Virtual Serendipity: Preserving Embodied Browsing Activity in the 21st Century Research Library

As academic library collections are moved off site to make room for learning commons-type collaboration spaces, exploratory research processes (e.g. stacks browsing activities) are threatened. Given the range of benefits associated with chance information encounters in the physical book stacks, the disappearance of accessible collections is problematic. Fortunately, by focusing on embodied aspects of the physical browsing experience we can leverage emerging technologies to preserve instances of serendipitous information retrieval. Virtual reality, in this case, provides a browsing platform that allows for the type of search activity typically associated with research in the physical books stacks and preserves the benefits thereof.

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

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…

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

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.

虚拟仪器及其在实验教学中的应用

实验教学在高等工科教育中起着相当重要的作用,但是长期以来实验设备和实验教学方法的落后在很大程度上制约了实验教学质量的提高。将虚拟仪器技术引入高校实验教学中,为高校改善实验条件提供一种新的途径。本文采用LabVIEW语言开发了一虚拟仪器——虚拟示波器,来说明其在实验教学中的应用。     

指尖流转的文学新宠--手机文学

手机文学亦称“短信文学”或“拇指文学”,是创作者为手机量身定做、给手机用户提供可阅读文本的文学样式。受手机平台的限制,手机文学作品篇幅短小。手机文学具有语言精炼含蓄、内蕴深厚、哲理性强的特点。它的出现,大大拓宽了文学的表现对象,也给更多的文学青年开辟出一块新的发表园地。
