  • Patent number: 10416064
    Abstract: Methods and systems disclosed here include conducting two pressure-dependent permeability tests having the same range of effective stress but two different values of pore pressure. For the test with the higher pore pressure, the permeability is only impacted by the mechanical deformation of the rock, while for the one with lower pore pressure the permeability is impacted by both mechanical deformation of the rock and the Knudsen diffusion. By using the same range of effective stress, the contribution from the mechanical deformation of the rock should be the same. Therefore, by subtracting the permeability with higher pore pressure from the one with lower pore pressure, the impact of Knudsen diffusion and the mechanical deformation of the rock can be determined.

  • Publication number: 20190280814
    Abstract: Embodiments of the application provide a method and device for polar code rate matching in a wireless communication network. A device of the network obtains K information bits. The device generates a to-be-encoded sequence having a length N bits. The to-be-encoded sequence includes the K information bits and L frozen bits. The L frozen bits are placed in L bit positions of the to-be-encoded sequence. The L bit positions are determined according to a rate match manner which is either puncturing or shortening. The device polar encodes the to-be-encoded sequence to obtain the encoded sequence. The device interleaves the encoded sequence to obtain an interleaved sequence and then stores the interleaved sequence into a cyclic cache. The device sequentially outputs M bits of the interleaved sequence from the cyclic cache according to the rate matching manner.
