In [11], two objective metrics (3DWPM1 and 3DWPM2) derived from two definitions of surface roughness are proposed as the change in roughness between the reference and test meshes.
L r is the acoustic roughness level in dB, r RMS is the root mean square of rail roughness in μm, r 0 is the reference of rail roughness (r 0 = 1 μm).
The acoustic roughness level is given by the following expression: L_{r} = 10{ log }left( {r^{2}_{text{RMS}} /r^{2}_{ 0 } right), (7)where L r is the acoustic roughness level in dB, r RMS is the root mean square of rail roughness in μm, r 0 is the reference of rail roughness (r 0 = 1 μm).
The relationship between the surface roughness and adhesion is very complex.
The Euclidean and Hamming distances between any new test surface and the reference images in the database were used to predict the surface roughness of the test surface.
The change in roughness values is significantly smaller for the reference paperboard.
The reference sample S1 grown with H2-free condition possesses the coarsest surface with an RMS roughness of 1.028 nm.
The relationship between roughness and the antenna's radiation properties is obtained.
Run your finger along the edges of the joints between panels; roughness indicates residue left from masking tape.
The relationship between the magnitudes and road roughness is investigated.
