Multipoint flux mixed finite element methods for slightly compressible flow in porous media
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper, we consider multipoint flux mixed finite element discretizations for slightly compressible Darcy flow in porous media. The methods are formulated on general meshes composed of triangles, quadrilaterals, ...
Short- and mid-term evaluation of the use of electric vehicles in urban freight transport collaborative networks: a case study
(Taylor & Francis, 2019)
info:eu-repo/semantics/article,
Despite its negative impacts, freight transportation is a primary component of all supply chains. Decision makers have considered diverse strategies, such as Horizontal Collaboration (HC) and the usage of alternative types ...
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
(Springer, 2019)
info:eu-repo/semantics/article,
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ...
Mixed-dimensional geometric multigrid methods for single-phase flow in fractured porous media
(SIAM, 2019)
info:eu-repo/semantics/article,
This paper deals with the efficient numerical solution of single-phase flow problems in fractured porous media. A monolithic multigrid method is proposed for solving two-dimensional arbitrary fracture networks with vertical ...
Numerical and experimental investigation of the stability of a drop in a single-axis acoustic levitator
(American Institute of Physics, 2019)
info:eu-repo/semantics/article,
Acoustic levitation can be employed to hold liquid drops in midair, enabling novel applications in X-ray scattering of proteins, amorphous crystallization of solutions, or contactless mixing. Multiple studies have characterized ...
Generalized forms of monotonicity in the data aggregation framework
(2019)
info:eu-repo/semantics/doctoralThesis,
El proceso de agregación trata el problema de combinar una colección de valores numéricos
en un único valor que los represente y las funciones encargadas de esta operación se denominan
funciones de agregación. A las ...
Efficient SSP low-storage Runge-Kutta methods
(2019)
Artículo / Artikulua,
In this paper we study the efficiency of Strong Stability Preserving (SSP) Runge-Kutta methods that can be implemented with a low number of registers using their Shu-Osher representation. SSP methods have been studied ...
Scale recoding in sociological research: a new validation methodology. An application to a political survey
(CSIC, 2019)
info:eu-repo/semantics/article,
La recodificación de variables es una etapa habitual en el análisis de datos de encuesta. No está exenta de riesgos, como pueden ser la introducción de sesgos o las posibles deformaciones de los datos originales. En este ...
Weak and directional monotonicity of functions on Riesz spaces to fuse uncertain data
(Elsevier B.V., 2019)
info:eu-repo/semantics/article,
In the theory of aggregation, there is a trend towards the relaxation of the axiom of monotonicity and also towards the extension of the definition to other domains besides real numbers. In this work, we join both approaches ...
Orness for real m-dimensional interval-valued OWA operators and its application to determine a good partition
(Taylor & Francis, 2019)
info:eu-repo/semantics/article,
Ordered Weighted Averaging (OWA) operators are a profusely applied class of averaging aggregation functions, i.e. operators that always yield a value between the minimum and the maximum of the inputs. The orness measure ...
