We propose an infrastructure where it is possible to work with physical, virtual and mixed laboratories</span>
Internet y contrato de juego: el juego on line y la regulación del contrato de juego y apuesta en el derecho español.
2015
El juego y la apuesta siempre han tenido interés para el Derecho y, particularmente, para el Derecho Civil. Los Códigos civiles han regulado el contrato de juego y apuesta atendiendo a la realidad de la época de la codificación. Internet ha supuesto una auténtica revolución en muchas materias del Derecho Civil y muy especialmente, en la concepción y práctica del juego y la apuesta. El juego y apuesta on line ha hecho necesaria una nueva regulación jurídica conforme a la realidad actual. La mencionada regulación tiene un importante componente privado, como es el contrato de juego y apuesta. El presente trabajo aborda el impacto de internet en los juegos y apuestas, el juego on line y la regu…
Personality Variables as Predictors of Facebook Usage
2014
This study investigates the role of personality factors as predictors of Facebook usage. Data concerning Facebook usage and personality factors from 654 Facebook users were gathered using a web survey. Using path analysis, the results showed Openness was a predictor of Facebook early adoption, Conscientiousness with sparing use, Extraversion with long sessions and abundant friendships, and Neuroticism with high frequency of sessions. The possible role of Agreeableness in predicting low session frequency and friendships needs further validation.
AN EXTENDED KALMAN FILTER BASED TECHNIQUE FOR ON-LINE IDENTIFICATION OF UAS PARAMETERS.
2015
The present article deals with the identification,at the same time, of aircraft stability and control parameters taking into account dynamic damping derivatives. Such derivatives,due to the rate of change of the angle of attack, are usually neglected. So the damping characteristics of aircraft dynamics are attributed only on pitch rate derivatives. To cope with the dynamic effects of these derivatives, authors developed devoted procedures to estimate them. In the present paper, a complete model of aerodynamic coefficients has been tuned-up to identify simultaneously the whole set of derivatives. Besides, in spite of the employed reduced order model and/or decoupled dynamics, a six degrees o…
An Extended Kalman Filter-Based Technique for On-Line Identification of Unmanned Aerial System Parameters

Experiencia sobre la utilización de un mix de metodologías docentes en la educación universitaria de la contabilidad
2012
En este trabajo se analiza la introducción de nuevas metodologías docentes a título experimental en un curso de contabilidad financiera. Las nuevas técnicas empleadas en clase han sido de varios tipos: mapas conceptuales, crucigramas, técnica del "puzzle" o aprendizaje cooperativo y test on-line, entre otras. Concretamente, se analiza la mejora en el rendimiento de los estudiantes mediante la comparación con resultados de otros años. Así mismo, se estudia el grado de satisfacción de los estudiantes con las nuevas herramientas docentes empleadas. Se analiza si mejora el nivel de motivación por una mayor comprensión de los contenidos, por un mayor número de horas de estudio a lo largo del per…
Production of neutron deficient rare isotope beams at IGISOL; on-line and off-line studies
2004
This article reports on recent on-line yield measurements employing the light-ion and heavy-ion reaction-based ion guide systems and new results on a-recoil ion transport properties in ion guides with and without electric fields. In addition, the presently used ion guide designs for fusion evaporation reactions are introduced. The present study investigated different schemes for ion extraction from the gas cell. The addition of an extra ring electrode between the traditional skimmer electrode and the exit hole led to transmission independent of the primary beam intensity as opposed to strong intensity dependence observed earlier with the plain skimmer only. Furthermore, the mass resolving p…
Empleo de Socrative para la evaluación del trabajo previo en asignaturas prácticas de laboratorio
2019
[EN] University students of experimental sciences degrees usually go to the laboratory of practices without having prepared the corresponding activity. This fact leads to a poor preparation of them translated into an effective loss of time available for experimentation, and a reduced acquisition of knowledge and skills, among other aspects. In order to solve this problem, in the present communication, the use of on-line questionnaires using the Socrative platform is described to be used as a prior evaluation system to access the laboratory. The results obtained show that the proposed didactic strategy significantly improves the preparation of the students upon arrival to the laboratory, as …
On-line assessment of comprehension processes
2009
In this paper we describe a new version of a former paper-and-pencil standardized comprehension test called Test of Comprehension Processes (Vidal-Abarca, Gilabert, Martínez, & Sellés, 2007). The new version has been adapted to a computer-based environment based on the moving window technique. It can be used to assess comprehension strategies of students from fifth to tenth grades (11 to 16 years old). Comprehension strategies are registered on-line using reading times and visits to relevant sections of the text during the question-answering process. Data show that the computerbased version draws similar results to those provided by the paper-and-pencil version. In addition, we identify the…
The development and status of the IGISOL technique
1997
Abstract The development of the IGISOL technique since its earliest beginnings at the University of Jyvaskyla in the early '80s is reviewed. The processes involved in ion survival in the ion guide are discussed. The design and performance of ion guides for different types of reactions is summarised. The mass-separated beam quality for different skimmer systems is compared.
