老年人电脑VDT使用现状及照明要求调研分析

退休年龄延迟、退休返聘现象常态化以及互联网的快速发展,促使电脑、手机等视频显示终端(VDT)在老年人生活、工作中的需求量及使用率递增,但VDT作业也容易诱发老年人视觉疲劳。本文采用问卷访谈的方式,对老年人群的电脑使用现状、照明环境现状及需求、视疲劳状况进行调查分析。结果显示:老年人电脑VDT作业时间较长,视疲劳发生率较高;老年人VDT作业时对照明有需求,但对照明现状满意度不高;老年人倾向较高的环境亮度和屏幕亮度,偏爱白色光,认为环境亮度、屏幕亮度、光色是影响VDT视疲劳程度的主要因素。基于老年人的视觉特征,提出老年人对VDT照明环境的要求:较高的环境亮度;较大亮度对比度;高质量的显色性,避免低色温;应尽量避免眩光。本研究结论可为下一步研究适宜于老年人VDT作业的照明参数奠定基础。

提高风电并网价值最优储能容量配置研究

随着风电并网容量在系统中比例不断地提高,其出力随机性使净负荷波动范围、机组运行成本等增加而产生了负面价值。为量化风电并网负面价值,本文建立了含风电机组优化调度模型,根据其仿真结果定量分析了风电在不同渗透率下常规机组运行方式与系统运行成本的关系,指出了风电并网产生负面价值的主要原因;依据储能电量平衡原则,建立含储能装置的优化调度模型,确定了兼顾提高风电并网负面价值与系统总运行成本的最优储能装置容量。结果表明:风电渗透率为3.41%时,并网价值为正面;当渗透率提高到5.36%时,并网价值转为负面,在此过程中,基荷、腰荷火电机组启停次数增加起主导作用;削峰率达到0.75时,系统的总运行成本达到最小,该削峰率对应的储能容量为降低风电并网负面价值的最优容量。

Helping computing students develop a personal ethical framework

The teaching of computer ethics has taken on a new focus and importance in Australia since the publication in 1997 of the Australian Computer Society's (ACS) body of knowledge for computing professionals. This includes the teaching of ethics in computing courses as mandatory for professional level accreditation of a tertiary degree. The ACS core body of knowledge states that computing students should be "encouraged to develop a personal ethical framework." In order to achieve this I believe it is essential to include the teaching of ethical theory in computer ethics courses as this knowledge gives students the means to analyze and resolve any ethical dilemma be it professional or personal. There are a number of different ways that computer ethics can be presented to students during a computing degree. Some of these are as a junior or senior stand alone course, as modules in other courses or integrated into the technical course. The course described is a senior stand-alone course

Senior design project: undergraduate thesis

Engineering design has become a critical element of the undergraduate engineering curriculum. To become accredited by the Accreditation Board for Engineering and Technology (ABET) requires that at least 24 credits of design content be included in the four-year undergraduate engineering curriculum. Senior design is the principal course in which students apply their knowledge in several disciplines to one project assignment and is a significant step towards meeting ABET requirements. Engineering experience acquired in the senior design course is a valuable aid to students as they learn how to apply theory to an actual design project. The senior design course develops project management and oral and written communication skills and enables students to learn scheduling, team coordination and cooperation, parts ordering, and cost/performance tradeoffs. Ten senior design projects that have won IEEE and SME student paper contests are presented herein as a guide in the difficult selection of suitable design topics. The unique nature of the senior design course requires certain departures from usual engineering course organization if students are to derive the maximum benefit. Senior design is nearly equivalent to an industrial internship and may be more valuable as the first step a student takes in making the transition to working engineer     

Engineering Design and Social Value

Because of the exponential growth of science and technology, the engineering student cannot hope to take more than a small sub-set of the many engineering courses available to him. The question often arises about the degree to which engineering students should find room in their cramped study schedule for work in the humanities, the social sciences, and other nonengineering topics. The engineer is faced with making value decisions in the realistic practice of his profession. In this paper, it is shown that making value decisions is inherent in the design process itself. It is also shown that the engineer's position in modem society is often at the right hand of major decision makers. Since many engineers are in a position where they cannot avoid sharing responsibility for decisions affecting social, political, and economic change, serious training in these areas appears desirable.     

Laboratory exercises for practical performance of algorithms anddata structures

This paper addresses the question of theoretical versus practical performance of algorithms and data structures. It describes an experiment the first author has been using in his data structures course to achieve the primary objective of comparing theoretical behavior of algorithms with their actual performance. It also presents enhancements in performance evaluation experiments and a general methodology that can be used to develop experiments in senior or first-year graduate courses in data structures, algorithm analysis, software engineering, and operating systems     

Dark Hero of the Information Age: In Search of Norbert Wiener The Father of Cybernetics (Conway, F. and Siegelman, J.; 2004) [Book Review]

This biography of Norbert Wiener spends less time looking at his enormous contributions to mathematics and far more time exploring his inner personal workings. The authors set out to establish that Wiener's importance and contributions to science and society have been forgotten, and that the man was, in essence, crazy. Although he exhibited erratic behavior and a chaotic temperament, Wiener was a fine scholar, a dedicated mathematician, an inspiring teacher, a tireless seeker of the truth, and in most respects a fine man. The author do provide insight into Wiener's (nonprofessional) life. They give a keen sense of what he was like as a child, as a teenager, as a young adult, and as a senior scholar. They also paint him as the father of information theory and the creator of cybernetics and talk about the feud with his colleagues in this area. Overall, the book portrays a side of Wiener that not everyone saw.     

Colloidal Nanoparticles in Biotechnology (Elaissari, A.; 2008) [Book reviews]

This book is written by an internationally respected scientist with extensive experience in colloids and biomolecules.

It is recommended for early-level graduate courses in biomaterials or as a reference text.
