摘要：gStore is an open-source native Resource Description Framework （RDF） triple store that answers SPARQL queries by subgraph matching over RDF graphs. However, there are some deficiencies in the original system design, such as answering simple queries （including one-triple pattern queries）. To improve the efficiency of the system, we reconsider the system design in this paper. Specifically, we propose a new query plan generation module that generates different query plans according to the structures of query graphs. Furthermore, we re-design our vertex encoding strategy to achieve more pruning power and a new multi-join algorithm to speed up the subgraph matching process. Extensive experiments on synthetic and real RDF datasets show that our method outperforms the state-of-the-art algorithms significantly.

摘要：The one-ladle technology requires an efficient ironmaking and steelmaking interface. The scheduling of the hot metal ladle in the steel plant determines the overall operational efficiency of the interface. Considering the strong uncertainties of real-world production environments, this work studies the dynamic scheduling problem of hot metal ladles and develops a data-driven three-layer approach to solve this problem. A dynamic scheduling optimization model of the hot metal ladle operation with a minimum average turnover time as the optimization objective is also constructed. Furthermore, the intelligent perception of industrial scenes and autonomous identification of disturbances, adaptive configuration of dynamic scheduling strategies, and real-time adjustment of schedules can be realized. The upper layer generates a demand-oriented prescheduling scheme for hot metal ladles. The middle layer adaptively adjusts this scheme to obtain an executable schedule according to the actual supply–demand relationship. In the lower layer, three types of dynamic scheduling strategies are designed according to the characteristics of the dynamic disturbance in the model:real-time flexible fine-tuning, local machine adjustment, and global rescheduling. Case test using 24 h production data on a certain day during the system operation of a steel plant shows that the method and system can effectively reduce the fluctuation and operation time of the hot metal ladle and improve the stability of the ironmaking and steelmaking interface production rhythm. The data-driven dynamic scheduling strategy is feasible and effective, and the proposed method can improve the operation efficiency of hot metal ladles.

摘要：《钦契》是雪莱的一部取材于意大利真实历史事件的诗体悲剧,它在雪莱文学生涯中占有重要地位。遗憾的是国内很少有人关注它的价值,而国外这些年的研究多从戏剧艺术与人物、互文性、社会历史、宗教、伦理学、心理学、女性主义角度进行。本文另辟蹊径,采取文类研究方法,从文类政治角度对《钦契》进行研究,力图证明它是一部哥特式文学作品,进而说明作者充分利用这种文类的潜在的功能表达政治主题,实现对传统哥特文学的超越。

摘要：柯勒律治对英国浪漫主义诗歌创作和浪漫文学批评理论的贡献是有目共睹的。然而,学术界却在其文艺理论与谢林思想之间的关系上引发了一场是“抄袭”还是“借鉴”的学术“公案”。通过两人学术思想的比较,我们发现,在艺术创作与模仿自然的关系和艺术的本质两个层面上,柯勒律治受到谢林的影响是不言而喻的,但两人的观点和结论均自成体系,且柯勒律治最终走向了文艺理论方向,谢林则向哲学研究发展。此外,美国思想家爱默生的自然论也曾借鉴过柯勒律治的相关思想。根据词典对“抄袭”的界定、“抄袭”的时代内涵以及相关文学案例,结论是:两者属于借鉴关系,而非抄袭。该文以这场学术公案作为引子,在探讨这件公案的基础上,侧重研究了柯勒律治的浪漫主义文艺理论。

摘要：狄更斯不仅是伟大的现实主义小说家,同时也是一个具有强烈浪漫主义创作倾向的小说家。他从法国思想家卢梭和英国19世纪初期的浪漫主义作家那里汲取思想,创作了一系列具有浪漫主义特色的小说。他的代表作《远大前程》比较典型地反映了浪漫主义“回归自然”、关注儿童的创作思想。研究狄更斯这部小说中的一些具有明显浪漫主义特征的写作手法,会使我们纠正过去的一些偏见,进而增进我们对狄更斯创作思想的了解,拓宽对其小说艺术成就的研究。

摘要：匿名创作是文学史上的常见现象,其背后往往隐藏着意识形态、文化权力、个人心理等多重因素,对于作家匿名动机的考察对全面评价作家的艺术成就有着重要的意义。司各特匿名创作小说达13年之久,其作品中流露出了一种"匿而不隐"的矛盾意识。这是哈罗德·布鲁姆所言的"影响的焦虑"之结果,体现了司各特对当时过度张扬的"浪漫主义主体性"所带来的文学创作趋向以及"文学传记批评"这一批评范式的一种无声的反拨与抗拒,同时也体现了他作为苏格兰作家的民族身份焦虑意识。

摘要：伦理道德是理顺人际关系和维持社会秩序的要素之一,也是文学价值的重要组成部分并已形成其书写传统。受浪漫主义和现实主义文学的双重影响,英国维多利亚时期惊悚小说构成了对这两种思潮伦理道德书写传统的继承与扬弃的。该类型小说在伦理道德层面既有浪漫主义文学的“理想”成分,又有现实主义文学的批判精神,为人们了解英国维多利亚时期中产阶级的“善”“恶”伦理道德观打开了一扇窗口;其“惊悚”和“悬疑”的小说叙事策略构成的作品文学性也已超越了同时期的现实主义小说。鉴于其高超的文学艺术性和伦理道德的教化作用,该类型小说的伦理道德研究在当今和谐社会的建构中仍具有以文史为鉴的文学镜像作用。
