A finite-element numerical method to solve a weak formulation of quasi-linear parabolic problems on space-time domain governed by Burgers equation is given. Stability and errors estimates theorems for the numerical solution are proved for smooth init

In this paper, the characteristic-based split (CBS) algorithm is presented to solve water motion problem due to tides in the Venice lagoon. The basic equations are the well-known vertically integrated shallow-water equations expressed in terms of tot

We continue to investigate a family of fully discrete finite difference implicit methods already proposed for the numerical solution of one-dimensional hyperbolic systems of conservation laws. In this paper the extension of the Euler schemes to the r

A parallel solver for the adaptive finite element analysis is presented. The primary aim of this work has been to establish an efficient parallel computational procedure which requires only local computations to update the solution of the system of e

A time-frequency interpretation of the classical asymptotic theory of homogenization for elliptic PDE with periodic coefficients is presented and the relations with known multilevel/multiscale numerical schemes are investigated. We formulate a new fa

The flow perturbation around a circular rigid particle during simple shear deformation has been investigated for both Newtonian and non-Newtonian (power-law) fluids by finite-element modelling. If the particle is rotating under the applied shear coup

In this paper an Approximate Waves-Bordering algorithm (AWB) is presented. It computes the finite elements linear system solution-update after a refinement/unrefinement step. This is done taking into consideration only the equations that correspond t

The dynamics of shallow water has been studied and an algorithm for this dynamics has been developed. Results have been obtained with data of the Venice lagoon using a model made expressively by a semi‒implicit method based on a finite element meth
