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)
PURPOSE To evaluate the diagnostic value of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS A systematic, comprehensive literature search was conducted in PubMed (2004 [Gd-EOB-DTPA was first approved in Europe in 2004] to April(More)
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)
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)
Bone cancer pain presents a clinical challenge with limitations of current treatments. Many patients seek additional therapies that may relieve pain. Many external applications of traditional Chinese medicines (EAs-TCMs) have been evaluated in clinical trials, but fewer are known about them outside of China. The objective of this study is to assess the(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)
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)
For service robot vision localization requirements, the localization technology research based on the image SIFT characteristic was introduced. The space examination, the precise positions of characteristic points, the direction parameters of the assigned operator and the description of the characteristic point were analyzed. At the same time, the stability(More)
Due to the weak signal energy of the backscatter link, traditional RFID communication is easily affected by noises, interferences, and interceptions from the environment. To solve the problem, a novel passive UHF RFID tag baseband processor enhanced with spread spectrum technique is presented in this paper. In addition, power-saving strategies are proposed(More)
