Such differences may have something to do with local conditions — certain soils or fill can amplify the seismic vibrations — but the orientation of the fault also plays a role, said Robert B. Herrmann, a geophysicist at St . LouisUniversity who is among those analyzing the aftershock data.
Each of these four types corresponds to a specific range of phase angles between the streamwise and transverse vibrations defining the orientation of the trajectory and the direction of orbiting.
An LQG method is proposed for vibration sensor location and orientation optimization.
Courtship in Drosophila consists of a stereotyped sequence of behaviors including orientation, wing vibration, tapping with the forelegs, abdomen curling, and copulation (Spieth, 1974).
Irregular vibrations along several orientations reduce the energy conversion and the harvester efficiency.
Therefore the presence of irregular vibrations along several orientations reduces the energy conversion and the harvester efficiency.
To this end, in the paper a method of tool orientation determination for vibration and deformation reduction during ball-end milling of flexible impeller blades is proposed.
Finally, the effects of damage orientation on the vibration responses of a plate are numerically investigated, and the numerically simulated damage identification tests are conducted to verify the present damage identification theory.
Courtship vigor is defined as the total time the male spends courting, calculated from the first instance of orientation and wing vibration.
The courtship behavior of Drosophila has been studied in far greater detail and involves a series of steps: orientation, following, tapping, wing vibration or "singing," and licking (of the female genitalia), followed by tail curling and copulation [ 58].
