  • Publication number: 20200012543
    Abstract: A technique for improving determination of handling of guides to events generated in an information system is provided. An event monitoring apparatus for monitoring an event including an event message indicated by a character string related to a phenomenon occurring in an information system includes a guide storage unit that stores a plurality of guides including guide messages indicated by a character string and indicating a method of handling the event and a threshold relating to similarity between the guide messages of the guides and event messages in association with each other; an event storage unit that records the event from the information system; and a guide provision unit that calculates the similarity between the event messages included in the event and the guide messages of the guide and associates a guide whose similarity exceeds a threshold with the event.

  • Publication number: 20140162134
    Abstract: A gel electrolyte secondary cell includes a positive electrode, a negative electrode and a gel electrolyte. The negative electrode includes a current collector, and a mixture of powders of a graphite carbonaceous material and a binder. The powders of the graphite carbonaceous material include sintered meso-carbon micro-beads. The gel electrolyte includes an electrolyte salt, a non-aqueous solvent and a high-molecular weight material. The non-aqueous solvent includes propylene carbonate and ethylene carbonate. A content of propylene carbonate ranges from 35 mol % to 75 mol %. The binder is in an amount 1 to 20 wt % based on total weight of the powders of the graphite carbonaceous material. The meso-carbon micro-beads can suitably decrease the impedance and the discharge capacity loss, thereby increasing the discharging capacity and/or charging/discharging efficiency of the gel electrolyte secondary cell.
