The application of the traditional planar acoustics method is limited due to the low accuracy when computing the echo characteristics of underwater targets. Based on the concept of the shooting and bouncing ray which considers multiple reflections on the basic of the geometrics optics principle. this paper presents a more efficient GPU-accelerated multiresolution grid algorithm in the... https://www.markbroyard.com/best-grab-sukin-hydrating-body-lotion-250ml-fashion-save-extra/
