集成遥感与GIS技术的土地利用动态变化监测方法研究

尽管国内外已发表了许多利用两个或两个以上时相遥感影像进行土地利用动态变化监测的研究成果,但鲜有基于单时相遥感影像与土地利用现状图进行土地利用动态变化监测的研究成果出现。本文将以土地利用现状GIS数据和高分辨率遥感影像为数据源,探讨利用GIS数据和相应分辨率的单时相遥感影像进行土地利用动态变化监测的有关技术方法和技术流程,并通过实验验证方法和技术流程的有效性和可行性。     

What Plato Knew About Enron

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created its image and presented information to support that image, and how the public eventually emerged from the cave to realize the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and moral responsibility of Enron’s executives.

An Empirical Analysis of Synthesizing the Effects of Festival Quality,Emotion, Festival Image and Festival Satisfaction on Festival Loyalty: A Case Study of Macau Food Festival

This study aims to examine the interrelationships among the festival quality dimensions, festival quality, emotion, festival image, festival satisfaction and festival loyalty. Analysis of data from 454 attendees in the 12^th Macau Food Festival indicates that the proposed model fits the data. The result of this study will assist festival management in developing and implementing market‐orientated service strategies to increase quality and image, and enhance the emotion and satisfaction of attendees in order to attain their loyalty toward food festivals.

成都旅游形象重新定位探讨——以多元分析的观点

近年来,成都在旅游形象定位上的摇摆不定,已成为困扰当地旅游业发展的一大制约因素。以多元分析的观点来分析以往定位形象的不足及成因,综合成都城市个性、游客本底感知形象、形象替代与叠加、形象演进态势等,将成都概括为"富丽天府都,百味休闲城"的总体形象定位。为实现投射形象与知觉形象相吻合,针对各目标区域市场,以实现构建系列化主题形象。     

从文化影响看译者对唐诗意象的英译——以庞德、韦利和许渊冲的译作为例

唐诗是世界文学大花园中绚丽夺目的奇葩,所以唐诗英译既是中西文化交流的需要,也是国内外翻译界的追求。而译诗即译意象,所以唐诗意象的英译直接影响原诗内涵的传达。通过学习与分析国内外翻译名家庞德、韦利、和许渊冲的译作来研究中西文化差异导致的思维差异在对文化意象转译中的表现,进而总结译者的翻译风格,能为今后的唐诗意象英译工作提供帮助,也能更好的在世界范围内弘扬中国文学与文化。     

SIFT算法的介绍和应用

SIFT算法是众多图像匹配算法中被广泛应用的一种,其具有良好的尺度、光照和空间旋转不变等特征。文章介绍了SIFT算法的4个主要步骤,并将该算法应用到多色二值压缩算法中,提高了压缩效率,缩小了压缩后的存储空间。     

一种改进的松弛迭代图像配准算法

本文展示了一种改进的松弛迭代图像配准算法,此算法首先使用归一化自相关运算求得图像的粗匹配对,接着使用改进的松弛迭代匹配算法进行精匹配。本文通过优化筛选第一轮迭代结果,使得后续迭代时间明显减少。实验证明此算法效率比原始算法有了很大的提高。     

射线底片的影像特征对压力容器制造单位质量管理体系运行的指导意义

压力容器产品的制造国家实施强制性的、法定的监督检验制度,在监督检验过程中通过对RT底片的审查,利用RT底片的影像特征来纵观产品制造所采用的焊接方法及整休焊接质量,可以判断产品焊接试板的数量是否满足法规、标准的要求,是否完全执行了焊接工艺,是否严格按返修的程序对缺陷进行返修等,从RT底片这一个点来纵观质量管理体系这个面,从而可以找出质量管理体系运行中的薄弱环节,使压力容器制造单位的质量管理体系能够保持正常、有效的运转,从源头上确保压力容器产品的制造质量。     

The relationship between store image and store brand equity: A conceptual framework and evidence from hypermarkets

Retailers are making considerable efforts to improve their brand management. The challenge they face, however, is how best to integrate coherently their stores, as brands, and their various distributor brands (store brands, private labels, etc.), in order to increase their brand equity and offer the market differential value that will stimulate customer loyalty. From this perspective, it is crucial for retailers to investigate the relationship between the store and their own brands. This study proposes two theoretical models showing the mechanism whereby store image helps increase the equity of a specific type of distributor brand (the store brand). The approach used in this analysis is based, on the one hand, on defining brand equity through its components, using the model in Aaker (1991), and on the other, on including (social and strategic) corporate dimensions in measuring store image. The empirical research made in the hypermarket sector in the Basque province of Gipuzkoa backs the majority of the proposed hypotheses. The results show that store image can be used by retailers to influence all components of store brand equity, essentially through its commercial and strategic dimension. This research is intended to address the clear lack of research on store brand equity.
