  • Publication number: 20190026884
    Abstract: The present application discloses a method for assessing aesthetic quality of a natural image based on multi-task deep learning. Said method includes: step 1: automatically learning aesthetic and semantic characteristics of the natural image based on multi-task deep learning; step 2: performing aesthetic categorization and semantic recognition to the results of automatic learning based on multi-task deep learning, thereby realizing assessment of aesthetic quality of the natural image. The present application uses semantic information to assist learning of expressions of aesthetic characteristics so as to assess aesthetic quality more effectively, besides, the present application designs various multi-task deep learning network structures so as to effectively use the aesthetic and semantic information for obtaining highly accurate image aesthetic categorization.

  • Patent number: 10008653
    Abstract: A thermoelectric half-Heusler material comprising niobium (Nb), iron (Fe) and antimony (Sb) wherein the material comprises grains having a mean grain size less than one micron. A method of making a nanocomposite half-Heusler thermoelectric material includes melting constituent elements of the thermoelectric material to form an alloy of the thermoelectric material, comminuting (e.g., ball milling) the alloy of the thermoelectric material into nanometer scale mean size particles, and consolidating the nanometer size particles to form the half-Heusler thermoelectric material comprising at least niobium (Nb), iron (Fe) and antimony (Sb) and having grains with a mean grain size less than one micron.

  • Publication number: 20160303795
    Abstract: A fabrication apparatus and method for continuous printing all dimensions of a 3D object that includes a platform and a gas-permeable flexible film that has a carrier surface, wherein a printing area is defined between the platform and the film. A reservoir holding a photocurable resin is in the printing area. A pressure controlled air chamber is adjacent the reservoir and sealed by the film, the film dividing the reservoir and the pressure controlled air chamber. A light exposing device is configured to cure the printing area through the gas-permeable film to form the object from the photocurable resin. A fabrication apparatus and method for printing a 3D object that includes a linear actuator for moving the exposure device that operates with a control device to provide moving exposure images into a resin area larger than the size of a single image.
