Bibliometrics applied to gamification as a digital learning strategy
2019
Este trabajo se interesa por un tema de actualidad como es la gamificación en educación, una interesante estrategia didáctica para responder a los alarmantes datos sobre fracaso y abandono escolar obtenidos año tras año en las pruebas diagnósticas realizadas en el ámbito europeo. A través del estudio bibliométrico de la producción científica se ha analizado las principales tendencias en gamificación, como práctica mediada por la tecnología en las aulas de las diferentes etapas educativas, a través de 137 documentos alojados en la base de datos Scopus y publicados en la última década. En los resultados se revela que el número de documentos se ha incrementado notablemente en los últimos años;…
Factory Workers' Ordinary User Experiences: An Overlooked Perspective
2018
Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …
A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
A Nonlinear Control of Synchronous Reluctance Motors (SynRM) Based on Feedback Linearization Considering the Self and Cross-Saturation Effects
2019
This paper proposes a nonlinear controller based on feedback linearization for Synchronous Reluctance Motors (SynRM) drives that takes into consideration the self and cross-saturation effects. Such control technique permits the dynamics of both the speed and flux loops to be maintained constant independently from the load and the saturation of the iron core. The proposed technique has been tested experimentally on a suitably developed test set-up.
Flipped Classroom e sviluppo delle soft skills nella formazione iniziale dei futuri insegnanti
2019
La presente ricerca empirica si sviluppa in continuità con gli studi avviati, fin dal 2014, per elaborare setting didattici, atti a favorire il successo acca-demico di studenti che si preparano a divenire insegnanti. Nell’ambito dell’attuale studio sono stati elaborati percorsi didattici mirati centrati sullo sviluppo delle soft skills. Le soft skills come la comunicazione, la collaborazione, la creatività e l'im-prenditorialità sono sempre più richieste in campo educativo. Come possiamo misurare queste competenze relazionali e gestionali? Come gli studenti (futu-ri insegnanti) possono dimostrare di possederle? Come queste soft skills ven-gono agite negli ambienti digitali? Nel tentativo di…
Equilibrium fluid-crystal interfacial free energy of bcc-crystallizing aqueous suspensions of polydisperse charged spheres
2015
The interfacial free energy is a central quantity in crystallization from the meta-stable melt. In suspensions of charged colloidal spheres, nucleation and growth kinetics can be accurately measured from optical experiments. In previous work, from this data effective non-equilibrium values for the interfacial free energy between the emerging bcc-nuclei and the adjacent melt in dependence on the chemical potential difference between melt phase and crystal phase were derived using classical nucleation theory. A strictly linear increase of the interfacial free energy was observed as a function of increased meta-stability. Here, we further analyze this data for five aqueous suspensions of charg…
Mechanics of invagination and folding: Hybridized instabilities when one soft tissue grows on another
2015
We address the folding induced by differential growth in soft layered solids via an elementary model that consists of a soft growing neo-Hookean elastic layer adhered to a deep elastic substrate. As the layer/substrate modulus ratio is varied from above unity towards zero we find a first transition from supercritical smooth folding followed by cusping of the valleys to direct subcritical cusped folding, then another to supercritical cusped folding. Beyond threshold the high amplitude fold spacing converges to about four layer thicknesses for many modulus ratios. In three dimensions the instability gives rise to a wide variety of morphologies, including almost degenerate zigzag and triple-ju…
Fostering learning and innovation skills in Initial Teacher Education
2018
L'opportunità di partecipare attivamente alla formazione iniziale degli insegnanti e l'esperienza di ricerca svolta durante il dottorato ha consentito all’a. di verificare come creare, attraverso l’uso delle tecnologie, ambienti di apprendimento e situazioni didattiche che migliorano le soft skills dei futuri docenti. È stato così possibile esplorare nuovi ambienti di apprendimento e di insegnamento, nuove forme organizzative e nuove modalità di interazione tra docenti e studenti verificandone la validità e l’efficacia. Le conclusioni ricavate dalla ricerca hanno fornito indicazioni utili per il miglioramento delle competenze trasversali dei futuri docenti. Numerous studies reveal that ther…
A Performance Evaluation of Fusion Techniques for Spatio-Temporal Saliency Detection in Dynamic Scenes
2013
International audience; Visual saliency is an important research topic in computer vision applications, which helps to focus on regions of interest instead of processing the whole image. Detecting visual saliency in still images has been widely addressed in literature. However, visual saliency detection in videos is more complicated due to additional temporal information. A spatio-temporal saliency map is usually obtained by the fusion of a static saliency map and a dynamic saliency map. The way both maps are fused plays a critical role in the accuracy of the spatio-temporal saliency map. In this paper, we evaluate the performances of different fusion techniques on a large and diverse datas…
