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

Using the Ito − Tanimoto method, Copeland has shown that the equation of “mild slopes” can be transformed into a system of two simultaneous first-order hyperbolic equations, and this makes it possible to expand the area covered by the calculation significantly and to allow for a reflected wave in the modeling of wave propagation in a shelf area with port structures and facilities. This paper presents a generalization of the Ito − Tanimoto method for the “mild-slope” equation where slowly changing currents are taken into account, which produces a fuller system of simultaneous hyperbolic equations. In the case of deep water, we compare a numerical solution of the system for the heights of harmonic waves propagated down and up the stream with an earlier analytical solution. The system of equations derived in the report is also tested using the data of experiments by Thomas for constant depth and of experiments by Sakai for variable depth. Results of the numerical modeling of wave propagation in a bay with a mouth of a river flowing in it are shown for a two-dimensional case.
