Low-light image enhancement (LLIE) aims to recover illumination and improve the visibility of low-light images. Conventional LLIE methods often produce poor results because they neglect effect noise interference. Deep learning-based focus on learning a mapping function between images normal-light that outperforms conventional methods. However, most deep cannot yet fully exploit guidance auxiliary priors provided by in training dataset. In this paper, we propose brightness-aware network with...

Electrode erosion and particulate sputtering would be inevitable in gas spark gap, which could affect its dielectric performance reliability. To analyze the process of electrode-to-electrode this paper conducted discharge experiments between Mo W electrodes analyzed results with scanning electron microscopy (SEM). Results indicated that main began particles to each other after 10 shots, distribution range extended larger velocities angles. However, even only one shot, particulates are...

Abstract In order to meet the heat dissipation requirements of high-power CPUs and make data center servers more energy-efficient, this paper studies a composite thermosiphon radiator for 400WCPU. The cooling performance degree optimization compared with ordinary pipes are studied under different source power air volume conditions. results show that thermal resistance is lowest at 400W it has little dependence on volume. Compared common pipe radiator, condenser been greatly optimized,...
