With the emergence of high-bitrate applications, cross stratum optimization (CSO) attracts the interest of network operators because of its application in the joint optimization of optical networks and application stratum resources. Given the large-scale growth and high complexity of optical networks, achieving a more effective, accurate, and practical CSO becomes an important research focus. In this letter, we present a CSO-oriented, unified control architecture for OpenFlow-enabled triple-M optical networks. A novel dynamic global load balancing (DGLB) strategy with dynamic resource rating for CSO is presented based on the proposed architecture. The DGLB strategy is then compared with four other strategies by conducting experiments on a SOFT-based testbed with 1000 virtual nodes.

数字图像相关(DIC)方法是一种重要的位移和应变非接触式测量方法。为了对物体的非均匀应变进行准确测量,在DIC方法中引入位移最小一乘拟合,鉴于最小一乘拟合解析方法求解困难,采用基于模拟退火的混合粒子群算法进行求解。开展了虚拟剪切带形成的数值实验和相似材料断层滑移实验,并对非均匀变形条件下最小一乘拟合和最小二乘拟合的应变测量结果进行对比。研究发现:对于非均匀应变测量,最小一乘拟合的结果要优于最小二乘
针对坐落于意大利帕维亚大学的TRIGA Mark II反应堆热柱结构进行优化设计, 从而满足面向硼中子俘获治疗(BNCT)的单光子发射计算机断层成像(SPECT)研究要求。为提高计算效率并减小统计误差, 对比分析使用SSW/SSR方法与直接使用反应堆为源项时热柱内照射位置处中子能谱, 其结果基本一致, 从而验证了SSW/SSR方法的可靠性。为在该反应堆开展BNCT中SPECT实验, 热柱中子束需准直为笔形束。对比分析四种热柱优化方案下束流口处及探测器处热中子和光子通量: 40 cm长石墨(射束口5 cm×
输出十万瓦的近紫外脉冲气体激光器已在美帝阿夫科·爱伐列特研究所研制出，取名为“C102型”。脉冲重复频率为每秒一百次。与迄今为止的固体激光器比较，其显著的特征是总滞后时间在1微秒以内，并能不断保持等待触发信号的状态。
提出了一种基于压缩感知(CS)和干涉原理的双灰度图像加密方法。该方法分别从两幅灰度图像中随机提取50%的数据，并将这些数据通过融合形成一幅合成图像(SI)。再将该合成图像加密至三个纯相位板(POMs)中。其中一个随机相位板使用随机函数生成，另外两个通过解析的方法得到。解密时，利用分束片对3 个POMs 的衍射场进行叠加，在光学解密装置中利用CCD 记录合成图像，再从合成图像中分别提取的两幅原始图像信息。尽管对于每一幅原始图像来说，只能准确提取其50%的数据，但是压缩感知重构算法可以高质量的重现这两幅原始图
