Abstract This paper proposes a simulation algorithm of transition probability function based on logistic distribution. method mainly models popularity and state functions by acquiring consumers' music preferences likes. Through this mathematical model, obtains the best results that are more in line with consumer preference. conducts experiment collecting Netease cloud data. Finally, through com...

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...
