It researches the two linked structure that the heights are more different of using damper linked and control the earthquake responding,and discusses the affection of different damped coefficient and earthquake wave to damping through comparing the earthquake responding of structure.
对高度相差比较大的两相连结构利用阻尼器连接控制地震响应方面进行了研究,通过比较结构的地震响应,探讨了不同阻尼系数和不同地震波对减震效果的影响。
For the automatic target detection in infrared image sequences,a new infrared target detection algorithm based on morphological filtering and joint relative entropy is proposed.
提出了一种基于多尺度形态学和连接相对熵的红外图像自动目标检测方法;它首先对目标红外图像进行多尺度形态滤波,消除背景和杂波的影响同时增强目标的对比度,然后采用连接相对熵准则确定区分目标和背景的最佳门限,最后对得到的二值图再进行形态滤波,得到精确的目标分割图像。
