Sinosteel：Extraordinary Moves in Industry Chess

Among the Fortune 500 firms,more and more images from China emerge out.On the 2008 list,Sinosteel Corporation,a landmark group of China industries quietly squeezes into the candidate line.As the largest steel service ＆ trade enterprise,its sales reached at RMB 111.24 billion,with a year-on-year increase of 83.03 percent,and the profit grew by 180.03 percent.On the Sinosteel 2008 Work Meeting,the president Huang Tianwen uttered,＂In the coming year,we will work for US$20 billion sales,and look forward to getting a position in Fortune 500 firms for ourselves.＂     

一种新的基于贝叶斯频谱估计的传输线长度测量方法

根据双臂电桥原理搭建出实验电路进行数据采集,再应用贝叶斯频谱估计算法对测得的数据进行分析,得出反射频率周期,然后根据反射原理推算出人工传输线的长度。由于在检测方法和分析方法上的改进,在传输线长度的测量精度上获得了很好的效果。在实验中,根据先验知识和理论得出一个特定的模型方程;在实际应用中如果能够找到一个合适的模型方程,那么就可以运用贝叶斯频谱估计方法进行分析,因此贝叶斯频谱估计算法有着非常广泛的实用价值。     

体验营销与广告标语

市场营销是一种信息的传播及其反馈过程。广告用语是一种能产生市场效用的经济语言。体验营销具有即时性、差异性、互动性、主动性等特征,其根本原因在于消费者的体验需求。广告标语中的体验形式为感官、情感、思考、行动和关联,可以使产品在未被使用之前就增加其体验价值。     

沿东陇海线地区经济开放度分析与评价

经济全球化环境下,正确估价某一地区的经济开放度,是衡量一国或地区经济对外开放程度的综合性指标,也表示一国或地区经济融入国际经济的程度和对国际经济的依存程度。对指导地区经济健康发展具有重要的作用     

浅谈“六统一”的设计及应用

目前江苏省正在推广按照＂六统一＂原则提出的典型设计,本文主要探讨了按照＂六统一＂设计后的220kV线路保护与未按原则之前的不同之处,选取三个问题进行讨论,包括线路电压互感器的普遍使用,两套保护的重合闸配合,母线保护的失灵启动回路等,提出一些在变电二次工作中会遇到的问题,供现场的施工人员参考和借鉴。     

中国财政风险两大警戒线的测算研究

在国际金融危机仍在蔓延和深化的条件下,我国于2008年重启的积极财政政策将持续较长时间,但由此导致的财政风险将对积极财政政策能走多远产生重要影响.本文在模型推导基础上,对我国财政风险两大警戒线进行实证测算,认为运用<马约>中所谓的"国际警戒线"来判断中国财政风险状况并不科学合理.主要研究发现:(1)我国财政赤字率和公债负担率的警戒线分别约为4.05%、49.05%,这与<马约>中的财政标准有较大差异.(3)以测算出的财政风险两大警戒线为评判基准,发现目前我国财政风险状况尚处于可控的、安全的区间,如2008年我国实际的财政赤字率和公债负担率尚与警戒线值分别相差约3.68%和31.33%,即具有较大的政策回旋余地和操作空间.     

Using Simulation and Data Envelopment Analysis to Compare Assembly Line Balancing Solutions

This paper presents a technique for comparing the results of different assembly line balancing strategies by using Data Envelopment Analysis (DEA). Initially, several heuristics--which can be thought of as assembly line balancing strategies--were used to solve seven line-balancing problems. The resulting line balance solutions provided two pieces of information that were of particular interest: the number of workers needed and the amount of equipment needed. These two items were considered inputs for DEA. The different line balance solutions were then used as layouts for simulated production runs. From the simulation experiments, several output performance measures were obtained which were of particular interest and were used as outputs for DEA. The analysis shows that DEA is effective in suggesting which line balancing heuristics are most promising.

Discussion on the Benefits Distributing Structure in Village Land Deal

According to everyone average welfare value of land resources; this paper constitutes the base line of glebe usufruct deal value by analyzing the factors, which are affecting glebe usufruct deal value. Having adopted share＇s quotient of ownership and contracting power, the paper erects assigning mechanism to the income of glebe deal. Because of the share dynarnicity being adopted which shows the flexible strong points, the shares of ownership and contracting power avoid many unnecessary otiose disputes on income of glebe deal, adding the stability to the glebe usufruct deal. It is beneficial to the freedom flow and validity manufacture factor installment and also to the nonagricultural changing course.
