Abrupt depth transitions (ADTs) have been shown to induce the release of bound waves into free waves, which results in spatially inhomogeneous wave fields atop ADTs. Herein, we examine role free-wave generation and spatial distribution higher-harmonic components onset breaking for very steep periodic upon interaction with an ADT. We utilise a Smoothed Particle Hydrodynamics (SPH) model, making ...

We present a Bayesian analysis method that estimates the harmonic structure of musical instruments in music signals on the basis of psychoacoustic evidence. Since the main objective of multipitch analysis is joint estimation of the fundamental frequencies and their harmonic structures, the performance of harmonic structure estimation significantly affects fundamental frequency estimation accura...

Different transformer models have been developed in the past for steady state and transient analysis of power systems. Some of these models have nonlinear components to take into account the magnetic core saturation characteristics so that harmonic generation can be simulated. Case studies based on these models are presented to demonstrate the harmonic generation behaviors of transformers under...

The paper presents the DQ axis with Fourier analysis (DQF) algorithm to identify harmonic quantities for hybrid power filters. This algorithm is a combination of the advantages of DQ axis method and sliding window Fourier analysis (SWFA). This paper also presents the harmonic elimination by using the DQF algorithm for both three-phase balanced and unbalanced systems. The results show that the u...

A harmonic coder extracts the harmonic components of a signal and represents them efficiently using a few parameters. The principles of harmonic coding have become quite successful and several standardized speech and audio coders are based on it. One of the key issues in harmonic coder design is in the quantization of harmonic magnitudes, where many propositions have appeared in the literature....

In this paper we propose a method to estimate and transform harmonic components in wide-band conditions, out of a single period of the analyzed signal. This method allows estimating harmonic parameters with higher temporal resolution than typical Short Time Fourier Transform (STFT) based methods. We also discuss transformations and synthesis strategies in such context, focusing on the human voice.
