Web service schema matching is the preliminary treatment phase of service composition and service mashup. With the entry and exit of large numbers of services on the Internet, it will be difficult to find and suggest the most relevant service candidates for new composition and mashup. In this work, we present an approach for web service schema matching based on characteristic vector consisted of multi-type service parameter information element. This schema matching approach is different form the main syntactical-based and semantic-based matching approaches, and will predict schema relationship more effectively and adaptable for web service. An experiment on real data shows the effectiveness of this approach. © 2011 IEEE.

Tele-presence and tele-immersion systems are growing to be more realistic these years. However, few show practical experiences in Internet wide tele-immersion, especially in acceptable end-to-end delay. We present a framework for multi-party tele-immersion applications that allow remote collab.rative 3D interactions. This framework performs real-time stereo modeling based on the bumblebee cameras. It provides an architecture that supports several tele-immersion nodes to communicate in groups. This paper addresses how to reconstruct, compress and establish the system. The system has been set up in China NGI. Preliminary experiment results show that it's possible to have the delay under 100ms with 320*240 depth map and 640*480 texture images. The framework is also expected to be further extended for interaction with full-body reconstruction. © 2011 IEEE.

An improved continuation power flow method for the AC/DC system is proposed in this paper. The three level control strategies and the coordination of the control modes for DC systems are presented. Firstly, the load-type continuation power flow is introduced in brief. Secondly, the concept of the three-level control and their coordination are proposed. The reactive power control strategy is classified into two categories: 1) Reactive Power under Control and 2) Voltage Magnitude under Control. If the control angle is out of its range, the converter transformer tap should be changed to restore the angle. The voltage or reactive power demand is achieved by coordinating the three level control strategies. Finally, the details of the proposed method are proposed. Numerical simulations show that the approach presented in this paper has advantages in terms of convergence and speed. © 2011 IEEE.

Coverage quality is one critical metric to evaluate the Quality of Service (QoS) provided by wireless sensor networks. In this paper, we address maximum support coverage problem (a.k.a. best case coverage) in wireless sensor networks. Most of the existing work assume that the coverage degree is 1, i.e. every point on the resultant path should fall within the sensing range of at least one sensor node. Here we study the k-coverage problem, in which every point on the resultant path is covered by at least k sensors while optimizing certain objectives. We present tackle this problem under both centralized and distributed setting. The time complexity is bounded by O(k2 n log n) where n is the number of deployed sensor nodes. To the best of our knowledge, this is the first work that presents polynomial time algorithms that find optimal k-support paths for a general k. © 2011 IEEE.

Where IP cores to be mapped must be carefully solved for any given application in order to optimize different performance metrics in Network-on-Chip (NoC) design flow. The optimization of different performance metrics simultaneously may cause a negative effect on each other because of the strong correlation between these performance metrics. In this paper, we propose a multi-objective ant colony algorithm (MOACA) that maps IP cores onto mesh-based NoC architectures. This algorithm is an efficient way to find the pareto-optimal front which optimizes energy consumption and hotspot temperature of NoC. The algorithm has been implemented and evaluated for synthetic generated benchmarks. Experimental results confirm the efficiency, accuracy and scalab.lity of the algorithm. © 2011 IEEE.

The lasting evolution of computing environment, software engineering and interaction methods leads to cloud computing. Cloud computing changes the configuration mode of resources on the Internet and all kinds of resources are virtualized and provided as services. Mass participation and online interaction with social annotations become usual in human daily life. People who own similar interests on the Internet may cluster naturally into scalab.e and boundless communities and collective intelligence will emerge. Human is taken as an intelligent computing factor, and uncertainty becomes a basic property in cloud computing. Virtualization, soft computing and granular computing will become essential features of cloud computing. Compared with the engineering technological problems of IaaS (Infrastructure as a service), PaaS (Platform as a Service) and SaaS (software as a Service), collective intelligence and uncertain knowledge representation will be more important frontiers in cloud computing for researchers within the community of intelligence science.

Although a lot of CAD systems and tools have developed for MEMS, there does not appear to be a means for solid-based modeling. In this paper, a modeling system based on three-dimensional solid model for surface micromachined devices is developed. The system consists of three main modules: fast process simulation and material-based process simulation;automatic mask synthesis based on solid model;collab.rative modeling to support design refinement. Based on a solid modeling core ACIS, the system is implemented in VC++ and some test results are given. The system helps MEMS designers work in a more intuitive mode. © 2011 IEEE.

With the convenient connection to network, more and more individual information including sensitive information, such as contact list in Mobile Phone or PDA, can be delegated to the professional third service provider to manage and maintain. The benefit of this paradigm is, on one hand to avoid the sensitive information leakage when individual devices failed or lost, on the other hand to make only the authorized users access and share the delegated information online anytime and anywhere. However, in this paradigm the critical problems to be resolved are to guarantee both the privacy of delegated individual information and the privacy of authorized users, and what is more important to afford the owners of communication devices to have high level of control and power to create their own particular access control policies. In this paper, we present an approach to implement the personalized access control at third service provider in a privacy preserving way. Our approach implements the critical problems above in this paradigm by using selective encryption, blind signature and the combination of role based access control and discretionary access control. © 2011 IEEE.

Ray-tracing, can produce high-quality images, however, the use of ray-tracing has been limited due to its high demands on computational power and memory bandwidth, especially in the case of satellite imagery. In this paper, we propose a scalab.e parallel ray tracing algorithm of satellite imagery on a cluster of multi-core architecture. The algorithm combines demand-driven and data-driven models in order to reduce communication on the cost of maintaining redundant data. In order to make the most of computer's parallelism and increase computational efficiency, it combines two levels of parallelisms, the TLP parallelism brought by the many core architecture and the inter-node parallelism via MPI and OpenMP. Experiment results show that the algorithm is highly scalab.lity. © 2011 IEEE.
