43023.EPS/LTE和WLAN/802.11的安全性比较研究
[信息传输、软件和信息技术服务业] [2013-12-13]
Security in the wireless access network gained increasing interest over the last years. Its implementation varies from one access network to another. The current trend in wireless access network is towards implementing mechanisms for mobility management namely handoff process and quality of service control. Consequently, security should be taken into consideration at each handoff process which may occur between different technologies (inter-technology) or within the same (intra-technology). At the same time, security provisioning impact on network performances (e.g. end-to-end delay, throughput) should be controlled. This chapter aims to give a better understanding of security measures and protocols available in two distinct wireless network families, namely the Wireless Wide Area Network (WWAN) and the Wireless Local Area Network (WLAN). WWAN family includes the wide coverage area technologies such as the Long-term Evolution (LTE), also named as Evolved Packet System (EPS). On the other hand, WLAN are characterized by having a small coverage area. It includes the WiFi (802.11) technology. Each time, the chapter highlights the mechanisms employed by access network to ensure the trade-off between secured mobility and application requirements in terms of delay and throughput.

43025.宜居社区交通系统的会议总结
[信息传输、软件和信息技术服务业,交通运输、仓储和邮政业] [2013-12-13]
This meeting was the fifth in a series of spotlight conferences funded by the university transportation centers (UTC) program of the U.S. Department of Transportations Research and Innovative Technology Administration (RITA). The UTC program awards grants to universities across the country to advance the state of the art in transportation research, to conduct technology transfer activities, and to educate the next generation of transportation professionals. TRB assembled a planning committee, appointed by the National Research Council (NRC), to help organize and develop the conference program. The planning committee was chaired by Lisa Aultman-Hall of the University of Vermont. Committee members provided expertise in bicycle and pedestrian transportation, transit planning and operations, land use, urban street design, and management of transportation organizations. The planning committee was responsible solely for organizing the conference, identifying speakers, reviewing submitted poster abstracts, and developing topics for the breakout group discussions.

43027.2012-2013年中国手机输入法用户行为研究报告
[信息传输、软件和信息技术服务业] [2013-12-13]
手机输入法作为必备应用,用户属性与手机上网用户属性匹配度高;拼音输入法用户占比为79.8%。使用手机自带输入法和第三方输入法的用户占比相当,约为49.0%。搜狗输入法用户占第三方输入法用户近七成;超四成的手机输入法获取请求不通过移动互联网实现,有30.6%的用户通过PC上网下载手机输入法;输入速度和记忆功能是用户首要考虑的因素; 超六成用户对输入速度满意,最希望手机输入法完善纠错功能;从PC端到手机端,部分用户转向手写输入法;从PC端到手机端,百度、搜狗留住了超八成的用户,搜狗输入法在手机端吸引其他品牌输入法用户上优势明显;非拼音类输入法:用户试的多,用的少。非拼音类输入法在输入速度、输入准确性等功能性要求方面仍无法满足用户。尽管用户也想尝试多种类型的输入方式,但最终由于体验不佳而转向传统的拼音输入;语音输入法:免打字是优势,识别慢成弊端。55.8%的用户因为“输入方便,避免打字繁琐”选择语音输入法,但也42.5%的语音输入法用户认为“识别慢,需等待”影响其输入体验。

43028.公共交通系统固定和灵活路线的整合,第一阶段
[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2013-12-13]
To provide efficient public transportation services in areas with high demand variability over time, it may be desirable to switch vehicles between conventional services (with fixed routes and schedules) during peak periods and flexible route service during low demand periods. We call this possibility a variable-type service. In this research project we compare conventional, flexible and variable-type service alternatives optimized for various conditions in order to explore when variable-type bus services might be preferable to pure ones. The optimization models used for purely conventional or flexible services are adapted from previous studies. These models are integrated into a new model for optimizing variable-type bus services. The results of sensitivity analyses show how the demand variability over time and other factors affect the relative effectiveness of conventional, flexible and variable-type bus services.
