北京市居住区屋面集雨资源的潜力分析     

季文华  蔡建明  和克俭  VAN VEENHUIZEN René 《资源科学》2010,32(2):282-289

随着中国快速城市化,传统的供水方式正面临严峻挑战,雨水利用这一古老的水资源利用技术,被实践证明是解决城市水问题的重要手段之一。与城市其他不透水面集雨利用相比较,屋面收集的雨水水质高,因此屋面集雨利用系统在世界上被广泛应用。本文建立了居住区屋面集雨利用潜力的计算方法,并据此计算出北京2002年～2007年居住区屋面依据实际年降水量和多年平均降水量可收集的水量分别为2.16亿m3和2.75亿m3,雨水利用对家庭生活用水的节水效率分别为7.2%和9.3%。通过分析影响北京雨水利用的因素,预测了2020年北京居住区屋面可收集水量与不同情景下的收集利用量。最后针对北京雨水利用存在的问题提出了相应的政策措施。  相似文献

Quality Assurance in an Academic Unit: A Case Study     

L. GELDERS  A. PROOST  C. VAN DER HEYDE 《European Journal of Engineering Education》1993,18(4):369-374

Total quality management (TQM) is a philosophy that is now accepted worldwide in the business environment. However, in higher education, quality management is not widespread. Quality efforts are mainly limited to specific tasks, such as course development, curriculum design, laboratory certification, etc. The Division of Industrial Management at K. U. Leuven decided in 1990 to develop and implement a total quality approach in its organization. This process recently resulted in a total quality system based upon the implementation of a quality handbook. This paper describes this unique experience of TQM in an academic unit.  相似文献

Training for Technology Entrepreneurs     

FABIAN MONDS  DICK VAN BARNEVELD 《European Journal of Engineering Education》1988,13(4):447-454

New technology-based business enterprises need qualified and highly motivated entrepreneurs with access to technical resources, facilities and expertise. This paper describes two training programmes for graduate technologists, which assist the transition from full-time education to successful entrepreneurial activity. The programmes are the European Technology Entrepreneurs Programme (ETEP) operating in Northern Ireland and in the Republic of Ireland, and Tijdelijke Onderemers Plaatsen (Temporal Entrepreneurial Placement, TOP) which operates in the Twente region of the Netherlands. Both programmes are sponsored by partnerships of universities and public authorities. The structures and features of ETEP and TOP, and the operating experiences since 1984, are described and discussed. It is concluded that technology entrepreneur development can be accelerated with the support of programmes such as ETEP and TOP. Arrangements for continued collaboration between the centres involved now includes participation in the EC SPRINT programme.  相似文献   

The Introduction of Portfolios in Higher Education: a comparative study in the UK and the Netherlands

This article describes a comparative study of the introduction of student portfolios in two departments of the Vrije Universiteit Amsterdam in the Netherlands and Nottingham Trent University in the UK. Portfolios are designed to facilitate effective management of lifelong learning, to provide a record of achievements and to encourage self-reflection by students.
The justifications for the portfolio initiative are different in the two countries. At the Vrije Universiteit, the initiative arose within the University but is being implemented by individual faculties. There is no standard model of implementation. At Nottingham Trent University, portfolios are being introduced as a response to a government directive, as part of a lifelong learning portfolio that each individual will carry forward into their working life. The University's response to this imperative is top-down and a University-wide model is being sought. The department model is one of several models that are being evaluated for this purpose.
This research project investigates whether these alternative starting points lead to differential responses from student users or not. Data are drawn from quantitative (questionnaires) and qualitative (interviews with managers, consultants and teachers) sources. Similarities and differences in students' responses to the portfolio exercise are identified and discussed in terms of factors such as the way the portfolios are introduced, the incentives offered to complete them, the role of the lecturer and peers in the monitoring of study progress, the quality of self-regulative skills, and students' learning expectations.  相似文献   

An Approach to Teaching Electrical Energy     

R. BELMANS  D. VAN DOMMELEN 《European Journal of Engineering Education》1996,21(1):65-73

The paper discusses the implementation of a new teaching programme for electrical power engineering graduates. The balance between the different parts of the curriculum (non-technical, technical non-electric, electric non-power and real electrical power) is proposed and explained given the specific context. The logical information flow throughout the education process and the links between the course topics are explained.  相似文献
