Digital libraries are large, organized, focused collections of information. The Greenstone software is intended to help people design and build such collections quickly and easily. Collections may be large—some comprise Gbytes of text; others include many millions of short documents. Additionally, far larger volumes of information may be associated with a collection—typically audio, image, and ...

this study intended to carry out a survey of engineering college libraries that have computerized their operations and services. it provides an implicit view of the professional experiences of the engineering college librarians in computerizing their house keeping operations. information was collected using a structured questionnaire mailed to 128 engineering college librarians, of which 102 (7...

We examine the residual (measured minus internal) magnetic field vectors observed in Saturn’s magnetosphere during the Pioneer-11 fly-by in 1979, and compare them with those observed during the Voyager-1 and -2 flybys in 1980 and 1981. We show for the first time that a ring current system was present within the magnetosphere during the Pioneer-11 encounter, which was qualitatively similar to th...

Numerous software packages are being used and updated regularly on most computer systems. Installing all these software packages is a formidable task because each one has a different procedure for compiling or for placing the files required at run time. The LUDE (Logithèque Universitaire Distribuée et Extensible) software library is an organization for installing software packages, a set of too...

Circulation is one area of librarianship where each library can best demonstrate its individual nature as expressed through its policies. Whereas catalog librarians have shared standards and codes, acquisitions librarians have institutional rules and policies applied in standard business practices, and reference librarians must face each question with an established set of reference tools and p...

This paper studies ICMEs detected by both Voyager spacecraft during propagation from 1 to 10 AU, with observations 1977 1980. are using several signatures in the situ data, primary one being low measured expected proton temperature ratio. We found 21 events common and study their internal structure terms of plasma magnetic field properties. find that expanding as they propagate outwards, decrea...

This paper describes an implementation of intelligent, customizable mobile software agents for document classiication and retrieval. The mobile agents are implemented using the Voyager platform. The agents learn user's interests by interacting with the user. Results of experiments using three diier-ent approaches { TFIDF, Bayesian and DistAl (neural network classiier) { for the design of traina...
