It was found that with an increase of maximum aggregate grain size in concrete, the values of arithmetical mean height (Sa), the root mean square height (Sq) and skewness (Ssk) for the shotblasted surface also increase, while the value of the kurtosis (Sku) grows for ground surfaces and decreases for the shotblasted surface.
The surface's basic statistical parameters, such as RMS (root mean square) height ( left(sqrt{M_0}right) ), RMS slope ( left(sqrt{M_2}right) ), and RMS curvature ( left(sqrt{M_4}right) ), are the key parameters for the interface's behaviors, where M i is the ith radial moment of the surface spectrum [19, 20].
The root mean square heights (Sq) of the films are 17.1 and 18.6 nm, respectively.
The simulations give good results in terms of height envelopes, mean level, spectral shape, root-mean-square height for both free surface displacement and dynamic pressure inside the breakwater.
In this study, four soil surfaces with different roughness were designed, and three kinds of roughness parameters, root-mean-square height (rmsh), correlation length (cl) and rmsh/cl, of each soil surface were measured.
For a three-dimensional surface, the root-mean-square height of the surface (S q) is calculated by including all surface heights from the reference plane [30]; so in this case, the roughness obtained is more representative.
In the absence of coupling to actin and g = 0, the typical root-mean-square height fluctuation is h ≈ 3.6 nm.
Nevertheless, Rattanapitikon et al. [Rattanapitikon, W., Karunchintadit, R., Shibayama, T., 2003. Irregular wave height transformation using representative wave approach. Coastal Engineering Journal, JSCE 45(3), 489 510.] showed that the wave representation method could be used to compute the transformation of root mean square wave heights.
TPA-BODIPY exhibited obvious large grain separation, while CBZ-BODIPY showed more homogeneous and smooth morphology with low root mean square of average height (RMS) (0.23 nm).
