    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).

    Abstract: A signal acquisition unit (2020) acquires a signal. From the signal acquired by the signal acquisition unit (2020), a detection signal extraction unit (2060) extracts, as a detection signal, a signal of any frequency band among a plurality of partial detection frequency bands into which the frequency band that is the subject of detection has been divided. A determination unit (2070) determines, in order, for each detection signal corresponding to each of the different partial detection frequency bands, whether the detection signal shows any leakage, and if at least a prescribed number of the detection signals are not showing any leakage, determines that leakage is not taking place.

    Abstract: Disclosed is a structure analyzing device and a structure analyzing method which can analyze a state change of a structure, which is caused before the structure is destroyed, such as a state change of degradation of the structure or the like. A structure analyzing device (10) includes a vibration detecting unit (11) which detects a vibration of a structure, and an analysis unit (12) which analyzes an output signal of the vibration detecting unit (11). The analysis unit (12) analyzes a state change of the structure by comparing a value of resonant sharpness Q, which is measured by use of the following formula (1) in a state existing when carrying out analysis, with a value of resonant sharpness Q which is measured by use of the following formula (1) in a standard state.

    Abstract: Each functional configuring unit of a leak inspection device (2000) operates in the manner that follows. A vibration acquisition unit (2020) acquires a signal indicating tubing vibrations or vibrations propagated from tubing. A filtering unit (2040) extracts a signal of a predetermined frequency band from the signal acquired by the vibration acquisition unit (2020). A characteristic value extraction unit (2060) splits the signal extracted by the filtering unit (2040) into predetermined time intervals, calculates for each split signal the absolute value of each extreme value of the magnitude of the signal, performs for each split signal a statistical process with respect to the calculated plurality of absolute values, and considers values calculated by the statistical process to be characteristic values. A leak determination unit (2080) considers inspection results to indicate the presence of a leak when a determination index value stipulated using the characteristic values is greater than a predetermined threshold.
