The Effects of dc Current Polarization on Cochlear Harmonics

The Journal of the Acoustical Society of America, 1972
The effects of dc polarization of the cochlear partition were observed on harmonic distortion components in microphonics. The qualitative effects of negative polarization (scala vestibuli negative) were quite consistent and similar to those observed in the polarization of intermodulation distortion components.

Alternating current sensor with second-harmonic detection

Applied Optics, 2000
We describe a novel optical sensor based on the Faraday effect for measuring ac. The sensing element is a piece of material of high Verdet constant placed between polarizers. When the angle between the polarizers differs by 45 degrees, a signal of twice the frequency of the ac is generated--in addition to the usual signal with the same frequency as the

The calculation of harmonics in rectified currents

Journal of the Institution of Electrical Engineers, 1930
The classical mathematical method of calculating the wave-form of rectified currents is applicable to rectifiers whose volt-ampere characteristic consists of two interesting straight lines. It is based on the observed fact that there is for each rectifier a conducting phase and an insulating phase.

Current International Harmonization Efforts

2009
Efforts towards international cooperation or harmonization can occur at varying levels – at the level of technical and scientific requirements, of dossier format and content, or of assessment and review practices. Three contrasting models for regional cooperation in drug regulation harmonization, the corporate, populist, and cooperative, are described ...

Valuation of harmonic current injections

2002
The number of power electronic and distorting loads, continue to grow at a rapid pace. Accompanying this growth in distortion sources is an increased sensitivity of certain types of loads to harmonic distortion, and poor power quality in general. The result is greater variance in the value loads place on a harmonic free supply, and therefore what they ...

Harmonic Currents and Canonical Complexes

2001
In the present chapter we establish a Hodge theory for the complexes In particular, we prove a decomposition of the spaces which resembles the Hodge decomposition on compact Riemannian manifolds. The method can be explained easily in the classical framework. Let (M,g) be a compact Riemannian manifold with Hodge-Laplacian on p-forms.
