[EN] Between October 2011 and March 2012 submarine volcanic eruptions took place at El Hierro (Canary Islands). The event produced plumes of discolored waters due to the discharge of volcanic matter, gases and fluids. Field samples of Chl-a and sulphur reduced species were collected by some oceanographic cruises (Instituto Español de Oceanografía, IEO).

[EN] In this paper, we have used Geographical Information Systems (GIS) to solve the planar Huff problem considering different demand distributions and forbidden regions. Most of the papers connected with the competitive location problems consider that the demand is aggregated in a finite set of points. In other few cases, the models suppose that the demand is distributed along the feasible region according to a functional form, mainly a uniform distribution. In this case, in addition to the discrete and uniform demand distributions we have considered that the demand is represented by a population surface model, that is, a raster map where each pixel has associated a value corresponding to the population living in the area that it covers...

[ES] El reto de conseguir una red eléctrica más eficiente pasa por la introducción masiva de energías renovables en la red eléctrica, disminuyendo así las emisiones de CO2. Por ello, se propone no sólo controlar la producción, como se ha hecho hasta ahora, sino que también se propone controlar la demanda. Por ello, en esta investigación se evalúa el uso de la Ingeniería Dirigida por Modelos para gestionar la complejidad en el modelado de redes eléctricas, la Inteligencia de Negocio para analizar la gran cantidad de datos de simulaciones y la Inteligencia Colectiva para optimizar el reparto de energía entre los millones de dispositivos que se encuentran en el lado de la demanda.

[ES]La importancia sociológica de la población anciana ha crecido de manera significativa, debido a la elevada prevalencia de patologías crónicas. De entre ellas, cabe destacar el Deterioro Cognitivo Leve, la Enfermedad de Alzheimer y otras demencias corticales. Este PFC presenta una solución global, innovadora y web, con fuerte fundamento de Historia Clínica Electrónica, capaz de integrar sistemas inteligentes de ayuda al diagnóstico (SIAD) y herramientas computacionales inteligentes (HCI). Este entorno está específicamente diseñado para guiar y asistir al facultativo en la observación y la valoración del paciente afectado por estas neuropatologías. Gracias a su interoperabilidad con los SIAD y HCI, basados en computación neuronal y fusión de datos, el sistema desarrollado puede considerarse una Estación Clínica inteligente.

[EN]A new algorithm for evaluating the top event probability of large fault trees (FTs) is presented. This algorithm does not require any previous qualitative analysis of the FT. Indeed, its efficiency is independent of the FT logic, and it only depends on the number n of basic system components and on their failure probabilities. Our method provides exact lower and upper bounds on the top event probability by using new properties of the intrinsic order relation between binary strings. The intrinsic order enables one to select binary n-tuples with large occurrence probabilities without necessity to evaluate them. This drastically reduces the complexity of the problem from exponential (2n binary n-tuples) to linear (n Boolean variables)...

[EN]The continuous evolution of materials and technologies of Additive Manufacturing (AM) has led to a competitive production process even for functional parts. The capabilities of these technologies for manufacturing complex geometries allow the definition of new designs that cannot be obtained with any other manufacturing processes. An application where this capability can be exploited is the lightening of parts using internal structures. This allows to obtain more efficient parts and, at the same time, reduce the costs of material and manufacturing time. A new lightweight optimization method to optimize the design of these structures and minimize weight while keeping the minimal mechanical properties is presented in this paper.

L’obiettivo principale del lavoro è quello di effettuare un’analisi delle maggiori influenze che la lingua catalana e la lingua spagnola ebbero sulla lingua sarda durante il lungo processo di dominazione spagnola in Sardegna che durò quasi quattro secoli: dal 1323 al 1714. Dopo una breve introduzione sui principali avvenimenti storici che ebbero luogo in Sardegna e in Spagna prima dell’inizio della dominazione, si cerca di analizzare in maniera più approfondita il processo di colonizzazione da parte del popolo aragonese e del popolo spagnolo in territorio sardo. Il contatto fra i due popoli, inizialmente basato su motivi storici e politici, si è trasformato con il passare degli anni e dei secoli in un contatto fra storie, culture, tradizioni e lingue. Continuando con una breve descrizione delle tre lingue si arriva al nucleo centrale del lavoro: la lingua catalana e la lingua spagnola influiscono sulla lingua sarda apportando numerosi cambiamenti soprattutto sul piano lessicale dando così origine alla lingua che attualmente si parla in Sardegna.
