Surface-consistent deconvolution is a standard processing technique in land data to uniformize the wavelet across all sources and receivers. The required wavelet estimation step is generally done in the homomorphic domain since this is a convenient way to separate the phase and the amplitude spectrum in a linear fashion. Unfortunately all surface-consistent deconvolutions make a minimum-phase a...

State of the art objective measures for quantifying voice quality mostly consider estimation of features extracted from the magnitude spectrum. Assuming that speech is obtained by exciting a minimum-phase (vocal tract filter) and a maximum-phase component (glottal source), the amplitude spectrum cannot capture the maximum phase characteristics. Since voice quality is connected to the glottal so...

It is argued that an irregularity in the baryon stopping is a natural consequence of onset of deconfinement occurring in the compression stage of a nuclear collision. It is an effect of the softest point inherent in an equation of state (EoS) with a deconfinement transition. In order to illustrate this effect, calculations within the three-fluid model were performed with three different EoS’s: ...

The most commonly used deconvolution (Decon) method is based on minimum-phase assumption for the wavelet which is often not valid. Explosive energy source is close to minimum-phase which makes seismic data with explosive somewhat amenable to predictive Decon though the result is imperfect in phase. Decon of Vibroseis data is more problematic because the wavelet in a correlated Vibroseis trace i...

This paper introduces a new speech model, termed as the mixed-phase model, based on the assumption that the speech signal is produced by convolution of a maximum phase glottal excitation signal with a minimum phase vocal tract filter impulse response. The glottal excitation signal is assumed to be an anti-causal stable signal and the vocal tract filter is assumed to be causal and stable. For es...

Conventional dual-frequency fringe projection algorithm often suffers from phase unwrapping failure when the frequency ratio between the high frequency and the low one is too large. Zhang et.al. proposed an enhanced two-frequency phase-shifting method to use geometric constraints of digital fringe projection(DFP) to reduce the noise impact due to the large frequency ratio. However, this method ...

We include p-spin interactions in a spherical version of a soluble mean-field spinglass model proposed by van Hemmen. Due to the simplicity of the solutions, which do not require the use of the replica trick, we are able to carry out a detailed investigation of a number of special situations. For p ≥ 3, there appear first-order transitions between the paramagnetic and the ordered phases. In the...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
