Orbit systematics in anisotropic Kepler problem

We revisit the Anisotropic Kepler Problem (AKP), which concerns with trajectories of an electron with anisotropic mass term in a Coulomb field. This is one of the most fundamental fields in Quantum Chaos. Nowadays various quantum systems are challenging us. Classical theories of these may have chaos. Quantum mechanics have developed from integrable cases and may have to be reformulated for such cases. AKP then serves as a suitable testing ground for quantum chaos. We first review a pioneering work by Martin Gutzwiller (J Math Phys (1977) 18:106). We shall show the systematics of the trajectories using ample figures from an extensive numerical analysis. Then we focus on the rolê of hyperbolic singularities and we comment on the approximations in an analytic formulation. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

考虑施工顺序及遮栏效应的静压群桩挤土位移场研究

基于应变路径法及源汇法理论,建立了已存在桩情况下单桩挤土位移场。在此基础上,结合拉格朗日插值函数推导出了考虑施工顺序及遮栏效应的群桩挤土位移场的解析解。该解较各桩的简单叠加更符合工程实际情况,而且能够简化为不考虑施工顺序的静压群桩挤土位移场的解答。利用得到的解析解对群桩产生的挤土位移场进行了分析,结果表明:与忽略施工顺序及遮栏效应的群桩挤土位移场相比,考虑施工顺序及遮栏效应的迎桩面挤土位移较大,而背桩面的挤土位移较小。

基于S型曲线轨道的机械系统残留振动抑制

针对车床进给系统,起重机以及材料搬运系统等广泛应用于各种工业场合的机械系统中所存在的振动问题,提出一种基于S型曲线轨道生成法实现其残留振动的抑制。给出含有振动特性的机械系统的简易动力学模型,基于该模型通过理论分析得到可以抑制残留振动的S型曲线轨道的充分必要条件,数值仿真验证该条件的有效性,将上述条件应用于桥式起重机系统并通过实验结果进一步验证其有效性。该轨道可应用于常用的工业控制器中,从而降低其安装成本。     

Optimized trajectory recovery of on‐road vehicles from monocular videos with multiple constraints

In this paper, we propose an optimized trajectory recovery algorithm for on‐road vehicles from monocular videos, which considers multiple constraints between frames in a sliding window. We build a linear system to optimally estimate the camera rotation matrix corresponding to the first frame in each sliding window, and calculate the camera center estimation. The camera centers are determined by the estimation and prediction eventually. The whole process is applied to the sequential video frames by sliding the window. The advantage of the proposed algorithm is that it is able to reduce the drift error, which is a challenge for the existing algorithms, since multiple constraints in a sliding window are used to optimize the camera poses. We test the algorithm both on synthetic data and real data, and compare it with existing algorithms. It shows a higher accuracy of reconstruction and is suitable to recover a better trajectory of on‐road vehicles from monocular videos. © 2014 Institute of Electrical Engineers of Japan.
