Statistical process monitoring based on improved principal component analysis and its application to chemical processes

In this paper, a novel criterion is proposed to determine the retained principal components (PCs) that capture the dominant variability of online monitored data. The variations of PCs were calculated according to their mean and covariance changes between the modeling sample and the online monitored data. The retained PCs containing dominant variations were selected and defined as correlative PCs (CPCs). The new Hotelling’s T ² statistic based on CPCs was then employed to monitor the process. Case studies on the simulated continuous stirred tank reactor and the well-known Tennessee Eastman process demonstrated the feasibility and effectiveness of the CPCs-based fault detection methods.     

冠心宁注射液中大类成分的含量测定

该实验通过测定冠心宁注射液中的丹参酚酸类成分和糖类成分,为评价冠心宁注射液的质量品质提供理论依据.采用紫外可见分光光度法检测,进行方法学考察,测定10批冠心宁注射液的丹参酚酸和总糖的含量.结果表明,NaNO2-Al（NO3）3显色法用于测定丹参酚酸的含量;苯酚-硫酸法用于测定总糖的含量;10批冠心宁注射液中丹参酚酸和总糖的平均含量分别为93.27mg.10 ml-1、969.87 mg.10 ml-1,分别占固含物的7.66%、79.60%.因此,该方法简便快速、准确可靠,可有效评价冠心宁注射液中80%以上的大类成分的含量.     

WebCT and Its Growth as a Type II Application

Abstract

Maddux, Johnson, and Willis mentioned in 1992 some “yet-to-be-developed types” that “have the potential to be Type II software if they are used in such a way that the user is given the ability to learn in new and better ways.” The authors of this paper will frame the discussion of learning management systems (LMS) around the concept of Type I and Type II applications of computers in education. We suggest that with the new trends of interoperability within WebCT, more researchers will accept WebCT as a potential Type II application. As more interactive learning objects are developed and shared on the WebCT format, it should be easier for instructors to create and teach courses that reflect the value systems expressed in the concept of Type II learning.     

基于神经网络的房地产泡沫预警研究

日益高涨的房地产价格引发了人们对泡沫的激烈争论。本文运用功效系数法计算了综合预警系数,建立了基于BP神经网络的房地产泡预警系统,引入了敏感性分析甄别各指标在预警系统中的重要程度,并且利用北京房地产市场数据对其泡沫进行实证分析,指出该系统对于防范房地产泡沫,评价房地产市场是否处于健康和谐运行状态具有重要意义。
