On social Web sites

Today hundreds of millions of Internet users are using thousands of social Web sites to stay connected with their friends, discover new “friends,” and to share user-created contents, such as photos, videos, social bookmarks, and blogs. There are so many social Web sites, and their features are evolving rapidly. There is controversy about the benefits of these sites, and there are social issues these sites have given rise to. There are lots of press articles, Wikipedia articles, and blogs—in varying degrees of authoritativeness, clarity and accuracy—about some of the social Web sites, uses of the sites, and some social problems, and business challenges faced by the sites. In this paper, we attempt to organize the status, uses, and issues of social Web sites into a comprehensive framework for discussing, understanding, using, building, and forecasting the future of social Web sites.

煤矿安全生产监控系统联网

分析了我国乡镇煤矿安全生产状况:乡镇煤矿煤炭产量约占全国煤炭产量的37.8%,发生死亡事故起数和死亡人数却占全国煤矿事故总起数的73.5%和74.1%,百万吨死亡率是国有重点煤矿的7倍。乡镇煤矿事故频发的原因包括技术装备落后、矿井系统不完善、专业技术人才匮乏、安全教育培训滞后、安全责任不落实、现场管理松弛、隐患排查治理不到位等,而技术装备落后和机械化、自动化、信息化程度低是最主要的原因。煤矿安全生产监控系统联网是加强煤矿安全生产监管的重要措施之一。提出了煤矿安全生产监控系统联网方法:中心站(或主机)应及时向监控中心上传有关监控信息;中心站(或主站)和监控中心应具有符合IEEE802.3协议的以太网接口等。     

Social networking and digital gaming media convergence: Classification and its consequences for appropriation

Within the field of Information Systems, a good proportion of research is concerned with the work organisation and this has, to some extent, restricted the kind of application areas given consideration. Yet, it is clear that information and communication technology deployments beyond the work organisation are acquiring increased importance in our lives. With this in mind, we offer a field study of the appropriation of an online play space known as Habbo Hotel. Habbo Hotel, as a site of media convergence, incorporates social networking and digital gaming functionality. Our research highlights the ethical problems such a dual classification of technology may bring. We focus upon a particular set of activities undertaken within and facilitated by the space—scamming. Scammers dupe members with respect to their ‘Furni’, virtual objects that have online and offline economic value. Through our analysis we show that sometimes, online activities are bracketed off from those defined as offline and that this can be related to how the technology is classified by members—as a social networking site and/or a digital game. In turn, this may affect members’ beliefs about rights and wrongs. We conclude that given increasing media convergence, the way forward is to continue the project of educating people regarding the difficulties of determining rights and wrongs, and how rights and wrongs may be acted out with respect to new technologies of play online and offline.

基于云计算的社交网络流量识别与管理研究

目前社交网络发展迅速,但国内外对于社交网络流量的识别并未给出有效的方法,文章以三种主流的社交网络为研究对象,深入分析了各社交网络流量的净荷特征和流量特征,给出了各个社交网络数据流量的识别方法。在此基础上,利用基于净荷特征与流量特征相结合的方法对采自校园网的流量进行了识别和分析,实验结果表明,基于净荷特征与流量特征相结合的方法的识别准确率较单独使用每一种方法的识别准确率有明显提高。     

物联网中嵌入式TCP/IP协议栈的设计技巧

物联网是一种新兴的通信应用网络,而物联网应用的核心技术之一就是实现嵌入式设备的网络化。实现嵌入式设备网络化的方式多种多样,其中最重要的一种方式就是在嵌入式设备中实现TCP/IP协议栈。本文主要介绍了物联网的基本概念并对嵌入式系统的基本情况、发展现状进行了简要阐释,重点分析了在实现嵌入式TCP/IP协议栈的过程中应当遵循的一些实现技巧,从而为嵌入式设备上网提供了条件,为物联网技术的实现打下了坚实的基础。     

EoC带宽增强方案的设计和实现

为提升使用EPON+EoC方案进行双向化改造后的有线电视网络用户的下行带宽效果,提出EoC带宽增强方案。在原有EoC通道基础上,通过新增QAM通道,统一管理、分配和使用新增的QAM通道资源和原有的EoC通道资源,并通过调整新增资源数量实现渐进扩容。基于OCTEON CN5860多核网络处理器平台设计并实现该方案中的核心设备,即融合通道网关。性能测试结果表明,该设备单个处理核心可以提供920 Mb/s的吞吐量,具有良好的可扩展性。     

基于BLE Mesh组网应用系统设计

针对传统智能产品组网方式复杂、耗电量大、同步控制以及需要独立系统网关等问题,设计了基于低功耗蓝牙(BLE) Mesh技术的室内发光二极管(LED)灯及温湿度监控系统.测试表明:系统低功耗的性能优于目前主流的无线芯片ZigBee,WiFi,同时提出了一种以解决Mesh网络中功耗问题的新网络拓扑结构,从而优化了BLE Mesh的网络功耗,且系统能够准确无误控制室内的设备以及监测各个设备的状态参数.该应用会在未来智能物联网家居产品领域具有较好的市场前景.
