Metodi per l'analisi di accessibilità con applicazione al trasporto aereo
(2013-04-05)
This PhD work performs an exhaustive search on accessibility indicators
aimed at quantitative evaluation of the competitiveness of a territory in
general or more in the detail of a transport terminal. The work has
consisted ...
Models and methods for the design of isolated power converters in high-frequency high-efficiency applications
(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)
(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 ...
Text retrieval and categorization through a weighted word pairs approach
(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 ...
Simulation of supply chains dynamics using fluid-dynamic models
(2013-05-07)
The aim of thesis is to present some macroscopic models for supply chains and networks able to reproduce the goods dynamics, successively to show, via simulations, some phenomena appearing in planning and managing such ...
Sliding mode control of DC/DC switching converters for photovoltaic applications
(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
(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 ...
A methodological approach for the analysis of shallow landslides in non-collapsible soils
(2013-04-15)
Shallow landslides in non-collapsible, fine-grained soils are natural phenomena which, due to their simultaneous occurrence over large areas, often cause agricultural production loss, with enormous economic damage.
Although ...
Un metodo basato su LDA per la sentiment analysis
(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 ...
Carbon nanotube based networks, bio-nano-composites and sensors
(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 ...
