Gestor de radio FM y sistema RDS - FM radio RDS

En este documento se recoge toda la documentación asociada al desarrollo de la aplicación para dispositivos móviles Firefox OS, FM Radio RDS. La experiencia ha sido muy satisfactoria, a pesar de las frustraciones pasadas. Se han conseguido cumplir todos los objetivos establecidos inicialmente, obteniendo como resultado una aplicación muy cercana a la ideada. Se puede considerar una herramienta útil y novedosa para la reproducción de la radio FM en función de la posición en los dispositivos con el sistema operativo móvil Firefox OS. Se tiene previsto añadir futuras mejoras, como darle un enfoque más social. Personalmente, se han logrado alcanzar habilidades en el desarrollo de aplicaciones web que me permitirán realizar otros proyectos futuros. A pesar de no haber cumplido con los plazos establecidos en la planificación principal, la sensación personal es positiva al haber conseguido realizar un trabajo de tal magnitud por cuenta propia.

Holding mirrors up to Hamlet: what Franco Zeffirellis and Michael Almereydas filmic adaptations of the play tell us about it

Hamlet (1601), de William Shakespeare, é, desde o Fólio de 1623, circundada por um enorme e variado volume de leituras, que abrangem desde textos críticos e teóricos até as mais diversas adaptações teatrais e cinematográficas. Desde o final do século 19, o cinema vem adaptando peças de Shakespeare, fornecendo novos pontos de vista e sugestões para a encenação dessa obra ao levá-la inúmeras vezes para as telas. Dentre uma longa lista de adaptações fílmicas de Hamlet, o Hamlet mainstream de Franco Zeffirelli (1990) e o Hamlet 2000 (2000), filme independente de Michael Almereyda, compõem o corpus eleito para análise nesta dissertação. Dialogando com noções de críticos e teóricos que desenvolveram estudos sobre o conceito de adaptação, tais como André Bazin, Robert Stam e Linda Hutcheon, sugiro uma desierarquização entre a peça shakespeariana e os filmes logo, entre literatura/teatro e cinema. O objetivo final deste trabalho encontra-se na proposta de uma reflexão sobre esses filmes enquanto potenciais materiais críticos elucidativos para o estudo da peça, úteis na discussão de alguns de seus mais importantes temas e/ou questões

A Novel Micro- and Nano-Scale Positioning Sensor Based on Radio Frequency Resonant Cavities

In many micro- and nano-scale technological applications high sensitivity displacement sensors are needed, especially in ultraprecision metrology and manufacturing. In this work a new way of sensing displacement based on radio frequency resonant cavities is presented and experimentally demonstrated using a first laboratory prototype. The principle of operation of the new transducer is summarized and tested. Furthermore, an electronic interface that can be used together with the displacement transducer is designed and proved. It has been experimentally demonstrated that very high and linear sensitivity characteristic curves, in the range of some kHz/nm; are easily obtainable using this kind of transducer when it is combined with a laboratory network analyzer. In order to replace a network analyzer and provide a more affordable, self-contained, compact solution, an electronic interface has been designed, preserving as much as possible the excellent performance of the transducer, and turning it into a true standalone positioning sensor. The results obtained using the transducer together with a first prototype of the electronic interface built with cheap discrete elements show that positioning accuracies in the micrometer range are obtainable using this cost-effective solution. Better accuracies would also be attainable but using more involved and costly electronics interfaces.

Low temperature growth of c-axis oriented AlN films on gamma-LiAlO2 by radio frequency magnetron sputtering

Aluminum nitride (AlN) films were prepared on gamma-LiAlO2 substrates by radio frequency (rf) magnetron sputtering. The influence of substrate temperature (T-s) and nitrogen (N-2) concentration on film growth was investigated. The X-ray diffraction (XRD) results reveal that highly c-axis oriented AlN films can be obtained in the temperature range from room temperature (RT) to 300 degrees C. A smoother surface and a crystalline quality decrease with increasing N-2 concentration have been observed by XRD and atomic force microscopy (AFM) for the films deposited at lower substrate temperature. On the contrary, the degradation of the surface smoothness and the higher crystalline quality can be observed for the films deposited at a higher substrate temperature with N-2-rich ambient. The growth mechanism which leads to different crystalline quality of the films is discussed. (C) 2008 Elsevier B.V. All rights reserved.

The use of role-play games in teaching: The International Climate Negotiation Game

This paper presents a role-play game designed by the authors, which focuses on international climate negotiations. The game has been used at a university with students all drawn from the same course and at summer schools with students from different levels (undergraduate, master’s and doctoral students and post-doctoral researchers) and different knowledge areas (economics, law, engineering, architecture, biology and others). We discuss how the game fits into the process of competence-based learning, and what benefits games, and role-play games in particular, have for teaching. In the game, students take on the role of representatives of national institutions and experience at first hand a detailed process of international negotiation concerned with climate change.

ADAPTECC: A Role-Play Game about Adapting to Climate Change

The ADAPTECC Climate Change Adaptation Game is a role-play game designed to enable players to experience the difficulties that arise at local and regional levels when authorities have to implement adaptation measures. Adaptation means anticipating the advert effects of climate change (CC) and taking measures to prevent and minimise the damage caused by its impacts. Each player takes the role of the mayor or a councillor of a town affected by CC who must decide what adaptation strategies and measures to take, or of a member of the Regional Environment Department which must distribute funding for adaptation among the various towns. At the end of the game, players should have a greater understanding of the challenges posed by adaptation to CC
