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 ...
Planning and control of electric distribution networks with integration of wind turbines
(Universita degli studi di Salerno, 2013-03-25)
In this thesis, deterministic and probabilistic methods are developed for optimal planning of distribution networks with integration of WTs within a market environment.
With regards to the deterministic methods, hybrid ...
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 ...
Models and methods for the design of isolated power converters in high-frequency high-efficiency applications
(Universita degli studi di Salerno, 2013-03-19)
Isolated power supplies design requires the achievement of overall stress, losses, cost, size and reliability trade-off. This problem is of considerable importance in modern applications of power converters, as for energy ...
Analysis and design of 4H-SiC bipolar mode field effect power (BMFET)
(Universita degli studi di Salerno, 2013-03-20)
Analysis and design of a new Silicon Carbide polytype 4H (4H-SiC) bipolar power transistor are
the main topics of this Ph.D. thesis. The device is the Bipolar Mode Field Effect Transistor
(BMFET) and exploits the electric ...
Carbon nanotube based networks, bio-nano-composites and sensors
(Universita degli studi di Salerno, 2013-03-15)
The formation of a photosensitive device due to the local breakdown in an MOS structure with an impurity containing oxide layer has been observed. A stepwise breakdown of the oxide layer resulted in the formation of a ...
Un metodo basato su LDA per la sentiment analysis
(Universita degli studi di Salerno, 2013-03-16)
La progressiva diffusione dei social network, sia generalisti (quali Twitter, Facebook o Google+, la recente piattaforma messa a punto da Google) sia specializzati (ad esempio le comunità professionali di Linkedin), ha ...
Integrazione delle Fonti Rinnovabili nelle SMART-GRID
(Universita degli studi di Salerno, 2013-03-26)
Energy market liberalization processes and incentive programs by various National governmwnts are driving an increasing diffusion of a wide variety of Distributed Generation (DG) powe plants, causing huge changes and ...
Issues in modelling and identification of Discrete Event Systems
(Universita degli studi di Salerno, 2013-03-14)
Discrete Event System (DES) are systems whose behavior is governed by discrete events occurring asynchronously over time and solely responsible for generating state transitions. DESs are particularly used in the field of ...
