代码说明：

说明： Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum data shows stable for watermark hiding by the methods of edging data cutting and statistical mean modification. The synchronization is not required in the algorithm. Experimental results show that the proposed algorithm can resist on the attack of A/D and D/A successfully with features of large capacity and zero bit error. It will be helpful for the mobile audio in secure broadcast and management in the

当前，矢量控制是一种优越的交流电机控制方式，它模拟直流电机的控制方式使得交流电机也能取得与直流电机相媲美的控制效果。依据矢量控制的基本原理和方法，用 456752 8 9:4 7:<= 模块构建了一个基于转子磁场定向的旋转坐标系下的交流异步电机矢量控制系统仿真模型，对其速度控制器提出并设计一种模糊滑模变结构控制算法。该控制算法具备模糊逻辑控制和滑模变结构控制两者优点，并且较好地解决了滑动模态的抖动问题。仿真结果表明了该设计的可行性以及具有良好的动静态性能、较强的鲁棒性(6.C+D& EFB@.A B.*@A.G !

站长，不好意思... 我将我的信箱写错了... 写成：ddccbbaa@sina.cn了... 前面我传输的文件是：“qibaoshanplan.doc”这个文件，并且，是我的一篇论文底稿，我还想您提出了建议“增加创意文案的文件上载”的类型。我的名字叫：褚江。这篇文建，我又重新上传了一下... 我会为我的错误买单，马上我再传一篇论文，是我在《云计算》的课堂上书写的... 希望站长，能够将弟我，重新添加到PUDN的大家庭中。(Master, I am sorry ... I was wrong ... in my mailbox written: ddccbbaa@sina.cn up ... in front of my files transferred are: " qibaoshanplan.doc" the file, and it is my a thesis papers, I would like your recommendations " to increase creative copy of the file upload" type. My name is: Chu River. This CCA, I re-uploaded it ... I' ll pay for my mistake, I immediately re-transmission of a thesis, I was in the " cloud computing" classroom writing ... hope that the station can be The brother I re-added to PUDN the family.)
