    Survey on the deployment and design for regular topology structures in wireless sensor networks by Wen-xiang LI, Ya-jie MA, Jun XU, Jian-feng YANG

    Published 2012-11-01
    “…In wireless sensor networks,such regular topology structures as Square,Hexagon and Triangle could fully cover the area to be monitored,provide accurate positioning for special events,and achieve better network performance.In order to provide valuable guidelines for WSN design and optimization,related works on regular topology structures was surveyed.By the analysis on the index of Area per Node,the deployment method and efficiency of regular topology structures under such cases as full coverage,k-coverage and l-connectivity was explored.the performance,variation and application scenarios in such aspects as network connectivity,energy consumption,transmission performance,routing scheme and MAC protocol was summarized.The optimal application conditions for each structure together with several directions for further research were proposed.…”

    Example of Structure Modeling and Analysis of Ultrasound Scattering for Trabecular Bone by Janusz WÓJCIK, Jerzy LITNIEWSKI, Andrzej NOWICKI

    Published 2013-11-01
    “…A trabecular bone consists of trabeculae whose mechanical properties differ significantly from the surrounding marrow, therefore an ultrasonic wave propagating within the bone structure is strongly scattered. The aim of this paper was to evaluate the contribution of the first, second and higher order scattering (multiple scattering) into the total scattering of ultrasound in a trabecular bone. …”
