In this paper we propose a model-based approach to instantaneous pitch estimation in noisy speech, by way of incorporating pitch smoothness assumptions into the well-known harmonic model. In this approach, the latent pitch contour is modeled using a basis of smooth polynomials, and is fit to waveform data by way of a harmonic model whose partials have time-varying amplitudes. The resultant nonl...

This paper is a survey of the inverse scattering problem for time-harmonic acoustic and electromagnetic waves at fixed frequency. We begin by a discussion of “weak scattering” and Newton-type methods for solving the inverse scattering problem for acoustic waves, including a brief discussion of Tikhonov’s method for the numerical solution of ill-posed problems. We then proceed to prove a uniquen...

In this paper we propose a postprocessing technique for a spectrogram diffusion based harmonic/percussion decomposition algorithm. The proposed technique removes harmonic instrument leakages in the percussion enhanced outputs of the baseline algorithm. The technique uses median filtering and an adaptive detection of percussive segments in subbands followed by piecewise signal reconstruction usi...

The radial Schrodinger equation for a spherically symmetric potential can be regarded as a one-dimensional classical harmonic oscillator with a time-dependent spring constant. For solving classical dynamics problems, symplectic integrators are well known for their excellent conservation properties. The class of gradient symplectic algorithms is particularly suited for solving harmonic-oscillato...

Abstract Predicting the forced responses of nonlinear systems is a topic that attracts extensive studies. The energy balancing method considers net transfer in and out system over one period establishes connections between normal modes (NNMs). In this paper, we consider across multiple harmonics NNMs for predicting resonances. This technique constructed by combining mechanism with restrictions ...

This article presents an 11-level operation of the WE (Wee)-Type inverter. The topology employs a single DC-source, has reduced number components, and exhibits boosting capability. A voltage balancing algorithm is proposed where inverter’s redundant states are employed to maintain auxiliary DC-link voltage. It shown that with control algorithm, link preserved at half primary voltage, possible f...
