One of the new methods that used in Voice activity detection (VAD) systems is estimating the Probability Distribution Function (PDF) of the speech signal. This estimation becomes hard in noisy environments especially low value of Signal-to-Noise Ratios (SNR). This paper studies on three types of PDFs and selects one of them to modify and approximate the original signal. Then we compare the resu...

[1] The probability distribution function (PDF) of the upper (0–50 m) tropical Pacific current speeds (w), constructed from hourly ADCP data (1990–2007) at six stations for the Tropical Atmosphere Ocean project, satisfies the twoparameter Weibull distribution reasonably well with different characteristics between El Nino and La Nina events: In the western Pacific, the PDF of w has a larger peak...

Bond vector probability distribution function of bulk molecules. Abstract: In our previous work we studied dynamics of the interfacial layer between flowing polymer melt and a solid wall. We showed that the ensemble-averaged behavior of the polymer molecules grafted on the wall could be successfully described in terms of the so-called bond vector probability distribution function (BVPDF). As wa...

The probability density function (PDF) of the surface electromyogram (EMG) signals has been modelled with Gaussian and Laplacian distribution functions. However, a general consensus upon the PDF of the EMG signals is yet to be reached, because not only are there several biological factors that can influence this distribution function, but also different analysis techniques can lead to contradic...

The aim of this study is to investigate how the weibull distribution function compatible with wind data in offshore regions. Especially increase energy demand and advancement technology, importance has increased. Many academic studies on have been conducted are being at same time. Determination potential making investments area accelerated today. Although many made field energy, it not sufficie...

We present an approximate form for the weak lensing magnification distribution of standard candles, valid for all cosmological models, with arbitrary matter distributions, over all redshifts. Our results are based on a universal probability distribution function (UPDF), P (η), for the reduced convergence, η. For a given cosmological model, the magnification probability distribution, P (μ), at r...
