  • Publication number: 20240105370
    Abstract: The present invention discloses a high-entropy soft magnetic alloy with 900 K high-temperature resistance, comprising Fe, Co, Ni, Si and Al, and the atomic percent of the alloy composition is expressed as FexCoyNizSimAln, wherein x=40%-80%, y=20%-60%, z=0-30%, m=0-20%, n=0-20%, and x+y+z+m+n=100%; the atomic percent of other doping elements is p=0-5%, and 0.5?m/n?3; the performance indexes of the material include: at room temperature, saturation magnetization Ms=90-150 emu/g, and coercive force Hc=0.1-15 Oe; and at 900 K, saturation magnetization Ms=70-130 emu/g, and coercive force Hc=0.1-25 Oe.

  • Publication number: 20230351372
    Abstract: A gateway encryption service is used to ensure consistent, source independent tokenization for payment accounts and synchronizing payment account information with merchants. A consistent, evergreen merchant-facing token is generated and used for each payment account for the merchant, ensuring that regardless of the payment method used by the customer (e.g., plastic card point-of-sale, pay wallet, saved card information) for the same underlying account, the merchant has a single token. Further, if the account number for the underlying payment account changes (e.g., the card expires or is stolen) the merchant-facing token remains consistent. The evergreen token ensures that the system functions more efficiently, saving resources in processing and storage and ensuring less network traffic for failed transactions. The system further implements encryption and security despite the consistent tokenization, further saving resources.

  • Publication number: 20200346675
    Abstract: Disclosed is a method for arranging parallel maintenance lines for railway wagons, including: (1) obtaining design information of the parallel maintenance lines; (2) initially designing the parallel maintenance lines; where the maintenance lines comprise a disassembly line and an assembly line parallel to each other, and the disassembly line and the assembly line are connected through a track; (3) establishing a multi-objective mathematical model for solving a parallel maintenance line balancing problem, where the multi-objective mathematical model comprises a first model for minimizing the number of workstations, a second model for minimizing an idle time of the workstations and a third model for minimizing the number of maintenance resources; and (4) obtaining a feasible solution using an intelligent optimization algorithm.
