Cristina; Romero Durán, David; Nejjari Akhi-Elarab, Fatiha; Álvarez del Castillo, María Dolores; Roca Lefler, Marta; Hernández Farràs, Jorge; Montferrer Liñan, Raul Abstract: This document presents the use of a self-video-recording service for the integration and assessment of certain generic competences (oral and written communication, teamwork and third (English) language) in all degree programs related to the Industrial area at the Terrassa School of Engineering (EET). The resulting service allows to carry out the assessment through active and collaborative learning methodologies using ICT as a support, becoming an educational resource where students are encouraged to evaluate their own activity, individually and in groups (co-evaluation), and with which the faculty can enhance certain sections of the syllabus while also evaluating generic competences. This paper outlines the rationale and design of the system based on self-recording-video that assists work on some generic competences. A preliminary experience has taken place and it has been carried out by volunteer students and some professors from the promoting team. It consisted of following all steps to obtain the video-recording as a result and fulfil the further assessment. Preparing the defence of the final project career, explaining the way a problem is faced are examples of use of the service endowed to assist the assessment of some generic competences. A good number of students and professors have participated in this preliminary experiment carried out on some subjects and in which oral effective communication will be assessed. A specific rubric for the assessment of generic competences has been used both for students and faculty. There is a summary of qualitative feedback from both students and instructors, and where several issues related to improving the self-assessment and self-video-recording system, are discussed. Finally, a survey is proposed, whose results will be helpful for its improvement.

A composite material constituted of poly lactide and CFs is proposed in order to prepare a biodegradable composite with low environmental impact. In order to evaluate its environmental impact, a Life Cycle Assessment (LCA) is performed. The results show that, from the environmental point of view, the more chicken feathers in the material, the greater is its impact. This is mainly due to the non - inclusion of the impact data regarding CFs current waste management treatments required in accordance with the European Directive CE 1069/2009 (in study) and to the high energy consumption of the pre - treatment stages (cleaning and sanitizing) required to transform CFs waste into a CFs technical material that can be used for the preparation of CFs/PLA composites material, which needs to be optimized.

En primer lugar, es necesario definir la física y las complejas relaciones entre todos los elementos que pertenecen al modelo. En segundo lugar, es necesario entender estas relaciones por un equipo que normalmente está compuesto por personal con experiencia y formación diferente. En este trabajo, proponemos el uso de un lenguaje formal para representar el comportamiento dinámico de un modelo que representa todo el ciclo de vida de un edificio (diseño, construcción, uso‐mantenimiento y deconstrucción), y técnicas de co‐simulación para combinar motores de simulación diferentes y obtener lo mejor de cada uno. Se presenta un modelo de sostenibilidad, Building OptiSim, de tal manera que permite obtener una solución óptima. El edificio que utilizamos para realizar la simulación es la construcción LOW 3, proyecto presentado en el concurso Solar Decathlon 2010, por la ETSAV (UPC).

Their structure (i.e., topology) and dynamics have been thoroughly studied and many topological measures have been used in order to classify them, evaluate their behavior in terms of robustness or model their dynamic response to malfunctions. Generally speaking, results have been mainly theoretical and sound correlations between real grid’s dynamical behavior (i.e., malfunctions and major events) and any of the mentioned before measures have not yet been found. In recent years, though, new extended topological measures have been used to quantify the ability of a network in sustaining its basic functions. In this paper we present a first attempt to correlate these new measures with real malfunction data for some major European power transmission grids. Similar behavior is found, in terms of robustness to selected attacks to buses, between different networks. This is measured by means of extended topological indexes electrically better defined. These behaviors can be (weakly) correlated with similar probability distributions of major events, identifying similar dynamical response among topologically similar grids. This would raise hopes in finding a more meaningful and significant linkage between structural measures and the real dynamical output (i.e., major events) of a grid.

The effect of different sanitizing methods on the properties of both CFs and the corresponding CMs has been studied. Some characteristic parameters such as density have been found to be dependent on the treatment that CFs endure, whereas the mechanical properties of the CMs made of thermoplastics matrices (e.g. polypropylene and high density polyethylene) were only slightly affected by the treatment. The introduction of CFs decreased the tensile strength of the CMs compared with the neat polymers while other parameters (e.g. Young’s modulus) were essentially unaffected Fri, 27 Jul 2012 09:35:40 GMT http://hdl.handle.net/2117/16355 2012-07-27T09:35:40Z Carrillo Navarrete, Fernando; Macanàs de Benito, Jorge; Colom Fajula, Xavier; Cañavate Ávila, Francisco Javier; Molins Durán, Gemma; Álvarez del Castillo, María Dolores; Garrido Soriano, Núria no Chicken feathers (CFs), mainly discarded nowadays, are an alternative reinforcement to be applied in the preparation of composite materials (CMs).
