This paper reports on the NTIRE 2022 challenge perceptual image quality assessment (IQA), held in conjunction with New Trends Image Restoration and Enhancement workshop (NTIRE) at CVPR 2022. is to address emerging of IQA by processing algorithms. The output images these algorithms have completely different characteristics from traditional distortions are included PIPAL dataset used this challenge. divided into two tracks, a full-reference track similar previous new that focuses no-reference...
This paper reports on the NTIRE 2023 Quality Assessment of Video Enhancement Challenge, which will be held in conjunction with New Trends Image Restoration and Workshop (NTIRE) at CVPR 2023. challenge is to address a major field video processing, namely, quality assessment (VQA) for enhanced videos. The uses VQA Dataset Perceptual (VDPVE), has total 1211 videos, including 600 videos color, brightness, contrast enhancements, 310 deblurring, 301 deshaked 167 registered participants. 61...
Measuring the perceptual quality of images automatically is an essential task in area computer vision, as degradations on image can exist many processes from acquisition, transmission to enhancing. Many Image Quality Assessment(IQA) algorithms have been designed tackle this problem. However, it still remains unsettled due various types distortions and lack large-scale human-rated datasets. In paper, we propose a novel algorithm based Swin Transformer [31] with fused features multiple stages,...
It is shown from the experimental results of existing Hall thrusters that erosion phenomena occur in magnetic poles when maximum field located plume region. The developed Particle-in-Cell model used this paper for simulation research on pole thrusters. show region, there a large potential drop between channel outlet and pole. Therefore, low-energy ions close to plane are accelerated bombard surface, which an important reason erosion. Moreover, ion flux energy bombarded under two conditions...
It is indispensable to achieve antireflection and protection of the sapphire (i.e., Al2O3 single crystal) infrared window, especially in extreme environments such as high temperature high-energy laser irradiation. Here, double-layered SiO2/HfO2 films were deposited on by RF magnetron sputtering with subsequent annealing. The annealing HfO2 pure oxygen facilitates crystallization, well an obvious increase O/Hf ratio. influences interlayer film microstructure, adhesive strength, stress,...
Abstract In this study, the neutral gas distribution and steady-state discharge under different channel lengths were studied via numerical simulations. The results show that with a length of 22 mm has advantage comprehensive performance. At time, magnetic field intensity at anode surface is 10% peak intensity. Further analysis shows high-gas-density zone moves outward due to shortening length, which optimizes matching between flow field, thus increases ionization rate. movement main also...
Increasing the specific impulse has become one of main trends in development Hall thrusters and may be achieved by increasing proportion multiply charged ions plume. In this study, multiple ionization characteristics with large height–radius ratios their effects on other performance parameters were examined via numerical simulations. The simulation results show that a thruster ratio increases 7.8 percentage points, compared traditional thruster, can obtain higher average jet velocity under...
Abstract The accurate diagnosis of abnormal electron emission state in hollow cathodes is crucial for the stable operation Hall electric propulsion systems. In this study, a method reducing cathode working gas flow rate was used to simulate conditions which (CEES) deteriorating. By analyzing and comparing oscillation signals under steady-state conditions, it found that as CEES deteriorated, power content breathing decreased 1–40 kHz frequency band, main decreased; contrast, transit-time...
In this study, a 1.35 kW HEP-100X Hall thruster is used to explore effective methods for improving the global efficiency of across wide range flow rates, from perspective optimizing channel configuration. Experimental and simulation results indicate that an appropriate increase in length straight segment variable cross section can neutral gas density as well move high-gas-density zone toward outlet, thus increasing ionization rate moving main outward. At low rate, propellant utilization...
