Unmanned aerial vehicles swarm conflict based on multi-agent system

本文将多agent系统引入到大规模无人机集群对抗决策系统中,给出了基于多agent系统的大规模无人机集群对抗决策方法.将机群中的每个无人机视为一个独立agent,建立了无人机运动模型,为无人机设计了独立的个体行为集,并针对每种行为给出了决策方法.通过每个个体无人机对其邻域环境的作用,涌现出宏观的集群对抗(作战)效果.使用MATLAB仿真软件对所设计的大规模无人机集群对抗方法进行了仿真,验证了所设计的基于多agent系统的大规模无人机集群对抗决策方法的有效性.The multi-agent system theory is employed to build the maneuvering decision-making model for large-scale unmanned aerial vehicle(UAV) swarm conflict. In this model, each UAV in the swarm is regarded as one independent agent. With the establishment of UAV motion equation, individual behavior set and action criterion, each UAV keeps on interacting with its neighboring environment and the UAV swarm conflict outcome emerges eventually from such a process. Simulation experiments are conducted using MATLAB and the results demonstrate the effectiveness of the built decision-making model for UAV swarm conflict.航空科学基金项目(20140168001)资助~

基于MSP430F149的空间矢量脉宽调制波的实现

提出了一种基于MSP430f149微控制器的空间矢量脉宽调制波的实现方案。它采用查表法调节矩形波占空比的变化,从而实现三相交流异步电机的变频调速。该方法算法简单,实时计算量小且易于数字化实现,在通用16位微处理器上即可完成。文章从原理的阐述,数据链的取值,硬件电路的设计等方面对以上方案进行了具体详细的说明

In order to change the secondary vegetation status on the coast, the remnant forest and shrub should be protected strengtheningly. And the coastal protection forest system should be constructed on the basis of coastal psammophilous vegetation, thus to improve the environment condition and effectiveness against natural disasters.海洋公益性行业科研专项(200905008

补骨颗粒含药血清对大鼠软骨细胞凋亡及Trx2信号通路的影响

目的观察补骨颗粒含药血清对体外培养的大鼠膝关节软骨细胞凋亡及对Trx2、ASK1及Caspase3表达的影响,从而探讨补骨颗粒预防骨性关节炎发生发展的作用机制。方法采用两步酶消化法分离培养大鼠软骨细胞,并进行传代培养。应用膜联蛋白V-FITC/PI染色后经流式细胞仪检测软骨细胞的凋亡情况。同时,通过电泳分离蛋白并通过蛋白质印迹分析Trx2、ASK1及Caspase3的表达情况。结果软骨细胞培养15 d左右铺满80%～90%的培养皿,大部分细胞呈梭形。流式细胞检测结果显示空白血清组的细胞凋亡率为22.80%,明显高于含药血清组(P<0.05),而20%含药血清组(15.91%)与30%含药血清组(17.93%)的细胞凋亡率又明显低于10%含药血清组(21.58%),各组间比较差异具有统计学意义(P<0.05)。蛋白质印迹分析结果显示含药血清组Trx2的表达量都明显增多,以10%含药血清组的表达量最多;空白组与10%含药血清组的ASK1与Caspase3的表达量比20%与30%含药血清组多。结论补骨颗粒可以通过激活Trx2信号通路而抑制软骨细胞的凋亡,从而起到预防骨性关节炎发生发展的作用

Relation between soil salinity in intertidal zone and electric conductivity

以5∶1的水土质量比浸提潮间带土壤,质量法测定的土壤盐度(质量分数),与电导法测定的稀释了5倍的土壤浸提液(5∶1水土质量比)的电导率值之间有极显著的相关性。质量法实测的土壤盐度与电导率计算的土壤盐度之间的相对误差多在5%以下。因此,用电导法测定潮间带土壤盐度不失为一种简便、快速的方法,尤其是样品数较多时更可节约时间。 【英文摘要】 There was significantly correlation between soil salinity in intertidal zone obtained by mass method (the ratio of mass of water to soil is 5∶1) and electric conductivity of extracting solution diluted five times by electric conductivity method The relative errors were almost below 5% between soil salinity measured by the mass method and the ones calculated by electric conductivity. So, electric conductivity method is a simple and rapid method for measurement of soil salinity in intertidal zone after defini...国家自然科学基金项目(30270272

Effect of salinity on microbial densities of soil in the dilution plate technique applied in mangrove areas

The effects of salinity on soil microbial counting from the samples in mangrove areas in Jiulongjiang Estuary of Fujian, and Futian Mangrove Nature Reserve of Shenzhen, China, were tested by dilution p late technique. The results showed that the soil microbial densities in mangroves and mudflat were significantly influenced by the salinity of dilution water and agarmedia. For the bacteria, the seawater served as sterilized dilution water was significantly ( P < 0. 05) more benefic to the enumeration on the p lates than the freshwater, but in reverse for the actinomycetes and fungi. The increasing salinity of media within 35 significantly decreased microbial colonies on the p lates, especially for the actinomycetes, in sp ite of the fact that the effect of salinity ofmedia on fungal numberswas not indefinite. The bacterial colonieswere more abundant on the agar p lates with low salinity than with high salinity or without any NaCl. It was p roposed that some methodological imp rovements were needed when the dilution p late technique was app lied to microbial counting in the samp les of mangrove forest and mudflat at the same tidal level in inter2tidal zone. The sterilized dilution water should be p repared with seawater for the bacteria, but with freshwater or low saline water for the actinomycetes and fungi. The salinity of agarmedia should be low for the microbial isolation and enumeration of soil samples from the mangrove areas including mudflats.国家自然科学基金资助项目(30270272
