Threshold proxy signature is more practical, flexible and secure than traditional proxy signature and multi-proxy signature schemes. However, the majority of existing identity-based threshold proxy signature schemes is still inefficient and impractical. Cloud services allow users to create, store, edit, and read electronic documents on the internet conveniently. While access control mechanisms enable...
TIN date is wildly used in digital-agriculture area, but there is a drawback in TIN creating from Contour, especially in agriculture-application, that is flat-triangle. Some researchers have study on this and a lot algorithm have been brought out, in this paper, a improved algorithm of solving the problem about flat-triangle is proposed base on recursive thought. This algorithm is used in the 863-project...
It is important but challenging to understand the throughput performance in wireless multi-hop networks. Most previous works show that the M/M/1 model is accurate enough for throughput analysis most of the time. However, we notice that without considering the interrelationship between the traffic on nodes, the M/M/1 model is quite inaccurate sometimes, especially on the typical chain topology. Therefore...
An approach to model and quantify a userpsilas Web search interests using the userpsilas navigational data is presented. The approach is based on the premise that frequently visiting certain types of content indicates that the user is interested in that content. The proposed approach can be divided into three steps: monitoring the userpsilas navigational data; using the cumulative weight to determine...
