This paper describes a representation of the legal framework in the air transport passenger's rights domain and the foremost incidents that trigger the top of consumer complaints ranking in the EU. It comprises the development of a small network of three ontologies, formalisation of scenarios, specification of properties and identification of relations. The approach is illustrated by means of a case study based in the context of a real life cancelled flight incident. This is part of an intended support-system that aims to provide both consumers and companies with relevant legal information to enhance the decision-making process.

This paper aims to present a preliminary version of asupport-system in the air transport passenger domain. This system relies upon an underlying on-tological structure representing a normative framework to facilitatethe provision of contextualized relevant legal information.This information includes the pas-senger's rights and itenhances self-litigation and the decision-making process of passengers.Our contribution is based in the attempt of rendering a user-centric-legal informationgroundedon case-scenarios of the most pronounced incidents related to the consumer complaints in the EU.A number ofadvantages with re-spect to the current state-of-the-art services are discussed and a case study illu-strates a possible technological application.

Durante el siglo XX, hemos pasado de ser una sociedad activa que disfrutaba de la ciudad a medida que recorría sus calles, a ser una sociedad motorizada cuyo interés principal es transportarse de un punto A a un punto B en el menor tiempo posible. En este siglo XXI, la concepción del espacio urbano y de la vida cotidiana se encuentra en un movimiento de rechazo de esta ideología anterior. Ya no nos interesan esas ciudades funcionales diseñadas solamente para los vehículos y un movimiento de recuperación del espacio urbano se ha iniciado sobre una trama de ciudad todavía anclada en el pasado. Este ensayo pretende analizar los retos provenientes de este cambio ideológico y dar una serie de soluciones a la conversión de espacios públicos de tránsito en espacios de estar al aire libre que den pie a una sinergia comunicativa de sus gentes. Hoy en día nos encontramos con los inicios de este movimiento de cambio que busca una mejora en la salud y la vida cotidiana de los ciudadanos, previamente relegados a espacios libres públicos muy acotados. Ahora, todo el espacio libre se convierte en espacio para sus ciudadanos buscando crear de esta forma una “sala de estar” al aire libre.

In electric vehicles, passengers sit very close to an electric system of significant power. The high currents achieved in these vehicles mean that the passengers could be exposed to significant magnetic fields. One of the electric devices present in the power train are the batteries. In this paper, a methodology to evaluate the magnetic field created by these batteries is presented. First, the magnetic field generated by a single battery is analyzed using finite elements simulations. Results are compared to laboratory measurements, taken from a real battery, in order to validate the model. After this, the magnetic field created by a complete battery pack is estimated and results are discussed.
