wingbeat การใช้

• The natural wingbeat of a bird was emulated by using bionics technology to decipher bird flight.
• _Owls are silent nighttime hunters whose feathers are designed to muffle the sound of their wingbeat.
• One can calculate the wingbeat frequency necessary for the insect to maintain a given stability in its amplitude.
• During the search phase the sound emission is coupled to respiration, which is again coupled to the wingbeat.
• While surveying for the owl plan, a biologist had heard the wingbeat of the marbled murrelet on the tree farm.
• However, the amplitude of the wingbeat does not always have to be the same on the left and right side.
• The clutch moves between grooves in the gearbox, to engage and disengage the wing muscles and also modulate the wingbeat amplitude.
• The Johnston s organ of fruit flies can be used to detect air vibrations caused by the wingbeat frequency or courtship song of a mate.
• Standing amid sword ferns at the forest floor one can sometimes hear the wingbeat of a tiny seabird above the canopy, some 200 feet up.
• But we can't say for sure which butterfly, on which wingbeat in which part of China is the cause of what future event.
• A hummingbird's ability to hover is due to its small mass, high wingbeat frequency and relatively large margin of mass-specific power available for flight.
• Flying birds of these species are shorter-necked and have a quicker wingbeat than their relatives, but they are often impossible to tell apart except by their calls.
• During the time interval ? " t " of the upward wingbeat, the insect drops a distance " h " under the influence of gravity.
• "' Vanellinae "'are any of various crested plovers, family Charadriidae, noted for its slow, irregular wingbeat in flight and a shrill, wailing cry.
• On Ulva, the inquisitive tuis amounted almost to a nuisance, they all wanted to approach the visitors and announce their interest and defend their territory with a peculilar loud wingbeat combined with melodious, but noisy, whistling.
• Even though haltere movement is controlled by separate muscles than the wings, because the wings are mechanically coupled with the halteres, changes in wingbeat frequency extend to the haltere-beat frequency as well, but haltere beat amplitude does not change.
• The pair's nest is on the Quabbin Reservoir in Massachusetts, but they come south to Connecticut for the winter, Mitchell said, adding that he knows Ross by his leg band and by " a very peculiar wingbeat ."
• A curve-tipped secondary on each wing is dragged against an adjacent ridged secondary at high speeds ( as many as 110 times per second slightly faster than a hummingbird's wingbeat ) to create a stridulation much like that produced by some insects.
• On April 10, 2009, Tyson L . Hedrick, Bo Cheng, and Xinyan Deng released their research findings on the dynamics of turning and maneuverability during flight pertaining to flying animals in the report, Wingbeat Time and the Scaling of Passive Rotational Damping in Flapping Flight.
• And if you take the copies of me from all those universes you can put together a nice motion picture where I am indeed " in " every stage of the wingbeat, flapping my way around town, with a delusional memory that perfectly matches the preceding frames in the picture you've spliced together.
