摘要：We have developed a wearable system for mobile distributed collaboration called HandsInAir using emerging wireless and mobile technologies. This system was developed to support real world scenarios in which a remote mobile helper guides a local mobile worker in the completion of a physical task. HandsInAir consists of a helper unit and a worker unit. Both units are equipped with wearable devices having the same hardware configuration, but running different pieces of software to support the distinct roles of the collaborators (helper and worker). The two sides are connected via a wireless network and the collaboration partners can communicate with each other via audio and visual links. In this paper we describe the technical implementation of the system and present a preliminary evaluation of it. The paper concludes with a brief discussion of possible future work for further improvements and new developments.

摘要：In this study, taking cultivated land fertility evaluation data for example, we conducted a preliminary study of GIS theory and spatial data management, and construct the frame system of mobile structure based on the three layer structure model of application layer, business logic layer and data layer. Then we established a spatial data storage model, which has unified the data standards and achieved the management of spatial data and attribute database. Taking ArcGIS API for iOS as GIS platform, Xcode as the tool, we have realized the functions of data integration, data query, data statistics and fertilization recommendation, and constructed the management and service platform of mobile fertilization expert system.

摘要：为了解决RIA手机应用中的访问效率问题,提出一种基于mobile Agent的手机动漫阅读器构建模型,该模型采用带mobile Agent的混合拓扑结构,将服务器计算量转移到Agent节点进行,并针对该系统建立了排队模型和系统费用模型,通过分析和仿真得出了一定目标下的系统最优解。

摘要：由于目前流行的 mobile IP切换都假定了 IP层无法得到链路层信息 ,所以 ,只能通过周期性地广播代理广告来实现位置移动检测 ,因而浪费了无线带宽 ,延长了切换时间 ,降低了 TCP性能 .一方面随着无线网络带宽的不断增高(当前的带宽已达到 2 Mbps) ,无线链路上的信息传输延迟将越来越小 ;另一方面 ,在移动计算环境中 ,如果 IP层能够及时获得一些无线链路层的信息 ,那么上述的缺点就能被有效地克服 .本文提出了一种具有链路层支持的快速 mobile IP切换算法 ,分析了快速 mobile IP切换算法和三个已知切换算法的切换时间 ,并在我们已完成的宽带无线 IP网络中对上述切换算法进行了对比实验 .理论分析和对比实验均表明快速 mobile IP切换算法的延迟降低了一个数量级且极大地改善了

摘要：分析目前手机服务技术并选择J2ME利用手机上网方式提供地图服务,采用mobileSVG组织地图数据,在此基础上设计基于J2ME/mobileSVG的手机地图服务,并对其关键技术进行分析。

摘要：Enterprise market research is mainly tend to the traditional paper investigation and telephone interview, The traditional survey method has wasted a lot of human material and financial resources, it also isn’t beneficial to statistical analysis and survey efficiency is low, so it brings a lot of inconvenience to the enterprise. This paper designs survey platform for the industry based on the analysis of the present Internet survey situation and with the help of the existing network platform characteristic. This platform uses the Ajaxand ASP. NET3.5 technology, it is suitable for online survey, voting, electing and testing. It reduces the burden of management and statistics work and improve the quality of the industry survey.
