With the rapid development of civil aviation, air traffic management system plays a more important role in ensuring aviation safety, and hence there is an urgent need to use information technology to improve analysis level and efficiency of aviation safety information. In this paper, an air traffic management safety database analysis system is developed. It can not only store basic information of safety events by entering data directly or acquiring data from other sources, but also quantify and classify the incidents according to human factor analysis, defense failure analysis and organization factor analysis of SHELL model so as to achieve in-depth analysis of the safety information. In the development of the system, B/S mode, MySQL database, Java language and Struts 2 + Spring + Hibernate framework are adopted. Via flexible user role and permission mechanism it could ensure a safe and ordered access to safety data. Moreover, considering importance and complexity of data acquisition, this module is deployed on cloud computing platform as a service, which could improve data acquiring efficiency and also lay a foundation for follow-up data mining of ATC safety data. The system could provide a quantitative decision support for ATC safety information management.

The spatial panel data model is commonly used in practice. In order to explore the property of the parameter estimator for the spatial error panel data model with fixed effects, the quasi-maximum likelihood estimator for the model is provided in this paper. And two theorems on the asymptotic properties of the estimator are proposed and proved. For illustration, the associated simulation is employed to verify the effectiveness of the proposed strategies. Empirical results show that when the number of the spatial units is large and the number of the time series is finite, the estimator is consistent and asymptotically normal. In conclusion, it is an estimator with good performance.

In order to efficiently solve the unconstrained optimization problem in which the objective function is very nonlinear, an innovative framework of optimization which is different from line search framework is proposed in this paper. This new method determines the step-length first with nonmonotone line search technique, and generates a two dimensional subspace spanned by the steepest-descent direction and an auxiliary vector. In this subspace, a circle with the current point as its center and with step-length as it radius is constructed. On this circle, the minimizer of the objective function as the next iterative point can be calculated with arc search, and the search direction can be generated with the minimizer and the current point. The variation of gradient of the objective function in the search direction is used for determining the step-length of the next step. The global convergence of this new algorithm is proved in this paper under some mild assumptions. Numerical tests illustrate that this new algorithm is more efficient than conjugate gradient direction. The arc search improves the efficiency of the iterative process. This new algorithm requires only the storage of three vectors such that it is suitable for large scale problems.

According to the issues encountered by traditional web chart technologies, the paper, following the boom of HTML5, did a research into web mapping of vector nautical charts based on HTML5. The research mainly includes: 1) System architecture for the HTML5 based web chart application, in which HTML5, CSS and Javascript are used to build and style the client Web chart pages, and Node. Js is used to construct the server-side to provide both HTTP and Web Socket services, 2) Organization of vector chart data to obtain more efficiency of data network transmission and data procession, for which original S-57 charts are converted into Shape files and a Javascript framework is designed to read and parse the Shape files for the client, 3) Vector nautical charts display on Web page, for which a Javascript display framework and rendering functions for chart points, lines and areas symbols are designed based on HTML5 Canvas. An application of web chart based vessel tracking is tested further to verify the proposed methods. The results showed that HTML5 is suitable to develop web vector chart applications, although there are several problems waiting to be solved such as it can't comply with S-52 display standard completely.

Currently, the LXI data acquisition system often requires high speed, large capacity memory, but the internal storage resource of FPGA is not sufficient to meet the requirements. In order to solve above problems, a SDRAM controller is proposed in this paper, where the Multiple FIFO based on the on-chip resources of FPGA serves as the read and write cache to realize the multiple functional modules performing the read/write operation in LXI acquisition system by the design of priority algorithm and reasonable controlling the access of SDRAM from external device. At the same time, the SDRAM can still communicate at high frequency by the suitable time limitation. The simulation results show that the proposed SDRAM controller can not only realize reading and writing data, but also its operating frequency is able to meet the requirements of functional modules.
