简介：这份报纸涉及为在逆的某未知分布式的流动的数字重建的一个有限元素方法的估计加热的一个priori错误传导问题。更精确，一些未知分布式的Neumann数据将在外部可存取的边界上用Dirichlet测量数据在内部无法接近的边界上被恢复。在这个工作的主要贡献是建立分别地，一个priori错误在领域并且在可存取/无法接近的边界上以网孔尺寸估计的一些因为温度u和伴随在最低整齐假设下面说p。集中率的更低的界限取决于领域的几何学，这被揭示。这些估计自己具有巨大的兴趣并且铺的一个priori错误为证明集中是适应技术的分析的方法把反的热传导问题的班用于一个将军。数字实验被介绍验证我们的理论预言。[从作者抽象]

简介：从Baiyangdian异构的田间试验收集的热流动数据用脚印方法被分析。高分辨率(25m)Landsat-5卫星成像被用来作为四种表面类型之一决定土地覆盖：农田，湖，沼泽地，或村庄。从在2005年9月的二个观察地点的数据被使用。一个地点(Wangjiazhai)被高度异构的表面在Baiyangdian的中央区域描绘：湖/沼泽地。另外的地点(Xiongxian)在有更多的一致表面盖子的土地上。一个改进Eulerian分析流动脚印模型被用来决定“在从包围混合表面类型的风景在每个地点定位的塔测量的热流动的来源区域”。在相对术语，结果证明沼泽地和湖区域通常在Wangjiazhai最作出贡献到观察的热流动，当农田在Xiongxian贡献了大多数时。给表面类型贡献的真实分布，计算被做从湖，沼泽地和农田获得热流动的大小到观察流动和每表面的分配贡献打到理智、潜伏的热流动的总数。结果平均显示出那从沼泽地和农田的可感热流动是可比较的在上日报周期，当从农田的潜伏的热流动在白天期间由大约3050Wm−2是有点更大的时。分别地，从在白天的湖来源的潜伏、理智的流动比从沼泽地和农田少些是大约50Wm−2和100Wm−2。结果被判定合理并且服务在异构的表面上为流动分配表明潜力。

简介：背景概念噪点的名字有很多,也叫噪声或噪音,主要是指感光材料(CCD或CMOS)将光线作为接收信号接收并输出的过程中所产生图像的粗糙部分,也指图像中不该出现的外来像素。噪点通常由电子干扰产生,这样的点一般情况下是随机产生的,也是没有办法避免和消除的。
