弹性函数的几何机理

弹性函数是研究当自变量有微弱变化时,函数的相对变化率。文章构造一条初始弹性直线,从几何的角度分析,弹性函数就是函数的切线斜率与初始弹性直线斜率之比;也是函数在弹性支点的微分与初始弹性直线在弹性支点的增量之比。在修订参考文献的基础上,着重对几何机理进行分析。

Length-based vehicle classification in multi-lane traffic flow

For the realtime classification of moving vehicles in the multi-lane traffic video sequences, a length-based method is proposed. To extract the moving regions of interest, the difference image between the updated background and current frame is obtained by using background subtraction, and then an edge-based shadow removal algorithm is implemented. Moreover, a thresholding segmentation method for the region detection of moving vehicle based on location search is developed. At the estimation stage, a registration line is set up in the detection area, then the vehicle length is estimated with the horizontal projection technique as soon as the vehicle leaves the registration line. Lastly, the vehicle is classified according to its length and the classification threshold. The proposed method is different from traditional methods that require complex camera calibrations. It calculates the pixel-based vehicle length by using uncalibrated traffic video sequences at lower computational cost. Furthermore, only one registration line is set up, which has high flexibility. Experimental results of three traffic video sequences show that the classification accuracies for the large and small vehicles are 97.1% and 96.7% respectively, which demonstrates the effectiveness of the proposed method.     

《共产党宣言》：文本主题、理论主线与实践主调——一种探求马克思主义经典著作的研读方法

马克思主义经典作家思想的流传,主要借助于其撰写的经典文本作为传播载体。《共产党宣言》文本所呈现出的文本主题、逻辑结构、理论主线、运动主体与实践主调足以证明,其生命力在相当大的程度上得益于文本质量。但还有赖于外在的因素。根据具体实践的发展要求,结合马克思主义基本原理,创造出一种新的“中国特色”理论来指导解决现实问题,是对待马克思主义经典著作所应具有的科学态度。     

三线建设与六盘水生态环境之变迂

上世纪60年代中期开始,三线建设在六盘水全面铺开。由于当时重开发建设,轻环境保护,环保意识不强。随着六盘水矿区规模的不断扩大,境内环境开始受到污染,生态遭到破坏。出现“三废”污染严重,地下水下沉、枯竭,森林资源缩减,水土流失严重,自然灾害增多等诸多现象。

A novel algorithm for Ethernet-passive-optical-network dynamic bandwidth allocation based on threshold

The Ethernet passive optical network (EPON) is the next generation of broad-band network technique. A crucial issue in EPONs is the sharing of uplink bandwidth among optical network units (ONUs). This article provides a novel dynamic bandwidth allocation algorithm, i.e. threshold dynamic bandwidth allocation (TDBA), which is based on adaptive threshold, to increase resource utilization. The algorithm uses ONU data-transmitting rate to adjust optical line terminal (OLT) receiving data threshold from an ONU. Simulation results show that this algorithm can decrease average packet delay and increase network throughput in a 10G EPON system.
