  • Publication number: 20160253534
    Abstract: It is impossible to individually identify management target articles in a conventional article management system. An article management system according to the present invention includes a reader antenna that transmits and receives a radio signal; a plurality of tag sheets each including an RF tag and placed on the reader antenna; an RFID reader that reads tag information unique to the RF tag via the reader antenna; and an identification mark attached to each of management target articles and arranged between the management target articles and each tag sheet. On a surface of the identification mark that faces the tag sheets, an identification pattern for identifying the identification mark is formed of a first pattern and a second pattern having a dielectric constant or conductivity lower than that of the first pattern.

  • Patent number: 9319281
    Abstract: Requested processing time of each batch job is complied with. A resource-correction control server calculating an amount of a resource required for setup of a batch application includes an intermediate-process-unit-data acquiring unit that compiles data of completed batch processes as a single data set at a predetermined time point, a resource-correction determining unit that, using the intermediate process unit, determines a process progress rate that is a progress rate of a process at the current time point and whether the process progress rate has reached a required progress rate that is a progress rate required to terminate the batch process within the requested processing time, and an allocation-resource calculating unit that, as a result of the determination, if the required progress rate has not been reached, calculates the amount of the resource required for recovery of the delay based on a delay-recovery-object progress rate and resource information.

  • Publication number: 20160055044
    Abstract: [Object] Proposed are a fault analysis method, a fault analysis system and a storage medium which improve the availability of a computer system. [Solution] Monitoring data is continuously acquired from a monitoring target system comprising one or more computers, and behavioral models which are obtained by modeling the behavior of the monitoring target system are created at regular or irregular intervals based on the acquired monitoring data, the respective differences between two consecutively created behavioral models are calculated and, based on the calculation result, a period in which the behavior of the monitoring target system has changed is estimated, and a user is notified of the period in which the behavior of the monitoring target system is estimated to have changed.

  • Patent number: 8499541
    Abstract: A two-shaft gas turbine is capable of starting premixed combustion without extinguishing a flame. The two-shaft gas turbine includes a combustor and a gas generator controller. The combustor has a premix burner that includes combustion regions in which premixed combustion is to be carried out individually. The gas generator controller controls the combustor. In a method for starting the premixed combustion in the combustor, the gas generator controller selects at least one of the combustion regions in which the premixed combustion is to be carried out, on the basis of a fuel-air ratio, and starts premix combustion in the selected combustion region or separately in each of the selected combustion regions. Further, as the fuel-air ratio is increased, the controller increases the number of the selected region in which the premixed combustion is carried out.

  • Patent number: 8250205
    Abstract: A business process management computer, when the load of a service execution computer etc. is increased, determines the condition of a service call step which is calling a service execution unit, etc. of said service execution computer, etc. If said condition is the bottleneck condition, it determines the condition of the service call step in other process which is calling said service execution unit, etc. If there is no condition other than the bottleneck in that condition, the addition of the resource for said service execution computer, etc. is determined and if there is a condition in which the throughput can be limited, it is determined that the throughput should be limited. In a process which is configured with a plurality of service call steps, when the resource insufficiency has occurred, a means to make the adequate addition of the resource possible can be provided.

  • Patent number: 8041591
    Abstract: A format conversion decision definition generating unit 104 stores information whether or not a response message format from a service unit 134 may be utilized in all later service callings of a business process without format conversion in a repository 121 as format conversion decision information 127, by referring to business process definition information 105 and adapter definition information 106. Then, when a business process operation control unit 132 executes the business process, an adapter operation control unit 133 refers to the format conversion decision information 127 about a target service 134 at the time, and skips the format conversion when information indicating that the format conversion is unnecessary is stored in the format conversion decision information 127.

  • Patent number: 6437424
    Abstract: A barrier film of a SiON film is formed below an interlayer insulating film which is a single layer film or laminated film of an TEOS film or SOG film covering a floating gate 4 and control gate 6. The SiON film which is good in moisture blocking but poor in coverage is covered with another TEOS film which is better in coverage than the SiON film, thereby improving the barrier property of the barrier film. Such a configuration prevents moisture or H atoms contained in the TEOS film or SOG film from being diffused and trapped by the tunneling oxide film 3, thereby improving the trap-up rate and hence endurance characteristic and extending the operation life of a memory cell.
