To improve the coherence of the aeroelastic results, a study on structural mistuning
and intake geometry will be carried out to understand and quantify the sensitivity of occurring instability mechanisms.
These blade-to-blade discrepancies are called mistuning
, which is typically small, but can lead to concentrated vibration in a small region of the structure.
This phenomenon is usually called mistuning
Showing topographical plots of MMN responses to the mistuning
deviants, which elicited the strongest and most consistent MMN responses in the tested sample in the EEG (a), MEG magnetometers (b), and MEG gradiometers (c).
Effect of mistuning
are omitted and therefor system is considered with fully cyclic symmetry.
Specifically, 5 of the 6 musical features are aspects of the musical sound that elicit different MMNs depending on levels of musical expertise: pitch mistuning
, intensity, timbre, sound-source location, and rhythm [54-56].
The antennas can also be tuned to operate at different frequency bands or to compensate the user-originated impedance mistuning
. The antenna is matched to have an over-coupled impedance behavior (see Figure 6(b)).
Vibrato may contribute to the tendency of listeners to allow for more mistuning
from singers than from violinists, but researchers have yet to test for that possibility." More research could also address a question e-mailed by reader Nathan Meleen, who asks how speakers of tonai languages, which use changes in pitch to distinguish between otherwise identical words, might fare in identifying off-key crooning compared with speakers of nontonal languages.
These blades have design errors--too low the first-mode mistuning
from the 2nd rotational harmonic excitation.
Afterwards the 11 presenters demonstrated different HCF problems and their mitigations based on either the traditional redesign approaches or advanced solutions, such as frictional damping technology or intentional blade mistuning
The adjustment of the parameter [DELTA]l was used to tune the mistuning
of the resonant frequencies of coupled single-mode resonators that are equivalent to the dual-mode resonator.
In this regard Tenney invokes the mechanism of tolerance, familiar from cognitive psychology, which holds that - within a certain tolerance range, or range of frequencies - some slight mistuning
is possible without altering the harmonic identity of an interval.
