A Study on Collection Information for Discovery of Distributed Resources in Digital Libraries

Resource Discovery in Distributed Digital Libraries

In the near future, users will have access to a vast number of digital libraries. For a given information need and limited resources, there is the problem of selecting those libraries which produce an overall optimum answer. This resource discovery problem is additionally complicated by the diversity of the sources, e.g. with respect to media, document formats, indexing methods, database schema...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Interacting with information resources: digital libraries for education

This paper reviews the capabilities of libraries for supporting learning. We consider the various roles traditional libraries play and how they are being transformed into digital information repositories. Effective strategies for deploying digital libraries will retain the strengths of traditional libraries while exploiting new possibilities offered by the digital medium.

An Enhanced Search Interface for Information Discovery from Digital Libraries

Libraries, museums, and other organizations make their electronic contents available to a growing number of users on the Web. A large fraction of the information published is stored in structured or semi-structured form. However, most users have no specific knowledge of schemas or structured query languages for accessing information stored in (relational or XML) databases. Under these circumsta...
