In this paper，definitions of knowledge granulation and rough entropy are proposed based on dominance relations in incomplete fuzzy information system, and important properties are obtained. It can be found that using the definitions can measure uncertainty of an attribute set…

This research was about the application of decision support system in agriculture. The subject of study was the corn cultivated in Jilin province, northeast of China. The research synthesized expertise and experience on corn cultivation, plant protection, soil and fertilizer,…

According to the development trend of the act of China's current strategic alliance, this paper elaborates the reason why the success rate of strategic alliance is not high from game theory. The mathematical model based on prisoner's dilemma game and…

Knowledge reduction is one of the important research issues in rough set theory,which applies knowledge reduction theory to reduction the massive task sets in Gloud storage. Atfirst, an equivalence class evolved from subviews will be obtained after task update, Then,…

The multisensor information fusion is a key issue for multisensor system. One of its difficulties lies in the switching of the state of sensor clusters. That is, which direction should the sensor information been fused into at a given moment?…

With the advent of the information age, the network security is particularly important. The secure multiparty computation is a very important branch of cryptography. It is a hotspot in the field of information security. It expanded the scope of the…

As the 750kV substation has the characteristics like timing inconsistency, dual protection configuration and uncertain diagnosis result, a fault diagnosis method of substation with redundant protection configuration based on time sequence fuzzy Petri nets is proposed. In this method, redundant…

On the basis of analyzing the shortcomings of traditional authentication mechanism synthetically, the paper presents a new kind of P2P identity authentication model. In the new P2P Identity authentication model, it authenticates the identity of nodes by using  a new…

Current methods of remotely sensed image change detection almost assume that the DEM of the surface objects do not change. However, for the geological disasters areas (such as: landslides, mudslides and avalanches, etc.), this assumption does not hold. And the…

eScience means sharing documents、information and knowledge in research team and makes convenience to cooperate working. Further more, eScience becomes a social research platform open to anyone who is interested in specifically subject and can easily participate in it.  The goal…
