Some alternate vibrator signals
Geophysics, 1979Abstract The linear swept-frequency sine wave has been the only seismic vibrator drive signal seriously used in almost two decades of operational vibrator activity. However, there are other drive signals and alterations of this commonly accepted signal which offer improved peak-to-side lobe ratios on signal autocorrelations, as well ...

On Feedback Architectures With Zero-Vibration Signal Shapers
IEEE Transactions on Automatic Control, 2016The classical and recent feedback solutions for signal shapers are reviewed and critically analyzed in this paper. Based on this assessment, a new effective feedback control architecture is proposed, suitable for manipulation of weakly damped flexible structures.

Analysis of acoustic and vibration signals
1991In previous chapters we have seen how sound waves propagate as small pressure disturbances in a gas or liquid, or as changes in stress in a solid. Before we can study sound waves we need to be able to measure them. This is achieved by using a sensor (such as a microphone) which converts the pressure or stress change to an electrical form.

Monitoring of Grinding Burn by AE and Vibration Signals
Proceedings of the 6th International Conference on Agents and Artificial Intelligence, 2014The grinding process is widely used in surface finishing of steel parts and corresponds to one of the last steps in the manufacturing process. Thus, itâs essential a reliable monitoring of this process. In grinding of metals, the phenomenon of burn is one of the worst faults to be avoided.

[Meniscus signals in vibration arthrography].
Zeitschrift fur Orthopadie und ihre Grenzgebiete, 1987The technique of vibration arthrography (VAG) permits the non-invasive evaluation of internal derangements of the knee. Using the computer-assisted recording and analysis equipment which has previously been described, a major survey was conducted into the signal patterns present in subjects with symptomatic knee joints.

Copulatory Courtship with Vibrational Signals
2019Most research on sexual communication with substrate-borne vibrational signals has focused on the early stages of the reproductive process—mate localization and pair formation. Here, I report the results of a literature review that suggests that vibrational signals are commonly used in male–female interactions during and after copulation, either by ...
