With the development of the peer-to-peer technology, a lot of lookup protocols have come out. Although we can benefit from different protocols separately, our research shows that given a proper model, most of the seemingly different protocols can be classified to a same framework. Since the essence of P2P lookup protocol is to find a specific node from(More)
The paper presents a system for sounds classification of action scenes. We propose to use the matching pursuit (MP) algorithm to obtain effective time-frequency features. The MP-based method utilizes a dictionary of atoms for feature selection, resulting in a flexible, intuitive and physically interpretable set of features. Then apply one-class support(More)
Speed of graphic update and display is the difficult points of WebGIS. This paper proposes a WebGIS acceleration engine solution based on the problems in current WebGIS platforms, which referred to the spatial data model, the indexing and caching, also the client data sharing and collaboration. With this engine, the author suggests new WebGIS architecture,(More)
The workflow mining technology had become a hot research field among computer application. In current mining algorithm, duplicated tasks are hard to be modeled. This pa-per proposes an extended CompDepend-Algorithm able to discovery duplicate tasks. Firstly, a new data structure based on sequence set is designed to describe duplicate tasks. Secondly, rules(More)
This paper analyzed the application characteristics of the GIS in the power industry, and treated the data model and structure of the power GIS. It proposed a conceptual data model “four-dimension, four-division” based on the knowledge base, and proposed a cube structure based on the overall object-oriented power GIS model. The cube structure(More)
The TIN automatic created is a important link in the process of draw contour, however when the distance of measuring points are farther, and the laxity of measuring matrix is bigger different, the structure of Delaunay triangle is often bigger in the measuring point sparse area, which caused the contour precision not to be high. Therefore, this article(More)
Starting from the present theory of CRM and bonding city commercial banks' own features, this article discusses the application steps of CRM in city commercial banks. With the reference to the implementing process of information technology, this article puts forward the implementation scheme of CRM in city commercial banks can be divided into nine basic(More)
Failures detection is a fundamental issue for fault tolerance in distributed system. In order to increase the adaptive capacity, the failure detectors dynamically adjust the detecting quality according to the variations of network. In this paper, a new failure detection model is proposed, which adopts heartbeat detection strategy based on PULL mode. The(More)
BAS (Building Automatic System) network structure in subway station directly determines the performance of their communications, and thereby affects the performance of workstation, OCC (Operation Control Centre), TCC (Traffic Control Centre) and other multi-monitor clients. Cyber Series software and CSC800-type PLC are adopted in this paper to structure the(More)
This paper briefly introduced the research on synthesis load modeling with online statistical measurement-based method. Statistical measurement-based method provides a complementary advantage for synthesis method and overall statistics measurement method by their combination and improvement on the basis of history load data. It offers a better idea to put(More)
