Multilayer models for hydrostatic Herschel-Bulkley viscoplastic flows
(Elsevier, 2023)
Starting from Navier-Stokes’ equation we derive two shallow water multilayer models for yield stress fluids, depending on the asymptotic analysis. One of them takes into account the normal stress contributions, making ...
Non-hydrostatic layer-averaged approximation of Euler system with enhanced dispersion properties
(Springer, 2023)
A new family of non-hydrostatic layer-averaged models for the non-stationary Euler equations is presented in this work, with improved dispersion relations. They are a generalisation of the layer-averaged models introduced ...
Shallow Water Moment Models for Bedload Transport Problems
(Global Science Press, 2021)
In this work a simple but accurate shallow model for bedload sediment transport is proposed. The model is based on applying the moment approach to the Shallow Water Exner model, making it possible to recover the vertical ...
Flexible and efficient discretizations of multilayer models with variable density
(Elsevier, 2021)
We show that the semi-implicit time discretization approaches previously introduced for multilayer shallow water models for the barotropic case can be also applied to the variable density case with Boussinesq approximation. ...
A general vertical decomposition of Euler equations: Multilayer-moment models
(Elsevier, 2023)
In this work, we present a general framework for vertical discretizations of Euler equations. It generalizes the usual moment and multilayer models and allows to obtain a family of multilayer-moment models. It considers a ...
Multilayer Shallow Model for Dry Granular Flows with a Weakly Non-hydrostatic Pressure
(Springer, 2023)
The multilayer model proposed in this paper is a generalization of the multilayer non-
hydrostatic model for shallow granular flows (Fernández-Nieto et al in Commun Math Sci

Effects of an Interventional Music Program on Linguistic Skills of Primary-School Students with Dyslexia
(Conscientia Beam, 2021)
Research has shown that children with dyslexia have difficulties perceiving rhythm, and that musical training can enhance their learning skills. The purpose of this research was to investigate the effectiveness of an ...
Análisis bibliométrico de la producción de tesis doctorales sobre traducción e interpretación en las universidades españolas (1997-2018)
(Universidad de Murcia, 2020)
Se presenta un estudio bibliométrico de las tesis doctorales sobre Traducción e Interpretación realizadas en España e indexadas en la base de datos TESEO. Se recuperaron 389 tesis doctorales. Se pretende realizar un estudio ...
On the connectedness of a random closed set of a Euclidean space
(Elsevier, 2022)
Our aim is to obtain a suitable characterization of certain topological properties of a random closed set through its capacity
functional. The main technique mixes two different fields: on the one hand, the abstract ...
La resolución de problemas basada en el método de Polya usando el pensamiento computacional y Scratch con estudiantes de Educación Secundaria
(Universidad de Oviedo, 2020)
La inclusión de la tecnología como recurso educativo supone un nuevo escenario de trabajo en el aula que requiere de un proceso de investigación empírica para valorar su efectividad. El presente trabajo consiste en un ...
