As steady progress is being made in the miniaturization of the chip features, embedded systems are quickly evolving towards complex devices, including a large set of computation engines, dedicated accelerators, input/output controllers and multiple memory buffers.
In June of 1948, the Bell Telephone Laboratories announced and demonstrated publicly a semiconductor amplifier invented by Bardeen and Brattain, and coined for it the name “transistor”, a contraction of transfer-resistor. That transistor was a point-contact transistor that consisted of…
GENERATION AND PROPAGATION OF VIBRATIONS ON SATELLITE STRUCTURES AND PLANETARY BODIES AFTER HYPERVELOCITY IMPACTS
Hyper-Velocity-Impacts (HVI) are a common problem in the space environment. They especially concern space missions, in terms of: • Potential damage to spacecrafts and satellites • Collisional evolution of small and large bodies of the Solar System This thesis focuses…
Al giorno d’oggi l’informazione e’ una delle risorse piu’ importanti per ogni tipo di organizzazione, in particolare aziende e istituzioni. E’ fondamentale per lo svolgimento di qualsiasi attivita’ che il patrimonio informativo sia disponibile prontamente e in maniera continuativa.
In this thesis we address the problem of building a model in support of maintenance optimization of a generic component of an industrial power plant, when the only available information is that elicited from an expert. In particular, we introduce…
ORGANIC THIN-FILM TRANSISTORS: AN INVESTIGATION OF DEVICE PROPERTIES, APPLICATIONS AND MARKET PERSPECTIVES
UNIVERSITA DEGLI STUDI DI CAGLIARI FACOLTA DI INGEGNERIA. Tesi per il conseguimento del Dottorato di Ricerca in Ingegneria Elettronica ed Informatica
A Semantic Web architecture, capable of indexing raw data basing on ad-hoc built ontologies and retrieving it via conceptual queries, has already been proposed (and partially developed) in its core functionalities. My aim is to attempt at proposing a viable…
