Temperature dependence of surface enhanced Raman scattering on C<Subscript>70</Subscript>

The temperature dependence of surface enhanced Raman scattering of the C70 molecule is reported. The Raman scattering of C70 molecules adsorbed on the surface of a silver mirror was measured at different temperatures. The experimental results indicate that the relative intensities of the Raman features vary with the temperature of the sample. When the temperature decreases from room temperature to 0℃, the relative intensifies of certain Raman bands decrease abruptly. If we like the strongest band 1565cm^-1 as a standard value 100, the greatest decrease approaches to 43%. However, with the further decrease in the temperature these relative intensities increase and resume the value at room temperature. And such a temperature dependence is reversible. Our results show that the adsorption state of the C70 molecules on the silver surface around 0℃ changes greatly with the temperature, resulting in a decrease in relative intensities for some main Raman features of C70 molecule. When the temperature is lower than 0℃, the adsorption state changes continually and more slowly. Synchronously, eight new Raman features, which have not ever been reported in fiterature, are observed in our experiment and this enriches the basic information of the vibrational modes for C70 molecule.

Temporal Memory Reinforcement Learning for the Autonomous Micro-mobile Robot Based-behavior

This paper presents temporal memory reinforcement learning for the autonomous micro-mobile robot based-behavior. Human being has a memory oblivion process, i.e. the earlier to memorize, the earlier to forget, only the repeated thing can be remembered firmly. Enlightening forms this, and the robot need not memorize all the past states, at the same time economizes the EMS memory space, which is not enough in the MPU of our AMRobot. The proposed algorithm is an extension of the Q-learning, which is an incremental reinforcement learning method. The results of simulation have shown that the algorithm is va|id.

基于GPR与概率神经网络的城市道路路基病害预警模型研究

近年来由道路路基病害所导致的城市道路塌陷事故频繁发生,造成人员伤亡和巨大的经济损失。针对城市道路路基病害所带来的诸多问题与安全隐患,提出了一种基于探地雷达与概率神经网络的城市道路路基病害预警模型。首先在分析路基病害成因的基础上建立了城市道路路基病害评价指标体系;然后依托城市道路路基病害动态演化物理模型,使用探地雷达采集并积累样本数据;最后基于样本数据建立概率神经网络预警模型并进行仿真分析,结果表明预警准确率达到88.9%。该预警模型在郑州市中牟县的滨河路和荟萃路进行了应用试验,预警结果与实际情况基本吻合,表明该预警模型可对城市道路路基病害做出有效预警,为道路养护和工程整治设计提供技术支撑。     

Efficient Asymmetrical Extended Designs Under Wrap-Around L_2-Discrepancy

The purpose of the present article is to introduce a class of mixed two-and three-level extended designs obtained by adding some new runs to an existing mixed two-and three-level design.A formulation of wrap-around L_2-discrepancy for the extended designs is developed. As a benchmark of obtaining(nearly) uniform asymmetrical extended designs, a lower bound to the wrap-around L_2-discrepancy for our proposed designs is established. Thorough numerical results are displayed, which provide further corroboration to the derived theoretical results.
