A Lagrangian approach for solving an axisymmetric thermo-electromagnetic problem. Application to time-varying geometry processes
(Springer, 2024-05)[Abstract]: The aim of this work is to introduce a thermo-electromagnetic model for calculating the temperature and the power dissipated in cylindrical pieces whose geometry varies with time and undergoes large deformations; ... -
A low-order mixed finite element method for a class of quasi-Newtonian Stokes flows. Part I: a priori error analysis
(Elsevier BV, 2004-03)[Abstract] We present a mixed finite element method for a class of non-linear Stokes models arising in quasi-Newtonian fluids. Our results include, as a by-product, a new mixed scheme for the linear Stokes equation. The ... -
A low-order mixed finite element method for a class of quasi-Newtonian Stokes flows. Part II: a posteriori error analysis
(Elsevier BV, 2004-03)[Abstract] This is the second part of a work dealing with a low-order mixed finite element method for a class of nonlinear Stokes models arising in quasi-Newtonian fluids. In the first part we showed that the resulting ... -
A mixed finite element method for the generalized Stokes problem
(John Wiley & Sons Ltd., 2005-08-03)[Abstract] We present and analyse a new mixed finite element method for the generalized Stokes problem. The approach, which is a natural extension of a previous procedure applied to quasi-Newtonian Stokes flows, is based ... -
A Modal-Based Partition of Unity Finite Element Method for Elastic Wave Propagation Problems in Layered Media
(Elsevier, 2022)[Abstract] The time-harmonic propagation of elastic waves in layered media is simulated numerically by means of a modal-based Partition of Unity Finite Element Method (PUFEM). Instead of using the standard plane waves or ... -
A Modular Framework for Generic Quantum Algorithms
(MDPI, 2022)[Abstract] We describe a general-purpose framework to design quantum algorithms. This framework relies on two pillars: a basic data structure called quantum matrix and a modular structure based on three quasi-independent ... -
A new numerical method for pricing fixed-rate mortgages withprepayment and default options
(Taylor & Francis Online, 2016)[Abstract] In this paper we consider the valuation of fixed-rate mortgages including prepayment and default options,where the underlying stochastic factors are the house price and the interest rate. The mathematical modelto ... -
A New Technique for Improved Use of Thermal Energy from Waste Effluents
(MDPI AG, 2020-01-09)[Abstract] Energy sustainability and environmental protection in general are at the heart of engineering and industry discussions. Countless efforts have been devoted to improving the energy efficiency of industrial processes ... -
A Numerical Strategy for Telecommunications Networks Capacity Planning Under Demand and Price Uncertainty
(Elsevier BV * North-Holland, 2017-07)[Abstract] The massive use of Internet in the last twenty years has created a huge demand for telecommunications networks capacity. In this work, financial option pricing methods are applied to the problem of network ... -
A posteriori error analysis of an augmented mixed finite element method for Darcy flow
(Elsevier BV, 2015-01)[Abstract] We develop an a posteriori error analysis of residual type of stabilized mixed finite element method for Darcy flow. The stabilized formulation is obtained by adding to the standard dual-mixed approach suitable ... -
