Recurrence of Transitive Points in Dynamical Systems with the Specification Property

Acta Mathematica Sinica,English Series 2018年第12期34卷 1879-1891页

作者： xiao yi wang Yu HUANG School of Mathematics and Statistics Zhaoqing University Zhaoqing 526061 P. R. China Department of Mathematics Sun Yat-sen University Guangzhou 510275 P. R. China

Let T ： X →X be a continuous map of a compact metric space X. A point x E X is called Banach recurrent point if for all neighborhood V of x, （n ∈ N ： T^n（x） ∈ V} has positive upper Banach density. Denote by Tr（T）, W（T）, QW（T） and BR（T） the sets of transitive points, weakly almost periodic points, quasi-weakly almost periodic points and Banach recurrent points of （X, T）. If （X, T） has the specification property, then we show that every transitive point is Banach recurrent and O≠ W（T） n Tr（T） ≠ W＊（T） ∩ Tr（T） ≠ QW（T） ∩ Tr（T） ≠ BR（T） ∩ Tr（T）, in which W＊（T） is a recurrent points set related to an open question posed by Zhou and Feng. Specifically the set Tr（T） M W＊（T）／ W（T） is residual in X. Moreover, we construct a point x E BR ／ QW in symbol dynamical system, and demonstrate that the sets W（T）, QW（T） and BR（T） of a dynamical system are all Borel sets.

A Direct Parametric Approach to Spacecraft Attitude Tracking Control

引用

International Journal of Automation and computing 2017年第5期14卷 626-636页

作者： xiao-yi wang Guang-Ren Duan Center for Control Theory and Cuidance Technology Harbin Institute of TechnologyHarbin 150001China

Through the direct parameter approach, a solution for spacecraft attitude tracking is presented. First of all, the spacecraft attitude tracking control model is built up by the error equation of the second-order nonlinear quaternion-based attitude system. Based on the control model, a suitable controller is designed by the direct parameter approach. Compared with other control strategies, the direct parameter approach can offer all degrees of freedom for the controller to satisfy the requirements for system properties and turn the original nonlinear system into closed-loop linear system. Furthermore, this paper optimizes the controller according to the robustness, limitation of controller output and closed-loop eigenvalue sensitivity. Putting the controller into the original system, the state response of the closed-loop system and the output of controller are plotted in Matlab to verify the availability and robustness of the controller. Therefore, the controlled spacecraft can achieve the goal of tracking on the mobile target with the external disturbance torque.

光学精密工程 2005年第4期13卷 397-402页

作者： GAO Jin-song XU ying wang xiao-yi wang Tong-tong Optical Technology and Research Center Changchun Institute of Optics Fine Mechanics and Physics Chinese Academy of Sciences Changchun 130022 China

ITO （indium oxide doped with tin） thin films were deposited on glass substrates by using ITO pellet with a composition of w（In2O3）=90% and w（SnO2）=10% by electron beam evaporated with End-Hall ion source assisted without extra heating. The rate of deposition and flow rate of oxygen were measured and changed to obtain the best properties of ITO thin films. Furthermore, the post annealing process was done in vacuum at different annealing temperatures for 2 h and at 400℃ for different keeping time, respectively. The relation between optical, electrical properties and structure was discussed in detail.

Pancreatic cancer is one of the most common gastrointestinal tumors, with its incidence staying at a high level in both the United States and China. However, the overall 5-year survival rate of pancreatic cancer is still extremely low. Surgery remains the only potential chance for long-term survival.

The Rabi oscillations in two-component Bose-Einstein condensates with a coupling drive are studiedby means of a pair of bosonic operators. The coupling drive and initial phase difference will affect the amplitudeand the period of the Rabi oscillations. The Rabi oscillations will vanish in the evolution of the condensate densityfor some special initial phase differences (ψ = 0 or π). Our theory provides not only an analytical framework forquantitative predictions for two-component condensates, but also gives an intuitive understanding of some mysteriousfeatures observed in experiments and numerical. simulations.
