Evaluación del significado cultural de un sitio histórico: Elca, la casa del poeta Francisco Brines
2022
El concepto de bien cultural con el tiempo se ha ido ampliando del monumento a su entorno, al territorio, y ha pasado de comprender elementos materiales a abarcar también los significados que se relacionan con el mismo. En este contexto cabe entender la figura de Sitio Histórico o lugar cultural, en la que se reconocen de forma preferente los valores inmateriales relacionados con un espacio sobre los elementos materiales, que pueden incluso llegar a resultar irrelevantes. Con motivo de la incoación de expediente para declarar la casa del poeta Francisco Brines como Bien de Interés Cultural (BIC) en la categoría de Sitio Histórico, hemos aplicado la metodología propuesta por la Carta de Burr…
Spectral study of {R, s + 1, k}- and {R, s + 1, k, *}-potent matrices
2020
[EN] The {R, s +1, k}- and {R, s +1, k, *}-potent matrices have been studied in several recent papers. We continue these investigations from a spectral point of view. Specifically, a spectral study of {R, s + 1, k} -potent matrices is developed using characterizations involving an associated matrix pencil (A, R). The corresponding spectral study for {R, s+ 1, k, *}-potent matrices involves the pencil (A*, R). In order to present some properties, the relevance of the projector I - AA(#). where A(#) is the group inverse of A is highlighted. In addition, some applications and numerical examples are given, particularly involving Pauli matrices and the quaternions.
Multi-criteria decision methods to support the maintenance management of complex systems
2019
[ES] Esta tesis doctoral propone el uso de métodos de toma de decisiones multi-criterio (MCDM, por sus iniciales en inglés) como herramienta estratégica para apoyar la gestión del mantenimiento de sistemas complejos. El desarrollo de esta tesis doctoral se enmarca dentro de un acuerdo de cotutela entre la Università degli Studi di Palermo (UNIPA) y la Universitat Politècnica de València (UPV), dentro de sus respectivos programas de doctorado en 'Ingeniería de Innovación Tecnológica' y 'Matemáticas'. Estos programas están estrechamente vinculados a través del tópico MCDM, ya que proporciona herramientas cruciales para gestionar el mantenimiento de sistemas complejos reales utilizando análisi…
Desajuste de trayectorias estudiantiles : caso comparativo de la Universidad Federal de Paraíba y la Universidad de València
2021
Este artículo aborda la cuestión del ajuste académico en las trayectorias universitarias entendiéndolo en base al ritmo de renovación de los estudiantes y de idoneidad de su rendimiento académico. El objetivo planteado es calibrar el ajuste entre ambos indicadores de rendimiento, es decir, renovación e idoneidad para poder proponer una medida integral de ajuste. Proponemos una metodología para ponderar el grado de ajuste en las trayectorias universitarias a partir de los indicadores de renovación e idoneidad mediante la propuesta de un nuevo indicador que denominamos tasa de ajuste. El procedimiento de su cálculo es a través de la adaptación del habitual índice de Gini y cuenta con la carac…

The economic impact of audit failures
2022
This paper examines the economic consequences associated with an audit failure in the field of statutory auditing services, by analyzing changes in the audit firm’s market share around the time of the investigation process undertaken by the Spanish Public Oversight Board. We explore the variations in audit market share by applying the difference in differences method to a treatment group of 70 sanctioned audit firms and a matched control group of 70 non-sanctioned audit firms. The period of analysis covers the years from 1999 to 2015. Our results show that the sanctioned audit firms suffered a significant decrease in their relative number of clients. Moreover, this measure of market share d…
Drift of the Earth’s Principal Axes of Inertia from GRACE and Satellite Laser Ranging Data
2020
The location of the Earth’s principal axes of inertia is a foundation for all the theories and solutions of its rotation, and thus has a broad effect on many fields, including astronomy, geodesy, and satellite-based positioning and navigation systems. That location is determined by the second-degree Stokes coefficients of the geopotential. Accurate solutions for those coefficients were limited to the stationary case for many years, but the situation improved with the accomplishment of Gravity Recovery and Climate Experiment (GRACE), and nowadays several solutions for the time-varying geopotential have been derived based on gravity and satellite laser ranging data, with time resolutions reac…
In vitro validation of biomedical polyester-based scaffolds: Poly(lactide-co-glycolide) as model-case
2018
[EN] Monitoring and understanding the in vitro behaviour of polyester based scaffolds both comprising the study of the hydrolytic degradation and the cell seeding viability is essential to ensure the desired functionality, according to a given biomedical purpose. As a model case to compare the performance of techniques to monitor the in vitro behaviour, poly(lactide-co-glycolide) (PLGA) scaffolds were chosen. The in vitro hydrolytic degradation of PLGA scaffolds was carried out in water and phosphate buffered saline (PBS). The evolution of the mass loss, the molar mass, the thermal properties and the surface morphology were monitored. The hydrolytic degradation media was correspondingly eva…
Management of uncertain pairwise comparisons in AHP through probabilistic concepts
2019
Abstract Fast and judicious decision-making is paramount for the success of many activities and processes. However, various degrees of difficulty may affect the achievement of effective and optimal solutions. Decisions should ideally meet the best trade-off among as many of the involved factors as possible, especially in the case of complex problems. Substantial cognitive and technical skills are indispensable, while not always sufficient, to carry out optimal evaluations. One of the most common causes of wrong decisions derives from uncertainty and vagueness in making forecasts or attributing judgments. The literature shows numerous efforts towards the optimization and modeling of uncertai…
