句法增强的UCCA语义分析方法

考虑到句法结构与语义结构之间的紧密联系, 尝试将句法信息融入UCCA语义分析模型中来增强语义分析的性能。基于目前性能最好的基于图的 UCCA语义分析模型, 提出并比较4种不同的融入依存句法信息的方法。采用SemEval-2019国际评测语义分析任务的英文数据集进行实验, 在本领域和跨领域两个数据集上的结果均表明, 句法增强的方法能够给显著地提高UCCA分析性能。引入BERT特征后, 句法信息仍然可以提供一定的帮助。     

在化学实验课程教学中引入模拟创业的探索和体会

Under the background of the times when the state promotes innovation and entrepreneurship, the department of chemistry of Fudan University has introduced the concepts of innovation and cost accounting into the laboratory course of analytical chemistry to cultivate students' awareness of entrepreneurship and environmental protection etc. At the same time, it can further enhance students' interest in the laboratory course.     

Sequent calculi for branching time temporal logics of knowledge and beliefwith awareness: Completeness and decidability

In this paper, we consider branching time temporal logic CT L with epistemic modalities for knowledge (belief) and with awareness operators. These logics involve the discrete-time linear temporal logic operators “next” and “until” with the branching temporal logic operator “on all paths”. In addition, the temporal logic of knowledge (belief) contains an indexed set of unary modal operators “agent i knows” (“agent i believes”). In a language of these logics, there are awareness operators. For these logics, we present sequent calculi with a restricted cut rule. Thus, we get proof systems where proof-search becomes decidable. The soundness and completeness for these calculi are proved. Published in Lietuvos Matematikos Rinkinys, Vol. 47, No. 3, pp. 328–340, July–September, 2007.     

Finite element modeling of syntactic foam

A decomposition model has been developed to predict the response of removable syntactic foam (RSF) exposed to fire-like heat fluxes. RSF consists of glass micro-balloons (GMB) in a cured epoxy polymer matrix. A chemistry model is presented based on the chemical structure of the epoxy polymer, mass transport of polymer fragments to the bulk gas, and vapor-liquid equilibrium. Thermophysical properties were estimated from measurements. A bubble nucleation, growth, and coalescence model was used to describe changes in properties with the extent of reaction. Decomposition of a strand of syntactic foam exposed to high temperatures was simulated.     

加强大学生环境意识教育的必要性及措施

随着我国高等教育的逐步普及,大学生的数量正在逐年上升,但是很多高等学校往往只注重对学生专业技能的培养,而忽视了对他们环境意识的教育,部分大学生已成为环境的破坏者。因此,提高大学生环境意识应该已经成为高校教育的重要组成部分。     

提高学生课堂参与意识,培养学生终身体育观念

随着社会的不断发展,人们的体育价值观念也随之改变,终身体育思想也逐步开始确立.但是,由于长期的课程负担和对学习成绩的要求以及社会压力,致使学生无暇进行体育锻炼,缺乏体育参与意识,身体素质不容乐观,更没有形成终身体育的意识.因此,高校体育教学中教师应该注重培养学生终身体育观念,激发学生成就动机,提高学生的体育参与意识,从而进一步提高体育教学的教学效果.本文从影响体育参与意识的因素入手,重点分析了如何培养成就动机和终身体育态度的方法.

沈阳居民光污染认知度的调查分析

以沈阳市居民对光污染的认知情况为实例，开展了问卷调查与分析，收回464份有效问卷.对有效问卷进行了统计分析.调查分析结果表明:有光污染意识的居民不到10%，从不知光污染概念的居民高达20%；虽然90%以上的居民认为夜间过亮的灯光严重影响睡眠，但当遇到光污染侵害时，大多数(639%)居民持忍受态度，并无意识采取法律手段来解决问题.可见，沈阳居民对光污染的认知度还很低.
