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

EM Purcell proposed three-linked swimmer 60 years ago as a hypothetical creature capable of swimming in highly viscous fluid. We have constructed a scaled model of this swimmer to investigate reciprocal and non-reciprocal swimming motion. The links were programmatically rotated by the interactive servomotors controlled by a microcomputer. Reciprocal motion of the links produced no net displacement illustrating the effect of scallop theorem. Experiments on non-reciprocal motion captured very important property suggested by theories: small stroke angles cause forward swimming and large stroke angles backward. We have measured non-dimensional displacement per cycle and compared with the theoretical predictions and found consistent. Surprisingly, in low-frequency region, flapping frequency of the links also play a role in determining swimming direction. The low-Reynolds number swimming is characterised by Stokes equation which is linear and time-independent. But frequency dependence in low-frequency region shows the breakdown of Stokes law with inertia.
