When a sinusoidal (ac) field is applied to a suspension containing nonlinear dielectric particles, the electrical response will generally consist of ac fields at frequencies of the higher-order harmonics. The situation is further complicated by an intrinsic dielectric dispersion which often occurs due to the surface conductivity or inhomogeneous structure of the particles. We perform a perturba...

This paper presents a harmonics extraction algorithm using artificial intelligent method for shunt active power filter. Generally, Fourier Transform is used to analyze a distorted wave from power line and low pass filter is used to eliminate the fundamental wave before each harmonics component is detected. This conventional approach is difficult to implement due to the complicated process. In o...

In this paper, for bus voltage control and to reduce power system harmonics, the active filtering technique is used in the mechanism of wind turbine control. Here a grid-connected doubly fed induction generator (DFIG) is considered in a wind turbine. In addition to harmonics that are related to the DFIG, a nonlinear load is also added to the system to simulate loads that produce more harmonics....

A new cepstrum-based technique is developed in order to provide an alternative means of estimating the harmonics-tonoise ratio in voice signals. The geometric mean harmonics-tonoise ratio (GHNR) is defined as the mean of the individual spectral (i.e. at specific frequency locations) harmonics-tonoise ratios in dB. A heuristic development of the method treats the harmonic spectrum (in dB) of voi...

When a sinusoidal ~ac! field is applied to a suspension containing nonlinear dielectric particles, the electrical response will generally consist of ac fields at frequencies of the higher-order harmonics. The situation is further complicated by an intrinsic dielectric dispersion, which often occurs due to the surface conductivity or inhomogeneous structure of the particles. We develop a perturb...

The two-harmonic FD-OCT method, where the quadrature components of the spectral interferogram are obtained by simultaneous acquisition of the first and second harmonics of the phase-modulated interferogram, is used for complexconjugate-resolved imaging of biological samples. The method is implemented using sampling of the phase modulated interferogram with an integrating detector array followed...
