Indium oxide(In_(2)O_(3)),as a promising candidate for CO_(2)hydrogenation to C_(1) products,often suffers from sintering and activity decline,closely related to the undesirable structural evolution under reaction *** on the comprehension of the dynamic evolution,this study presents an efficient strategy to alleviate the agglomeration of In_(2)O_(3)nanoparticles by the surface decoration with highly dispersed silica species(SiO_(x)).Various structural characterizations combined with density functional theory calculations demonstrated that the sintering resulted from the over-reduction,while the enhanced stability originated from the anchoring effect of highly stable In-OSi bonds,which hinders the substantial formation of metallic In(In^(0))and the subsequent agglomeration.0.6Si/In_(2)O_(3)exhibited CO_(2)conversion rate of10.0 mmol g^(-1)h^(-1)at steady state vs.3.5 mmol g^(-1)h^(-1)on In_(2)O_(3)in CO_(2)*** steady-state activity was also achieved on Pd-modified *** to the traditional Pd/In_(2)O_(3)catalyst,the methanol production rate of Pd catalyst supported on 0.6Si/In_(2)O_(3)was enhanced by 23%,showing the potential of In_(2)O_(3)modified by SiO_(x)in serving as a platform *** work provides a promising method to design new In_(2)O_(3)-based catalysts with improved activity and stability in CO_(2)hydrogenation.

An Experimental Study on Measurement Errors of Inertial Sensors in Smartphones

第30届中国控制与决策会议

作者： Jian Song Baoqi Huang runze yang College of Computer Science Inner Mongolia University

In recent years, inertial sensors in smartphones are used more and more widely, and play great roles in navigation, human movement monitoring and other applications. Hence, it is significant to understand accuracies of smartphone sensors. Many researchers pay much attention on how to reduce or compensate measurement errors of sensors, but the characteristics of measurement errors produced by the inertial sensors in smartphones are still *** this paper, the measurement errors of the inertial sensors embedded in smartphones are carefully investigated through an experimental study. To do so, extensive experiments have been carried out to collect inertial measurements from both the smartphones and a motion tracking system（i.e. Xsens MTw） that delivers much higher precision than the smartphone. In the first place, the experiments demonstrate that the error distribution is dependent on smartphone’s motions. Specifically, when the smartphone is stationary, the measurement errors of the inertial sensors satisfy the t Location-Scale distribution and the Gaussian distribution;while the smartphone moves at a low speed, the distribution can be approximated as the Gaussian distribution;while the smartphone moves quickly, the distribution also satisfies the t Location-Scale distribution. Our studies establish a basis for future studies in establishing error models of the inertial sensors.

针对现有口腔扫描设备获取的网格数据存在自相交、孔洞等一系列问题,提出一种快速、有效的自相交检测算法.为了降低全局网格自相交检测的时间复杂度,引入一种特殊的八叉树算法,利用细分的思想把三角面片放置在不同的立方体内以实现快速自相交检测,并通过删除操作消除错误连接;为了修复上一步骤中形成的大量网络孔洞,设计一种特殊的双边数据结构,能够快速有效地检测单连通封闭孔洞,并正确处理多个孔洞共用同一顶点的问题;孔洞修复完成后,利用拉普拉斯平滑策略对孔洞区域进行处理,获得过渡自然平滑的补洞效果.在80套口腔内扫描数据上的实验结果表明,所提算法不仅能够快速检测网格数据的自相交区域,而且能够高效完成补洞操作;与现有算法相比,在网格数量大于100万的数据上,处理速度提高大约10倍.
