Abstract: Provided are an information processing device and the like capable of presenting a user-desired observation result to the user rapidly in a case where observation is performed using observation satellites. The information processing device comprises receiving means for receiving a request to acquire observation data based on a result of observing a designated range at a designated time, specifying means for using orbit information for a plurality of observation satellites to specify an observation satellite with which the designated range can be observed on or after the designated time from among the plurality of observation satellites, and acquiring means for acquiring requested observation data, that is, the observation data which is generated by the specified observation satellite and which is based on a result of observing the designated range on or after the designated time.

Abstract: The fluidity of a plastic fluid, cement mortar for example, is measured by passing the fluid through a flow passage packed with an aggregate for simulating an actual mould, measuring the flow pressure, and measuring the quantitative flow coefficient between the fluid and the flow passage. The pressure remaining in the passage after the fluid has been poured into the passage and after the flow speed has been decreased to zero or the pressure after a quantity of the fluid has been added to the passage and prior to the discharge of the fluid from the passage is measured to determine the relative shear stress yielding value. Thereafter, the fluid is caused to flow to determine again the relative shear stress yielding value, and the relative closure coefficient is determined by the difference between said two relative shear stress yielding values.
