Il rilevamento georeferenziato di caratteristiche fisico-meccaniche del terreno
2009
Lo scopo del presente lavoro è di eseguire il rilevamento georeferenziato di caratteristiche fisico-meccaniche del terreno (resistenza alla penetrazione, indice del relativo stato di compattamento, e sforzo di taglio normale al piano di campagna, richiesto per lavorare il terreno mediante l’utilizzo di un ripuntatore) in un appezzamento della Sicilia interna, lungo traiettorie parallele a quelle già percorse da un sistema trattore - aratro durante l’aratura eseguita cinque anni prima delle prove stesse. Il sistema di rilevamento della resistenza alla penetrazione è costituito da una cella di carico, collegata ad un’asta di penetrazione, che termina con il relativo cono ed è installata su un…
La competenza docimologica per la valorizzazione dei talenti. Una ricerca con i futuri docenti di scuola primaria e dell’infanzia
2018
Educating gifted students must be a priority for educators and education systems if society is to capitalise on their potential to contribute to an economical and sustain- able future. Given the importance of teachers in supporting academic achievement, educating preservice teachers on how to cater for gifted students commences the process as they can foster the implementation of current teaching practices that draw on sub- stantial research into the education of gifted children. If Evaluation process becomes an instrument for the development of talent in the classroom pre-service teacher training in docimological skill is necessary. In the ed- ucational field, talent and excellence find th…
An integrated methodological approach for optimising complex systems subjected to predictive maintenance
2021
Abstract The present paper addresses the relevant topic of maintenance management, widely recognised as a fundamental issue involving complex engineering systems and leading companies towards the optimisation of their assets while pursuing cost efficiency. With this regard, our research aims to provide companies with a hybrid methodological approach based on Multi-Criteria Decision-Making (MCDM) capable to deal with the main failures potentially involving complex systems subjected to predictive maintenance. Such an approach is going to be integrated within the framework of traditional Failure Mode Effects and Criticality Analysis (FMECA), whose strengths and weaknesses are considered. In pa…

Eleccions al Congrés dels Diputats, Parlament de Catalunya, Corts Valencianes i Parlament Balear (1977-1991)
1992
ESTE ARTICULO INTENTA EXPLICAR EL COMPORTAMIENTO ELECTORAL EN LOS PAISES CATALANES COMPARANDO EL RESULTADO DE LAS ELECCIONES AL CONGRESO DE LOS DIPUTADOS Y A LOS PARLAMENTOS CATALAN, VALENCIANO Y BALEAR ENTRE 1977 Y 1991. SE HA UTILIZADO PARA ELLO LOS DATOS DE LOS ANUARIOS DE EL PAIS HASTA LAS ELECCIONES DE 1988 Y LOS DIARIOS OFICIALES DE LA GENERALITAT VALENCIANA Y DEL GOBIERNO BALEAR PARA LAS ELECCIONES AUTONOMICAS DE 1991. LA GEOGRAFIA ELECTORAL SE HA CONVERTIDO EN UN CAPITULO IMPORTANTE DENTRO DE LA GEOGRAFIA POLITICA COMO DEMUESTRAN, ENTRE OTROS, TAYLOR Y JOHNSTON -A NIVEL INTERNACIONAL- Y LOS TRABAJOS DE SENDRA Y DE JOSEP MARª VALLES -A NIVEL ESPAÑOL.

Tamaño del distrito y voto estratégico en España
2004
En este estudio se analizan los efectos psicológicos del sistema electoral, prestándose atención a la influencia del tamaño o magnitud del distrito electoral en la utilización estratégica del voto en las elecciones del Congreso de los Diputados. Para medir la incidencia del voto estratégico en el comportamiento de los votantes españoles entre 1982 y 2000 se aplican los diversos enfoques propuestos para estudiar este fenómeno. Los resultados permiten afirmar que la variable institucional constituida por el sistema electoral ?el tamaño o la dimensión del distrito, o sea, la diferencia entre distritos grandes y pequeños? influye en el comportamiento de los electores.

Numerical and Experimental Analysis of the Frictional Effects on 4ENF Delamination Tests Performed on Unidirectional CFRP
2015
Abstract Progressive delamination in composite materials under static or fatigue loading condition are, in many structures, one of the predominant cause of failure. In the paper, an accurate study of quasi-static delamination growth under mode II loading condition is conducted. Several experimental tests are performed on composite laminates consisting of unidirectional carbon/epoxy layers. Four-point end-notched flexure (4ENF) test is employed in order to characterize the mode II interlaminar fracture toughness. The R-curve is obtained by means of optical and numerical determination of crack tip position. The energy release rate and the crack length are calculated through experimental deter…
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 …
Elecciones primarias en España. 1993-2015
2015
“Elecciones primarias en España. 1993-2015 ” analiza la intro¬ducción y desarrollo de las elecciones primarias de los partidos políti¬cos en España, y como una forma de participación típica de la política de los EE.UU., va consiguiendo arraigar en los partidos españoles. Será el PSOE el primero que implante el sistema de primarias (Con¬ferencia Política del PSPV en 1993); después en las elecciones pri¬marias para elegir candidato a la Presidencia del Gobierno de España (Almunia-Borrell), por elección directa entre todos los afiliados socia¬listas (1998); y a través de primarias abiertas a simpatizantes en la elección del candidato socialista a la Presidencia de la Generalitat Valenciana (20…
