Comprensió de la lectura en alumnes d'ensenyament secundari
2006
Aquest treball es planteja per conèixer més de primera mà la comprensió i assimilació de textos escrits, en alumnes de l'actual ensenyament secundari. La mostra emprada va ser de 28 alumnes entre 14 i 20 anys, de 3r d'ESO i COU majoritàriament, de l'Institut d'Ensenyament Secundari «Alameda de Osuna» de Madrid. Els resultats obtinguts en aquest estudi indiquen que, en els lectors de menor edat els processos de lectura són més simples i en alguns casos incomplets, mentre que els lectors de major edat fan una lectura que implica processos cognitius més complexos, adequats i profunds.

Numerical and experimental analysis of a high innovative hydrofoil
2020
The hydrofoil is a craft where the weight is entirely supported by the lift generated by the submerged part of wings. The particular structure of the craft requires a thorough study of the architecture of the hull, whose structure differs from others high speed vessels since the lift on wing surfaces are transmitted to the hull in limited areas (wing attacks). The authors have developed a research to optimize geometry of hull and wing system on a hydrofoil capable to carry 250 passengers at a speed of 35 knots, operating among Sicilian island. The principal goals of the new hydrofoil concern both the fuel reduction that the improvement of the comfort in terms of seakeeping and levels of aco…
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…
Biomechanical analysis of two types of osseointegrated transfemoral prosthesis
2020
In the last two decades, osseointegrated prostheses have been shown to be a good alternative for lower limb amputees experiencing complications in using a traditional socket-type prosthesis
Advanced Techniques for Design and Manufacturing in Marine Engineering
2022
Modern engineering design processes are driven by the extensive use of numerical simulations, and naval architecture as well as ocean engineering are no exception. Structural design or fluid dynamic performance evaluation can only be carried out by means of several dedicated pieces of software. Classical naval design methodology can take advantage of the integration of these pieces of software, giving rise to more robust design in terms of shape, structural and hydrodynamic performances, and manufacturing processes. This Special Issue (SI) on “Advanced Techniques for Design and Manufacturing in Marine Engineering”, published in the Journal of Marine Science and Engineering, aimed to invite …
Propiedades psicométricas del Cuestionario de conciencia emocional en población infantil española
2016
La competencia emocional es la capacidad para percibir, expresar, comprender, regular y controlar nuestras emociones y las de los demás. La conciencia emocional es la competencia básica que permite el desarrollo del resto de competencias emocionales durante la infancia y la adolescencia. En este trabajo, se han estudiado las propiedades psicométricas de la versión española del Cuestionario de conciencia emocional, administrado a 1476 niños/as españoles (8-12 años). Se ha replicado la estructura original formada por seis factores. Se han estudiado la fiabilidad de los ítems y del instrumento, la validez de constructo, de contenido y concurrente, los resultados han sido satisfactorios. Se han…
Bremsstrahlung from a repulsive potential: attosecond pulse generation
2008
The collision of an electron against a repulsive potential in the presence of a laser field is investigated. It is found that a sufficiently strong laser field forces the electron to remain in the neighbourhood of the repulsive potential causing bremsstrahlung. By appropriately filtering the emitted signal, an electron in the presence of a repulsive potential is capable of generating attosecond pulses.
Three-mode two-boson Jaynes–Cummings model in trapped ions
2006
In this paper, we analyse a two-boson three-mode Jaynes–Cummings model which can be implemented in the context of trapped ions. The symmetries of the Hamiltonian are brought to light and analysed in detail in order to solve the eigenvalue problem. The calculation of the time evolution operator shows the possibility of realizing interesting applications, such as the generation of nonclassical states.
Gli approfondimenti conoscitivi e le tecniche per la conservazione delle consistenze monumentali della chiesa di Sant’Anna a Palermo
2010
Il contributo è un riassunto del progetto ed evidenzia, in particolare, gli approfondimenti conoscitivi e le tecniche per il risanamento e la manutenzione delle consistenze della chiesa, caratterizzata dalla sinuosa facciata barocca. The contribution is a graphic abstract of the project and highlights, in particular, the in-depth knowledge and techniques for the restoration and maintenance of the material consistency of the church, characterized by its sinuous baroque facade.
