this paper proposes a new method for parameter estimation of distorted single phase signals, through an improved demodulation-based phase tracking incorporated with a frequency adaptation mechanism. the simulation results demonstrate the superiority of the proposed method compared to the conventional sogi (second-order generalized integrator)-based approach, in spite of the dc-offset and harmon...

Introduction In France, GHM (French DRGs) have been used to fund the acute hospital sector since 2005, with extra per day for outliers or intensive care units, and specific payments for educational tasks, research and general interest. However, at present fees differ between for-profit and non-profit hospitals. But the law requires that fees must converge by 2012, with a 50% reduction in the di...

This paper presents an analysis-by-synthesis multimode harmonic coder (AbS-MHC) that employs new techniques to improve both the speech model accuracy and the parameter estimation robustness in the low rate harmonic coding framework. To improve the speech model accuracy, an enhanced frequency domain transition model is used in conjunction with the sinusoidal model based harmonic coding of voiced...

Abstract: In this paper, similar to the extension from intuitionistic fuzzy numbers (IFNs) to neutrosophic numbers (NNs), we propose the normal neutrosophic numbers (NNNs) based on the normal intuitionistic fuzzy numbers (NIFNs) to handle the incompleteness, indeterminacy and inconsistency of the evaluation information. In addition, because Heronian mean (HM) operators can consider capture the ...

By using a point canonical transformation starting from the constant-mass Schr\"odinger equation for isotonic potential, it is shown that semiconfined harmonic oscillator model with position-dependent mass in BenDaniel-Duke setting and same spectrum as standard can be easily constructed extended to shifted oscillator, which could result presence of uniform gravitational field. A further general...

In today’s technology world, Virtual personal assistants (VPA) have become very common and most people started making their homes smart using these VPAs. Although different companies assistants, Google Home Mini (GHM) will be our focus in this paper. The first device, Home, was released November 2016 then GHM after a year, October 2017. has many features such as playing music, setting reminders...

We present several variations on the harmonic Rayleigh–Ritz method. First, we introduce a relative harmonic approach for the standard, generalized, and polynomial eigenproblem. Second, a harmonic extraction method is studied for rightmost eigenvalues of generalized eigenvalue problems. Third, we propose harmonic extraction methods for large eigenvalues of generalized and polynomial eigenproblem...

A variational and perturbative treatment is provided for a family of generalized spiked harmonic oscillator Hamiltonians H = − d dx + Bx + A x + λ xα ,where B > 0, A ≥ 0 , and α and λ denote two real positive parameters. The method makes use of the function space spanned by the solutions |n> of Schrödinger’s equation for the potential V (x) = Bx + A x . Compact closed-form expressions are obtai...

In this work we focus on approximations of continuous harmonic functions by discrete harmonic functions based on the discrete Laplacian in a triangulation of a point set. We show how the choice of edge weights based on generalized barycentric coordinates influences the approximation quality of discrete harmonic functions. Furthermore, we consider a varying point set to demonstrate that generali...
