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: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

RESUMO

A laser speckle photography technique can nonintrusively measure thermal flow properties such as medium density, index of refraction or temperature. The laser specklegram records a line-of-sight or path-integrated information on these properties. For varying properties in a medium along the optical path, a mathematical technique called a tomography deconvolves cross-sectional information out of the projected measurement. The present work will outline the underlying principles of optical tomography and show how to apply it to the diagnostic technique of laser speckle photography. Comparisons of temperature measurements using a thermocouple probe against the temperature conversion from the specklegram data have been made for laminar flames. The speckle photography technique shows good potential as a new nonintrusive temperature measurement tool for various thermal flows.
