[Meniscus signals in vibration arthrography].

Zeitschrift fur Orthopadie und ihre Grenzgebiete, 1987
The 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.

Sonification of knee-joint vibration signals

Proceedings of the 22nd Annual International Conference of the IEEE Engineering in Medicine and Biology Society (Cat. No.00CH37143), 2002
Sounds generated due to rubbing of knee-joint surfaces may be a potential tool for noninvasively assessing articular cartilage degeneration. In this paper, an attempt is made to perform computer-assisted auscultation of knee joints by auditory display (AD) of the vibration signals (also known as vibroarthrographic or VAG signals) emitted during active ...

Copulatory Courtship with Vibrational Signals

2019
Most 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 ...

Method of Generating Vibration Test Signals

Measurement Techniques, 2017
Possible ways of implementing vibration test signals are described. A method for generating such signals is proposed by adjusting the amplitudes of the individual harmonic components of the vibration signal. The results of modeling are presented.

Nonlinear vibration characterization by signal decomposition

Journal of Sound and Vibration, 2007
Abstract Methods for nonlinear vibration characterization by decomposing dynamic responses using the Hilbert–Huang transform and a sliding-window fitting technique are presented. Numerical results show that Hilbert–Huang transform can be used for decomposing nonlinear/non-stationary signals in order to reveal and estimate nonlinear effects.

Signal analysis for rotating machinery vibrations

Pattern Recognition, 1975
Abstract A novel method is proposed for the purpose of characterizing repetitive vibration signals. This consists in decomposing the signal into periodic—not necessarily harmonic—components. Two parameters are then sufficient for the description of each component. The appropriate signal processing technique is based on time domain averaging.
