同步动态随机存储器 合成孔径雷达 矩阵转置
2009/6/4
在分析同步动态随机存储器读写特性的基础上，提出了基于现场可编程门阵列的专用同步动态随机存储器控制器快速矩阵转置算法，实现了矩阵转置读写及顺序读写的等速与高效．该算法不仅充分地发挥了同步动态随机存储器的最佳矩阵转置读写性能，而且也提高了高分辨率合成孔径雷达成像处理的实时性．
基于CTM模型的多目标城市道路信号配时优化算法
细胞传输模型 交通仿真 交通控制 多目标优化
2010/9/27
采用了基于CTM模型对城市道路交叉口的交通流进行了建模，提出了该模型中各项交通流运行指标的计算方法。将CTM模型嵌入到多目标优化算法中，替代以往传统的目标函数计算方法,采用了非支配排序遗传算法NSGA II（None-dominated Sorted Genetic Algorithm II）进行多目标优化。通过算例分析不同输入条件和控制策略下的优化结果及与其他类似配时计算方法的比较，证明了此算法...
Upgrading photolysis in the p-TOMCAT CTM:model evaluation and assessment of the role of clouds
Upgrading photolysis p-TOMCAT CTM model evaluation assessment role of clouds
2010/2/5
A new version of the p-TOMCAT Chemical Transport Model (CTM) which includes an improved photolysis code, Fast-JX, is validated. Through offline testing we show that Fast-JX captures well the observed ...
Trends and inter-annual variability of methane emissions derived from 1979-1993 global CTM simulations
Trends and inter-annual variability methane emissions global CTM simulations
2009/3/10
The trend and interannual variability of methane sources are derived from multi-annual simulations of tropospheric photochemistry using a 3-D global chemistry-transport model. Our semi-inverse analysi...
The impact of air pollutant and methane emission controls on tropospheric ozone and radiative forcing: CTM calculations for the period 1990-2030
air pollutant methane emission tropospheric ozone CTM
2009/2/12
To explore the relationship between tropospheric ozone and radiative forcing with changing emissions, we compiled two sets of global scenarios for the emissions of the ozone precursors methane (CH4), ...

Mid-latitude ozone changes: studies with a 3-D CTM forced by ERA-40 analyses
Mid-latitude ozone 3-D CTM ERA-40
2008/12/9
We have used an off-line three-dimensional (3-D) chemical transport model (CTM) to study long-term changes in stratospheric O3. The model was run from 1977–2004 and forced by ECMWF ERA-40 and operatio...
