简介：框架率相应于时间的分辨率，图画的象素的数字相应于空间分辨率。他们为研究人员两个都是很重要的。理想的图象分析和处理系统应该有高空间与时间的特征，它在实际使用是昂贵的。用多数字的照相机(DC)提高动态框架率的一个新方法被建议，结果证明它能有效地增加框架率并且减少在实际使用的费用。

简介：钢的地震行为增强了高力量，高效水泥(SRHC)框架列通过16框架列的伪静电干扰实验被调查与各种各样砍跨度比率，轴的压缩比率，具体力量，钢比率和马镫比率。三种失败机制被介绍，有不同设计参数的试验性的hysteretic曲线和骨骼曲线的特征被讨论。列韧性和精力驱散是基于地震抵抗评估的份量上。研究结果显示SRHC框架列能承受韧性的极端适用的能力，而是能力，因为SRHC自然易碎物，精力驱散是劣等的。作为结果，轴的负担比率应该被限制，一些构造措施采用了，例如增加马镫比率。这研究在SPHC列的适用的能力上建立了效果因素。最后，为用曲折失败模式获得最终的适用的能力的一个算法基于一个修改飞机节假设被建立。作者也证实决定砍的baroclinic失败并且砍的方程结合失败基于轴的负担力量分发比率的累积。计算结果砍忍受能力因为不同失败模式在对试验性的结果的好同意。

简介：作为X光检查，计算断层摄影术(CT)广泛地在诊断和放射疗法被用作，减少象一样低的放射剂量是重要的相当可完成。为这个目的，一个人可以使用基于的TV方法或小浪框架基于方法重建从设计的减少的数字的高质量的图象。由使用仅仅照亮region-of-interest(ROI)的内部断层摄影术计划，而且，一个人能节省更多的放射剂量。在这份报纸，柔韧的小浪框架规则化基于模型为全球重建和内部断层摄影术被建议。模型能帮助减少巨大的稀少的设计矩阵的失配引起的错误。一个三系统的分解计划被使用把重建的图象分解成三不同部分：动画片，人工制品和噪音。由丢弃估计的人工制品和噪音部分，因此，重建的图象能与更少的噪音和人工制品被获得。类似于基于的图象恢复建模的另外的框架，模型能被裂口Bregman算法高效地解决。数字模拟证明建议模型以锋利的边，吝啬的结构的类似(SSIM)，contrast-to-noise比率，相对错误和关联的保藏超过FBP和SART+TV方法。为真实绵羊肺重建，当FBP和SART+TV方法需要超过200设计时，例如，建议方法能到达用仅仅100设计象0.75一样高的吝啬的结构的类似。另外，建议柔韧的方法为有与FBP和SART+TV方法相比的更好的性能的内部、外面的断层摄影术是适用的。

简介：把三维的摇晃表格测试基于six-degree-of-freedom，再循环的总数水泥的地震反应(皇家装甲兵)框架被获得。分析结果显示最大的故事砍力量和翻的时刻还原剂按比例沿着在一样的地震下面的模型的高度飘动。这个故事砍力量，底砍当加速振幅增加，系数和结构的翻的时刻日益增多地增加。底砍系数被山峰地面加速(针网阵列)首先控制。在PGA和shear系数之间以及在PGA和动态扩大因素之间的关系被数学适合获得。动态扩大因素在有弹性塑料的阶段很快减少，但是与有弹性粘性的阶段的发展慢慢地减少。当与自然总数水泥相比框架组织时，结果证明RAC框架结构有合理deformability。分别地，在8测试分阶段执行的经常、稀罕的紧张下面的RAC框架模型的最大的内部故事的飘移比率是1/266和1/29它根据中国地震设计要求比1/500和1/50的许可的价值大。不过，RAC框架结构不从0.066g与针网阵列在基础刺激下面崩溃直到1.170g。
