Agrigento: dai conflitti alle speranze per lo sviluppo della disciplina urbanistica

2009

La frana di agrigento ha condizionato non solo lo sviluppo di una città del sud resa nota dalla Valle dei Templi in tutto il mondo, ma ha rappresentato il momento di avvio dell'urbanistica razionale da parte dello Stato italiano. Gli esiti di quegli interventi per la città sono stati incerti ed in alcuni casi fallimentari. Solo in tempi recenti è finalmente possibile intravedere i segni del rinnovamento nella pratica urbanistica in Sicilia.

Decoupled control scheme of grid-connected split-source inverters

2017

Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…

Vers un environnement informatisé d'évaluation de la qualité ergonomique d'interfaces multimédia : Étude exploratoire

2000

Our objective is to encourage the human-computer interface designers to be more interested in the uses made of their product by taking into account to a higher degree the human-factor in the testing phase which often is too focused on technical aspects. We want to facilitate the integration of the user as a source of evaluation during the testing phase. Our aim is to offer the designer a software environment of practical tests that allow them to have their own products evaluated by their users. We undertook an experiment to explore the feasibility of this project.
