The observer estimates the drag  the drag rate and the perturbation due to model uncertainty and disturbance for drag tracking. Mars entry simulation was performed to assess the performance of the adaptive guidance law. The results demonstrate that the proposed guidance law is robust to model error  and can recover the ideal performance of the feedback linearization control.

In order to improve the surface precision of membrane reflectors  the formation and surface shape error of a membrane at uniform load are studied based on the henky-cambell equations of circular membrane. The ANSYS software is used to build an optimization model of membrane reflector surface shape  in which the yield strength is the state variable  the surface load on ten concentric annular regions of the mirror is the design variable  and the minimum RMS between ideal surface and mirror surface is the target function. and the theoretical and experimental result show that RMS and PV of the optimized surfaces are reduced respectively than those before optimization. In a word  this paper offers the theoretical and experimental basis of the polyimide membrane reflector. 2011 IEEE.   A Cluster-Resonance Criterion for Al-TM Quasicrystal Compositions 期刊论文  OAI收割 Israel Journal of Chemistry, 2011, 卷号: 51, 期号: 11-12, 页码: 1226-1234 H.

This article researches extraction arithmetic for missile bullet' multiple targets. Above all  enactment threshold of area  acquire middle axes of target by adopting Hough transforming and approximating and calculate obliquity angles of targets. In course of matching  accomplish missile bullet's multiple targets data association of serial images by making use of improving eigenfunction and achieve extraction of missile bullet's multiple targets after obtaining center position of targets  adopting OSTU method change numeral image into binary image  according to area of target  forecast searching region of target matching by using Kalman filter  area of targets  and abstract separately center position of targets and area of targets  judge conglutination and obstruct  then separate targets in term of wave crest and trough's variety of grey histogram of conglutination region  grey average of target and obliquity angles of targets. The experimental result shows that right ratio of the extraction targets reach to 90%. The article use correct mathematical model and reasonable arithmetic and obtain effectively parameter of missile bullet' multiple targets. 2010 IEEE.  at the same time  obtain grey average of target  mark target region   a general compiler for password-authenticated group key exchange protocol 期刊论文  OAI收割 INFORMATION PROCESSING LETTERS, 2010, 卷号: 110, 期号: 4, 页码: 160-167 Li Hui; Wu Chuan-Kun; Sun Jun   |  收藏  |  浏览/下载：12/0  |  提交时间：2011/05/24 Cryptography  Password  Group key exchange  Random-oracle model  Ideal-cipher model   Analysis and modelling of no-reference video quality assessment (EI CONFERENCE) 会议论文  OAI收割 2009 International Conference on Computer and Automation Engineering, ICCAE 2009, March 8, 2009 - March 10, 2009, Bangkok, Thailand Tian Y.; Zhu M. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 Video processing system may introduce some amounts of distortions in the video signal. It is crucial to measure the video quality blindly for most image processing applications which could not obtain the original image. Different Video Quality Assessment (VQA) methods are analysis in this paper. A state of art in the field of No- Reference (NR) VQA is presented. Finally  an ideal NR VQA model is proposed. 2009 IEEE.
