The present paper develops linear regression models based on singular value decomposition (SVD) with the aim of downscaling atmospheric variables statistically to estimate average rainfall in the Chikugo River Basin, Kyushu Island, southern Japan, on a 12-hour basis. Models were designed to take only significantly correlated areas into account in the(More)
Visual simulation using computer graphics and virtual reality has come to be used recently in the production process to enhance the quality of materials and products. In this paper, we propose a simulation of multilayer thin-film interference for pearl material preproduction such as cosmetic development. Pearls manifest a very specific optical phenomenon(More)
