Displacement measurement is an essential method for structural safety assessment and health monitoring, the static dynamic characteristics of structure can be obtained through displacement. In order to overcome limitations sensors in vibration large structures, as well poor adaptability visual algorithms such machine learning digital image processing, this paper takes bridge research object introduces deep into field measurement. Moreover, based on convolutional neural network, a new...
On the basis of gray edge hypothesis, further considering influence image information and high frequency noise on light color estimation, a constancy calculation method based algorithm is proposed. In this paper, Shi-gehler data set used, because card in original will affect correction, so black, making experimental results more accurate. order to ensure suppression high-frequency noise, Gaussian filter replaced by bilateral estimate illumination chroma, von kries diagonal transformation...
Utilizing a sample of 3,211 Chinese listed firm-years during COVID-19 crisis, this paper empirically tests the industry peer effect charity giving. Our empirical results show that higher amount donation at level significantly promotes firm's potential and magnitude Besides, SOEs react more actively to philanthropy other in same industry, while privately controlled firms tend follow donating decisions made by politically connected peers. Finally, above relation is pronounced when competition...
Firstly, this article focous on the requirements for RFID antenna of ecommerce--a fractal design folded dipole by moment method simulation analysis designed antenna, return loss performance are calculated. In order to have more redundancy antennas in actual use when all kinds bad environment function properly, we try methods additional passive patch, microcosmic structure and mirror compensation improve antenna. Then compare effects multiple improvement methods, find best optimization...
In order to solve the problem of error and abstract in identification process caused by current wavelet methods using grayscale identify noise sources, a cabin source method based on transform(WT) was proposed. Firstly, multi-wavelet reconstruction signals were constructed from original time-domain through Matlab Wavelet Toolbox. Secondly, eigenvectors defined calculating energy value reconstructed at all levels. And correlation coefficients between signal other obtained these eigenvectors....
