Living Library源于丹麦，中文翻译为“真人图书馆”，本文从真人图书馆的起源、发展等方面进行分析，指出国内的Living Library存在的不足之处，并提出相关建议，图书馆要利用Living library平台，转变传统服务模式，开创新的知识服务体系。

Living Library derived from Denmark is translated into “Zhen Ren Library”. In this article, the author analyses the origin and development of Living Library, and points out its deficiency and gives suggestions. Modern Library needs to make use of Living Library as a platform, change the traditional service mode and set a new system of knowledge service.

在传统Live-wire算法中,两个人工选定节点之间的最优路径被定义为具有最小累计能量的路径。因此传统live-wire算法在分割边缘转折剧烈的物体时,为了保证分割的正确性就需要人工添加较多的节点,从而增加整个分割过程的耗时。提出一种基于可控平均代价路径的新型Live-wire算法,并从理论上证明,传统live-wire算法其实是提出的新型算法的一种特例。实验表明,新型Live-wire算法与传统算法相比,能在保证精度的同时减少人工设定的节点个数,从而加快整个分割过程的速度。

In the original live-wire algorithm, optimality is defined as the minimum cumulative cost path from a seed point to an-other, where the cumulative cost of a path is the sum of the local edge costs on the path. Consequently, when delineating a boundary with acute concaves and convexes, more seed points are required which can become very time consuming to calculate. This paper proposes an improved live-wire algorithm where the optimality is redefined as the minimum average cost path be-tween two seed points. In theory, the original live-wire algorithm is only a special case of the improved algorithm. Experiments conduct on a variety of image types have shown that this improved live-wire algorithm requires less seed points than the original algorithm when delineating the same boundary and as a result, reduces the time required to complete the calculation.

社会认知主义对话理论关注语言的社会对话本质及社会文化环境下学习者与他者的对话;Living Library(活人图书)是采用"对话"的形式进行面对面交流的一种新型学习形式。本文以对话理论融合"Living Library"活动的组织及实践模式,从一个新的切入点探讨构建大学英语"Living Library"口语课堂,阐述其理论基础及课堂运作模式,并对其实际教学进行反思和总结。

Theory of Dialogism in the field of Social Cognitivism follows languages′nature of social dialogicality and the dia-logue between the learner and “the other” in the social cultural environment;Living Library is a new face-to -face dialogic learning approach .This paper integrates them and probes into the construction of “Living Library” spoken English class from a new perspective , illustrates its theoretical foundation , its working pattern , eventually concludes and reflects the virtual teaching.

描述一种分享Http Live Streaming流媒体,同时对服务器和播放器透明的播放器中间件HLS-Share。HLS-Share通过手机节点间的协作计算,使手机共享3G网络带宽,减少3G网络流量,加速观看Http Live Streaming流。HLS-Share采用基于事件驱动的方法在本地P2P网络中挑选部分节点作为中继节点负责分享从Internet获取的Http Live Streaming流。通过实验验证了相比于每部手机独立使用3G网络观看视频,HLS-Share在引入极小的CPU使用率的代价下,能够实现共享带宽、加快缓存速度的作用,并且消耗的电量小于前者。

This paper describes a player middleware named as HLS-Share,it shares streaming media of Http Live Streaming,and is transparent to both the server and the player simultaneously.HLS-Share enables mobile phones nodes share their 3G networks bandwidth and cut down 3G networks flow by cooperated computation between the mobile phones’nodes,which speeds up Http Live Streaming watching. HLS-Share selects part of the nodes from local P2P network by using event-driven based means and employs them as the relay nodes in charge of sharing the Http Live Streaming data obtained from Internet.In this paper we verify through the experiment that comparing with each mobile phone watching video in 3G network independently,HLS-Share is able to realise bandwidth sharing,accelerate the role of cache speed,and has less power consumption than the former at the cost of introducing slight CPU utilisation rate.
