In every period, do the following operations:# For each 8*8 block, do the discrete cosine transform, then take out direct current coefficient in each block, using the transformation above for each DC coefficient, the gold stands for the code of the spread-spectrum we use when embedding the different watermark bit in different frames, after all of the watermark information which we want to embed is embedded, then do the inverse discrete cosine transformation, and store the current frame in a new file.
于是利用DCT变换域的这点重要的几何不变性,我们可以推导出一种能够抵抗几何攻击的视频水印算法,即将所需要嵌入的水印信息以127位扩频序列作为辅助,以求和值形式嵌入到DCT变换后的每个宏块的每个DC系数当中,具体嵌入和提取算法如下:根据使用的扩频序列的长度N,基于相关的嵌入器需要选取包含N帧的视频子序列,令这N帧视频子序列作为一个嵌入周期,对于每N帧视频子序列做如下的操作,#即对于每个8×8的像素块进行DCT变换,然后取出每个DCT变换后的直流分量,对于每个DC系数,做如上所述的变换,其中gold为在第k帧中嵌入第i位水印信息时使用的扩频码字值,待将所有需要嵌入的水印信息全部嵌入后,再做反DCT变换,保存当前帧。

A selective and mild PS-DIB/ionic-liquid immobilized 2, 2, 6, 6-tetramethyl-piperidin-4-ol-N-oxyl catalytic oxidation procedure of alcohols to the corresponding aldehydes and ketones in ionic liquid BF4 at room temperature was developed. The oxidant PS-DIB was prepared via the iodation and acetylation of polystyrene resin. For the preparation of the ionic-liquid immobilized TeMPO catalyst, 4-(2, 2, 6, 6-Tetramethyl-1-oxyl-4-piperidoxyl)butyl bromide was first synthesized from TeMPO and 1, 4-dibromobutane.

Adopting generalized Jordan block and algebra equivalence transform method, all of the transfer functions at different load points can be transformed to state-space description with time variable. The steady robustness of three different mode of control systems were researched by mathematic analysis. It shows that: for the high order inertia controlled object with the characteristic of nonlinear and time-variable that described by the set of transfer functions, the Luenberger function observer established according to its any algebra equivalence state-space description, if some conditions can be met, there would be a matrix of T with n′n satisfied the Sylvester matrix equation TA- FT=GC.
