摘要： A flying body, which prevents others from measuring precise position of the flying body and allows friends to measure precise position of the flying body, is provided. The flying body (10) is provided with a reflector (100), a controller (300) and an anti-reflection section (200). The reflector (100) is provided with a reflective surface, arranged in an aperture, which reflects a radiated laser. The controller (300) generates a control signal on a basis of a state of the flying body. The anti-reflection section (200) prevents a reflection of the laser by the reflective surface on a basis of the control signal.

摘要： To provide an axial flow turbine that can reduce circumferential pressure differences to reduce loss. The axial flow turbine includes: stator blades arrayed in the circumferential direction; and a diaphragm inner ring having an outer circumferential surface that interconnects the stator blades on their inner-circumference side and constitutes a wall surface of a main flow path. The outer circumferential surface of the diaphragm inner ring has depressed portions. Each depressed portion is formed in an area that is on the downstream side of a throat where the distance between a suction surface of one stator blade of a pair of adjacent blades and a pressure surface of other stator blade of the pair of adjacent blades becomes the shortest, and that lies in the circumferential direction within a range of a throat position on the suction surface of the one stator blade to a downstream edge position of the one stator blade. The area includes a downstream edge position of the outer circumferential surface in the axial direction.

摘要： A learning device includes a setting unit configured to set a first value for a parameter of a communication device controlled by a computer using a learned model; a reinforcement learning unit configured to allow a learning model to learn; a model extraction unit configured to extract, as a learned model, the learning model; a model evaluation unit configured to determine whether performance of the learned model has reached first requirement; an updating unit configured to update the first value to a second value when the performance is determined to have reached the first requirement; and a model selection unit. The model evaluation unit determines whether the performance of the learned model updated to the second value satisfies second requirement. When the performance of the learned model updated to the second value is determined to satisfy the second requirement, the model selection unit selects that learned model.
