Sailing on the Silicon Sea – The Design of a Virtual Maritime Museum

Following the development of a virtual museum this paper theorises the implications this has had for the Western Australian Maritime Museum (http://www.mm.wa.gov.au/). It is an opportunity to explore the relationship between both theory and praxis. The context for the analysis is the Diving into Shipwrecks internet project (http://www.mm.wa.gov.au/Museum/excavate/intro/intro_frame.html) developed as a constellation of shipwreck excavations. The success of the project is highlighted through an assessment of statistical data and more qualitative forms of feedback. Having established one model in a virtual museum this paper then reflects upon other forms of the web museums that are appearing on the internet. The discussion has implications for cultural organisations that seek to create on-line environments.

自然博物馆科研基地建设的思考 ——以重庆自然博物馆为例

自然类博物馆在全国定级博物馆中占比仅为2.2%,其中拥有科研基地的博物馆就更少。对已有自然博物馆科研基地调研表明,尚未做到相对独立的科研实体,必须紧紧依靠博物馆业务部门。因此,自然博物馆科研基地建设尚无成功案例可循,需要探索出适宜的建设发展道路。本文通过对重庆自然博物馆科研基地建设过程中遇到的问题进行深入思考,提出相应的对策,尝试为此类科研基地建设提供相应策略。

云计算技术驱动下构建数字图书馆虚拟化环境的探讨

考虑到云计算技术与虚拟数字图书馆的目标具有共同点,本文以云计算技术作为构建虚拟数字图书馆的基础支撑,从技术层面探讨云计算环境下数字图书馆的虚拟化,研究数字图书馆虚拟化资源在云计算环境中的集成与共享机制,进而创建一种云计算技术驱动下的数字图书馆虚拟化环境,为云计算时代虚拟化数字图书馆的组织模式作出探讨。

Abstract：

Considering the similar objectives of the cloud computing technology and virtual digital library,this paper takes the cloud computing technology as the basic support for constructing the virtual digital library,and discusses the virtualization of digital library in the cloud computing environment.The paper also studies the integrating and sharing mechanism of virtualized resources in digital library in the cloud computing environment,and furthermore constructs a virtualized environment for digital library driven by the cloud computing technology.Thus,the paper makes an exploration of the organization pattern of virtual digital library in the cloud computing era.     

基于虚拟地球的电离层电子密度时空多维可视化方法

针对多维多时相电离层电子密度数据在Web环境中传输困难而无法满足实时可视化需求以及传统面绘制方法无法反映原始数据场全貌的问题,从电离层电子密度源数据处理出发,使用视频压缩编码方法,实现时间序列数据的高效传输;借助WebGL可编程渲染管道,提出基于GPU加速的电离层电子密度光线投射体绘制方法,并采用自适应步长采样和早期光线终止法,提高可视化质量与体绘制效率;最后,基于开源虚拟地球平台Cesium,实现电离层电子密度的多层动态交互式可视化,验证所提方法的可行性和有效性,为电离层电子密度的科学可视化和辅助研究提供技术支持。     

Using & Re-using Archive Information for Multimedia Applications: The Virtual Museum of Italian Computer Science History

The quality of content is a key attribute for assessing the globalquality of a museum application. Unfortunately, producing good content,especially in multimedia digital form, is expensive and time-consuming.One way to reduce the costs without sacrificing quality is to exploitthe concept of information reuse. The idea is to use (portions of) thesame multimedia material in different applications, possibly adapting itfor different contexts, for different categories of users, and fordifferent delivery channels (e.g., on-line and off-line). Informationreuse does not come free. To be effective, it requires a well-organizedenvironment in which information can be easily stored, inspected,retrieved, and adapted for different purposes. This paper describes theapproach adopted in the project ``The Virtual Museum of Italian ComputerScience History', funded by the Italian National Council of Research(CNR). In this project, all the digital material (documents, images,video interviews, etc.) is stored in a digital archive based on amultimedia database with a WWW front-end. The archive is designed forspecialists only: members of the editorial board of the project;researchers in the history of science; application developers (whoare looking for interesting content to include in their CD-ROMs or Websites). Each research group involved in the project extracted andadapted from the digital archive the multimedia material needed to builda different hypermedia application in two ``versions' – WWW andCD-ROM. These applications, both on-line and off-line, strongly reuse(portions of) the digital archive content, but organize and present itwith a totally different style, to address the needs of non-specialists(e.g., people who have some interest, or curiosity, in the history ofItalian computer science).
