Abstract: A threat detection unit 81 detects a log likely to represent a threat from among acquired logs. A flagging processing unit 82 generates flagged data obtained by flagging the detected log based on a flag condition that defines a flag to be set according to a condition that the log satisfies. A determination unit 83 applies the flagged data to a model in which the flag is set as an explanatory variable and whether to represent a threat or not is set as an objective variable to determine whether the log as a source with the flagged data generated therefrom is a log representing a threat or not. An output unit 84 outputs the determination result indicative of whether the log is a log representing a threat or not.

Abstract: A process for combusting fuels, in particular waste, includes reducing the oxygen mass flow of the underfire combustion gas and increasing the oxygen mass flow of the overfire combustion gas in the event of an increase in the reaction rate or combustion intensity.
