During 10 years of activity at our Service, we collected 1867 cases of poisoning in children. Our observations concern only subjects hospitalized at our Institute and do not include phone call consultations. Our experience confirmed a higher number of poisonings among males. As far as age was concerned, the highest percentage of cases involved children(More)
In this paper we describe a parallel implicit method based on radial basis functions (RBF) for surface reconstruction. Practical applicability of RBF methods is hindered by their high computational demand, that requires the solution of linear systems of size equal to the number of data points. The implementation of our method relies on parallel scientific(More)
In this paper, starting from a real case of an art exhibit, we propose a mathematical model to simulate social network interactions of a visitor that shares his experience on a social network. The Integrate & Fire (I&F) model is used to reproduce the interest of spectators in a cultural heritage community. In our approach, visitor is modelled as a(More)
Computational kernel of the three-dimensional variational data assimilation (3D-Var) problem is a linear system, generally solved by means of an iterative method. The most costly part of each iterative step is a matrix-vector product with a very large covariance matrix having Gaussian correlation structure. This operation may be interpreted as a Gaussian(More)
