  • Publication number: 20220144874
    Abstract: The disclosure provides a method for preparing an amphiphilic lignin nanomaterial based on pulping black liquor, an amphiphilic lignin nanomaterial, and an oil sludge detergent. In the disclosure, physical treatments such as ball milling and high-pressure jet homogenization treatment are conducted on alkali lignin at the early stage to adjust the molecular weight and size of alkali lignin and thus to give alkali lignin nanoparticles with uniform particle sizes; and on this basis, a chemical treatment such as alkylation grafting modification is conducted to give amphiphilic lignin nanoparticles with both hydrophilicity and lipophilicity. Due to the nano-size effect, the amphiphilic lignin nanomaterial has a significantly-increased specific surface area (SSA) and effectively-improved surface properties, which can reduce the oil-water interfacial tension, and emulsify the crude oil and peel off the crude oil from the surface of rock particles, so as to achieve the purpose of oil-solid separation.

  • Publication number: 20220129744
    Abstract: A method performed by a processor for permuting dimensions of a multi-dimensional tensor is described. The multi-dimensional tensor contains an array of tensor values in three or more dimensions that are stored in a first storage unit. The array of tensor values is transferred from the first storage unit to a second storage unit by reading tensor values from the first storage that are arrayed along a first dimension of the multi-dimensional tensor and writing the corresponding tensor values to the second storage in locations corresponding to a second dimension of the multi-dimensional tensor. The dimensions of the multi-dimensional tensor may be further permuted by a programmable engine within the processor.

  • Publication number: 20220131579
    Abstract: This application discloses a precoding processing method and an apparatus. The method includes: A base station determines first downlink channel information based on a pilot signal received from a terminal device. The base station receives a precoding matrix indication PMI from the terminal device, determines second downlink channel information based on the PMI, determines a precoding matrix of a downlink channel based on the first downlink channel information and second downlink channel information, and performs precoding processing by using the precoding matrix. In this method, when calculating a downlink BF weight, the base station combines the downlink channel information obtained based on the pilot signal with the precoding matrix indicated by the PMI, to compensate for a quantization error caused by feedback of a single PMI indication. This method improves accuracy of beamforming weights.
