  • AUTOMATED IMAGE ANNOTATION BASED UPON META-LEARNING OVER TIME

    A principled, probabilistic approach to meta-learning acts as a go-between for a 'black- box' image annotation system and its users. Inspired by inductive transfer, the approach harnesses available information, including the black-box model's performance, the image representations, and a semantic lexicon ontology. Being computationally 'lightweight.' the meta-learner efficiently re-trains over time, to improve and/or adapt to changes. The black-box annotation model is not required to be re-trained, allowing computationally intensive algorithms to be used. Both batch and online annotation settings are accommodated. A "tagging over time" approach produces progressively better annotation, significantly outperforming the black-box as well as the static form of the meta-learner, on real-world data.

  • MECHANISM AND METHOD FOR MANUFACTURING LOW-TEMPERATURE POLYCRYSTALLINE SILICON THIN FILM

    A mechanism and method for manufacturing a low-temperature polycrystalline silicon thin film. The manufacturing mechanism comprises a substrate rinse tank and an ozone gas generating apparatus. The substrate rinse tank is connected to the ozone gas generating apparatus, so that remaining liquor on the surface of a glass substrate can be blown away, and the glass substrate can be in direct contact with ozone gas. Therefore, the surface of a silicon film on the surface is smoother and free of impurities, and after passing through hydrofluoric acid, the glass substrate is in contact with the ozone gas immediately, so that an oxidation film formed on the surface is more uniform, and the crystallization effect is more excellent.

  • METHOD, SYSTEM AND EQUIPMENT FOR AREA MANAGING THE FUNCTION OF USER EQUIPMENT

    A method, a system and an equipment for area managing the function of user equipment are disclosed. Network side receives the request of prohibiting the user equipment in the zone and sets function prohibiting indication according to the request, then down transmits the function prohibiting indication through the system message of the cell covering the zone; the user equipment receives the function prohibiting indication and limits its providing function according to the function prohibiting indication. In the above description, after the network side receives the request of prohibiting the function of user equipment in the zone, it could adjust the network layout to make one or more cells covering the zone, and the cell after the network layout adjusting only covers the zone. The network side sets the function prohibiting indication in the configuring parameter of the cell covering the zone, then down transmits the function prohibiting indication through the broadcast system message. By the scheme of the present invention, some function of the user equipment could be prohibiting in specific situation according to the requirement, thereby the managing problem of multi-function user equipment in a sensitive zone is solved.

  • Diffraction of Gaussian vortex beam in uniaxial crystals orthogonal to the optical axis

    Li, Jia   Xin, Yu   Chen, Yanru   Xu, Shixue   Wang, Yongqing   Zhou, Muchun   Zhao, Qi   Chen, Feinan  

    The diffraction of Gaussian vortex beams in uniaxial crystals orthogonal to the optical axis is studied. Analytical expressions for the components of the diffraction field are derived and illustrated by numerical examples. Results indicate that, upon diffraction of Gaussian vortex beams inside uniaxial crystals, components of the transversal and longitudinal electric fields would vary and show different characteristics. Effects of anisotropic crystals on intensity distributions of Gaussian vortex beams are also investigated. It demonstrates that, upon diffraction, intensity distributions would be distorted and rotated into elliptical profiles with the variation of the ratio of refractive indices. These influences may finally cause the non-symmetry of the intensity distributions of laser beams.
