Arquitectura en Valencia (1939-1957)
2011
Esta tesis doctoral recoge, a partir de una investigación exhaustiva, una panorámica de conjunto de la arquitectura realizada en la ciudad de Valencia entre 1939 y 1957. Los capítulos que contiene se estructuran fundamentalmente a partir de una clasificación por tipologías, a diferencia de los habituales estudios de Historia del Arte basados en los estilos artísticos, y en un amplio capítulo dedicado a la obra realizada por los arquitectos que trabajaron durante este periodo en Valencia, incorporando un pormenorizado listado de las obras que construyeron, organizadas cronológicamente, y aportando numerosa información documental inédita. Al finalizar la Guerra Civil en España, el nuevo Régim…
El primer tratado romano-cartaginés: análisis historiográfico y contexto histórico.
2009
El primer tratado romano-cartaginés constituye un tema de estudio controvertido sobre la Roma arcaica. Son las fuentes literarias las que informan al respecto, no otras. Polibio, Tito Livio y Diodoro constituyen las principales. El primero recoge un primer tratado al inicio de la República romana y la dedicación del templo Capitolino; el segundo cita una acuerdo entre romanos y cartagineses en los acontecimientos de 348 a.C., pero no dice expressis verbis que se trate del primero; Diodoro también señala un primer acuerdo en 348 a.C. Hay dos noticias más de la Antigüedad que conviene tener en cuenta a propósito de los acuerdos en cuestión, a saber: la mención de Aristóteles, en la Política, …
Las reliquias de la Capilla Real en la Corona de Aragón y el Santo Cáliz de la Catedral de Valencia (1396-1458)
2010
La tesis se divide en cuatro bloques que pretenden analizar el fenómeno de las reliquias en general y del Santo Cáliz en particular. El primero, más general, se centra en la historia de las reliquias a nivel internacional. La segunda parte es un análisis y estudio de la repercusión que los acontecimientos internacionales tenían en la devoción a las reliquias en la Península Ibérica. En el siglo IX se produce en la Península la aparición coincidente de las reliquias de Santiago de Compostela, las de San Isidoro de León y las de la Cámara Santa de la Catedral de Oviedo. Con ello España se integraba plenamente en la Cristiandad europea y en las rutas de peregrinación. Es entonces cuando aparec…

Timing of the emergence of the Europe-Sicily bridge (40-17 cal ka BP) and its implications for the spread of modern humans
2014
The submerged sill in the Strait of Messina, which is located today at a minimum depth of 81 m below sea level (bsl), represents the only land connection between Sicily and mainland Italy (and thus Europe) during the last lowstand when the sea level locally stood at about 126 m bsl. Today, the sea crossing to Sicily, although it is less than 4 km at the narrowest point, faces hazardous sea conditions, made famous by the myth of Scylla and Charybdis. Through a multidisciplinary research project, we document the timing and mode of emergence of this land connection during the last 40 kyr. The integrated analysis takes into consideration morphobathymetric and lithological data, and relative sea…

A test of transferability for landslides susceptibility models under extreme climatic events: application to the Messina 2009 disaster
2014
A model building strategy is tested to assess the susceptibility for extreme climatic events driven shallow landslides. In fact, extreme climatic inputs such as storms typically are very local phenomena in the Mediterranean areas, so that with the exception of recently stricken areas, the landslide inventories which are required to train any stochastic model are actually unavailable. A solution is here proposed, consisting in training a susceptibility model in a source catchment, which was implemented by applying the binary logistic regression technique, and exporting its predicting function (selected predictors regressed coefficients) in a target catchment to predict its landslide distribu…
Data Mining Technique (Maximum Entropy Model) for Mapping Gully Erosion Susceptibility in the Gorganrood Watershed, Iran
2019
Soil erosion is a serious problem affecting most of the countries. This study was carried out in Gorganrood Watershed (Iran), which extends for 10,197 km2 and is severely affected by gully erosion. A gully headcut inven- tory map consisting of 307 gully headcut points was provided by Google Earth images, field surveys, and national reports. Gully conditioning factors including sig- nificant geo-environmental and morphometric variables were selected as predictors. Maximum entropy (ME) model was exploited to model gully susceptibility, whereas the area under the ROC curve (AUC) and draw- ing receiver operating characteristic (ROC) curves were employed to evaluate the performance of the model.…
Hydrogeological hazards and weather events: Triggering and evolution of shallow landslides
2014
Abstract Landslides are the most intense and serious manifestations of the degradation of slopes and they are the main causes of geological hazard when they, directly or indirectly, involving towns and infrastructures. They are a global environment problem; there are several examples that have produced untold damages and loss of human lives in many parts of the world. In 1920 the landslides mobilization, as a result of a strong earthquake in China, in the province of Kansu, killed 200,000 people; in 1938 fast debris flow, triggered by heavy rainfalls in Japan, caused the death of 600 people; in 1963 in Italy the Vajont disaster caused the death of 1,899 people, as a result of a landslide lo…
Water erosion susceptibility mapping by applying Stochastic Gradient Treeboost to the Imera Meridionale River Basin (Sicily, Italy)
2016
Abstract Soil erosion by water constitutes a serious problem affecting various countries. In the last few years, a number of studies have adopted statistical approaches for erosion susceptibility zonation. In this study, the Stochastic Gradient Treeboost (SGT) was tested as a multivariate statistical tool for exploring, analyzing and predicting the spatial occurrence of rill–interrill erosion and gully erosion. This technique implements the stochastic gradient boosting algorithm with a tree-based method. The study area is a 9.5 km 2 river catchment located in central-northern Sicily (Italy), where water erosion processes are prevalent, and affect the agricultural productivity of local commu…
