  • Patent number: 10746106
    Abstract: An IGV opening command value is corrected to calculate an actual opening equivalent value that indicates an approximate value of an actual opening. A temperature estimation value, for a case where a mixture of fuel and in-flowing air is combusted, is calculated using the actual opening equivalent value, atmospheric conditions, and an output from a gas turbine. A fuel distribution command value that indicates distribution of fuel output from a plurality of fuel supply systems is calculated on the basis of the temperature estimation value. The fuel distribution command value and a fuel control signal command value that indicates the total flow rate of fuel to be output to the plurality of fuel supply systems are acquired, and respective valve openings of fuel flow rate regulating valves of the fuel supply systems are calculated on the basis of the fuel distribution command value and the fuel control signal command value.

    Abstract: A product recommending apparatus includes an obtaining unit, a classification unit, and a controller. The obtaining unit obtains a purchase history indicating information on a product that a user has purchased, and a promotion history indicating information on a product promoted to a user. The classification unit classifies, using the purchase history and the promotion history, each product into one of a first group of items purchased but not promoted, a second group of items purchased and promoted, a third group of items not purchased nor promoted, and a fourth group of items not purchased but promoted. The controller outputs, using a result of classification done by the classification unit, an item that would not be purchased if not promoted but would be purchased if promoted as an item to be recommended to a user.

  • Patent number: 10161317
    Abstract: A gas turbine drives a power generator by rotating a turbine using combustion gas generated in a combustor as a result of supplying the combustor with fuel and compressed air from a compressor, which is provided with an inlet guide vane at a front stage. An operation control device of the gas turbine enables an IGV priority open flag when the inlet guide vane is not fully open and when the system frequency is lower than or equal to a predetermined threshold value ? or there is a request for increasing the output of the gas turbine. When the IGV priority open flag is enabled, the operation control device sets the degree of opening of the inlet guide vane to be larger than before. Accordingly, the output can be increased without having to increase the turbine inlet temperature, regardless of the operational state of the gas turbine.
