With the incessant growth of web services on the Internet, how to design effective web service recommendation technologies based on Quality of Service (QoS) is becoming more and more important. Web service recommendation can relieve users from tough work on service selection and improve the efficiency of developing service-oriented applications. Neighborhood-based collaborative filtering has been...
In this paper, a coupling model of multigroup radiation diffusion and heat conduction is considered. Based the domain decomposition method, a new coupling interface boundary condition is designed in order to accomplish the simulation. The numerical results demonstrate the effect of the coupling simulation on the computing efficiency as well as accuracy.
Quality of Service (QoS) has been widely used for personalized Web service recommendation. Since QoS information usually cannot be predetermined, how to make personalized QoS prediction precisely becomes a challenge of Web service recommendation. Time series forecasting and collaborative filtering are two mainstream technologies for QoS prediction. However, on one hand, existing time series forecasting...
The bow-tie structure is frequently cited in the literature of the World Wide Web and in many other areas, such as metabolic networks, but it has never been precisely defined, so that to some extent the concept being discussed remains vague. This paper first provides a formal definition of a bow-tie structure relative to a given strongly connected components. That definition details distinctions which...
Experiments play an indispensable role in cultivating the innovative and practical skills of the students. This paper describes our multi-level and modulized experimental teaching architecture for computer engineering, and its way of implementation. We focus on the cultivation of students' creative and comprehensive abilities. Students from our university have kept receiving honors in national and...
How to analyze and evaluate service availability of flexible supply chain system based on response time effectively is a challenging problem for investigators. To the best of our knowledge, analytical modeling has been mainly used for availability evaluation. However, less attention has been devoted to the analysis and evaluation of service due to long response time especially from the user perceived...
