Integrating hybrid systems with existing thermal desalinationplants

In Gulf countries, most power plants are co-generation power desalting plants (CPDP) that generate electric energy and also produce fresh water through the desalination of seawater. This paper provides detailed technical and economical analyses to evaluate a new generation of dual purpose technology that includes the integration of reverse osmosis (RO) processes with existing thermal desalination processes and power generation (triple hybrid system) at Layyah plant, Sharjah, UAE. Hybridization of sweater reverse osmosis (SWRO) and the multi-stage flash (MSF) technology was considered to improve the performance of latter and reduce the cost of the produced water. Moreover, “idle” power in winter (seasonal surplus of unused power) was mainly utilized by RO to further reduce the cost of the hybrid system for six months of the year. Spinning reserve was also used to further reduce the cost of the proposed hybrid system. Integration ofthe three processes of MSF, MED, and RO desalination technologies could be made at different levels through which the resulting of water cost will depend on the selected configuration and the cost of materials of construction, equipment, membrane, energy, etc. Thus, the capital and annual operating costs were calculated for all potential alternatives for various plant capacities. It was found that for all plant capacities, integrated hybrid systems resulted in most cost effective solution. For example, at a capacity of 50 MIGD, the present worth of the cost was calculated to be 588.7, 443.2, and 380 million US$ for MSF, MED, and hybrid RO systems, respectively.     

基于CF卡的大容量存储技术及其在磨削参数检测中的应用

对生产现场进行实时监控或优化工艺参数时,通常需要采集大量的现场数据,因此需要有大容量的数据存储设备和快速稳定的存储过程来实现实时存取。本文简要介绍CF卡的存储原理与操作方式,包括CF卡的内部组织结构、外部接口、读写操作等,着重阐述CF卡在自行开发的磨床磨削参数检测系统中的应用。用便携设备实现了对大容量数据的实时采集和存储。

3D Simulation of Nano-Imprint Lithography

A proof of concept study of the feasibility of fully three-dimensional (3D) time-dependent simulation of nano-imprint lithography of polymer melt, where the polymer is treated as a structured liquid, has been presented. Considering the flow physics of the polymer as a structured liquid, we have followed the line initiated by de Gennes, using a Molecular Stress Function model of the Doi and Edwards type. We have used a 3D Lagrangian Galerkin finite element methods implemented on a parallel computer architecture. In a Lagrangian techniques, the node point follows the particle movement, allowing for the movement of free surfaces or interfaces. We have extended the method to handle the dynamic movement of the contact line between the polymer melt and stamp during mold filling.     

基于MSF的CMM过渡探讨

取得CMM评估是当前软件行业的风潮.MSF产生比较晚,但它集众家之长,形成了MSF自己独特的基本观点和基础模型.CMM的由来有其深厚的历史背景,它为软件组织改进软件设计过程提供了一个切实可行的导引路线图.MSF与CMM也并非天壤之别,有许多相通的地方,从MSF向CMM2过渡就不是很困难,以MSF为基础达到CMM2、争取CMM3是可行的.

MSF-电感耦合等离子体发射光谱法测定钼铁中磷的研究

在用电感耦合等离子体发射光谱法测定钢中磷时，已有的研究报告中大多采用P178．221nm作分析谱线。但因其发射强度低而使测定精密度和检出限不理想。本文在采用多重谱线拟合（MsF）法扣除光谱干扰的基础上进行屏蔽，测定了存在严重光谱干扰的P214．914nm、P213．617nm谱线，同时也测定了没有光谱干扰的P178．221nm、P177．434nm谱线，结果表明，P213nm谱线的测定精密度和检出限最好，比常用P178nm谱线的精密度高，RSD达到小，检出限也比常用P178nm谱线的低。
