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 ...

Vibration Signal Analysis For Rail Flaw Detection
2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS), 2019Rails are the foundation of rail transport, and any defects of the rails may directly affect the running state of the train or even lead to major safety incidents. However, the existing algorithms for rail crack detection are too expensive and difficult to perform on-line real-time monitoring.

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.

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 ...

[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.
