| 1 | A Novel Multi-Hop Algorithm for Wireless Network with Unevenly Distributed Nodes显示文摘Node location estimation is not only the promise of the wireless network for target recognition,monitoring,tracking and many other applications,but also one of the hot topics in wireless network research.In this paper,the localization algorithm for wireless network with unevenly distributed nodes is discussed,and a novel multi-hop localization algorithm based on Elastic Net is proposed.The proposed approach is formulated as a regression problem,which is solved by Elastic Net.Unlike other previous localization approaches,the proposed approach overcomes the shortcomings of traditional approaches assume that nodes are distributed in regular areas without holes or obstacles,therefore has a strong adaptability to the complex deployment environment.The proposed approach consists of three steps:the data collection step,mapping model building step,and location estimation step.In the data collection step,training information among anchor nodes of the given network is collected.In mapping model building step,the mapping model among the hop-counts and the Euclidean distances between anchor nodes is constructed using Elastic Net.In location estimation step,each normal node finds its exact location in a distributed manner.Realistic scenario experiments and simulation experiments do exhibit the excellent and robust location estimation performance. | Yu Liu Zhong Yang Xiaoyong Yan Guangchi Liu Bo Hu | 2019 | Computers, Materials & Continua2019，，1： | 0 |
| 2 | Prospective and Practical Significance of Virtual Autopsy Laboratory显示文摘The virtual anatomy laboratory was jointly established by the Jilin Province Department of Public Security,Public Security Bureau of Changchun,Jilin University and Neusoft Medical Systems Co.,Ltd.on December 30,2019.Details of the laboratory construction,virtual autopsy process,case analysis,research and development,establishment of standards,application in teaching,and other aspects of the center are summarized in this paper.In addition,we expound the prospective and practical significance of the virtual anatomy laboratory.Based on computed tomography and magnetic resonance detection methods,the prospective applications of virtual anatomy in forensic identification are explored through the analyses of two real-life cases.Using information from traditional anatomy as the gold standard,this study expanded on and explored the application technology and scenarios of virtual anatomy in imaging,clinical diagnosis,and equipment manufacturing,among other fields.The four cooperating units have their strengths and will yield valuable scientific research results and social benefits. | Yimeng Wang Zhiming Chen Gang Liu Wanan Zhu Wenxin Wang Dandan Zhou Weilong Chen Yanbin Gao Jun Yang Feng Huang Huimao Zhang Guangchi Yu Lijun Wang | 2021 | Journal of Forensic Science and Medicine2021，7，1： | 0 |
