Abstract: A calculating unit calculates, using information indicating temperatures of a fluid mixture at individual locations across a space, heat quantities transferred to the fluid mixture at the individual locations. The fluid mixture is a blend of a plurality of fluids allowed to flow in by a plurality of cooling apparatuses. The calculating unit calculates heat quantities transferred to each of the fluids at the individual locations based on the heat quantities transferred to the fluid mixture at the individual locations, a velocity distribution of the fluid mixture, and flow rate distributions of the individual fluids. The calculating unit evaluates, using the heat quantities transferred to each of the fluids at the individual locations, the degree of contribution of each of the cooling apparatuses to cooling of an object disposed in the space.

Abstract: A light guiding board allows introduction of light into an optically-transparent board member through an incidence surface. Prisms serve to irradiate the light out of the back surface of the optically-transparent board member. A surface emission is realized at the back surface of the optically-transparent board member. In the case where an uneven luminance is generated in the light emitted toward the incidence surface, a flat region is aligned with a dark region. The flat region serves to direct the light to the prisms. The light scatters at a position outside the flat region based on the action of a light scattering structure. A part of the scattered light is directed to the extension of the flat region. The light of a sufficient amount can be introduced into the prisms on the extension of the flat region.
