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

要約

Certain mathematical models of wave dynamics of the shelf zone are presented. Numerical solutions demonstrating new characteristic effects of the interaction between nonlinear water waves and the bottom topography are obtained. Nonlinear dispersive asymptotic approximations describing the propagation of waves above the bottom topography are obtained on the basis of an exact two-dimensional formulation that includes the Laplace equation for the velocity potential, nonlinear conditions on the free surface and conditions at the bottom surface. This is done on the assumption that dispersion parameter β and gradient γ of the bottom surface are small, whereas nonlinearity factor α is assumed to be arbitrary, unlike the extensively employed traditional approximate theories. A nonlinear model for investigating the motion of saline sea water and also the restructuring of an irregularly shaped bottom by means of waves propagating above it are also presented. The corresponding initial- and boundary-value problem is solved by the method of finite differences for specified semisinusoidal-type pulses repeatedly generated at the inlet. In addition, this problem is analyzed on the basis of the KdV equation with a specified inlet soliton. Numerical results are presented and analyzed.
