Determination of unknown thermal coefficients in a Stefan problem for Storm’s type materials
(Sociedade Brasileira de Matemática Aplicada e Computacional, 2018-09)
We consider a nonlinear one-dimensional Stefan problem for a semi-infinite material x> 0 , with phase change temperature Tf. We assume that the heat capacity and the thermal conductivity satisfy a Storm’s condition. A ...
Determination of two unknown thermal coefficients through an inverse one-phase fractional Stefan problem
(De Gruyter, 2017-04)
We consider a semi-infinite one-dimensional phase-change material with two unknown constant thermal coefficients among the latent heat per unit mass, the specific heat, the mass density and the thermal conductivity. Aiming ...
Supercooled Stefan problem with a Neumann type boundary condition
(Texas State University, Department of Mathematics, 2020-05)
We consider a supercooled one-dimensional Stefan problem with a Neumann boundary condition and a variable thermal diffusivity. We establish a necessary and sufficient condition for the heat flux at the fixed face x = 0, ...
Note on a Parametric Relation for Separating Flow over a Rough Hill

Determination of One Unknown Thermal Coefficient through the One-Phase Fractional Lamé-Clapeyron-Stefan Problem
(Scientific Research Publishing, 2015-09)
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 through the one-phase fractional Lamé-Clapeyron-Stefan ...
Influence of the meridional overturning circulation on tropical Atlantic climate and variability
(AMER METEOROLOGICAL SOC, 2008)
The influence of the meridional overturning circulation on tropical Atlantic climate and variability has been investigated using the atmosphere-ocean coupled model Speedy-MICOM (Miami Isopycnic Coordinate Ocean Model). In ...
A preliminary simulation for the development of an implantable pulsatile blood pump
(Techno-press, 2014-06)
A preliminary study of a new pulsatile pump, that will work to a frequency greater than 1 Hz, is presented. The fluid-structure interaction between a Newtonian blood flow and a piston drive that moves with periodic speed ...
Delphi study to derive expert consensus on a set of criteria to evaluate discharge readiness for adult ICU patients to be discharged to a general ward — European perspective
(2022)
Background/purpose: Discharge decisions in Intensive Care Unit (ICU) patients are frequently taken under pressure to free up ICU beds. In the absence of established guidelines, the evaluation of discharge readiness commonly ...
Analytic solutions in the gauged skyrme model and conservation laws in gauge theories with applications to black hole mechanics.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Física., 2021)
The present thesis consists of two parts. Part I is devoted to the construction of
the first analytic examples of topologically non-trivial solutions of the U(1) gauged
Skyrme model within a finite box in (3 + 1)-dimensional ...
