基于匹配点逐层过滤的岩体点云配准方法

岩体点云配准是岩体三维重建与分析的基础。经典的点云配准方法虽然能够很好地适用于普通点云,但对于岩体点云并不能获得足够的精度。由于岩体点云表面结构复杂,且大部分区域为平面,基于岩体点云的这些特点,提出通过几何特征逐层过滤匹配点的岩体点云配准算法,引入匹配点对的协方差矩阵的特征值和特征向量矩阵,以及曲率、主方向等几何特征逐层过滤匹配点对,精确地找到匹配点对。在不同岩体点云上的实验测试与分析结果表明,该算法在准确度上有明显优势。

Financial Feeling: An Investigation of Emotion and Communication in the Workplace

There is growing interest in the role of emotion when considering communication in the workplace. This work has most often considered workers in front-line service positions in investigations of emotional labor, and human service workers in investigations of empathy and emotional work. In this study, we consider processes of both emotional labor and emotional work in the financial planning profession. Financial planners occupy a role requiring ongoing relationships with clients, conversations about the often emotional topic of money, and a need to manage emotion in a variety of interaction contexts. Thus, from extant theory and literature regarding emotion and communication, we proposed research questions regarding the roles of emotional labor and emotional work in the financial planning profession. These questions were investigated in a web-based survey study of almost 300 professional financial planners and supporting interviews with 14 financial planners. Results indicate support for existing theory on emotional work, extensions to current research regarding emotional labor, and important implications for the role of emotion and communication in a range of professional service roles.     

Communicating Knowing Through Communities of Practice: Exploring Internal Communicative Processes and Differences Among CoPs

Knowing is an enacted, communicated process that is difficult to observe, let alone manage, in organizations. Communities of practice (CoPs) offer a productive solution for improving knowledge and knowledge management, but the communicative processes that enact CoPs have not been explored, leaving CoPs as an organizational black box. This research extends CoP theory as a means to determine the presence of a CoP and distinguish between various CoPs, and as a practical means to evaluate the communicative processes of organizational knowledge. CoPs enact the communicative nature of knowing through the elements of mutual engagement, negotiation of a joint enterprise, and shared repertoire. Specifically, two groups of volunteers are examined through a combination of participation, observation, and interviews in order to explore CoP theory as a dynamic system for examining and evaluating organizational knowledge.     

英国公共服务广播面临的问题及对策

公共服务广播(Public Service Broadcasting,在本文中主要指电视广播)在英国的历史由来已久,公营的立法体制保证了节目较为丰厚的资金来源,也催生了高品质的节目内容.英国公共广播电视机构出品的节目通常是由本国制作的原创性作品,内容精良,创意新颖,很少是来自国外的舶来品.为了保证公共广播电视节目的公众服务性,英国广播电视和通信的最高管理机构--通信办公室(the Office of Communications,Ofcom)还会定期对公共广播电视机构进行评估,考察它们是否达到了公共服务广播的目标,并对之如何保持和加强公共广播的高品质服务提出建议.
