  • Publication number: 20240089236
    Abstract: Described are an encoding method and system for ROAs. The encoding method includes the following steps: given a set of authorized IP prefixes an AS which are maintained with an IP address trie. By specifying a sequence of hanging levels on the IP address trie, it is divided into a set of non-overlapping sub-trees, each rooted at a hanging level. A node on a hanging level uniquely defines a sub-tree rooted at it, whose prefix can be encoded as the identifier of this sub-tree. All authorized prefixes covered by a sub-tree can be encoded into a bitmap of 2h bits, where h is the height of this sub-tree. Thus, the set of authorized IP prefixes of an AS is encoded into several tuples (identifier, bitmap).

  • Patent number: 11912595
    Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.

  • Publication number: 20230400519
    Abstract: An SOC estimation method includes calculate an electric quantity value of fixed step size for the mobile power supply, and then sequentially superimpose a unit electric quantity step by step to calculate an accumulated electric quantity from the last moment of SOC change, then compare the absolute value of the accumulated electric quantity with the electric quantity value of the fixed step size to determine whether the SOC value is added/subtracted the fixed step size or kept unchanged, and acquire an initial value of the accumulated electric quantity at the next moment. In above method, the division operation can be replaced by “if judgment” and addition/subtraction operations in actual programming, which greatly reduces the calculation amount for SOC estimation, thereby greatly reducing requirements for chip operational power and peripheral resources and equipment energy consumption, improving the speed and computing stability of SOC estimation.
