This letter addresses the problem of domain adaptation for task music source separation. Using datasets from two different domains, we compare performance a deep learning-based harmonic-percussive separation model under training scenarios, including supervised joint using data both domains and pre-training in one with fine-tuning another. We propose an adversarial unsupervised approach suitable...

the harmonic index h(g) , of a graph g is defined as the sum of weights 2/(deg(u)+deg(v)) of all edges in e(g), where deg (u) denotes the degree of a vertex u in v(g). in this paper we define the harmonic polynomial of g. we present explicit formula for the values of harmonic polynomial for several families of specific graphs and we find the lower and upper bound for harmonic index in caterpill...

The harmonic currents are generated by single phase nonlinear loads. The mirror surplus harmonic elimination method is used mostly because of its less computation. The Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) based methods can provide theoretically the highest quality output among all the PWM methods. In this paper SHEPWM model of a multilevel series connected voltage sour...

This paper is concerned with the acoustical analysis on sub-harmonic of glottal source in Mandarin tones. The methods used in this research are: 1) extracting glottal source of tones by inverse filtering; 2) analyzing subharmonic and spectrum tilt by FTT; 3) simulating the double peak pulse by 4 functions and describing the natures of them in both time and frequency domains. There are 3 conclus...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

This paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. The power filter integrates a passive power filter which is a RL low-pass filter placed in series with the load, and an active power filter which comprises an RL in series with an IGBT based voltage source converter. The filter is assumed...

this paper presents a new control methodology for active power filters that provide an adaptive online harmonic estimation with partial and selective harmonic reduction schemes, which has been implemented within an integrated controller. the proposed approach is to provide partial and selective reduction of those individual harmonics which exceed the recommended levels as set by regulatory bodi...

We performed a timing analysis of the 2003 outburst of the accreting X-ray millisecond pulsar XTE J1807–294 observed by RXTE. Using recently refined orbital parameters we report for the first time a precise estimate of the spin frequency and of the spin frequency derivative. The phase delays of the pulse profile show a strong erratic behavior superposed to what appears as a global spin-up trend...
