This paper is focused on the urban edge detection topic, i.e. the identification of building and man made structures edges. An approach able to exploit jointly both the amplitudes and the interferometric phase of two complex SAR images is considered. This work is mainly focused on the application of this technique to real data sets. In particular, first experiments on COSMO-SkyMed data over the...

In the last years a new feature extraction approach from a single amplitude SAR image of urban areas has been introduced by the authors. In this paper they discuss the feasibility of this approach to detect changes in urban areas when natural hazards occur, with the aim to identify damaged or collapsed buildings by monitoring changes in the radiometric content of relevant SAR images. The test i...

The aim of these lectures is to give a brief introduction to brane cosmology. After introducing some basic geometrical notions, we discuss the cosmology of a brane universe with matter localized on the brane. Then we introduce an intrinsic curvature scalar term in the bulk action, and analyze the cosmology of this induced gravity. Finally we present the cosmology of a moving brane in the backgr...

The conformal equivalence between Jordan frame and Einstein frame can be used in order to search for exact solutions in general theories of gravity in which scalar fields are minimally or nonminimally coupled with geometry. In the cosmo-logical arena a relevant role is played by the time parameter in which dynamics is described. In this paper we discuss such issues considering also if cosmologi...

I present here a new algorithm to generate families of inhomogeneous mass-less scalar field cosmologies. New spacetimes, having a single isometry, are generated by breaking the homogeneity of massless scalar field G 2 models along one direction. As an illustration of the technique I construct cosmo-logical models which in their late time limit represent perturbations in the form of gravitationa...

A proton NMR method for the determination of the solvation numbers of alkaline earth cations with dimethylsulfoxide (DMSO) in nitromethane as diluent is described. The method is based on the monitoring of the resonance frequency of DMSO protons as a function of DMSO to metal ion mole ratio while keeping the metal ion concentration constant. The average solvation number of cations at any...

Lifelike animated agents for knowledge based learning en vironments can provide timely customized advice to support leaners problem solving activities By drawing on a rich repertoire of emotive behaviors to exhibit contextually appropriate facial expressions and emo tive gestures these agents could exploit the visual channel to more ef fectively communicate with learners To address these issues...

Preevent and event landslide deformations have been detected and measured for the landslide that occurred on 3 December 2013 on the south-western slope of the Montescaglioso village (Basilicata Region, southern Italy). In this paper, ground displacements have been mapped through an integrated analysis based on a series of high resolution SAR (Synthetic Aperture Radar) images acquired by the Ita...

Equilibrium in the electronic subsystem across the solution-metal interface is considered to connect the standard electrode potential to the statistics of localized electronic states in solution. We argue that a correct derivation of the Nernst equation for the electrode potential requires a careful separation of the relevant time scales. An equation for the standard metal potential is derived ...
