Abundance and distribution of Trichodesmium in the continental shelf waters of the South China Sea

束毛藻（Trichodesmium）属于群体海洋固氮蓝细菌，主要分布于贫营养的亚热带和热带大洋，被认为是贫营养海区“新”氮的重要来源。它在我国近海（包括渤海、黄海、东海和南海）和沿岸水域都有一定数量的分布，甚至多次形成赤潮。当前对“陆架泵”（大气CO2吸收机制）研究的关注，大大增强了陆架区水域束毛藻的丰度、分布及固氮速率研究的重要性。 本文首次报道了南海陆架区（包括南海北部陆架区和北部湾东侧海域）束毛藻的丰度、水平和垂直分布模式，探讨了陆架区水域束毛藻丰度与分布的调控因子，旨在为陆架区以至中国海的束毛藻的生物量及其对固氮贡献的估算等提供参考依据。 主要成果如下： 1. 南海陆架区，束毛藻...Trichodesmium, a colonial marine cyanobacterium, is primarily distributed in oligotrophic tropical and subtropical oceans.

基于随机森林的建筑结构损伤识别方法

针对利用分类器对建筑结构进行损伤识别的问题,引入一种新的组合分类器算法——随机森林,提出基于小波包分解和随机森林的结构损伤识别方法。首先,采用小波包对结构在不同损伤程度和位置上的振动加速度信号进行分解,得到各个频带上的总能量;然后,利用各频带上能量值存在着差异性作为输入到分类器的特征向量;最后,训练随机森林模型并对建筑结构的损伤位置和损伤程度进行识别。应用该方法对一座8层剪切型钢框架结构进行损伤判别,并与BP神经网络和支持向量机方法进行对比,结果表明该方法具有较好的识别精度与稳定性

Characters Segmentation of License Plate Based on Combination of Projection and Intrinsic Characteristics

根据车牌字符的固有特征,提出一种新的基于投影的车牌字符分割方法。该方法首先对车牌图像进行预处理,检测车牌倾斜角度,如果倾斜角大于指定角度则进行车牌倾斜校正,然后利用车牌的水平方向投影去除车牌的上下边框以及铆钉,对处理得到的图像进行二值化。再根据车牌字符的排列规则和字符间距的关系,利用车牌的垂直投影定位字符,先分割出第二个和第三个字符,从第三个字符开始分割出后五个字符,再利用已分割字符的知识来分割前两个字符,然后对分割出来的候选字符块进行处理,有效解决字符粘连和断裂的情况,最终实现车牌字符的准确分割。实验结果证明,该方法有较好的分割效果。According to the intrinsic characteristics of license plate,a new approach for characters segmentation of license plate based on projection is proposed.Firstly,some preprocesses are processed toward the license plate images-detect the incline angle of license plate and rectify the slanted and distorted plate if the incline angle is bigger than the designated angle,then the horizontal boundaries are removed by using horizontal projection of license plate.After these processes,image binarization is processed to the image.Then the characters are located by using vertical projection of license plate,according to the ranging rulers and intercharacter distance of license plate characters.The second and third character are first segmented,then the last five characters from the third character are also segmented.With the knowledge of single character which has been segmented,the first two characters are segmented.Then all the possible characters are processed specially,segmenting the conglutinant characters and combining the cracked characters if existing.As a result,all the characters are segmented accurately.The experimental result shows that this approach has a good effect of segmentation.国家自然科学基金(40627001
