An inspection system for a fabricated object formed by layering powder includes an acquisition unit that acquires an image of a surface of each of layers, an identification unit that identifies a defect portion (protruding portion or recessed portion) on the surface of the powder and a position of the defect portion based on the acquired image, and a determination unit that determines that an abnormality occurs when the defect portion successively occurs at a same position in the plurality of layers.

Inspection system, inspection method, and inspection program

An edge device is configured to automatically establish a connection with a remote monitoring device when an abnormality has occurred in a plant. The edge device includes a controller configured to detect the abnormality based on data regarding an observation target device, and a connection establishment unit configured to establish a connection with the remote monitoring device such that the remote monitoring device is able to remotely access the edge device when the controller has detected the abnormality and determined that the abnormality matches a predetermined condition, wherein the remote access is a connection for remotely checking a state of the observation target device, or for enabling a remote manipulation of the observation target device.

In the present invention, an input unit receives input of production conditions relating to a plurality of parameters relating to production of a biogas in a biogas production facility. An index value corresponds to an amount of heat per unit quantity of a biogas generated by the biogas production facility under the production conditions. A condition classifying unit classifies the production conditions on the basis of the plurality of parameters and the index value. An output unit outputs information relating to the result of classification by the condition classifying unit.

Biogas quality evaluation device, biogas quality evaluation method, and program

A vibration control device that can achieve the best vibration control effect within an allowable stroke range of a movable mass includes a controller that calculates at least one of a displacement deviation between a target displacement of a movable mass and a displacement of the movable mass detected by a mass displacement sensor and a velocity deviation between a target velocity of the movable mass and a velocity of the movable mass detected by a mass velocity sensor, and generates a control command for making a motor drive the movable mass on the basis of at least one of the displacement deviation and the velocity deviation. The target displacement and the target velocity are set in a manner that the amplitude of the movable mass becomes constant and that phases thereof are delayed 90 degrees with respect to the vibration of a building.
