Also, the nanoindentation hardness decreased, while the coefficient of friction and scratch adhesion strength increased.
Note that the range of the variable Diversity is 0.057 to 0.213 in our sample while the coefficient of Diversity ranges between −21.132 to −2.195 in our regression models.
As the sulphate concentration was increased, hardness of the film generally increased at first and then decreased, while the coefficient of static friction of the film decreased.
The maximum in hardness coincides with the minimum in wear, while the coefficient of friction is fairly constant at 0.7 0.8.
The coefficient of internal friction for the seeds was 0·31, while the coefficient of friction on plywood, mild steel sheet and galvanized sheet were 0·32, 0·30 and and 0·23.
With the increase of initial velocity, the rebounding velocity first increased to a maximum value and then dropped, while the coefficient of restitution first decreased almost linearly and then levelled off at a lower level.
The results show that while the coefficient of performance (COP) is comparable to a conventional bulk element TE cooler, the cooling power density drops off dramatically with a decrease in stacking angle of the legs.
The normal or lognormal distribution of variables has no effect on the failure probability, while the coefficient of variation (COV) of random variables would greatly influence the failure probability.
It was found that the coefficient b was related to the hydrodynamic conditions, while the coefficient a was affected by the cell geometry, electrolyte concentration and the membrane properties.
At these resolutions, all the five coefficients of dependent variables characterizing landscape compositions attain the maximum value, while the coefficient of the autocorrelation of LST is reduced to minimum.
In the range of operating test conditions investigated the pressure ratio varies from 1.54 to 3.75, the cooling capacity of the system varied from 37 W to 374 W, while the coefficient of performance (COP) ranged between 1.04 and 5.80.
