集装箱信息的条码化研究

现代集装箱码头很多作业已经实现了自动化或半自动化,但码头理货和闸口工作人员仍要用无线手提终端机人工输入集装箱信息。本文研究了使用条码技术(39条码和PDF417码)对集装箱信息进行编码。运用了文本压缩技术,将包含集装箱信息的PDF417码压缩为5行二维条码。通过将集装箱信息的条码化,并借助市场上已有的无线条码数据采集器扫描条码,可以实现码头理货和闸口工作人员录入数据的自动化,降低工作强度,提高生产效率。     

金属材料冲击实验教学分析

在材料力学实验教学中常用简支梁式冲击弯曲试验来测定材料的冲击韧性αk值。并显示试件缺口处的力学特性(韧性或脆性)。由于冲击实验受到多种内在和外界因素的影响,要想正确反映材料的冲击特性,必须在冲击实验中做到标准化和规范化。     

Automatic extraction of 1D barcodes from video scans for drone-assisted inventory management in warehousing applications

The widespread use of barcodes has significantly contributed to accurate, efficient and economic inventory management in warehouses and distribution centres. However, its efficiency has always been limited by the primary method of reading barcodes with a handheld laser scanner. Compared with this reading by line-of-sight at close proximity, vision-based barcode reading algorithms can further improve efficiency, particularly if accompanied by automated data collection platforms such as drones. This paper introduces algorithms that are able to automatically extract barcodes from video data, and verifies their feasibility and promise for inventory management in warehousing applications. Three key techniques corresponding to different recognition levels are proposed: For a known barcode region, a Harris corner detector and Hough transform-based algorithm is applied to quickly estimate the angle by which the frame area needs to rotate to orient the bars vertically for information extraction. Then, the idea of exploiting connectivity and geometry property of barcode areas is proposed to directly recognise multiple barcode regions in a single video frame to eliminate reading difficulties resulting from interactive influence of multiple juxtaposed barcodes, and to save computation time by only processing frame areas of interest for valid barcodes. In addition, a histogram difference-based fast extraction strategy is designed to further improve efficiency by reducing duplicate information processing. Finally, the performance of each technique is evaluated by analysing video data from a large logistics warehouse, demonstrating satisfactory performance in inventory management applications.     

论中国古代货币价值论的特点

通过对中国古代货币价值理论相对西方薄弱的特点、成因与影响进行分析,指出正是因为缺乏对货币价值问题的研讨,导致中国古代货币思想的关注点集中在较次要的方面,无法说明财富增长的动力和根源,也无法正确认识货币在商品交换中的重要作用.货币价值论的薄弱还导致中国古代货币思想与西方相比更多地关注国家财政,对商品市场研讨不足,从而未能形成较完整的理论思想体系.     

The value and security of money. Metallic and fiduciary media in Ferdinando Galiani's Della moneta

This paper proposes a new interpretative framework for Galiani's monetary theory. The main argument is that, by adopting “the methodology of successive approximations” (correctly attributed to him by Luigi Einaudi), Galiani investigated the theoretical foundations of the two archetypal moneys: metallic money and paper money. On these foundations, he developed the model of a complex monetary economy based on the coexistence of a metallic and a fiduciary circulation. The paper also illustrates how the experience of the “public banks” of Naples inspired his analysis, thus shedding new light on the theoretical and institutional richness of his monetary thought.
