    Abstract: A scheduled boarding time acquiring unit acquires a scheduled boarding time of an airport user. A security checkpoint arrival time calculating unit calculates, based on the scheduled boarding time, a security checkpoint arrival time at which the airport user arrives at a security checkpoint. A security checkpoint congestion predicting unit acquires a time series prediction of congestion at the security checkpoint. A privilege determining unit determines, based on the security checkpoint arrival time and the time series prediction of congestion at the security checkpoint, privilege information to be issued to the airport user and its validity period. A privilege issuing unit issues, to the airport user, the privilege information determined by the privilege determining unit.

    Abstract: A correlation function having a clear peak is generated even in an environment in which an ambient noise level is high. A correlation function generation apparatus (100) includes a plurality of input signal obtaining units (101), a changing unit (102), a cross-spectrum calculator (103), a variance calculator (104), and a correlation function calculator (105). The input signal obtaining unit (101) obtains a wave generated by a wave source as an input signal. The transformer (102) obtains a plurality of frequency domain signals by transforming a plurality of input signals obtained by the plurality of input signal obtaining units. The cross-spectrum calculator (103) calculates a cross-spectrum based on the plurality of frequency domain signals. The variance calculator (104) calculates the variance of the cross-spectrum. The correlation function calculator (105) calculates and generates a correlation function based on the cross-spectrum and the variance.

    Abstract: A required time prediction apparatus (2000) acquires utilization facility information and assumed date and time information. The utilization facility information is information enabling to determine a departure facility and a destination facility. The assumed date and time information is information enabling to determine an assumed departure date and time assuming departure from the departure facility or an assumed arrival date and time assuming arrival at the destination facility. The apparatus (2000) estimates a waiting time at each facility being present between the departure facility and the destination facility, regarding a case of assuming departure from the departure facility at the assumed departure date and time, or a case of assuming arrival at the destination facility at the assumed arrival date and time. Then, the apparatus (2000) computes, based on the estimated waiting time, a predicted required time from departure from the departure facility to arrival at the destination facility.

    Abstract: A prediction device 100 of the present invention includes a detection means 121 for, on the basis of a river image that is an image obtained by capturing a river and associated with capturing position information representing a position where the river is captured, detecting river condition information representing a condition of the river at the position where the river image is captured; and a prediction means 122 for, on the basis of the capturing position information, the river condition information, and topography information representing the topography of the river, predicting a river condition representing a condition of the river at a given point of the river. The given point is different from the position represented by the capturing position information.

    Abstract: An arrival time acquisition unit acquires a time at which a user has arrived at an airport. A length of stay information generation unit calculates a length of stay based on the time at which the user has arrived and a scheduled boarding time of an aircraft on which the user is scheduled to board and generates length of stay information including the length of stay. A behavioral characteristic estimation unit estimates a behavioral characteristic of the user based on the generated length of stay information and a behavioral characteristic table. A benefit determination unit refers to a benefit information table and determines benefit information to be distributed to the user based on the estimated behavioral characteristic. A benefit transmission unit transmits the determined benefit information to a terminal apparatus carried by the user.
