According to the AE (Acoustic Emission, AE) signal that caused by the aircraft structural crack, this paper proposed a health diagnosis approach based on ARMA model and SVM (Support Vector Machine, SVM). Firstly, this method apperceives the healthy information of a real aircraft stabilizer with real time by using AE detecting system. And then, deal with the information collected. Secondly, built an...
The risk of the financial market is the focus of global financing institution and supervisory authorities. Correspondingly, the accurate measure of volatility is central to the measure of the Value-at-Risk. VaR is a popular method to computer the finance risk at present, and the key of calculating VaR is predicting volatility exactly. About the measurements of volatility, the first method is the initial...
Free-riding behavior is serious problem in P2P networks, which not only decreased the size of network services but also severely restricted the advantages of P2P System. To solve the free-riding problem, a new micro-payment platform based on trust mechanism is presented. In the platform the nodes can exchange paid services. Accounting mechanism in the platform is used to store service information...
The importance of network organizations gets theoretical and practical recognition. Governance performance in network organizations mainly reflects a region coordination ability and competition ability. However current empirical work has paid little attention to what kinds of dimensions arrangements really do reflect governance performance and reduce transaction costs. Based on the Caofeidian enterprises...
At present the problem of free-riding is serious in P2P network. Free-riding behaviors not only reduce the network scale but only severely restrict the advantage of P2P system. In this paper, an economic model of currency exchange which based on the micro-payment platform with an incentive mechanism is proposed. In the platform, the resources and the services provided by nodes are priced as virtual...
At present free-riding is prevalent in P2P network. Free-riding behaviors not only make the scale of network services decline theoretically from O(n2) down to O(n) but also seriously limit the advantage of P2P. In order to solve the problem, in this paper the micro-payment platform based on incentive compatible mechanism is presented. In this platform the equal services between nodes can be achieved...
Because of long investment cycle, large investment and many uncertainty factors, water project has the characters of irreversibility and postponability. So the investment value of water project is a dynamic one due to these uncertainties. The traditional investment value evaluation model ignores the impact of the above factors, thus can not evaluate the strategic value arising from the risk of water...
A method of spatial load forecasting based on support vector machines (SVM) and cellular automata (CA) is proposed in this paper. Spatial load forecasting can be regarded as a complex problem considering many kinds of factors, while the theory of CA fully reflects the idea "complex systems are from the interaction of simple subsystem??, and is an easy and effective method to deal with complicated...
Water project has the characters of long investment cycle, muti-objectiveness, uncertain and so on. The traditional investment decision-making model usually only makes decision from the perspective of engineering and technical, while ignoring the impact of the above factors. The interactive idea can modify the decision-making results according to uncertain conditions during the course of decision-making,...
