Coordinating signs and eye gaze in the depiction of directions and spatial scenes by fluent and L2 signers of Norwegian Sign Language

The current study investigates the coordination of signs and eye gaze during depictions of directions and spatial scenes by fluent and second language (L2) signers of Norwegian Sign Language. First, findings show that fluent and L2 signers make different choices regarding the perspective they use to depict spatial scenes. Second, there is variation within and across groups in relation to how eye gaze is directed during these depictions. Findings suggest that eye gaze is used to establish a vantage point upon a depicted scene, but L2 learners may not always engage in this type of coordination. This study contributes to our understanding of how visual perspective is depicted in signed languages and has implications for signed language pedagogy.     

波音777飞机ACARS系统及马航MH370航班失联事件分析

马来西亚航空公司MH370客机失联事件一度引发媒体与公众的诸多猜测,猜测的焦点之一就是执飞的波音777飞机的飞机通信寻址与报告系统(Aircraft Communication Addressing and Reporting System,简称ACARS)功能是如何被关闭的。从专业角度出发,首先采用Sys ML建模的方式描述了波音777飞机ACARS系统的详细架构和人机接口,并据此深入分析了马航MH370航班失联事件中ACARS被关闭的情景。最后,提出了此次事件暴露出的现代民用飞机设计中存在的问题以及改进方法。     

法律适用中的语言学研究

法律适用的过程是将法律规则内含的旨意表达出来并使相关人接受、使相关事务得到合理解决的过程,最终使人与人之间的关系归于有序。而人与人之间的关系协调最终是需要通过语言使双方的意图被彼此接受,而法律只是其中的一部分。因此,从语言的角度讨论法律的适用,实质是研究如何使法律更好地得到实施的方法或途径之一。通过研究法律语言的现状从修辞学角度探究法律适用。

A Modeling Language Based on UML for Modeling Simulation Testing System of Avionic Software

With direct expression of individual application domain patterns and ideas,domain-specific modeling language(DSML) is more and more frequently used to build models instead of using a combination of one or more general constructs.Based on the profile mechanism of unified modeling language(UML) 2.2,a kind of DSML is presented to model simulation testing systems of avionic software(STSAS).To define the syntax,semantics and notions of the DSML,the domain model of the STSAS from which we generalize the domain co...     

商务英语模糊语语境顺应性研究

商务英语是国际商务活动的重要语言载体。模糊语在商务英语中有着不可替代的语用功能。以商务活动中的内部沟通语境和对外沟通语境为视角,对在这两种语境下商务英语模糊语的应用规律进行分析研究,应用顺应性理论对其进行解释,阐明在实际应用中应遵循这些规律,做到＂内外有别＂。对准确使用商务英语,提高商务沟通效率以及促进商务英语的教学等方面都有重要的意义。

基于Modelica的载人航天器环热控系统建模仿真

为了给载人航天器乘员营造一个良好的生活工作环境,需要将众多空气环境参数控制在指标范围内。文章结合载人航天器专业知识,基于Modelica统一建模语言建立了一种载人航天器环热控系统仿真分析模型;利用该模型仿真分析了温湿度控制风机取不同转速时,载人航天器空气环境参数随乘员代谢水平的变化趋势。结果表明:在其他参数不变的情况下,温湿度控制风机转速越大,空气温度越低,相对湿度越高;乘员代谢水平变化对空气环境参数有显著影响,通过调节系统运行参数可将各空气参数有效控制在指标范围内。舱体温度与氧分压、二氧化碳分压、舱体相对湿度有密切关系且相互影响,不可单独分析。     

Mining Spatial Associations with Limited Sensory Information

Abstract

Human navigation in an unknown environment requires an understanding of the spatial relationships of the terrain. For example, a soldier who is on a reconnaissance mission in a new city needs to “know” the spatial layout of the surroundings with high confidence. Oftentimes, this understanding must be acquired within a very short amount of time and with limited sensory inputs. The soldier would benefit from a digital avatar that draws inferences about the spatial layout of the city based on an initial set of observations and guides the soldier either in further exploring the environment or in making decisions based on these inferences. In this paper, we present and evaluate an inductive approach to learning spatial associations using sensory data that is available from the simulation environment of a computer game, Unreal Tournament. We study two kinds of spatial relationships between nodes on a level of a game map: nodes that are placed near each other to satisfy some spatial requirement and nodes that are placed near each other to satisfy the design preferences of a level architect. We show that we can infer both kinds of relationships using an association rule mining algorithm. Furthermore, we show how to use an ontology to distinguish between these relationships in order to discover different types of spatial arrangements on a specific map. We discuss how the inferred associations can be used to control an avatar that makes recommendations for navigating unexplored areas on a map. We conclude with some thoughts on the applicability of our methods to scenarios in the real world, beyond the simulation environment of a game, and on how the learned associations can be represented and queried by a simple question-answer type system.
