Abstract:
瓦片地图缓存技术是在网络GIS发展过程中产生的一种能够实现静态数据快速浏览的服务器缓存技术,同时近年来也被广泛用于三维地形显示中作为底层数据组织方式。在瓦片地图生产过程中,由于原始影像来源广泛,通常数据格式、投影方式、影像分辨率等均不一致,同时在切片过程中会存在根据地域范围或保密要求等因素需要对影像进行裁剪的等其他约束条件,在传统的切图流程中,会首先在遥感影像处理软件中对影像进行重投影、裁剪、拼接等操作,生成统一格式的中间影像,然后再输入到切图系统中,这种方式不仅效率低下,同时占用大量存储空间。本文在传统切图方法基础上,提出了在切图过程中逐瓦片使用一次多项式进行数值重投影实现的动态投影方法,以及基于扫描线填充算法的影像快速裁剪算法。通过实验对比分析,在多约束条件下使用本文算法能够实现一次性自动化切图,切图效率同无约束条件下切图效率相当,能够在基本不影响切图效率的同时完成瓦片金字塔构建,同时省去了影像预处理过程,极大的提升了处理自动化程度,降低了处理时间。
Tile map cache is a kind of service cache technique for quick accessing static map. It is developed during the progress of Web GIS. In recent years, it is widely used in 3D terrain display as the funda-mental data organization method. In the progress of tile map production, original image data are usually different in data format, projection, resolution and so on because of various data sources. Meanwhile, there are other restrictions such as image cropping by area of interest because of application localization or secrecy. So the traditional map tile generation begins with image re-projection, cropping and mosaic to produce united semi-finished image, and then puts it into map tiling software. This method is inefficient and takes lots of storage. Based on the method, this article suggests a dynamic projection using linear polynomial numerical projection and image quick cropping algorithm based on scan-line filling. The experimental results show that the method can realize automatic tile generation in one-time processing. The time it used is nearly the same as traditional methods which only deal with united semi-finished image. The algorithm can finish the map tiling without generating semi-finished image. As a result, it can improve the automation and reduce the processing time.

Abstract: 本研究结合DRM错误记忆范式(Deese-Roediger-McDermott paradigm)和自我参照效应的研究范式,以女大学生为被试,采用口头造句任务考察了关键诱词的情绪效价和不同参照加工条件对关联性错误记忆的影响。研究结果表明:1) 诱词的情绪效价影响了关联性错误记忆,表现为正性诱词比中性和负性诱词显示了更高的错误再认率;2) 相对于他人参照,自我参照加工具有诱发更强烈错误记忆的趋势。
The present study investigated how self-referential process influenced the associative false mem- ory for affective lures by combining the research paradigm of DRM with that of the self-reference effect. The following conclusions were drawn from the study: 1) The valence of the critical lures influenced the false memory. That is, the false recognition rate of the positive lures was higher than negative lures and neutral lures. 2) Compared to the other-referential processing condition, the recognition of critical lures has a ten- dency to increase under the self-referential processing condition.

Abstract: 本研究采用情绪启动范式,以首都师范大学在校生为被试,检验了简单形状的情绪效应。实验一发现快乐表情的情绪一致性效应,圆形启动刺激促进对快乐表情的判断,倒三角形启动刺激干扰表情判断。实验二发现形状的情绪一致性影响,倒三角形促进对消极词语的加工,干扰对积极词语的加工,圆形产生相反的作用。实验表明,圆形表征着积极意义,倒三角形表征消极意义,且这种情绪意义可以被自动激活,对认知操作产生不同的影响。
Selecting undergraduates of Capital Normal University as participants, the present work sought to examine the emotional meaning of simple geometric shapes with an affective priming paradigm. In Experiment 1, we found an effect of affective congruency on happy faces. Results showed that the happy faces were recognized faster after circle than inverted triangle primes. Experiment 2 revealed a significant effect of affective congruency. The inverted triangle facilitated the processing of negative words and interfered with the processing of positive words. The shape of circle had an opposite effect. The present findings support that inverted triangles represent an unpleasant or threatening meaning, whereas circles are perceived as pleasant stimuli. This meaning could be ac-tivated automatically and exert different influences on cognitive performance.

Abstract: 多重处理器系统的故障诊断是一个非常重要的研究课题。处理器系统的g好邻诊断度是在2012年被Peng等提出来的,它要求每个非故障顶点至少有g个非故障邻点。扩张3元n立方体是一个受欢迎的拓扑结构,它有许多好的性质。在本文中,我们证明了扩张3元n立方体在PMC模型和MM*模型下的1好邻诊断度都是8n-10(n≥4)
Diagnosability of a multiprocessor system is an important study topic. The g-good-neighbor diag-nosability of the system was proposed by Peng et al. in 2012, which restrained every fault-free node containing at least g fault-free neighbors. As a favorable topology structure, the augmented 3-ary n-cubes graph has many good properties. In this paper, we prove that the 1-good-neighbor diagnosability of augmented 3-ary n-cube is?8n-10?under the PMC model and MM* model for n≥4.

我国银行破产法律制度问题研究

法学家 , 2007,
Abstract: 由于银行在经济体系中发挥的重要作用及其业务的特殊性,一般的破产法并不完全适用于银行破产。银行破产往往可以划分为清算前和清算两个阶段。在清算前阶段,银行监管机构会通过各种措施救助银行。只有当救助无望时,破产银行才会进入破产清算。在这一阶段法律应明确规定监管机构采取行动的标准,以及可以采取的救助措施,限制其自由裁量权,避免监管姑息。而在清算阶段则应明确监管机构的权力。
双边投资协定中的伞形条款解释——兼论ICSID近期相关案例

法学家 , 2008,
Abstract: 近年来由于对投资保护范围的扩大,投资者与东道国所签订的合同往往亦属于双边投资协定保护的外国投资。若东道国违反合同义务,投资者一方面可以依据合同中的争端解决条款提起“合同之诉”;另一方面,在特定的情况下投资者可能就东道国违反合同义务的行为根据双边投资协定提起“条约之诉”。由于各方对有关双边投资协定中存在的“伞形条款”存在不同理解,使得“合同之诉”与“条约之诉”的竞合问题并未得到最终解决。本文通过对近期ICSID有关案例的分析,辅以对“伞形条款”的历史分析,提出只有当合同违反是因主权行为时,伞形条款方有将合同义务提升到条约义务的效果。

亚当·斯密的社会观:源于人性的自然秩序

社会学研究 , 2006,
Abstract: 本文试图从社会理论的角度出发来分析亚当·斯密的社会观,揭示他用人性来说明社会的自然秩序的努力。斯密认为,人并非自爱的孤立个体,社会秩序并非人理性设计的产物,而是源于人的社会性的本性,这就是人的同情和交换的本能。同情和交换把人与人联系在一起,并产生出社会的道德准则和经济秩序。人对同情和赞许的渴望使人服从道德准则,追求财富和地位,从而促进了社会的和谐与繁荣。
