    摘要: Methods, systems, and computer programs for encoding and decoding image are described. In some aspects, an input data block and a prediction data block are accessed. A projection factor is generated based on a projection of the input data block onto the prediction data block. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. A residual data block is generated based on a difference between the input data block and the scaled prediction data block. In some aspects, a prediction data block, a residual data block, and a projection factor associated with the residual data block are accessed. A scaled prediction data block is generated by multiplying the projection factor by the prediction data block. An output data block is generated by summing the residual data block and the scaled prediction data block.

    摘要: A method for regulating the structure and properties of the composite nanoabsorbent is provided. This method uses nanoporous chloromethylated polystyrene-divinylbenzene beads as the support material and adopts in situ precipitation method to load dissociative functional nanoparticles thereon; the composite nanoabsorbent of different absorption capacity and absorption speed can be prepared through regulating the pore structure, which is realized herein by means of starting crosslinking reactions through heating chloromethylated beads under existence of the swelling agent and the catalyst; through changing the proportions of different components in the reaction system, modes of heating and time of reaction, the polymer support with different pore structures can be prepared. This invention can successfully regulate the distribution and size of inorganic nanoparticles; the composite nanomaterials prepared by the resin of different degrees of crosslinking present different structures and properties, and the specific structure and properties can be selected in order to meet practical requirements.

    摘要: A Method and apparatus for a user handing over to a home NodeB are provided. The method comprises the following steps: when the user initiates a handover procedure from a source NodeB to a target home NodeB, a target home NodeB gateway receiving a relocation request message from a mobility management unit of a core network; the target home NodeB gateway generating a user context for the user according to the relocation request message, allocating a user context identifier for the user context, and sending the user context identifier and the relocation request message to the target home NodeB; and when receiving a relocation request acknowledgement message replied by the target home NodeB, the target home NodeB gateway sending the relocation request acknowledgement message to the mobility management unit of the core network. The application of the above technical solution can ensure the handover of a user to a home NodeB which serves as a target NodeB successfully.

    摘要: An artificial biomembrane and a method for manufacturing the same. Raw film-forming materials, such as polyvinyl alcohol, sodium alginate and sodium carboxymethyl cellulose, are dissolved in water to form a glue liquid, into which a mixture of coal-based activated carbon powder, diatomaceous earth powder sodium acetate and single strain or multiple strains of microbial cells are added. The resultant glue liquid is immobilized using powder beds or fluidized beds to form artificial biomembranes. The artificial biomembranes can be manufactured in a large-scale, with simple process of immobilization, high efficiency and low cost. The artificial biomembranes can be applied to ecological restorations and different polluted water environments, such as industrial wastewater, sewage, fishing water, landscape water, flowing water and the like.
