Multiple Background Model-Based Moving Target Detection on Sea Surface

提出一种在反射光较强的条件下基于多背景模型的海面运动目标检测方法.使用基于统计模型的变化检测方法将被监控场景区分为海浪波动显著的背景区域和海浪波动不显著的背景区域;对这两种区域中的像素点分别以Weibull分布模型和Gauss分布模型建立背景模型;使用建立的背景模型检测海面的运动目标.实验结果表明,在海面反射光较强且波浪波动较大的情况下,用该方法可以比较准确地检测到海面的运动目标. A new method based on multiple background model for moving target detection on the sea surface is proposed. It can detect the moving target on the sea surface when there is heavy sea clutter and the reflected light is strong. The monitored area is first partitioned into two regions using the statistical model-based change detection method, where the sea clutter in one region is heavier than the other. Then Weibull distribution is used to create the background model for pixels in the region having heavier sea clutter and Gaussian distribution is used for the other region. Finally the background model is used to detect moving target on the sea surface. Experimental results show that the proposed method can detect moving target effectively even when the sea clutter is heavy and the reflected light is strong.国家自然科学基金资助项目(60175008);; 国家创新研究群体项目(60024301

IL-20及其受体在大鼠自身免疫性心肌炎不同阶段的表达

目的探讨IL-20及其受体在大鼠实验性自身免疫性心肌炎(EAM)急慢性期各阶段的表达。方法将提纯精制后的猪心室肌球蛋白加等体积含结核杆菌H37Ra株的完全弗氏佐剂充分混合,于Lewis大鼠双后足皮下注射制作大鼠EAM模型;将15只大鼠按随机数字表法分成3组,每组5只,分别于3、6、12周后处死取心肌组织进行检测。另取5只大鼠注射0.9%氯化钠注射液作为对照组。HE染色评估EAM急慢性期各时点心肌损伤程度;应用实时荧光定量RT-PCR检测IL-20及其受体链(IL-20R1/R2,IL-22R1)在各时点的mRNA表达;应用Western blotting法检测IL-20在各时点的蛋白表达。并以ELISA检测不同时点心肌组织匀浆IL-20蛋白含量[IL-20蛋白/总蛋白(pg/ng)]。结果 IL-20在EAM急性期3周时表达逐渐升高,6周时达峰值,12周时又逐渐减少。IL-20的组织蛋白水平与基因表达相一致。结论 IL-20可能参与大鼠EAM的疾病过程,并且可能在EAM的晚期炎症及慢性心肌纤维化的机制中起重要作用

Energy Efficiency Evaluation of Frozen Food Production Factories

At present, food production factories in our country evaluate energy consumption level by using energy consumption per unit production or energy consumption fees. However, these indices do not reflect the influence of the using level, business level, and the quality level on the enterprise energy efficiency. In this study, energy consumption situation of some food production factories at home and abroad were compared, and the problems caused by the current energy consumption evaluation indices were analyzed. A new energy efficiency evaluation index which can reflect using level, business level, and the quality level was proposed. Then the evaluation of energy efficiency for six representative domestic food production factories was performed with the present index. The result shows that energy efficiency difference among factories is obvious

Dynamics of nutrient and energy for fine roots of Casuarina equisetifolia plantations on coastal sandy soil

2005年1月到2005年11月对福建省惠安县赤湖林场不同林龄木麻黄人工林细根养分和能量的季节动态进行了观测,结果表明:(1)6种元素的含量在不同林龄木麻黄细根中都具有明显的季节变化。各林龄细根的N含量一般在冬夏季节较高,且死细根的N浓度高于相同林龄的活细根,除12林龄活细根P浓度在7月份有最大值外,其他各林龄活、死细根在一年中呈波动性下降,K含量在冬季较高,而在其他季节变化幅度不大,除5林龄活细根和18林龄死细根在3月份和7月份有两个峰值外,其他林龄细根Ca含量随季节变化较小,Mg含量随季节变化总体呈下降趋势,而在11月份上升;各林龄C则呈波浪形变化;(2)随着林龄的增大,细根N、P、Mg含量的变化模式相似,都呈先增加,后降低,再增加的趋势,K和Ca含量变化趋势相似,但变动幅度存在差别,C则呈波浪形变化;(3)随着季节的变化,灰分、干重热值和去灰分热值呈"V"形变动,一年中都存在两个峰值,分别在3月份和7月份或9月份;(4)灰分、干重热值和去灰分热值随林龄的增大表现为波浪形增加。由此可见,不同森林类型的细根养分和能量动态具有季节和林龄的特殊性,在进行整个地区森林生态系统物质循环和能量流动研究时,应考虑不同森林类型的特性。The seasonal dynamics of nutrient and energy of fine roots in C.equisetifolia plantations of different ages was studied at Chihu forestry farm of Hui'an county,Fujian province from January to November in 2005.We obtained the following results:(1)There was significant seasonal dynamics of six elements in the fine roots of different aged C.equisetifolia plantations.N concentration of dead fine roots was higher than that of living fine roots,and was relatively higher in summer and winter.P concentration of fine roots fluctuated with a decreasing trend except for the living fine roots of 12 year-old plantation.K concentration was higher in winter than in the other seasons.The highest Ca concentration in March and July was found in living fine roots of 5 year-old plantation and dead fine roots of 18 year-old plantation,while Ca concentration remained little change for other aged plantations.Mg concentration decreased from January to September and then increased in November.C content fluctuated with time.(2)The similar trend was found for N,P and Mg;and for K and Ca,respectively;C concentration fluctuated with plantation age.(3)The ash content,gross caloric values and ash free caloric values changed with "V" type,and were relatively high in March and July or September,respectively.(4)The ash content,gross caloric values and ash free caloric values tended to increase with the increasing plantation age.It was concluded that the nutrient and energy dynamics of fine roots varied with seasons and plantation ages.To discuss matter cycling and energy flow of forest ecosystems,we should pay attention to these characteristics of different stands.国家“十一五”科技支撑计划资助项目(2006BAB03A14-01);; 福建省科技重大资助项目(2006NZ001-2);; 国家林业局南方山地用材林培育重点实验室资助项目~
