De errores y erratas. Cómo corregir y normalizar un texto académico

2012

En el presente artículo, se intenta demostrar en primer lugar, a partir de ejemplos de una revista académica de lingüística, que errores y erratas tienen el mismo protagonismo en la corrección de textos académicos. Pero además, que los criterios y procedimientos de normalización – definida como el conjunto de decisiones y de procedimientos que tienden a unificar el estilo de un escrito en todos sus niveles– son fundamentales para que un conjunto de artículos científicos de autores varios o una serie de trabajos de un mismo autor, de distinto tema o etapas académicas, puedan llegar a convertirse en una publicación periódica o en un libro. In the present article, we first intend to demonstrat…

La forma de gobierno en la Constitución de Cádiz (reflexiones sobre la configuración de la Jefatura del Estado monárquica)

2012

A partir de las circunstancias históricas de las Cortes de Cádiz y de los precedentes de la monarquía española, el artículo analiza la posición de la Jefatura del Estado monárquica en la Constitución de 1812 caracterizada como una «Monarquía moderada» basada en los principios estructurales de soberanía nacional y división de poderes que determinan la configuración del Rey como poder constituido en la nueva forma de gobierno. La afirmación de la soberanía nacional impregna el conjunto del texto constitucional sin perjuicio de que coexista retóricamente con la antigua legitimidad monárquica. Por otra parte, la división de poderes supone la distinción entre la titularidad de la soberanía y su …

Removing the saturation assumption in Bank-Weiser error estimator analysis in dimension three

2020

International audience; We provide a new argument proving the reliability of the Bank-Weiser estimator for Lagrange piecewise linear finite elements in both dimension two and three. The extension to dimension three constitutes the main novelty of our study. In addition, we present a numerical comparison of the Bank-Weiser and residual estimators for a three-dimensional test case.

Correlative study of structural and optical properties of ZnSe under severe plastic deformation

2019

The effect of plastic deformation on the optical and structural properties of ZnSe crystals has been investigated. The optical properties have been monitored by cathodoluminescence measurements as a function of the deformation degree. Remarkable differences in the defect-related emissions from the most severely deformed areas have been encountered. Deformation of the crystal lattice of ZnSe, associated with slip phenomena, has been studied by means of Electron Backscattered Diffraction and micro-Raman spectroscopy. The relation between the deformation and the optical properties of the ZnSe crystals has been described.

Data-driven Fault Diagnosis of Induction Motors Using a Stacked Autoencoder Network

2019

Current signatures from an induction motor are normally used to detect anomalies in the condition of the motor based on signal processing techniques. However, false alarms might occur if using signal processing analysis alone since missing frequencies associated with faults in spectral analyses does not guarantee that a motor is fully healthy. To enhance fault diagnosis performance, this paper proposes a machinelearning based method using in-built motor currents to detect common faults in induction motors, namely inter-turn stator winding-, bearing- and broken rotor bar faults. This approach utilizes single-phase current data, being pre-processed using Welch’s method for spectral density es…

Space‐vector state dynamic model of SynRM considering self‐ and cross‐saturation and related parameter identification

2020

This study proposes a state formulation of the space-vector dynamic model of the Synchronous Reluctance Motor (SynRM) considering both saturation and cross-saturation effects. The proposed model adopts the stator currents as state variables and has been theoretically developed in both the rotor and stator reference frames. The proposed magnetic model is based on a flux versus current approach and relies on the knowledge of 11 parameters. Starting from the definition of a suitable co-energy variation function, new flux versus current functions have been initially developed, based on the hyperbolic functions and, consequently, the static and dynamic inductance versus current functions have be…
