Long-term exposure to high concentrations of fine particles can cause irreversible damage people’s health. Therefore, it is extreme significance conduct large-scale continuous spatial particulate matter (PM2.5) concentration prediction for air pollution prevention and control in China. The distribution PM2.5 ground monitoring stations China uneven with a larger number southeastern China, while the sites also insufficient quality control. Remote sensing technology obtain information quickly...
A novel advanced oxidation process (AOP) using ultraviolet/sodium chlorite (UV/NaClO2) is developed for simultaneous removal of SO2 and NO. NH4OH, as an additive, was used to inhibit the generation ClO2 NO2. The efficiencies NO reached 98.7 99.1%. enhanced by greater UV light intensity shorter wavelengths but insensitive changes in pH temperature. at 500–1000 mg/m3 improved removal, especially absence UV. coexistence O2 facilitated ClO2–. HCO3–, Cl–, Br– their roles were negligible when...
A rapid method is developed for fabricating low-cost and high-numerical-aperture photosensitive-gel microlens arrays (MLAs) with well-controlled curvatures. An UV-curable film beneath the microholes of a silicon mold can be flexibly deformed by thermally manipulating surface tension photosensitive gel pressure difference across air-photosensitive-gel interface. The concave interface then solidified through UV curing, forming MLA curvature. MLAs focal length ranging from 51.4 to 71.9 μm...
A straightforward technique for fabricating low-cost microlens arrays with controllable focal length is developed. By harnessing and manipulating the interfacial energy between liquid-state acrylate resin solidified polydimethylsiloxane (PDMS), surface of in PDMS microhole presents a spherical shape curvature can be flexibly controlled. With change processing time modification microholes, concave microlenses varies from -296.3 μm to -67.4 μm. The numerical aperture 0.45 realized. are also...
The Central and West Asia Economic Corridor (CWAEC) is a critical component of the Belt Road Initiative (BRI), that vegetation changes in region are under significant uncertainty due to fragile ecological conditions, diverse climatic variability, these uncertainties compounded by interaction natural factors human activities. For sustainable development CWAEC, it urgent pay attention its regional environmental health. Using MOD13A3 NDVI data ERA5 meteorological reanalysis data, this study...
With the increasing communication and storage of point cloud data, there is an urgent need for effective objective method to measure quality before after processing. To address this difficulty, we propose a projection-based blind indicator via multimodal learning which can perceive both geometric distortion texture by using four homogeneous modalities (i.e., texture, normal, depth roughness). fully exploit information, further develop deformable convolutionbased alignment module graph-based...
In this paper, the impact of successive double droplets on a super-hydrophobic tube surface is numerically studied using three-dimensional model by coupled level set and volume fluid method. The effect velocity under different curvature ratios studied. With increase in velocity, two kinds models (out-of-phase in-phase impact) are obtained, coalescent liquid film presents rebound, breakup-rebound, splash-rebound. ratio, spread along circumferential direction promoted, rim leading up-warp can...
On the basis of ghost imaging, this paper proposes a multiple-image encryption scheme combining public key cryptography and Hadamard pattern. In system, plurality light paths are set, patterns used for illumination, so that each path is concentrated in bucket detector to obtain intensity values all images. Then, detected encrypted by using algorithm final ciphertext. The use allows high-quality reconstruction. addition, randomness permutation operation provide strong security feature system....
Images are one of the important sources getting information, and process images can be affected by various factors. Atmospheric turbulence is them. Ghost imaging has a positive effect on suppressing atmospheric turbulence, but its reconstruction results not stable, it cannot get high-quality under extreme conditions. In this paper, we simulate using phase screen, combine computational ghost to process, analyze factors that affect imaging. We use an end-to-end neural network input bucket...

These processes present spread, retract, rebound, breakup splash. out-of-phase takes place with 1.25 m/s, while in-phase 1.44 With larger than liquid crown presents deforms after trailing droplet impact, then it would gather at film edge, rebound or break up. When velocities range 1.5 finger before appearing. head...
Abstract The effect of surface wettability on droplet impact spherical surfaces is studied with the CLSVOF method. When velocity constant, increase in contact angle (CA), maximum spreading factor and time needed to reach (tmax) both decrease; liquid film more prone breakup rebound. CA increasing, increases while tmax decreases. With curvature ratio when between 30 150°, it decreases ranges from 0 30°.
