基于Diviner红外亮温数据的月球赤道地区温度廓线模拟  [PDF]
冉真,王振占

Abstract: ?以Diviner红外亮温数据为基础,结合半有限固体的热传导模型,模拟了月壤温度廓线并分析了影响月壤温度廓线的三种因素,为“嫦娥”卫星微波探测仪数据稳定性分析提供可靠依据.利用Diviner通道7红外亮温反演月表温度,代替月表辐射热平衡模型求解月表温度的过程,减少了由于辐射热平衡模型中月表太阳辐照度理想假设引起的误差.通过月壤逐层迭代10000次月球昼夜周期,月球赤道地区6.0m深月壤底面温度趋于246K,与以表面辐射热平衡为条件的底面温度模拟值250K近似.基于Diviner实测数据的月表温度与辐射热平衡模型模拟月表温度对比结果为:赤道地区Diviner实测表面温度比模拟值差异主要分布在月球白天,在受月表地形起伏影响较大的月球昼夜交替的时间段更为显著,约50K:在月球夜晚,两者差异约2K.利用Diviner数据与热传导模型模拟得到的月壤温度廓线可当作月壤温度廓线的真实值,作为进一步分析“嫦娥一号/二号”微波探测仪数据的依据.

Abstract: L波段风廓线雷达采用相干累积技术提高雷达探测灵敏度,用于对降水云体垂直探测,能获取高分辨率的云体返回信号的全谱信息。应用它对2009年5月14日层状云降水过程中出现的零度层亮带进行了连续探测研究,得到零度层亮带附近区域中返回信号的谱参数(功率、平均多普勒速度、速度谱宽)和回波功率谱密度分布随高度的变化和演变特征。在零度层亮带区附近质点的冰水转化过程中,云体中大部分冰晶、雪花从-1.3℃附近开始表面融化,0.8℃附近冰晶、雪花的整体冰框架开始破碎分离成尺度较小的液态降水质点,3.5℃附近冰晶、雪花全部融化为液态降水质点。同时,在0.8℃附近约300m厚度的层次中观测到回波强度谱区范围突然展宽现象,这反映出降水质点的冰水转化引起局部环境强烈降温可能导致出现少量的细部对流现象。

Abstract: A comparison of data detected by wind profiler and balloon-mounted radars revealed no significant differences between the two types under conditions of weak wind power. The variation rules of space and time were studied by using the data of wind profiler radar at the seaside of Huilai. The results show that the wind profiler radar has stronger detecting capability on the vertical structure of three-dimensional winds and can detect sea-land breeze vertical shear in real time. Such data could be used to analyze the rules of pollutant diffusion and migration in coastal areas. In addition, data obtained by the wind profiler radar was studied to determine the rule of periphery wind shear of Typhoon Chanthu. The results show that the wind profiler radar also has stronger detecting capability on the typhoon peripheral sinking airflow area of high-altitude wind in a three-dimensional wind vertical structure. Moreover, this type of radar can detect the rules of typhoon space shear in real time to improve the efficiency of the typhoon prevention in coastal areas.

Abstract: 为了能在静止气象卫星上实现微波被动遥感探测大气温度廓线,并保持一定的地面空间分辨率(如视场小于60km),就需要使用高频微波及大天线.欧洲和美国下一代静止气象卫星上都已考虑采用118.75GHz附近通道.为了充分了解118.75GHz附近通道遥感反演温度廓线的能力,为仪器研制及今后资料的解释反演提供必要的基础数据,作者开展了采用118.75GHz附近六个通道遥感反演大气温度廓线的数值模拟研究.统计反演的数值试验表明,118.75GHz附近六通道对温度垂直分布有一定的遥感反演能力;温度反演较好的层次对应于权重函数峰值所在的位置.

Abstract: Using the conventional sounding data at Beijing meteorological station(ID:54511) during May to September in 2007 and 2008, the reliability of quantitative applications of the sounding constructed from the temperature and humidity data detected by microwave radiometer and the wind data obtained by wind profiler(hereinafter referred to as special sounding) at the same station was analyzed. Results showed that the special and conventional sounding had a more consistent trend of any element, since the special s...
A Call-Graph Profiler for GNU Octave  [PDF]
Muthiah Annamalai,Leela Velusamy
Computer Science , 2008,
Abstract: We report the design and implementation of a call-graph profiler for GNU Octave, a numerical computing platform. GNU Octave simplifies matrix computation for use in modeling or simulation. Our work provides a call-graph profiler, which is an improvement on the flat profiler. We elaborate design constraints of building a profiler for numerical computation, and benchmark the profiler by comparing it to the rudimentary timer start-stop (tic-toc) measurements, for a similar set of programs. The profiler code provides clean interfaces to internals of GNU Octave, for other (newer) profiling tools on GNU Octave.

Real-Time Software Profiler for Embedded Systems  [PDF]
Medhat Hussein Ahmed Awadalla,Kareem Ezz El-Deen
International Journal of Soft Computing & Engineering , 2013,
Abstract: Embedded systems are a mixture of software running on a microprocessor and application-specific hardware. There are many co-design methodologies that are used to design embedded systems. One of them is Hardware/Software co-design methodology which requires an appropriate profiler to detect the software portions that contribute to a large percentage of program execution and cause performance bottleneck. Detecting these software portions improves the system efficiency where these portions are either reprogrammed to eliminate the performance bottleneck or moved to the hardware domain gaining the advantages of this domain. There are profiling tools used to profile software programs such as GNU Gprof profiler. GNU Gprof integrates an extra code with the software program to be profiled causing inaccurate results and a significant execution time overhead. To address these issues, this paper proposes a software profiler called AddressTracer that is accurately able to evaluate performance matrices of any specific software portion. A set of benchmarks, Dijkstra, Secure Hash Algorithm, and Bitcount are profiled using AddressTracer, Airwolf and GNU software profiling tool (Gprof), for a quantitative comparison. The achieved results show that AddressTracer gives accurate profiling results compared to Gprof and Airwolf profilers. AddressTracer provides up to 50.15% improvement in accuracy of profiling software compared to Gprof and 6.89% compared to Airwolf. Furthermore, AddressTracer is a non-intrusive profiler which does not cause any performance overhead.
