With the integration of computing, communication, and physical processes, the modern power grid is becoming a large and complex cyber physical power system (CPPS). This trend is intended to modernize and improve the efficiency of the power grid, yet it makes the CPPS vulnerable to potential cascading failures caused by cyber-attacks, e.g., the attacks that are originated by the cyber network of CPPS...
The geographic distance impact has been discussed by scholars for years. The intent of this paper is to investigate the changing pattern of this impact. Moreover, since the development of Information Communication Technologies (ICTs) can affect remote scholarly collaboration, the author also examines its relationship with the changing pattern. The author uses Exponential Random Graph Model (ERGM)...

In recent years, network financial services in china have developed very quickly. However, through empirical analysis, this paper argues that there are still many problems in the development of network financial services of china, such as laws and regulations problem, security problem, network infrastructure problem, etc. To solve these problems, this paper considers that we should formulate and improve...
This paper proposes an available base architecture of integrated education service platform to describe the applications of e-learning in rural area by means of both Internet protocol television (IPTV) and IPQAM-VOD system, which includes four main layers according to different entities. Multiscale solutions for different access equipments are taken into account by considering users' operation habits...
Peer-to-peer overlay, a more promising topology construction, promotes the development of Application Layer Multicast. There have been many studies on the overlay construction and improve the multicast performance. Most of these studies focused on the building period of overlay network or multicast tree. After the overlay construction is established, it will remains stable unless churn of overlay...
To make sure that the distance learning teaching and learning process occurs appropriately, this paper proposes an available architecture to describe the applications of e-learning in rural area by means of Internet Protocol Television (IPTV). According to this architecture, the detail design will be presented. Both education requirement and network restriction are taken into considerations. Furthermore,...
This paper presents an adaptive model of service composition to achieve the optimum profits in the emerging services market, which is based on policy driven and multi-agent negotiation. The negotiation rules will be defined in the policies to determine the conditions for composition and cooperation, such as the accepted range of QoS with corresponding price charge. An agent group will be established...
