Non-industrialized countries desiring to provide patent documentation and information services should seek cooperation with countries having similar backgrounds to form a regional patent documentation and information centre. This centre should supply bibliographic patent information, copies of patent documents, SDI services, state-of-the-art searches and novelty searches.A paper based patent collection is not feasible in view of the workload involved (more than 300 man-yr) and the necessary storage capacity (15 km of paper documents). Consequently microform and EDP facilities should be used whenever convenient.To provide information on patent documents of the member countries a centralized bibliographic data base and a complete collection of patent documents in microform should be established. Information on patent documents of other countries should be obtained from existing worldwide bibliographic data bases, and from search files existing elsewhere.Patent collections in microform of the most important countries should be acquired and for certain fields of high regional interest inhouse search files could be established.  相似文献

目前,数码相机采用的存储格式主要有RAW、JPEG、TIFF。相机的传感器在曝光后获得的信息可以保持原始状态存储在存储卡中,形成RAW格式文件,以后再用专门软件处理,也可以直接在相机内经机内软件处理形成JPEG或TIFF格式文件的图像。后二种方法比较快捷,但有时会损失一些影像细节;而以RAW格式存储的拍摄数据经专门软件后处理,往往可以获得一些有用的影像细节,对痕迹物证照相很有价值;本文对此简明阐述。  相似文献

With the development of information technology, cloud computing technology has brought many conveniences to all aspects of work and life. With the continuous promotion, popularization and vigorous development of e-government and e-commerce, the number of documents in electronic form is getting larger and larger. Electronic document is an indispensable main tool and real record of e-government and business activities. How to scientifically and effectively manage electronic documents? This is an important issue faced by governments and enterprises in improving management efficiency, protecting state secrets or business secrets, and reducing management costs. This paper discusses the application of cloud computing technology in the construction of electronic file management system, proposes an architecture of electronic file management system based on cloud computing, and makes a more detailed discussion on key technologies and implementation. The electronic file management system is built on the cloud architecture to enable users to upload, download, share, set security roles, audit, and retrieve files based on multiple modes. An electronic file management system based on cloud computing can make full use of cloud storage, cloud security, and cloud computing technologies to achieve unified, reliable, and secure management of electronic files.  相似文献

The paper presents a methodology called hybrid documents co-citation analysis, for studying the interaction between science and technology in technology diffusion. Our approach rests mostly on patent citation, cluster analysis and network analysis. More specifically, with the patents citing Smalley RE in Derwent innovations index as the data sets, the paper implemented hybrid documents co-citation network through two procedures. Then spectrum cluster algorithm was used to reveal the knowledge structure in technology diffusion. After that, with the concordance between network properties and technology diffusion mechanisms, three indicators containing degree, betweenness and citation half-life, were calculated to discuss the basic documents in the pivotal position during the technology diffusion. At last, the paper summarized the hybrid documents co-citation analysis in practise, thus concluded that science and technology undertook different functions and acted dominatingly in the different period of technology diffusion, though they were co-activity all the time.  相似文献

This paper analyzes the relationship among research collaboration, number of documents and number of citations of computer science research activity. It analyzes the number of documents and citations and how they vary by number of authors. They are also analyzed (according to author set cardinality) under different circumstances, that is, when documents are written in different types of collaboration, when documents are published in different document types, when documents are published in different computer science subdisciplines, and, finally, when documents are published by journals with different impact factor quartiles. To investigate the above relationships, this paper analyzes the publications listed in the Web of Science and produced by active Spanish university professors between 2000 and 2009, working in the computer science field. Analyzing all documents, we show that the highest percentage of documents are published by three authors, whereas single-authored documents account for the lowest percentage. By number of citations, there is no positive association between the author cardinality and citation impact. Statistical tests show that documents written by two authors receive more citations per document and year than documents published by more authors. In contrast, results do not show statistically significant differences between documents published by two authors and one author. The research findings suggest that international collaboration results on average in publications with higher citation rates than national and institutional collaborations. We also find differences regarding citation rates between journals and conferences, across different computer science subdisciplines and journal quartiles as expected. Finally, our impression is that the collaborative level (number of authors per document) will increase in the coming years, and documents published by three or four authors will be the trend in computer science literature.  相似文献
