The Energy Processing by Power Electronics and its Impact on Power Quality

International Journal of Renewable Energy Development, 2012
This paper discusses the electrical architectures adopted in wind turbines and its impact on the harmonic flux at the connected electric network. The integration of wind electric generators with the power grid needs energy processing by power electronics.

Harmonic Distortion in Cochlear Models [PDF]

The Journal of the Acoustical Society of America, 1957
The envelope over the train of waves traveling along the cochlear partition is asymmetrical: the distal slope being steeper than the proximal one [G. von Békésy, J. Acoust. Soc. Am. 19, 452 (1947)]. In experiments on models, this asymmetry was seen to increase with intensity.
