Educational policies in the production and distribution of digital didactic materials

2017

En este artículo abordamos el análisis de las políticas educativas de tres comunidades autónomas (CA) tan diversas geográfca, social y culturalmente como son Canarias, Galicia y Valencia. El trabajo se enmarca en el proyecto de investigación EDU-2015-64593-R, fnanciado por el Ministerio de Economía y Competitividad, titulado: «LLa escuela de la sociedad digital: análisis y propuestas para la producción y uso de los contenidos digitales educa - tivos», en el que participan las universidades de La Laguna, Santiago de Compostela y de Valencia. El objetivo fundamental es analizar la situación de los Materiales Didácticos Digitales (MDD) en las citadas CA. En la primera fase del estudio se han e…

As-built graphic documentation of the Monumento a la Tolerancia. Validation of low-cost survey techniques

2020

[EN] The Monumento a la Tolerancia is an emblematic sculpture realized by Eduardo Chillida, a perfect example for the documentation of sculptures with uniform textures, non-reflective colours and with poorly elaborated shapes through the implementation of various photogrammetric tools, as well as using different applications for processing phase. The basic data are photos taken quickly and without an accurate previous study, which is why the implementation of any target was not foreseen. In order to prove the results different kind of analysis were conducted. The first type was carried out analysing the results obtained from different software, with the use of the same instrument. The secon…

A set of indicators for arc faults detection based on low frequency harmonic analysis

2016

In this paper a novel set of indicators is presented for arc faults detection in electrical circuits. The indicators are defined starting from an experimental characterization of the arc fault phenomenon and the study of the arcing current in several test conditions, which were chosen in accordance with the UL 1699 Standard requirements. The proposed parameters are measured by means of a high resolution low frequency spectral analysis of the arcing current, which allows to achieve a good spectral resolution even with short observation windows.

Studio delle prestazioni di giunzioni incollate ibride (Strength evaluation of structural hybrid bonded joints)

2013

The idea of “hybrid joints” arises from the need of joining together materials, producing a tough, stiff and lightweight joint. The core concept is: use two different joining techniques, with the aim to increase the strength and gather the advantages of each technique, reducing the drawbacks. In this work hybrid joints consist in joints produced with two different kinds of joining techniques: one of them being adhesive bonding and the other being one among Resistance Spot Welding, Pop Riveting, Clinching, Self Piercing Riveting. The performance of hybrid joints are compared with those of traditional joints for the single lap joint geometry, for different geometric (plates thickness, pitch o…

From Silk to Digital Technologies: A Gateway to New Opportunities for Creative Industries, Traditional Crafts and Designers. The SILKNOW Case

2020

Nowadays, cultural heritage is more than ever linked to the present. It links us to our cultural past through the conscious act of preserving and bequeathing to future generations, turning society into its custodian. The appreciation of cultural heritage happens not only because of its communicative power, but also because of its economic power, through sustainable development and the promotion of creative industries. This paper presents SILKNOW, an EU-H2002 funded project and its application to cultural heritage, as well as to creative industries and design innovation. To this end, it presents the use of image recognition tools applied to cultural heritage, through the interoperability of …

Thermal stress analysis of different full and ventilated disc brakes

2015

During the braking phase, the heat produced by friction between pads and disc cannot be entirely dissipated. Consequently, the brake disc, especially if very hard braking occur, can accumulate large amounts of heat in a short time so producing high gradients of temperature on it. Under these conditions, functionality and safety of the brake system can be compromised. The object of this study is to investigate, under extreme working conditions, the thermomechanical behaviour of different brake rotors in order to evaluate their efficiency and stability and to identify any compromising weakness on them. In particular, by means of FEM thermo-mechanical coupled analyses, one full disc and three …

Methodological frontier in operational analysis for roundabouts: a review

2016

Several studies and researches have shown that modern roundabouts are safe and effective as engineering countermeasures for traffic calming, and they are now widely used worldwide. The increasing use of roundabouts and, more recently, turbo and flower roundabouts, has induced a great variety of experiences in the field of intersection design, traffic safety, and capacity modeling. As for unsignalized intersections, which represent the starting point to extend knowledge about the operational analysis to roundabouts, the general situation in capacity estimation is still characterized by the discussion between gap acceptance models and empirical regression models. However, capacity modeling mu…
