Sentence examples for mean wing beat from inspiring English sources

To measure wing beats during whirring, we first measured the mean wing beat frequency for several birds by watching the video frame-by-frame.

Later studies by Gould and Heppner (1974) and Berger (1972) did not discover synchrony or phase relationships in geese flying in formation but they demonstrated that mean wing-beat frequencies differed little among individual birds.

Pairing an appetitive food odor (vinegar) with the visual stimulus results in a roughly 40% increase in the optomotor response (OMR), which is assessed by measuring the mean difference in wing beat amplitude across the two wings (ΔWBA) elicited by an impulse in yaw velocity, consistent with prior measurements [ 5].

During the downstroke the wing tip is bent upwards relative to the mean position during the wing beat (Fig. 8d) (corresponding to the pattern of the force generated during the wingbeat (Muijres et al., 2011)), indicating an increased effective camber.

Due to the relatively high fH immediately after flapping, sampling five heart beats directly after the last wing beat in a wing beat series took an average of 0.6 s.

The wing beat rate in O. nubilalis and O. scapulalis estimated from the repetition rates of pulses 1 and 2 (mean pulse interval  = 9.4 ms) was 53 cycles/s.

Extinction seems just one wing beat away.

Alcids, on the other hand, have proportionately shorter wings, high wing loadings, rapid wing beat rates and greater speed (45 55 miles per hour), and large flight muscles.

Clipping the wings of an insect that has fibrillar wing muscles increases the frequency of the wing beat, because reduction of the vibrating mass increases the resonant frequency.

Most importantly, the advance ratio, controlled either by enlarging the wing beat amplitude or raising the wing beat frequency, is the most significant factor in an ornithopter which mimics an insect.

"The steering muscles are responsible for driving the wing beat by deforming the thorax.
