Abstract: A power distribution monitoring and control device of an embodiment includes an acquirer and a representative sensor selector. The acquirer acquires a voltage measurement value measured by a plurality of sensors having a communication function installed in a power distribution system. The representative sensor selector selects one or more representative sensors in which the voltage measurement value has a high degree of similarity with that of other sensors installed in the power distribution area from one or more sensors installed in a power distribution area in the power distribution system by referring to the voltage measurement value acquired by the acquirer.

Abstract: A diagnosis data calculation unit 6 calls a representative value of each diagnosis section from the measurement data storage unit 5 corresponding to the diagnosis section, calculates the value as learning data d1 for creating a subspace, and simultaneously calculates it as diagnosis data d2. Normal subspace calculation unit 7 specifies a diagnosis section c on the basis of a calculation result from a normal operation period calculation unit 8 and a high-load time slot calculation unit 18 and calculates a normal subspace that is considered to be normal from a set of the learning data d1. A failure sign detection unit 13 detects presence of a failure sign of the electrical power grid by comparing the diagnosis data d2 with the normal subspace.

Abstract: There is provided a suspicious behavior detection system capable of specifying and identifying a suspicious person exhibiting abnormal behavior. A suspicious behavior detection system is a system to detect suspicious behavior of a monitored subject, by using images captured by a stereo camera. The suspicious behavior detection system has an ambulatory path acquisition unit which acquires ambulatory path information of the monitored subject, and a behavioral identification unit which identifies behavior of the monitored subject based on the ambulatory path information, and automatically determines suspicious behavior of the monitored subject.

Abstract: According to one embodiment, a behavior detection apparatus includes an image acquisition unit, a characteristic acquisition unit, a behavior identification unit, and a detection unit. The image acquisition unit is configured to acquire the image data about an object to detect. The characteristic acquisition unit is configured to acquire characteristic data about the object, from the image data. The behavior identification unit is configured to identify the behavior of the object on the basis of the characteristic data. The detection unit is configured to compare the behavior identified by the behavior identification unit with the scheduled behavioral data representing the behavior the object is supposed to exhibit, thereby to detect abnormal behavior by the object.
