Upgrading Relational Legacy Data to eh Semantic Web

In this poster, we describe a framework composed of the R2O mapping language and the ODEMapster processor to upgrade relational legacy data to the Semantic Web. The framework is based on the declarative description of mappings between relational and ontology elements and the exploitation of such mapping descriptions by a generic processor capable of performing both massive and query driven data upgrade

R2O, an extensible and semantically based database-to-ontology mapping language

We present R2O, an extensible and declarative language to describe mappings between relational DB schemas and ontologies implemented in RDF(S) or OWL. R2O provides an extensible set of primitives with welldefined semantics. This language has been conceived expressive enough to cope with complex mapping cases arisen from situations of low similarity between the ontology and the DB models

Legal Ontologies for the spanish e-Government

The Electronic Government is a new field of applications for the semantic web where ontologies are becoming an important research technology. The e-Government faces considerable challenges to achieve interoperability given the semantic differences of interpretation, complexity and width of scope. In this paper we present the results obtained in an ongoing project commissioned by the Spanish government that seeks strategies for the e-Government to reduce the problems encountered when delivering services to citizens. We also introduce an e-Government ontology model; within this model a set of legal ontologies are devoted to representing the Real-estate transaction domain used to illustrate this paper

Probing the ZZgamma and Zgammagamma Couplings Through the Process e+e- --> nu anti-nu gamma

We study the sensitivity for testing the anomalous triple gauge couplings $ZZ\gamma$ and $Z\gamma\gamma$ via the process $e^+e^-\to \nu \bar\nu \gamma$ at high energy linear colliders. For integrated luminosities of 500 $fb^{-1}$ and center of mass energies between 0.5 and 1.5 $TeV$, we find that this process can provide tests of the triple neutral gauge boson couplings of order $10^{-4}$, one order of magnitude lower than the standard model prediction.Comment: 12 pages, 6 figure

Photon Redshift in a Magnetic field

Previous results from the authors concerning the arising a tiny photon anomalous paramagnetic moment are also interpreted as a red-shift in analogy to the gravitational known effect. It is due to the photon interaction with the magnetized virtual electron-positron background which withdraw transverse momentum from photons and is polarization-dependent. If the photon frequency red-shift implies a change in time, a clock would go faster for increasing magnetic field intensity

On the relation between the IR continuum and the active galactic nucleus in Seyfert galaxies

A sample of the brightest known Seyfert galaxies from the CfA sample is analyzed on the basis of ISO photometric and spectroscopic data. Regardless of the Seyfert type, the mid-IR continuum emission from these galaxies is found to be correlated with the coronal line emission arising in the nuclear active region. Conversely, the correlation degrades progressively when moving from the mid- to the far-IR emission, where it ends to vanish. It is concluded that the mid-IR emission is largely dominated by dust heated by processes associated with the active nucleus whereas the far-IR is a different component most probably unrelated with the active region. We suggest that the far-IR component is due to dust heated by the stellar population in the disks of these galaxies.Comment: 6 pages, 3 figures To be published in Astronomy and Astrophysic

Bajo la sombra de don Luis de Requesens: el encumbramiento cortesano del Marqués de los Vélez

Este artículo pretende profundizar en el conocimiento de la corte de Felipe II, merced a la correspondencia que mantuvieron Luis de Requesens y su yerno, el III marqués de los Vélez, entre 1572 y 1575. El servicio al rey se muestra como el verdadero trampolín de la aristocracia hispánica, pero para acceder a los puestos de relevancia en la administración y al espacio áulico era conveniente y casi necesario estar emparentado con algún ilustre linaje. El brillante y vertiginoso cursus honorum de don Pedro Fajardo, merced al apoyo de su suegro, ilustra acerca de procesos de movilidad social ascendente, alianzas políticas y familiares. Lo privado y lo público se entremezclan en beneficio de las ambiciones de unos nobles que persiguen su propio éxito no como fin en sí mismo, sino para el aumento del prestigio de su casa.This article aims to deep the knowledge of the court of Philip II, through the correspondence that kept Luis Requesens and his son in law, the third Marquis of los Vélez, between 1572 and 1575. The service to the king is shown as the springboard of Hispanic aristocracy, but to attain positions of prominence in the administration and palatine space was suitable and almost necessary to be related to some iIIustrious lineage. The brilliant and dizzying cursus honorum of Don Pedro Fajardo, with the support of his father in law, illustrates about processes of upward social mobility, political and covenants family. The private and the public are intertwined to the benefit of the ambitions of nobles who pursue their own success rather than an end in itself, but for increased the prestige of his household
