  • Publication number: 20220394359
    Abstract: Resource allocation includes generating a resource allocation identifier corresponding to a resource allocation request. The resource allocation request pertains to allocation of a resource associated with streaming of an audiovisual content item. The resource allocation identifier comprises a first portion and a second portion, the first portion comprising a key, and the second portion comprising information associated with contextual metadata pertaining to the corresponding resource allocation request. It further includes performing a first transmission of a first message including the resource allocation identifier. The first message including the resource allocation identifier is directed to a first address associated with a first entity. It further includes performing a second transmission of a second message. Transmission of the second message causes transmission of the resource allocation request. The second message is directed to a second address associated with a second entity.

  • Publication number: 20220392239
    Abstract: A method for labeling an image, an electronic device, and a storage medium are provided. The method includes the following operations. A remote sensing image is acquired. A local binary image respectively corresponding to at least one building in the remote sensing image and direction angle information of a contour pixel located on a building contour in the local binary image are determined based on the remote sensing image. The direction angle information includes information of an angle between a contour edge where the contour pixel is located and a preset reference direction. A labeled image labeled with a polygonal contour of the at least one building in the remote sensing image is generated based on the local binary image respectively corresponding to the at least one building and the direction angle information.

  • Publication number: 20220291061
    Abstract: The invention discloses a preparation method for a flexible stress sensor based on a composite multilayer conductive material. The method comprises the following steps: S1) preparing a PEDOT: PSS cotton cloth fiber layer; S2) preparing conductive carbon cloth; S3) preparing a metal silver nanowire conductive film; S4) preparing a flexible stress sensor, involving: packaging the PEDOT: PSS cotton cloth fiber layer, the disordered conductive carbon cloth and the silver nanowire conductive film together, and respectively leading a wire out of the PEDOT: PSS cotton cloth fiber layer and the silver nanowire conductive film to obtain the flexible stress sensor. The silver nanowire, the conductive carbon cloth and the PEDOT: PSS cotton cloth fiber cooperate with each other with different different conductivities, realizing the richer resistance variability, the wider resistance change range, higher resistance change rate and higher sensing range up to 70 kPa.
