毛管压力曲线表征了储层岩石孔喉大小和分布,对于孔隙性储层而言,岩石绝对渗透率主要取决于孔喉分布。通过对来自吐哈、辽河、胜利、四川德阳新场气田等油气田不同砂岩储层岩样393个陕甘宁中部气田及加拿大等地区的碳酸盐岩储层岩样257个的压汞毛管压力数据的研究发现,双对数坐标下储层岩石毛管压力曲线呈明显的双曲线特征,用可用双曲线的两条渐近线Pd和Sb及孔喉几何因子（Fg)三个参数唯一确定,双曲线的顶点代表了非润湿相在岩石系统中完全占据能有效控制流体流动的那部分有效孔隙空间时的状态;双曲线的位置形状参数或顶点参数决定了岩石绝对渗透率的大小。文中分别用位置形状参数和顶点参数成功建立了砂岩储层和孔隙性碳酸盐储层的岩石绝对渗透率估算模型,并用大量实测数据验证了估算模型的可靠性。

多传感器网络系统基于无序估计的分布式信息融合

无线传感器网络的局部节点往融合中心传输信息时,不确定的随机延迟易使得信息无序现象频繁发生,从而导致传统信息融合方法的应用面临诸多难题和挑战。该文以带有任意随机延迟的多传感器同步采样系统为对象,研究无序估计(“Out-Of-Sequence” Estimate, OOSE)信息系统的最优分布式融合问题,最终建立一种新型的通用最优OOSE融合算法。与现有基于集中式框架的无序量测融合方法相比,新算法在融合精度和算法复杂度上均具有显著优势。算法分析和计算机仿真验证了新算法的有效性和优越性。     

Health-related vocabulary knowledge among deaf adults.

Background: Many deaf individuals are at increased risk for fund-of-information deficits, including deficits in health-related information. Research on health information knowledge, an aspect of health literacy, demonstrates an association between low health literacy and health disparities in many populations. Deaf individuals are at particular risk for low health literacy, but no research has been conducted on this topic. Objective: To investigate health-related vocabulary knowledge in a sample of deaf adults. Measure: A task based on the Rapid Estimate of Adult Literacy in Medicine (REALM). Participants: Fifty-seven deaf adults reported whether they did or did not comprehend 66 health-related terms from the REALM. Of the participants, 81% possessed a college degree. Results: Thirty-two percent of the deaf participants earned scores on the modified REALM task comparable to REALM scores considered indicative of low health literacy. The pattern of words that were least commonly and most commonly understood differed from normative expectations of hearing REALM respondents. Conclusions: This highly educated deaf participant sample demonstrated risk for low health literacy. The general deaf population is likely at even higher risk for health problems associated with low health literacy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

火灾中火场运动方向估计方法研究

研究火灾中火焰运动方向估计问题。针对火灾现场,燃烧中的火焰存在着动态特征不定,运动方向容易发生随机性改变,影响估计的准确性。传统的物体运动方向估计方法很难对燃烧的火焰做出准确的方向估计。为解决上述问题,提出基于运动能量块计算的火焰运动方向判定方法,首先为燃烧的火焰建立运动能量块,创立火焰的动态特性,通过预判火焰运动块的方向,形成运动块在各个方向上的匹配,完成对火焰燃烧过程中,运动方向的准确估计。仿真结果证明,改进方法能对燃烧中的火焰运动方向做出准确估计,取得了满意的效果。     

Effects of Different Spatial Resolution of Remote SensingImages on Estimation Accuracy of Urban Building Height

In this study,the remote sensing images of WorldView-2,GF-2,and GF-1,which cover Xiamen Software Park,were selected for study.A building and shadow extraction process suitable for different images was constructed,which applied object\|oriented approach and morphology ideas combined with spectral,shadow and shape constraints.Subsequently,the building heights of three different spatial resolutions of 0.5 m,1 m and 2 m were estimated by using the shadow length estimation method.Finally,the influence of image spatial resolution on building extraction accuracy and building height estimation accuracy was evaluated quantitatively.The main conclusions are as follows：(1) The improved building and shadow extraction process achieves higher extraction accuracy,but accuracy decreases slightly with the decrease of spatial resolution of images;(2) With the decrease of spatial resolution,the accuracy of building height estimation decreases gradually,but it does not show linear relationship.At the resolution increases from 1m to 0.5 m,the accuracy of building height estimation increases faster than the resolution increases from 2 m to 1 m;(3) GF-1 is more suitable for height estimation of high\|rise buildings and GF-2 is suitable for middle and high rise buildings,while WorldView\|2 has higher estimation accuracy for building height in different height ranges.
