面向国家重大科技计划的大学创新体系构建模式研究

大学由于学科局限性、方向单一性、组织分散性等问题很难更好地服务于国家重大科技计划实施。本文分析了我国大学在国家重大科技计划中的作用和地位,总结了我国大学科技创新体系在国家重大科技计划中发挥作用面临的机遇与挑战,提出了面向国家重大科技计划的大学科技创新体系的4层构建模式,从学科方向、创新团队、组织体系、实验环境等4个方面提出了具体的构建方法,为大学更好服务于国家科技创新提供了相应的模式。

Novel satellite transport protocol with on-board spoofing proxy

As a result of the exponential growing rate of worldwide Internet usage, satellite systems are required to support broadband Internet applications. The transmission control protocol （TCP） which is widely used in the Internet, performs very well on wired networks. However, in the case of satellite channels, clue to the delay and transmission errors, TCP performance degrades significantly and bandwidth of satellite links can not be fully utilized. To improve the TCP performance, a new idea of placing a TCP spoofing proxy in the satellite is considered. A Novel Satellite Transport Protocol （NSTP） which takes advantage of the special properties of the satellite channel is also proposed. By using simulation, as compared with traditional TCPs, the on-board spoofing proxy integrated with the special transport protocol can significantly enhance throughput performance on the high BER satellite link, the time needed to transfer files and the bandwidth used in reverse path are sharply reduced.

基于大数据技术的国家科技计划项目评审立项研究

随着科技和经济的发展,国家科技计划项目评审过程中产生大量碎片化的数据,大数据技术可以充分利用这些数据完善创新国家科技计划项目评审。围绕基于大数据技术的国家科技计划项目评审,总结国内外大数据应用于项目管理的现状,分析目前国家科技计划项目评审存在的问题,结合大数据技术提出国家科技计划项目评审的完善方式,包括建设科技资源共享平台,解决项目受理问题,健全评审专家画像与推荐机制,完善项目负责人及项目团队的评价体系,重视科研诚信监控。构建基于大数据技术的国家科技计划项目评审体系,辅助国家科技计划项目评审立项决策,加快实现建设世界科技强国的目标。
