Target-based Security Management Architecture Applied to Management Information System     

HU Xiao-bing  YUAN Rui 《保鲜与加工》2005,(2):85-88

In order to implement the security management of management information system (MIS), a target-based security management architecture is proposed. For MIS users, the user interface (UI) is the only way to interact with the MIS system, so all the objects (targets) which need to be managed on UI is registered first, thus for every target the state such as enabled, not enabled, visible, not visible, readonly etc., is assigned. For some users, a set of targets with some state is assigned so that the management granularity in MIS can reach any degree. This approach provides a very flexible way to the security management in MIS.  相似文献   

Analysis on Competition from the View of Law and Economics and the Inspiration     

YUAN Wen-quan  GUAN Hui 《保鲜与加工》2007,(2):158-161168

The establishment of the competition legal system is the response to the social and economical reality. The perfection of the competition legal system needs the support of economic theory. Therefore, analyzing the competition from the law and economic perspective is propitious to perfect the regulation of competition in the law system constantly, guarantee and promote competition, and thus to establish and maintain reasonable and efficient competition order, promote market-economy developing prosperously and harmoniously. The paper uses the study methods of economical and comparative analyze, explore the sorts of competition and their effectiveness, believe that the perfection of the competition legal system should firstly definite that its adjust object is the effective competition with monopoly factor; though the exemption of competition cant be avoid, it continuously appears shrinking trend. The competition legal system will play a more important role in the economical life.  相似文献   

Clustering Analysis for Time Feature of User Power Consumption Based on Structural Self-adaptation ANN     

YUAN Zhong-jun  CHEN Gang 《保鲜与加工》2007,(8):44-48

In view of the important effect of clustering analysis in data mining, the clustering rules and its curve are studied to solve the problem of determining clustering number. A kind of self-adaptation clustering ANN is presented based on SOFM ANN, which can automatically determine the clustering number. Based on practical sales data, the time feature analysis of power user consumption are carried out by using the self-adaptation clustering ANN, whose conclusion has the important referenced values for adjusting power price correspondingly and arranging power producing reasonably.  相似文献   

A Method for State Diagnosis of Grounding Grid     

LIU Yu-geng  TENG Yong-xi  CHEN Xian-lu  YUAN Tao 《保鲜与加工》2004,(2):92-95

This paper discuses the method with which the corrosion of the grounding grid can be diagnosed .A grounding grid can handled as a circuit network. With the application of circuit network graph theory and the fault diagnosis theory of analog circuit and optimization, the fault diagnosis equations can be set up. This equations is figured out by Matlab, and the corrosion status of the grounding grid can be deduced from the result.  相似文献

铁矿粉烧结液相流动性能的特征数方程的建立     

吴铿  申威  杜瑞岭  闫广  门正朝  员晓 《保鲜与加工》2015,(5):26-31

为解决在研究铁矿粉烧结液相流动性能时通常只考虑面积增长率这一终点信息,而没有考虑过程信息的缺陷以及采用多个指标来表征流动性能在使用上的不便,对影响流动性的因素进行了分析,结合量纲分析和白金汉定理推导出了能定量表征流动性强弱的流动性特征数(LD),简化特征数方程后得到等效流动性特征数(Ld Θ)。试验采用了可视卧式高温炉,记录了铁矿粉烧结液相流动的整个过程信息,通过基础实验和对照实验确定液相流动的起点和终点之后,可以得到每一种矿粉相应的等效流动性特征数数值。测量5种铁矿粉在两种方法下的流动性指标,当只考虑面积增长率时的流动性强弱顺序为A>C≈D>B>E,新方法下为Ld ΘA>Ld ΘD>Ld ΘC≈Ld ΘE>Ld ΘB,两种方法下的指标相近,但是综合了各种重要信息的新指标能进一步区分出各个因素对流动性能的影响程度。  相似文献
