An estimation apparatusincludes: a correlation index estimation unitconfigured to receive a variable output by a componentas an input, and estimate correlation index information indicating a range that a value of the variable and a correlation can take after a predetermined time, at a normal time; an abnormality degree calculation unitconfigured to calculate an abnormality degree using the correlation index information; and a causal effect estimation unitconfigured to estimate a causal effect expressing an index indicating that an abnormality propagates to a variable output by the component

Estimation apparatus, estimation method, and computer-readable storage medium

A surveillance device according to the present invention includes: a memory; and at least one processor coupled to the memory. The processor performs operations. The operations includes: calculating, based on a value of a parameter that is contained in a received data frame and represents a state of an apparatus, a change in the state of the apparatus; and determining whether the change is included in an allowable range determined in accordance with the state of the apparatus before the change.

Surveillance device, learning device, surveillance method and storage medium

An estimation apparatusincludes: a normal index estimation unitconfigured to estimate, using a second variable output by a second componentthat influences a first variable output by a first component, an index A indicating that the first variable is achieved at a normal time; and an abnormality propagation information estimation unitconfigured to estimate abnormality propagation information expressing an index indicating that an abnormality propagates to a third variable output by a third componentinfluenced by the first component, by changing the first variable.

A communication control device comprises: a transmission unit which transmits, to each of a plurality of communication devices that perform communication using previously allocated communication resources, allocation information indicating the allocation of the communication resources to be used when the communication devices perform communication; and an intermediate state generation unit which, when the allocation of the communication resources to the respective communication devices is changed from a first allocation state to a second allocation state, generates an intermediate state indicating the allocation of the communication resources, on the basis of the first allocation state and the second allocation state, wherein the transmission unit transmits the allocation information to each of the communication devices such that the allocation changes from the first allocation state to the second allocation state via the intermediate state generated by the intermediate state generation unit.

Communication control device, communication control method and recording medium

A storage structure for a light-emitting device is included in a camera body, which also includes a lens mount formed on its front side for attaching a lens barrel and an imaging element arranged on its back side with a center thereof aligned with the center of the lens mount. The storage structure is a concave storage compartment arranged to correspond with an upper part of the lens mount. The light-emitting device is attached to the storage compartment and capable of popping up and down therefrom, the floor of the concave storage compartment is located between a lower edge of an engaging pawl, which is arranged at an upper edge portion of the lens mount, and the upper side of the imaging area of the imaging element.
