Abstract: 根据成像偏振探测中stokes参数图像获取的原理和方法,分析了传统求取stokes参数图像方法在保留图像细节信息和处理输入图像微小平移等方面的不足,在此基础上提出了基于自适应平移不变小波分解的stokes参数图像求取方法,并用无下采样的提升框架来执行平移不变小波分解以提高算法的灵活性和计算速度.针对不同的stokes参数图像求取方法,用均值、方差、熵、边界能量对融合结果进行评价和分析.通过仿真,表明本文方法提高了stokes参数图像的质量并改善了stokes参数图像计算方法对输入图像平移的敏感性。

Framework of reservation and QoS monitoring of resource based on WS-Agreement
基于WS-Agreement的资源预留与QoS监控框架

Abstract: 目前还没有遵循OGSA/WSRF规范的网格服务中间件能够很好地支持基于QoS协商的网格资源管理,因此重点研究了如何设计一个执行服务级协定(SLA)的框架,能够在网格中协商资源预留和任务执行期间对所在资源的QoS监控.首先通过定义资源预留的XML Schema,使得资源请求者和提供者基于WS-Agreement能够协商包含关于资源预留的协定;然后遵循WSRF及WS-*规范设计和开发出一组Web服务用于构建一个基于WS-Agreement的资源预留与QoS监控框架(RMF),并将其集成到Globus资源管理模型中;最后通过理论分析和模拟实验评估了RMF的综合性能.

Abstract: The influences of inertia, elastic-plastic effect and initial void size are studied on the damage evolution in spallation of ductile metals under planar impact loading by using the hollow spheroid model. Numerical analysis indicates that inertia, elastic-plastic effect and initial void size each have a significant influence. Influence of Initial damage or initial void size on spallation damage cannot be neglected. In this paper we attempt to develop a method to analyse initial void size due to its importance on spallation damage.
A Productivity Prediction Equation Considering Rock PermeabilityStress-Sensitivity in Low-Permeability Gas Reservoirs
考虑渗透率应力敏感的低渗气藏产能预测公式

Abstract: Pore pressure decreases, effective stress increases, and permeability declines due to matrix and pore compression as gas produces in low-permeability gas reservoirs. This affects the deliverability of lowpermeability gas reservoirs. Based on Darcy flow law and the universal cognition that the rock permeability varies with the effective stress exponentially, this paper presents a new equation considering rock permeability stress-sensitivity for estimating the productivity in low-permeability gas reservoirs. A ease calculation with this new equation shows that considering permeability stress-sensitivity in the prediction is necessary, especially for the high stress-sensitive low-permeability gas reservoirs, and this will provide necessary reference to determining reasonable producing pressure drop and producing rate.

Simulated Responses of SST to Westerly Wind Bursts in the Western Equatorial Pacific Warm Pool
一个大洋环流模式中赤道西太平洋暖池海面温度对西风爆发的响应

Abstract: 用逐日的欧洲中期数值预报中心再分析(ERA)风应力,和由Haney公式结合ERA海表资料与预报海温计算出的热通量强迫一个全球大洋环流模式.并用逐日的模拟结果与TOGA-COARE(Tropical Ocean--Global Atmosphere--Coupled Ocean-AtmosphereResponse Experiment)浮标观测资料对比,分析模拟结果中暖池海区上层海洋热量平衡对西风爆发(WWB)的响应.在第一次WWB过程中,模拟与观测的主要差异在WWB期间,而造成差异的原因主要是模式中由下沉运动引起的增温和由强的纬向温度梯度引起的暖平流.初步认为下沉增温可能是差分格式本身和模式分辨率不足造成的.从热量平衡的结果看,第二次WWB事件的模拟比第一次更成功,两次差异可能与两次WWB事件的季节背景不同有关.

IAP/LASG海洋环流模式对风应力的响应

Yu Yongqiang,Zhang Xuehopng,Guo Yufu,Antoine Izard,<br>俞永,,郭裕福,Antoine Izard
大气科学 , 2001,
Abstract: 为了检验第三代IAP/LASG全球海洋环流模式在模拟20世纪80年代热带太平洋年际变化方面特别是ElNino和LaNina事件的能力,作者使用了三种风应力资料强迫该模式.然后,将模拟的海温同NCEP海洋同化资料相比较.分析表明,在赤道附近,模式对风应力的响应在SST分布、温跃层的描绘以及突出E1Nino和LaNina事件方面同NCEP海洋同化资料有许多共同点.然而,在描绘l0°N以北和l0°S以南的SST异常以及描写季节循环方面,响应是不够精确的.另外,模拟的温度异常滞后于NCEP海洋同化数据两个月左右.

Study of Adaptive Multi-band Polarization Image Fusion
自适应多波段偏振图像融合研究

ZHAO Yong-qiang,PAN Quan,ZHANG Hong-cai,<br>赵永,潘泉,
光子学报 , 2007,
Abstract: To remove the clutter efficiently and detect the objects accurately,the information presented by multi-band polarization images should be combined.An adaptive weighting multi-band polarization images fusion method is proposed based on the false color mapping and the degree of linear polarization entropy to combine the information.The characters of object and background and the principles of multi-band imaging polarization are used in this method.At the same time,the relation between objects' spectral and polarization information,the information difference contained in polarization images in different band,the relations among Stokes' images in same band,and the information relation between object and background in the degree of linear polarization(DoLP) image are all used in this method.The background clutter is removed through combing Stokes'images and DoLP image in different band.In final simulation,this fusion method is used in different multi-band polarization images,the fusion results and evaluation index show that the background is removed efficiently.
