简介：作者在局部地凸的空格给稳固的锥的双描述。从这，作者为判定凸的锥在局部地凸的空格的各种各样的类型稳固获得一些标准。用一个稳固的锥的内部的一个一般表达式，作者获得很多个必要、足够的条件让凸的锥在Banach空格的框架稳固。特别地，作者给在稳固的锥和概括的锋利的锥之间的一种双关系。相关已知的结果被改进并且延长。

简介：当它极大地影响用户满足的度，申请发射性能对系统站台开发者和供应商很重要。改进应用程序发射性能的最最有效的方法是用一个稳固的州的驱动器(SSD)代替一个硬盘驱动器(HDD)，它最近变得买得起、流行。一个自然问题当时是是否用一个新SSD知道的优化器代替传统的HDD知道的申请发射台。我们由在SSD上分析HDD知道的申请发射台的无效然后建议预取计划的新SSD知道的应用探讨这个问题，叫了快申请跑步者(快)。关键想法快是重叠有SSD存取(I/O)的计算(中央处理器)时间时间在应用程序发射期间。快由一套用户级的部件和LinuxOS(操作系统)提供的系统调试工具组成。因此，没有核重新编译，能容易快在任何最近的Linux版本被部署。我们与运用Linux2.6.32OS的SSD在桌面PC上快实现并且由运行一套使用得广泛地的应用程序评估它，表明象与没有prefetcher的PC相比的申请发射时间的28%减小的一般水准。

简介：这份报纸在小粒的固体的体积回答上检验严肃的影响。在这研究的装载情形包括限制压缩，杆穿入进小粒的媒介并且通过一个孔排出。类似的装载和流动条件是可能的在表土在在situ资源利用过程包括的地球外的探索活动受到的压力和变丑政体被遇到。球形、非球形的粒子用分离元素方法(DEM)被学习。虽然DEM逐渐地被用来为小粒的固体建模，模拟结果的小心的确认是相当稀罕的。因此除了探索严肃的效果，这份报纸也在陆上的状况下面把DEM模拟与实验作比较验证DEM是否能生产令人满意的预言。陆上的实验与大照顾被进行并且用DEM仔细模仿了。为粒子的关键机械、几何的性质在DEM模拟为使用在实验室测试被测量。一系列DEM计算然后在减少的严肃下面被执行在地球外的环境下面模仿这些实验。严肃没在限制压缩盒子中在力量传播上有显著效果，这被发现；在杆穿入的装载坡度与严肃线性地成正比；在地窖分泌物的集体流动率是比例的与减少严肃摆平严肃和休息增加的角度的根。这些调查结果与期望一致并且存在科学证据。
