GRIDA3—a shared resources manager for environmental data analysis and applications

GRIDA3 (Shared Resources Manager for Environmental Data Analysis and Applications) is a multidisciplinary project designed to deliver an integrated system to forge solutions to some environmental challenges such as the constant increase of polluted sites, the sustainability of natural resources usage and the forecast of extreme meteorological events. The GRIDA3 portal is mainly based on Web 2.0 technologies and EnginFrame framework. The portal, now at an advanced stage of development, provides end-users with intuitive Web-interfaces and tools that simplify job submission to the underneath computing resources. The framework manages the user authentication and authorization, then controls the action and job execution into the grid computing environment, collects the results and transforms them into an useful format on the client side. The GRIDA3 Portal framework will provide a problem-solving platform allowing, through appropriate access policies, the integration and the sharing of skills, resources and tools located at multiple sites across federated domains

Rilevamento e rappresentazione cartografica della variabilità spaziale dei suoli a differenti scale d'indagine: i casi studio di Monastir e del Foglio 549 Muravera

The considerable spatial variability of soils makes the possibility of making teoric models of survey and representation difficult. Nowadays, traditional surveys and others using the application of new technologies are still the best way to mark soils in a specific area. One main difference is that with the first methods, (openings of profiles, drillings, chemical analysis) is very expansive to do measurements in all the points of a particular site, and these expenditures are not sustainable by normal research centres and in general by public spending while, with the second methods there is a considerable reduction in prices. In the thesis's work the two different applied methodologies have been faced with different survey scale. In particular: with a very detailed scale the EMI (Induced ElectroMagnetism) technology has been used. This technology has the prerogative of being a forwarding method in mapping pedological variations, without any inconveniences neither to the structure nor to the dynamic character of the soil (Godwin and Miller, 2003; McBratney et al., 2003; Sommer et al., 2003). For the semi-detailed scale the area of Foglio Geologico Italia 549 - Muravera�is been chosen with a scale 1:50.000 Geopedological indications are from many executed profiles (66), and they have been used to value the spatial variability to a little scale and to represent with the Pedolandscape chart, with a scale of 1:50.000. The purpose is the management and visualization of obtained data in a synthetic way, and a geographic information system (GIS) is been predisposed to this
