Most researchers would agree that research in the field of document processing can benefit tremendously from a common software library through which institutions are able to develop and share research-related software and applications across academic, business, and government domains. However, despite several attempts in the past, the research community still lacks a widely-accepted standard so...

The SLAM software package has been developed for appearance learning and matching problems in computational vision. Appearance learning involves use of principal component analysis for compression of a large input image set to a compact low-dimensional subspace, called the eigenspace, in which the images reside as parameterized manifolds. SLAM enables the user to obtain this parametric represen...

Lumped-conceptual rainfall-runoff models are a ‘stock in trade’ tool for those working in the water industry and allied fields. However, there are many alternative models available, and sometimes multiple implementations of the same model. The consequence of this is a plethora of models with different operational features and different access arrangements. Similarly, there are a variety of opti...

DSpace, Fedora, and Greenstone are three widely used open source digital library systems. In this paper we report on scalability tests performed on these tools by ourselves and others. These range from repositories populated with synthetically produced data to real world deployment with content measured in millions of items. A case study is presented that details how one of the systems performe...

In this article we present the Explanation Workbench, a library and tool for working with justification-based explanations of entailments in OWL ontologies. The workbench comprises a software library and Protégé plugin. The library can be used in standalone OWL API based applications that require the ability to generate and consume justifications. The Protégé plugin, which is underpinned by the...

This study is an examination of features of the four most popular digital library open source software packages against a set of predetermined criteria that is deemed to be essential for the development of a digital library. While analysing and identifying the similarities, differences, strengths, and weakness of the open source software packages, it is indicated that open source digital librar...

There art some library software systems available for large-scale libraries.in the market. For instance. MfNISIS [IDRC75] on HP3000, ATLAS [DRA76] on Vax8800, URICA [AWA78] on Microdata and VTLS [HP751 on HP3000. We introduce a small-scale library -circulation system, called ILRCS (Interactive Library Resources Circulation System). It has been designed and implemented on tht V~X/VMS 11-785 mini...

We investigate the problem of a collaborative digital library collection that allows librarians and non-librarians alike to share information on specific topics through MARC records. Many existing software tools for creating bibliographic records are not platform independent. Tools that are platform independent are integrated into library software and therefore cannot be used with any existing ...

The growing market of multi-media applications requires development of complex embedded systems with significant data-path portions. However, current hardware synthesis and software optimizations tools and methodologies do not support arithmeticlevel optimizations necessary for data intensive applications. In particular, most highlevel synthesis tools cannot automatically synthesize data paths ...

This paper describes the design and implementation of high performance numerical software in Java. Our primary goals are to characterize the performance of object-oriented numerical software written in Java and to investigate whether Java is a suitable language for such endeavors. We have implemented JLAPACK, a subset of the LAPACK library in Java. LAPACK is a high-performance Fortran 77 librar...
