张学林  丁树良  胡景春  段珊 《实验技术与管理》2011,28(5):54-57

对于粒子群优化算法(PSO)的研究内容涉及到许多方面。目前,针对PSO算法的研究大致可以分为算法的理论研究、算法的改进研究以及算法的应用研究。该文主要是对PSO算法的改进进行了研究,提出了一种带飞行时间因子的改进的粒子群优化算法(MPSO),并通过实验验证了MPSO优化性能较之PSO有了很大的提高。  相似文献   

萨冈的微笑与忧愁     

詹婷 《宜春师专学报》2011,(1):150-151

萨冈是法国当代文坛一位才情横溢的女作家,她以细腻的深刻的心理剖析、聪颖洒脱的手法、简洁清新的文风而备受法国年轻人青睐。她的笔下多为两人或三人的感情波澜,在平淡的字里行间透着一股淡淡的忧愁。在这种微笑背后隐藏着悠悠的浪子情怀究其根源就是一时间之伤。  相似文献   

基于Gabor核函数窗设置的图像识别     

熊娟  陈洪涛 《实验室研究与探索》2011,30(9):100-102,106

提出一种依据Gabor核函数窗的设置对红外图像进行识别,首先给出Gabor核函数窗的定义,分析核函数窗对红外图像识别卷积过程,给出了核函数窗的时窗和频窗,最后在对红外图像滤波识别时给出了最优核函数窗的计算方法。计算机仿真实验表明,只有在优化核函数窗设置设置情况下,才能取得了较好的识别结果。  相似文献   

Stabilization of Delayed Networks with Different Nodes     

徐君群  唐万生  张建雄 《天津大学学报(英文版)》2011,17(2):151-156

In this paper,the control of complex delayed networks with different nodes is proposed.Firstly,the stabilization of coupled networks with time delay is investigated.By constructing a Lyapunov function,a linear feedback controller design procedure for the networks is converted to the problem of solving a set of linear matrix inequalities.Then the results are extended to networks with both delayed dynamical nodes and delayed couplings.It is shown that the stabilization of complex networks is determined by the dynamics of each uncoupled node,coupling matrix and feedback gain matrix of networks.Two examples are simulated.In the first example,a network with 10 nodes consisting of Lorenz systems and systems proposed by Zhang in 2009 is given.It is found that the network states are divergent without control,and convergent under designed linear feedback controllers.In the second example,a larger network with 100 nodes consisting of delayed Chen systems and delayed Lorenz systems is given.The proposed method is also effective for large scale networks.  相似文献

我国自2009年实行的全日制专业学位硕士研究生教育正面临着严峻挑战。开展全日制专业学位硕士研究生教育的跟踪研究可为其顺利推进提供基础信息支持。本文在深入研究美国经验的基础上,提出了在我国开展全日制专业学位研究生培养过程跟踪研究的基本构想。  相似文献   

“物是人非”的哲学意蕴     

高欢欢 《湖北函授大学学报》2015,(11)

马克思的实践时空观强调人的实践活动在事物发展过程中的作用。当下,在人们的现实生活中常会有故地重游的经历,在故地重游的时候人们往往又会有物是人非的感叹或故地重游感慨多的情感经历。揭开这一微妙情感的面纱,不难发现人的实践活动是推动这一情感变化的主体。只是在这一情感形成的过程中时间,空间同人的活成交织状态发展着。  相似文献

Influence of sex and specialty on the prediction of middle-distance running performances using the Mercier et al.’s nomogram     

Jeremy B. Coquart  Daniel Mercier  Montassar Tabben  Laurent Bosquet 《Journal of sports sciences》2015,33(11):1124-1131

The aim was to test the influence of sex and specialty (3000, 5000 and 10000 m) on the validity of middle-distance running performance predictions obtained from the Mercier et al.’s nomogram. Consequently, we examined all official French track running rankings for the 3000-, 5000- and 10000-m events (men and women) from 2006 to 2012. A scoring table was used to determine the runners’ specialties. Only runners who performed in the three distance events within the same year were included (75 women and 400 men). The Mercier et al.’s nomogram was used to predict one running performance from the other two. The results showed no significant difference between actual and predicted running performances (P = 0.77). Female runners had significantly lower performances than male runners (P < 0.001). Specialty did not influence performances (P = 0.11). Very high correlations were found between actual and predicted performances (0.91 < r < 0.99), with the exception of women (r = 0.85) in 5000 m. Moreover, low limits of agreement were obtained for male and female runners, whatever the specialty. These results support the validity of the nomogram to predict running performance in the 3000-, 5000- and 10000-m events for male and female runners, whatever the specialty. The predicted running performances may be used in training programmes (e.g., to prescribe tempo runs) and competitions (e.g., to establish split times).  相似文献   

油酸三乙醇胺皂化物的合成     

甘黎明 《兰州石化职业技术学院学报》2015,(2):9-11

采用单因素控制变量法,以扣除酸值后的皂化值为评价指标,研究了反应配比、反应温度、反应时间对合成油酸三乙醇胺皂化物的影响。结果表明,油酸和三乙醇胺配比为1.2∶1(mol/mol)、温度为130℃、反应时间为3h时,反应达到平衡时体系中油酸三乙醇胺皂化物的含量最多。利用合成的油酸三乙醇胺皂化物调配成的水基润滑油符合相关要求。  相似文献   

论经验性的作者*--从神学诗学角度下的探讨     

陈于思 《楚雄师范学院学报》2015,(5)

神学诗学对文学的考察一直颇受学界的关注。从神学诗学中的时间概念入手,首先通过“经验性”这一特质来说明作者存在的局限性,然后引入“记忆”的概念着重探讨作者的经验性,最后通过对文学作品《追忆似水年华》中的经验性层面的呈现来更好地论证作者的经验性。对作者之为“经验性的人”的论证,有利于更好地去把握文本的内在意蕴。  相似文献
