Metodi per l'analisi di accessibilità con applicazione al trasporto aereo
(Universita degli studi di Salerno, 2013-04-05)Il presente lavoro di dottorato di ricerca consiste nello studio approfondito di indicatori di accessibilità finalizzati alla valutazione quantitativa di competitività di un territorio in generale o più nel dettaglio di ... -
Sliding mode control of DC/DC switching converters for photovoltaic applications
(Universita degli studi di Salerno, 2013-03-15)The maximum power point tracking (MPPT) is one of the most important features of a system that process the energy produced by a photovoltaic generator must hold. It is necessary, in fact, to design a controller that is ... -
Development of solid oxide fuel cell stack models for monitoring, diagnosis and control applications
(Universita degli studi di Salerno, 2013-07-26)In the present thesis different SOFC stack models have been presented. The results shown were obtained in the general framework of the GENIUS project (GEneric diagNosis Instrument for SOFC systems), funded by the European ... -
Efficient indexing and retrieval from large moving object databases through dynamic spatio-temporal queries
(Universita degli studi di Salerno, 2012-10-25)Intelligent Transportatin Systems have gained a great importance in the last decades given the growing need for security in many public environments, with particular attention for traffic scenarios, which are daily interested ... -
Text retrieval and categorization through a weighted word pairs approach
(Universita degli studi di Salerno, 2013-03-19)The focus of this dissertation is the development and validation of a novel method for supervised text classification to be used effectively when small sized training sets are available. The proposed approach, which relies ... -
