Space- and time-efficient approach for virtual machine provisioning

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.     

试谈高职学生职业生涯规划的尴尬与整饬

由于中国社会正处于转型期,社会职业的多变性与过渡性,经常会使高职学生职业规划研究陷入＂落伍＂的尴尬,又因实践与规划无法奏效而使职业规划指导或研究沦为空洞而抽象的说教。高职学生的职业规划的科学机理,应该定位于人文素质常项、专业技能常项的把握。当代职业多变或迁移过快,派生出了新职业对原有职业规划元素的适应、衔接和修正等一系列动态思维观照。     

翠湖休闲区休闲空间格局研究

翠湖区域作为昆明市中心的休闲区,其休闲空间对于昆明市民的休闲体验起着举足轻重的作用。在实地调查的基础上,运用景观生态学的斑块-廊道-基质的景观空间格局基本理论,对翠湖休闲区休闲空间格局进行分析研究,得出翠湖休闲区的景观格局为一＂核＂、两个廊道和九个斑块,并提出更新发展休闲空间,打造翠湖休闲文化圈的建议：保护翠湖自然生态,合理布局翠湖休闲空间;提升翠湖品位,更新发展翠湖休闲空间;突显翠湖文化元素,完美打造翠湖休闲文化圈。     

论文学的空间存在方式

文学空间首先表现为文学作品自身的物理存在空间。文学的存在也要占据一定的物质空间,这个层面是文学作品的外围的物理存在空间。语言的空间存在方式为文学赢得了它所独有的空间性。语言本身具有空间性,并且语言和表现手法是形成空间形式的主要工具。语言创造出的空间形式又是构成文学作品结构、情节、形象的空间形式的基础,文学自身的空间性还表现在修辞格上。

论自由基反应及其影响因素

上世纪初发现自由基反应,其特点有三引发、传递和终止;分为单分子和双分子反应.共振杂化体越多的自由基越稳定,对自由基稳定有利的空间构型其反应易进行,溶剂化作用、氢键的形成、过渡态活化能等对自由基反应都有影响.     

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.
