Numerical analysis of a family of optimal distributed control problems governed by an elliptic variational inequality
Mariela C. Olguin, Domingo A. Tarzia
The numerical analysis of a family of distributed mixed optimal control problems governed by elliptic variational inequalities (with parameter ) is obtained through the finite…
Double convergence of a family of discrete distributed mixed elliptic optimal control problems with a parameter
Domingo A. Tarzia
We consider a bounded domain in whose regular boundary consists of the union of two disjoint portions and with . The…
Determination of one unknown thermal coefficient through the one-phase fractional Lamé-Clapeyron-Stefan problem
Domingo Alberto Tarzia
We obtain explicit expressions for one unknown thermal coefficient (among the conductivity, mass density, specific heat and latent heat of fusion) of a semi-infinite material throu…
Simultaneous determination of two unknown thermal coefficients through a mushy zone model with an overspecified convective boundary condition
Andrea N. Ceretani, Domingo A. Tarzia
The simultaneous determination of two unknown thermal coefficients for a semi-infinite material under a phase-change process with a mushy zone according to the Solomon-Wilson-Alexi…
Existence, Uniqueness and Convergence of Simultaneous Distributed-Boundary Optimal Control Problems
Claudia M. Gariboldi, Domingo A. Tarzia
We consider a steady-state heat conduction problem for the Poisson equation with mixed boundary conditions in a bounded multidimensional domain . We also consider a family o…
Determination of one unknown thermal coefficient through a mushy zone model with a convective overspecified boundary condition
Andrea N. Ceretani, Domingo A. Tarzia
A semi-infinite material under a solidification process with the Solomon-Wilson- Alexiades's mushy zone model with a heat flux condition at the fixed boundary is considered. The as…
Modeling water uptake by a root system growing in a fixed soil volume
J. L. Blengino Albrieu, J. C. Reginato, D. A. Tarzia
The water uptake by roots of plants is examined for an ideal situation, with an approximation that resembles plants growing in pots, meaning that the total soil volume is fixed. We…
Explicit solutions for the Solomon-Wilson-Alexiades's mushy zone model with convective or heat flux boundary conditions
Domingo Alberto Tarzia
We complete the Solomon-Wilson-Alexiades's mushy zone model (Letters Heat Mass Transfer, 9 (1982), 319-324) for the one-phase Lamé-Clapeyron-Stefan problem. We obtain explicit solu…
A free boundary model for oxygen diffusion in a spherical medium
Adriana M. González, Juan C. Reginato, Domingo A. Tarzia
The goal of this article is to find a correct approximated solution using a polynomial of sixth degree for the free boundary problem corresponding to the diffusion of oxygen in a s…
