1异构网络中多模终端业务流分发技术研究显示文摘伴随着异构网络的迅猛发展,多模终端日益普及.当终端上有多种不同类型的会话业务流需要传输时,如何根据不同类型业务流的特点、不同网络的当前链路状况、通信费用、传输功耗等因素,在终端所接入的多个网络之间自动地、合理地分发业务流就成为一个非常重要的问题.文中提出了一套针对多模终端业务流分发问题的解决方案,包括支持业务流自动分发的多模终端框架结构及其包含的业务流分发算法.方案引入优先级的概念使得高等级的业务流在网络负载较重时具有使用网络的优先权,同时方案包含了一种权重自生成方法,为影响业务流分发决策的多个属性自动生成权重,减轻了用户负担,避免了由用户直接指定权重的困难.仿真实验的结果表明,文中方案能够根据当前各接入网络的链路状况、不同类型业务流的服务质量需求、传输功耗、通信成本等多个属性,自动为多模终端上运行的各条业务流选择合理的接入网络,同时方案在吞吐量、会话完成率等性能指标上也拥有显著改进.孙毅 葛雨明 HERBORN Stephen DUTKIEWICZ Eryk 2010计算机学报2010,33,6:10
2Oil-bearing fluid inclusions from the Palaeoproterozoic:A review of biogeochemical results from time-capsules >2.0 Ga old显示文摘The observation of oil inclusions trapped prior to 2.0 Ga in Palaeoproterozoic rocks and the ability to obtain detailed molecular geochemical information from them provide a robust way for understanding the early biogeochemical evolution of the Earth. Oil-bearing fluid inclusions (FI) in ca. 2.45 Ga fluvial metaconglomerate of the Matinenda Formation at Elliot Lake, Canada were trapped in quartz and feldspar during diagenesis and early metamorphism of the host rock, probably before ca. 2.2 Ga. The 2.1 Ga FA Formation sandstone of the Franceville Basin in Gabon that hosts the Oklo natural fission reactors has also been discovered to contain abundant Palaeoproterozoic oil-bearing FIs. This oil occurs within H2O and CO2-dominated inclusions trapped in syntaxial quartz overgrowths and intragranular and transgranular microfractures in detrital quartz, and was most likely trapped 2.1-1.98 Ga. Molecular geochemical analyses of both FI oils reveal a wide range of compounds, including n-alkanes, isoprenoids, monomethylalkanes, aromatic hydrocarbons, and trace amounts of complex multi-ring biomarkers including terpanes, hopanes, methylhopanes, steranes and diasteranes. To ensure a reliable interpretation of oil inclusions, a comprehensive series of outside-rinse blanks and procedural system blanks was analysed by gas chromatography-mass spectrometry; quantitative amounts of the hydrocarbons in these blanks were compared to the FI extracts, so as to provide confidence limits on the experimental integrity of each compound class. Maturity ratios based on reliably detected compound classes show that the FI oils were generated in the oil window, with no evidence of extensive thermal cracking. The presence of biomarkers for cyanobacteria and eukaryotes derived from and trapped in rocks deposited prior to 2.0 Ga is consistent with early evolution of oxygenic photosynthesis and suggests that some aquatic settings had become sufficiently oxygenated for sterol biosynthesis by this time. The extraction of biomarker molecules from Palaeoproterozoic oil-bearing FIs thus establishes a new method, using low detection limits and system blank levels, to trace evolution through Earth's early history that avoids the potential contamination problems affecting shale-hosted hydrocarbons.Simon C.

4基于调度集合的多播单播数据联合调度算法显示文摘首先定义和分析了IEEE802.16e无线城域网中的一个新问题,即如何在保证移动终端服务质量的前提下,通过合理地调度终端的单播业务和多播业务来降低终端能耗.针对该问题,提出一种基于调度集合的联合调度算法(scheduling set based integrated scheduling,简称SSBIS).SSBIS算法将所有移动终端划分到多播调度集合或单播调度集合中,并利用多播数据的传输特点,在多播数据传输的相邻时隙内发送多播调度集合中所有终端的单播数据,而对于单播调度集合中的终端,则通过凸优化方法求得使终端休眠时间最长的单播业务调度方案,以达到降低终端能耗的目的.仿真实验显示,SSBIS算法在满足移动终端的最小数据速率要求的同时,可以明显地降低终端能耗.田霖 杨育波 方更法 石晶林 DUTKIEWICZ Eryk 2008软件学报2008,19,12:2
