This paper presents a nonwatermarking algorithm based on the most significant bits to construct the key. Firstly, the binary watermarking image is scrambled and extended to the size of the main image.Then the value of every pixel of the watermarking image is compared with that of the corresponding MSB of the main image. When the compared value is true,the location of the main image is marked by a zero matrix, and the marked zero matrix is a key that can be used to detect the watermarking image later.

本文提出一种基于最高有效位构造密钥的零水印算法，先将二值水印图像置乱并拓展为载体图像的大小，再将其像素值与载体像素的MSB进行对应比较，当比较结果为真时，用一个零矩阵来标记载体像素的位置，被标记过的零矩阵作为密钥来检测水印。

Quadratic assignment problem is a NP-hard combinatorial optimization problem and has been applied in various fields. There are always many zero elements in the flow matrix or distance matrix of the quadratic assignment problem instances which are abstracted from the practical problems. Much computation time can be saved if we can first reduce the size of the problem by using its zero elements.

The design of output feedback H(subscript ∞) controllers is discussed for nonlinear discrete singular systems. First of all, by means of generalized Lyapunov function and linear matrix inequalities, zero solution E-asymptotically stable is studied for the system, a sufficient condition is given such that the system is zero solution E-asymptotically stable and a H(subscript ∞) norm constraint.
