Title:
DEVICE FOR ESTIMATING EMISSION LEVEL OF SUBSTANCE, METHOD FOR SAME, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/039107
Kind Code:
A1
Abstract:
The purpose is to make possible estimation of the emission level of a substance emitted from an emission site, as well as to increase the accuracy of diffusion predictions based on the emission level. Provided is a device (1) equipped with: an information acquisition section (21) for acquiring location information of observation sites, and observed concentration values and observation times of observations at the observation sites, as well as for acquiring location information of the emission site and the emission start time of the substance; a computing section (22) for using a diffusion model to compute an impact coefficient determined according to the relative location of the emission site and the locations of particles, and according to the relative time of the substance emission time and the observation times at the observation sites; an estimation section (24) for minimizing a residual norm represented using the differences between the observed concentration values at a plurality of the observation sites and calculated concentration values derived through calculations for each of the observation sites, and thereby estimating the emission intensity of particles emitted from the emission site; and an emission intensity correction section (25) for correcting the emission intensity of particles estimated by the estimation section (24), through weights assigned according to the impact coefficient.
