简介：为测量处理方法的一幅图象即时二维(2D)在高水泡数字密度的本地空部分被建议。它基于计算在水泡羽毛图象和真实空部分的局部地平均的亮度之间的关联。方法从设想的图象用本地空部分的2D分发被测试，在在局部地平均的亮度和设计虚空部分之间的关联被在各种各样的条件下面介绍水泡图象的重叠概率的理想导出的地方。这研究被用来与方面比率of1.0学习冒泡的流动的行为1.5，和2.0。现在的方法被用于即时测量。为有产生流动率的三个不同水泡的三不同方面比率的水泡羽毛的空部分在冒泡的流动的行为上为水泡的效果的澄清被测量。煤气的流动率上的空部分的相关性被测量并且与其它相比源于文学。在我们的实验的范围，坦克的方面比率不仅影响羽毛的结构，而且在坦克的煤气的流动率影响羽毛的结构，这被观察。

简介：高分辨率的超图象(HHR)提供详细说明的两个为城市的学习的结构、光谱的信息。然而，由于固有的关联在之间光谱在数据的乐队和在内班可变性，HHR处理的数据是一个挑战性的工作。在这糊，基于光谱混合分析理论，部分描述特征的新栈与形态学的栈被提取，然后合并基于的空间特征。部分监督的抑制精力最小化(CEM)和无指导的nonnegative矩阵因式分解(NMF)被用来提取部分特征。联合特征当时由SVM分类器是综合的。这个方法的优点是由部分特征和由形态学侧面的多尺度的结构信息的表演的城市的区域的物理作文的表示。有在华盛顿特区广场上的在空中的超数据flightline的实验被执行，并且建议算法的性能与著名nonparametric比较被评估加权的特征抽取(NWFE)和特征选择方法。显示出的结果建议特征关节计划一致地超过传统的方法，并且能那么为在城市的区域处理HHR数据提供一种有效选择。

简介：瞄准：与颜色在病人在肝切除术期间发现秘密转移表面的癌症肝转移(CRCLM)，提高对比的intraoperativeultrasonography(CE-IOUS)用一个新微水泡代理人被执行，sonazoid，它在Kupffer房间基于它的累积提供一幅实质特定的对比图象。方法：有CRCLM的八个病人在肝切除术前用sonazoid经历了CE-IOUS。肝在迟了的Kupffer阶段成像期间被调查，它是sonazoid的一个珍贵特征。结果：用sonazoid的CE-IOUS提供了早脉管阶段并且为10min的正弦曲线阶段图象在sonazoid的注射以后由迟了的Kupffer阶段图象列在后面直到30min。IOUS没在8个病人提供变形损害的新调查结果。在sonazoid的迟了的Kupffer阶段图象期间，然而，变形损害最新在8个病人中的二个被发现。这些最新检测的损害被作为转移诊断的另外的肝切除术和组织病理学说的联盟者移开。结论：用sonazoid的CE-IOUS能允许外科医生与足够的时间调查整个肝并且intraoperatively发现新转移。

简介：摘要：《驴得水》是一部由周申、刘露共同执导的荒诞喜剧电影。本片讲述中华民国时期一所农村小学，校长为了钱带头把一头小毛驴虚报成英语老师，冒领工资从而引发的荒诞喜剧故事。本片中的三个女性：张一曼、孙佳、铜匠的老婆各代表了那个时期不同的语言符号。本文将立足女性主义角度，对这三位“非弱即暴”女性形象来进行阐述。
