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：吸收材料(静态存储器)的一架新奇结构的雷达，给正常树脂底composites新功能，被准备。静态存储器的动态压缩测试借助于裂口Hopkinson压力酒吧(SHPB)在在里面飞机和composites的正常方向被执行。在沿着在里面飞机方向的压缩测试，失败发生在在纤维和矩阵之间的接口。一个破裂模式和机制被建议解释这些结果。吸收粒子的增加导致压缩性质的恶化。然而，有吸收性质的雷达的静态存储器的压缩力量上没有明显的减少。

简介：到萤火虫的调节颜色的机制的明确的水分子的贡献被学习。明确的水分子在keto的几何参数引起二不同结构(在vacuo和水的答案的-1)。吸收和排放系列上有有点更大的影响。当水分子仅仅在benzothiazole戒指的方面上被增加时，系列变到蓝色。相反，当水仅仅在thiazoline戒指的方面上被增加时，系列变到红。简言之，射出的光的颜色调整取决于分子keto的费用再分配(主要，benzothiazole和thiazole的费用变化在keto在二个终端包围的-1),(-1)。

简介：我们与边weighting机制建议一个新奇雪堆比赛模型在方形的格子上在运动员之中探索合作行为。包括制服基于重量分发的三种类型的假设，指数并且幂定律计划，合作水平大部分在未加权的方形的格子上与传统的雪堆比赛在对比被增加。广泛的数字模拟显示合作者的部分极大地扩充，特别为cost-to-benefit比率r的中间的范围。而且，我们调查合作行为怎么被重量分发的波动振幅和策略选择的噪音力量分别地影响。模拟结果将是导致的推进理解并且分析合作的出现，它是在社会、生物的科学的无所不在的现象。
