As one of the most popular applications in the Internet,streaming servicesystem has been studied in many approaches to analyze its operation and improve the quality of service（QoS）.This paper proposes a novel dynamic model for the streaming servicesystem based on various technologies,such as peer-topeer（P2P）,content delivery network（CDN）,P2P-CDN,*** the paper,we first present a virtual structure model for the streaming service *** analyzing the novel state which is defined as the number of requests,this paper studies the factors that influences the state that is shown as the peer selection policy and the admission control *** model proposed in this paper shows the interactive process between client and local server,and the one between local server and other ***,some experiments are designed to validate the model.

In this paper, we reported the effective of the tangible user interfaces system to support training basic geometric shape for low-functioning children with autism. The results from the experiment clearly show that the children with autism who study from the TUI training system can learn more shape than conventional treatment. Furthermore, TUI was more attractive and offers a multimedia real time feedback that stimulates children's learning and also increases their attention span rather than the conventional treatment.
Automation is the key concept when designing a service platform, because automation could reduce human's work. Focusing on unstructured information such as text, image and audio, we implemented our service platfor...

The traditional C2R model has two distinct disadvantages;on one hand, the decision-making unit only can be divided into the effective unit and non-effective unit, and it is impossible to distinguish and sort the effective decision-making unit;on the other hand, the weight assignment of the input and output indexes are impractical. In order to solve the existing model defects, it is feasible to introduce two virtual decision-making units, including the optimal decision-making unit and the worst decision-making unit, and build up the objective function model which takes the optimal decision-making unit value as the maximum and the worst decision-making unit value as the minimum, and then take the obtained optimal solution as the public weight vector to calculate the efficiency value of each decision-making unit, so as to implement the effectiveness sorting.

The virtual experiment study is becoming a hot issue of network education study and attracts widespread attentions. This paper describes the important position of network virtual experiment system in the education field. It can conform to the requirements of remote education system and get rid of the restraints of traditional laboratory mode, so as to achieve the full sharing of teaching resources. Combined with the actual development work, this paper introduces the system architecture and drawing engine layer of virtual experiment system, the realization of the simulation frame layer and simulation realization layer. With the development of virtual reality technology and artificial intelligence, the virtual experiment system uses more and more applications of these advanced technologies to improve the user experience. And this is the major development trend of virtual experiment system.
The combination of AR and GIS is introduced into the intelligent terminal, the augmented reality technology was used to provide the navigation service on the real time video. This paper designs and realizes a smart an...

The rapid expansion of cloud offerings poses fundamental tasks for workload management in a large scale server farm. In order to achieve satisfactory Quality of service (QoS) and reduce operation cost, we present a fully distributed workload management system in a large scale server environment, e.g., cloud. Different from existing centralized control approaches, the workload management logic hierarchically spreads on each back-end server and front-end proxy. The control solution is designed to offer both overload protection and resource efficiency for the back-end servers, while achieving service differentiation based on service Level Agreement (SLA). The proposed system can directly work with legacy software stack, because the implementation requires no changes to the target operating system, application servers, or web applications. Our evaluation shows that it achieves both overload protection and service classification under dynamic heavy workload. Furthermore, it also demonstrates negligible management overhead, satisfactory fault-tolerance and fast convergence. (c) 2012 Elsevier B.V. All rights reserved.
