An overview of some mathematical techniques and problems linking 3D vision to 3D printing |
Computer Vision and 3D printing have rapidly evolved in the last 10 years but interactions among them have been very limited so far, despite the fact that they share several mathematical techniques. We try to fill the gap presenting an overview of some techniques for Shape-from-Shading problems as… | |

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… |
