  • Constructing Service Semantic Link Network Based on the Probabilistic Graphical Model

    Zhao, Anping   Ma, Yan  

    Automatic services collaboration calls for the development of semantically structured service network to maximize the utility of Web services. Service Semantic Link Network (S-SLN) is the semantic model for effectively managing Web service resources by the dependency relationship between services. We provided an effective method for constructing S-SLN based on the graphical structure representation of the dependencies embedded in a probabilistic model. A Markov network is an undirected graph whose links represents probability dependencies. We first learned Markov network structure from Web services data, and then transformed the undirected Markov network structure into a directed graph structure of S-SLN based on the same joint probability distribution. Finally, experimental results show the effectiveness of the method.

  • HALF-AND QUARTER-WAVELENGTH PRINTED SLOT ULTRA-WIDEBAND (UWB) ANTENNAS FOR MOBILE TERMINALS

    The present invention employs slot antennas to make UWB antenna (7) and a quarter-wavelength slot UWB antenna for use in mobile terminals. The slot (8) length, which is related to the lower resonant frequency, is about half (for the half-wavelength slot antenna) or quater (for the quater-wavelength slot antenna) of the wavelength, while the higher resonant frequency is related to a dimension of the tuning stub (14). By modifying the dimensions of the tuning stub (14), good impedance matching of the antenna can be achieved according to the desired operating frequency. This invention can be used for mobile terminals to transmit and receive UWB signals in the frequency range of 3.1GHz-4.9GHz.
