharmonics according to [4] can be electric motors.…”
