Based on the analysis of the main issues, which include the basic problems, the main characteristics and the bottleneck troubles, in SoS (System of Systems) research field, we conjecture that we should change the SoS traditional study methodology based on reductionism. We, therefore, propose a new method, named SoSO (SoS Ontology), via keeping the essential concept of SoS, using technology of ontology,...
Weight reflects the essentiality of an index in index volume. Presented a method of determine index weight in security risk evaluation (SRE) based on information entropy. It is a kind of structure analysis method, which constituted entropy model for security risk evaluation of information system and defined subjection function in the first instance, shaped subjection degree matrix of experts' ideas...
Based on abundant data of the civil servant performance appraisal systems home and abroad, the authors make comparison and analysis the Chinese and foreign systems, attempting to give an account of the advantages and disadvantages of China's civil servant performance appraisal system after summarizing the relevant appraisal indicators and evaluation methodology of the system in China. What are in...
In the paper, firstly different wavelet bases are selected to denoise the sunspot activity data through the wavelet transformation, then the EMD analysis method are taken to decompose these two sets of signals, subsequently the physical IMF period of each layer are obtained by using FFT transform. Through the comparisons between the obtained results and the public time-scale of solar activity, we...
In this paper, eco-environmental stress index method to measure the economic development of Tianjin, the size of the ecological pressure on the environment. On this basis, Introduced the Environmental Kuznets (EKC) hypothesis that the conclusions of experience, combined with data on economic growth of Tianjin, Tianjin to build EKC curve empirical analysis of the Tianjin eco-environmental pressure...
In a typical flotation cell circuit, the optimum cell performance depends largely on the ability of the operators to monitor and control the speed at which the froth crosses the lip of each cell. Hence, the froth flowrate is an essential tuning variable for flotation optimal monitoring and control system based on machine vision. However, the froth velocity is difficult to be measured accurately by...
Independent Colleges, as a new model of higher education reform and development, has undergone an unprecedented developing over the past decade, and has gradually become an important part of higher education in China. However, while Independent Colleges has been developing rapidly, its lack of credibility has become one focus of attention in our society. It has become imperative that how to construct...
Strategic alliance among liner-shipping companies is one of the key factors for enterprises to realize win-win strategy, but there also exists huge crises. We mainly utilize method of attribute coordinate to analyze the dynamic alliance behavior among shipping companies, in which relationships between cooperation and such aspects as trade-off cost and repeated gaming is discussed. We further expatriate...
Clustering is used to find out the objects that resemble each other and compose different groups, cluster analysis is an important job in data mining. This article brings the rough set into fuzzy cluster, by using the methods of attributes contracted in the rough set theory to improve the FCM algorithm; the improved algorithm had been proved a high precise ratio.
Transformer is the key equipment of transforming voltage and exchanging power in the power system. It's safe and reliable operation directly influences the safe level of the power system. The risk assessment of transformer is very significant to improve the reliability of the power system. A fuzzy comprehensive risk assessment model of transformer based on Borda number theory is proposed in this paper...
On the basis of the review of literatures in China and abroad, this paper constructs the evaluation index to measure and assess creditor's rights governance of the listed small and medium enterprises in China, and makes an empirical study on the governance situation of 205 Chinese listed SMEs from four foundational dimensions, namely, solvency, debt financing level, assets maturity structure and debt...
