西门子LOGO!在汽车试验场交通灯系统中的应用

阐述以西门子LOGO!为控制核心的交通灯控制系统的组成、硬件配置、控制流程及软件实现。长城汽车股份有限公司一个试验场位于长城汽车第i制造事业部总装车间北侧．建成于2007年,耗资720万元人民币,占地面积40000m：,分里、中、外一i层跑道．环型结构．长约2km。现其内部建有喷淋、K＆C试验台等试验室及试验场管理部门建筑物．每天约有几十名人员出入此试验场．出入频次高峰集中在上下班和中午午餐时间。     

基于消费者感知的服装品牌LOGO设计评估研究

基于消费者感知的基础上,结合语义分析法和投射心理学试验应用于服装品牌LOGO设计评估,通过试验方案设计、试验样本的调研与选择、语意形容词组的选择、试验界面及过程设计,进行消费者感知试验及数据分析,构建了服装品牌LOGO设计评估体系并进行了个案实证研究。服装企业可据此评估体系对目标消费群进行服装品牌LOGO设计评估,确定消费者对品牌LOGO设计的感知是否与品牌定位相符合,新创品牌可根据服装品牌LOGO设计的评估结果与品牌定位的拟合度来选择品牌LOGO的设计方案。     

复合针刺非织造布的结构与吸声性能研究

针刺非织造布是一种多孔结构材料,具有良好的吸声性能。其生产工艺过程简单,原料来源丰富,具有广泛的应用前景。随着人们对环境的重视,人们正积极寻求消除噪声的途径,吸声材料发挥着越来越大的作用。本文分析了针刺吸声材料的结构,并从厚度、面密度和组成纤维细度三个方面分析了其对吸声性能的影响。     

基于SWOT及IFE分析城市高识别度LOGO符号设计研究

目的 城市LOGO设计多被视为主观性较强的工程,研究通过SWOT及IFE分析,试图为城市LOGO设计及其他LOGO设计提供比较客观的思考进路或研究范式。方法 基于城市发展溯源法和城市文化SWOT及IFE分析,精心筛选与取舍城市代表元素,促进LOGO设计师的匠心独运和画龙点睛。结果 以SWOT及IFE分析嵌入城市LOGO的设计之中,较易获得赋有个性、特色鲜明、关涉长远、识别度高的城市LOGO。结论 城市LOGO必须赋有特色,设计不是主观臆造,更不容模仿或抄袭,而是基于SWOT及IFE分析的城市优势元素析出,以及基于系列原则的优中取萃,突显城市特色、历史人文、资源禀赋和战略走向的设计和传播过程。     

输液管道颤振失稳的时滞控制

采用时滞主动控制方法对输液管道的颤振失稳进行控制,以提高输液管道系统的临界流速.首先构造时滞控制策略并建立时滞控制的偏微分方程;然后利用伽辽金法离散时滞偏微分方程将其转化为时滞微分方程组,从理论上分析时滞微分方程的稳定性,并通过Matlab Biftool软件包对时滞控制系统的特征根分布情况进行模拟,与稳定性理论分析结果相当吻合;最后通过有限差分法对时滞偏微分方程进行数值模拟,与稳定性理论分析结果基本吻合.结果表明:通过时滞主动控制输液管道的颤振,控制策略简单,而且效果较好.     

逻辑控制模块在磨机喷射润滑装置中的开发应用

介绍了一种新型的逻辑控制模块系统,以实例的方式讨论了SIEMENS公司的LOGO！逻辑控制模块在工程中的应用,将LOGO！的原理及优越性在实际中展示。该方案克服了以前传统控制中的一些缺点,将使用者带入一个新的境界。     

纳米Pd/Al2O3催化剂的制备及应用

采用氢电弧等离子体法制备的纳米钯粉制备了纳米Pd/Al2O3催化剂,并在重整后加氢反应中研究了其催化活性和选择性。扫描电镜（SEM）和透射电镜（TEM）显示,纳米Pd/Al2O3催化剂的其表面排列有序、呈蜂窝状,其载体的内部没有钯存在,而浸渍法所得的壳型Pd/Al2O3催化剂载体内部有钯的存在。在重整后加氢反应中,纳米Pd/Al2O3催化剂显示出较高的催化活性和优异的选择性能。     

How do children do mathematics with LOGO?

Abstract  This paper considers some results of a study designed to investigate the kinds of mathematical activity undertaken by children (aged between 8 and 11) as they learned to program in LOGO. A model of learning modes is proposed, which attempts to describe the ways in which children used and acquired understanding of the programming/mathematical concepts involved. The remainder of the paper is concerned with discussing the validity and limitations of the model, and its implications for further research and curriculum development.     

The intelligence left in AI

In its forty years of existence, Artificial Intelligence has suffered both from the exaggerated claims of those who saw it as the definitive solution of an ancestral dream — that of constructing an intelligent machine-and from its detractors, who described it as the latest fad worthy of quacks. Yet AI is still alive, well and blossoming, and has left a legacy of tools and applications almost unequalled by any other field-probably because, as the heir of Renaissance thought, it represents a possible bridge between the humanities and the natural sciences, philosophy and neurophysiology, psychology and integrated circuits-including systems that today are taken for granted, such as the computer interface with mouse pointer and windows. This writing describes a few results of AI that have modified the scientific world, as well as the way a layman sees computers: thetechnology of programming languages, such asLISP-witness the unique excellence of academic departments that have contributed to them-thecomputing workstations-of which our modern PC is but a vulgarised descendant-theapplications to the educational field-e.g., the realisation of some ideas of genetic epistemology-and tointerdisciplinary philosophy-such as Hofstadter's associations between the arts and mathematics-and the use ofAI techniques in music and musicology. All this has led to a generalisation of AI towards Negrotti's overallTheory of the Artificial, which encompasses further specialisation such asartificial reality, artificial life, and applications ofneural networks among others.
