It is the first important step in video analysis and will directly affects the effectiveness of indexing Shot boundary detection is one of our major research interests and we will tackle the following existing problems the ambiguity between gradual change and camera motion, the discontinuity during gradual change, false detection caused by illumination variation and flashlight, automatic threshold selection Firstly, we discuss shot boundary detection in non-compressed domain In chapter 2, we compare some of the commonly used detection methods which are based on frame difference and point out that single feature will not generate good results As a conclusion, we use fuzzy logic to combine multiple features Presently, most frame difference based shot boundary detection algorithms rely on threshold and hence the selection of such thresholds will greatly affect the performance of boundary detection We propose a membership function to define frame difference and calculate the membership with self adaptation according to the statistic distribution of frame differences to satisfy different type of video clips Experiments show that the proposed fuzzy shot boundary detection algorithm can be used with different video types and has a high detection precision and recall In chapter 3, we discuss model-based shot boundary detection algorithms regarding chromatic and spatial editing effects such as fade-in, fade-out, dissolve and wipe Various parameters are proposed to better describe the characteristics of each editing type.

镜头边界的检测是把视频自动地分割为一个个镜头，作为基本的索引单元，因此它是视频分析重要的第一步，直接影响到视频检索的成败。镜头边界的检测是本文研究的重点之一。目前镜头边界检测算法主要存在以下问题：渐变与镜头运动难以区别；渐变过程中的不连续与停顿、光照条件的变化及闪光灯等特殊情况会引起误检测；自动选择阈值比较困难等。本文首先针对非压缩域视频进行了镜头边界检测的研究。在第二章中我们采用了比较流行的基于帧间差的方法。在比较各种帧间差计算方法的基础上，指出使用单一的特征难以取得很好的检测效果，提出用模糊逻辑综合使用各种特征。目前大多数基于帧间差的镜头边界检测算法都采用阈值法进行镜头转换的判别。阈值选择的误差对检测性能有较大的影响，本文提出用隶属度函数定义帧间差较大、中等较大和较小等概念，并根据帧间差的统计分布自适应地确定隶属度，以适应不同类型的视频片断。实验结果表明这种基于糊逻辑的镜头边界检测算法可以适应不同的视频，并具有较高的检测精度和检出率。在第三章中采用基于模型的方法进行镜头渐变的检测，研究了淡入／淡出、慢转换和扫换的模型。

学研究的范式——比较静态分析，是一种技术，通过这一技术，理论可以被考察研究，以确定理论的可驳斥假说，它是对进行的一种符合的仿真。具体讲，比较静态分析是通过逻辑运算，模拟理论的可驳斥命题即检验条件是什么，从而为理论的验证提供方法。用经济学的研究范式对陕西省"一线两带"的比较静态分析显示，此战略成立的必要条件之一是：随着战略的实施即政府对极化地区的投入，其产出增加应该比其它地区产出增加大，否则这一战略就不成立。也就是说，如果陕北或陕南经济发展更快，集中投资于西安等中心城市，并不是更好的战略。

The result shows that the cruciform specimen with square thinning center region is the superior device for the investigation of forming limit stress diagram to obtain the more homogeneous stress distribution in the center region, to realize the large deformation and the fracture appears in the center region more easily, and to control the stress concentration preferably.

It is characterized by well biologicalutilization rate and good taste; therefore, it is a hot topic for trophology and foodsproduce presently.

其生物利用率高、味道好且较好的利用了食物之间的互补作用，是目前营养学和食品生产领域研究的热点。

And many of these patients, who wouldn't normally get better, showed significant improvement, said Dr Christopher Bever, chief of neurology at the Veterans Administration Medical Centre in Baltimore, where one of the studies was conducted.

像许多一般情况都被认为不可能好起来的患者，都有了显著地进步。巴尔的摩的美国退役军人治疗中心神经学主管Christopher Beve博士介绍道。这所研究中心的研究有些已经开始施行了。

Contrast to the image retrieval ,the research in the audio field lagged.This paper summaries the situation of audio retrieval ,combining with material of the MPEG standard and content based retrieval .And propose the protype of a Query by humming sytem based on the ICA,which can solve the cocktail problem very good.

Study 1 summed up how different types of passengers influenced driving behavior via Driving Log. Study 2 was about a certain type of passengers, finding that "leader" could reduce drivers' propensity for angry driving behavior while "friend" increase it. Study 3 reversed the priming artifice, finding "leader" and "friend" made a different effort on drivers when compared to study 2. This three both suggested impression management strategy in driving.

研究三采用直接描述目标对象人格及行为特征的反向启动方式，&领导&和&好朋友&的作用又正好与研究二相反，即研究三中&领导&作为乘客反而增加司机的愤怒驾驶倾向，再次验证印象管理策略的作用；基于情境特点，此时分别考察自我监控能力和自我监控倾向的调节作用，只有倾向分量表的作用显著，即自我监控倾向越高，不同情境对司机的愤怒驾驶倾向影响越大。

In the first part of this thesis, it defines the concept of environmental evaluation, reviews the creation and development of environmental evaluation and the research present situation in China. It also accounts for that the environmental evaluation triers should study not only the research conclusion as the guide and basis of design and decision making, but also the evaluation pattern and method used in research.
