The effect of through-thickness compressive stress on mode II interlaminar fracture toughness
2017
Abstract The effect of through-thickness compressive stress on mode II interlaminar fracture toughness is investigated experimentally and replicated numerically. The modified Transverse Crack Tensile specimen recently proposed by the authors is used, together with an experimental device designed to apply a constant transverse compressive stress on the surface of the specimen. Experiments are conducted using IM7/8552 specimens for different compressive stresses, ranging from 0 to 100 MPa, covering all the practical applications commonly encountered in the aeronautical industry (e.g., tightened filled holes or bolted joints). It is shown that mode II interlaminar fracture toughness increases …
Fronteras por definir, descontento creciente, alianzas inestables y amenazas externas: la Unión Europea y su tormenta perfecta
2018
espanolLa Union Europea se halla en una crisis existencial tan evidente que incluso politicos y analistas con antecedentes ideologicos diametralmente opues-tos han acabado coincidiendo en su diagnostico, y en la necesidad urgente de una terapia de choque que detenga lo que parece una carrera hacia la destruccion del proyecto europeo. El proposito del presente ensayo es pasar revista —aun al precio de tener que ser extraordinariamente sintetico en su abordaje— a los problemas que han sumido a la Union Europea en la mas grave crisis de su ya larga historia. Problemas que en todo caso son susceptibles de agruparse en cuatro grandes rubros: los que han ralentizado y hasta invertido el proceso d…
Acoustic spectral hole-burning in a two-level system ensemble
2020
AbstractMicroscopic two-level system (TLS) defects at dielectric surfaces and interfaces are among the dominant sources of loss in superconducting quantum circuits, and their properties have been extensively probed using superconducting resonators and qubits. We report on spectroscopy of TLSs coupling to the strain field in a surface acoustic wave (SAW) resonator. The narrow free spectral range of the resonator allows for two-tone spectroscopy where a strong pump is applied at one resonance, while a weak signal is used to probe a different mode. We map the spectral hole burnt by the pump tone as a function of frequency and extract parameters of the TLS ensemble. Our results suggest that det…
Enriqueciendo la investigación en humanidades digitales. Análisis de textos de claustros académicos de la Universidad de Valencia (1775-1779) con KH …
2020
[ES] La aplicación de métodos automatizados en cualquier investigación ha facilitado el trasvase de metodologías de una disciplina a otra, permitiendo realizar análisis cuantitativos a textos con estructura o semiestructurados. El objeto de este trabajo es aplicar a un dataset en lenguaje natural -castellano del siglo XVIII- métodos de análisis de la disciplina de documentación. Pretende establecer una metodología automática de análisis cuantitativo y cualitativo de textos, que permita enriquecer en el futuro las conclusiones procedentes del análisis histórico tradicional. Este estudio construye los procedimientos necesarios para poder aplicar análisis de frecuencia, extracción y clasificac…
Computational Offloading in Mobile Edge with Comprehensive and Energy Efficient Cost Function: A Deep Learning Approach
2021
In mobile edge computing (MEC), partial computational offloading can be intelligently investigated to reduce the energy consumption and service delay of user equipment (UE) by dividing a single task into different components. Some of the components execute locally on the UE while the remaining are offloaded to a mobile edge server (MES). In this paper, we investigate the partial offloading technique in MEC using a supervised deep learning approach. The proposed technique, comprehensive and energy efficient deep learning-based offloading technique (CEDOT), intelligently selects the partial offloading policy and also the size of each component of a task to reduce the service delay and energy …
The Ground State Electronic Energy of Benzene.
2020
We report on the findings of a blind challenge devoted to determining the frozen-core, full configuration interaction (FCI) ground state energy of the benzene molecule in a standard correlation-consistent basis set of double-$\zeta$ quality. As a broad international endeavour, our suite of wave function-based correlation methods collectively represents a diverse view of the high-accuracy repertoire offered by modern electronic structure theory. In our assessment, the evaluated high-level methods are all found to qualitatively agree on a final correlation energy, with most methods yielding an estimate of the FCI value around $-863$ m$E_{\text{H}}$. However, we find the root-mean-square devia…
La intimidad corporal en la filosofía de Ortega y Gasset
2015
[EN] In the face of the social crisis of intimacy for the extimacy, in neurosciences, and its reduction to privacy in legal field, this article explains the orteguian idea of the intimacy highlighting its bodily character. This notion of intimacy, rooted in body, discovers the sentimental aspect of reality (lyricism), and also overcomes thingism and subjectivism through the analysis of the mechanism of metaphor and the capacity of entering yourself. Reality of intimacy is conceived as enforceability (executive reality), and represents an alternative to idealism, objetivism of conscience and psychological introspection.
Relativism. A conceptual analysis
2010
In this paper, first, I will try to give a conceptual definition of relativism, with the aim of singling out the basic elements common to the most relevant relativist conceptions. I will qualify as “relativistic” all conceptions in which all or a relevant part of its criteria and beliefs necessarily depend on a given context. Secondly, I will deal with some critical observations against relativism. From this point of view, a problem arises from the fact that many relativists would like to have the chance ofexpressing some objective judgments. Lastly, I will propose a relativistic conception: one that doesn’t incorporate absolutist elements at all and nevertheless could be able to explain th…
The reception of Marx's thought in the young Habermas
2018
RESUMEN Se analiza la influencia del pensamiento de Marx en la formulación temprana de la teoría habermasiana. Para ello, se parte de las críticas de Albrecht Wellmer y Jürgen Habermas a la autocomprensión marxiana del materialismo histórico. Luego se estudia la reconstrucción de algunos postulados del marxismo llevada a cabo por Habermas en términos de una renovada teoría de la evolución social. Con ello salen a la luz algunos supuestos básicos de la teoría de Marx que aparecen trasformados en la conceptualización de Habermas y que constituyen una base ineludible para comprender el posterior pensamiento de este autor. ABSTRACT The article analyzes the influence of Marx's thought on the for…
A relevância ética da contemplação estética
2012
Schopenhauer organized his philosophy of the world as will and representationsystematically, dividing the work into four sections. The unity of the essence of the worldarises in different ways, according to the four books of the main work, by means of ournatural volitional and purposive cognition (book 1), the recognition of the “objectity” of thewill, experienced on the own body (book 2), the possibility of ideal cognition, freed fromthe will, in aesthetic contemplation (book 3) up to the understanding (“Durchschauung”)of the principium individuationis: the self-knowledge of the will (book 4). In this article,the theory of aesthetic contemplation is regarded as a philosophy of consciousnes…
