Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for identifying a borehole correction factor for determining a true resistivity by selecting a model to apply in identifying the borehole correction factor and applying the model to an apparent resistivity to identify the borehole correction factor. To perform borehole correction, a multiplicative coefficient is needed to apply to the apparent resistivity. A database of this multiplicative coefficient, called the borehole correction factor, is generated based on the borehole correction model. The technology described herein allows operators to avoid time-consuming variable borehole diameter sweeps and complex borehole diameter inversion current used in resistivity logging software.

Abstract: A trusted storage method and system based on a graph structure are provided. The method includes: in a process of initiating a transaction, randomly selecting, by each transaction initiating node, a plurality of witness nodes from a network for witnessing the transaction; packaging, by the witness nodes, transaction data generated by witnessing the transaction to generate blocks; randomly selecting, by the witness nodes, a plurality of storage nodes; sending, by the witness nodes, the blocks to the plurality of storage nodes; and storing, by the storage nodes, the blocks; wherein, for one transaction, all the blocks of all the witness nodes and all the storage nodes form a directed acyclic graph DAG structure. According to embodiments of the disclosure, the directed acyclic graph DAG structure is employed to be matched with an nRW consensus mechanism, so that a supervision problem in a large-scale sharing and exchanging process is solved.

Abstract: A remanufacturing method for a metal part having a damage. The damage groove is divided into a number of levels, and the groove bottom is treated by absorption layer-free laser shock peening to remove surface impurities and to refine surface-layer crystal grains. Then a cladding layer is formed by laser cladding. The process is repeated until the groove is completely filled by the cladding layer to higher than the surface of the metal part and the cladding layer higher than the surface is cut by a mechanical processing and polished, and the upper surface of the laser cladding layer is subjected to large-area overlapped laser shock peening.

Abstract: A method and apparatus for identifying a health status of a contactor includes a processor coupled to a computer readable media. The processor is coupled to the contactor to instruct the contactor to open and close. A database stored in the computer readable media includes operation count variables for the contactor, closing time variables for the contactor, and health status rules for the contactor. The operation count variables and the closing time variables may be inputs to the health status rules to identify the health status of the contactor. A customization program may also be stored in the computer readable media. The customization program enables an operator to modify at least one of the operation count variables, the closing time variables, and the health status rules to affect the identified health status of the contactor.
