Case study for the management of a set of spectrally analyzed signals based on OODBMS
(1997)This paper is a case study for the management of a set of synthetic harmonic and real-world sampled signals analyzed by various spectral methods at some desired orders. An OODBMS schema was preferred to an alternative ... -
Considerations On Low Complexity Codes Concerning Symmetry And Cyclicity
The binary error correcting codes that are examined in this paper are codes which are constructed out of shorter subcodes. The method of construction is well described by a bipartite graph. The one set of nodes of this ... -

Mapping Derivative Relationships from RDA to BIBFRAME 2
(2019)Semantic interoperability between Resource Description and Access (RDA) and BIBFRAME models is of great interest to the library community. In this context, this work investigates the mapping of core entities, inherent and ... -
Methodology of analysis and interrelation of data about quality indexes of library services by using data- and knowledge- mining techniques
(2009)Purpose - This paper aims to describe a data analysis methodology using data- and knowledge-mining techniques focused on libraries. It concerns data analysis techniques in general, as well as ways in which they could be ... -
Name and Title Authorities in the Music Domain: alignment of UNIMARC Authorities Format with RDA
(2017)This article discusses and highlights alignment issues that arise between UNIMARC Authorities Format and Resource Description and Access (RDA) regarding the creation of name and title authorities for musical works and ... -
On rewriting Xpath Queries Using Views
(2009)The problem of rewriting a query using a materialized view is studied for a well known fragment of XPath that includes the following three constructs: wildcards, descendant edges and branches. In earlier work, determining ... -
On solving efficiently the view selection problem under bag-semantics
(2009)In this paper, we investigate the problem of view selection for workloads of conjunctive queries under bag semantics. In particular we aim to limit the search space of candidate viewsets. In that respect we start delineating ... -
Representing and integrating bibliographic information into the Semantic Web: a comparison of four conceptual models
(2017)Integration of library data into the Semantic Web environment is a key issue for libraries and is approached on the basis of interoperability between conceptual models. Several data models exist for the representation and ... -
Storing multidimensional XML documents in relational databases
(2007)The problem of storing and querying XML data using relational databases has been considered a lot and many techniques have been developed. MXML is an extension of XML suitable for representing data that assume different ... -
A value-propagating transformation technique for Datalog programs based on non-deterministic constructs
(2006)The branching-time transformation is a recent technique for optimizing Chain Datalog programs. In this paper we propose a significant extension of the branching-time transformation which we believe opens up a promising new ...
