简介：作文向量树(CVTrees)被一个没有排列、没有参数的方法从整个染色体的数据推断。有相应分类的这些树的协议在这个工作提供推断的发展史的一个客观理由，我们证明由表现的CVTrees的稳定性和自我一致性自举并且大折刀重新采样测试适应了这条没有排列的途径。我们的最终的目标是倡导费时间的统计重新采样测试根本能在使用这条没有排列的途径被避免的观点。对分类的同意应该作为一个主要标准被拿估计原核生物的种系发生的树。

简介：反公羊保护桩系统，在大楼和基础结构附近被安装，能阻止非法的车辆进入，从忍受车辆的即席创作的爆破装置(VBIED)维持距离并且减少相应损坏。与一个固定保护桩系统相比，当当需要时，它能被移开，一个可移动的保护桩系统提供更多的灵活性。这份报纸首先建议评估K4的可移动的反公羊保护桩系统的一种新类型。模仿撞击保护桩系统的车辆的碰撞，一个有限元素模型然后通过数字模拟结果和存在试验性的结果的比较被造并且验证。基于直角的设计方法，影响这个建议系统的安全和经济的因素根据他们的重要性被检验并且排序。一个最佳的设计计划然后被生产。最后，策划验证建议设计的有效性，包括影响测试的二前面影响测试和二个方面，四动态影响测试根据BSI说明被进行了。标本的剩余旋转角度比30o小并且满足BSI说明的要求。
