ARBPMTAS:Attributes Reduction Based on Parameters Module in Tuning Application Server
, 2010 现实的优化方法与策略往往是优化人员基于服务器厂商所提供的官方技术文档来分析各种参数的实际意义,优化比较漫长,缺少系统性和规律性,很难快速的确定所需调节的关键参数.本文针对常用的应用服务器分析了其性能下降的原因,提出了调节参数模块化思想并结合属性约简算法对参数模块进行属性约简,从实践中定量的找出影响系统性能的主要参数对其进行着重调节快速提高系统性能 ...

The parametric modeling of underwater vehicles based on SolidWorks
, 2012 水下航行体(UUV)外形设计的优劣对UUV的最终性能有着举足轻重的影响。传统的设计方法是通过反复的选型-计算-修改来实现的,这种方法不但效率低下,而且由于选型范围有限,常导致得不到最优解。为解决这一问题,本文研究了UUV的参数化设计方法,并通过自编程序实现了在SolidWorks中的参数化建模。利用iSIGHT优化设计平台强大的过程集成能力和各种寻求最优参数的技术,实现了iSIGHT集成并驱动SolidWorks,Gridgen,CFX等软件并寻求最优参数的设计流程。并针对某UUV,以最小阻力为目标 ...
