Aerodynamic Study of a NACA 64418 Rectangular Wing under Forced Pitching Motions

Fluids, 2021
The aerodynamic behavior of a pitching NACA 64418 rectangular wing was experimentally studied in a subsonic wind tunnel. The wing had a chord c = 0.5 m, a span which covered the distance between the two parallel tunnel walls and an axis of rotation 0.35 ...

Pitch Perception [PDF]

Attention, Perception & Psychophysics, 2008
This article is a review of the psychophysical study of pitch perception. The history of the study of pitch has seen a continual competition between spectral and temporal theories of pitch perception. The pitch of complex stimuli is likely based on the temporal regularities in a sound's waveform, with the strongest pitches occurring for stimuli with ...
