Aplicación del sistema de informacion arqueológica SIDGEIPA a la gestión de la excavación de urgencia del yacimiento la Colata (Montavener, Valencia)
2003
La aplicación del programa Sidgeipa en la excavación de urgencia realizada en el yacimiento de La Colata (Montaverner, Valencia), ha permitido documentar de forma rápida y fiable, casi un centenar de estructuras negativas, de diversa tipología y atribución cronológica. Una de las características más eficaces de Sidgeipa reside en su capacidad para almacenar, de forma razonable, la gran cantidad de datos generados en la excavación, las coordenadas tridimensionales de todas las estructuras registradas, los materiales hallados en el interior de sus rellenos (incluidos los individuos enterrados) y toda la información correspondiente a las Unidades Estratigráficas que hayan sido distinguidas. La…
Emulation of Sun-Induced Fluorescence from Radiance Data Recorded by the HyPlant Airborne Imaging Spectrometer
2021
The retrieval of sun-induced fluorescence (SIF) from hyperspectral radiance data grew to maturity with research activities around the FLuorescence EXplorer satellite mission FLEX, yet full-spectrum estimation methods such as the spectral fitting method (SFM) are computationally expensive. To bypass this computational load, this work aims to approximate the SFM-based SIF retrieval by means of statistical learning, i.e., emulation. While emulators emerged as fast surrogate models of simulators, the accuracy-speedup trade-offs are still to be analyzed when the emulation concept is applied to experimental data. We evaluated the possibility of approximating the SFM-like SIF output directly based…

Niche position drives interspecific variation in occupancy and abundance in a highly-connected lake system
2019
Highlights • We studied interspecific variation in occupancy and abundance of freshwater species. • Occupancy and abundance correlated positively for both diatoms and macroinvertebrates. • Niche position had clearest effects on variation in occupancy and abundance. • The more marginal the niche position, the rarer a species is. We examined how niche position, niche breadth, biological traits and taxonomic relatedness affect interspecific variation in occupancy and abundance of two commonly-used biological indicator groups, i.e. diatoms and macroinvertebrates. We studied 291 diatom and 103 macroinvertebrate species that occupied the littoral zones of a large (305 km2) highly-connected freshw…
UPTAKE OF SILICA COVERED QUANTUM DOTS ON LIVING CELLS: LONG TERM VITALITY AND MORPHOLOGY STUDY ON HYALURONIC ACID BIOMATERIALS
2015
In this work we prepared colloidal CdSe-CdS core-shell nanocrystal emitting @625 nm and, by a micro-emulsion procedure of water in oil inverse micelle, we encapsulated a single dot inside each silica sphere. In this way the nanoparticles became biocompatible, are simply to prepare and could be used also in a water based environment. Moreover, the silica shield is transparent to the wavelengths of interest.
Recovering Sicilian Silk Heritage through Digital Technologies: The Case of Piraino’s Collection
2022
Textile conservation has given rise to small and medium-sized museums, usually with scarce resources. In Sicily, the little evidence that remains of silk production and opulent imports by the rich and powerful local aristocracy is kept in museums, parishes, and other cultural institutions. The documentation, dissemination, and enhancement of such a fragile heritage is today possible by means of technological tools that provide novel means to preserve, analyze, and exploit digital information. In this paper, we present some outcomes of the SILKNOW project, a project that applies computing research to the needs of diverse users (museums, educational institutions, the tourism industry, creativ…
Presència virtual de les universitats andaluses
2009
En aquest article exposarem de manera específica les iniciatives portades a terme en les universitats andaluses per fomentar, reforçar i estendre la seva presència virtual a la xarxa. Farem un recorregut pels serveis inculats amb la tecnologia i suport a l'ensenyament, els campus i aules virtuals presents en cadascuna d'aquestes universitats, així com pels esforços realitzats per La xarxa d'Universitats Virtuals Andaluzas per a la creació i desenvolupament del Campus Virtual Andaluz del qual formen part totes les universitats andaluses a través d'una àmplia oferta d'activitats d'ensenyament en línia.
Analysis and evaluation of the inclusive model in infant and primary centre support systems
2016
En esta investigación se analiza el funcionamiento y la organización de los sistemas de apoyo utilizados en centros de Educación Infantil y Primaria de la Comunidad Valenciana. Planteamos hasta qué punto los sistemas de apoyo en estos centros contribuyen a mejorar la organización de un sistema inclusivo que resulte accesible para todos. En el estudio de casos han participado 24 profesionales pertenecientes a cuatro centros que tienen diferentes modalidades de escolarización. Para la recogida de información, se han manejado instrumentos cualitativos como son la entrevista, la observación y el análisis documental. Según los datos obtenidos, los sistemas de apoyo no se ajustan de forma integra…
Tecnologías de información y contabilidad de gestión: evidencia empírica de la autoridad portuaria de Valencia
2008
Ports that have good geographical location, efficient management and value-added services have potential for international leadership, as is the case with the Valencia Port Authority, which figures prominently in the international ranking of container ports. Information systems should stimulate the curiosity of organizations, facilitate the process of participatory decision-making and enhance the ability of the organization to cope with changes in the environment. Changes occurring in the environment fully affect the organization and therefore its computer systems. Through the study of the Business Intelligence Systems at the Valencia Port Authority, we seek to reaffirm the assumptions of t…
