The mathematical model of Linear double inverted pendulum has been studied and estabLished with dynamics analytical method and LQR theory is used to design the optimal Linear inverted pendulum controller  then  the integration technology is used to design the variable parameters self-tuning fuzzy controller. Thereby  the fuzzy controller input variable dimension and the number of fuzzy control rules have been extremely reduced. Two controllers are designed for inverted pendulum system control and the comparison simulation experiments have been done. The results show that the controllers can both reaLize good control  and the fuzzy controller has higher precision  faster response  better stabiLity and robustness. 2011 IEEE.   The new approach for infrared target tracking based on the particle filter algorithm (EI CONFERENCE) 会议论文  OAI收割 International Symposium on Photoelectronic Detection and Imaging 2011: Advances in Infrared Imaging and Applications, May 24, 2011 - May 24, 2011, Beijing, China 作者:  Sun H.;  Han H.-X.;  Sun H. 收藏  |  浏览/下载：63/0  |  提交时间：2013/03/25 Target tracking on the complex background in the infrared image sequence is hot research field. It provides the important basis in some fields such as video monitoring  precision  and video compression human-computer interaction. As a typical algorithms in the target tracking framework based on filtering and data connection  the particle filter with non-parameter estimation characteristic have ability to deal with nonlinear and non-Gaussian problems so it were widely used. There are various forms of density in the particle filter algorithm to make it valid when target occlusion occurred or recover tracking back from failure in track procedure  but in order to capture the change of the state space  it need a certain amount of particles to ensure samples is enough  and this number will increase in accompany with dimension and increase exponentially  this led to the increased amount of calculation is presented. In this paper particle filter algorithm and the Mean shift will be combined. Aiming at deficiencies of the classic mean shift Tracking algorithm easily trapped into local minima and Unable to get global optimal under the complex background. From these two perspectives that "adaptive multiple information fusion" and "with particle filter framework combining"  we expand the classic Mean Shift tracking framework.Based on the previous perspective  we proposed an improved Mean Shift infrared target tracking algorithm based on multiple information fusion. In the analysis of the infrared characteristics of target basis  Algorithm firstly extracted target gray and edge character and Proposed to guide the above two characteristics by the moving of the target information thus we can get new sports guide grayscale characteristics and motion guide border feature. Then proposes a new adaptive fusion mechanism  used these two new information adaptive to integrate into the Mean Shift tracking framework. Finally we designed a kind of automatic target model updating strategy to further improve tracking performance. Experimental results show that this algorithm can compensate shortcoming of the particle filter has too much computation  and can effectively overcome the fault that mean shift is easy to fall into local extreme value instead of global maximum value.Last because of the gray and fusion target motion information  this approach also inhibit interference from the background  ultimately improve the stability and the real-time of the target track. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   Principles and methods for the validation of quantitative remote sensing products SCI/SSCI论文  OAI收割 2010 作者:  Tian J. 收藏  |  浏览/下载：32/0  |  提交时间：2012/06/08 quantitative remote sensing productions (QRSPs)  validation  eigenaccuracy  eigenhomogeneity  scale-free phenomenon  information  fractal dimension  scaling  regional-distribution  model  emissivity  scale  flux   Oasis landscape change and spatial character analysis in the tarim river origin basin 会议论文  OAI收割 Proceedings - 2009 International Conference on Environmental Science and Information Application Technology, ESIAT, Wuhan, China, 2009 Yan; Dou1; Xi; Chen1 收藏  |  浏览/下载：61/0  |  提交时间：2011/08/23 Environmental engineering - Forestry - Fractal dimension - Geographic information systems - Land use - Rapid solidification - Water supply - GIS - Hotan oasis - LUCC - RS - Spatial character   The study on landscape pattern change of wetland based on GIS and RS: An example of Dongting Lake area 会议论文  OAI收割 ., 2008-06-28 Liang,Shou-Zhen   |  收藏  |  浏览/下载：28/0  |  提交时间：2011/07/22 EcoSystems - Fractal Dimension - Geographic Information Systems - Geomorphology - Lakes - Rapid Solidification - Remote Sensing   Spatial pattern analysis of land cover change trajectories in Tarim Basin, northwest China EI期刊论文  OAI收割 2008 作者:  Li Baolin 收藏  |  浏览/下载：28/0  |  提交时间：2012/06/11 Agglomeration  Arid regions  Classification (of information)  Forestry  Fractal dimension  Surface water resources  Trajectories   Dynamic change analyses on the land use/land cover in arid areas of northwest China with RS and GIS: The case of Liangzhou County in Wuwei City 会议论文  OAI收割 International Conference on Earth Observation Data Processing and Analysis, ICEODPA,, Wuhan, China, December 28, 2008 - December 30,2008 Liu, Fang; Zhang, Zengxiang; Tan, Wenbin; Dong, Tingting; Wei, Xianhu 收藏  |  浏览/下载：23/0  |  提交时间：2014/12/07 Land use  Arid regions  Data processing  Drought  Economics  Forestry  Fractal dimension  Geographic information systems  Landforms  Observatories  Partial discharges  Rapid solidification  Remote sensing  Transfer matrix method   Spatial and temporal dynamic of Urban sprawl in west China: A case study of Chongqing, China 会议论文  OAI收割 Geoinformatics 2008 and Joint Conference on GIS and Built Environment: Geo-Simulation and Virtual GIS Environments, Guangzhou, China, June 28, 2008 - June 29,2008 Fengyun, Mu; Zengxiang, Zhang; Bin, Liu; Lijun, Zuo 收藏  |  浏览/下载：26/0  |  提交时间：2014/12/07 Virtual reality  Fractal dimension  Geographic information systems  Land use  Morphology  Rural areas  Urban planning   Asymmetry of prefrontal cortical convolution complexity in males with attention-deficit/hyperactivity disorder using fractal information dimension 期刊论文  OAI收割 BRAIN & DEVELOPMENT, 2007, 卷号: 29, 期号: 10, 页码: 649-655 作者:  Li, Xiaobo;  Jiang, Jiefeng;  Zhu, Wanlin;  Yu, Chunshui;  Sui, Manqiu 收藏  |  浏览/下载：31/0  |  提交时间：2015/11/08 anatomic MRI  asymmetry pattern  attention-deficit hyperactivity disorder  cortical convolution complexity  information dimension  prefrontal cortex
