Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
To avoid the so-called cold-shutCold shutdefectDefects, the relationships among the proposed factors, such as shape factorShape factor, mold constantMold constant, and critical flow rate, were built up to construct the designing rules for the bottom ingate. An aluminumAluminum knuckle casting was cast in various initial mold temperaturesTemperature to obtain the critical filling flow rate controlled by the cross-sectional area of the bottom ingates with a constant velocity. Using the computational fluid dynamic package, the various magnifying sizes with the same shape as the knuckle castings were modeled, and the maximum critical filling time could be found. Based on the proposed shape factorShape factor modifying Chvorinov’s ruleChvorinov’s rule, the so-called critical mold constantMold constant (Bcold) and the shape factorShape factor (Spcold) were introduced in this study. From the proposed relationship, the rule of designing the critical bottom ingate size with the minimizing flow rate could be achieved to avoid cold-shutCold shutdefectsDefects.
