Design and Implementation of Web Teaching Assistant System

网络技术的高速发展，使人类的信息资源实现了高度共享，并从根本上改变了人类进行信息交流的方式，对高等教育的影响也必将是深刻的。从大的方面来说，它对高等教育的管理模式、教学模式、财政投入模式等都要带来巨大的影响，从小的方面来说，它可以解决传统课堂教学中存在的很多问题，过去一些不可能实现或很难实现的教学设计思想，现在就可以实现了。 首先，网络给教学工作确实带来了极大的方便。师生可以随时通过email交流，或通过网络讨论。给他们提供一个更好的网络辅助教学系统就成为比较迫切的问题。 其次，可以更好的实现许多教学设计策略。网络辅助教学在给教学工作带来极大方便的同时，也使原来不太好实现或不可能实现的教学...Rapid development of internet technology makes the information highly shared and changes the way people communicates with information. The effects on higher education are certainly profound. From larger aspects, it could bring huge influence to the management model, teaching model, financial input model. From smaller aspects, it could solve many issues which existed in traditional classes. Those t...学位：工程硕士院系专业：软件学院_工程硕士(软件工程)学号：X200823002

The Method of A-Harmonic Approximation and Optimal Interior Partial Regularity for Nonlinear Elliptic Systems Under Controllable Growth Conditions

考虑具有可控增长条件的非线性椭圆方程组弱解的部分正则性.利用Duzaar和Grotowski引进的弱解部分正则性证明的新方法,该方法是建立在调和逼近技巧一般形式的基础上的,我们把前人的结果由自然增长条件推广到了可控增长条件,并且所得到的弱解导数的Hlder指标是最优的.In this paper,we consider the nonlinear elliptic systems under the controllable growth condition.We use a new method introduced by Duzaar and Grotowski,for proving partial regularity for weak solutions,based on a generalization of the technique of harmonic approximation.We extend previous partial regularity results under the natural growth condition to the case of the controllable growth condition,and establishing the optimal Hlder exponent for the derivative of a weak solution directly.Supported by NSF(No:10531020)of China and the Program of 985 Innovatio Engineering on Information in Xiamen University(2004-2007

互联网金融的发展逻辑——基于金融与互联网功能耦合的视角

作为新常态调整下发展起来的全新的金融业态,互联网金融给以商业银行为代表的传统金融体系带来了不小的冲击,这是金融发展意料之外也是结构调整下情理之中的结果。如何把握互联网金融的发展逻辑,破解存在的掣肘,进而引领其健康发展？本文从互联网金融的内涵与表现形式入手,运用相关金融基础理论,以金融与互联网功能耦合的视角为切入点,力图从整体角度把握其发展逻辑,并提出互联网金融发展的立体框架展望。教育部人文社会科学研究青年基金项目“中国式分权下的地方政府质量提升路径研究”(12CJL022)阶段性成

Species composition in genus Scylla from the coast of southeast China

【中文摘要】 为调查青蟹属在中国大陆东南沿海的种类组成及明确优势种的种类,采集了13个地区共413只青蟹。通过形态比较,确认有4个种,它们是:锯缘青蟹(Scylla serrata),紫螯青蟹(Scylla tranquebarica),拟穴青蟹(Scylla paramamosain),榄绿青蟹(Scylla olivacea)。这4个种类可以从头胸甲额缘4齿的长度(FMSH/DFMS)、形状,螯足腕节内刺的有无、螯足及步足斑纹来区分。其中拟穴青蟹在中国大陆东南沿海分布最广,数量最多,其他3个种仅在海南和北部湾被发现。在拟穴青蟹中有9.7%的成熟个体和33.3%未成熟个体具有螯足内刺,因此不能仅凭借这个特征来鉴别拟穴青蟹。本文对青蟹属4个种的特征进行了描述并编制分种检索表。 【英文摘要】 There has been argument on dominant species and the species composition in the coast of southeast China in genus Scylla.413 individuals were collected from 13 sites and took 24 measurements with vernier calipers to the nearest 0.1 mm.By morphological comparison,there are 4 species being classified,namely Scylla serrata,Scylla tranquebarica,Scylla paramamosain,Scylla olivacea.The four species can be distinguished from the length and shape of the four frontal spines,with or without inner carpus spine and the ...福建省重中之重项目“福建省海洋生物优良种质和生物活性物质的应用基础研究”; 国家自然科学基金项目(40376044

Improved Method for Fuzzy C-Means Clustering Algorithm

由于传统的模糊C均值(fuzzy C-MEAnS,fCM)算法没有考虑像素点的空间邻域信息,仅涉及像素的单点灰度,在处理含有噪声的图像时有很大的局限性,因此分割效果较差。针对fCM的缺陷,提出一种新的改进算法,该算法引入gIbbS随机场,将gIbbS随机场先验概率与像素点隶属度的乘积作为新的像素隶属度。实验表明,改进后的算法有良好的分割效果,既可以较为完整地保留图像边界细节,又能较好地去除图像的噪声。The traditional fuzzy C-means (FCM) algorithm has great limitations in dealing with the noisy images owing to not considering the spatial information of the pixels and only involving the pixel gray of a single point,so it's poor in segmenting an image.For the defects of the FCM algorithm,a new improved algorithm is proposed in this article,in which a product of Gibbs priori probability and the membership is regarded as the new pixel membership.Experimental results show that the improved algorithm has a good segmentation result;it can retain more complete edge details of image and can remove the image noise more effectively.南京军区重点项目(项目编号:11Z023); 福建省自然科学基金项目(项目编号:2008J0312

Fast local binary fitting optimization approach for image segmentation

针对灰度不均匀图像难以正确分割和分割结果依赖于初始轮廓的问题,提出一种快速稳定的分割算法,首先通过自适应距离保持水平集演化(AdPlS)算法进行初始分割以获取较好的初始轮廓,然后采用局部二值拟合(lbf)模型进行快速分割。实验表明,改进后的模型有良好的分割效果,较好地解决了分割速度、精度及稳定性之间的矛盾。It is difficult to get the correct segmentation results for the intensity inhomogeneity images,and the segmentation results are very sensitive to the initial contours.Thus,a fast and stable approach was proposed to overcome these disadvantages.First,an Adaptive Distance Preserving Level Set(ADPLS) method was utilized to get a better initial contour.Second,the Local Binary Fitting(LBF) model was used for a further segmentation.The experimental results show that the improved model can achieve good performance and is better to solve the contradiction among the segmentation speed,accuracy and stability.南京军区重点项目(11Z023); 福建省自然科学基金资助项目(2008J0312
