    Target sampling based on routing behavior analysis in network topology measurement by ZHANG Yu, FANG Bin-xing, ZHANG Hong-li

    Published 2009-01-01
    “…In order to investigate the insufficiency of target sampling in current network topology measurement practice and the distortion of measurement models,a sort of target sampling methods based on routing behavior analysis were pre-sented,namely,the uniform random sampling as a benchmark method,the minimum cover sampling as an optimal method,the last-hop sampling for the path diversity,and the bisection sampling for the destination prefix diversity.Ex-periments based on real measurement data show that a half of topology information can be missed in the traditional ‘1 per /24’ random sampling,of which 10% of missed information is caused by the path diversity and the rest is caused by des-tination prefix diversity.The minimum cover sampling is robust to the routing dynamics and performs better than the uniform random sampling at the long-term practice.…”

    Multiple-Image Encryption Based on Compressive Ghost Imaging and Coordinate Sampling by Xianye Li, Xiangfeng Meng, Xiulun Yang, Yongkai Yin, Yurong Wang, Xiang Peng, Wenqi He, Guoyan Dong, Hongyi Chen

    Published 2016-01-01
    “…A multiple-image encryption method that is based on a modified logistic map algorithm, compressive ghost imaging, and coordinate sampling is proposed. In the encryption process, random phase-only masks are first generated with the modified logistic map algorithm; multiple secret images are transformed to be sparsed by the 2-D discrete cosine transformation (DCT) operation and scrambled by different random sequences; the scrambled images are then grouped to one combined image with the help of the coordinate sampling matrices; finally, putting the combined image in the object plane of the compressive ghost imaging system, the ciphertext will be obtained from the buck detector and transferred to the receivers. …”

    Region sampling NeRF-SLAM based on Kolmogorov-Arnold network. by Zhanrong Li, Jiajie Han, Chao Jiang, Haosheng Su

    Published 2025-01-01
    “…Inspired by the quadtree in ORB-SLAM2 and the recently proposed Kolmogorov-Arnold network, our approach replaces the MLP with a KAN network based on Gaussian functions, combines quadtree-based regional pixel sampling and random sampling, delineates the scene by voxels, and supports dynamic scaling to realize a high-fidelity reconstruction of large scenes for a SLAM system. …”

    Sampling plan for using a motorized penetrometer in soil compaction evaluation by Lindolfo Storck, Sarha G. K. Kobata, Betania Brum, André B. Soares, Alcir J. Modolo, Tangriani S. Assmann

    Published 2016-03-01
    “…To estimate the mean of resistance to penetration, 12 blocks of four points per experimental plot should be used for a semi-amplitude of the confidence interval equal to 10% of the mean (1 - p = 0.95). Twenty random points may be sampled to estimate mean of penetration resistance for a semiamplitude confidence interval of 10% of the man (1 - p = 0.95). …”
