Ensuring scheduled flight security and punctual is a basic requirement of civil aviation.
Introduction: Air travel has increased considerably in recent years, the number of passengers of China civil aviation has brokenthrough 260 million, China has become second air transport power country because of the increace of passenger flow, To guarantee scheduled flight safe and punctual is the basic requirement of civil aviation transportation.passengers often strand for a long time in security area and check-in area.
It is easy to trigger group events and bring a lot of negative effects to civil aviation transportation.
Shangyao Yan, Ching-Hui Tang in Department of Civil Engineering, National Central University do some research in heuristic approach for airport gate assignments for stochastic flight delays.

Studies on Dynamic Characteristics of a Typical Model of Asymmetric Continuous Rigid-Frame Bridge under Different Ratio of Middle Span to Side Span Tian Liang1, Jun Dong1, a and Xuejian XIANG2 1School of Civil Engineering and Traffic Engineering, Beijing University of Civil Engineering and Architecture, Beijing, 100044, China 2 Research Institute of Highway, Ministry of Communication, Beijing, 100088, China ajdongcg@bucea.edu.cn Keywords: Asymmetric continuous rigid-frame bridge, Ratio of middle span to side span, Seismic response, Dynamic characteristics Abstract.
Based on the engineering background of Sinan Yantou river Bridge in Guizhou province, dynamic characteristics of the type of bridge are studied in this paper.
Firstly, by using Midas/Civil, 6 different models are established and their modal analysis could be done while it is considered that the beam of left T-shaped is gradually decreasing under the same height of piers.

Introduction The concrete-filled steel tube (CFST) was used in civil engineering since more than 100 years.
With a widely application in civil engineering, the investigation of FCC developed rapidly in last decades.
This new structure named FSCC which has favorable performance is of a good application prospects in civil engineering.

This type of waste, which may contain cellulose, was found to be adequate for addition to cement-based products in civil construction [3,4].
These samples were sent to the Laboratory of Civil Engineering (LECIV) at the State University of the Northern Rio de Janeiro (UENF) in Campos dos Goytacazes, identified as a star in Fig. 1.

The Electronic Flight Bag Based On Mobile Terminal Guishu Xia1,a , Jing Lu2, b and Yuanqing He 2,c 1 Aviation Engineering Institute, Civil Aviation Flight University of China, Guanghan Sichuan, China 2 Institute of Computer Science Technology, Civil Aviation Flight University of China, Guanghan Sichuan, China a xgs922@163.com, bmaoyanqq@163.com, chcaac@163.com, Keywords: The electronic flight bag, mobile terminal, iOS, interactive Abstract.
The electronic flight bag in China with few products owning Chinese independent intellectual property is attracting increasing attention in the field of the civil aviation industry in recent years.
The UI design based on the main color of the Civil Aviation Authority of the relevant laws and regulations as well as pilot human factors research conclusions shown in Table 1.
And China's civil aviation industry imports mature foreign products, with the advent of fully independent intellectual property products rarely.
