In this study, the carbon nanotubes (CNTs) are successively coated via sol‐gel method with SiO2 (SiO2@CNTs), followed by grafting with 3‐merraptnpropyltrimethnxysilane and oxidation with hydrogen peroxide to yield dual‐modified CNTs (SSiO2@CNTs). The SSiO2@CNTs material is applied to prepared chitosan (CS) based composite proton exchange membranes by the incorporation of various content of SSiO2@CNTs,...
Context identifying based on speech data is important to social services and city management. In a complex application environment, a speech recognition system needs to address two main problems: background noises and large vocabulary search latency. We use the adjustment acoustic model to deal with the scenario adaptation, and we use adjustment dictionary and language module to solve the discourse...
