The composite skin coating structure of the front edge supersonic aircraft body is deformed, cracked and even stripped due to continuous impact raindrops. material used in this paper based on carbon fiber T300 braided material, its surface coated with three different types coatings.In order reveal rain erosion damage mechanism establish criterion, a multi-jet test device rotating arm are carry out tests materials, respectively, simulate droplet at same position real field impact. behavior...
Abstract The presence of minute particles suspended in the air poses a significant threat to aircraft and wind turbine, subjecting them solid particle impact wear. This exposure can culminate delamination failure protective structural coatings, impeding longevity efficacy these structures. To delve into intricate behavior erosion on skin unravel their underlying damage mechanisms, establish definitive criterion for assessing coating damage, we employed carbon fiber T300 as substrate, applied...
Single-pixel compressive imaging can recover images from fewer measurements, offering many benefits especially for the modalities where array detection is unavailable. However, widely used random projections fail to explore internal relations between coding patterns and image reconstruction. Here, we propose a single-pixel method based on deterministic origami pattern construction that lead more accurate ordering sequence better quality. It decrease sampling ratio, closer upper bounds. The...
Convolutional neural networks (CNNs) and transformers have boosted the rapid growth of object detection in synthetic aperture radar (SAR) images. However, it is still a challenging task because SAR images usually characteristics unclear contour, sidelobe interference, speckle noise, multiple scales, complex inshore background, etc. More effective feature extraction by backbone augmentation neck will bring promising performance increment. In response, we make full use advantage CNNs...
A new polarimetric synthetic aperture radar (SAR) images classification method based on residual network (ResNet) and deep autoencoder (DAE) is proposed in this letter. The patch-based pixel-based are well integrated to achieve better accuracy clearer contour features. results with ResNet DAE obtained respectively. According the results, a hybrid combining developed determine category label of each pixel. attractive feature combined take full use polarization scattering characteristics pixel...
When minimum shift keying (MSK)'s carrier is changed as the linear frequency modulation (LFM) signal, it called MSK-LFM for short. It a new type of radar-communication multifunctional integrated waveform. Under assumption that bandwidth radar receiver equal to LFM energy leakage analysed. The trade-off between number modulated bits and derived analytically. equation demonstrates relationship detection performance digital communication MSK-LFM, which also gives principle designing To better...
Transarterial chemoembolization (TACE) has been widely used for hepatocellular carcinoma. Reducing hypoxia in the tumor microenvironment after TACE remains a challenge as progression is common post-TACE patients due to hypoxic microenvironment. In this study, melatonin loaded on p(N-isopropyl-acrylamide-co-butyl methylacrylate) (PIB-M) was embolism. Two types of human hepatoma cell lines were explore mechanism by which prevents growth and metastasis cancer cells vitro. A VX2 rabbit model...
Changsha City is the political, economic and cultural centre of Hunan Province. In recent years, because large-scale urban construction special geological structure, land subsidence has become one main disasters in City, which seriously threatens health buildings infrastructure. To solve this problem, paper monitored from 2015 to 2021 using Point Target (PT) based Small Baseline Subset InSAR (SBAS-InSAR), revealed spatial distribution characteristics study area, studied causes subsidence,...
In this work, we demonstrated a new type of biomimetic multispectral curved compound eye camera (BM3C) inspired by insect eyes for aerial imaging in large field view. The proposed system exhibits maximum view (FOV) 120 degrees and seven-waveband images ranging from visible to near-infrared wavelengths. Pinhole theory the image registration method feature detection are used reconstruct 3D data cube. An airborne experiment is performed assembling BM3C on an unmanned vehicle (UAV). As result,...
Reconfigurable intelligent surface (RIS) technology is a promising solution to improve the performance of existing wireless communications. To achieve its cost-effectiveness advantage, there inevitably exist certain hardware impairments in system. Therefore, it more reasonable design passive beamforming this scenario. Some research has considered such problems under transceiver impairments. However, their still leaves room for improvement, possibly due algorithms not properly handling...
A modified Fourier–Ritz method is developed for the flexural and in‐plane vibration analysis of plates with two rectangular cutouts arbitrary boundary conditions, aiming to provide a unified solving process cases that plate has various locations or sizes cutout, different kinds conditions. Under current framework, modifying position cutout conditions just as changing geometric parameters plate, there no need change solution procedures. The can be obtained by setting stiffness constant...
