Network damage evaluation is a hot research topic in network security area. This paper reviews previous works in the area of network damage evaluation. These studies focus on building an index system and computing the damage by the entropy before and after attacks without taking the correlation of index into consideration, which could results in damage increased, and it cannot express the variable...
Of the many peer-to-peer (P2P) systems in existence, BitTorrent is one of the most appealing that has managed to attract millions of users in the past few years. In this paper we present an extensive study of BitTorrent availability through measurement and analysis. Previous studies are limited to tracker without distributed hash tables (DHT), which have been used widely already. We first discuss...
This paper addresses on design of an optimal proportional integral derivative (PID) controller by applying Lyapunov approach. The optimal PID controller is acquired through minimizing an augmented integral squared error (AISE) performance index that contains control error and at least first order error derivative, and even may contain n orders error derivative. The order of error derivative is determined...
Aiming insufficiency of effective method to depict the coupling balance state of urban traffic systems now, this paper concerns the coupling balance issue of urban traffic supply and demand. The paper presents traffic supply and demand coupling balance index to measure the coupling balance state of traffic systems. The calculative methods of these index are proposed. A simple case is taken for its...
In the system of highly globalized world economy, corporate social responsibility has become main trends and methods, which made the corporate sustainable operation. Modern financial analysis, however, always based on the analysis of economic responsibility, ignored the legal responsibility, ecological responsibility and ethical responsibility. Such neglect has made not only the outcome of decision-making...
It is well-recognized that the main factor that hinders the applications of association rules (ARs) is the huge number of ARs returned by the mining process. To solve this problem, an algorithm for mining concise association rules based on generators and closed itemsets is proposed. Firstly, the concept of concise association rule is proposed, and the rationality of the definition is explained based...
This article embarks from the angle of sustainable development, combined with the power enterprise's development environment and the industrial characteristic, considered fully the power enterprise's economic efficiency and the social efficiency, has designed a performance evaluation index system on the power enterprise, meanwhile four representative power enterprises have been selected to carry on...
Traditional image quality evaluation index cannot explicitly reflect image inpainting quality. In order to make more reasonable measures on image inpainting, this paper proposed an evaluation method based on parameter weight through analyzing the reason for subjective distortion feeling after image inpainting. The new method synthetically evaluates image inpainting quality from three aspects: luminance,...
According to the overall demand of AHP evaluation system, some essential technology of implementing generic AHP evaluation system based on Web services are introduced, which mainly include the storage of AHP evaluation hierarchy based on XML, the implementation of AHP class, the encapsulation, publication, invocation of AHP web service, and the implementation of client application. At last, this system...
