网络大数据基准测试程序拟定与探讨

利用基准测验流程来检验计算机装置处理数据的性能表现是目前采用的主要方式,但是,至今还没有一个成熟完善且被业界普遍遵循的基准检验方案问世,特别是悄然而至的大数据涌潮给当今社会带来了更为艰巨的问题,为求得较理想的测验方案,本文依托具体的大数据平台拟定了一套Hadoop系统的交通事务大数据基准捡验流程.经挑捡若干个属性等级的项目,把流程内容特点进行数量化处理,并选取以同类相聚的计算方法,评估每一个流程的输进参数集合的近似程度,参照类别聚集情况,给基准测验确定了典型的流程及输进参数集合.最终,经过实践检验证明,该基准测验在符合流程内容广泛性的前提下,彻底去掉了基准测验集合中的多余成分.

煤头合成氨厂的节能方案

本文介绍了煤头合成氨生产的两种工艺流程的革新节能方案。根据我国化肥发展长远规划,中型和小型煤头合成氨厂的吨氨总能耗,至2000年应达到1300万千卡以下,与当前中型厂全国平均约为1550万千卡,小型厂约在2400万千卡。

The Six Sigma Approach to Solid Waste Management and Minimization： Moving towards Zero Landfill Facilities

This article provides an overview of an eleven step solid waste analysis and minimization process that is based on the six sigma approach to problem solving that may be applied at a wide variety of organizations. The six sigma approach provides a holistic process that focuses on minimizing defects, in this case, eliminating waste disposed at landfills. As many organizations are moving towards ＂zero landfill＂ facilities, such a process is needed to aid in achieving these goals. The eleven step processes provides details on establishing goals, creating process flowcharts, conducting waste sorts, data collection, establishing baseline data, identifying improvement opportunities, cost justification, executing improvement plans and validating results. The article also includes a case study that applies that eleven step process. The goal of the article is to provide the audience with a structured process to evaluate and minimize solid waste generation based on cost justified improvement opportunities.
