卷烟工厂生产异常信息分析及推送系统

卷烟工厂信息化程度高,采集了丰富的生产数据,如何有效利用这些生产数据来监控生产过程中的异常信息,是本文研究重点.在以往的监控中,管理者通过生产看板和人工反馈发现异常信息,并做出调整.这种方式对异常信息的响应速度慢,且存在疏漏.因此,本文提出了一种卷包车间生产异常信息分析方法来获取有效异常信息,同时将该信息通过移动平台推送给相关管理人员,从而提高异常信息响应能力和生产管控水平.     

微电子封装位置在线实时图像识别算法研究

提出一种针对流水线上微电子点胶封装位置的在线实时图像识别算法。通过对封装位置所在圆的颜色特征分析,提取R分量进行图像灰度化,采用迭代法对灰度图像进行阈值分割去除复杂背景得到二值图像,利用中值滤波法平滑二值图像消除分割后的噪声,运用Sobel算子提取边缘获得边缘信息,利用Hough变换找出边缘信息中待识别圆的中心位置,完成对封装位置的检测。实验结果表明,利用机器视觉技术可以快速、准确地对微电子封装位置进行定位,具有很好的理论和实际应用价值。     

Implementation issues in RFID-based anti-counterfeiting systems

RFID has emerged as a potential tool to combat product counterfeiting, which undermines the global economy hugely. Recently, a number of anti-counterfeiting approaches have been proposed for such purpose. This paper presents a track-and-trace system for RFID-based anti-counterfeiting, and addresses possible implementation issues, such as tag selection, product tagging, tag programming and locking. A packaging line for bottled products is developed and integrated with the proposed system for investigation of these issues. Experiments are conducted to determine the critical tag moving speed beyond which the tag programming rate or reliability of tagged products being transferred on a convey drops significantly. The critical tag moving speed is vital not only for determining the maximum production throughput possible, but also for setting up RFID equipment needed to ensure tagged products with erroneous tagging can be sorted out from the packaging line accordingly.     

消费者在线评论有用性影响因素模型研究

消费者在线评论的价值已经得到消费者和在线零售商的公认,对评论有用性的研究已经成为新的研究热点。从减少消费者决策风险出发,在感知诊断性概念基础上定义了评论有用性概念,构建了一个评论有用性影响因素模型。从传播说服理论的维度考察,评论等级、评论长度、好评率和使用互联网经验是影响评论有用性的重要因素。商品类型对评论有用性具有调节作用。

系列变螺距螺杆的设计计算

为了使罐头包装机具有柔性加工的功能并提高设备利用率,根据圆柱形罐的螺杆供送机构的原理,设计开发了可调变螺距螺杆供送机构和对应不同罐径的系列变螺距螺杆。根据对罐的运动规律要求,给出了变螺距螺杆结构参数的设计计算方法以及罐的运动规律的计算分析方法。阐明了罐运动规律与螺杆长度、罐直径、螺距、螺距数之间的关系。研究的变螺距螺杆的设计计算及运动规律分析方法适合常用的罐径系列。     

A private versus a public space: Anonymity and buying decorative symbolic goods for avatars in a virtual world

The virtual world has become a new channel in which people can contact with others, and organizations can provide service to their customers. Selling symbolic virtual goods has also emerged as a new economy in the virtual world. Such symbolic goods cannot facilitate people to accomplish any specific tasks; people buy them simply to decorate their avatars. This study is based on the theories of symbolic consumption, self-presentation, and computer-mediated environment, to investigate why people buy decorative symbolic goods in the virtual world. The results show that people buy symbolic virtual goods for both emotional and social values. While user perceived social presence and telepresence affect both social and emotional value of symbolic goods, individual self-presentation motivation affects only social value. Besides, anonymous users in the virtual world show behaviors that differ with non-anonymous ones.
