The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

An approximate practical method of calculation nonlinear of the Khaskind -Newman hydrodynamic loads, acting on the ship's hull rolling on the waves with finite amplitude, is grounded. In so doing, the effects of variation of wetted part of the ship's surface and an anharmonicity of the velocity field on it are taken into account. Determination of loads is generally reduced to calculation of hydrodynamic coefficients of ship's sections in their instant positions, namely, the attached masses and damping coefficients. To determine the instant hydrodynamic coefficients in wide range of shapes of ships' sections the multiparameter conformal mapping in the parametric plane and the Ursell technique for the determination of the velocity potential in this plane are used. The parameters of conformal mapping and the amplitudes of hydrodynamic singularities are derived by the least-squares method. The results of comparative calculations for hydrodynamic coefficients of typical ship's sections, ship's sections pitched up to 40◦, sections with bilge keels and bulbous SWATH ship's sections are presented. The agreement of these results is estimated in general as satisfactory and good.
