This paper use Mirror closed extension to solve the problem of end effect. Mirror closed extension maps the signal into a periodic signal of the ring through the mirror image method, and there is no endpoint, and fundamentally avoids the end effects of EMD and Hilbert transform.

针对这一。。。更多问题，本文利用镜像闭合端点延拓来抑制端点效应，闭合端点延拓法即用镜像法把镜内信号映射成一个周期性的环行信号，不存在端点，从根本上避免了EMD和Hilbert变换的端点效应。

The possibility to transform it into a closed set of coupled differential equations of motion is made to facilitate the numerical efficiency.

我们还对长期争论的问题，例如细致平衡原理和热库重整能量以及所对应的耗散动力学近似本质，进行了定性和定量分析，从而得到了明确的结论。

They understood how he would be able to transform it into something sublime, while another actor might reduce it to a cloying parable.

他们知道他不会像其他人一样把这个片子简单地表现为一个寓言故事，他拥有将该片演绎得更为丰富精彩的能力。

Jewelry is really the easiest way to transform from day to evening,' she says, noting that she carries a little studded or jeweled clutch in her daytime bag when she has evening events to attend.

加西亚女士说，珠宝首饰真的是将日装变成晚装的最简单的方法。她说，每当有晚间活动需要出席的时候，她总是会在白天的手袋里装上一只饰有金属或珠宝的晚装包。

It s found that wavelet transform is similar to the frequency response of cochlea, since both of them are proportional bandwidth filters.

经分析发现，小波变换是对人耳蜗频率响应的近似，二者都是一组比例带宽滤波器。

In addition, the hardware architecture of a fast codeword search algorithm based on Hadamard transform has also been proposed.

此外，本文还提出了基于哈德玛变换快速码字搜索算法的硬件结构。

This paper studies information hiding in audio signal by quantifying the amplitude of the transform domain coefficient and does some amelioration for the system communicated in analog circumstance.

本文主要讨论一种基于系数量化的音频信息隐藏算法，并针对模拟信道传输的通信系统特点对其作了一些改进。

According to the process of MFCC calculation in raw audio, a new Mel-Frequency Cepstral Coefficients algorithm by utilizing Modified Discrete Cosine Transform coefficient in MP3 domain was presented.

根据非压缩域中MFCC的求取过程，提出了一种在压缩域MP3格式下利用MDCT系数计算MFCC特征参数的新方法。

The algorithm performs discrete cosine transform on sub image of host image, which is cover by visible watermarking, and compresses sub image by select the set of visually important DCT coefficients. Then, the algorithm hides the compressed sub image, which is encrypted by the hash function that is constructed by Rijndael code, in the high coefficient of wavelet domain.

算法将水印图像与宿主图像进行融合，并对隐藏子图采用DCT变换，按Zig_Zag排序保留视觉重要DCT系数的方法作压缩处理，并利用Rijndael密码构造单向Hash函数作加密处理，最终分散嵌入到宿主图像的带参数的整数小波域中的高频系数，实现了可见水印的有效嵌入。
