The role of basal ganglia and cerebellum in motor learning. A computational model
(2012-04-20)
Our research activity investigates the computational processes underlying the execution of complex
sequences of movements and aims at understanding how different levels of the nervous system
interact and contribute to the ...
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 ...
Efficient indexing and retrieval from large moving object databases through dynamic spatio-temporal queries
(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 ...
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 ...
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 ...
