DEVELOPMENT OF A MODEL FOR THE PRODUCTION OF METAL-POWDER COMPOSITIONS BASED ON CO-CR ALLOYS BY ELECTROEROSIVE DISPERSION

Abstract. The main requirement for powders for additive 3d technologies is the spherical shape of theparticles. Such particles are most compactly packed into a certain volume and ensure the "fluidity" of the powder composition in the supply systems of the material with minimal resistance. The wide use of the EED method for processing metal waste into powders for the purpose of their reuse and application in additive technologies is hampered by the lack in the scientific and technical literature of full-fledged information on the effect of the initial composition, regimes and media on the properties of powders and technologies of practical application. Therefore, in order to develop technologies for the reuse of electroerosive powders and to evaluate the effectiveness of their use, complex theoretical and experimental studies are required. The aim of the work was to develop a model for the production of metal powder compositions on the basis of Co-Cr alloys by electroerosive dispersion. Based on the results of the conducted studies, it has been established that the optimum parameters for the process of obtaining powder materials by the method of electroerosive dispersion of butyl alcohol are: capacitance of discharge capacitors 48 μF, voltage on electrodes 100 V, repetition rate of pulses 120 Hz

LINGUISTIC CONCEPTS “HOUSE/HOME” IN WORKS OF ENGLISH AND RUSSIAN WRITERS

Abstract. The article deals with the comparative analysis of the linguistic concepts “house/home” and “dom”(house/home in Russian) represented in the English and Russian literature on the basis of the following literary works: “Childhood”, “After the ball” by Leo Tolstoy, “October on the Train”, “My mother and Music”, “Tale of Sonechka” by Marina Tsvetaeva, “Three sisters”, “The Man in the Case” by Anton Chekhov, “An Ideal Family” by Katherine Mansfield, “The house with the green blinds”, “The House of Eld”, “New Arabian Nights” by Robert Louis Stevenson, Jane Eyre by Charlotte Brontë. The analysis is carried out on the level of linguistic concept structure. As a result, it can be summarized that on the level of dictionary analysis Russian “dom” has less meanings that “house/home” in English while on the level of literary works analysis, Russian “dom” is broader in meaning and connotation.Keywords: concept, house/home, lexeme, seme, artistic worldview, cognitive approach

Some properties of vague graph structures

A graph structure is a generalization of simple graphs. Graph structures are very useful tools for the study of different domains of computational intelligence and computer science. A vague graph structure is a generalization of a vague graph. In this research paper, we present several different types of operations including cartesian product, cross product, lexicographic product, union, and composition on vague graph structures. We also introduce some results of operations.Publisher's Versio

Edge Regular Complex Neutrosophic Graph Structure and it is Application

A modified version of a Neutrosophic Set (NS), a Complex Neutrosophic Set (CNS) offers a more accurate description of ambiguous situations than established fuzzy sets (FSs). It is widely applied in uncertain control. This study offers the idea of Single-Valued Complex Neutrosophic Graph Structure (SVCNGS)
