Seven common normalization strategies are compared for unstopped citation tone F0 in the Chinese dialects of Shanghai, Cantonese, Fúzhōu and Zhāngzhōu. A z-score normalization is shown to give clearly superior clustering as quantified by normalization index, but no indication of superiority for a prior log transform of F0 is found.

The recently published articles in the Iranian Journal of Biotechnology inspired us to write this short communication on nitrogen dioxide NO2-phili...

An algorithm for computing the nonlinearity of a Boolean function from its algebraic normal form (ANF) is proposed. By generalizing the expression of the weight of a Boolean function in terms of its ANF coefficients, a formulation of the distances to linear functions is obtained. The special structure of these distances can be exploited to reduce the task of nonlinearity computation to solving ...

A method for the identification of multiple cracks based on Discrete Wavelet Transform is presented. The analysis is provided on beams made of polymeric laminate. The estimation of the crack locations is based on the evaluation of natural modal shapes of pre-cracked beams. The modal shapes were estimated experimentally using laser Doppler vibrometry. The dynamic response of multi-cracked beams ...

The aim of this paper is to present a comparison of some popular methods for online harmonic estimation. The wellknown methods Descrete Fourier Ttransform (DFT), Enhanced Phase Locked Loop (EPLL), Adaptive Notch Filter (ANF) and method based on Extended Kalman Filter (EKF) are simulated and compared. The methods are compared in critical phases, such as the fast change of harmonic amplitudes and...

The information gathered from sensors is used to determine the health of a sensor. Once a normal mode of operation is established any deviation from the normal behavior indicates a change. This change may be due to a malfunction of the sensor(s) or the system (or process). The step-up and step-down features, as well as sensor disturbances are assumed to be exponential. An RC network is used to ...

We study the normal operator to geodesic X-ray transform on functions in setting of simple asymptotically hyperbolic manifolds. construct a parametrix for 0-pseudodifferential calculus and use it show stability estimate.

We consider the limit of empirical spectral distribution Laplace matrices generalized random graphs. Applying Stieltjes transform method, we prove under general conditions that converges to free convolution semicircular law and normal law.
