We detect optical Quasi-Periodic Oscillations (QPOs) that move to higher frequencies as the outburst progresses, tracking both the frequency and evolution of similar X-ray QPOs previously reported. Correlated X-ray/optical data reveal a complex pattern of lags, including an anti-correlation and a sub-second lag that evolve over the first few weeks of outburst. They also show correlated components separated by a lag equal to the QPO period roughly centered on zero lag, implying that the inter-band variability is strongly and consistently affected by these QPOs at a constant phase lag of roughly ±Ю The synchronisation of X-ray and optical QPOs indicates that they must be produced in regions physically very close to each other  we thus propose that they can be explained by a precessing jet model, based on analogies with V404 Cyg and MAXI J1348-630.   Fixed-time observer based adaptive neural network time-varying formation tracking control for multi-agent systems via minimal learning parameter approach 期刊论文  OAI收割 IET CONTROL THEORY AND APPLICATIONS, 2020, 卷号: 14, 期号: 9, 页码: 1147-1157 作者:  Xiong, Tianyi;  Pu, Zhiqiang;  Yi, Jianqiang;  Tao, Xinlong   |  收藏  |  浏览/下载：52/0  |  提交时间：2020/07/06 neurocontrollers  multi-agent systems  Lyapunov methods  closed loop systems  nonlinear control systems  time-varying systems  adaptive control  observers  uncertain systems  position control  radial basis function networks  robust control  control system synthesis  learning (artificial intelligence)  minimal learning-parameter approach  fixed-time CLSO  time-varying formation tracking problem  formation tracking control scheme  multiagent systems  time-varying formation tracking control problem  model uncertainties  velocity measurements  radial basis function neural networks  fixed-time cascaded leader state observer  fixed-time observer-based adaptive neural network time-varying formation tracking control  RBFNN-based adaptive control scheme   Trajectory Planning Approach to Output Tracking for a 1-D Wave Equation 期刊论文  OAI收割 IEEE TRANSACTIONS ON AUTOMATIC CONTROL, 2020, 卷号: 65, 期号: 5, 页码: 1841-1854 作者:  Feng, Hongyinping;  Guo, Bao-Zhu;  Wu, Xiao-Hui   |  收藏  |  浏览/下载：22/0  |  提交时间：2020/06/30 Propagation  Observers  Trajectory  Planning  Mathematical model  Measurement uncertainty  Payloads  Error-based feedback  noncollocated configuration  observer  output tracking  wave equation   Robust tracking based on local structural cell graph 期刊论文  OAI收割 JOURNAL OF VISUAL COMMUNICATION AND IMAGE REPRESENTATION, 2015, 卷号: 31 作者:  Fan, Heng;  Xiang, Jinhai;  Liao, Honghong;  Du, Xiaoping 收藏  |  浏览/下载：26/0  |  提交时间：2016/04/20 Visual tracking  Local structural cell (LSC)  Local structural cell graph (LSCG)  Bayesian framework  Graph matching  Superpixel  Local based representation  Appearance model   A visual measurement of fish locomotion based on deformable models 会议论文  OAI收割 7th International Conference on Intelligent Robotics and Applications (ICIRA), Guangzhou, PEOPLES R CHINA, DEC 17-20, 2014 作者:  Xia, Chunlei(1,2);  Li, Yan;  Lee, Jang-Myung;  Xia, Chunlei 收藏  |  浏览/下载：24/0  |  提交时间：2015/08/10 Fish  Active Shape Models  Biological studies  Deformable models  Model-based tracking  Observation systems  Posture measurement  Swimming mode  Visual measurements   A visual measurement of fish locomotion based on deformable models 会议论文  OAI收割 The 7th International Conference on Intelligent Robotics and Application (ICIRA2014), Guangzhou, China, December 17-20, 2014. 作者:  Xia, Chunlei;  Li Y(李岩);  Lee, Jang-Myung 收藏  |  浏览/下载：39/0  |  提交时间：2014/12/29 Fish Tracking  Model based Tracking  Active Shape Model  Posture Measurement  Swimming Modes   Active Contour-Based Visual Tracking by Integrating Colors, Shapes, and Motions 期刊论文  OAI收割 IEEE TRANSACTIONS ON IMAGE PROCESSING, 2013, 卷号: 22, 期号: 5, 页码: 1778-1792 作者:  Hu, Weiming;  Zhou, Xue;  Li, Wei;  Luo, Wenhan;  Zhang, Xiaoqin 收藏  |  浏览/下载：40/0  |  提交时间：2015/08/12 Abrupt motion  active contour-based tracking  adaptive shape model  dynamic shape model   From quality to quantity: The role of common features in consumer preference 期刊论文  OAI收割 JOURNAL OF ECONOMIC PSYCHOLOGY, 2012, 卷号: 33, 期号: 6, 页码: 1043-1058 作者:  Su, Yin;  Rao, Li-Lin;  Li, Xingshan;  Wang, Yong;  Li, Shu 收藏  |  浏览/下载：42/0  |  提交时间：2015/08/24 Common features  Cancellation-and-focus model  Equate-to-differentiate approach  Eye-tracking  Attribute-based strategies   移动摄像机下目标的轮廓与区域跟踪 学位论文  OAI收割 工学博士, 中国科学院自动化研究所: 中国科学院研究生院, 2012 作者:  李威 收藏  |  浏览/下载：62/0  |  提交时间：2015/09/02 目标的轮廓跟踪  目标的区域跟踪  表观模型  contour based object tracking  region based object tracking  observation model
