简介：在这份报纸，活跃光学和合作焦点，分割的镜子的试验性的系统被造。第一，分割的镜子的支持结构被设计，为分割的镜子的试验性的系统满足要求被模拟验证。在这个系统，大散焦并且倾斜/付小费给分割的镜子的错误被观察密度调整并且基于等斜的干扰理论干扰穗形成对照直到defocus并且倾斜/付小费给错误在Shack-Hartmann的侦探范围。然后，Shack-Hartmann被用来测量他们，他们被致动器调整。致动器被活跃光学控制为分割的镜子的好合作焦点认识到靠近环的调整和维护。并且干扰穗被利用验证Shack-Hartmann的侦探精确。在分割的镜子调整的合作焦点以后，倾斜/付小费给剩余表面错误比RMS好；defocus剩余表面错误比RMS好。

简介：客观：为了学习肺，损害由分割的冲击波引起了。方法：60只兔子和20只老鼠的一个总数在这研究被使用。冲击波的传播的过程被划分成三个阶段，即，压缩阶段(RP)，解压缩阶段(DP)并且在压力阶段下面(起来)。并且压缩飘动(RW)，解压缩波浪(DW)nd分别地，在模仿的压力波浪(UW)下面，三个阶段由我们设计的设备产生了。RW测试，DW测试和UW测试分别地被用于动物。并且分割的冲击波引起的肺损害被讨论。结果：在试验性的条件下面，RW没引起明显的肺损害，但是DW能引起肺损害的不同严厉。更大解压缩变化了并且解压缩持续时间越突然被采用，越多严重肺损害被观察。到某程度，UW能引起明显的肺损害。结论：它建议在冲击波下面的肺损害可能首先发生在DP期间。它可能不在RP期间引起直接明显的肺损害，但是显著地影响在DP期间引起肺损害的能力。

简介：我们集中于爆炸汇编机制并且建议IP包的数字根据交通负担和爆炸在被改变的包被分割进几部分的爆炸从几个因特网协议(IP)在被装配的一个新聪明的方法，叫了ISOBS机制。ISOBS机制的平均爆炸集会时间作为与fixed-assembly-time和fixed-assembly-time-and-length机制相比减少。损失比率减少50%作为与切换的一般光爆炸(OBS)相比机制。最后片断能带服务(QOS)的高质量信息。我们能完成当交通负担是不到0.05时，最后片断的损失比率是几乎零。当交通负担是0.9时，最后片断的损失比率是0.0041。ISOBS能支持播送不同QOS数据。

简介：一个不规则的分割的区域编码算法基于脉搏，联合神经网络(PCNN)被介绍。PCNN有联合脉搏、可变的阀值，有近似灰色的价值的这些邻近的象素能同时通过被激活的性质。一个人能得出PCNN有的优点认识到地区性的分割，和细节的一个结论原来的图象能被分割图象的参数调整完成，并且同时，小分割的区域能被避免。为不规则的分割的区域的更好的近似，Gram-Schmidt方法，一组orthonormal基底函数被从一组线性独立的起始的底构造工作，被采用。因为重建的orthonormal方法，重构图象的质量能极大地被改进，进步图象传输将也是可能的。
