Infants' sensitivity to optical flow for controlling posture.

Infants' sensitivity to optical flow for controlling sitting and standing was tested using a "moving room" in which all of the walls moved together, or only the side walls or front wall moved. Two questions motivated this research. (a) is the optical flow necessary for inducing postural compensations spatially distributed in the optic array? (b) Do visually induced compensations follow a developmental progression, or alternatively, emerge all at once? Experiment 1 was designed to test postural compensations by 14-month-old infants capable of standing in the moving room. Experiment 2 was designed to test postural compensations by 5- to 9-month-old infants who were passively supported while sitting in the moving room. The results revealed that partial flow is generally sufficient for inducing postural compensations, but that the amplitude and consistency of the response depend on the location of the flow in the optic array. In addition, there was evidence suggesting that compensatory responses become increasingly systematic during the second half of the first year.

Impacts of new technologies on media usage and social behaviour in domestic environments

Technological infrastructure at home is changing continuously and is becoming increasingly interconnected. Media devices, including the TV set, provide access to the Internet and offer manifold opportunities to consume media on demand. Additionally, personal devices, such as smartphones, also enable flexible consumption and sharing of media. Questions about how these technologies change the user's media usage and how these changes affect the social structure of a household, however, remain largely unanswered. In order to gain insight into the adoption of new technologies into daily routines, we explored these changes in respect of people's media usage in a qualitative long-term Living Lab study. We will present findings regarding personal routines, flexible integration of new devices into existing practices, influences on households as social systems and related issues in device access and collective use. We will highlight potentials and conflicts regarding device shifts and roles; restrictions in device access; social influences in the living room; and individual changes in media consumption.     

虚拟服装展示系统的比较研究

虚拟服装展示是借助立体全息技术、互联网或数字互动大屏幕来展示人体或数字角色“穿上”虚拟服装后的动态视觉效果。随着数字媒体艺术、交互技术和立体显示技术的发展,虚拟服装展示系统被广泛用于立体时装设计、服装表演、娱乐秀、商场试衣以及电视广告等领域。本文分析比较了近年来国内外虚拟服装展示领域的技术发展,并归纳总结出当前虚拟服装展示的5种人机交互模式。作者认为：随着全息技术、体感交互、立体视觉和增强现实等智能环境技术的发展,以“私人订制”为代表的个性化、时尚化和智能化的虚拟试衣体验将成为未来人们服装购买体验中不可或缺的重要环节之一。     

高校计算机机房管理模式的探讨

高校的计算机机房为学生提供日常授课、特殊考试、自主上机等服务,是高校开展信息教育的重要场所.机房的建设与管理工作水平直接体现了高校的信息化水平,也直接影响了计算机相关教学的教学质量.本文对传统的机房管理模式进行了分析,探讨了其优点与不足,并且提出了一种新型的机房专职管理教师与学生协同的管理模式,具有一定的参考价值.     

铝蜂窝负载锰基催化剂的制备及其在室温下去除低含量甲醛的性能

采用水热共沉淀法和原位氧化还原法制备MnO_x/MgAl类水滑石(Mg₃Al₁-LDHs)催化剂,以水玻璃作为黏结剂将其负载到铝蜂窝上,用于室温下去除甲醛。通过X射线衍射(XRD)、热重分析(TG)、X射线光电子能谱(XPS)、N₂吸附-脱附、傅里叶变换红外光谱(FT-IR)等手段进行表征。表征结果表明：MnO_x/Mg₃Al₁-LDHs具有典型类水滑石结构,大量结合水和羟基; MnO_x为δ-MnO₂和Mn₃O₄的混合物,具有高比例Mn⁴⁺/Mn³⁺和丰富的吸附氧。实验结果表明：室温(25 ℃,相对湿度60%)下反应4 h后,MnO_x/Mg₃Al₁-LDHs催化剂可将甲醛质量浓度由1.30 mg/m³降至0.10 mg/m³以下,且经过8次和连续15 d实际测试,表明催化剂具有良好的稳定性和甲醛去除效果。MnO_x/Mg₃Al₁-LDHs催化剂最佳负载量(质量分数)为5%,风扇最佳功率为10 W,空气中湿度对甲醛去除效果影响较小,该催化剂具有较强水分抵抗能力,反应温度提升会较大程度提高甲醛去除效果。     

Which symbol grounding problem should we try to solve?

Floridi and Taddeo propose a condition of ‘zero semantic commitment’ for solutions to the grounding problem, and a solution to it. I argue briefly that their condition cannot be fulfilled, not even by their own solution. After a look at Luc Steel's very different competing suggestion, I suggest that we need to re-think what the problem is and what role the ‘goals’ in a system play in formulating the problem. On the basis of a proper (syntactic) understanding of computing, I come to the conclusion that the only sensible grounding problem is how we can explain and re-produce the behavioural ability and function of meaning in artificial computational agents.
