Development of service-oriented architecture has become more and more maturated. It provides a good solution for integrated design of complex system in effected. provides a better framework for simulation of complex system. This paper introduces concept, principle, essential characteristic and technique advantages of SOA, design integration of independent functions on heterogeneous platforms and reuse...
A recommendation algorithm based on artificial immune network is proposed to deal with the problems of data sparsity and scalability in recommendation technology in the paper. The algorithm can reduce data sparsity and improve the accuracy by using its own mechanisms for dynamic regulation of the immune. The experimental results show that the algorithm has improved the recommend accuracy and has some...
Wireless sensor network coverage to a large extent depends on the deployment of wireless sensor networks. We propose in this work an approach based on an optimized artificial fish-swarm algorithm for wireless sensor networks deployment optimization scheme in a wireless sensor network which is composed of fixed sensor nodes and some mobile sensor nodes. The OAFSA (Optimized Artificial Fish Swarm Algorithm)...
With the development of technology, HPC has become a sign of the integrated power of a conuntry. This paper give a survey of HPC development and point out the development direction. Besides, this paper gives a brief introduction to PVP, SMP, MPP, computer cluster, grid computing and cloud computing, and give a brief contrast to common ways to implement HPC.
In order to make the test questions library system between data integration to realize the information sharing and interaction, this paper puts forward to service oriented SOA based architecture, enterprise service bus ESB message bus, constructs the test model, and the existing questions of the Web services package, hierarchical design of open test questions library system framework.
This article describes the primary frequency control system and AGC problems of an 600MW Ultra-supercritical coal fired units. Introduce the optimal solution in details to these problems. Improve the stability of power grid, reducing the grid frequency fluctuations, and enhance the ability of power grid to against accidents.
In this paper, a prioritized radio resource allocation scheme is studied and analyzed for integrated services in terms of the connection-level QoS. The contributions of our work are threefold. First, a traffic model based on multi-dimensional Markov chain is developed to analyze the performance of integrated services. Second, considering the traffic characteristic of mobile users in different period,...
With the development of information processing technology, DCT has been used more and more widely and the research on DCT algorithm is very much too. But the physical performance of DCT is unclear. To overcome such drawbacks, the paper has proposed 1-D SDCT operation method. First, some new 1-D matrix operation principles are defined. Then, the transform basic matrix used for 1-D SDCT operation was...
Realization problem of active noise control system is studied in the article. The foundational theory and algorithm of active noise control are introduced, the feed-forward adaptive active noise control (AANC) system is presented, the hardware solution of the system is proposed by selecting TMS320VC5509 DSP as the controller. Using the C language, the active noise real-time control system is realized,...
