The correlation obtained in the end measures the trend, while the dimensional difference of different variables is removed in the calculation process, which is equivalent to Z-score standardization [30]. The Pearson correlation coefficient has mathematical meaning only when the two variables to be ...
In subject area:Computer Science Coefficient Alpha, in the context of Computer Science, refers to a statistical measure used to assess the internal consistency of items in a measurement. It indicates the degree to which the items are interrelated, allowing for the prediction of performance on one...
When two objects collide with each other, many forces come into play, which also means the application of various mathematical equations. Many of these laws were first derived by the same super popular scientist who is credited with numerous discoveries and derivations, meaning that he has a numb...
The measurements also show that the coefficient of restitution for a tennis ball can be as high as 0.9 for an oblique bounce on a slow court, meaning... R Cross - 《Sports Engineering》 被引量: 24发表: 2003年 Analysis of Impact Phenomena in a Tennis Ball-Racket System : Effects of Fra...
Friction drag, pressure drag and parasitic drag can each be expressed with dimensionless parameters. These quantities are also known asdrag coefficients. The meaning of these coefficients is quite analogous to other dimensionless similarity parameters such asReynolds number,Prandtl number,Nusselt number,Sch...
021 r-values.These data suggest that the more similar the two species are the higher the r-value is.We set 0.985 as the threshold of Genus,with the correlated recall being 75.824%,precision being 73.404%.This paper has important practical meaning in analyzing and modeling the relationship of ...
Finding COCO: Remembering the Meaning of Death and Life, in a Song Day after day we are consumed by technologies, media and information, invading our reality and influencing our social life. Though we may be conscious of this invasion, we allow it to prevail in our day life. We do not ...
They are frequent in tests and can be due to similarities in the meaning of some items, order effects, response format effects (e.g., Bandalos, 2021; Weijters et al., 2009) or the influence of specific identifiable factors beyond the common factor (Rodriguez et al., 2016a, 2016b). ...
(8.1). This definition is similar to the coefficient of friction for pure-sliding contact, but the physical meaning is different. Under pure-rolling conditions, circumferential velocity ω × r corresponds to the forward velocity v. However, during acceleration, circumferential velocity is higher ...
Clearly, the meaning of frictional coefficient during machining process in MD simulation is not a physical property of continuous materials anymore. The frictional coefficient represents the difficulty to remove material here. Qian et al. [56] studied the frictional coefficient of different single crysta...
