摘要：Java技术在企业信息系统整合、数据库应用、分布式计算、网络应用程序开发等都得到成功应用。文章研究J2EE平台上分布式环境下Internet网络应用程序设计方法,提出一个可以作为设计J2EE应用程序参考的设计样式-J2EE web application pattern,期望可快速地在J2EE平台上设计出架构合理、效能优异的应用软件。

摘要：作为美术设计人员,仅有对软件的熟练操作是远远不够的,如何能像使用麦克笔一样使用电脑这个先进的工具,让电脑充分反映人的思想与创意,而不是由人去表现电脑的特征,则是一个循序渐进的艰难过程。《童年的旋律》便是期望通过图形绘制及影像合成,赋予电脑画以一种主动的、人的感情。长大的人对童年往事都会有一种割舍不去的怀恋。

摘要：Based on the graphic theory and improved genetic algorithm,an improved genetic algorithm to search the minimum spanning trees is given . The algorithm uses binary code to represent the problem of minimum spanning trees. It designs the corresponding fitness function,operator and few controlling strategies to improve its speed and evolutionary *** one solution can be gotten with running traditional al-gorithem atone *** new algorithm can get a set of the solutions with higher probability in a shorter *** experiment shows that it has a better performance than traditional methods.

摘要：Design patterns are object oriented software design practices for solving common design problems and they affect software quality. In this study, we investigate the relationship of design patterns and software defects in a number of open source software projects. Design pattern instances are extracted from the source code repository of these open source software projects. Software defect metrics are extracted from the bug tracking systems of these projects. Using correlation and regression analysis on extracted data, we examine the relationship between design patterns and software defects. Our findings indicate that there is little correlation between the total number of design pattern instances and the number of defects. However, our regression analysis reveals that individual design pattern instances as a group have strong influences on the number of defects. Furthermore, we find that the number of design pattern instances is positively correlated to defect priority. Individual design pattern instances may have positive or negative impacts on defect priority.

摘要：在VS2013编程环境下,结合OpenCV设计了人脸活体特征检测实验平台。该平台由图像读取、人脸及五官检测、图像分块提取特征和机器学习部分组成。通过分析人脸真实图像与欺骗照片之间的纹理特征差异,实现对人脸真实性的判别。实验平台用于训练分类器的特征是Uniform pattern LBP特征向量,将该特征应用于活体检测是本实验的创新之处。在该实验平台上对Replay-Attack数据库和实际创建的数据库进行实验,实验结果可以看出平台的准确率及运算速度等方面具有优良的性能。

摘要：This paper reports on a series of Consciousness-Raising （C-R） activities focusing on prefabricated verbs chunks and verb patterns. An 18-week experiment was carried out incorporating the C-R activities into a Comprehensive English Course. A writing task and semi-structured interviews were administered after the experiment. Results indicated that （1） the frequency and accuracy of verb patterns used by Experimental Group （EG） were higher than those in the Control Group （CG）; （2） C-R activities promoted the use of the students’ reference material and their ability to notice gaps in meaning, enhanced their interest and confidence in learning English, and guided their personal learning of vocabulary; （3） the EG generally liked the activities.

摘要：Changes and reconfiguration of information systems(ISs)are two kernel concepts of rapidil reconfigurable in-formation system(RRIS).It is the abilitise to evolve with changes that make RRIS superior to the traditional *** architecture of RRIS is put *** then a component-based framework of RRIS is discussed including its building and designing in detail.

摘要：通过调查合肥市3个居住区组团绿地空间中居民的活动和期望,分析居民活动与绿地空间的密切关系,探索提出与居民活动相适应的人性化绿地模式。结果表明:人们有很强烈的休闲期望,其中以休息、活动身体和呼吸新鲜空气为最主要。绿地空间的活动也较为多样,以休息与散步为主,且居民活动与空间的性质、功能和设施有关。功能越多样,活动越丰富,满意度越高。同时,结合具体调查结果对绿地空间现状及存在的问题做出分析,在此基础上提出3个相应的绿地空间设计模式。

摘要：本文研究了TFT-LCD显示器制造工艺过程中边角发黄不良产生机理及其改善措施。通过对显微镜分析、PS高度、Cell Gap确认以及不良机理分析,得出在ODF工艺过程中液晶与未固化的封框胶接触时,边角位置处液晶快速扩散穿刺封框胶,同时由于区域性液晶填充过多造成发黄不良。本文从工艺上对LC pattern及Dummy区域封框胶涂布工艺改善,从设计上对Dummy区域填充R/G/B胶进行改善,二者对边角发黄均具有显著的改善效果,边角发黄位置处的穿刺程度从改善前的58.6%降低到5.3%,从而有效的提高了该产品的良率。
