论司马迁与普鲁塔克人物传记中的历史比较     

王成军 《北京师范大学学报(社会科学版)》2006,(6):64-73

司马迁与普鲁塔克人物传记中的历史比较具有相同之处,即两者都紧紧围绕传记人物性格的同与异两方面展开,都具有比较发达的历史比较类型意识和明确而细致的比较观念;不同之处则在于,从比较史学的观点来看,普鲁塔克传记的重点是在比较认识的第一阶段———异中求同,侧重于表现传记人物性格的共性和道德理想性,因而其史学比较还局限于道德史学的范畴之中;司马迁则在异中求同的基础上,进一步在同中求异,因而列传中历史人物一方面能够同真实的历史联系起来,以展现历史的个性,突出地体现了传记的史学比较特色;另一方面也表明司马迁的比较史学思想突破了道德史学的桎梏,进入了探求历史规律———“成一家之言”的思想境界。造成这一差异的根本原因在于两者各自历史观念和世界观的不同。从现代传记史学观念来看,司马迁的比较史学观念更符合现代中西史学比较的发展趋向。  相似文献   

一种基于DHT的实数插值并行新算法     

李中年  张宁  董睿 《人天科学研究》2009,(7)

提出了实数插值并行算法:采用一种高效优化的1-D插值替代经典公式插值,实现2-D插值,使得运算简便迅速,其计算模式类似于"流水"运行,不需要数据记录和数据暂存设施;而且插值运算时间的复杂性同插值单元因子的复杂性互不相关;每个插值计算周期持续时间相当于执行一个相应的加法运算和乘法运算时间;这为实现高速计算、存储共享的并行处理硬件设施提供了设计依据。  相似文献   

Automatic extraction of bilingual word pairs using inductive chain learning in various languages     

Hiroshi Echizen-ya  Kenji Araki  Yoshio Momouchi 《Information processing & management》2006

In this paper, we propose a new learning method for extracting bilingual word pairs from parallel corpora in various languages. In cross-language information retrieval, the system must deal with various languages. Therefore, automatic extraction of bilingual word pairs from parallel corpora with various languages is important. However, previous works based on statistical methods are insufficient because of the sparse data problem. Our learning method automatically acquires rules, which are effective to solve the sparse data problem, only from parallel corpora without any prior preparation of a bilingual resource (e.g., a bilingual dictionary, a machine translation system). We call this learning method Inductive Chain Learning (ICL). Moreover, the system using ICL can extract bilingual word pairs even from bilingual sentence pairs for which the grammatical structures of the source language differ from the grammatical structures of the target language because the acquired rules have the information to cope with the different word orders of source language and target language in local parts of bilingual sentence pairs. Evaluation experiments demonstrated that the recalls of systems based on several statistical approaches were improved through the use of ICL.  相似文献   

Analyzing imbalance among homogeneous index servers in a web search system     

C.S. Badue  R. Baeza-Yates  B. Ribeiro-Neto  A. Ziviani  N. Ziviani 《Information processing & management》2007

The performance of parallel query processing in a cluster of index servers is crucial for modern web search systems. In such a scenario, the response time basically depends on the execution time of the slowest server to generate a partial ranked answer. Previous approaches investigate performance issues in this context using simulation, analytical modeling, experimentation, or a combination of them. Nevertheless, these approaches simply assume balanced execution times among homogeneous servers (by uniformly distributing the document collection among them, for instance)—a scenario that we did not observe in our experimentation. On the contrary, we found that even with a balanced distribution of the document collection among index servers, correlations between the frequency of a term in the query log and the size of its corresponding inverted list lead to imbalances in query execution times at these same servers, because these correlations affect disk caching behavior. Further, the relative sizes of the main memory at each server (with regard to disk space usage) and the number of servers participating in the parallel query processing also affect imbalance of local query execution times. These are relevant findings that have not been reported before and that, we understand, are of interest to the research community.  相似文献   

基于模式的并行程序设计方法的研究现状     

雷利桂 《科技广场》2006,230(1):108-110

并行程序设计是并行计算的难点之一,基于模式的并行程序设计方法为程序员提供了并行程序的框架,比使用并行库(PVM和MPI)具有更高的抽象程度和通用性。本文简单地介绍了目前国际上三种应用此方法所开发的模型或项目以及我们所研究的SRVRT模型,并做出了比较。  相似文献   

Building parallel corpora by automatic title alignment using length-based and text-based approaches     

Christopher C. Yang  Kar Wing Li 《Information processing & management》2004,40(6):27

Cross-lingual semantic interoperability has drawn significant attention in recent digital library and World Wide Web research as the information in languages other than English has grown exponentially. Cross-lingual information retrieval (CLIR) across different European languages, such as English, Spanish, and French, has been widely explored; however, CLIR across European languages and Oriental languages is still in the initial stage. To cross language boundary, corpus-based approach is promising to overcome the limitation of the knowledge-based and controlled vocabulary approaches but collecting parallel corpora between European language and Oriental language is not an easy task. Length-based and text-based approaches are two major approaches to align parallel documents. In this paper, we investigate several techniques using these approaches and compare their performances in aligning English and Chinese titles of parallel documents available on the Web.  相似文献

基于三维虚拟现实技术对周施雄双杠后上转体450°成倒立动作的分析     

周继和  王帅  刘艺  李溪 《成都体育学院学报》2015,(6):96-99

在世界上,中国运动员周施雄首次完成双杠后上转体450°成倒立动作。本文应用三维录像解析法对周施雄在比赛现场所做的后上转体450°成倒立动作采集运动学数据,利用沉浸式三维虚拟现实技术对获得的运动学数据进行重建,通过360°的旋转再现观察,以三维动画的形式进行运动学分析。研究发现周施雄在比赛中虽然完成了这一动作,但还有待完善。主要问题有上摆阶段伸髋较早、幅度稍大,导致在下一阶段的转体过程中单臂支撑的时候人体重心离支撑点的水平距离偏大,身体产生了倾斜,影响了之后的倒立动作,另外在转体阶段两腿并未完全并拢。  相似文献

What does the greek model of parallel support have to say about co-teaching?     

《Teaching and Teacher Education》2016

Parallel Support (PS) is a co-teaching program designed to deliver education services in inclusive settings in Greece. In this quantitative study, 236 special education PS teachers from six major educational regions participated in a survey. The findings indicate that PS is similar to the One Teach, One Assist approach, constituting a static model, which typically provides services to one or two students with disabilities. Deeper cultural characteristics of the Greek educational system may shape the PS's peculiarities. In our transcultural hypothesis, the PS model is a compromise between a highly demanding collaborative approach and a pre-existing low collaboration school culture.  相似文献
