GeoNET: WebGIS of a GNSS Permanent Network

2009

In Sicily, from 2005 to 2007, a research group at the Dipartimento di Rappresentazione, DIRAP (University of Palermo) has realized a Global Navigation Satellite System (GNSS) network for real time positioning (Network Real Time Kinematic –NRTK), activity founded by “Minister of Instruction, University and Scientific Research” (MIUR) as “National Interest Research Program” PRIN2005 entitled "Networks of permanent GPS stations for the survey in real time control and use of emergency". The data-base contains different kind of information both general on the network and positional. Positional information can be useful for two types of survey applications: static survey with post-processing of d…

Critical analysis of thermal inertia approaches for surface soil water content retrieval

2013

The “thermal inertia” method to retrieve surface soil water content maps on bare or sparsely-vegetated soils is analysed. The study area is a small experimental watershed, where optical and thermal images (in day and night time) and in situ data were simultaneously acquired. The sensitivity of thermal inertia to the phase difference between incoming radiation and soil temperature is demonstrated. Thus, to obtain an accurate value of the phase difference, the temporal distance between thermographs using a three-temperature approach is evaluated. We highlight when a cosine correction of the temperature needs to be applied, depending on whether the thermal inertia formulation includes two gene…

Higher-order Hamilton–Jacobi perturbation theory for anisotropic heterogeneous media: dynamic ray tracing in Cartesian coordinates

2018

With a Hamilton–Jacobi equation in Cartesian coordinates as a starting point, it is common to use a system of ordinary differential equations describing the continuation of first-order derivatives of phase-space perturbations along a reference ray. Such derivatives can be exploited for calculating geometrical spreading on the reference ray and for establishing a framework for second-order extrapolation of traveltime to points outside the reference ray. The continuation of first-order derivatives of phase-space perturbations has historically been referred to as dynamic ray tracing. The reason for this is its importance in the process of calculating amplitudes along the reference ray. We exte…

Definition of a Workflow for Web Browsing of 3D Models in Archaeology

2016

The Cultural Heritage (CH) is a fundamental element of promotion of territories and of tourism development. Publishing 3D models of archaeological sites and their three-dimensional reconstruction on the Web is one of the best ways to spread their knowledge. However, many recent scientific researches in this field have highlighted the limitations and difficulties related to the networking of interactive 3D models. The main difficulties are related to the complexity and the size of models, which influence the access speed, and the cost of software and hardware needed for the publication on the WEB. In light of this background, this article describes the further advances of research activities…

Mente, substancia y contexto

1993

Tras unas observaciones relativamente amplias sobre el peculiar estilo filosófico de Wittgenstein, así como acerca de la clara separación que el filósofo vienés establece entre la filosofía y las ciencias empíricas (frente a la continuidad entre ambas promovida por la filosofía naturalizada), este trabajo se adentra en la filosofía wittgensteiniana de la mente, fuertemente opuesta al cartesianismo. El aspecto central de este es la concepción de lo mental en términos de substancia: el cartesianismo subraya la independencia ontológica y epistemológica de lo mental frente a cualquier otra entidad o realidad. Esta concepción substancial de lo mental constituye el núcleo central del cartesianism…

Fault Lines: how hidden fractures still threaten the World Economy

2017

¿Por qué sucede la crisis económica de 2008? ¿fue provocada por los Estados Unidos como una estrategia expansionista o una simple falla del sistema capitalista? En perspectiva, el mundo de las relaciones productivas impacta sobre el social y viceversa. No es extraño observar el interés de las ciencias sociales por el estudio del riesgo en los últimos años. Para los especialistas, el riesgo se corresponde con la probabilidad de sufrir algún daño a futuro...

Spatial Bayesian Modeling Applied to the Surveys of Xylella fastidiosa in Alicante (Spain) and Apulia (Italy)

2020

The plant-pathogenic bacterium Xylella fastidiosa was first reported in Europe in 2013, in the province of Lecce, Italy, where extensive areas were affected by the olive quick decline syndrome, caused by the subsp. pauca. In Alicante, Spain, almond leaf scorch, caused by X. fastidiosa subsp. multiplex, was detected in 2017. The effects of climatic and spatial factors on the geographic distribution of X. fastidiosa in these two infested regions in Europe were studied. The presence/absence data of X. fastidiosa in the official surveys were analyzed using Bayesian hierarchical models through the integrated nested Laplace approximation (INLA) methodology. Climatic covariates were obtained from …

Évaluation de la réserve en eau à l'échelle des pédopaysages de Bourgogne

2009

National audience; L'étude porte sur l'adaptation au changement climatique en Bourgogne. Elle vise à définir la sensibilité de la ressource en eau des territoires Bourguignons à ces évolutions climatiques et à en estimer les incidences par secteurs géographiques et d'activité. Ce projet pluri-disciplaire a été mis en place par Alterre Bourgogne dont la tache a été de fédérer un réseau d'acteurs régionaux aux compétences variées : climatologie, pédologie et hydrologie. La première étape, présentée ici, a consisté à estimer la capacité des sols à stocker de l'eau, c'est-à-dire à calculer la taille de leur réserve utile. Ces calculs ont été réalisés à partir du référentiel pédologique de Bourg…
