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: Degradation of a pipe can be easily detected. A piping inspection system 1 includes an excitation unit 100, a wave detection unit 210, and a diagnosis unit 220. The excitation unit 100 excites waves of different wave modes simultaneously at a first position of a pipe 300. The wave detection unit 210 detects the waves of different wave modes at a second position of the pipe 300. The diagnosis unit 220 diagnoses degradation of the pipe 300 based on a velocity of one of the waves of different wave modes, the velocity being calculated by using a detection time difference between the waves of different wave modes.

Abstract: A fluid leakage diagnosing device includes: when fluid leakage relating to a pipeline is being diagnosed by employing adaptive signal processing to suppress a component of a disturbance vibration contained in a vibration measured at a prescribed location in the pipeline, an acquiring unit that acquires distribution information that is associated with a characteristic of the pipeline and represents an actual distribution result of a value of a parameter in the adaptive signal processing when performance of suppressing the component of the disturbance vibration satisfies a criterion; an estimating unit that, based on the distribution information, estimates a probability density at which the value of the parameter with which the performance satisfies the criterion exists; and a determining unit that, based on the probability density estimated by the estimating unit, determines a range to search for the value of the parameter in the adaptive signal processing.

Abstract: A control apparatus (2000) computes a waiting time index value for each of a plurality of gates (20) for entering an area (10). The control apparatus (2000) detects, from among the plurality of gates (20), a first gate (20) and a second gate (20) of which relation between the waiting time index values satisfies a first criterion. Herein, the waiting time index value of the first gate (20) is greater than the waiting time index value of the second gate (20). The control apparatus (2000) causes a terminal (30) associated with the first gate (20) to output priority use information, which allows prioritized use of the second gate (20).
