Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco-elastic dampers in cable-stayed bridges is investigated by joining the center difference method and the state space strategy. Both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. The space nonlinear vibration equations of the cable-damper system are derived, and anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.

静止背景的情况通常发生在摄像机相对静止状态，首先用预处理的方法去除噪声，其次采用帧间差分统计的方法进行分析计算背景，在此基础之上利用恢复的背景及当前帧的信息检测运动目标及其运动轨迹；对于动态背景的运动图像，由于背景是不断变化且呈现出复杂的特征，因此很难准确求出静止背景，本文在光流矢量场和配准方法的基础上探讨研究了光流模型、背景模型和基于熵的方法，在动态图像上分离不同的目标与背景，直接检测出运动目标并画出相应的轨迹。针对运动图像的复杂性，本文提出了构建模型知识库的设想。

The thinking of this method as follows:Firstly,using single evaluation methods to evaluate.If the evaluation results aren\'t same,the Spearman rank correlation coefficient is used to calculate the correlation among the results of single evaluation methods.Based on the results,the traditional combined evaluation methods are used to combine the results of the single evaluation method.If the results of the upper combined methods are not same. Here the combined method evaluation indexes,such as Spearman rank correlation coefficient,correlation degree,the max deviation,average deviation,are used to evaluate the upper four combined evaluation methods.The entropy method is used to calculate the weights,and then get the final evaluation result.
