社交网络技术在科研教学环境中的应用研究

随着互联网产业的发展、用户规模的扩张和用户行为的变化,以Web2.0为特征的相关需求应运而生。SNS,Social Networking Services,专指旨在帮助人们建立社会性网络的互联网应用服务。依赖其开放性,即时性,互动性,不受时间地点约束等特点获得青睐,很多社交网站如twitter,Facebook,人人网,微博在流量、用户数和市值都有引人瞩目的成绩。社交网络的特性适用于知识的共享,将SNS和E-learning结合产生的面向知识管理的社交网络KMOS系统既使学生在社交网络服务中获取到知识,又打破传统教学受时间、地点的束缚,开放共享知识,一对多的高效传播模式。设计和实现的面向知识管理的社交网络服务拥有的上述优点。使用列表和群组控制多媒体资源的传播范围。分层和插件式设计使系统灵活应对需求改变。使用社交网络技术提高教学质量。     

一种基于双椭圆模型的视频人数统计方法

一种基于双椭圆模型的视频人数统计方法针对环境和背景较复杂的情况,实现了较密集人群和部分遮档的人流数统计。首先提取运动目标的外形轮廓,将外形拟合成椭圆,再根据先验知识在轮廓椭圆内拟合头部椭圆。如果外形和头部都能成功拟合成椭圆,就能简单确定出一个人体。当人群密集时,先将目标进行分割后,再进行基于双椭圆模型的目标识别。本方法适合镜头的垂直模式、倾抖模式、近景模式、远景模式,能够在鉴别人体与非人体的基础上统计人数。分别对静态图像和视频序列进行了仿真,结果表明,该方法能够准确地进行人数统计。     

Towards understanding the underlying structure of motivational factors for software engineers to guide the definition of motivational programs

Aim

In this article, factors influencing the motivation of software engineers is studied with the goal of guiding the definition of motivational programs.

Method

Using a set of 20 motivational factors compiled in a systematic literature review and a general theory of motivation, a survey questionnaire was created to evaluate the influence of these factors on individual motivation. Then, the questionnaire was applied on a semi-random sample of 176 software engineers from 20 software companies located in Recife-PE, Brazil.

Results

The survey results show the actual level of motivation for each motivator in the target population. Using principal component analysis on the values of all motivators, a five factor structure was identified and used to propose a guideline for the creation of motivational programs for software engineers.

Conclusions

The five factor structure provides an intuitive categorization for the set of variables and can be used to explain other motivational models presented in the literature. This contributes to a better understanding of motivation in software engineering.     

试论“利他(它)利己”可持续发展观

陈昌曙教授曾经将布鲁兰特夫人的可持续发展观归纳为“利己不损人” ,我们将它拓展为“利他(它 )利己” ,并对“利他 (它 )利己”可持续发展观进行了一些诠释和初步探讨     

体现以人为本的空间组织思维方式——从环境心理学角度论人性化建筑环境

在人和环境组成的环境系统中,人是核心,因此环境设计理所当然应以人为本．把满足人的生理和心理需要放在第一位。因此。“以人为本”的设计理念是建筑师在建筑设计过程中应当追求的本源。     

What practitioners consider to be the skills and behaviours of an effective people project manager

It is recognized by academics and the community of practice that the management of people plays an important role in project management. Recent people skills research expresses the need to develop a better understanding of what good people management is. This paper proposes what project management practitioners consider to be skills and behaviours of an effective people project manager. A combination of literature review, face to face interviews and focus group meetings was applied to complete the research objective. Six specific skills and associated behaviours were identified as being most important. The results suggest that project managers would benefit from adopting these skills and behaviours to strengthen their managing people skills and behaviours to improve the successful delivery of projects. The findings also suggest that some skill sets and behaviours may be more appropriate for application in certain project environments such as IT or the construction industry.     

Real-time people localization and tracking through fixed stereo vision

Detecting, locating, and tracking people in a dynamic environment is important in many applications, ranging from security and environmental surveillance to assistance to people in domestic environments, to the analysis of human activities. To this end, several methods for tracking people have been developed in the field of Computer Vision using different settings, such as monocular cameras, stereo sensors, multiple cameras. In this article we describe a method for People Localization and Tracking (PLT) based on a calibrated fixed stereo vision sensor, its implementation and experimental results. The system analyzes three components of the stereo data (the left intensity image, the disparity image, and the 3-D world locations of measured points) to dynamically update a model of the background; extract foreground objects, such as people and rearranged furniture; track their positions in the world. The system is mostly suitable for indoor medium size environments. It can reliably detect and track people moving in an medium size area (a room or a corridor) in front of the sensor with high reliability and good precision.     

哈雄文和他的建筑人生路——纪念哈雄文先生诞辰110周年

哈雄文1927年在清华学校毕业后赴美国留学,1932年毕业于宾夕法尼亚大学美术学院建筑系和艺术系,1958年由同济大学来到哈尔滨工业大学,筹建哈尔滨建筑工程学院。他是我国第一代建筑与城市规划的留学生和前辈建筑师之一,是我国近现代建筑与城市规划领域的设计大师、学术大家、政府高级行政官员、职业团体领导人、教育家。本文谨从富国利民心、建筑教育情等方面来叙述哈雄文先生所走过的建筑与城市规划人生路,谨以此来纪念其诞辰110周年。     

基于自然的人性解读——兼论人类自然情结与人性化空间设计

"以人为本"是现代园林设计的基本原则,对"人性"的研究具有重要的理论意义。该文基于人与自然的关系,系统归纳、解读了各种人类自然情结,分析了其游戏化、生活化和艺术化的演绎和表达,揭示了其中的人性本质和人性的自然起源及其自然属性,提出自然情结的游戏化、生活化和艺术化演绎分别代表了人性中自然属性的"本我"表达、"自我"表现和"超我"再现。最后,总结了自然的人性具有自然性、永恒性、多样性和多层性,为"以人为本"的园林设计原则提供了新的理论基础。
