    本文利用第三代海浪模式SWAN基于非结构三角形网格和矩形网格分别对1319号“天兔”、1323号“菲特”两场台风影响下的福建沿岸有效波高进行了数值模拟。其中,福建中部A海堤的三角形网格模拟的平均绝对误差分别为0.15m、0.16m,而矩形网格的平均绝对误差分别为0.23m、0.22m;三角形网格模拟的均方根误差分别为0.19m、0.20m,而矩形网格的均方根误差分别为0.26m、0.28m,说明两种网格的模拟值与实测值较吻合。然而三角形网格的模拟效果更好一些。这说明,本文建立的基于精细化三角形网格的福建沿岸海浪数值模型可作为预报模型用于业务预报。 有了海浪数值预报模型,本文进而建立了福建中部...In this paper, the third generation wave model SWAN which is based on unstructured triangular and rectangular mesh is used to simulate respectively the significant wave height during 2 typhoons (1319 Usagi and 1323 Fitow) along Fujian Coast.

    近两年来,改编自已有文本的IP电影逐渐成为中国电影界最为热门的话题。电影从业者对IP电影趋之如骛,电影观众也对IP电影给予高度关注。数不胜数的IP电影雨后春笋般在中国电影市场中出现,它们既能在票房领域呼风唤雨,又能收获其他类型电影难以企及的关注度。不过IP电影在引发关注的同时也引发着争议,关于IP电影的批评声与日俱增。IP电影在快速发展过程中出现的问题日渐突显,这导致IP电影的发展也进入了瓶颈期。本文将通过对IP电影发展现状的观察,分析IP电影在发展过程中存在的种种问题和误区,并探索性地为IP电影的可持续发展提出对策与建议。 本文主要包括五个部分。第一部分是对IP电影现状的分析,包括IP电影...Recently, IP Movie which derives from existing artistic material has gradually become one of the most popular topics in Chinese film industry. Both filmmakers and movie audiences have been showing great enthusiasm in IP Movie. Many IP Movies have managed to gain impressive box-office incomes and attentions which the other kinds of movies would never achieve. But IP Movie has also caused increasing...学位:艺术硕士院系专业:人文学院_艺术学学号:1022014115238

    Study on melting curve analysis for genotyping

    熔解曲线分析法(Meltingcurveanalysis)是一种PCR后产物分析技术,具有操作简单、结果判断直观等特点,已经被广泛用于突变扫描、甲基化检测等研究。熔解曲线分析技术可分为探针熔解曲线(Probemeltingcurve)和荧光染料熔解曲线(Fluorescentdyemeltingcurve)两大类。探针熔解曲线利用探针与不同的靶序列杂交后形成的双链DNA熔点(Meltingtemperature,Tm)的差异来区分不同的靶序列,是实现多重实时检测的重要途径之一。但难点在于探针设计和如何使一条探针能同时高效率结合多种靶序列,并且具有多个可区分的熔点峰;荧光染料熔解曲线无需探针设计...Melting curve analysis is a straightforward, simple and widely-used PCR methed for genotyping and methylation. Melting curve analysis for multiplex PCR detection can be divided as: (1) probe and (2) fluorescent dye melting curve. Probe melting curve is used of single probe to difference target sequence forming different double-stranded DNA with distinguisheable melting temp...学位:理学硕士院系专业:生物医学研究院_化学生物学学号:3052008115271

    Based on Luo Zhenyu’s academic works, this article sorts out the works related to calligraphy from four aspects: Oracle bones, Dunhuang studies, sigillography and calligraphy. The paper discusses the relationship between Luo Zhenyu’s academic and calligraphy based on a macroscopic grasp of his academic system with the aim of providing more ideas for the study of Luo Zhenyu’s calligraphy. The collation of his academic works not only supplements the materials on research on Luo Zhenyu’s calligraphy, but also provides a better foothold for the advance of research on Luo Zhenyu’s calligraphy.陶徳民教授古稀記念

    针对区间直觉模糊集(IVIfS)的聚类问题,提出了基于IVIfS的C均值聚类算法。算法首先应用IVIfS的欧氏距离,构造了聚类的目标函数;然后根据拉格朗日乘数法推导出聚类的迭代公式,得到IVIfS聚类算法;此外,还提出一种IVIfS聚类的有效性函数,并将此函数和聚类结合,给出可以确定最佳聚类类别数的聚类流程;最后通过实验验证了该算法不仅得到了最佳聚类类别数,同时还提高了聚类的准确率。Aiming at the clustering problems of IVIFS,the C-means clustering algorithm based on IVIFS is proposed.By means of the Euclidian distance,the objective function of clustering is constructed.Next the iterative formula is deduced according to Lagrange multiplier method,then IVIFS clustering algorithm is obtained.Moreover an IVIFS clustering validity function is defined to confirm the best clustering class number's clustering procedure.Finally,experiment results show that the method can not only acquire the best class number,but also improve clustering accuracy.福建省自然科学基金(2010J01362);厦门大学国家“211”(三期):立体通信和信息集成智能技
