In order to develop the communication competencies of the mechanical engineering students, a written technical report consisting of three documents (a report, a set of slides and a script for the slides) is used. Complex aspects of electronics equipments related to EMC, reliability and safety are learned not only by reading information, but also by creating a report. This tutorized task also helps...
How will information from online banks influence the choice of customers? This research uses information processing theory, WOM theory, perceived risk theory and trust theory, in order to find the flow of information from online banks to customers, and the relationships among those issues. Moreover, online banks in Mainland China are the targets of this research.
Take a research in depth on the modeling problem of service path selection based on SON. Firstly, the optimal model is built with the optimal goal of balanced loading and with the functional constraints of users for composed service and multi-QoS constraints. Then the layered method and improved Ant algorithm are adopted to solve this problem. Finally, a simulated emulation is made to the algorithm,...
The reliability of automated system management solutions will increase in importance as the use of cloud computing and data centres expands. As part of a study to improve reliability, this paper provides a classification of faults that can occur in automated system management and proposes a method for determining the severity of such faults. A baseline deployment is compared with an alternate proposed...
Multimedia communication networks, such as the Internet, are heterogeneous in their nature due to the usage of different methods for content distribution. The efficiency of multimedia distribution depends on the variety of communication protocols that are simultaneously running (composed) over different network hosts in order to resolve packet conflicts. A very natural question that arises in such...
This paper establishes a math model of cost-benefit data envelopment analysis based on service capacity evaluation issue of E-commerce system, and presents it as the E-commerce capability evaluation method. This evaluation method based on the basic thinking of DEA. Finally, it verifies the validity and practicality of this model through taking the actual operation of e-commerce service platform as...
Today's Internet is facing many problems which did not take into account in its initial design, such as routing scalability, mobility and security. No matter evolutional or revolutionary solutions that are proposed in recent years, a recognized promising direction is to separate customer network from core network and separate identification from location. In this paper, we sketch out an architecture...
While realizing that the mobile agent technology has significant meaning to network management systems, we also realized the limitation of current mobile agent systems and the need for the combination of mobile agents and Web technology; thus, through adding a queuing mechanism into mobile agent system and combining mobile agent system with the Web technology, an efficient and reliable model for network...
Modern computing environments, such as enterprise data centers, Grids, and PlanetLab, introduce distributed services to address scalability, locality, and reliability. Web services (WS), in particular, improve decoupling, decentralization, and autonomicity within distributed systems. Unfortunately, scale and decentralization introduce additional problems in distributed services management, such as...
Global computing uses Internet-connected PCs volunteered by their owners. These PCs are diverse, volatile, and error-prone. Sophisticated scheduling methods commonly applied in grid computing may not be sufficiently scalable and flexible for global computing environments. This paper shows that it is possible to classify global computing hosts based on simple metrics such as availability and reliability,...
We examine the performance of peer-to-peer (P2P) media streaming using multiple description coding (MDC) and compare it with that of a content delivery network (CDN). In both approaches, multiple servers simultaneously serve one requesting client with complementary descriptions. This approach improves reliability and decreases the data rate a server has to provide. We have implemented both approaches...
