چکیده
Shield crossing loess stratum will encounter many engineering problems such as excessive local soil deformation and ground collapse crater. Based on the phenomenon characteristics of caused by large-diameter shield strata, this paper summarizes curve, analyzes causes reaction deformation, main laws strata. And fuzzy mathematical method is used to analyze influencing factors provide theoretical support for subsequent numerical simulation objectives.

The trust value based on fuzzy comprehensive evaluation fluctuates remarkably. Aiming at this problem, this paper establishes membership function of trusted set, according to the trusted level in P2P trust model based on fuzzy comprehensive evaluation. The simulation results and analysis show that the membership function of trusted set can validate whether the trust evaluation value is sufficie...
متن کاملResearch on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
