The calculation results and evaluation In order to ensure the safety of subway operation, the deformation of tunnel engineering requirement is very strict on the engineering, the permissible value of tunnel deformation and the diameter of the tunnel, the construction of the shield lining segments and segment between the combination are closely related, but so far there has not yet been unified recognized allowable deformation value of the metro tunnel in engineering.

Optimum Design of the Cooperation Objective for Computer Vision-based UAV autonomous Landing Dongwu Feng, Guili Xu*a, Biao Wang, Yupeng Tian, Yongqiang Ye College of Automation Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing, Jiangsu 210016, China aguilixu@nuaa.edu.cn Keywords: Autonomous landing; Computer vision; Infrared; Blurring Abstract.In this paper, a novel approach to improve the infrared cooperative object for accurately landing is proposed.
Simulation Fig. 4 "T"-shaped cooperative target model Fig.4 shows the original "T"-shaped co-operation target model, the surface material is mainly an iron covered by an increase infrared radiation coating, of which infrared emission coating was 0.94.
It is evidenced in the Fig.10 that since the new cooperation target is changed with material, shape and other factors, the blurring edge is reduced compared with the old one.

Introduction Discovered in 1991 by Iijima [1] carbon nanotubes (CNTs) are being globally as a new dream materials in the 21st century due to their extraordinary mechanical and unique electronic properties and broadening their applications to almost all the scientific areas.
In addition to bulk synthesis and reproducible device production, controlled positioning of CNTs on a substrate without any postsynthesis methods has been considered as a key role of applications to field emission transistors [2], chemical sensors [3], optical devices for telecommunications [4] and etc.
Also, the author would like to acknowledge the feedback received from reviewers and those authors that attended the 2010 IEEE International Conference on Nanotechnology and Biosensors, Hong Kong, where this material was initially presented.
