Abstract:

<em>The article deals with the tendencies of development of the Ukrainian lexico-semantic system, changes in the ways of enlarging its vocabulary while analyzing its word-formative processes. The author analyzes and describes the most productive ways of the Ukrainian word-formation. The questions of organization and setting of the Ukrainian word-formation norms are actual in modern linguistics. The task of scientific research is analysis of potential word-formation processes of the official-business style in the 20th – 30th years of the 20th century on the materials of the business langu

Abstract:

A 3D model of optimal contours phased development of oval-shaped open pit mines is proposed in the article. It is assumed that with enough accuracy the volumetric contour of the open pit mine is interpolated by an elongated elliptic hyperboloid. The calculation formulas for mineral resources are derived and optimal volumes of overburden are determined depending on the mining phase. In this case, the total number of mining phases is set in advance. The stripping ratio is used as a quality criterion of the optimization task. The problem of optimal control is solved using the Bellman function in

Abstract:

The article examines the issue of substantiation of filter selection methods to increase the efficiency of multi-level recurrent time-frequency segmentation in cognitive telecommunication systems. The main attention is paid to the analysis of signal filtering methods to improve the quality of data transmission in the dynamic conditions of the radio environment. The purpose of the article is to evaluate the effectiveness of various filtering methods for segmentation of ensembles of complex signals. The methods described in the article include Butterworth, Chebyshev, Bessel, Kaiser, elliptic, an

Abstract:

It is known, that existing public-key cryptography algorithms based on RSA and elliptic curves provide security guarantees accompanied by complexity. Based on this one can talk about the impossibility to solve problems of integer factorization and discrete logarithm. However, experts predict that the creation of a quantum computer will be able to crack classical cryptographic algorithms. Due to this future problem, the National Institute of Standards and Technologies (NIST), together with leading scientists in the field of cryptography, began an open process of standardizing public-key algorit

Abstract:

Changes in the priorities of the treatment of animals in the conditions of intense technology of production of livestock products are based on the necessity of wellbeing of animals. Therefore, there is a need of search for and broad introduction of generally accepted alternatives to surgery, which would use modern means of castration, particularly immunocastration. The study presents morpho-functional substantiation of practicability of using immunological castration in the conditions of industrial production of pork. At the same time, we studied immunological castration using Improvak on the

Abstract:

In the paper it is noted that the even distribution of seed and granules of mineral fertilizers inside the soil allows increasing their efficiency and obtaining a potential crop yield. For an even distribution of seeds of grain crops, herbs and fertilizer granules inside the soil, the use of a universal conical scatterer is proposed. The purpose of the study is to substantiate the parameters of a universal conical scatterer, which ensures an even distribution of metered bulk and hard-flowing materials, in particular, seed and granules of mineral fertilizers inside the soil.

Abstract:

A weak line inclusion model in a nonlinear elastic solid is proposed to analytically quantify and investigate, for the first time, the stress state and growth conditions of a finite-length shear band in a ductile prestressed metallic material. The deformation is shown to become highly focused and aligned coaxial to the shear band—a finding that provides justification for the experimentally observed strong tendency towards rectilinear propagation—and the energy release rate to blow up to infinity, for incremental loading occurring when the prestress approaches the elliptic boundary. It is concl

Abstract:

Substantiation of using non-circular plain shaped surfaces to increase the compactness of power plants is presented. The criterion of thermohydraulic compactness is justified, which takes into account the layout and arrangement of heat transfer elements and their thermohydraulic efficiency. To simulate heat movement and transfer processes in elements of power plants, the computational fluid dynamics method is used. Verification is carried out with available literature data, the discrepancy of results does not exceed 2.4 %. For single elliptical and plane-oval shapes, there is a local maxi
