Abstract:Outdoor lighting is an essential service for modern life. However, the high influence of this type of facility on energy consumption makes it necessary to take extra care in the design phase. Therefore, this manuscript describes an algorithm to help light designers to get, in an easy way, the best configuration parameters and to improve energy efficiency, while ensuring a minimum level of overall uniformity. To make this possible, we used a particle swarm optimization (PSO) algorithm. These algorithms are well established, and are simple and effective to solve optimization problems. To take into account the most influential parameters on lighting and energy efficiency, 500 simulations were performed using DIALux software (4.10.0.2, DIAL, Ludenscheid, Germany). Next, the relation between these parameters was studied using to data mining software. Subsequently, we conducted two experiments for setting parameters that enabled the best configuration algorithm in order to improve efficiency in the proposed process optimization.

Resumen-La formación a la largo de la vida es necesaria en cualquier institución o empresa. La autoformación mediante minivídeos es una opción ágil y efectiva. Sin embargo, la elaboración de estos materiales digitales supone un costo en recursos, tiempo, esfuerzo y dinero que puede ser inasumible. Asimismo, estos recursos multimedia suelen incumplir la Directiva Europea de Accesibilidad Digital. En este trabajo se presenta una metodología para la elaboración de mini-vídeos formativos de bajo coste, accesibles y multilingües. Entendiendo como mini-videos a aquellos que tienen una duración de entre 5 y 10 minutos aproximadamente. De igual modo, se presenta un proyecto en desarrollo en el que se aplicará dicha metodología en la formación que realiza la Biblioteca de la Universidad de Jaén. Esta praxis permitirá refinar la metodología, evaluar su eficacia en función del coste, y en su caso, proponer un proceso sistemático de elaboración de mini-vídeos que se pueda integrar fácilmente en la gobernanza de Tecnología de la Información (TI) de cualquier institución, organismo o empresa.Palabras clave: Educación Universitaria, Aprendizaje a lo largo de la vida, recursos multimedia accesibles, elearning modular, minivídeos, accesibilidad, multilingüismo Abstract-Lifelong learning is necessary at any institution or company. Self-training using mini-videos is an agile and effective option. However, the development of digital material needs resources: time, effort and money that could be unaffordable. In addition, these multimedia resources usually fail to comply the European Directive on Digital Accessibility. This paper presents a methodology for the development of low cost and accessible training mini-videos with multilingual support. It is understood that a minivideo is a video whose duration is approximately 5-10 minutes. Also, it presents the project in which this methodology and techniques are being applied for the training carried out by the Service of Library at the University of Jaén. This proposal will allow to refine and assess effectiveness and cost of current training. Finally, the proposal aims to define a systematic process of developing mini-videos that can be easily integrated into the Information Technology (IT) governance of any institution, organization or company.
