Development of a plastic injection molding training system using Petri nets and virtual reality     

马斌  郭志英  周华民 《浙江大学学报(A卷英文版)》2006,7(3):302-308

INTRODUCTIONAt present, plastic as a substitute for metals in products is the most important mainstay in industrial raw materials. Furthermore, plastic injection molding is one of the most common and versatile methods for mass production of complex plastic parts with excel-lent dimensional tolerance. Since the technology of injection molding has been widely applied in manu-facturing, training on injection molding is of great importance. The traditional approach is to consult some technica…  相似文献   

Effects of light and temperature conditions on flowering in Mat Rush     

沈伟其  张国平  奚利峰  桂文光 《浙江大学学报(A卷英文版)》2002,3(5):611-616

The effects of photoperiod and light intensity on flowering in Mat Rush cv. Gangshan 3 were studied. The results showed that treatments with longer day length stimulated flowering significantly and increased stem flowering percentage (SFP). Plants treated with low light intensity at early stage had substantially reduced florets per cyme, SFP, tillers per plant and stem length. At middle and late stage, low light intensity significantly reduced SFP. The principal climatic factors affecting SFP were as follows: mean temperatures (MT) of the third ten-day period (TDP) in December and of the second TDP in February, actual sunlight hours (SH) of the third TDP in February and precipitation of the third TDP in March. A nonlinear simulation model for SFP was established with experimental results and corresponding climatic data (see Eq. (2)). Simulation by the above equation yielded values the same as those observed from 1992 to 2000, indicating its accuracy in describing the relationship between flowering and light and temperature conditions. The interaction between vernalization and SH is also discussed in this paper. Project (No. 981105) supported by the Ningbo City Science Foundation, China  相似文献

Virtual university–a vehicle for development,cooperation and internationalisation in teaching and learning     

M. Pursula  M. Warsta  I. Laaksonen 《European Journal of Engineering Education》2005,30(4):439-446

The paper discusses the approaches of virtual university strategies and developments in Europe. The discussion is partly based on the work done in the Activity 5 in the EU Thematic Network E4 and partly to the experiences gained through the activities of EUNITE virtual university network of six European universities. Based on our experience we see, that e-learning and virtual university approach can be used for renewal of teaching and learning, both on and off campus. Just three years ago, universities seemed mainly to aim only to develop on campus teaching and learning through ICT. Lately, the use of e-learning as a tool for international cooperation and for virtual mobility (Virtual Erasmus) has started to develop through the activities of the European Union e-learning programmes and through the activities of some European university networks, like EUNITE. To promote virtual universities and e-learning, commitment and actions at all levels from EU to individual institutions are needed.  相似文献
