  • Publication number: 20240184578
    Abstract: Methods and embodiments of a high-performance parallel multi-literal matching algorithm called NeoHarry. A chunk of data comprising a character string comprising n bytes is sampled for a byte stream, and data in the sampled chunk are pre-shifted to create shifted copies of data at multiple sampled locations. A mask table is generated having column vectors containing match indicia identifying potential character matches. A look up of the mask table at multiple sampled locations using the pre-shifted data is performed for a target literal character pattern. The mask table lookup results are combined to generate match candidates and exact match verification is performed to identify any generated match candidates that match the target literal character pattern. NeoHarry uses a column-vector-based shift-or model and implements a cross-domain shift algorithm under which character patterns spanning two domains are identified.

  • Publication number: 20240181516
    Abstract: Disclosed are an attractive electromagnetic flanging method using a stepped magnetic field shaper for a small metal pipe fitting, and a device. The problems that an existing electromagnetic flanging method uses a dual-coil and dual-power system, is complicated in control and coordination, and cumbersome in assembly configuration, and a forming effect of using a single coil system is poor are solved. The superior performance of a magnetic field in a specific area can be strengthened during flanging forming through the special stepped magnetic field shaper, such that an effect of replacing provision of an axial background magnetic field coil is achieved. The method solves the problem of insufficient radial electromagnetic force in the single coil system, and simplifies the problems of complicated control and coordination and cumbersome assembly configuration of the dual-coil system.

  • Patent number: 11429574
    Abstract: Disclosed embodiments provide a computer-implemented technique for creating a log chain from multiple software component logs. The log chain can include log information from multiple software components that interact with each other. In embodiments, a locality-sensitive hashing technique is used to create a signature of a log chain. Machine-learning systems are trained with log chains generated from test execution, and/or log chains from incidents with deployed software. In embodiments, logs are pre-processed by tokenizing and trimming. Logs from various components that interact with each other may be combined into a temporally sequential log chain. The signature of the log chain may be used to identify additional information about the error from a machine-learning process that was trained on previously generated log chains. In this way, the time required to identify a problem can be significantly reduced, resulting in increased reliability and availability of complex computer systems.
