  • Publication number: 20240040113
    Abstract: This application provides a video picture decoding and encoding method and a video picture decoding and encoding apparatus. When it is determined that a merge or skip mode is used, if it is determined through decoding that a merge mode with motion vector difference (MMVD) indicator is true, a triangle prediction unit (PU) indicator may not be coded. The triangle PU indicator is coded when it is determined through decoding that the MMVD indicator is false. This reduces a quantity of used coding resources, and can reduce bit overheads of a bitstream.

  • Patent number: 11878444
    Abstract: A method for producing a hollow composite structure, such as a spar beam for use in a wind turbine blade, includes placing fiber reinforcement material around a mandrel within a mold, and curing the fiber reinforcement material. The mandrel is formed from a compressible material having a rigid neutral state with a rigidity to maintain a defined shape of the mandrel during lay up and curing of the fiber reinforcement material. Subsequent to curing, a vacuum is drawn on the mandrel to compress the compressible material so that the compressed mandrel can be drawn out through an opening in the composite structure, the opening having a size such that the mandrel could not be withdrawn through the opening in the rigid neutral state of the mandrel.

  • Publication number: 20240020491
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for machine translation using neural networks. In some implementations, a text in one language is translated into a second language using a neural network model. The model can include an encoder neural network comprising a plurality of bidirectional recurrent neural network layers. The encoding vectors are processed using a multi-headed attention module configured to generate multiple attention context vectors for each encoding vector. A decoder neural network generates a sequence of decoder output vectors using the attention context vectors. The decoder output vectors can represent distributions over various language elements of the second language, allowing a translation of the text into the second language to be determined based on the sequence of decoder output vectors.
