this paper shows how multifractal analysis can be used to characterize the spatial distribution of epicenters in the zagros and alborz-kopeh dagh regions of iran. the main multifractal characteristics, dq, f(αq), τq, αq and a set of multifractal parameters defined from the shape of the f(αq)-spectrum including the width of f(αq)-spectrum, nonuniformity factor, combined parameter, coefficients o...

The recent development of the synthetic aperture imaging radar [Brown and Porcello, 1969; Harger, 1970; Rihaczek, 1969], which generates high-resolution surface imagery from an airborne or spaceborne platform, has generated interest in the scientific community for its use as an all-time all-weather remote sensor to study the earth's solid surface, oceans, and polar regions [Bradic, 1967; Waite ...

In this paper, we present two robust feature extractors that use a regularized minimum variance distortionless response (RMVDR) spectrum estimator instead of the discrete Fourier transform-based direct spectrum estimator, used in many front-ends including the conventional MFCC, for estimating the speech power spectrum. Direct spectrum estimators, e.g., single tapered periodogram, have high vari...

The revenue management concept and techniques are applied to model the coordination of supply chain elements. The fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. The output of the supply chain can be various products and thus it is measured in terms of ...

Using the nonlinear constraint and Darboux transformation methods, the (m1, · · · ,mN ) localized solitons of the hyperbolic su(N) AKNS system are constructed. Here “hyperbolic su(N)” means that the first part of the Lax pair is Ψy = JΨx + U(x, y, t)Ψ where J is constant real diagonal and U = −U . When different solitons move in different velocities, each component Uij of the solution U has at ...

Prewhitening is often considered a necessary but not sufficient condition for stronger stochastic independence criteria. After prewhitening the task of Blind Source Separation (BSS) become somewhat easier. Robust preprocessing involves spectral whitening, which is done by transforming correlated signals to an uncorrelated flat spectrum signal. The maximum entropy power spectrum estimation has b...

An ASEP with two species of particles and different hopping rates is considered on a ring. Its integrability is proved and the Nested Algebraic Bethe Ansatz is used to derive the Bethe Equations for states with arbitrary numbers of particles of each type, generalizing the results of Derrida and Evans [10]. We present also formulas for the total velocity of particles of a given type and their li...

This paper proposes novel robust speech F0 estimation using SRH (Summation Residual Harmonics) based on TV-CAR (Time-Varying Complex AR) analysis. We have already proposed robust F0 estimation based on the TV-CAR analysis in which weighted auto-correlation for complex residual signals is used as the criterion. In the SRH method, the criterion is calculated from LP residual signals. The criterio...
