In the context of non-stationary sinusoidal modeling, this paper introduces the generalization of the derivative method (presented at the first DAFx edition) for the analysis stage. This new method is then compared to the reassignment method for the estimation of all the parameters of the model (phase, amplitude, frequency, amplitude modulation, and frequency modulation), and to the CramérRao b...

The susceptibility amplitude ratio in the neighborhood of a uniaxial Lifshitz point is calculated at one-loop level using field-theoretic and ǫL-expansion methods. We use the Schwinger parametrization of the propagator in order to split the quadratic and quartic part of the momenta, as well as a new special symmetry point suitable for renormalization purposes. For a cubic lattice (d = 3), we fi...

â  using of prediction models is one of the methods of financial performance prediction. financial ratios are employed as predictive variable in prediction models. the main purpose of this study is to compare the incremental information content of accrual and cash ratios for prediction and evaluation of the financial performance of business entities by data mining models. in align with research...

The analysis of amplitude parameters of the diaphragm mechanomyographic (MMGdi) signal is a non-invasive technique to assess respiratory muscle effort and to detect and quantify the severity of respiratory muscle weakness. The amplitude of the MMGdi signal is usually evaluated using the average rectified value or the root mean square of the signal. However, these estimations are greatly affecte...

The popular impulse approximation is applied to the Richtmyer-Meshkov problem for continuously strati ed uids through the use of a model due to Sa man and Meiron. The predictions of the late time growth rate of the interface and interfacial circulation from a numerical implementation of the model are compared with calculations from the nonlinear Euler equations. It is shown that for weak incide...

To determine the polarization character of gravitational waves, we use strain data from GW170814 binary black hole coalescence event detected by three LIGO-Virgo observatories, extracting wave signal amplitude ratios directly those data. Employing a geometric approach that links to properties, find there is range source sky locations, partially overlapping LIGI-Virgo 90% credible for which vect...

Open-flavor strong decays are mediated by qq̄ pair production, which is known to occur dominantly with P0 quantum numbers. The relation of the phenomenological P0 model of these decays to “microscopic” QCD decay mechanisms has never been clearly established. In this paper we investigate qq̄ meson decay amplitudes assuming pair production from the scalar confining interaction (sKs) and from one gl...

The lifetime of a stored beam due to the Touschek effect is calculated for arbitrary ratios of beam height to beam width. A variation of the beam envelopes is taken into account, i. e. the derivatives of the horizontal and vertical amplitude functions and dispersions are included. The calculation is done for arbitrary energies in the rest frame of the colliding particles.

We present a technique to derive -quadrature amplitude modulation (QAM) signals from quaternary phase-shift keying (QPSK) constellations when = 2 and is an even number. By utilizing QPSK Golay sequences, we have constructed -QAM sequences with low peak-to-mean envelope power ratios. Several upper bounds for these -QAM sequences were derived.

Some universal amplitude ratios appropriate to the φ2,1 perturbation of the c = 7 10 minimal field theory, the subleading magnetic perturbation of the tricritical Ising model, are explicitly demonstrated in the dilute A3 model, in regime 1. AMS classification scheme numbers: 82B23, 81T40
