Liquid/solid phase change with convection and deformations: 2D case |
We present the results of the numerical simulation of the first stages of the melting from a side of a gallium slab by adding to the heat transfer and to the melt flow the description of the effects of the deformations of the solid phase. The experiment by Gau and Viskanta in [4] has been… | |
Subsoil decontamination with biological techniques: a bio-fluid dynamics problem |
A subsoil cleanup technology is called bioventing: bacteria are used to biodegrade pollutants and air is injected to enhance their activity. In this paper a general mathematical model describing the physical phenomenon is presented. The model is based on the theory of fluid dynamics in porous media… | |

Visual Investigation of Ancient Documents |
We present a work in progress about extracting words from images of historical printed documents by using fast marching method. Segmentation is a process that allows an image to be divided into disjoint zones, so that extracted areas contain homogeneous characteristics. The numerical method, we… | |

Lagrange Interpolation with Constraints on the Real Line |
We investigate the uniform convergence of Lagrange interpolation at the zeros of the orthogonal polynomials with respect to a Freud-type weight in the presence of constraints. We show that by a simple procedure it is always possible to transform the matrices of these zeros into matrices such that… | |
Mauro Picone e i primi progetti per un calcolatore italiano |
Storia dei maggiori progetti sviluppati da Mauro Picone per costruire in Italia un calcolatore elettronico prima della CEP. A questi progetti segue la collaborazione allo sviluppo della CEP tramite la realizzazione di un simulatore della calcolatrice pisana sulla Ferranti Mark 1* dell'INAC (FINAC… | |
Weighted uniform convergence of the quadrature method for Cauchy singular integral equations |
Collocation and quadrature methods for Cauchy singular integral equations on an interval with variable coefficients are studied. Convergence rates are proved in weighted uniform and uniform norms. | |
Coupling weakly-compressible SPH with Finite Volume Method: an algorithm for simulating free-surface flows |
An algorithm for coupling a classical Finite Volume (FV) approach, that discretize the Navier-Stokes equations on a block structured Eulerian grid, with the weakly-compressible SPH is presented. The coupling procedure aims at applying each solver in the region where its intrinsic characteristics… | |
Traffic Data Classification for Police Activity |
Traffic data, automatically collected en masse every day, can be mined to discover information or patterns to support police investigations. Leveraging on domain expertise, in this paper we show how unsupervised clustering techniques can be used to infer trending behaviors for road-users and thus… |
