	On hyperspectral remotely sensed image classification based on MNF and AdaBoosting (EI CONFERENCE) 会议论文 2012 3rd IEEE/IET International Conference on Audio, Language and Image Processing, ICALIP 2012, July 16, 2012 - July 18, 2012, Shanghai, China Xu Y.; Yu P.; Guo B.; Gao X.; Guo Y. 收藏 \| 浏览/下载：15/0 \| 提交时间：2013/03/25 As an effective statistical learning tool AdaBoosting has been widely used in the field of pattern recognition. In this paper a new method is proposed to improve the classification performance of hyperspectral images by combining the minimum noise fraction (MNF) and AdaBoosting. Because the hyperspectral imagery has many bands which have strong correlation and high redundancy the hyperspectral data are pre-processed by the minimum noise fraction to reduce the data's dimensionality whilst to remove noise bands simultaneously. Then we use an AdaBoost algorithm to conduct the classification of hyperspectral remotely sensed image. Experimental results show that the classification accuracy is improved and the time of calculation is reduced as well. 2012 IEEE.

	Study on time registration method for photoelectric theodolite data fusion (EI CONFERENCE) 会议论文 10th World Congress on Intelligent Control and Automation, WCICA 2012, July 6, 2012 - July 8, 2012, Beijing, China Yang H.-T.; Gao H.-B. 收藏 \| 浏览/下载：15/0 \| 提交时间：2013/03/25 In range measurement theodolite and radar constitute a real-time tracking system at different sites to track the same target in the air and get useful information exactly and timely. As the optical theodolite and radar have different sampling frequency and measurement system the data is sent to the fusion center is asynchronous. This paper proposed a time registration method based on multi-sensor data using Wavelet neural network algorithm which not only better solved the basic problems of theodolite fusion tracking but also improve the efficiency of data fusion. Simulation experiment and comparison with other time registration method have shown the advantage of this method. 2012 IEEE.

	Research on method of eliminating accurately mechanical resonance frequency of the theodolite by complex notch filter (EI CONFERENCE) 会议论文 2011 International Conference on System Science, Engineering Design and Manufacturing Informatization, ICSEM 2011, October 22, 2011 - October 23, 2011, Guiyang, China Cai L.-H.; Gao H.-B.; Zhang S.-M.; Ma Q.-K. 收藏 \| 浏览/下载：12/0 \| 提交时间：2013/03/25 In this paper We apply a complex notch filter to eliminate accurately influence of Mechanical resonance frequency on theodolite performance. By comparing magnitude-frequency characteristic of system and notch filter make two frequency characteristics counteract at the mechanical resonance frequency. Experiments show that the method can eliminate accurately mechanical resonance frequency and improve bandwidth and stability of the theodolite. 2011 IEEE.

We found the diffraction (002) peak at ~34.46 indicating that the ZnO thin films were C-oriented. ZnO films were highly transparent with a transmission ratio larger than 85% in the visible range. The surface morphology of the films was observed by atomic force microscopy (AFM). (2010) Trans Tech Publications.

We investigated the quality of the films by SIEMENS D8 X-ray diffractometer. The surface morphology of the films were observed by Digital Nanoscope IIIa AFM with normal silicon nitride tip in the contact mode. The hall effect measurements were carried out with indium ohmic contact. The transmission spectrum of the films were measured. The transmission ratio is larger than 80% in the region above the wavelength of 385nm and sharply decreased under 10% below the wavelength of 375 nm. (2010) Trans Tech Publications.
