这个是一个好好用的完美挂请大家用用好不好用大家说说(PostScript(R) Printer Description (a.k.a. PPD) files are text files containing information about special features available on PostScript printers such as paper sizes, screen values and fonts available on your printer. These files are in a very specific format that can be read by software applications. The information is used when printing your document by the printer driver for decision making purposes or to invoke particular features of the printer. )

HOW_TO_REVIEW_A_PAPER
A fractional Fourier transform (FrFT) based estimation
method is introduced in this paper to analyze the
long range dependence (LRD) in time series. The degree of
LRD can be characterized by the Hurst parameter. The FrFTbased
estimation of Hurst parameter proposed in this paper
can be implemented efficiently allowing very large data set.
We used fractional Gaussian noises (FGN) which typically
possesses long-range dependence with known Hurst parameters
to test the accuracy of the proposed Hurst parameter
estimator. For justifying the advantage of the proposed
estimator, some other existing Hurst parameter estimation
methods, such as wavelet-based method and a global estimator
based on dispersional analysis, are compared. The proposed
estimator can process the very long experimental time

时频分析中的cohen类中最基本的双线性时频分布式wigner-ville分布，由于在该分布中不含窗函数，因此避免了短时窗傅里叶变换时间分辨率、频率分辨率相互牵制的矛盾(Time-frequency analysis of the Cohen class of bilinear time-frequency distribution is the most basic Wigner-Ville distribution, because the function in the distribution is not included in the window, so as to avoid the contradiction of short-time window Fourier transform time resolution, frequency resolution of each other)
