Webb24 feb. 2024 · Such measurement is not particularly limited, and may include cognitive and/or motor-related measurements. For example, referring again to PD, one such sign is bradykinesia, which is slowness of movement as described above. Useful measurements descriptive of bradykinesia include displacement, velocity, and acceleration of … WebbThe velocity of the compressional wave depends upon the elastic properties of the rock (matrix plus fluid), so the measured slowness varies depending upon the composition …

Slowness (s) is a quantity introduced in Seismology which is the reciprocal of velocity. Thus travel time of a wave is the distance that the wave travels times the slowness of the medium ( in seismology, it refers to different layers of Earth exhibiting different densities) Thus, Slowness = … Visa mer Measurements of interval transit time, designated $${\displaystyle {\Delta }t}$$, made during wireline logging are used to determine sonic velocities of the wallrock in boreholes.
