  • Publication number: 20230412295
    Abstract: Embodiments of this application provide a method and an apparatus for service processing in a terminal device. The terminal device is provided with a first card and a second card. When the terminal device is using the second card for performing a voice service, if the terminal device receives a data service request that requires the first card for implementation, the terminal device may search for a cell corresponding to a first band. The cell corresponding to the first band is a cell accessed by the first card before the first card enters an idle state. Therefore, when the terminal device has found the cell corresponding to the first band, the voice service of the terminal device is not interrupted. The terminal device can implement both the data service of the first card and the voice service of the second card, allowing more usage scenarios for the terminal device.

  • Publication number: 20230343128
    Abstract: The present disclosure provides a juvenile fish limb identification method based on a multi-scale cascaded perceptual convolutional neural network. The method includes the following steps: acquiring a video sequence of a juvenile fish, dividing a fish body into five non-overlapping parts, performing semantic annotation on the five non-overlapping parts, and taking the five non-overlapping parts as an input of the multi-scale cascaded perceptual convolutional neural network; and using a convolutional layer as a feature extractor, performing feature extraction on an input image containing the annotation of each limb, inputting extracted features into an Attention-region proposal network (RPN) structure, determining a category of each pixel, and generating a limb mask of each limb category using a multi-scale cascade method. According to the method, the limbs of the juvenile fish can be efficiently and accurately identified, and technical support is provided for posture quantification of the juvenile fish.

  • Publication number: 20150068574
    Abstract: Thermoelectric materials with high figures of merit, ZT values, are disclosed. In many instances, such materials include nano-sized domains (e.g., nanocrystalline), which are hypothesized to help increase the ZT value of the material (e.g., by increasing phonon scattering due to interfaces at grain boundaries or grain/inclusion boundaries). The ZT value of such materials can be greater than about 1, 1.2, 1.4, 1.5, 1.8, 2 and even higher. Such materials can be manufactured from a thermoelectric starting material by generating nanoparticles therefrom, or mechanically alloyed nanoparticles from elements which can be subsequently consolidated (e.g., via direct current induced hot press) into a new bulk material. Non-limiting examples of starting materials include bismuth, lead, and/or silicon-based materials, which can be alloyed, elemental, and/or doped. Various compositions and methods relating to aspects of nanostructured theromoelectric materials (e.g., modulation doping) are further disclosed.

A method of producing a nanostructure material comprises coating a single crystal substrate with a catalyst film to form a catalyst coated substrate; annealing the catalyst film by supplying a first promoter gas to the catalyst coated substrate at a first temperature and a first pressure; and supplying a second promoter gas and a carbon-source gas to the catalyst coated substrate in a substantially water-free atmosphere at a second pressure and a second temperature for a time period to cause growth of nanostructures on the catalyst coated substrate. The nanostructure material is used in various applications.

  • Patent number: 6863942
    Abstract: One or more highly-oriented, multi-walled carbon nanotubes are grown on an outer surface of a substrate initially disposed with a catalyst film or catalyst nano-dot by plasma enhanced hot filament chemical vapor deposition of a carbon source gas and a catalyst gas at temperatures between 300° C. and 3000° C. The carbon nanotubes range from 4 to 500 nm in diameter and 0.1 to 50 ?m in length depending on growth conditions. Carbon nanotube density can exceed 104 nanotubes/mm2. Acetylene is used as the carbon source gas, and ammonia is used as the catalyst gas. Plasma intensity, carbon source gas to catalyst gas ratio and their flow rates, catalyst film thickness, and temperature of chemical vapor deposition affect the lengths, diameters, density, and uniformity of the carbon nanotubes. The carbon nanotubes of the present invention are useful in electrochemical applications as well as in electron emission, structural composite, material storage, and microelectrode applications.
