System testing in locale dock proved : the system could do moving vessels detecting , abnormal events registering and video abstraction and filtering effectively , which improved quality and efficiency of dock inspecting and could be applied to dock control without man 经现场测试,能有效地监测运动船只、记录异常事件以及视频图像的提取和过滤,提高了码头监管的质量和效率,可广泛应用于码头无人监控。
In this paper , two design methods are proposed to analyze the alternative defensive ability of structures according to the characteristics of abnormal events ; designing of the alternative defensive ability are graded according to the importance and functional requirement of buildings 结合偶然事件的发生特点,介绍了结构进行二次防御能力设计的两种方法,并给出了按重要性和功能要求对建筑物二次防御能力设计的三种分类。
The alternative defensive ability of structures refers to their ability to adjust the internal forces automatically to avoid the continuation of damage and maintain the whole structure stability when local members failed unexpectedly due to abnormal events or severe local overloading 摘要结构的二次防御能力是指结构因突发事件或局部严重超载而造成部分构件突然失效时,结构自行调整内力、阻止破坏过程的延续、保证结构不发生整体破坏的能力。
A codebook - based event correlation approach is introduced . by considering detection and identification of abnormal events as coding problems , fault localization can be done efficiently and noises in event streams can be detected . at present , demands for fault management automation are very wide 本文引入代码书( codebook )技术实现事件关联,其基本思想是将检测和标识系统中的异常事件看作编码问题,具有运行速度快、能自动识别事件流中的噪音等优点。
