Evaluating open access journals using Semantic Web technologies and scorecards

This paper describes a process to develop and publish a scorecard from an OAJ (Open Access Journal) on the Semantic Web using Linked Data technologies in such a way that it can be linked to related datasets. Furthermore, methodological guidelines are presented with activities related to each step of the process. The proposed process was applied to a university OAJ, including the definition of the KPIs (Key Performance Indicators) linked to the institutional strategies, the extraction, cleaning and loading of data from the data sources into a data mart, the transformation of data into RDF (Resource Description Framework), and the publication of data by means of a SPARQL endpoint using the Virtuoso software. Additionally, the RDF data cube vocabulary has been used to publish the multidimensional data on the Web. The visualization was made using CubeViz, a faceted browser to present the KPIs in interactive charts.This research was supported by National Polythecnic School of Quito, Ecuador.

Las tecnologías de Linked Data y sus aplicaciones en el gobierno electrónico

The Open Access Initiative primary encourages state agencies to publish their data as soon as possible. Linked Data Technologies help in this direction. This article introduces concepts and tools that can help to implement projects of Linked Data, as well as some applications in e-Government. Our goal is to provide an overview of this new area and its potential use in the e-Gov field particularly. To achieve a successful implementation at a large scale, some prerrequisites must be ensured: developing methodologies to generate and publish Linked Data faithfully and economically, ensuring the persistence of links and sources, developing standards on recording metadata from this sources, ensuring data privacy, security and preservation, and developint tools to effectively and efficiently retrieve, display and navigate Linked Data.Los movimientos de acceso abierto impulsan a los organismos principalmente estatales a publicar sus datos lo más pronto posible. Las tecnologías de Linked Data ayudan en esta dirección. En este artículo se presentan conceptos y herramientas que pueden ser útiles para implementar proyectos de Linked Data, así como también algunas aplicaciones al gobierno electrónico. Nuestro objetivo es proporcionar una visión general de esta nueva área y su potencial uso, particularmente en el ámbito del gobierno electrónico. Para una implementación a gran escala es necesario desarrollar metodologías para generar y publicar Linked Data en la Web, desarrollar algoritmos para interconectar datos automáticamente, asegurar la pervivencia de los enlaces, desarrollar estándares para registrar información de las fuentes de datos, asegurar la privacidad, seguridad y preservación de los datos generados, crear herramientas para facilitar la búsqueda y despliegue de Linked Data

Modelling nanoparticles formation in the plasma plume induced by nanosecond pulsed lasers

Nanoparticles formation in a laser-induced plasma plume in the ambient air has been investigated by using numerical simulations and physical models. For high irradiances, or for ultrashort laser pulses, nanoparticles are formed by condensation, as fine powders, in the expanding plasma for very high pairs of temperature and pressure. At lower irradiances, or nanosecond laser pulses, another thermodynamic paths are possible, which cross the liquid-gas transition curve while laser is still heating the target and the induced plasma. In this work, we explore the growth of nanoparticles in the plasma plume induced by nanosecond pulsed lasers as a function of the laser irradiance. Moreover, the influence of the ambient gas has also been investigated
