  • Publication number: 20240139813
    Abstract: The present disclosure relates to an eccentric extreme high-speed-rate laser hybrid manufacturing method for a rotary engineering component. By positioning an extreme high-speed-rate laser direct energy deposition machining head at a predetermined eccentric distance, the damage caused by reflected light to the machining head is effectively reduced, to prolong a service life of the machining head. Also a conventional form of a molten pool in extreme high-speed-rate laser direct energy deposition can be changed, namely from a “falling” form caused by a high-speed movement and a gravity to a “climbing” form. Thus, in extreme high-speed-rate laser direct energy deposition machining, the molten pool has a longer time to fully contact a surface of the rotary engineering component to form desirable bonding performance.

  • Publication number: 20240133144
    Abstract: A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.

  • Patent number: 11968365
    Abstract: Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes, from a coded video bitstream, a syntax element for an adjusted version of an initial quantization parameter (QP) value at a picture level for a picture. The adjusted version is in a range with an upper boundary that is changed with a maximum QP value. Then, the processing circuitry determines the initial QP value of a segment (such as a slice, a tile, a group of tiles and the like) in the picture based on the syntax element and determines a QP value for a block in the segment according to the initial QP value of the segment and adjustments associated with the block. Then, the processing circuitry performs an inverse quantization on quantized data of the block according to the determined QP value.
