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

ABSTRAKT

This paper focuses on some of the shortcomings of the discrete ordinates method. Some are crucial to the solution accuracy, while others affect the efficiency of the solution procedure. The shortcomings reviewed in this paper are the ray effect, excessively long computational times in optically thick media, effects of spatial differencing schemes, and false scattering. A recent proposal for a more efficient treatment of the in-scattering term, that reduces the computational times for optically thick scattering media, is described. A study of several spatial differencing schemes, that showed that the diamond scheme can produce physically unrealistic solutions for some multidimensional computations, is discussed. Recommendations for a better differencing scheme that would also reduce false scattering are given.
