联机公共检索目录(OPAC)改进述评

对OPAC 研究中所提出的改进建议进行了评述, 归纳出三种方法: 增加主题检索途径, 改进书目记录, 如增补目次和书后索引再结合自动截断等; 增加检索手段, 改进检索性能, 如加权、反频率排列、检索树等; 重新设计屏幕, 改进人机界面, 如减少查找主题标目的扫描次数、首先考虑快速检索所需的选项、采用图形界面、模拟图书图像浏览等。     

多媒体课件中的视觉文化

多媒体课件的使用将会成为一种必然,它不仅用在传统的课堂上,也会在网上使用,它对教学的促进作用也是逐渐被大家所认识并被接受,在多媒体课件中大部分信息是视觉方面的,在多媒体课件中的视觉文化包含了许多方面,本文就多媒体课件交互界面的设计进行了分析。     

How are we now? Real-time mood-monitoring as valuation

In a digital society, we are frequently invited to communicate our present affective state via interfaces. These include smart-phone apps which allow users to track their mood in ‘real-time’, plus touchpads in organisations and public spaces which seek rapid feedback on whether an experience is positive or negative. In contrast to the use of surveys as tools of valuation, these technologies seek to capture experience in ‘real-time’, which can then be viewed and evaluated critically at a later time. Based on study of a number of mood-monitoring technologies, this paper highlights some of the ways in which they challenge conventional accounts of (e)valuation. In particular, rather than inviting individuals to represent their feelings towards the past numerically, they invite them to make uncritical expressions of positive or negative mood in the present. The central question of value is no longer how much is something valued, but whether or not it is valued. Quantitative and calculated analysis of positive and negative emotions occurs subsequently.     

多通道用户界面在举重训练数据管理系统中的应用研究

伴随着计算机信息技术的迅猛发展，计算机辅助训练的各种应用研究正受到越来越多的关注。作为其中的重要部分，训练数据实时管理与测评系统的研究更是备受关注。然而，考虑到训练数据采集的多样性和时空的不确定性，现有基于窗口的单一图形界面的训练数据管理与测评系统给使用者带来了极大不便，难以做到训练数据的实时管理与测评，严重制约了运动训练向科学化发展的步伐。在探讨不同应用环境中的多通道界面和交互方式的基础上，设计开发了多通道交互的举重训练数据管理与测评系统，以达到随时随地对训练数据的实时监管。     

艺术体操项目动作与音乐交互作用的探讨

艺术体操是一项手持轻器械在音乐伴奏下进行的体育项目,优秀的艺术体操运动员在展示精湛身体和器械动作技巧的同时,还会把音乐的意境传达给观众,使观众陶醉于意象之中。因此,动作是音乐的外在表现,音乐是动作的内在源泉,本文通过访谈、现场观察和视频分析,对艺术体操运动员动作与音乐的交互作用进行剖析。旨在通过梳理两者的关系,使之紧密结合、深度融合、相互促进,提高艺术体操项目的艺术表现力,对我国艺术体操项目实现追求极致美的目标提供有价值的理论依据。     

基于接口匹配的语义Web服务自动组合研究

传统的Web服务缺乏语义信息,如何自动地根据服务请求,进行服务的动态组合成为一个迫切需要解决的问题.语义网使得网络中所有的信息都是具有语义的,使计算机能够理解和处理.通过把Web服务抽象成为具有输入和输出接口的实体,提出了基于接口匹配的Web服务组合方法.该方法通过计算服务接口之间的匹配程度,找出其潜在的依赖关系,能够自动、动态地发现潜在的Web服务,从而实现Web服务自动组合.     

Setup and application of a structural seismic hybrid simulation system on local area network

To implement structural hybrid simulation independent of the control system of any testing equipment in civil engineering, an external command control approach is put forward. Several setup technologies and the corresponding API approaches are investigated to simultaneously combine numerical simulation with physical testing. Hybrid program technology is put forward and described in detail, using Visual C++ program to effectively and accurately control testing equipment and MATLAB program to implement numerical simulation with easy extension. The control program of testing equipment and numerical simulation program are integrated by calling MATLAB engine in Visual C++. A hybrid simulation about a full-scale six-story masonry structure is carried out. The testing results manifest that the external command control approach has the versatility because of simple hardware connection and control program independent on control software of testing equipment; powerful program function of Visual C++ and flexible program of MATLAB are integrated by hybrid program technology; hybrid simulation system provides a realistic and cost-effective testing platform that enables earthquake engineer researchers to accurately and efficiently capture the seismic performance of large or complex structures without having to carry out physical testing of the entire structure.     

关于建设现代汉语颜色词属性库的构想

中文信息处理已发展到“词处理”阶段。在这一阶段中,现代汉语词库建设是一项重要的工程,文中论及的现代汉语颜色词属性库可视为汉语词库建设中的分支工程。现代汉语颜色词的特殊性,使现代汉语颜色词属性库的建设面临了许多难题,而这些难题恰恰为颜色词属性库的拟构提供了路径,针对现代汉语颜色词的实际,文中以《现代汉语词典》中的颜色词为例,对现代汉语颜色词中的一部分静态成员进行了尝试性的属性标记,并对相关颜色词素的构词能力进行了降频统计。试图在信息工程的大背景下借此研究管窥汉语符号系统对客观世界的表记功能

考虑服务水平约束的零售商订货策略研究

顾客服务水平的高低是决定企业运营成败的关键.本文从运营/市场界面管理的视角,对考虑服务水平约束的零售商订货策略进行了研究,得到零售商的最优订货策略存在并且唯一.在确定性需求的情况下,零售商的最优订货量和最大利润均随服务水平的提高而增加.在随机性需求的情况下,当服务水平较低时,零售商的最优订货量和最大期望利润跟服务水平无关;当服务水平较高时,零售商的最优订货量是服务水平的增函数,零售商的最大期望利润是服务水平的减函数.最后,论文讨论了需求波动对零售商最优订货量的影响.
