简介：在氧化的缺氧的硫化物(ASO)的最佳的操作条件生物反应器被调查。最大的移动为硫化物评价；硝酸盐被发现是4.18kg/(m[3]·d)；1.73kg/(m[3]·d)分别地。装载在固定底层集中整个减少的水力的保留时间(HRT)观察的率(LR)的volumetricalvolumetri比由在固定HRT增加底层集中的那些高。在ASO反应堆的硫化物氧化部分正在生产两硫酸盐；硫；但是生产的硫酸盐的数量是约三分之一硫的。这个过程能高容忍硫化物集中，当流入的集中直到580mg/L时，硫化物移动百分比总是在99%附近留下了。它容忍了因为当流入的集中在110mg/L上面被增加时，移动百分比落下到85%，相对降低硝酸盐集中。这个过程能容忍更短的HRT但是小心的操作被需要。自从当HRT从3.12h被减少到2.88h时，进程性能突然地败坏了，硝酸盐变换比硫化物变换对HRT更敏感。以便在反应堆避免亚硝酸根累积，流入的硫化物；硝酸盐集中应该在280mg/L被保留；67.5mg/L分别地。现在的生物工学为把硫化物从下水道移开是有用的；原油。

简介：静态、运动学的testings被使用IGS5min，30年代和5s间隔调查在精确的点放的精确卫星钟产品(PPP)答案。测试结果证明IGS卫星钟的采样率在静态的PPP答案上有很小的效果。精确卫星钟的采样间隔的所有三种类型能满足放精确性的公里厘米水平；更高的采样率没为PPP答案有重要改进。然而，卫星钟的采样率在运动学的PPP在PPP答案上有重要影响。越高卫星钟的间隔，精确性完成了越多更好。运动学的PPP的精确性完成了由用30s间隔，精确卫星钟被使用精确卫星钟和30s间隔卫星钟能几乎生产的5min间隔被将近3050%关于答案改进运动学的答案的一样的精确性。而且，从不同分析中心的精确卫星钟产品的使用可以也差不多在PPP答案上生产效果。

简介：这篇文章在直角的频率部门multiplexing(OFDM)与min率要求限制处理multicast资源分配问题系统。由于为非线性、组合的优化的禁止地高的复杂性，原来的问题被放松并且形成一个标准优化问题的reformulated。根据Karush-Kuhn-Tucker(KKT)由理论推导调节，二项提议为optimality表现为必要标准。而且，包括副载波赋值和力量分配，一个二拍子的圆舞资源分配计划在实际实现的提议的一个基础上被建议。多点传送，min率基于组顺序，副载波以一种贪婪方式被分配最大化能力。当副载波赋值是坚定的时，建议力量分配能完成最佳的性能因为min率与可接受的复杂性抑制了能力最大化。模拟结果显示建议计划接近到彻底的搜索与可以忽略的能力差距获得的最佳的资源分配，并且更加超过相等的力量分发。同时，多点传送对在OFDM系统的资源利用显著地有益。
