一种信息审计系统中的多关键字匹配算法

针对审计系统中搜索大量审计数据的需要,设计了一种基于哈希表机制的多关键字匹配算法.该算法把关键字集合储存到哈希表中,并为关键字集合建立了两个过滤表和一个关键字长度类型表.在查找过程中,对未经过滤表验证的字符串不再进行匹配查找,同时,关键字长度类型表的使用减少了循环的次数.测试结果表明,该算法在速度和精度上都优于BM和mgrep算法.     

Elaboration and Properties of Nanocomposite Structures Based on Crown Modified Platinum Nanoparticles

1 Results This paper presents the development of platinum nanocomposites structures based on organically modified c.a.2 nm core platinum nanoparticles.The chemical modification of the 4-mercaptoaniline functionalized particles by various in coming molecules is evidenced and precisely quantified.The particles can be dissolved like molecules in various solvents depending on the features of the new crown and X-rays shows that the interparticle distance is affected by the crown modification.These platinum n...

Decision trees for forecasting

Recent years have seen an increasing cross-fertilization between the fields of decision analysis and forecasting. Decision-analytic models often require forecasts as inputs, and aspects of the Bayesian decision-theoretic framework underlying decision analysis have proved useful to forecasting, particularly in contexts where subjective judgemental inputs are required. This paper describes the use of decision tree analysis for forecasting and illustrates its use for corporate divisional forecasting and planning. A specialized decision-analytic technique, acts as events, is also described and illustrated to forecast a new product's earnings. Conclusions are drawn about the applicability of decision analysis for forecasting.
