代码说明：

MFCC参数和LPCC参数需要频繁使用的语音的说话人识别分析还需要使用大量的这些特征参数,这就需要研究MFCC和LPCC算法和参数提取的原则。因为我们需要了解与人交谈的过程中,我们要进行建模率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(MFCC parameters and LPCC parameters are parameters of speaker recognition which requires frequent use of voice analysis also need to use a lot of these characteristic parameters, This requires research MFCC and LPCC algorithm and the principle of parameter extraction. Because we need to understand the process of talking to people, we want to conduct a speaker modeling the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula)

IJERTV1IS7260
DC power is steady and continuous, with an electrical charge that flows in only one direction. When the output of DC power is represented on a graph, the result would be a straight line. AC power, on the other hand, flows back and forth in alternating directions so that, when represented on a graph, it appears as a sine wave, with smooth and regular peaks and valleys. A power inverter uses electronic circuits to cause the DC power flow to change directions, making it alternate like AC power. These oscillations are rough and tend to create a square waveform rather than a rounded one, so filters are required to smooth out the wave, allowing it to be used by more electronic devices.

VCSOA_Bistability_RateEquations
这是一个关于垂直腔半导体光放大器（VCSOA，微腔光放大器的一种）中的双稳态曲线计算程序，用Matlab语言写成，可执行。程序是根据VCSOA中的速率方程（Rate Equation）编写的。从曲线上可以看出随着输入功率Pin的变化VCSOA的输出功率Pout的双稳态曲线，是进一步研究该问题的基本素材之一。(This is a computation program for calculating the bistability activity of the vertical cavity semiconductor optical amplifier, which is based on the rate equation in VCSOA. This code is a basis for further investigating other activities in VCSOA related to bistability. )

T_XTIDE Tidal prediction YOUT=T_XTIDE(STATION) makes a tidal prediction for the current day using the harmonics file XTIDE. Predictions at other times can be generated using [...]=T_XTIDE(STATION,TIM) where TIM is a vector of matlab-format decimal days ( DATENUM). If TIM is a scalar then it is taken as the number of days present over which to make predictions. If TIM>1000 then it is taken to be the starting time in matlab-format. at the matlab time JD (UTC, but see code for details) where tau = lunar time s = mean longitude of the moon h = mean longitude of the sun p = mean longitude of the lunar perigee np = negative of the longitude of the mean ascending node pp = mean longitude of the perihelion (solar perigee)
