We report the measurements of correlations between event-by-event fluctuations of amplitudes of anisotropic flow harmonics in nucleus-nucleus collisions, obtained for the first time using a new analysis method based on multiparticle cumulants in mixed harmonics. This novel method is robust against systematic biases originating from nonflow effects and by construction any dependence on symmetry ...

The nonlinear characteristics of power electronic-based loads in a system contribute major role the harmonics’ injection and other quality disturbances. This affects supplied to consumers by distribution systems. Flexible AC transmission (FACTS) devices at level custom are used for an effective transfer. In addition these devices, filters play prominent paper aims analyze supply voltage time–fr...

A laser-based method to generate ultrashort pulses of synchrotron radiation in electron storage rings is coherent harmonic generation (CHG) using two undulators to produce coherent radiation at harmonics of the initial laser wavelength by microbunching. The bunching factor and thus the pulse intensity, however, decreases exponentially with increasing harmonic order. Echo-enabled harmonic genera...

The paper analyzes the effects of harmonics in wind turbines by presenting a useful technique to reduce the effects of harmonics. In this paper by using a harmonic model of wind turbine, and using a harmonic reduction technique, the power quality of network will be improved and the number of harmonics decrease. The technique is combination of wavelet analysis and active filters. The results sho...

This paper presents a critical voltage flicker detection based on a pair of inter-harmonics analysis method. The proposed algorithm can be applied in any crowded human place for human awareness purpose. Moreover, the correlation between pair of inter-harmonics and critical voltage flicker is described in details and the related formulas have been derived as well. According to simulation and exp...

Monaural sound source separation is the process of separating sound sources from a single channel mixture. In mixtures of pitched musical instruments, the problem of overlapping harmonics poses a significant challenge to source separation and reconstruction. One standard method to resolve overlapped harmonics is based on the assumption that harmonics of the same source have correlated amplitude...

This paper proposes a sliding-mode position estimation method for high-speed surface-mounted permanent magnet synchronous machines with LCL filter. The implementation of the filter aims at smoothing motor current and reducing iron loss caused by harmonic currents. Firstly, discrete-time model LCL-filtered drive system is developed. Based on developed model, observer proposed more robustness aga...

This extended abstract proposes a new method for onset detection using harmonic information on each note. Especially, this method is optimized on sudden attack instrument family. Even though there are some exceptions such as missing fundamentals in piano first octave notes or only existence of even harmonics in clarinet, each note in music has integer multiple harmonics in common. This method o...
