作者： WANG Zhao-hui ZHENG Guo-lei zhu Xin-xiong School of Mechanical Engineering ＆ Automation Beijing University of Aeronautics and Astronautics Beijing 100083 China

The efficient and reliable human centered design of products and processes is a major goal in manufacturing industries for numerous human factors must be taken into account during the entire life cycle of products. A multi-agents intelligent design system is presented for manufacturing process simulation and products＇ ergonomic analysis. In virtual design environment, the virtual human with high-level intelligence performs tasks＇ operation autonomously and shows optimum posture configuration with ergonomic assessment results in real time. The functions are realized by intelligent agents architecture based on a modem approach derived from fuzzy multi-objects decision-making theory. A case study is presented to demonstrate the feasibility of the suggested methodology.

针对目前带倾斜修正的电子磁罗盘由于倾角测量误差大,导致航向角测量精度低的问题,提出了一种基于三轴加速度传感器倾角测量模型进行误差补偿的方法。首先,研究了磁罗盘的倾角测量误差对航向角测量精度的影响,分析了加速度传感器测量倾角的原理及其误差来源。然后,构建了三轴加速度传感器测倾角的物理模型,建立了相应的数学模型,采用了改进的最小二乘法对其进行参数识别,完成对倾角测量误差的补偿。最后,利用BP神经网络算法对周围环境的罗差进行修正。实验结果表明:通过对倾角测量误差的补偿,在°3 0°范围内,其倾角测量误差控制在°0.3°之内;能够将磁航向角测量误差由倾角测量误差补偿前的°1.8°降低到°0.6°,提高了电子磁罗盘的测量精度。

在采用交替非负最小平方方法进行非负矩阵分解的过程中,每次的迭代更新通常很难直接计算出唯一的最优非负分解矩阵.但是,若采用矩阵变换方法,则对于变换后的代价函数,就有可能获得唯一的最优非负分解矩阵.对基于矩阵变换的非负矩阵分解... 详细信息

在采用交替非负最小平方方法进行非负矩阵分解的过程中,每次的迭代更新通常很难直接计算出唯一的最优非负分解矩阵.但是,若采用矩阵变换方法,则对于变换后的代价函数,就有可能获得唯一的最优非负分解矩阵.对基于矩阵变换的非负矩阵分解进行了理论分析,提出了2种基于矩阵变换的非负矩阵分解算法.该算法具有与已有算法相似的计算复杂度,却可有效减少非负矩阵分解的更新次数.

Ternary content-addressable memory(TCAM) is an indispensable component of lookup tables in switches or ***, it suffers from expensive and inflexible update operations and cannot fulfill the demand for rule updates in switches enabling software-defined networking(SDN). The main reason is that TCAM stores rules from top to bottom in decreasing order of priority for disambiguation. Updating a TCAM is similar to the insertion sort that takes O(n) time,
