With the rapid development of web service, there are a lot of web services to be chosen. Consumers usually choose the suitable web service when they know little about web services. To address this problem, this paper presents a web service QoS prediction approach based on multi-dimension QoS. It normalizes the multi-dimension QoS parameters and maps each(More)
Modern society depends on the operations of critical infrastructure system (CIs), such as transportation, energy, telecommunications, and water. Characterized by direct and transitive interdependencies, these systems have become so interconnected that disruption of one may lead to disruptions in all. The levels in critical infrastructures must firstly be(More)
With the development of web service, web service composition is used widely. How to guarantee the non-functional requirement of users under the precondition of satisfying functional requirement of users is an important problem in web service composition. To address this problem, this paper presents a web service composition selection approach based on(More)
As a new kind of distributed computing paradigm, web services have been paid more and more attention in recent years. The idea of software as a service is accepted by more and more people. Regarding the web services composition process as a software development process, in this paper we consider web services composition from the view of software(More)
The crosscutting phenomena has been found at architectural level. Using aspects, AOP effectively solves the code tangling problem produced by the crosscutting phenomena at code level. This paper presents an approach to aspect-oriented software architecture design by introducing the concept of aspects into the process of software architecture design. We(More)
This letter presents an iterative detection scheme for orthogonal frequency division multiplexing (OFDM) systems with imperfect channel state information (CSI). In deriving the proposed scheme, channel estimation error is combated by using the theory of variational inference. The proposed scheme deals with the channel impulse response parameters and detects(More)
This paper presents the receiver design of a passband transmitted reference pulse cluster (TRPC) ultra-wideband (UWB) communication system and analyzes its bit error probability (BEP) in the presence of phase noise inherent in local oscillators. Based on a unified model of phase noisy oscillators, a theoretical BEP expression is obtained to evaluate the(More)
Modern societies are increasingly dependent on a set of critical products and services which comprise the Critical Infrastructures (CIs), such as transportation, energy, telecommunications and water. These systems have become so interconnected that disruption of one may lead to disruptions in all. This paper develops an analytical framework with empirical(More)
Service composition is becoming a central aspect in the new paradigm SaaS. In practice, most web services can not be integrated directly into applications because there are some mismatches in their interfaces. These mismatches may arise at different interoperability levels: technical, signature, behavioral, quality of service and semantic. In this paper, we(More)
