The revenue between single-price auction and multiple-price auction can not be compared by auction theory. The paper establishes a statistical empirical model and uses the data of China's treasury auction market to examine the revenue between single-price auction and multiple-price auction. The paper has three important conclusions and the single-price auction can prevent the winner's course and collusion. It is the better treasury auction for the seller.

There are various stochastic delay contaminations in the IP networks, which have a great impact on the performance of IP network coordinates system in terms of the delay prediction accuracy and the coordinate stability. Here, from the perspective of keeping the statistical characteristic of delay without a loss and suppressing the abnormal delay jitter, two contamination mitigation methods were proposed respectively, i. e., t-Filter and Δ-Filter. Through the PlanetLab datasets, compared with MP-Filter, the simulation results show that both t-Filter and Δ-Filter can enhance the delay prediction accuracy, the system stability and the system convergence in the more effective methods.
In a distributed virtual environment, one attribute of an object can only be owned by one simulation node at a moment. In current applications, an ownership server will be set up to manage the ownership during the sim...

Cloud Services Delivery Networks (CSDN) constructs a layer distributed server overlay over the Internet, which uses the way to the nearest and on-demand approach providing services to end users. Facing the scale and diversification of the resource demand characteristics of the Internet cloud services, CSDN forms different logical sub-server overlay for different kinds of cloud services. However, most servers and bandwidth resources of CSDN are used to deliver the streaming and downloading kind of cloud services, and the dynamic allocation of their delivery resource is the main research emphasis in this paper. This paper first models the problem to be a multi-dimensional facility location problem, according to the two characteristics: the memory resource and bandwidth resource of this kind of application are the bottleneck resource;the hot contents of this kind of application can be delivered using the Peer-to-Peer mechanisms. After the model analyzed and its NP-Complete proved, we then propose a heuristic algorithm. Finally, using the service delivery cost savings as the performance metrics, while the actual system's operation trace is as the input, the effectiveness of the algorithm are comprehensively assessed.
